Tom Boucher	2ea5efc151	enhance(#3911): hooks declare their crash policy (#3960) ... * enhance(#3911): give hooks an exit seam that needs no build ADR-3889 Phase 7 foundation. The 19 shipped enforcement hooks hold 91 of the epic's 128 terminators and cannot reach `terminateNow` today. The obvious route — requiring `gsd-core/bin/lib/cli-exit.cjs`, as gsd-agent-isolation-guard.js already does for two other modules — is rejected. That precedent carries its own warning (#3582): those files are tsc output, gitignored and absent on a raw plugin-marketplace or git-clone install, so the hook must first call ensureRuntimeBuild() to self-heal. Making the module a hook needs IN ORDER TO TERMINATE depend on a build inverts the dependency, and its failure mode is precisely the fail-open this phase exists to remove: a guard that cannot terminate cannot deny. `lint-hooks-runtime-build-seam` already encodes that concern, and Design B would have had to add an ensureRuntimeBuild() call to all 19 hooks to satisfy it. So `hooks/lib/` becomes a third emit location for cli-exit and a fifth for the registry, preserving the invariant `src/cli-exit.cts`'s own header states: it imports nothing but node:fs and its sibling registry, and the generator dual-emits that sibling alongside each copy so a relative require resolves next to whichever copy loaded it. Shipping needed no change — build-hooks.js already declares HOOKS_SUBDIRS_TO_COPY = ['lib']. Proven, not asserted: the two files are copied into an otherwise-empty tmpdir and a child process requires them and terminates — PASS exits 0, HOOK_DENY exits 2 with the payload on both stdout and stderr. That test fails the moment the hooks copy gains a require reaching outside hooks/lib/. Also fixed inline: the registry's fifth target let any `--write` test overwrite the real committed hooks/lib/exit-code-registry.js, because the test helper derived only three of the other output paths. It now redirects all five, and a regression test asserts every committed artifact is byte-identical after a redirected write. Install-tree goldens pick up the two new shipped paths across 11 runtimes — insertions only, no removals. lint:ci was green while they were stale, so this was found by regenerating rather than by a gate. Verification runs on the remote runner. Refs #3911 * enhance(#3911): declare a crash policy, and migrate the write guard Adds `hooks/lib/hook-exit.js` — the hook-facing vocabulary over `terminateNow`, hand-written because the cli-exit copy beside it is generated: allow(payload) exit 0 deny(payload, stderr?) exit 2 crash(onCrash, payload) whichever the hook DECLARED `crash()` takes the policy as a required argument with no default, which is the whole mechanism: fail-open by accident stops being expressible. A hook must name ALLOW or DENY at the call site, and an unrecognized value terminates INTERNAL rather than guessing. Fail-open stays legal; fail-open by omission does not. `gsd-write-guard.js` is the first hook migrated, all 12 sites, and it exposed a gap in the seam. `terminateNow`'s doc comment justified its fd-2 write by citing this hook's `emitBlock` — but modeled it as sending the same bytes to both streams, when `emitBlock` actually sends full JSON to stdout and only the bare `reason` string to stderr, because Kimi's hook bus feeds stderr verbatim back to the model. Migrating as written would have turned a readable sentence into a JSON blob for Kimi-backed agents. #3911 requires both "all 19 hooks terminate through terminateNow" and "no hook's effective default changes". Those are jointly satisfiable only by teaching the seam to carry a distinct stderr payload, so `terminateNow` gains an optional third argument: omitted, behavior is byte-for-byte what it was; a string is written raw, which is exactly the Kimi case. The doc comment's inaccurate claim about emitBlock is corrected in place. Proven rather than asserted: the pre-migration file is reconstructed from HEAD and driven with the same catastrophic-shrink payload as the migrated one — exit code, stdout and stderr all byte-identical. Verification runs on the remote runner. Refs #3911 * enhance(#3911): all 19 hooks terminate through the seam Migrates the remaining 18 enforcement hooks onto allow/deny/crash. An AST walk now reports zero `process.exit(` call sites across every `hooks/*.js` — down from the 91 the census measured. Each hook with an outer catch declares its policy once, at module top, with the reason that policy is right for that specific guard: a read guard that cannot scan must not block the read; a statusline that renders every prompt must degrade rather than crash; an injection scanner must not retroactively block a result already returned. Those sentences are the deliverable — they are what turns fail-open-by-accident into fail-open-on-purpose. No hook's effective default changed. Wiring exposed two defects, both fixed here rather than noted. A SECOND stdout/stderr-splitting site turned up in `gsd-workflow-guard.js`'s `emitForceAddBlock`, matching the pattern already known from the write guard — full JSON to stdout, bare reason to stderr for the Kimi bus. It uses the `stderrPayload` argument added in the previous commit, which is now carrying its second real caller rather than one special case. More seriously, `terminateNow` emitted both streams inside ONE try, so a payload that failed to serialize aborted before the stderr write ever ran. The two windsurf guards write nothing to stdout on a block and only a reason string to stderr, so `deny(undefined, reason)` exited 2 with EMPTY stderr — a deny that silently loses its reason, which is the exact "fails with success" class this epic exists to close. The streams are now emitted independently, each with its own guard, and `undefined` means "nothing to write for this stream" rather than an error. Regression tests inject a throwing write on one fd and assert the other still receives its payload; they fail against the single-try version. Byte-identity was proven per hook, not assumed: each pre-change file is reconstructed from HEAD and driven side by side with the migrated one across its normal path, its deny path, malformed stdin and empty stdin — exit code, stdout and stderr compared. Verification runs on the remote runner. Refs #3911 * enhance(#3911): harden the three shell hooks, and pin every hook's policy `gsd-phase-boundary.sh`, `gsd-session-state.sh` and `gsd-validate-commit.sh` gain `set -euo pipefail`. The expected hazard did not materialize, and that is worth recording: every intentionally-non-zero command in all three is already the condition of an `if`/`elif`, which `set -e` never fires on, and none of them reads a possibly-unset variable or pipes through a grep that may legitimately match nothing. No `|| true` guards were needed. Each hook was still checked command-by-command before the flags went in rather than after. Twenty-one before/after cases across the three hooks — disabled and enabled, planning and non-planning, missing STATE.md, malformed JSON, the Kimi payload shape, quoted and unquoted `-m`, valid and over-long Conventional Commits — all match on exit code, stdout and stderr. The hardening is shown to actually fire, not merely added: with a stubbed `node` that fails at the JSON-emit step, phase-boundary and session-state go from silently exiting 0 with empty stdout to failing visibly with the error surfaced. No such case could be constructed for `gsd-validate-commit.sh`, whose every statement already sits inside an if-condition — recorded as unproven rather than claimed. `tests/hooks-crash-policy.test.cjs` adds the per-hook coverage the issue asks for, table-driven over all 19 hooks rather than 76 hand-written cases: normal allow, deny where a deny path exists, crash-honors-the-declared-policy, and an unclosed-stdin case — the one `process.exitCode` structurally cannot serve. The deny assertions encode each hook's ACTUAL stream split rather than a uniform shape, since four of the six deliberately differ. A drift guard enumerates `hooks/*.js` and fails if a terminating hook is ever added without a row. Writing those tests surfaced two hooks that emit a block decision in their JSON body and exit 0. Both were checked rather than assumed, and neither is a fails-with-success: `gsd-read-injection-scanner.js` is PostToolUse, where the tool has already run and exit 2 has no meaning, and `gsd-cursor-subagent-start.js` follows Cursor's JSON-body protocol. They are deliberately left alone — a mechanical sweep to `deny()` would have broken exactly these two. Verification runs on the remote runner. Refs #3911 * fix(#3838): the commit validator says when it could not validate #3911 claims to subsume #3838. Measurement said otherwise, so this closes it for real rather than by assertion. `set -euo pipefail`, added earlier on this branch, does NOT fix #3838: bash exempts a command used as an `if` condition from `set -e`, and all three of the hook's swallow-and-pass sites are exactly that shape. Verified against the hardened hook with a node shim that fails only the classifier call — a non-conforming commit still exited 0 with empty stdout AND empty stderr, indistinguishable from "your commit conforms". That is the defect verbatim. All three sites named in #3838 now capture the real exit status instead of consuming it as a condition, and each distinguishes its genuine negative from "could not run": - the classifier: 0 = is a git commit, 1 = genuinely not one, anything else = could not classify. Its `node -e` now wraps the require and the call in try/catch and exits 3 on a throw, so a broken require chain can never be mistaken for `isGitSubcommand` legitimately returning false — which is the arm that matters, since `token-scanner.cjs` is a gitignored build artifact and a fresh checkout lands there. - the opt-in config read and the JSON command extraction get the same treatment. On "could not run" the hook emits a diagnostic to stderr naming which check failed and why, then exits 0. The issue confirms this is safe — it is a PreToolUse hook, so stderr does not disturb the JSON protocol — and ranks it the smallest sufficient fix. The gate still fails open, but it can no longer do so silently, which is the whole complaint: a validator that disables itself quietly costs more than one that is absent, because it is trusted. Both controls are unchanged and pinned by tests: a conforming commit still passes silently, a non-conforming one still exits 2 with its existing block payload. The defect test asserts stderr is non-empty and names the failure; it fails against the pre-fix hook. Verification runs on the remote runner. Refs #3911, #3838 * docs(#3911): document the hook crash-policy contract Reference and Explanation via a new docs/features fragment (FEATURES.md is generated from it), INVENTORY rows for the three new hooks/lib files, and an ARCHITECTURE note on the hooks section. How-To: docs/how-to/declare-a-hook-crash-policy.md, indexed from docs/README.md — a hook author now has to choose and declare a crash policy, which is more than one step and crosses into which harness protocol their hook speaks. It covers allow/deny/crash, writing an ON_CRASH reason that is actually useful, when a deny needs a distinct stderr payload, the two hooks whose harness reads a JSON-body decision and must NOT use deny(), and what to do when a check cannot run at all — with #3838 as the worked example. Refs #3911 * test(#3911): prove the seam actually ships, and stop hand-rolling temp cleanup Two review findings. The acceptance criterion 'hooks/dist/** stays in parity via the build seam (lint:hooks-runtime-build-seam)' was misstated and unmet: that lint checks something else — that a hook requiring a compiled gsd-core/bin/lib module also calls ensureRuntimeBuild(). Nothing exercised that the three new hooks/lib files reach hooks/dist/lib at all. That gap is not theoretical: #770 is a recorded ship-blocking bug where a new hook never shipped because a copy list missed it. The suite now builds dist through the repo's own ensureBuiltHooks(), byte-compares each shipped copy against its source, and spawns a child that requires the SHIPPED dist copy and denies — which is what catches a copy that exists but cannot resolve its sibling registry. gsd-validate-commit.sh hand-duplicated mktemp/run/rm three times; one idempotent trap on EXIT replaces them, guarded so cleanup cannot alter the exit status. Behavior-neutral across five cases, with temp-file counts taken before and after each run. Refs #3911 * fix(#3911): stage transitive hook lib requires, not just one level The remote run returned 7 failures across 3 real causes. The important one is a PRODUCTION bug this phase exposed rather than caused. `writeCursorHooksJson` scanned each hook script for `./lib/X` requires exactly one level deep and never re-scanned the lib files it staged for their own sibling requires. Nothing had a transitive lib dependency before, so the gap was invisible. Adding hook-exit.js -> cli-exit.js -> exit-code-registry.js made real Cursor installs ship a bundle that dies at require time with MODULE_NOT_FOUND. It now walks to a fixed point, and a real installed Cursor hook runs to completion. The staging harness in shared-hooks-dir-resolution hand-copied its fixture, so the injection scanner crashed at require time and its exit-1 was being read as a policy decision. Migrated to copyScriptWithDeps, which walks the require graph — the repo's recorded rule for this class, since adding another copyFileSync keeps it alive for the next person. The missing-lib-source test in cursor-hook-workspace-roots hardcoded which lib file it expected to be named in the abort message; the same throw now fires for a different file first. Its assertion is unchanged in substance — staging still must abort rather than ship a broken hook — only the name is no longer pinned. The last one was my own test asserting an uppercase reason code. Measured against origin/next: the pre-change hook emits the same lowercase 'config_unreadable', so the test was wrong, not the migration. Corrected to the real value rather than making the code match the test. Verification runs on the remote runner. Refs #3911 * chore(#3911): regenerate the cursor install-tree golden The staging fix means a Cursor install now correctly carries the two transitive lib files it was silently missing. Additive only — no path was removed. The golden diff is the evidence the packaging defect was real. Refs #3911 * chore(#3911): backfill the changeset PR number Refs #3911 * fix(#3911): a git probe that timed out is not a negative A macOS CI lane failed three deny cases at 2084ms, 2112ms and 2177ms — just past the 2000ms budget these hooks give their git probes. The three that passed took 72ms, 595ms and 651ms. Under shard contention `git rev-parse` overruns, the hook reads the non-zero result as "not a git repo", and allows with exit 0 and empty stdout AND empty stderr. Under load, the guards silently stop guarding. That is ADR-3889's thesis exactly, sitting inside the security hooks this phase is about. The repo had already recognized the class in one place — gsd-cursor-subagent-start.js fail-closed-denies on `git_timed_out` (#3045) — but nowhere else. `hooks/lib/git-probe.js` classifies a probe's outcome, distinguishing a real non-zero exit from ETIMEDOUT, a signal kill, and a spawn failure, rather than folding all four into `status !== 0`. Three guards route their eight git probes through it. The resolution is the same shape #3838 took, and the same one that issue endorsed as smallest-sufficient: fail open, but loudly. **No exit code changes on any path** — a developer on a loaded machine is still not blocked, which keeps #3911's declaration-pass contract intact for exit codes. What changes is that the hook now says on stderr which probe could not answer, instead of presenting silence as a clean verdict. Scope was checked across every hooks/*.js, not just the three that failed: gsd-agent-isolation-guard spawns no git; gsd-statusline's two probes gate only a cosmetic display segment, not an allow/deny decision, and are left alone. The C2 deny assertion was a real-race test — it demanded exit 2 while a slow git legitimately yields 0. It now requires the hook to either deny, or allow with a diagnostic naming the probe that could not run; a silent allow still fails, so the assertion is not vacuous. A deterministic regression stubs git on PATH to sleep past the budget rather than waiting for load to reproduce it. Verification runs on the remote runner. Refs #3911 * test(#3911): a PATH shim cannot intercept the hooks' git spawn on Windows The deterministic timeout regression stubbed git on PATH and asserted the guard reports rather than silently allows. It passes on Linux and macOS and failed on Windows in 83ms and 176ms — the stub was never invoked at all. Mechanism: the hooks call spawnSync('git', args) with no shell:true, so on Windows CreateProcess resolves git.exe only and never a PATH .cmd shim. The git.cmd branch could not have worked and is removed rather than left implying a Windows path that does. Adding shell:true to the hooks to serve a test would change product behavior and widen an injection surface, so the case is skipped on win32 only, with the mechanism written into the skip reason so a future reader does not 'fix' it that way. Linux and macOS keep the coverage, and macOS is where the underlying fail-open was actually caught. Refs #3911 --------- Co-authored-by: sim <sim@local>	2026-08-27 22:21:10 -04:00
Tom Boucher	9410f7e6e6	enhance(#3897): ADR-3473 §8.3 rungs 2-4 — runtime marker, derived Codex sandbox, short-form depends_on (#3941) ... * test(#3897): failing-first coverage for §8.3 rungs 2-4 ADR-3473 §8.3 has four rungs; #3883/PR #3896 shipped the first. This pins the other three RED before any fix. Rung 2 — the install marker has four readers and resolveRuntime is not one. resolveRuntime resolves GSD_RUNTIME > config.runtime > 'claude' and reads no marker at all, while bin/install.js writes one (#2297) and FOUR hand-rolled readInstallRuntimeMarker copies exist: src/model-resolver.cts:65 (cached, with test seams), hooks/gsd-agent-isolation-guard.js:112, and TWICE in hooks/gsd-cursor-subagent-start.js at :346 and :355. Four copies of one rule. Fixtures and seam names mined from PR #3382 rather than re-derived; it implemented this rung and was closed "not on the merits". Rung 3 — the sandbox map, and the fallback that was the real defect. Measured across all 35 files in agents/, deriving workspace-write iff tools: declares Write or Edit: - all 11 CODEX_AGENT_SANDBOX entries derive to their mapped value exactly, zero disagreements — the map carries nothing the contract does not - 24 roles fall through `|| 'read-only'`, of which 16 declare Write or Edit So the map is redundant and the silent fallback is the defect. The maintainer chose to derive but hold those 16 at read-only pending the question of whether Codex enforces sandbox_mode or merely advises; HALT.md records it. T20 asserts the emitted sandbox_mode PER ROLE against a captured baseline, not in aggregate — an aggregate passes while one role silently widens, which is the proxy-instead-of-identity shape this repo names. T24 and T25 fail on a stale hold, so the hold list cannot rot into the subset map being deleted. Rung 4 — shortFormToId, recovered rather than invented. I nearly reported this as another wrong §8.3 claim: `git log -S shortFormToId` returns only documentation commits. That was the wrong instrument. Direct inspection of sdk/src/query/phase.ts at 11918dcc3^ shows five occurrences, and the tests match that code rather than a guess at its semantics — including first-write-wins on a duplicate short form. T43 asserts at the consumer's output: the emitted `waves` map from the real CLI, which pre-fix collapses to {"1":[...]} because every short-form edge is dropped. A unit assertion on resolveDependencyId would have passed throughout this defect's life. Observed RED, this tree: rung 2 11/11 fail — no marker rung, no seams rung 3 T23,T24,T25,T26,T30 fail; T28 fails (validate agents passes a TOML whose sandbox_mode disagrees — it checks presence only) rung 4 T42,T44 fail; T43,T49 fail with waves collapsed to a single wave 1 Green and staying green: T20/T21/T22/T27 as captured baselines, #3885's unresolvable-token warning and wave-verdict suppression, and #3785's display-mapping passthrough. If the third tier over-reaches, those go red — that is their job. Disclosed weakness: T45 (a canonical id with no dash is not short-form indexed) cannot be isolated behaviorally, because planMap always masks it. It is a non-crash boundary pin, weaker than the other rows, and is recorded as such rather than presented as equivalent. Design: .gsd/phase/feat-3897-adr3473-83-rungs/40-design.md Test matrix: .gsd/phase/feat-3897-adr3473-83-rungs/50-test-matrix.md Decision: .gsd/phase/feat-3897-adr3473-83-rungs/HALT.md Refs #3897 Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * enhance(#3897): §8.3 rungs 2-4 — one marker reader, a derived sandbox, the third depends_on tier ADR-3473 §8.3 has four rungs. #3883/PR #3896 shipped the first. These are the other three. Rung 2 — the install marker had four readers, and resolveRuntime was not one. resolveRuntime resolved GSD_RUNTIME > config.runtime > 'claude' and read no marker, while bin/install.js writes one (#2297) and four hand-rolled readInstallRuntimeMarker copies existed: src/model-resolver.cts (cached, with seams), hooks/gsd-agent-isolation-guard.js, and twice in hooks/gsd-cursor-subagent-start.js. model-resolver's was already the house idiom, so it was promoted rather than replaced: src/runtime-slash.cts now owns it, and model-resolver plus both hooks delegate. The hooks reach it through ensureRuntimeBuild(), the seam lint-hooks-runtime-build-seam enforces. No import cycle existed - checked both directions before moving anything. The marker is the THIRD rung: env > project config > marker > 'claude'. N1 was checked rather than assumed, and my first reading of it was wrong. A marker holding an unknown name comes back essentially verbatim, which looked like a validation gap. Measured against the env rung with the same inputs - including "../../etc/passwd" and "claude;rm -rf /" - the two are identical, because they share resolveRuntimeNameFromCandidates. N1 asks for exactly that, and it is met. The residual (the shared normalizer normalizes shape, it does not validate against the known-runtime set) is pre-existing on the env rung and plausibly deliberate, since a new runtime should not need a code change. The marker also does not widen the trust boundary in any real sense: it lives inside the install tree beside the code, so anyone who can write it can write runtime-slash.cjs itself. Rung 3 — the map was redundant; the silent fallback was the defect. Measured across all 35 files in agents/, deriving workspace-write iff tools: declares Write or Edit: all 11 CODEX_AGENT_SANDBOX entries derive to their mapped value exactly, zero disagreements. The map carried nothing the contract did not already have, so it is DELETED rather than reconciled. What was actually broken is `|| 'read-only'`, which silently under-granted 24 of 35 roles. 16 of those 24 declare Write or Edit and would widen under derivation. Per the maintainer's decision (HALT.md), they are held at read-only pending the question of whether Codex enforces sandbox_mode or merely advises. Emitted TOML is therefore byte-identical for all 35 roles - asserted per role, not in aggregate, because an aggregate passes while one role silently widens. The hold list self-invalidates. A hold whose role no longer derives broader fails, and so does a hold naming a role with no agents/<name>.md. Without that it would rot into exactly the hand-maintained subset map being deleted, and this commit's own ledger claim would become false over time. Both cases were proved by injecting them and watching them throw. Two committed tests asserted the deleted map's existence and contents. They were pinning the thing being removed, so the tests moved rather than the production code: the 11 role-value pairs survive as a test-local PRE_3897_CODEX_AGENT_SANDBOX baseline, and the assertions now drive the real derivation against real agents/*.md. The coverage is preserved; only its source moved out of production code. validate agents gains checkCodexSandboxPosture, mirroring the existing checkCodexModelPosture: each installed TOML's sandbox_mode must equal the role's expected value, failing with role, expected and found. It previously checked file presence and manifest completeness only, so a TOML whose sandbox_mode disagreed passed. Rung 4 — shortFormToId, recovered rather than invented. I nearly reported this as another wrong §8.3 claim: git log -S returns only documentation commits. Wrong instrument. sdk/src/query/phase.ts at 11918dcc3^ carries five occurrences, and the implementation here matches that code rather than a guess at its semantics - including first-write-wins on a duplicate short form, deterministic from the sorted plan order. It resolves the bare plan number: depends_on: ["01"] now reaches 26-01-auth-hardening. That is a control-flow change, not a diagnostic one - plans that silently collapsed into a single wave 1 now execute in their declared waves, and execute-phase.md consumes those wave values. In-phase only, by construction: the map is built from this phase's rawPlans, so a same-named short form in another phase does not resolve. #3785's display-mapping passthrough and #3885's unresolvable-token warning and wave-verdict suppression are untouched and stay green. If the third tier had over-reached, those are what would have caught it. Refs #3897 Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * fix(#3897): close a fail-open I introduced, and wire the posture check to its command Two blockers from review. Both are mine, and one is a security regression my own change created. 1. A held role could escape its hold by editing its own frontmatter. The Codex install loop set the sandbox identity from the agent's frontmatter `name:` field rather than from its filename, so the hold lookup keyed off a value the file itself declares: deriveCodexSandboxMode('gsd-doc-writer', <real file>) -> read-only deriveCodexSandboxMode('gsd-doc-writer-x', <same file, name: edited>) -> workspace-write deriveCodexSandboxMode('GSD-Doc-Writer', <same file, name: recased>) -> workspace-write What makes this a blocker rather than a nit is the DIRECTION. The deleted CODEX_AGENT_SANDBOX map had the identical lookup-key quirk, but it was an allowlist: an unmatched key fell back to read-only, which is safe. The new scheme derives workspace-write from the tool contract and uses the hold as a subtraction, so the same mismatch fails OPEN. I converted a fail-closed quirk into a fail-open one and did not notice; the isolated reviewer proved it by execution. Neither safety net caught it. validateCodexSandboxHolds only checks that <key>.md exists, never that a file's derived identity matches its key. checkCodexSandboxPosture looks the canonical source up by the installed TOML's filename, finds nothing for a renamed agent, and treats it as a custom non-roster agent — silently no violation. The identity is now the FILENAME STEM, which is what validateCodexSandboxHolds already validates and what an attacker editing frontmatter cannot change without renaming the file — at which point the existing validator catches it. The lookup is case-insensitive so a recase does not slip past either. The frontmatter name still drives the TOML body and filename, unchanged; only the sandbox identity moved. All 35 roster files were checked: name matches filename stem everywhere, so a stricter "they must agree or throw" invariant would have been safe against real content. It is deliberately NOT added — it would abort an install on a tampered file where emitting a correctly-derived read-only TOML is the safer outcome. Recorded as a fork rather than decided silently. 2. checkCodexSandboxPosture was exported and never called. cmdValidateAgents (src/verify.cts) called checkAgentsInstalled and checkCodexModelPosture only; grep for the sandbox check in that file returned nothing. So criterion 3 — "validate agents fails on semantic drift, not only on missing files" — was unmet, and `validate agents` behaved exactly as before. That is ADR-3473 Decision 2's named shape: a declared policy with no executor. It also meant the T28 test asserted at the helper's return value while the COMMAND stayed broken — the ADR-3180 Decision 4(b) failure this epic exists to close, committed by me while enforcing it elsewhere in the same epic. Now wired as an additive `sandbox_posture` field beside `codex_posture`, following the sibling precedent exactly. Drift is report-only, not a non-zero exit, because that is what checkCodexModelPosture does — two sibling posture checks disagreeing about whether a violation is fatal would be its own defect. The choice is recorded in a comment rather than left implicit. A consumer-output test now drives the real CLI and asserts on the emitted JSON, and was shown failing before the wiring and passing after. Also corrected a stale artifact: the design's Known limit L1 still claimed rung 3 was not in this deliverable, written while it was halted and false once the maintainer unblocked it. Verified after both fixes: the three bypass probes all return read-only, the per-role table is 35/35 byte-identical, and both hold self-invalidation cases still throw. Refs #3897 Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * docs(#3897): the marker rung, the derived sandbox, and the bare plan-number depends_on Reference: the runtime precedence ladder in docs/CLI-TOOLS.md gains the install marker rung; docs/COMMANDS.md documents validate agents' new sandbox_posture field; docs/reference/plan-md.md documents that depends_on accepts the bare plan number. Explanation: a docs/features fragment keyed id 3897, so it cannot collide with a concurrent PR hand-allocating a section number, regenerated into FEATURES.md. ADR-3473 §8.3 gains an ANSWER blockquote in the document's own correction style, recording what was measured and built against the section's 2026-08-26 correction - including the qualification that checkAgentsInstalled itself still checks presence only, and the semantic assertion lives in a sibling wired into validate agents rather than folded into it. No how-to. Both user-visible changes are zero-step: a non-Claude install resolving its own runtime, and plans executing in their declared waves, both happen without the user doing anything. docs/how-to/control-the-reported-host-runtime.md covers a DIFFERENT ladder (resolveReportedRuntime / agent_runtime) that this change does not touch, and was deliberately left alone rather than edited by association. No tutorial - nothing multi-step to walk through. docs/AGENTS.md unchanged: it documents Claude-side tools frontmatter, never Codex sandbox_mode, and the emitted tools contract did not change. The prompt layer documents depends_on only by example, not by schema, so nothing there needed editing - and few-shot-examples/plan-checker.md already showed depends_on: ['01'], which now actually resolves. Translated copies of plan-md.md are untouched; the project treats translations as community-maintained. Refs #3897 Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * fix(#3897): move the sandbox derivation out of the installer, off the install path, and off a third parser The full suite came back with 26 failures across four files. Three distinct causes, mapped individually rather than assuming the first explained the rest. A. Requiring bin/install.js printed the GSD banner to stdout and corrupted `validate agents` JSON. Unexpected token '', "[36m ██"... is not valid JSON checkCodexSandboxPosture reached deriveCodexSandboxMode by lazily requiring bin/install.js, whose module load prints the ASCII banner. So the command emitted banner bytes before its JSON and every JSON consumer broke, including ten tests that predate this branch. src/ reaching into bin/ was backwards layering that happened to also be loud. The derivation now lives in src/codex-agent-toml.cts - the existing Codex TOML domain module, no new module and no six-gate ripple - and both bin/install.js and src/agent-install-check.cts import it. One owner, which is §8.3's rule applied to the fix for §8.3. B. The stale-hold throw fired on a legitimate partial source dir, and masked a security assertion. validateCodexSandboxHolds treated "this hold's .md is absent from the install SOURCE dir" as a stale hold and threw. A test fixture, or any partial install source, legitimately contains a couple of agents. Worse, it threw BEFORE the path-escape check, so a test asserting that a `../../evil` frontmatter name is rejected got my unrelated error instead of the traversal rejection it was written for. A fail-closed check of mine was hiding a real security check. The "no stale holds, shrink-only" invariant is a property of the repo's canonical agents/ roster, not of whatever directory an install happens to read. It is off the runtime path and enforced where it belongs, in the tests that already existed for it. A partial source dir now installs cleanly, and the evil-name case throws with its own escapes-configHome message again. C. T8 depended on ambient process.env state. The marker/env parity assertion round-tripped through live process.env. It now compares against resolveExplicitRuntime's already-exported dependency-injection parameter - deterministic and hermetic, same claim. Proven still falsifiable rather than assumed: with the marker rung's normalization temporarily bypassed the two rungs diverge ("codex\n../../etc/passwd" vs "codex-../../etc/passwd") and the assertion fails, then passes again once reverted. One correction folded in along the way. The first version of the move added private _extractFrontmatterAndBody/_extractFrontmatterField helpers to codex-agent-toml.cts - a THIRD copy of frontmatter extraction, where the graph already shows two (bin/install.js:2348, runtime-artifact-conversion.cts:893). Adding a third inside the epic whose thesis is one implementation per rule is not defensible. deriveCodexSandboxMode no longer parses anything: it takes (identity, toolsValue) and each caller supplies the tools value using the extractor it already has. Both helpers are deleted. The identity argument is still the filename stem, so the fail-open fix is untouched. Verified after all three: `validate agents --raw` emits parseable JSON with no banner and both posture fields; the four hold-bypass probes still return read-only; the per-role table is 35/35 byte-identical at 26 read-only / 9 workspace-write; the hold list is still 16. Refs #3897 Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * fix(#3897): drop a dev-only transitive dep, make the derivation total, retire a stale fallback test Suite down to 7 failures from 26. Three more causes, mapped individually. A. My extractor import dragged in a script that does not exist in an installed tree. Cannot find module '../../../scripts/fix-slash-commands.cjs' Chain: src/agent-install-check.cts imported runtime-artifact-conversion.cjs, which requires command-roster.cjs, whose line 36 requires ../../../scripts/fix-slash-commands.cjs. That path exists in the repo and not in an install, so every test exercising a synthetic install dir died at module load. I picked that extractor for convenience without checking what it pulls in - the same mistake that produced the banner bug, one layer further out. agent-install-check now uses a single-purpose extractToolsLine on codex-agent-toml.cts. That is deliberately NOT a general frontmatter parser: we deleted those helpers a commit ago for good reason, and this reads one line. Verified from outside the repo root that requiring either module prints nothing and does not throw. B. A test pinned the deleted name-based fallback. 'defaults unknown agents to read-only' called generateCodexAgentToml with a fixture declaring tools: Read, Write, Edit. Under derivation an unknown agent with a writing contract correctly derives workspace-write - design row S6, a new writing role gets the contract, not the pin. The behavior it asserted was the silent fallback this rung deleted; identity no longer decides the sandbox. Replaced with two rows rather than a flipped string: no tools declared -> read-only (absence is not a grant), and Write/Edit declared -> workspace-write. Strictly more coverage than the row it replaces. C. The stale-hold check still threw per derivation call. Last commit took the roster-existence check off the install path, but deriveCodexSandboxMode itself still threw when a hold's role did not derive broader FOR THE CONTENT IT WAS HANDED - so it fired on any synthetic fixture for a held role. The throw is gone, and it cost nothing: if a held role's content does not derive broader, the hold pins read-only and derivation returns read-only anyway, so the hold is a no-op and there is nothing to fail about. The staleness invariant is a property of the real agents/ roster, and validateCodexSandboxHolds still enforces it there - confirmed against the real roster after the change, not assumed. deriveCodexSandboxMode is now total: every (identity, toolsValue) including undefined and null returns read-only or workspace-write, never throws. Verified: validate agents emits parseable JSON; the four hold-bypass probes return read-only; the per-role table is 35/35 at 26 read-only / 9 workspace-write. Refs #3897 Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * docs(#3897): put the rung-3 decision in the shipped docs instead of pointing at an ignored path The ADR entry and the feature fragment both ended their rung-3 explanation with "see .gsd/phase/feat-3897-adr3473-83-rungs/45-decision-rung3-sandbox.md". That directory is gitignored (.gitignore:55), so the rationale for holding 16 roles at read-only was reachable only from the machine that produced it. A reader of the ADR got a pointer to nothing. Both now carry the reasoning inline: the criterion asks both that the sandbox derive from the declared tool contract and that no role gain a broader sandbox, and those cannot both hold, because a faithful derivation widens 16 roles the deleted map never listed and that fell through its silent read-only default. The resolution is derive-and-hold - the derivation owns the rule now, each hold is released as its enforcement question is answered, and a hold is reversible where a widened sandbox that turns out to be enforced is not. Checked before assuming this was a defect class: CONTEXT.md cites .gsd/phase/<slug>/40-design.md as its standard Design: provenance line in eight module entries, and four other shipped docs do the same. Citing a phase artifact is an established convention here, so those are left alone. What was wrong was specific to these two: they put load-bearing rationale behind the pointer instead of provenance. docs/FEATURES.md regenerated from the fragment via scripts/gen-features.cjs rather than hand-edited. Refs #3897 Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * fix(#3897): close a fail-open, stop a silent mis-resolution, and read a declaration as a declaration Two orthogonal reviews on the shipped sha. Three of the findings are the same failure class this epic exists to close, committed inside it. 1. BLOCKER - the sandbox was decided for one identity and applied to another. bin/install.js derived sandbox_mode for the filename stem and then wrote the result to `${name}.toml`, where name comes from the file's own frontmatter. Make the two disagree and a HELD role's artifact goes wide: rename gsd-doc-writer.md -> gsd-doc-writer-v2.md, keep name: gsd-doc-writer -> stem is unheld, derives workspace-write, lands on gsd-doc-writer.toml add any gsd-*.md whose frontmatter name: is a held role -> clobbers that role's toml with workspace-write Both emit read-only on origin/next, because the deleted map was an allowlist and a miss fell back safe. This is a regression my change introduced. The previous review round moved the HOLD KEY off frontmatter to the filename stem and left the OUTPUT PATH on frontmatter; my own comment at install.js:6985 calls that value attacker-editable, four lines above the line that uses it as the filename. The decision is now made over BOTH candidate identities, most-restrictive wins: if either the stem or the emitted name is held, the mode is read-only. 2. MAJOR - hold matching was toLowerCase() only, so confusables escaped. Turkish dotted/dotless i, fullwidth, NFD, trailing space/NBSP/dot/newline, ./ and ../agents/ all slipped the hold and emitted workspace-write. Identities are now basenamed, trimmed of NBSP/zero-width/control characters, NFKC-normalized and lowercased - and anything still carrying a character outside [a-z0-9._-] is treated as suspicious and derives read-only. We do not enumerate confusables; every shipped roster file is ASCII, so refusing to widen on an identity we cannot recognize is fail-closed with no false positives on real content. 3. MAJOR - the short-form depends_on tier mis-resolved SILENTLY. shortFormToId keyed on the last dash-segment of any canonical id with no constraint that it is a plan number, so a phase holding 09-FIX-auth-PLAN.md made depends_on: ["auth"] bind at wave 2 with zero warnings. This is the worst shape in the epic: the unresolvable-token warning fires on a DROPPED token, so a MIS-RESOLVED one is invisible and the tool reports a confident wave assignment built from a wrong edge. A wrong edge is worse than a missing one. The segment must now match /^\d+$/, which is exactly the contract docs/reference/plan-md.md already documents. This tier was recovered verbatim from the retired SDK lineage, which carried the same defect; we are deliberately NOT preserving it bug-for-bug, and the comment says so, so the next reader does not "restore" it. 4. MAJOR - the derivation was reading a declaration as an absence. extractToolsLine read one line, so a YAML list-form tools: block returned only its first item. Two roster files use list form, and gsd-nyquist-auditor declares Write and Edit there - parsed as "- Read", found no write tool, and emitted read-only. Rung 3's headline claim is that sandbox_mode derives from the declared tool contract; that claim was false for 2 of 35 roles and materially wrong for 1. Reading a declaration as an absence is the silent-drop class this epic exists to close. Renamed extractToolsValue and taught it both shapes. gsd-nyquist-auditor now derives workspace-write and joins CODEX_SANDBOX_HOLDS as its 17th entry, per the standing derive-and-hold decision - so emitted TOML stays byte-identical at 26 read-only / 9 workspace-write while the hold list finally records every role that would widen. A previous pass declined this fix because it moved the count; that inverts the priority. Byte-identity is preserved THROUGH the hold, not by leaving a parser broken. Divergence check, because this is where that bug hides: both paths feeding sandbox derivation - install.js's emitter and checkCodexSandboxPosture - now route through the one extractor. The tools readers in runtime-artifact-conversion and install.js's other frontmatter call sites serve Claude-side emission and do not feed sandbox derivation. Also fixed, each real: the posture check's `found` used a naive whole-file regex where its own sibling uses the block-aware scanner, so prose inside developer_instructions produced a false violation; `found` skipped truncatePostureValue and leaked a 300-char value into validate agents output; deriveCodexSandboxMode's absolute never-throws claim was false for an object with a throwing toString; T49 could not falsify cross-phase leakage (its target phase had its own 01, so a globally-scoped map passed too); T20/N6 iterated a hardcoded table and pinned the FIXTURE size, so a 36th agent would be silently unchecked; three tests reimplemented the code they were testing instead of importing it; and T2-T4 deleted GSD_RUNTIME without restoring it. Verified: hold list 17, gsd-nyquist-auditor derives workspace-write unheld and emits read-only held, roster 35/35 at 26/9, depends_on ["auth"] no longer resolves while ["01"] still does, both identity-bypass cases and every confusable vector emit read-only. Refs #3897 Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * docs(#3897): the hold list is 17, and the reason the 17th was missing The count read 16 because the derivation could not read the declaration it claimed to derive from: the tools reader was single-line, so a YAML list-form tools: block returned only its first item and gsd-nyquist-auditor's declared Write and Edit were read as an absence. Both the ADR entry and the feature fragment now carry the corrected count and the reason for it, rather than a silently updated number. Deriving from a declaration you cannot parse is not deriving, and a flattering count is worse than a wrong one because it looks settled. docs/FEATURES.md regenerated from the fragment.

Tom Boucher	adb46cdd85	feat(#2734): surface STATE.md commit-age on the statusline (#3700) ... * test(#2734): failing-first suite for the statusline STATE.md freshness marker Binds the contract before any hook change exists: a `state ~N commits back` segment gated on the state_head stamp landed by #2622, firing at the same advisory threshold /gsd-health's W024 uses rather than at > 0. Covers all five acceptance criteria — threshold parity (19/20/21 boundaries), both renderers including formatGsdStateCompact, an exact spawn-count assertion, repo-pinning and sub_repos degradation, and behavioral parity against readStateHeadFreshness rather than a source-grep of the two fence copies. 52 example-based tests plus 5 seeded fast-check properties. Red now by design. * feat(#2734): surface STATE.md commit-age on the statusline Adds an opt-in `state ~N commits back` marker to the GSD-state segment, consuming the `state_head` stamp and freshness contract landed by #2622. A solo developer returning to a project reads "Phase 4, executing" in STATE.md and acts on it, without noticing the codebase moved 40 commits since that line was written. /gsd-health reports it as W024, but only if you think to run it; the statusline is the surface you see without asking. Fires at STATE_HEAD_ADVISORY_COMMITS (20), the same threshold W024 uses, not at > 0: with commit_docs:true the commit carrying a STATE.md sync advances HEAD by one, so > 0 would alarm permanently on a fresh project. Costs exactly one bounded git subprocess per render and none when disabled. `rev-list --left-right --count` answers ancestry and distance together, and repo pinning is a filesystem check mirroring projectOwnsItsRepo rather than a --show-toplevel compare, which is unreliable on macOS /private/var and Windows 8.3 paths. Every unresolvable input degrades to the tri-state unknown -- the marker is absent, never a "fresh" claim the project cannot substantiate: a malformed stamp, a root that does not own its .git, a sub_repos workspace, history rewound past the stamp, or git being unavailable. Also collapses statusline config resolution onto one resolveStatuslineOptions() seam. runStatusline() and renderStatusline() duplicated it byte-for-byte; one copy is what keeps a newly-added key from reaching only one of them. * test(#2734): route the e2e spawn through the process seam and fix fixture leaks Review findings from the two orthogonal passes: - `bothEntryPointsResolveOptionsIdentically` spawned a child and substring-matched its stdout to test a pure function. It now calls resolveStatuslineOptions() directly — no subprocess, no text matching. - `skipsFreshnessWorkWhenTodoTaskActive` genuinely needs a child (the !task gate lives in runStatusline, which reads stdin), so it now spawns through tests/helpers/process-seam.cjs and proves the negative with a filesystem fact: the git shim appends to a marker file on every invocation, and the assertion is that the marker never appears. Stronger than asserting text is missing, and it drops the last stdout substring match in the block. - Every fixture-creating test now registers `t.after(() => cleanup(dir))` instead of a trailing cleanup(dir), which leaked the temp repo on assertion failure. derivationAgreesWithStateModule reassigns `dir` across five fixtures, so it binds each directory at scheduling time rather than cleaning only the last. Also corrects markerCoexistsWithMilestoneComplete, which asserted the wrong expectation rather than finding a code defect: `percent` drives the progress bar too, so the milestone segment reads "v1.9 [##########] 100%". The marker appends after it, which is what the test exists to prove. CONTEXT.md's opt-in statusline key list was missing statusline.show_git as well as the new key; both are now enumerated. * docs(#2734): backfill changeset PR number (#3700) --------- Co-authored-by: sim <sim@local>	2026-08-20 00:35:01 -04:00
Tom Boucher	bf2332e67c	fix(#3582): route every hook's compiled-module require through the self-heal build seam (#3629) ... * test(3582): failing-first cold-tree coverage and the seam drift lint On a plugin-channel install the compiled gsd-core/bin/lib/*.cjs are legitimately absent (ADR-457 build-at-publish; the npm package builds before publishing, a raw tree materialization never does). gsd-tools.cjs calls ensureRuntimeBuild() before requiring ./lib; no hook does, so the isolation guard's Cannot-find-module lands in its fail-closed catch and is misreported as an unreadable dispatch-isolation configuration, blocking every executor dispatch. These tests fail on that: cold-tree runs of the isolation guard, statusline, cursor guard and update worker, plus the seam's actionable build error surfacing instead of the generic misreport. Also adds the drift lint the acceptance criteria require, with a fixture proving it CAN fail — a guard never shown to fail is worthless. It is red here by design: it flags today's unfixed hooks, which is exactly the defect. * fix(3582): route every hook's compiled-module require through the self-heal seam RED proven at 5b174b0d: 11 failures — the cold-tree runs for the isolation guard, cursor guard and update worker, the fail-closed-with-actionable-message assertion, and the lint's own real-tree check. The compiled runtime library is produced by build:lib and gitignored (ADR-457, build-at-publish). The npm package builds before publishing; a plugin-marketplace or git-clone install materializes the raw tree and never does, so on that channel those modules are legitimately absent. The self-heal seam added by #2002 exists to heal exactly this, and the CLI entrypoint already calls it — no hook did. The isolation guard's Cannot-find-module therefore landed in its fail-closed catch and was reported as 'could not read or resolve dispatch-isolation configuration', so an ARTIFACT ABSENCE was misdiagnosed as an unreadable project config and every executor dispatch was blocked. All SEVEN affected files now call the seam before their first compiled require. The issue named four; a scan found six; implementing it surfaced a seventh — the shared isolation sentinel helper, used by BOTH guards, which requires two compiled modules itself and would have defeated the guards' own fix on a genuinely cold tree. Same defect class, so fixed here rather than left as a known-broken remainder. Failure posture is deliberately split by hook kind: - Gates (agent isolation guard, cursor subagent start) surface the seam's actionable build error distinctly instead of swallowing it into the generic text, and stay fail-closed — a genuinely unreadable project config still DENIES exactly as before. - Cosmetic and detached hooks (statusline, update worker, update check, update banner) DEGRADE rather than crash: the statusline draws on every render and the worker is a detached process, so a build failure there must not take down the prompt. The npm path is untouched: the seam's already-built fast path returns immediately, so prebuilt installs pay nothing and behave bit-for-bit as before. Adds a drift lint, wired into the CI lint chain, so the invariant is enforced rather than remembered — without it the next hook to add a compiled require reintroduces the class silently. It is proven able to fail: a fixture hook requiring a compiled module without the seam is flagged, and one that uses the seam is not. Verified directly — on the unfixed tree it named all seven offenders; with the fix it passes. While writing the lint's comment stripper, a naive whole-text block-comment regex ate its own fixture, because this repo's comments legitimately spell the compiled-lib glob whose star-slash reads as a comment opener. Rewritten as a line-based scanner with a regression test pinning that case. * fix(3582): test the three untested seam call sites and assert typed reason codes Two independent reviews converged on the same major gap: the fix wired the seam into seven files but only four had cold-tree tests. The adversarial pass put it plainly — deleting the shared isolation-sentinel helper's seam call would not have failed any test in the diff. That file was my own addition beyond the issue's four, so it shipped untested; that is now closed. - Shared isolation-sentinel helper: its seam call is only reached when .planning is NOT directly under cwd, and every existing cold-tree fixture puts it there, so the early return always fired first. Now covered, and proven load-bearing by mutation: with the call removed the spy records zero seam invocations and the test fails. - update-check hook and update-banner hook: cold-tree tests added asserting the DEGRADED VERDICT — the fallback cache filename, and silent suppression when the package name degrades to null — rather than merely 'did not throw'. The banner hook previously had no test file at all. Standards violation fixed: two tests asserted on free-form prose via assert.match against a JSON reason string, which CONTRIBUTING bans by name — its own BAD example is exactly that. The ESLint rule only covers readFileSync/spawnSync text, so tooling did not catch it. Both isolation guards now emit a machine-readable reason_code from a frozen enum, following the repo's existing REASON convention, and the tests assert that instead. The human-readable message is unchanged for operators; only the assertion target moved. The duplicated degrade boilerplate across the three cosmetic hooks was deliberately NOT extracted, and the reason is recorded at each site: both viable shapes — a path-parameterized helper, or a ceremony-only wrapper — defeat the drift lint's per-file literal co-occurrence check, so extracting would require the lint to special-case its own helper. Triplication is the lesser evil while the lint stays a co-occurrence scan. The lint's header now states what it does and does not catch (literal quoted requires only; hooks/ scan root), so a future reader does not over-trust a guard that a concatenated path or a require inside a non-hooks helper would evade. * chore(3582): regenerate the committed install-tree fixtures Adding a new shipped hook helper changed the install tree, and those fixtures are committed-and-derived (regen:derived / gen:install-tree), so 12 'install tree — <runtime>' tests failed on 541a1913. Regenerated rather than hand-edited. The delta across all 15 runtime fixtures is exactly two lines — the new helper under both its hooks/ and gsd-hooks/ install paths — and nothing else, so the regeneration pulled in no unrelated drift. This is the bookkeeping ripple a new file under hooks/ carries; it was not visible from lint:ci, which passed both before and after. * chore(3582): backfill changeset PR number (#3629) --------- Co-authored-by: sim <sim@local>	2026-08-18 14:11:23 -04:00

All three are replaced by a harness that runs the real hooks/gsd-check-update.js under a fake HOME and observes the config dirs detectConfigDir resolved, via the env the hook hands its worker. Coverage now includes the CLAUDE_CONFIG_DIR precedence cases and the full adjacent-pair search order the deleted static grep only asserted for one pair. tests/security-prompt-injection.security.test.cjs asserted the scanner hook's SOURCE TEXT contained each canonical MARKDOWN_LINK_PATTERNS regex source. It now drives probes through the real hook and asserts the emitted ruleId, with a completeness gate so a new canonical pattern without a probe fails loudly, plus safePredicate parity the text grep never checked. No allow-test-rule marker is added. The now-false marker on check-update-config-dir.test.cjs is removed and its identity-allowlist entry pruned, which the ratchet requires. Refs #3464 * feat(#3523): emit typed findings IR from the read-injection scanner The scanner built a structured findings array internally and discarded the structure when rendering its advisory sentence, so the only thing a test could assert on was that prose. CONTRIBUTING's 'Prohibited: Raw Text Matching on Test Outputs' names that exact situation and prescribes adding the typed surface rather than matching the text. findings is now an array of {ruleId, match} records and the advisory is derived from it through a single renderFinding mapper, so the rendered text and the IR cannot drift. The array is emitted additively on hookSpecificOutput for both the advisory and blocking output shapes. The advisory string itself is unchanged, byte for byte: verified across six payload shapes (single markdown-link hit, 3+ finding HIGH, invisible unicode, unicode tag block, injection-pattern-only, mixed) by running the pristine and modified hooks against identical stdin and comparing. 28 existing assertions across four suites substring-match that string. The #3523 parity assertions now read the IR, and a new test binds the two surfaces together by asserting every MD-LINK ruleId in findings appears in the advisory and that the reported pattern count matches findings.length. Refs #3464 * docs(#3523): document the read-injection scanner output contract The scanner had no subsection under Security Hooks, only a one-line table row. Documents its trigger events, severity thresholds, skip conditions, rule ids, and the findings IR added alongside the advisory. Refs #3464 * fix(#3523): bind every finding family to the advisory, freeze rule ids Two review findings on the typed-IR commit. The parity test filtered on MD-LINK- and so bound only one of the four finding families to the rendered advisory; the other three were covered only by the pattern count, which catches a length mismatch but not wrong text. It now drives a payload producing all four families at once, asserts all four are present so it cannot silently degrade, and checks each one's expected rendering against an expectation table coded independently of the hook's own mapper. The three synthetic rule ids were written twice each — once at the push site, once in renderFinding — so a rename at one site would fall through the generic render branch with no signal. They are now a frozen RULE_IDS constant referenced from both. No string value changed; the advisory remains byte-identical across all six proof payloads.

New src/token-scanner.cts generalizes hooks/lib/git-cmd.js's proven token-walk (#3129 — "has not re-opened"): tokenizeShellLike (quote-aware shell tokenizer, byte-identical port) and indentWidth (bullet-nesting depth). git-cmd.js migrates onto tokenizeShellLike with zero behavior change (parity-asserted against every existing #3129 fixture in tests/worktree-safety.test.cjs's folded block); isGitSubcommand's phases 1-3 (env-prefix skip, executable check, global-option consume) extracted into skipToSubcommand, shared with the new extractBranchArgument (git checkout -b / git branch <name>) — a new capability exercising the seam on the domain the ADR names, not a migration of existing duplicated logic (none existed). Fixes #3169: src/decisions.cts's parseDecisionLines couldn't distinguish a cross-reference bullet nested under an open decision from a fresh malformed declaration attempt. An earlier bold-run-content-classification design was tried and disproven against the repo's own existing FIX-B fixtures (D-02, "no colon no dash") before being adopted — both have identical shape under any content-only rule. Nesting depth (via indentWidth) is the actual distinguishing signal: a bullet indented deeper than the currently-open decision's own bullet is elaboration, folded into its text like a continuation line, never tested against the parse-miss guard. A bullet at the same-or-shallower indent is unchanged. Scope-narrowing disclosed, not silent: of the ADR's four named bugs (#3197, #3169, #2570, #2528), three no longer need this phase's work. were independently fixed and closed since the ADR was authored — #2570's fix is already a correctly-bounded regex per the ADR's own decidability test (no scanner needed); #2528's fix is a deliberate, twice-reviewed non-scanner design (its own code comment records a scanner-based attempt that regressed a symmetric case and was reverted) that this phase does not disturb. Only #3169 required new work. get_impact: isGitSubcommand CRITICAL/196 affected symbols, parseDecisionLines CRITICAL/164 affected symbols (ADR §6 due diligence).

Adds two seeded property tests (mirroring Phase 1/2's fast-check-setup.cjs convention): indentWidth counts exactly a generated leading-space run; tokenizeShellLike round-trips a generated array of whitespace/quote-free words joined with single spaces. The design doc's own "no property test needed" rationale was wrong — it argued no algebraic law applied, but the standard is unconditional for parsing modules regardless of whether one "feels" applicable. Corrected in .gsd/phase/chore-3414-tokenizer-first-seam/50-test-matrix.md. Also fixes two Spec-axis wording drifts the same review found between the design doc and the shipped code (doc-only, no behavior change): extractBranchArgument's documented signature dropped an unused subVariants parameter that was never implemented, and the #3169 fail-first fixture description corrected from "15-decision plan via cmdDecisionCoverageVerify" to the actual compact 3-decision analog via the real blocking gate, check.decision-coverage-plan.

Tom Boucher	0c413bbc9c	chore(#3059): close the ESLint glob-coverage escape and guard it (#3277) ... * chore(#3059): close the ESLint glob-coverage escape and guard it 62 tracked source files matched no `files:` glob in eslint.config.mjs, so ESLint skipped them entirely while `eslint .` still exited 0 — including all 26 files under hooks/, the enforcement machinery itself. Covers 56 of them (eslint-rules/, hooks/, bin/lib/, pi/, examples/, vscode/, the plugin shims, root *.mjs) and allowlists the 6 deliberate must-not-compile brand-typing fixtures with a recorded reason each. hooks/** is covered with n/no-process-exit deliberately off: a hook's whole contract is its exit code, several exits are load-bearing stdin-timeout guards where nothing else terminates the process, and ADR-0012/0174 scope the no-process-exit convention to the Command Routing Hub. bin/lib/ui-safety-gate.cjs is dual-mode, so it keeps the rule live and takes two targeted disables in its require.main===module tail instead. Adds scripts/lint-eslint-glob-coverage.cjs + a node:test drift guard so the class cannot regrow: allowlist entries require a non-empty reason, the list ratchets down only (a stale entry fails), and a tracked-count floor means a broken `git ls-files` fails rather than reporting clean. Closes #3059 * chore(#3059): apply review findings — correct the changeset count, add parser properties Isolated adversarial review, confirmed by rebuilding a byte-for-byte replica of the pre-change eslint.config.mjs: the changeset claimed 44 previously- unlinted files. The real figure is 56 (56 covered + 6 allowlisted = 62). That was user-facing CHANGELOG text and was wrong; corrected, along with three consequential figures in the design record. CLAUDE.md requires a fast-check property test for parsers and budget limits, and listTrackedSourceFiles is a parser. The standards review called this "satisfied in spirit"; it is not. Adds three properties driving the real exported parser through an injected execFile: extension totality/soundness including a trailing terminator, backslash-normalization totality, and CRLF/LF equivalence — the invariant the repo's recurring CRLF defect class breaks. Also de-duplicates the anchor rows onto one shared resolver, kept deliberately independent of the guard's own resolveFileCoverage so an anchor still fails if that resolution regresses, and records in the guard's header why the bin/install.js family is NOT allowlisted: it resolves to 2 rules under ADR-1703, so an entry would trip the allowlist_stale ratchet. * fix(#3059): make the coverage guard's git call container-safe The remote runner reported the guard degrading to `git_failed` on both Node lanes: fatal: detected dubious ownership in repository at '/work' The runner executes in a container where the repo is owned by a different UID, so git refuses to operate on it. The guard's degraded-verdict path worked exactly as designed — it reported the failure instead of throwing or falsely reporting clean — but a guard that cannot run in CI is not a gate. `git ls-files` is now invoked as `git -c safe.directory=* ls-files`. `-c` scopes the override to the single invocation and mutates no config file, and the wildcard is appropriate because this command only enumerates tracked paths in the repository it is already executing inside. Adds a regression test that captures the argv through the injected execFile seam and asserts `-c safe.directory=*` precedes `ls-files`, so the container case is pinned behaviorally rather than by reading the script's source. * chore(#3059): backfill changeset PR number pr:0 placeholder replaced with the real number now that #3277 exists. --------- Co-authored-by: sim <sim@local>	2026-08-09 19:35:34 -04:00
Tom Boucher	27aa40f65e	fix(#3023): stage pi's shared hook bundle outside pi's reserved hooks/ directory (#3175) ... * test(#3023): failing-first guard — pi must not stage hooks in its reserved dir pi reserves <configDir>/hooks as its deprecated extension location and warns on every startup when it exists. Assert a pi install stages the shared hook bundle under gsd-hooks/ instead, manifests it there, and never creates hooks/. Also adds pi to the local-scope dir table in install-shared.cjs: pi was in RUNTIME_META but not LOCAL_DIR_NAME, so scope:'local' resolved path.join(root, undefined) and no local pi install could be exercised. Fails before the fix. Verified via the remote runner. * fix(#3023): stage pi's shared hook bundle outside pi's reserved hooks/ dir pi reserves <configDir>/hooks as its now-deprecated extension location and warns on every startup when that directory merely exists — checkDeprecatedExtensionDirs() guards the warning with a bare existsSync(), unlike its tools/ sibling. GSD staged its shared hook bundle exactly there, and pi's advised remediation (move it to extensions/) would break the adapter's paths and expose GSD's .js helpers to pi's extension auto-discovery. The bundle directory name is now runtime-descriptor-driven: hostBehaviors .sharedHooksDirName, defaulting to 'hooks' so all 18 other runtimes are byte-identical. pi sets 'gsd-hooks'. The name is validated as a single path segment — separators, dot-only segments, trailing dots, absolute paths, NUL, and Windows reserved device names all fall back to the default, because the value is joined onto a user's config root and written to. Renamed in place rather than relocated: hook scripts resolve siblings via __dirname/.., so a depth change would silently break them. - install / uninstall / manifest sites all read the resolved name - pi/gsd.cjs probes gsd-hooks then hooks, so dev checkouts and half-upgraded trees still resolve; the never-throws contract is preserved - new migration 009 retires the legacy pi hooks/ dir on upgrade, using a new non-recursive remove-empty-dir engine primitive (rmdirSync only, symlink-refusing, containment-guarded); ADR-0008 amended accordingly - fixes two latent name-dependencies the rename exposed: the stale-hook scan and the injection scanner's self-exclusion both hardcoded 'hooks' Verified on the remote runner. Closes #3023 * fix(#3023): close review findings and align emitted provenance with the rename Adversarial review found two defects, and the remote runner found four failure clusters. All fixed here. Review BLOCKER — detect-custom-files was blind to the renamed bundle. GSD_PREFIX_MANAGED_DIRS in gsd-tools.cjs hardcoded 'hooks', so for pi the whole gsd-hooks/ tree was invisible to the custom-file scan and user-added files there were never backed up before the next update's clean-install wipe. The dir set now resolves via the .gsd-runtime marker plus the shipped capability registry (never bin/install.js, which is not shipped into installed trees), and falls back to scanning every known candidate when the runtime cannot be determined — over-scanning is safe, under-scanning is the data loss. Review MAJOR — the pi adapter bound to an empty bundle. resolveSharedHooksDir accepted any directory, so an interrupted install left gsd-hooks/ winning over a fully-staged legacy hooks/ and every hook silently no-opped. A candidate now qualifies only if it is non-empty. Remote-runner clusters: - emitted-provenance had no rule for the gsd-hooks/ family; added two pi-scoped rules pointing at the same sources the existing hooks/ rules use. The table is total, so an unattributed family is a hard failure by design. - pi tests in install-minimal-hooks and the install integration suite asserted the old layout; updated to derive the dir name from the descriptor rather than hardcoding either name. - 19 unrelated-looking failures on node22 only were a leaked fs mock: t.after() runs in registration order, cleanup was registered before mock.restoreAll(), and node22's JS rimraf calls the public fs.rmdirSync while node24's native path does not — so the EACCES stub leaked process-wide on one lane. Restore now runs first. Verified on the remote runner. * fix(#3023): honor PI_CODING_AGENT_DIR, ack the rename ripple, fix expandTilde pi resolves its agent dir as PI_CODING_AGENT_DIR ?? ~/<CONFIG_DIR_NAME>/agent (packages/coding-agent/src/config.ts). GSD's pi descriptor declared an empty configHome.env, so a user with that variable set had GSD installed where pi never looks. Added the env name; the dot-home-nested resolver already handled the override, so no resolver logic changed. Also fixes expandTilde in the shared runtime-homes resolver, found while adding that: it hardcoded os.homedir() and ignored the opts.home every caller threads, so EVERY runtime's tilde-valued env override (claude, antigravity, windsurf, pi) silently resolved against the real home. That is a correctness bug and a test-escape hazard — a sandboxed test asserting on a tilde override reached the developer's actual home directory. Now threaded through every branch; behavior with no injected home is unchanged. Adds the emitted-drift ack fragment for the 58 pi paths whose emitted location moved with the rename. The provenance rules satisfy the totality gate; the differential gate needs the ack because the hook sources are byte-unchanged — only the installer's target directory moved. The two hook files this branch genuinely edits stay attributed and are not double-acked. Note on piConfig.configDir: it is read from pi's OWN installed package.json (getPackageDir walks up from pi's __dirname), alongside piConfig.name — a white-label setting for a redistributed pi fork, not a per-project user setting. Documented accordingly rather than treated as an unsupported override. Verified on the remote runner. * fix(#3023): reject blank env overrides, pin adapter/descriptor parity Three review findings, all fixed. A whitespace-only config-dir override was accepted verbatim: the guard was `if (val)`, falsy only for the empty string, so PI_CODING_AGENT_DIR=' ' resolved to a literal three-space directory name instead of falling back to the descriptor default. Fixed across every env-consuming branch — dot-home, dot-home-nested, all three xdg steps, and generic-agents-root — not just pi's. Non-blank values are still never trimmed, so '~/My Agent Dir' keeps working. pi/gsd.cjs's probe list and the descriptor were two independent sources of truth for the bundle directory name; a future rename would have desynced them silently and left every pi hook quiet with no error. The probe list stays deliberate — it must resolve in a dev checkout and a half-upgraded tree, where the registry's answer would be wrong — so this adds the parity assertion the repo's generative-fix-divergence rule calls for: the descriptor value must be the FIRST candidate, and the default must remain present. Changeset body rewritten to cover the two later user-facing fixes it had not caught up with. Verified on the remote runner. * chore(#3023): backfill changeset PR number * fix(#3023): anchor injection-scan patterns and fix a macOS detection hole CI's security job flagged CONTEXT.md:124 — pre-existing prose reading 'not the same fact as a genuinely empty or absent one'. The match was the 'act as a' INSIDE 'f-act as a': the pattern had no left word boundary, so any word ending in act tripped it (fact, impact, contract, artifact, interact, redact, abstract). My four-line CONTEXT.md edit dragged the latent false positive into this PR because the scan is diff-scoped by file but reads whole files. Anchored with (^|[^[:alnum:]]) rather than rewording maintainer-owned prose, which would have left the class alive for the next PR touching any file saying 'fact as a'. Auditing the rest of the list for the same class surfaced a real detection hole: the eval/exec/Function patterns matched a quote via \x27, a GNU-grep-only hex escape. BSD/macOS grep reads it as four literal characters, so single-quoted eval('...')/exec('...') payloads were NEVER detected there while passing on GNU-grep CI. Replaced with a literal apostrophe class. Boundaries were added only where a real word-suffix collision exists; exec, jailbreak, developer mode and the role-manipulation family were audited and deliberately left unanchored. 22 new cases cover both directions — the false positives now scan clean, and every real payload still fires, including the quote/punctuation/start-of-line boundary forms. Also builds this branch's injection test fixture at runtime instead of carrying the literal phrase, so the payload keeps its teeth without tripping the scan.

Tom Boucher	8f75e27554	fix(#3045): fail closed when an executor dispatch drops its resolved isolation (#3069) ... * feat(#3045): deny an executor dispatch that drops its isolation flag Every isolation gate already resolved correctly. The resolved value then reached the executor through a prose instruction telling the model to substitute it into a call the model composes itself, and nothing verified the substitution. When it was dropped, the executor edited and committed in the user's primary checkout with no consent and no warning. A prose backstop would be the same class of artifact as the defect, so this is a shipped PreToolUse hook on the Agent tool. It fires at the instant of the call rather than being read once at the top of a workflow, which is the only placement the model cannot skip. The guard is inert unless it can positively establish that this is a GSD project, that the project resolves to harness isolation, and that the dispatch targets an executor. A non-GSD repo has no invariant to enforce. Where it cannot read the configuration at all, it denies rather than assuming, with its own reason -- a guard that cannot verify must not answer safe. A malformed payload allows rather than throwing. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * feat(#3045): extend the isolation guard to Cursor Cursor is the second of only two runtimes that resolve harness isolation, so shipping the guard for Claude alone left half the exposed surface unguarded while the changeset implied it was covered. The two runtimes fail differently. On Claude the harness flag is a per-dispatch kwarg the model must copy into a call it composes, and the defect is that it can be dropped. On Cursor the flag is --worktree, which applies to the whole session, and the subagent-start payload carries no isolation field at all. There is no flag to check, so the guard verifies the effective state instead: whether the workspace is genuinely running outside the user's primary checkout. That is a stronger check than the Claude one because it tests reality rather than intent, and it is commented so nobody later rewrites it into a flag check. Isolation is established two ways, either sufficient: the workspace resolves to a linked git worktree, or it sits under the worktree root Cursor manages. The second matters because a directory Cursor placed there is a legitimate isolated session even before it becomes a distinct git worktree, where linkage alone would report no repository. Detecting linkage required a new primitive rather than the existing context resolver. That resolver short-circuits on finding a local .planning directory before it ever compares the git directory to the common one -- and an isolation worktree normally has its own checked-out .planning. Reusing it would have read a correctly isolated session as unisolated and denied it, which is the failure direction that gets a guard switched off. The comparison is now its own shortcut-free function that the resolver delegates to after its own shortcut, so existing behavior is unchanged, and the case that would have broken is pinned. The subagent type is checked before any configuration is read, so an unreadable config cannot deny a dispatch this guard would never have enforced against. The input-schema comment on the Cursor hook documented only the fields common to every event and omitted the ones specific to this one. That omission cost a halt during this work; it now documents both. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * fix(#3045): enforce the resolved dispatch decision, not the host capability The guard keyed on the registry's dispatch.isolation, which says only that a runtime is CAPABLE of harness worktrees. The decision that actually governs a dispatch is the one the workflow resolves after gating, and that legitimately comes out as sequential in three documented cases: a project setting use_worktrees false, a per-plan submodule intersection, and the base-check auto-degrade. The workflow tells the model to omit the flag in exactly those cases, and the guard was denying every one of them. The third case matters most. The preceding fix made the base-check degrade on git timeouts and a missing git binary, where it had previously answered "safe". That correction is right, and it means a transient hang now degrades to sequential far more often than before -- so the two changes composed into a trap where the workflow behaved exactly as designed and the guard blocked it. The workflow already resolves isolation in shell, deterministically, which is what makes it a trustworthy source in a way the model-authored call is not. It now records that resolved value through a dedicated verb, and both guards read it first. A fresh record is authoritative, so sequential dispatches pass untouched. Absent or stale, the guards fall back to the capability check combined with the project's use_worktrees setting, which still covers the case that never reaches the workflow. Also widened the matcher to accept Task alongside Agent, since a host that names the tool Task would otherwise leave the guard silently inert while implying coverage; stopped assuming Claude when no runtime is declared, which is the shipped default and would have demanded a Claude-only argument elsewhere; and made a non-git project inert rather than denied, since advising a worktree session is not actionable without a repository. The original diagnosis never modeled sequential mode as legitimate. That omission is what let this through, and it is now recorded there. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * fix(#3045): record at resolution and bind the record to its dispatch Two independent reviews converged on the same failure: the guard was fail-open in a default install, so it did not catch the defect it exists to catch. A shipped project carries no runtime key, which made "runtime not confidently known" the common case rather than a corner one. A record asserting that isolation was required but carrying no flag then fell through to a capability lookup that answered "none", and the dispatch was allowed. The flag itself only arrived from a second shell block -- the same block a model dropping the argument would also skip. A test had pinned that behavior as intended. The record is now written by the resolver, as an unavoidable consequence of asking for the value, rather than by a step the model is told in prose to go and run. A guard against a prose-carried value cannot itself depend on prose. Mode, flag and identifiers are written together and atomically, so the flagless window is gone, and a record asserting isolation with no resolvable flag now denies instead of degrading. Runtime is also resolved from the installer's own recorded default, which makes confident resolution the normal case. The per-plan submodule gate degrades after the phase-level decision and never re-recorded, so a plan that legitimately ran sequentially was denied against a still-fresh phase record. It now records its own, scoped to the plan. A record also authorized any dispatch for four hours. One phase degrading to sequential could silently license an unisolated dispatch in the next. Records now carry phase and plan, the guards require them to match, and the window is minutes rather than hours -- the resolver rewrites it before every dispatch, so a long window bought nothing and only widened the hole. The flag validator rejected any value beginning with two dashes, which is exactly the form Cursor and Windsurf declare, so their real value could never have been stored. Writer and reader also derived the record path differently and diverged inside a linked worktree without local planning state. The predictable path remains a way to silence the control without leaving a trace in the diff. It grants no access an agent with shell does not already have, so it is documented as accepted rather than redesigned around. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * fix(#3045): correct the staleness boundary and unmask a vacuous parity test The remote runner returned twenty failures. One was a real production defect the boundary case existed to catch: a record whose age exactly equalled the staleness window was treated as fresh, so it stayed authoritative for one tick past its own expiry. Freshness is now strictly inside the window. The parity test meant to stop the two guards' executor lists from drifting could never have failed. Its project fixture was a bare directory rather than a repository, so the non-git inert branch answered before the executor list was ever consulted. It asserted agreement it never actually measured. The fixture is now a real repository, like every sibling in the file. A test also asserted that Windsurf declares the worktree flag. It does not -- Windsurf resolves to no isolation by design, having no named concurrent dispatch to isolate. The test claimed a registry fact that was never true, and a comment in the resolver repeated it. Both corrected, and the test now proves what it should have all along: that the parser accepts any bare flag value, rather than one runtime's supposed value. The new guard was missing from the bundled-hook whitelist, which is the surface that decides what actually ships, and the per-plan gate had gained calls to the launcher without the preamble those calls require. The changeset carried parenthetical product descriptions the purity rule forbids.

Node resolves the home directory from USERPROFILE on Windows and never consults HOME, so both silently read the real runner profile, found no recorded runtime, and asserted against a project the hook had not recognised. The production code was already correct in asking the platform rather than the variable; only the tests were wrong to assume one variable answers everywhere. The helpers now mirror the override onto both. The symlink spoofing test also created a directory symlink unconditionally, which needs elevated privileges on Windows. It survived on this runner, but it would fail on any host without them, so the creation is now attempted and the test skips explicitly when it cannot be done -- a bare return would have counted as a pass and hidden the gap. Skipping alone would have left the platform uncovered, so the behaviour it proves is now also driven in-process through an injected realpath, following the seam already used for the clock. That case no longer depends on privileges at all, and the end-to-end test keeps its original assertions wherever symlinks work.

These tests prove the RED before the fix lands. Uses shared saveSessionEnv/restoreSessionEnv/clearSessionEnv helpers now added to tests/helpers.cjs (single source of truth for the session-env-var save/clear/restore pattern also used by tests/active-workstream-store.unit.test.cjs, which is updated here to consume the same shared helpers instead of its own local, already-diverged copy). Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * fix(#2850): resolve active workstream in the statusline readGsdState only ever walked up looking for a flat .planning/STATE.md; it had no branch for .planning/workstreams/<ws>/STATE.md and never consulted GSD_WORKSTREAM or the stored active-workstream pointer, so the GSD-state segment silently vanished in workstream-mode projects with no root STATE.md (exit 0, no diagnostic). Reuses the existing CLI>env>store resolution seam (resolveActiveWorkstream, active-workstream-store.cts) and the existing mode-detection/path-building seam (listAvailableWorkstreams/planningPaths, planning-workspace.cts) rather than re-implementing either inline. When workstream mode is detected but nothing resolves, readGsdState now returns a {noActiveWorkstream:true} sentinel that formatGsdState/formatGsdStateCompact render as "no active workstream" -- observable, never silent emptiness. Flat-mode behavior and the case where a resolved workstream has no STATE.md yet are both unchanged. Adds active-workstream-store.cts's peekActiveWorkstream: a read-only sibling of getActiveWorkstream. resolveActiveWorkstream's default store lookup self-heals a stale/invalid pointer by deleting it (adapter.clear()) -- correct for a command, but not for a renderer invoked once per prompt, which must never mutate persistent, possibly cross-session state as a side effect of drawing a screen. The statusline now injects peekActiveWorkstream via resolveActiveWorkstream's own getStored override, keeping the env>store precedence itself fully reused while removing only the store tier's write side effect.

Golden install fixtures and INVENTORY regenerated; regression tests negative-controlled (16/16 RED with the hook absent, 16/16 GREEN with it present). * chore(#2255): backfill changeset pr number to 2301 * enhance(#2255): address review — fail-closed reads, typed block output, registration, property test Review fixes for trek-e's CHANGES_REQUESTED on PR #2301: - Blocker 2: register gsd-write-guard.js in BUNDLED_GSD_HOOK_FILES (no-shipping-drift test). - Blocker 3: update the always-on hook enumerations in ADR-766 and CONTEXT.md from six to seven. - Major 4: fail CLOSED on non-ENOENT read errors — only a missing file (new-file Write) passes; EACCES/EISDIR/ELOOP/etc now block, with a typed readError field and the override still honored. Tested, with a negative control against the pre-fix hook. - Major 5: fast-check property test for the SHRINK_RATIO/FLOOR_LINES budget contract (blocked ⟺ newLines < oldLines*SHRINK_RATIO above the floor; sub-floor always exempt), boundary examples pinned. - Major 6: block output now carries typed oldLines/newLines/ overrideEnvVar fields; tests assert on those instead of regexing the free-form reason string. - Minor: CURATED_PATTERNS are case-insensitive (case-insensitive-FS bypass on macOS/Windows); limit+1 boundary tests added for both the floor and the ratio. * enhance(#2255): engage the write guard on Kimi's native payload shape The guard shipped with Claude-vocabulary checks (tool_name 'Write', tool_input.file_path), which #2304 showed leaves a guard dormant on Kimi: the [[hooks]] matcher is registered pre-translated but kimi-cli forwards its native payload verbatim — tool_name 'WriteFile' (bare or module-qualified) and tool_input.path per its tool schemas (src/kimi_cli/tools/file/write.py). The guard matched, saw an unknown name, and exited 0. Apply the same per-guard normalization PR #2326 gives the three sibling guards (name + field mapping, inlined — hook scripts stage as standalone files), and write the block reason to stderr as well as stdout JSON: Kimi feeds stderr, not stdout, back to the model on exit 2, so a stdout-only reason blocks without telling the model why or naming the documented override. Regression tests pipe Kimi-shaped payloads (engage, qualified-name, stderr-reason) plus exemption pins (StrReplaceFile stays out of scope by design; non-curated paths pass) — verified red against the pre-fix guard, green after. * enhance(#2255): rebase onto next; regenerate golden-parity fixtures * enhance(#2255): wire the escape hatch into complete-milestone's reorganize step Review Blocker 1: the guard hard-blocked /gsd:complete-milestone's ROADMAP reorganize — the tree's only legitimate milestone reset and the exact caller GSD_ALLOW_PLANNING_SHRINK was built for. The reorganize step now performs the rewrite through a shell write with the hatch set on the command (a hook inherits the runtime env, so a bare Write cannot carry a per-step override), and a binding test derives the env var name from the guard's typed output and asserts (a) the workflow step sets it and (b) the guard passes the identical catastrophic payload under it — so the next complete-milestone.md edit cannot silently re-break the wiring. * enhance(#2255): drop dead Edit-class mapping from normalizeKimiPayload Review Major 1: StrReplaceFile -> 'Edit' and the old_string/new_string reconstruction were unreachable-by-effect — the guard exits 0 for any tool_name !== 'Write', so nothing ever read the fields they set, leaving guaranteed-surviving mutants against the Stryker bar. The map now carries only WriteFile -> 'Write'; the StrReplaceFile exemption test message states the fall-through it actually exercises. * enhance(#2255): review minors — American spellings; writeSync before exit(2) Minor 1: normalised/normalise -> American house style. Minor 2: the two block paths wrote stdout+stderr via async pipe writes then exit(2) — async-on-Windows, unflushed at exit; fs.writeSync(1/2, ...) makes the block payload durable. * enhance(#2255): assert stderr equals the typed reason, not raw prose Minor 3: the last raw-text match in the suite pinned override-name prose on stderr. The contract is "stderr carries the reason Kimi feeds back" — now asserted as stderr non-empty and byte-equal to the parsed stdout.reason. * enhance(#2255): bind the write-guard's Kimi normalization into the parity test Review Major 2: the guard's normalizeKimiPayload is a 4th inlined copy with nothing binding it. This extends PR #2326's kimi-guard-normalization-parity test (same path and helpers, authored as a superset so either merge order resolves cleanly): sibling byte-parity is existence-gated zero-or-all — trivially green until #2326 lands, full-strength after — and the write-guard copy is bound semantically (map is the value-inverse of convertKimiToolName; the Kimi name for Write must map, or the guard is dormant on Kimi; the path -> file_path half must be present). Byte-parity is deliberately not asserted for this copy: it legitimately omits the Edit-class mapping (Major 1 — dead code in a Write-only guard). * enhance(#2255): refresh golden-parity fixtures for revised guard + workflow * chore(#2255): regenerate golden fixtures after rebase onto next The committed fixture hashes were generated against a tree predating next's latest 11 commits, which independently modified the same install-parity surface. Rebased onto next and regenerated with `npm run gen:golden`. Verified: against upstream/next the regenerated fixtures differ by exactly this PR's own entries -- hooks/gsd-write-guard.js (new), hooks/managed-hooks-registry.cjs, plugins/gsd-core.js, and gsd-core/workflows/complete-milestone.md. No unrelated drift. * fix(#2255): regenerate workflow size baseline for complete-milestone `complete-milestone.md` grew 31071 -> 32061 (+990) when the round-2 review fix bound GSD_ALLOW_PLANNING_SHRINK=1 into the reorganize step, but tests/workflow-size-baseline.json was never regenerated. The per-file workflow baseline test (issue #1074) failed on ubuntu-latest/22 and both macOS shard 1/3 jobs. The growth is justified: it is the escape-hatch binding requested in review round 2 (the guard must not hard-block the tree's only legitimate milestone reset), not incidental bloat. Regenerated via `npm run size:baseline`; the diff is exactly the one entry. * chore(#2255): regenerate golden fixtures and size baseline after rebase onto next * enhance(#2255): bind the shrink escape hatch mechanically — single-use sentinel the guard consumes Round-5 M1: the per-step `GSD_ALLOW_PLANNING_SHRINK=1 tee` prefix was inert (no PreToolUse hook exists on Bash in this family; the write succeeded by dodging the guard, not by the override firing) and the protection was prose. The hatch is now a transport code consults: complete-milestone's reorganize step arms `.planning/.gsd-allow-shrink` with the target's path, keeps the Write tool as the sanctioned path, and the guard — at the block point only — verifies the sentinel is fresh (15 min) and names the pending target, then CONSUMES it and allows that one write. Path-bound + single-use + freshness keep it from becoming a standing unlock. The env var remains as the interactive transport, where it can actually reach the hook. Regression tests written first (negative control: 3 failed pre-fix): the armed-sentinel Write passes and consumes; stale does not exempt; a token for a different file neither exempts nor is consumed; the binding test now takes the sentinel name from the guard's typed output (overrideSentinel), asserts the step arms it, and asserts the step no longer routes the rewrite around Write via a shell pipe. Also in this commit, same file: - m2: block emission is exception-safe — emitBlock() wraps both writeSync sites in their own try/catch that still exits 2, so an EPIPE can no longer convert fail-closed into the outer catch's fail-open. - Header discloses the two reviewed design limits (cumulative sequential shrink; lexical match vs symlinked paths) per round-5 scoping. * docs(#2255): document the sentinel transport across guard surfaces; changeset ends with the (#2255) parenthetical (m4) USER-GUIDE bullet, INVENTORY row (en + ja/ko/pt/zh), the runtime-hooks-surface registration comment, and the changeset now describe both hatches — the single-use sentinel for workflow steps and the env var for interactive use — instead of implying a per-step env can reach a hook. The changeset's trailing `Resolves #2255.` prose becomes the `(#2255)` parenthetical the repo's fragments use (round-5 m4). * chore(#2255): regenerate derived families on the rebased tree (full sweep) Full generator sweep after rebasing onto next @ the body-parser-patched lockfile: build, gen-inventory-manifest, gen:golden, size:baseline. Every regen delta verified to be either a PR-owned entry (gsd-write-guard.js, complete-milestone.md, INVENTORY/USER-GUIDE) or exact convergence to next's committed value for entries our arbitrary-side conflict resolution had left stale (all 18 runtime fixtures checked mechanically). * test(#2255): use helpers.cleanup for sentinel teardown, not raw fs.rmSync The repo's local/no-raw-rmsync-in-tests rule exists for the Windows-EBUSY retry budget; the sentinel disarm now rides it like every other teardown. * chore(#2255): regenerate derived families after rebase onto next Full sweep on the rebased tree (build -> gen-inventory-manifest -> gen:golden -> size:baseline). Every delta is either a PR-owned entry (hooks/gsd-write-guard.js, its registration surfaces hooks/managed-hooks-registry.cjs and the two plugin buses, gsd-core/workflows/complete-milestone.md) or exact convergence to next's committed value across all 18 runtime fixtures. * chore(#2255): regenerate derived families after rebase onto next @ a5180d96 Rebase onto current `next` (a5180d96) resolved 12 conflicting golden-install-parity fixtures; all regenerated via the full generator sweep (build, gen:golden, size:baseline) rather than a single generator. `lint:generated-sync` reports every generated artifact in sync. All 45 differing fixture keys and the single workflow-size-baseline entry map to files this PR actually touches; no foreign drift. * fix(#2255): remove the stale unguarded reorganize_roadmap step (round-8 blocker) complete-milestone.md carried a second ROADMAP-collapsing step, `reorganize_roadmap`, distinct from the sentinel-armed `reorganize_roadmap_and_delete_originals` this PR wired. It is a vestige of the pre-archive-then-reorganize design: it sits BEFORE archive_milestone, so executing it as written would collapse ROADMAP.md before the archive snapshots the full phase detail — and its Write is exactly the shape gsd-write-guard hard-blocks, with no hatch armed. The file's own success criteria describe only one reorganize outcome (Backlog-preserving, overwrite-in-place — the later step's properties), and archive_milestone points forward to "the reorganize step". Removed rather than wired, per the round-8 review's confirm-and-remove option. A new binding test asserts the sentinel-armed step is the ONLY reorganize step in the workflow, so an unguarded collapse step cannot be silently reintroduced (negative-controlled: fails against the pre-fix tree). Golden-parity fixtures and the size baseline regenerate for the shrunk file; every changed fixture key is complete-milestone.md's own. * test(#2255): document why the read-error injection is a path collision, not an fs monkeypatch Round-8 nit: the non-ENOENT tests inject via a directory-at-target-path collision instead of the repo's fs-method monkeypatch pattern. That is deliberate, not drift — runHook exercises the hook as a spawnSync child process, so an in-process fs.readFileSync patch (the pattern the cited siblings use on require'd, in-process code) can never reach the code under test. Record the reasoning at the injection site. * chore(#2255): regenerate derived families after rebase onto next @ 0d08c320 Rebase onto current next (0d08c320) for the CONFLICTING/DIRTY state. All 32 conflicts were generated artifacts (19 golden-install-parity, 12 install-tree, workflow-size-baseline); resolved arbitrarily and regenerated via a full generator sweep (build, gen:golden, size:baseline, gen-inventory-manifest) rather than hand-merged. No source conflicts. Regen diff verified against the PR's changed-file set: 7 distinct differing keys, all PR-owned (gsd-write-guard.js, managed-hooks-registry.cjs, plugins/gsd-core.js, complete-milestone.md, and their .kimi mirrors). lint:generated-sync clean. * chore(#2255): regenerate derived families after rebase onto next @ 9138271b Conflict set was 20 paths, every one a generated artifact, zero source conflicts — resolved arbitrarily during the replay and regenerated here, per the maintainer's round-9 recipe (never hand-merged). Generator sweep (not just gen:golden): npm run build, gen:golden, size:baseline, gen-inventory-manifest, gen:registry. INVENTORY-MANIFEST came back byte-identical, so the merged value was already correct. Regen diff verified == PR-touched entries: every differing leaf key attributes to a file this PR changes (complete-milestone.md, the guard, managed-hooks-registry.cjs, both plugin buses) — derived from the changed-file set, not a feature-name filter. * fix(#2255): port the #2595 Kimi-payload hardening the base landed for the sibling guards Self-found via the round-10 base sweep: a8b40fa5 (#2547/PR #2595) hardened gsd-prompt/read/worktree-path-guard's normalizeKimiPayload after this PR was authored, and this guard carried all three pre-fix shapes: - `path` now wins outright over a model-supplied `file_path` — kimi-cli's WriteFile schema carries no `file_path`, so a payload pairing a curated `path` with a spurious `file_path: ""` had the guard reading '' and exiting 0 while kimi-cli wrote to `path` (one-key bypass, no crash needed). - null/primitive payloads pass through deliberately instead of throwing into the fail-open catch. - the `file_path` read is typed (`typeof === 'string'`), closing the crash-to-allow on `[]`/`{}` — this is what the base-added kimi-guard-typed-payload-reads scan flags. Negative-controlled: the shadowing payload exits 0 against the pre-fix guard and 2 against this one. * fix(#2255): round 9 Major 2 — stop printing the sentinel recipe in the agent-facing denial The block message ended by telling the blocked agent exactly how to arm the single-use sentinel — handing the #973 actor a mechanical self-authorization in the moment it is blocked. The recipe is gone from the prose; the corrective advice and the env override's name stay (the latter is a #2255 acceptance criterion, and a per-step env prefix cannot reach a hook anyway), and the typed overrideSentinel field stays for the binding tests. The hatch remains documented in USER-GUIDE.md and complete-milestone.md, where humans and the workflow engine read. * fix(#2255): round 9 Minors 1-2 — realpath-resolve the target before the curated match; disclose the /i Linux cost Minor 1: a Write to a non-curated path that symlinks into a curated file was not matched while writeFileSync followed the link — the target is now realpath-resolved before the curated match (ENOENT keeps the lexical resolution so new-file Writes still pass; any other realpath error falls through to the read, which fails closed). Negative-controlled: the symlink payload exits 0 against the pre-fix guard, 2 against this one. Test skips on win32, where symlink creation needs privilege. Minor 2: the header's design-limits block now names the unconditional /i cost on case-sensitive Linux (a genuinely distinct .planning/roadmap.md is also treated as curated) next to the stateless limit, and drops the closed symlink limit. * test(#2255): round 9 Minors 3-4 — CRLF counting pin + a passing Write leaves a fresh sentinel unburned Minor 3: countLines' split('\n') is CRLF-safe for a count (the \r rides along), confirmed by trace in the review — this pins it against this repo's recurring CRLF regressions, on both sides of the compare and at the 40% boundary. Minor 4: consumeSentinelFor runs only after the ratio check would block, so a within-tolerance Write never burns the workflow's token — true by construction, previously un-asserted. * fix(#2255): round 9 Major 3 — correct the stale env-var line in archive_milestone's summary complete-milestone.md's "After archival" bullet still said the reorganize happens "under GSD_ALLOW_PLANNING_SHRINK=1" — the wording from the round-2 design this PR's own history rejected in round 5 (a per-step env var cannot reach a hook; setting it in a Bash step silently does nothing). It now points at the sentinel mechanics the reorganize step actually documents, matching that step and USER-GUIDE.md. * docs(#2255): round 9 Major 1 — user-facing docs state the stateless per-Write limit The changeset and USER-GUIDE described the guard as covering "catastrophically shrinks" with no caveat, while the stateless design was disclosed only in the hook header — an operator reading the shipped docs would conclude iterative erosion is covered. Both surfaces now state the per-Write comparison and the erosion non-goal explicitly, in line with what the guard does. * fix(#2255): round 10 Blocker 1 — arm the hatch in the roadmapper's curated writes gsd-roadmapper Step 7 Writes both .planning/ROADMAP.md and .planning/STATE.md wholesale, and /gsd:new-milestone spawns it against the OUTGOING milestone's files. new-milestone's `phases.clear` archives phase DIRECTORIES, never ROADMAP.md, so nothing compacts it first, and no ordering rule forces /gsd:complete-milestone to run before /gsd:new-milestone. Measured against the shipped hook at the #973 file size (292 lines): a new 4-phase roadmap lands at 18.2% and an 8-phase one at 31.8% — both blocked; only a 12-phase replacement (45.5%) clears. So the collapse is reachable on a first-party flow, which is the failure mode #2255 para 4 says the guard must not have. Arms the single-use sentinel immediately before each Write, one per target (the token is path-bound and single-use, so one arming cannot cover both), and gates each arming on `[ -f ]` so the /gsd:new-project path — where the guard already exempts via ENOENT — strands no unconsumed token. Binding test derives the sentinel name from the guard's own typed output, so a rename on either side fails the suite instead of silently unwiring the hatch. Negative-controlled: 2 assertions fail against the pre-fix roadmapper. * docs(#2255): round 10 Major 2 — scope the claim to the guarantee that ships The sentinel is a plain file, so an agent that would reason past an advisory can arm one with a single Bash call it is already permitted to make. The "only defense independent of per-agent tool config" framing outran that, and the changeset was on its way into CHANGELOG.md. Retitles the claim on all three surfaces (changeset, guard header, USER-GUIDE) to what the guard actually delivers: it blocks accidental and single-shot collapse and is not a defense against a determined agent; what it converts is "ignore a sentence" into "take one deliberate, path-bound, single-use, auditable action". Pinned by test on the DURABLE surfaces only — the guard header and USER-GUIDE. The changeset fragment is deliberately not pinned: it is consumed at release, so a test reading it would start failing the moment the release lands. The bound-statement assertion normalizes comment markers and whitespace first, so it pins the claim rather than the paragraph's line wrapping. Negative-controlled: both assertions fail against the pre-fix surfaces. * test(#2255): acknowledge the roadmapper growth from the round 10 Blocker 1 wiring The emitted-attribution gate (#2719/#2767) flags gsd-roadmapper.md growing 1130 bytes without an acknowledgment. The growth is the Blocker 1 sentinel wiring plus the rationale a future editor needs to keep it, so it gets an ack fragment rather than a silencing regen — the gate's own message is explicit that there is nothing left to regenerate. Fragment is PR-scoped (2301-…) per the gate's naming instruction, and uses the plain-string reason form the shipped fragments use. Verified against the TRUE upstream tip, not the fork's origin/next: a stale origin made this same gate report unrelated phantom drift (1 emitted path + 6 grown files + 5 stale acks) that vanishes when GSD_EMITTED_BASE is pinned. * test(#2255): renumber the roadmapper PROSE_ALLOWLIST pin after the Step 7 wiring CI red on shard 2/3, all four platforms. The #2751 gate keys PROSE_ALLOWLIST on {file, line}; the Blocker 1 wiring added 18 lines above the allowlisted parenthetical in agents/gsd-roadmapper.md, moving it 624 -> 642. Both halves of the gate then fired: the moved line reads as a new offender, and the stale entry no longer matches anything. Line content at 642 is byte-identical to what the entry describes — a descriptive "e.g." naming SDK queries a user could run — so this is a renumber, not a re-classification. Swept the defect class rather than the instance: agents/gsd-roadmapper.md is the only line-pinned reference to any file this round changed. Negative-controlled: both assertions fail against the un-renumbered allowlist. --------- Co-authored-by: Tom Boucher <trekkie@nomorestars.com>	2026-08-01 21:19:49 -04:00
0xdhx	cc3ee301a7	fix(#2544): stage the CommonJS marker in GSD-owned dirs, not the config root (#2593) ... * fix(#2544): stage the CommonJS marker in GSD-owned dirs, not the config root installSharedHooksBundle wrote `{"type":"commonjs"}` over <configRoot>/package.json unconditionally — no existence check, no merge, no backup — on every install and every /gsd-update re-install. On the 11 affected runtimes that file is often user-owned; on OpenCode and Kilo it is the documented place to declare local-plugin npm dependencies, so a user's name/type/dependencies/scripts were destroyed on each run. The uninstall path already read the file and unlinked it only on an exact content match. That asymmetry was the defect: the discipline existed in the codebase, it just was not applied on the write side. Move the marker into the directories GSD creates and fills with its own .js files — hooks/ (all shared-hooks runtimes, incl. Kimi's own root) and the nativePlugin dir (plugins/ for OpenCode+Kilo, extensions/ for pi) — and stop writing the config root entirely. New src/commonjs-marker.cts owns the marker string plus one ownership predicate (absent / gsd-owned / foreign, fail-closed on an unreadable file) shared by ensureCommonJsMarker and removeCommonJsMarker, so install and uninstall cannot drift apart again. Nothing else depended on the config-root marker: package identity is baked at build time (#378/#498) and version resolution prefers gsd-core/VERSION and already tolerates a missing root package.json (#1383) — Codex has installed without one all along. A package.json in plugins/ or extensions/ is inert to plugin discovery, which globs *.{ts,js} only (see installer-migration 006). Uninstall retires the pre-fix config-root marker, so upgrading users are cleaned up on removal, and still never touches a file it did not write. * fix(#2544): point the changeset fragment at the filed PR The fragment's `pr:` field is only knowable after `gh pr create` returns. * fix(#2544): register commonjs-marker.cjs in the tsc-generated ESLint ignore set bin/lib/commonjs-marker.cjs is tsc output (src/commonjs-marker.cts is the linted source), so it belongs in the ADR-457 ignore list like its siblings. Clears the lint-tests no-var failure and the repo-invariants "linted xor ignored" migration-state test. * fix(#2544): pin the kimi CommonJS marker to hooks/, not the ~/.kimi root The UPGRADE 1 test still asserted the pre-#2544 marker location (~/.kimi/package.json). The marker now lives inside ~/.kimi/hooks — the directory GSD itself creates — matching the updated golden-install-parity and install-tree fixtures. Also asserts the root marker is NOT written. * fix(#2544): make the CommonJS marker write path non-fatal Review round 2, Major 3 + Minor 1 + the stagedHooks nit. ensureCommonJsMarker rethrew any non-EEXIST write error and neither call site caught it, so EACCES on a read-only hooks/, EROFS, or ENOSPC aborted the whole install with a raw stack trace. Every other marker interaction in the module is best-effort — removeCommonJsMarker swallows unlink failures, classifyMarker swallows read failures — and this was the write path, i.e. the one most likely to fail on a locked-down config dir. It now returns a new 'failed' outcome and both call sites warn and continue. Sibling found while sweeping for the same defect class: fs.mkdirSync sat OUTSIDE the try block, so an unwritable parent threw past the guard entirely. Creating the directory is the same environmental hazard as writing into it, so it moved inside. Also in this file: - The hooks marker is now gated on `stagedHooks && hooksOk`, not stagedHooks alone. stagedHooks is computed from the SOURCE listing before the copy loop, so it stays true when the copies land but verifyInstalled() then fails — marking a hooks/ GSD did not successfully populate claims an ownership the install did not earn. - The uninstall rmdir of the native plugin dir is gated on GSD having actually removed something from it. Hoisting it out of the adapter-exists guard (so the marker-only case could prune) had silently widened it into deleting a user-created but empty plugins/ or extensions/ dir — the same "don't touch territory GSD didn't fill" principle this issue is about, inverted. - Kimi's pre-#2544 marker at its native hook root (~/.kimi) is retired at the same call site that writes its replacement. That path is outside kimi's configDir, so installer-migration 007 structurally cannot reach it. * fix(#2544): retire the stale config-root marker via installer-migration 007 Review round 2, Major 1 — the PR's headline claim was false for existing installs. Upgraders kept BOTH markers: the new one under hooks/ and the stale {"type":"commonjs"} at the config root, so their config root stayed pinned to CommonJS and their dependency manifest stayed gone until they uninstalled. The migration is unusual in one way, and it is the part worth reviewing: the config-root marker was never recorded in gsd-file-manifest.json (writeManifest records hooks/, agents/, commands/, scripts/ and the native plugin, never a root package.json), so classifyArtifact answers 'unknown' for it and the planner's own guard downgrades a remove-managed on an 'unknown' classification to preserve-user. 007 therefore supplies the "purpose-built detector for an old GSD-owned shape" that docs/installer-migrations.md#remove-managed sanctions — exact content match, the same predicate removeCommonJsMarker has always used — and declares the resulting classification on the action. A package.json with any other content is left untouched, and there is deliberately no backup-and-remove branch: a non-matching file here is not a patched GSD artifact, it is somebody else's file. Scope is all runtimes. The `runtimes` field is OMITTED rather than `[]`: validateStringArray requires the field to be non-empty WHEN PRESENT, while the runtime filter treats an empty array as "all" — so `runtimes: []` throws at plan time and the migration never runs. The metadata test pins this. Kimi is a deliberate carve-out, named in the migration's own header: its marker lived at ~/.kimi, outside kimi's configDir, and migration relPaths are structurally confined to configDir. It is retired by the installer instead. Registration: shipped-migrations table, .gitignore for the emitted .cjs, the EXPECTED_CHECKSUMS baseline, and the ESLint ignore set. That last one is not copied from migration 006 by rote — 006 needs no entry because it imports nothing, while 007 imports node builtins, so tsc emits its __importDefault helper and the `var` in it trips no-var. This is the same lint gate that made round 1 red. * test(#2544): fault-injection and multi-runtime marker coverage Review round 2, Major 2 + Minors 4 and 5. Major 2 — CONTRIBUTING.md:514-531 is mandatory for install/uninstall flows and the suite had no fs monkeypatching at all. Every branch now covered is one whose doc comment claims it as the module's safety posture: - classifyMarker non-ENOENT lstat error -> 'foreign' (the fail-closed rule), with an ENOENT control alongside it so the test discriminates rather than just asserting one side - classifyMarker readFileSync throw -> 'foreign' (present-but-unreadable never downgrades to the permissive answer) — the fixture's bytes are exactly GSD's marker, so the test fails if the code ever answers on content it could not read - a DIRECTORY at the marker path (CONTRIBUTING:521; the symlink case was already covered with a real symlink, the directory case needs no injection at all) - the ensureCommonJsMarker TOCTOU EEXIST branch — the entire reason for flag:'wx' - the new 'failed' outcome, for both writeFileSync (EACCES/EROFS/ENOSPC) and the mkdirSync that used to sit outside the guard - removeCommonJsMarker unlink throw -> false These save and restore fs methods in `finally` rather than using chmod 0o000, which does not fault under root and would pass vacuously in root Docker and CI. Minor 4 — uninstall was driven for opencode only. pi's extensions/ and both kimi locations now have behavioral coverage, install and uninstall, each paired with a user-authored-file case proving GSD leaves it alone. Minor 5 — the stagedHooks gate had no assertion behind its stated reason. A pre-existing, GSD-untouched hooks/ directory is now driven through a runtime that declares skipSharedHooksInstall and asserted to stay marker-free, with its user content intact. Also regression-tests the uninstall rmdir gate from the previous commit: an empty plugin dir GSD removed nothing from must survive. * docs(#2544): correct stale marker prose, register the module, document the trade-off Review round 2, Minors 2, 3 and 6. Minor 2 — six files asserted the installed ROOT ships the synthetic marker. None was load-bearing (all three walk-up consumers are VERSION-first with try/catch and the marker never carried a `version`), but ADR-457:52 is the rationale for keeping a generated module, so a future reader would mis-derive the constraint from it. Each site is corrected to what is now true: the installed tree carries no package.json with a .name at all, because the only ones GSD stages are {"type":"commonjs"} markers and they now live in GSD's own directories. Two of the six needed more than a location swap. hooks/gsd-check-update-worker.js and the platform-gate test both described `require('../package.json').name` resolving to undefined; post-#2544 that require does not resolve at all, so the history is kept accurate and the present-tense claim corrected rather than just moved. And src/runtime-artifact-conversion.cts described the no-root-package.json case as Codex-only — it is now every runtime, which strengthens that comment's own argument for lazy resolution. The generated .cjs sibling needs no edit: it is gitignored build output, not a tracked file. Minor 3 — src/commonjs-marker.cts had no CONTEXT.md entry, unlike every peer module, and CONTEXT.md is the #2 co-change partner of bin/install.js. Added, including the fail-closed posture and the never-throws contract. Minor 6 — the plugins//extensions/ marker shadows the config root for all .js siblings, so an OpenCode/Kilo user's ESM plugin/*.js stays broken. That is exactly what #2544's Fix section prescribed and it is disclosed in the PR body, but the PR body is not documentation. It now lives in the OpenCode section of docs/how-to/install-on-your-runtime.md, stated as a real constraint rather than a pure improvement, with the .ts mitigation and a fallback for ESM plugins. * test(#2544): attribute the CommonJS marker in the emitted-provenance rules The differential emitted-attribution gate (#2723, landed on `next` after this branch was cut) went red on the macOS shards once this PR rebased onto it. Two distinct causes, both real gaps rather than noise: 1. `plugins/package.json` and `extensions/package.json` matched NO rule — the `native-plugin` rule covers `*.{js,cjs,mjs}` only, so the marker read as an unattributed emitted family. 2. `hooks/package.json` fell through to `hooks-built`, which attributes an emitted `hooks/<X>` to a repo source `hooks/<X>`. There is no `hooks/package.json` in the repo, so it resolved to a nonexistent path. Cause 2 is exactly the failure already documented three lines above it for Copilot's `gsd-session.json` — "a code literal, not a built script" — so the fix follows that precedent rather than inventing one: `package.json` is excluded from `hooks-built` the same way, and a dedicated `commonjs-marker` rule attributes the family across all four roots it can appear in (both hooks roots plus `plugins`/`extensions`) to the sources that actually emit it. Deliberately a RULE, not an entry in tests/emitted-drift-ack.json. An ack is for a one-off ripple and goes stale by design — the gate fails a stale ack precisely so it cannot pre-clear the next change on that path. These markers are a permanent part of the emitted tree from #2544 onward, so they need standing attribution. Verified by reproducing the CI failure locally with GSD_EMITTED_BASE: 3 provenance errors + 12 unattributed paths before, 35/35 green after. * fix(#2544): route the #2717 hooks-surface marker helpers through commonjs-marker #2717 landed a second copy of ensureCommonJsMarker/removeCommonJsMarkerIfGsdOwned in src/runtime-hooks-surface.cts for the runtimes that stage .js hooks via dedicated paths (cursor/windsurf/codex). That copy had drifted from this PR's module on the two properties that matter: - ownership probe: `fs.existsSync` FOLLOWS symlinks and reports false for a DANGLING one, so a dangling package.json symlink classified as absent and the write went straight through it. Demonstrated: against the pre-fix copy, ensureCommonJsMarker() on a hooks/ dir holding a dangling package.json symlink returns true and creates {"type":"commonjs"} OUTSIDE that directory. - create: a plain writeFileSync leaves the classify->write window open, where commonjs-marker creates with flag:'wx' (O_EXCL). Both helpers now delegate to src/commonjs-marker.cts, which is what this PR's own docstring already claimed was the single place these rules are enforced. Exported signatures are unchanged (still boolean), so bin/install.js and the #2717 tests are unaffected. The new subtest is the only coverage that fails if the duplicate is ever reintroduced — the two implementations agree on every non-adversarial input, so the existing suites pass against both. * test(#2544): pin the stagedHooks gate on zcode, not windsurf The Minor-5 coverage picked windsurf because hostBehaviors.skipSharedHooksInstall kept it out of the shared hooks bundle, so GSD staged nothing into hooks/ and the marker was correctly absent. #2717 changed that premise: cursor/windsurf/codex now stage their .js hooks via dedicated paths and get the marker beside those scripts. Measured on this tree, windsurf stages 2 .js hooks and receives a marker — so the assertion was pinning behaviour that is now wrong, not the gate it was written for. ZCode is the durable choice: per #1821 it has hooksSurface:'none' AND no plugin surface to spawn hooks, so GSD stages no .js there by either route (measured: 0 staged, no marker). The property under test is unchanged — a user-created hooks/ directory GSD never fills stays marker-free. * test(#2544): use the shared cleanup helper in the migration test Addresses the review's Major 1. The suppression's stated reason — "no helpers import available" — was not correct: tests/helpers.cjs exports cleanup, and the other test file added in this same PR imports it (tests/commonjs-marker.test.cjs). The local reimplementation dropped two protections that are live on this repo's windows-latest lane: the CWD guard (Windows cannot remove a directory that is the current working directory) and the 20 x 250ms retry budget that absorbs the deferred-scan handle Windows Defender holds on newly-written files. Local function and suppression both removed; local/no-raw-rmsync-in-tests now passes without one. * test(#2544): expect hooks/package.json for the #2717 runtimes The fresh-install contract table predates #2717, which stages cursor/windsurf/ codex .js hooks via dedicated paths and writes the CommonJS marker beside them. All three therefore now receive hooks/package.json legitimately. Measured on this tree: codex stages 3 .js hooks, cursor 6, windsurf 2 — each with the marker; cline/copilot/trae/zcode stage none and get none, so their contracts are unchanged. * fix(#2544): gate the #2717 marker writes on having staged something The three dedicated marker writers #2717 added ran unconditionally. Each one mkdirs hooks/ up front and stages its scripts conditionally on the source existing, so with an absent or empty hook source they created a directory, filled it with nothing, and marked it as GSD's anyway. That is the same write-into-someone-else's-territory this issue is about, and installSharedHooksBundle already guards the identical case with `stagedHooks`. The dedicated paths now carry the matching gate: - cursor / windsurf: `installedScripts.size > 0` - codex: a new `codexStagedHooks` flag. The enclosing guard only proves that hooks/dist EXISTS; it says nothing about whether any CODEX_HOOKS_TO_COPY entry landed. Covered for cursor and windsurf by driving each writer against a src tree whose hooks/ dir is empty. The codex leg is defensive and deliberately uncovered: its trigger state needs a package tree where hooks/dist exists but holds none of the allowlist, which is not constructible from a real checkout. * test(#2544): scope the commonjs-marker sources per root The rule declared one flat source list for every marker root, so `extensions/package.json` was attributed to runtime-hooks-surface.cts (which never writes there) and `.kimi/hooks/package.json` to install-engine.cts. That is not merely untidy. emitted-diff.cjs accepts the FIRST satisfied source, so a flat list containing bin/install.js let any change anywhere in that 13k-line file authorise marker drift for every root — the blanket escape hatch this file's own agents-verbatim comment refuses for exactly the same reason. Sources are now derived per root from ctx.rel. Note the rule ctx is `{ rel, runtime }` and carries no `root`, so keying on ctx.root would have sent every path down one branch silently. * test(#2544): state precisely what the zcode assertion pins The comment claimed the test pinned installSharedHooksBundle's `stagedHooks` gate. It does not, and neither did the windsurf version it replaced: zcode declares skipSharedHooksInstall, so the outer guard skips that helper entirely and the gate is never evaluated. The test passes on the runtime exclusion. What it does pin — the outcome a pre-existing, GSD-untouched hooks/ stays marker-free — is still worth having, and is what the review asked for. The two `staging zero hook scripts` tests are the ones that pin a real staged-nothing gate. Comment corrected rather than left implying coverage that is not there. --------- Co-authored-by: Tom Boucher <trekkie@nomorestars.com>	2026-08-01 21:00:23 -04:00

Update the parity vocabulary alarm to the new expression. * fix(#2752): make tool_input.path authoritative over model-controlled file_path in gsd-phase-boundary.sh The hook consulted file_path first, path second. kimi-cli executes on path and sends path only; file_path on a Kimi payload is always model-supplied.

0xdhx	a8b40fa53f	fix(#2547): fail closed on crashing and path-shadowing Kimi payloads (#2595) ... * fix(#2547): fail closed on a malformed Kimi edit list in normalizeKimiPayload `normalizeKimiPayload` rebuilt old_string/new_string with `String(e.old ?? '')`. `??` guards the value, not the dereference, so a nullish entry in a Kimi `edit` list threw a TypeError at the top of the handler, before any tool dispatch. Each guard's outer `catch { process.exit(0) }` swallowed that crash and emitted the same exit code as "nothing to report" — turning a should-BLOCK call into a silent allow. Two hard blocks were bypassable: * gsd-worktree-path-guard's cross-git-root write block (#260) — a StrReplaceFile write whose path resolves to a different git root is correctly blocked with a well-formed edit list, and silently allowed with `edit: [null]`. * gsd-workflow-guard's force-add block on agent-* branches — a Shell payload carrying a spurious `edit: [null]` field walks past it. The Bash path never reads `edit`; the field only has to be present to trigger the crash. Fixed with `e?.old` / `e?.new`, landed identically in all five copies so tests/kimi-guard-normalization-parity.test.cjs's byte-identity assertion still holds. The crash boundary is nullish specifically, not "non-object": `('x').old` and `(7).old` are legal reads yielding undefined, so string/number entries never threw. Both are kept as controls proving the fix did not change their behaviour. Regression coverage is folded into the owning suites per CONTRIBUTING.md (no new bug-* files). Negative-controlled: the nullish cases exit 0 against pre-fix guards and exit 2 after, with positive controls (the equivalent well-formed payload blocks) and negative controls (in-worktree writes and benign commands still pass) alongside. Refs #2547 * test(#2547): exercise the production Kimi payload shape in read-guard tests The `#2304: Kimi tool vocabulary engages the read guard` cases send payloads with no `session_id`, and runHook injects none. A live Kimi turn always carries one — kimi-cli's hooks/events.py `_base()` sets it unconditionally, and soul/kimisoul.py calls `set_session_id()` at the top of every turn before tool dispatch, so the ContextVar's `default=""` never reaches a tool call. gsd-read-guard treats any non-empty `data.session_id` as "Claude Code already enforces read-before-edit, skip" (#2520). So the advisory those tests assert fires only for a shape production never sends: the tests were green, and the guard was dormant on Kimi. A sibling #2520 case in the same file asserts the skip when `session_id` IS present — both passed, and the production shape hits the skip. Two changes, test-validity only: * Retitle the #2304 block to say what it proves — the tool VOCABULARY is normalized through to the Write/Edit branch — with a comment warning not to read it as production evidence. * Add a #2547 block asserting behaviour against the production shape (session_id populated), including a case that pins the delta directly: the same payload fires without session_id and is silent with it. The #2547 block characterizes a known gap; it does not endorse it. Redesigning how the guard discriminates runtimes is explicitly out of scope for #2547. If a later change makes the advisory fire on Kimi these tests are supposed to fail — update them then rather than dropping the coverage. Refs #2547 * docs(#2547): scope the Kimi guard-engagement claim to what Kimi enforces #2518 engaged the guards' Kimi matchers and the release notes describe the result as "All seven guard hooks now engage on Kimi", singling out the prompt-injection read scanner as "the security-relevant guard" taken "from silently dormant to engaged". That is not achievable for the scanner at the emit layer. gsd-read-injection-scanner.js is a PostToolUse hook, and kimi-cli's dispatch never inspects PostToolUse hook results: src/kimi_cli/soul/ toolset.py awaits PreToolUse and honours `result.action == "block"`, but fires PostToolUse via asyncio.create_task() and returns the ToolResult without awaiting it — the done_callback only retrieves the task's own exception. So no output shape the scanner emits can block or flag a Kimi tool call, and `security.injection_blocking` cannot take effect there. Reshaping the scanner's output would not change this; the enforcement gap is in kimi-cli's PostToolUse handling, which is out of scope here. This corrects the claim rather than the code — there is no gsd-core emit fix that would make it true: * .changeset/2304-kimi-guard-tool-name.md — the fragment is unreleased, so it would otherwise ship this as a CHANGELOG security claim. Headline narrowed to "normalize Kimi's payload shape" and a scope paragraph added naming what actually blocks on Kimi (the two PreToolUse blocks) versus what cannot. * docs/migration/kimi-to-kimi-code.md — the scanner was listed under "Every GSD `PreToolUse` guard"; it is PostToolUse. Corrected, and the "What about the dormant guards?" section now splits enforceable from not-enforceable instead of saying Phase 0 "fixed all seven". * hooks/gsd-read-injection-scanner.js — the same scope note in the file's own Kimi rationale comment, where the next contributor to touch the normalization will actually read it. Comment only; the shared normalization block is untouched and byte-identity still holds. Refs #2547 * chore(#2547): regenerate golden install-parity fixtures for the guard fix The golden install-parity fixtures record a content hash per installed file, so changing the five guard hooks changes their hashes across every runtime's fixture. Regenerated with the full sweep (build, gen:golden, size:baseline) rather than a single generator — running gen:golden alone leaves tests/workflow-size-baseline.json stale and loses CI jobs to a regeneration that looked complete. The size baselines came out unchanged (no workflow or agent bodies touched) and the hash delta is confined to exactly the five guards: gsd-prompt-guard, gsd-read-guard, gsd-read-injection-scanner, gsd-workflow-guard, gsd-worktree-path-guard. Refs #2547 * fix(#2547): guard the String() coercion in normalizeKimiPayload too Found by adversarial review of the first commit, then reproduced against pristine next: `e?.old` closes the nullish dereference but leaves a second route to the same crash-to-allow. `{"toString": null}` is valid JSON, and coercing it throws `TypeError: Cannot convert object to primitive value` — so an edit entry that IS a well-formed object still crashes normalization, still lands in the outer `catch { process.exit(0) }`, and still downgrades a should-BLOCK call to a silent allow. Confirmed on both hard blocks: {"tool_name":"Shell","tool_input":{ "command":"git add -f secret.env", "edit":[{"old":{"toString":null},"new":"x"}]}} -> exit 0 (was) {"tool_name":"StrReplaceFile","tool_input":{ "path":"<main-repo>/src/index.ts", "edit":[{"old":{"toString":null},"new":"x"}]}} -> exit 0 (was) Both exit 2 now. The coercion is wrapped rather than replaced with a `typeof === 'string'` test on purpose. Degrading only the non-coercible entry keeps stringification identical for every value that CAN coerce — numbers, arrays, plain objects — which matters because gsd-prompt-guard scans new_string for injection patterns, and a `typeof` test would silently stop scanning content that reaches that scan today (e.g. `new: ["ignore all previous instructions"]` currently stringifies and is scanned). Verified: zero behaviour change across string, number, bool, null, array-of-strings, nested array, plain object and `__proto__`-keyed input; only the throwing case changes, from crash to ''. Regression cases are negative-controlled against the previous commit: the four new coercion-trap tests fail with only the `e?.old` fix in place and pass with this one. Refs #2547 * chore(#2547): cover the String() coercion vector in the changeset The release note described only the nullish-dereference route. Both routes reach the same fail-open, so both belong in the changelog entry, along with why the coercion is wrapped rather than type-tested. Refs #2547 * chore(#2547): point the changeset fragment at the real PR number The fragment has to exist before `gh pr create` runs, so it carried the issue number as a placeholder. Corrected to 2595 now that the PR is open. Refs #2547 * fix(#2547): make Kimi's `path` authoritative over a model-supplied `file_path` normalizeKimiPayload copied Kimi's `path` into `file_path` only when `file_path === undefined`, so any `file_path` the model chose to include won outright. Every guard reads `file_path`; kimi-cli executes on `path`. The guard therefore inspected one file while the write landed on another. This bypass needs no crash. A payload pairing a cross-root `path` with a spurious `file_path: ""` left gsd-worktree-path-guard reading an empty string and exiting 0, while the identical write without the extra key blocked — the same cross-root write the #260 block exists to catch. The shadowing also preserved a non-string `file_path` (`[]`), which threw inside that guard's path.isAbsolute() and reached its outer `catch { process.exit(0) }`: the same crash-to-allow the rest of #2547 closes, reached through the guard's own read rather than through normalization. Reachability is not speculative. kimi-cli's soul/toolset.py json-parses the model's raw tool arguments and passes that dict verbatim as tool_input to PreToolUse, performing typed validation only later inside tool.call() — after the hook has already decided. So the model controls extra keys in tool_input at the moment the guard runs. kimi-cli's file tools carry no `file_path` field at all (src/kimi_cli/tools/file/write.py, replace.py), so a `file_path` in a Kimi payload is always model-supplied. `path` now wins outright. Overwriting can only ever narrow what a guard inspects to the path that will actually be written, so it cannot under-block. Normalization returns early for non-Kimi tool names, so the native Claude Code contract (file_path governs) is untouched. Landed identically across all five inlined copies; the byte-identity assertion in tests/kimi-guard-normalization-parity.test.cjs enforces that. * test(#2547): cover the file_path-shadowing bypass in the #260 guard suite Four cases, each exiting 0 (bypass) against the pre-fix guards: a spurious empty-string file_path, an in-worktree decoy file_path, and non-string file_path values (array and object) that additionally crashed path.isAbsolute() into the outer catch. Two controls that are not bypass cases and matter as much: - an in-worktree write carrying a cross-root DECOY file_path must still exit 0. Pre-fix this blocked, because the decoy won; the guard now follows the path kimi-cli executes on in both directions, so the fix narrows what is inspected without over-blocking. - a native Claude Edit (no `path` field) must still block on file_path alone. normalizeKimiPayload returns early for non-Kimi tool names, and this pins that the non-Kimi contract did not move. It passes both pre- and post-fix by design. Negative-controlled: run against the pre-fix hooks, the four bypass cases and the decoy control fail, and the native-Claude control passes. * test(#2547): back the totality claim with property tests over fc.anything() This PR claims the fix "makes normalization total over the inputs JSON can express" — a for-all guarantee — while the tests backing it are example-based, each shape added reactively after a crash was found by hand (the String() coercion trap was itself found by adversarial review after the first commit shipped). Example-based tests cannot substantiate a for-all claim; they record the counterexamples someone happened to think of. Four properties over fc.anything(), which is exactly the JSON-expressible domain the claim names: (a) totality over any tool_input (b) totality over any edit list — the crash surface both #2547 fixes targeted (c) `path` always wins over any model-supplied `file_path` (the review blocker invariant: a guard reading file_path can never be aimed at a file other than the one kimi-cli writes) (d) a non-Kimi tool_name passes through untouched — the native Claude contract normalizeKimiPayload is inlined per hook with no runtime binding, so there is nothing to require. The block is extracted from hook source and evaluated via the SAME extraction contract kimi-guard-normalization-parity.test.cjs uses, so a source edit that breaks one breaks both instead of silently testing a stale block. An extraction floor test fails loudly if the extraction yields a no-op. Non-vacuous, and checked rather than assumed: against pristine pre-#2547 `next`, (a), (b) and (c) all FAIL and (d) passes. (a) needed the fix that makes it meaningful — a bare fc.anything() for tool_input passed even against the live defect, because arbitrary generation essentially never invents the `edit` key the crash lives behind, so the generator is biased onto the keys normalization actually reads and unioned back with unbiased input. * chore(#2547): cover the shadowing vector in the changeset and regen goldens Golden install-parity churn is hash-only, on exactly the five hook files this round changed. gsd-phase-boundary.sh is deliberately unchanged. * test(#2547): make the property test able to kill the coercion mutant Review Major 1: the generative test added to stop the NEXT counterexample could not kill the one it was written for. Reproduced the reviewer's matrix independently — against the shipped generator, a mutant reverting `editText` to the unguarded `String(v ?? '')` passed all four properties. Cause, confirmed by measurement: the edit-array ENTRIES were bare `fc.anything()`, which essentially never invents an `old`/`new` key, so `e?.old` was always undefined and `String(undefined ?? '')` never coerced anything. That is the same vacuity the file's own comment describes one level up, reproduced one level down. The review's prescribed fix — bias the entry onto `{old, new}` — is necessary but NOT sufficient, and this is the part worth recording: measured over 20,000 draws, bare `fc.anything()` yields a non-coercible value 3 times (0.015%). At `numRuns: 200` an `old` key holding a hostile value essentially never co-occurs, and the mutant survives the entry bias too. Both levels need biasing — the entry onto the keys normalization reads, and the VALUE onto the shape that actually throws. `{"toString": <non-function>}` is that shape and stays inside the "JSON-expressible" domain the claim names (JSON.parse produces it verbatim); `fc.anything({withNullPrototype: true})` would also kill the mutant but widens the domain past what the PR asserts, so it is not used. Verified: M1 now dies at every seed tried (1/7/42/99/4242/31337, failing within 3-31 cases) while HEAD stays green at all of them. Also closes three coverage gaps the review listed as nits — properties (e) totality over any JSON value as the WHOLE payload, (f) the tool_output → tool_response mapping (including that an existing tool_response is not clobbered), and (g) an empty edit list reconstructing nothing. Property (e) required a one-line fix in the normalizer itself: `JSON.parse ('null')` is null, and null/primitive payloads threw on the `data.tool_name` read — falsifying the "total over the inputs JSON can express" claim. Harmless in practice (the throw landed in the same fail-open catch as the exit 0 it now takes deliberately), but the claim should be true as stated. Landed byte-identically across all five copies. Refs #2547 * fix(#2547): make old_string/new_string authoritative, not merely defaulted Review Major 2: the shadowing class the prior round's BLOCKER closed for `file_path` survived one field over. `old_string`/`new_string` were still reconstructed only `if (input.<field> === undefined)`, so a model-supplied value won. The argument for making `path` authoritative applies verbatim here. kimi-cli's StrReplaceFile schema is `path` + `edit` only (src/kimi_cli/tools/file/replace.py @ 4a550ef) and carries no `old_string`/`new_string` at all, so either key appearing in a Kimi payload is always model-supplied — exactly like `file_path`. Verified end-to-end against the reviewer's payload: a cross-root write carrying `new_string: ""` alongside an injected `edit[].new` left gsd-prompt-guard reading '' and returning at its `if (!content)` guard, so the injection advisory never fired and the reconstructed content was never scanned. `new_string: null` behaved identically. Negative-controlled: both produce empty output against pre-fix source and fire the advisory after. Chose unconditional reconstruction over the offered `typeof` alternative deliberately. A type test closes `""`/`null` but leaves the interesting case open — a benign NON-EMPTY decoy (`new_string: "chore: tidy"`) shadows just as effectively and passes any type test. The new suite includes that case specifically; it is what discriminates between the two candidate fixes. Also pins the kimi-cli SHA in the authoritative-path comment, as requested — it cited file names with no version while the issue pins 4a550ef. Landed byte-identically across all five inlined copies; the parity test's byte-identity assertion holds. Refs #2547 * fix(#2547): close the non-string file_path crash-to-allow at every read site Review Major 3: the crash-to-allow was closed only as a side effect of `path` masking the bad value, while the changeset read as though it were closed outright. Confirmed both of the review's reachability claims: `[]`/`{}`/`42` are truthy, survive the `!rawFilePath` early-out, and throw inside path.isAbsolute() into the outer `catch { process.exit(0) }`; and normalization returns early for native Claude Code payloads (KIMI_TOOL_NAMES has no 'Edit' entry), so `{"tool_name":"Edit","tool_input":{"file_path":[]}}` reached it untouched — this guard's original #260 surface. Reproduced on a real fixture: string cross-root path exits 2, the identical payload with `[]` or `{}` exits 0. Swept the class rather than the instance. Five more untyped read sites across four other hooks, each one line from a type-strict or method-dependent call. Census of what each can actually do: gsd-worktree-path-guard.js:173 BLOCKS -> live bypass (the review's finding) gsd-prompt-guard.js:128 scanner -> silenced the injection scan, the same outcome as Major 2 by another route; verified empirically gsd-workflow-guard.js:206 advisory only (its exit-2 is the Bash force-add path, which reads `command`, not `file_path`) gsd-read-guard.js:141 advisory only gsd-read-injection-scanner.js:213 advisory only gsd-windsurf-pre-write.js:75 ALREADY TYPED — the shape adopted here All six now read typed. The workflow-guard site keeps its truthiness fallback (`(typeof x === 'string' && x) || ...`) because a bare type test would let an empty `file_path` shortcut the `path` fallback. Also declares one swept hit NOT fixed: `gsd-workflow-guard.js:175` reads `command` untyped on a genuinely blocking path. Same shape, but not exploitable — unlike file_path/path there is no second field carrying the executable value, so a non-string command cannot smuggle a real `git add -f` past the block. Left alone rather than widen this PR into the Bash path. The regression gate is a SOURCE-level invariant, not a behavioural one, and that is deliberate: the fixed read and the crashing read are black-box identical — both end at exit 0, one via the catch and one via the early-out. A test asserting exit 0 on a non-string payload passes against the unfixed code, which is the same false-green the review flagged in the existing `['non-string file_path (array)', []]` cases. Repeating it one level up would be no better. tests/kimi-guard-typed-payload-reads.test.cjs fails if any hook regresses to an untyped read (negative-controlled: it reports all five pre-fix sites with correct file:line). The behavioural cases requested — non-string file_path with NO `path` key — are added to worktree-safety.test.cjs and labelled honestly as documenting the explicit fail-open rather than detecting a revert. Also states the relative-path premise (review Minor 5) at the early-out that depends on it: "always safe" holds only while every runtime reaching there resolves relative paths against the tool CWD. Claude Code satisfies it by requiring absolute paths; kimi-cli's resolution behaviour is NOT verified here and is recorded as an unverified premise rather than an asserted bypass. Refs #2547 * docs(#2547): correct the changeset's closed-claim and fold the misattributed note Review Major 3 also flagged the fragment: it said the non-string vector "threw inside that guard's path.isAbsolute() ... `path` now wins outright", which reads as closed when it was closed only conditionally. Rewritten to state what is now true — closed unconditionally at all six read sites — and extended with the Major 2 finding. Review Minor 6 (the #2547 scope note living in a `pr: 2518` fragment) turns out to understate the problem. Rendering the changelog and re-parsing it shows the note is not merely misattributed — it is DROPPED. serializeChangelog emits each fragment as a single `- ` bullet, and parseChangelog terminates a bullet at the first non-continuation line, so everything after a blank line is lost on re-parse. Audited all 44 fragments: exactly one was lossy — 2304-kimi-guard-tool-name.md, losing 656 of 1730 characters, i.e. precisely that second paragraph. Folding it into this PR's fragment fixes the attribution and the silent loss together; all 44 now round-trip losslessly. That same mechanism is why the remaining nit — reformat this fragment's ~2,000-character paragraph for readability — is NOT applied. A paragraph break or a bullet list would silently truncate the entry at the first blank line (verified for both). The single-paragraph form is load-bearing under the current serializer, not an authoring preference. Worth its own issue; noted in the PR thread rather than worked around here. Refs #2547 * chore(#2547): regenerate golden install parity after rebase onto next Rebased onto `next` @ 9138271b (the PR had gone BEHIND by 20 commits; the review's closing nit asked for it). The replay was CLEAN — no conflicts — and that is exactly why this commit exists. These fixtures are one key per installed file, so when the PR pins five hook entries and the base rewrites others', the two edits land on different lines of the same JSON. Git merges them silently and correctly AS TEXT while attesting nothing about whether the merged hashes are still valid. Verified rather than assumed: per-key equivalence against the old base showed the base had moved 22 of the 27 keys this PR pins in every runtime fixture, and tests/golden-install-parity.test.cjs failed on 10 runtimes immediately after the clean rebase. A push without this regen would have gone out red. Regenerated with `npm run build && npm run gen:golden` under a throwaway HOME/CLAUDE_CONFIG_DIR (the generators invoke the installer); live-profile canary clean before and after. Contamination check: every key differing from the base's committed fixture resolves to a file this PR actually touches — the five guard hooks, under both the `hooks/` and `.kimi/hooks/` install layouts, and nothing else. Derived from the PR's changed-file set rather than a feature-name filter, which is what would have mislabelled the registration surfaces. Size baselines re-checked and NOT regenerated: this PR moves no workflow or agent, and the base's own baselines are current (agent-size-budget, workflow-size-budget, workflow-size, update-size-baseline all green). Refs #2547 * chore(#2547): allowlist the field-shadowing security test in the injection scan The new regression suite tripped the repo's own prompt-injection scan — a test for the injection scanner setting off the injection scanner. The fixture has to be a real injection phrase for the test to assert anything: it is precisely the content gsd-prompt-guard must still scan once a model-supplied `new_string` can no longer shadow the reconstructed `edit[].new`. Weakening it to a benign string would make the suite vacuous. Allowlisted rather than obfuscated, because that is this repo's established convention for the class — tests/read-injection-scanner.security.test.cjs, tests/security-prompt-injection.security.test.cjs, tests/prompt-injection-scan.security.test.cjs and four others carry real payloads as test DATA and are listed for exactly this reason. Splitting the literal to dodge the grep would work but would make this one file inconsistent with its five peers and leave the next reader wondering why. Verified with the CI invocation itself (`scripts/prompt-injection-scan.sh --diff upstream/next`): 26 files scanned, 0 findings. The .cjs codebase scan does not cover tests/ and is unaffected (73 tests green). Refs #2547 --------- Co-authored-by: Tom Boucher <trekkie@nomorestars.com>	2026-07-28 18:31:40 -04:00
Tom Boucher	c7c2fe3c2b	fix(#2587): resolve cursor hook workspace from workspace_roots, not cwd (#2680) ... * fix(#2587): resolve cursor hook workspace from workspace_roots, not cwd gsd-cursor-session-start.js and gsd-cursor-stop.js both resolved the project as path.join(process.cwd(), '.planning', 'STATE.md'). Under the cursor-agent CLI, hooks are invoked with cwd set to the Cursor config dir (~/.cursor), not the workspace — so the lookup always missed. sessionStart could only ever emit the "no .planning/ workflow found" nudge and stop's verify-work reminder could never fire, even with .planning/STATE.md sitting in the workspace. Slash commands were unaffected, which is why only the hook layer looked blind. Both hooks already buffered stdin into `raw` and never parsed it; the payload's workspace_roots carries the real path. Multi-root was left open in the report ("first root vs any root"). Resolved forward: prefer the first root that actually carries .planning/STATE.md, so a workspace whose GSD project is not the first root still resolves — strictly better than first-root-only and identical to it in the single-root CLI case. Falls back to roots[0], then to cwd, keeping IDE behavior unchanged if the IDE ever invokes hooks from the workspace. The resolver is duplicated verbatim across the two scripts rather than shared via hooks/lib/: these hooks ship standalone, and a new hooks/lib/ file must be registered in the GENERATED installer's GSD_HOOK_LIB_FILES allowlist — the installer-omits-shipped-file class that yields MODULE_NOT_FOUND at runtime. Per CLAUDE.md "Generative Fix Divergence", the duplication carries a parity assertion so the copies cannot drift. Failing-first, demonstrated by direct invocation with cwd != workspace: pre-fix sessionStart -> "no .planning/ workflow found" stop -> {} post-fix sessionStart -> ".planning/STATE.md is present" stop -> reminder tests/fix-2587-cursor-hook-workspace-roots.test.cjs spawns the real scripts as child processes with a cwd lacking .planning/ and workspace_roots pointing at it. Boundary coverage on the roots array (0 / 1 / 2 entries), plus malformed-JSON fail-open, junk-entry filtering, the parity assertion, and a guard that neither script resolves .planning from cwd again.

MISSED SITE (high). gsd-cursor-subagent-start.js carried the identical defect at line 43 — its own header documents workspace_roots in the input schema, but it resolved .planning/ from process.cwd() anyway. Under the cursor-agent CLI that meant every Cursor subagent (planner, executor, verifier) started with "no .planning/ workflow found" and no phase context. The report named only sessionStart and stop; the defect class was wider. Verified pre-fix vs post-fix by direct invocation with cwd != workspace. 2. SEMANTIC NARROWING (medium). The first cut searched only workspace_roots and fell back to cwd solely when the array was EMPTY. So when roots were supplied but none carried .planning/ while cwd did, the hook reported absent — where the pre-fix code, which always used cwd, reported present. That contradicted the fallback's own stated intent of preserving IDE behavior. cwd is now a CANDIDATE in the search (`[...roots, process.cwd()]`), so the fix is a strict superset of both the old behavior and the CLI fix, never a narrowing. 3. STALE GOLDEN FIXTURES (high, would have failed CI). The golden-install-parity fixtures store a content hash per installed file; these three hooks appear in 13 of the 19 runtime fixtures. Regenerated via `npm run gen:golden` — the diff is exactly the three hook hashes in exactly those 13 runtimes. Tests extended: subagentStart resolution via workspace_roots; the stop hook's absent branch (previously only session-start's was covered); an explicit regression guard that a project at cwd is still found when roots miss; parity now asserts all THREE copies byte-identical; and the cwd guard sweeps the whole RESOLVING_HOOKS list so a future hook in this family cannot be left on cwd. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_015TCwhbMuY37DzRMCfzTABJ * refactor(#2587): extract cursor workspace resolution to a shared hooks/lib module The duplicate-plus-parity-test approach was the wrong call. The reported issue named two hooks; a third (subagentStart) had the identical defect. That is the signature of a systemic problem, and three copies of a resolver guarded by a parity assertion is a divergence risk maintained by hand rather than a fix. hooks/lib/cursor-workspace.js is now the single implementation. All three Cursor hooks require it; none defines a local copy. Divergence is prevented structurally instead of by asserting three copies stay byte-identical. The reason duplication looked necessary was real, and is fixed properly here rather than worked around: Cursor sets hostBehaviors.skipSharedHooksInstall (#2089), so it never reaches the installer's bulk hooks/lib copy — it was the ONE runtime shipping these hooks WITHOUT hooks/lib (verified against all 19 golden fixtures: cursor had the hook scripts, no lib). A naive require would have thrown MODULE_NOT_FOUND at load, BEFORE each hook's own try/catch, wedging every session on precisely the runtime this bug is about. writeCursorHooksJson (src/runtime-hooks-surface.cts) now stages the hooks/lib helpers the staged scripts actually require, discovered by scanning their require('./lib/…') calls rather than a hardcoded name — so a future helper cannot be silently omitted. This is narrower than flipping skipSharedHooksInstall, which would wrongly pull in every shared hook. cursor-workspace.js is also added to GSD_HOOK_LIB_FILES so uninstall and the manifest manage it for the runtimes that do receive hooks/lib. Verified against a REAL install (runMinimalInstall, cursor/global): the helper is staged, and all three INSTALLED hooks resolve the workspace end-to-end from a cwd that is not the project. Also closes the review gap that the stop hook was excluded from the cwd-candidate regression loop — it now sweeps RESOLVING_HOOKS. The byte-parity test is replaced by a structural guard (every hook requires the shared module, none redefines it) plus a new install test asserting the helper is staged and the installed hook actually loads against it. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_015TCwhbMuY37DzRMCfzTABJ * fix(#2587): fail loud on a missing hook lib source; drop unsubstituted version marker Two findings from the installer-focused review. H1 — the staging step's `if (!fs.existsSync(libSrc)) continue;` silently defeated the very guarantee it was added for. Reproduced: delete hooks/lib/cursor-workspace.js from source, run the cursor install — it exits 0, prints "Done!", and ships the three hook scripts with an EMPTY hooks/lib/. The installed hook then throws `Cannot find module './lib/cursor-workspace.js'` at load, before its own try/catch, wedging every session — and nothing surfaces until a user hits it. The scan protected against a required-but-UNLISTED helper while leaving required-but-MISSING wide open (typo, bad rebase, an accidental delete). It now throws: a missing helper source is a packaging bug and aborts the install. M1 — hooks/lib/cursor-workspace.js carried a `gsd-hook-version: <placeholder>` marker that NOTHING substitutes: copyLibDir stamps .sh files only, and writeCursorHooksJson's staging applies just the colon-to-dash rewrite. Verified the literal was reaching disk on both the bulk (--claude) and Cursor (--cursor) paths. hooks/lib/git-cmd.js — the only pre-existing hooks/lib/*.js — carries no such marker, so this was newly introduced, not inherited. Marker removed, matching that precedent, with a note on why. (The explanatory comment deliberately does not spell the token out, or it would reintroduce the literal.) M2 — the require-scan regex demanded the exact compact form, so `require( "./lib/x.js" )` would silently fail to stage its helper and compound H1. Now tolerant of interior whitespace and either quote style. Regression test added for H1 — the reviewer confirmed the invariant had zero coverage repo-wide: a source tree carrying the hooks but no hooks/lib/ must make writeCursorHooksJson throw rather than produce a broken install. Re-verified end to end: the missing-source case throws, no unsubstituted literal ships, and the installed hook still resolves the workspace from a foreign cwd.

Tom Boucher	7e905aa137	feat(#2505): Phase 0 — Kimi PreToolUse guard vocabulary normalization (precondition; carries PR #2326 forward) (#2518) ... * fix(#2304): normalize Kimi tool vocabulary in PreToolUse guard payload checks The Kimi [[hooks]] registrations translate the matcher to Kimi's tool vocabulary (WriteFile|StrReplaceFile) but the guard scripts early-exit unless the payload's tool_name is a Claude name (Write/Edit/MultiEdit), so every guard was dormant on Kimi: the matcher fired, the script saw WriteFile, and exit(0)'d. Normalize the payload's tool_name at the top of each guard (WriteFile -> Write, StrReplaceFile -> Edit; bare or module-qualified kimi_cli.tools.file:* forms) before the check. Inlined per guard rather than a hooks/lib/ helper because hook scripts are staged as standalone files on every hook surface, and a sibling require is a staging dependency that can fail silently. Regression tests pipe Kimi-vocabulary payloads at each guard and assert it engages (typed fields: exit status, decision, hookSpecificOutput) — verified red against the pre-fix scripts, green after. * fix(#2304): normalize Kimi tool_input fields and route block reasons to stderr Cross-AI review of the initial fix, verified against kimi-cli source, found the tool_name normalization alone leaves the guards dormant on a real Kimi runtime: kimi-cli forwards tool_input verbatim (src/kimi_cli/hooks/events.py), and its tool schemas (src/kimi_cli/tools/file/{write,replace}.py) use path/content and edit.old/edit.new (single Edit or list) — not Claude's file_path/old_string/new_string. The guards read file_path, got '', and exited 0 past the now-open tool_name gate. Extend the per-guard normalization to the payload fields (path -> file_path, edit -> old_string/new_string with list flattening), and write the worktree guard's block reason to stderr as well as the stdout JSON — Kimi feeds stderr, not stdout, back to the model on exit 2 (docs/en/customization/hooks.md exit-code table). Regression tests rewritten to Kimi's actual payload shapes (plus an edit-list case and a stderr-reason assertion) — verified red against the name-only fix, green after. * fix(#2304): join all edit[] entries into old_string, matching new_string Review nit on #2326: old_string took only edits[0].old while new_string joined the whole list. Symmetric join removes the latent trap for any future consumer sizing before/after content (e.g. the #2255 write guard). * fix(#2304): normalize Kimi ReadFile vocabulary in read-injection scanner Review Major 2 on #2326: gsd-read-injection-scanner.js had the identical dormancy — its Kimi matcher fires on 'ReadFile' but the SCANNED_TOOLS check only knew 'Read', so injected content in read files was never flagged on Kimi installs. Folds the same inlined normalization block into the scanner and extends the shared KIMI_TOOL_NAMES map with ReadFile:'Read' in all four copies so they stay byte-identical. Harmless in the three write guards: a normalized 'Read' falls out of their Write/Edit allowlist exactly as the unmapped name did. Field mapping verified against kimi-cli upstream (src/kimi_cli/tools/file/read.py Params.path); the existing path->file_path copy covers the scanner's file_path read. * test(#2304): parity test binding the four inlined Kimi normalization copies Review Major 1 on #2326: KIMI_TOOL_NAMES + normalizeKimiPayload is deliberately inlined in four hook scripts (staging-dependency rationale, unchanged), with the inverse table in bin/install.js — five hand-maintained surfaces and nothing binding them. Static binding, zero runtime coupling: - the four inlined blocks must be byte-identical; - each guard-map entry must be the value-inverse of convertKimiToolName() for its Claude name; - every guard-relevant Claude tool (Write/Edit/MultiEdit/Read) must have a reverse entry — a vocabulary rename or extension that updates the installer without updating the guards now fails in CI instead of leaving a guard silently dormant (the #2304 recurrence door). Negative-controlled: diverging one copy or dropping a map entry fails the suite against the fixed code. * test(#2304): regenerate golden parity fixtures for guard hook changes CI red on #2326: all 10 golden-parity failures were the staged guard hooks drifting from their fixtures. Regenerated with npm run gen:golden (after npm run build) under throwaway HOME/CLAUDE_CONFIG_DIR; diff verified to change exactly the four PR-touched guard entries per surface, nothing else. * test(#2304): regression tests for Kimi ReadFile engaging the scanner Mirrors the per-guard Kimi vocabulary tests the PR added for the three write guards: bare and module-qualified ReadFile produce the advisory, path exclusions still apply post-normalization, unknown Kimi names stay fail-open. Negative-controlled against the pre-fold scanner (the two positive cases fail there; exclusion/fall-through correctly pass on both sides). * fix(#2304): normalize Kimi Shell vocabulary in workflow guard Withdraws the disclosed out-of-scope split: verification showed the Bash->Shell case needs NO different mapping — kimi-cli's Shell.Params names its field `command` (src/kimi_cli/tools/shell/__init__.py), same as Claude's Bash — and the guard's write branch (Write/Edit/MultiEdit allowlist) was ALSO dormant on Kimi under its Shell|WriteFile| StrReplaceFile matcher. Same defect class as the other four hooks. Folds the identical inlined block into gsd-workflow-guard.js and extends the shared map with Shell:'Bash' in all five copies (harmless outside the workflow guard: a normalized Bash falls out of the other guards' checks as before). Parity test now binds five copies and adds Bash to the dormancy alarm. New workflow-guard test file exercises the observable block (force-add on a worktree-agent branch): Shell bare and module-qualified block with WORKTREE_AGENT_FORCE_ADD_FORBIDDEN, benign Shell passes, Claude Bash unchanged — negative-controlled against the pre-fold guard (the two Kimi cases fail there). Golden parity fixtures regenerated; diff verified to change exactly the five guard entries per surface. * fix(#2304): map Kimi tool_output and route workflow-guard block to stderr Third-party review (cross-AI verifier) caught two gaps in the revision: 1. Kimi PostToolUse events carry `tool_output`, not `tool_response` (kimi-cli src/kimi_cli/hooks/events.py post_tool_use()), so the read-injection scanner — which reads data.tool_response — was STILL dormant on real Kimi payloads; the earlier tests passed because they sent Claude-shaped payloads. The shared normalization block now maps tool_output -> tool_response (inert in PreToolUse guards, where the field is absent), and the scanner's Kimi tests send the real shape. 2. The workflow guard's force-add block wrote its reason to stdout only. Kimi's exit-2 protocol feeds stderr back to the model — the exact fix this PR already applied to the other blocking guard — so the newly-awakened block would have been a silent denial. Reason now also routed to stderr, asserted in the test. Also: the scanner's "unknown name" test now uses a genuinely unmapped name (FetchURL) — Shell stopped qualifying when it entered the map — and the workflow guard's write branch (WriteFile advisory, StrReplaceFile .planning pass) gains behavioral coverage. All five copies stay byte-identical (parity test green); golden fixtures regenerated, diff verified to the five guard entries per surface. Negative-controlled: 3 new assertions fail against the pre-fix hooks. * docs(#2304): update changeset to cover the full five-guard fix Review round 2 (2026-07-18) flagged the changeset as stale: it was written for the first commit and still described only the three guards named in the issue. The shipped diff grew to five guards plus two payload dimensions the original body never mentioned. The body now names gsd-read-injection-scanner and gsd-workflow-guard, the ReadFile and Shell vocabulary entries, the tool_output -> tool_response mapping, and the workflow guard's stderr block-reason routing. * test(#2304): regenerate kilo golden fixture after #2305 landed on next The branch's fixture sweep predates 50efae13 (fix(#2305), PR #2327), which made Kilo ship the five shared guard hooks. Rebased onto next and re-ran the full generator sweep (gen:golden, size:baseline, and the four registry/contract generators); the only delta across all of them is kilo.json's five guard-hook hashes, matching this PR's hook edits. * fix(#2304): fold Kimi normalization into the two shell hooks The 2026-07-19 review found the last two guards with the #2304 dormancy: - hooks/gsd-graphify-update.sh gated on tool_name == "Bash" but is registered on Kimi with matcher 'Shell' — Gate 1 never matched and the auto-rebuild was silently dormant. kimi-cli's Shell.Params names its field `command` (src/kimi_cli/tools/shell/__init__.py), same as Claude Bash, so only the name needs mapping: strip the module-path prefix, map Shell -> Bash. - hooks/gsd-phase-boundary.sh read only tool_input.file_path, but Kimi's file tools name the field `path` (src/kimi_cli/tools/file/write.py + replace.py) — the hook read '' and .planning/ writes went undetected. Falls back to tool_input.path when file_path is absent, mirroring normalizeKimiPayload's precedence in the JS guards. The normalization is reimplemented in shell — a byte-identity assertion cannot span the JS<->shell boundary, so the parity test gains a shell-guard vocabulary block that pins both scripts' mapping facts to convertKimiToolName's live vocabulary instead of faking a byte binding. Behavior is covered by negative-controlled tests beside each hook's existing suite (verified red against the pre-fix scripts): Kimi Shell dispatch (bare + module-qualified) with a WriteFile negative control in graphify-auto-update.slow.test.cjs, and Kimi path detection, file_path precedence, and a non-.planning negative control in hooks-opt-in.test.cjs. Changeset updated to name all seven guards; golden install-parity fixtures regenerated (diff is exactly the two hook entries per runtime; size baselines unchanged). * fix(#2304): use a Map for KIMI_TOOL_NAMES so prototype keys cannot pass the guard fall-through A bare bracket lookup on an object literal resolves 'constructor', '__proto__', 'toString', 'valueOf' and 'hasOwnProperty' through Object.prototype to truthy functions/objects, so `if (!mapped)` failed to short-circuit and data.tool_name was assigned a non-string. Map.get returns undefined for those keys — the same shape the repo already uses in canonicalizeRuntimeName (src/runtime-name-policy.cts). Applied identically to all five inlined copies (review M1, PR #2326). No new bypass class: unrecognized strings already fail open by design; this fixes the lookup being wrong, not the posture. * test(#2304): enumerate normalized guards by scanning hooks/, not a hardcoded list The parity test's file list was a literal five-entry array — a sixth guard with its own copy-pasted normalization block would be silently uncovered, the exact divergence mode the test exists to prevent (review M2). Now the list is a scan of hooks/*.js for the KIMI_TOOL_NAMES marker, with a floor assertion so a scan that finds nothing fails instead of passing vacuously. Also parses the Map declaration introduced by the M1 fix, and carries the allow-test-rule annotation documenting the source-text scanning (review m4). * test(#2304): parse hook JSON output instead of substring-matching raw stdout workflow-guard.test.cjs asserted on unparsed stdout while read-guard.test.cjs in the same PR parses the JSON envelope first — match the better pattern at all four assertion sites (review m5). * test(#2304): regenerate golden parity fixtures after Map conversion in the five guards * docs(#2304): reset changeset pr:0 placeholder for Phase 0 PR (#2507) The closed PR #2326's changeset carried pr:2326.

Cody Anderson	20ff405cb3	feat(#2162): opt-in compact GSD-state format for the statusline (#2175) ... * feat(#2162): opt-in compact GSD-state format for the statusline New statusline.state_format config, enum full|compact (default full — existing rendering untouched). "compact" renders the state segment as "<version> · P<phase>/<total> · <status>", e.g. "v1.12 · P7/12 · executing" — dropping the milestone name and progress bar (the two biggest width costs) and collapsing narrative statuses to a single keyword. Per the #2162 approval conditions, the keyword set is the canonical vocabulary from normalizeStateStatus() in state-document.cjs (discussing/planning/executing/verifying/completed/paused) — no parallel hand-rolled list, so the vocabularies can't drift — and the canonical stuck state "paused" renders uppercase as PAUSED (no new "blocked" lifecycle state).

Tom Boucher	bd613566cb	feat(#2100): drive Windsurf through the EoS descriptor + wire Cascade's blocking hook bus (ADR-1239) ... Fold all 10 residual isWindsurf branches in bin/install.js onto descriptor-driven hostBehaviors (byte-parity — no fold changes any install output): - 2 dead destructures dropped (uninstall, finishInstall); the dead `else if (isWindsurf)` legacy agent-loop arm removed (windsurf ∈ _DESCRIPTOR_AGENTS_RUNTIMES → unreachable). - skipSharedHooksInstall:true folds the two `!isWindsurf` shared-hooks exclusions. - legacyDevinSkillsCleanup:true folds the `.devin`→`.windsurf` one-time cleanup gate. - installsCommandBodiesForWorkflowDelegation:true folds the #1629 command-body copy (workflow-delegation target — load-bearing; local-install verified intact). - verificationStyle:"windsurf-workflows" folds the workflow-count report. - Corrected stale _LEGACY_SCAN_SUBDIR_NAMES + hooks-json manifest comments (cursor + windsurf). Zero live runtime==='windsurf'/isWindsurf branches remain across bin/install.js, install-engine.cts, surface.cts, runtime-artifact-conversion.cts (AC2 guard scans all four). UPGRADE (Cascade hook bus): wire GSD's write/command safety guards into Windsurf's native hook bus. New hooksSurface 'windsurf-hooks-json' (VALID_HOOKS_SURFACES 7→8, GATE A profile-marker-only allowlist, the HooksSurface union) + writeWindsurfHooksJson (Cursor-templated, Cascade's flat {hooks:{<event>:[{command}]}} shape) writing .windsurf/hooks.json with two BLOCKING pre-hooks: - pre_write_code → gsd-windsurf-pre-write.js: blocks writes to a file outside the active git worktree / into .git internals. - pre_run_command → gsd-windsurf-pre-command.js: conservative destructive-command deny-list (rm -rf of root/home incl. sudo/env/path-prefixed forms; fork bombs; force-push refspec forms — HEAD:main, +main, --force/-f — to main/master/next). Both use Cascade's protocol (stdin JSON, exit 2 + stderr to block, exit 0 to allow, fail-open on error/timeout). Tokenize-based classifier (no catastrophic-backtracking regex; 4096-char cap) with the fail-closed false-positives fixed post-review. The 4 advisory GSD guards + pre_mcp_tool_use + 5 post_* logging events are deliberately NOT wired: Cascade has no context-injection channel for advisory hooks and GSD has no MCP guard — porting them would be non-functional padding (documented; codebuddy #2098 / copilot #2099 faithful-subset precedent). extendedHookEvents stays []. Golden: the 2 guard scripts ship in the shared hook bundle (HOOKS_TO_COPY + the shared managed-hooks-registry), exactly like cursor's 6 gsd-cursor-*.js scripts — so the 8 shared-bundle runtimes' fixtures gain the 2 inert windsurf scripts + the registry hash (functionally inert for non-windsurf; the established cursor pattern). No install-output change beyond that (the folds are byte-parity; skip-bundle runtimes untouched). New scripts registered in managed-hooks-registry + build-hooks + INVENTORY. Tests: declarative-reference- windsurf (adapter/axes/fail-closed + AC2 guard) + windsurf-hooks-bridge (live exit-2 blocking + allow/fail-open + ReDoS-bound + writer/reconcile/remove idempotency); VALID_HOOKS_SURFACES pin updated to 8.

The prompt-level data/instruction boundary is the primary control. - A2: registered security.injection_blocking in the config schema + defaults manifests (default false) + an e2e config-roundtrip test; the dotted setter writes the nested shape the hook reads. - A3: reverted the 4 hand-edited localized security-model.md (canonical EN only, per convention). - A5: ADR-1577 (untrusted-input boundary + opt-in blocking; redaction-vs-circuit-breaker rationale). - A6: property test — scanner never crashes / only emits valid JSON on unicode/large/malformed input. - Also: inventory (untrusted-input-boundary.md) + agent-size baseline (8 ingest agents) + drift-guard matcher update (Read -> Read|WebFetch|WebSearch). A7 (content<20 early-exit) left as the noted pre-existing follow-up. * fix(#1577): allowlist untrusted-input-boundary.md in injection-scan CI gate The new reference quotes injection phrases ('ignore previous instructions', 'you are now…') as examples agents must NOT comply with, tripping the repo's own prompt-injection-scan.sh diff gate (the standalone 'security' CI job, red on HEAD). Allowlist it alongside the other security docs (security-model.md, TEST-EXAMPLES.md) that legitimately demonstrate injection patterns. The JS scanner test doesn't scan references/, so only the shell gate needed it.

Restore them so no named web-ingress agent is uncovered, keeping the two justified additions (gsd-ai-researcher, gsd-domain-researcher). Final set = AC's 8 + 2 = 10. - gsd-ui-researcher carries the full WebSearch/WebFetch + MCP-fetch toolset. - gsd-assumptions-analyzer reads 5-15 codebase source files (external/source- document ingress per the boundary), though it has no web tools. INGEST_AGENTS in the isolation test now asserts all 10; size baselines regenerated (+60 bytes each, both well under the DEFAULT cap); changeset reworded 8 -> 10.

Replace both with text-safe escapes that keep the identical runtime values: '\\x00' and String.fromCodePoint(0xFFFF). File now diffs/blames line-by-line. Verified: property test 2/2; no NUL/raw-noncharacter bytes remain. * docs(#1577): align untrusted boundary docs Name all 10 ingress agents in INVENTORY/security-model and allowlist the intentional read-injection property corpus for the prompt-injection scanner. * docs(#1577): align ADR ingest agent count Update ADR-1577 from 8 to 10 ingest agents so it matches the actual boundary include set and the rest of the docs. --------- Co-authored-by: Tom Boucher <trekkie@nomorestars.com>	2026-06-24 17:07:23 -04:00

Agents, commands, and templates markdown-@-include the canonical ~/.claude/gsd-core/... path (which expands ~ but NOT ${CLAUDE_PLUGIN_ROOT}), so every include resolved to nothing and agents (e.g. the executor) failed. Add a SessionStart hook (hooks/gsd-ensure-canonical-path.js) that, on a plugin install, symlinks the canonical path's immutable subdirs (bin, contexts, references, templates, workflows) to the plugin's bundled gsd-core/ tree. It changes zero @-references, is a no-op in classic installs, preserves user-generated files (USER-PROFILE.md, STATE.md), prunes stale links so it self-heals after `claude plugin update`, uses Windows junctions, and rejects bundled/canonical paths that escape the resolved plugin root (no traversal, no clobber).

Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> * fix(#770): make lifecycle-hook tests deterministic on scoped runner Replace the shared hooks/dist/ ensemble setup (ensureHooksDist / teardownHooksDist) in the Claude hook tests with per-test isolation: pre-populate each test's own tmpDir/.claude/hooks/ with stub files and pass installerMigrations:[] to install() so the first-time-baseline migration does not remove the stubs before the copy step can run. Root cause: hooks/dist/ is gitignored and absent on a fresh npm ci. ensureHooksDist() created it and teardownHooksDist() deleted it, but with --test-concurrency=4 both test files ran concurrently as separate Node.js worker processes sharing the same filesystem. One file's afterEach teardown deleted hooks/dist/ while the other file's install() was copying from it, producing an ENOENT (reproduced 2/10 runs locally). The additional issue: even with pre-placed stubs surviving the copy race, the 000-first-time-baseline migration classified hooks/gsd-*.js as bundled-gsd-hook artifacts, auto-removed them, and the copy step never re-ran (hooks/dist/ absent) — leaving contextMonitorFile missing and all hook registrations silently skipped (the 'got: []' symptom). Fix: pre-populate targetDir/hooks/ per-test (isolated temp dir) AND pass installerMigrations:[] so the baseline scan is skipped.

As a result the hook was never copied into hooks/dist/ during the build, so: - the hook would never ship to users (real production bug — the FileChanged config-reload feature was dead-on-arrival), and - install-minimal-hooks.test.cjs #1755 ("all expected hooks are copied from hooks/dist/ to target", ".js hooks are executable after copy", "manifest contains .js hook entries") failed on any environment with a clean checkout (no pre-existing hooks/dist/): coverage, full test macos-22/macos-24, test ubuntu-24. The failures were masked locally only by a stale hooks/dist/ left from a prior build (build-hooks copies into dist without clearing it). On CI's fresh `npm ci` there is no dist, so the omission surfaced. Fix: add 'gsd-config-reload.js' to HOOKS_TO_COPY so build-hooks stages it into hooks/dist/ alongside the other JS hooks. Verified by removing hooks/dist/ and rerunning the full suite green (0 fail). Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> * fix(#770): make config prototype-pollution beforeEach deterministic on scoped runner Root cause: the #663 and alert-#26 prototype-pollution describe blocks seeded .planning/config.json in beforeEach via a bare runGsdTools('config-ensure-section') whose result was discarded. That command runs in a spawned gsd-tools child; on the scoped CI lane (--test-concurrency=4, config.test.cjs scheduled alongside the heavy install/tarball suites that #770 pulled into the targeted set) the child can be transiently killed under resource pressure (non-zero exit, empty stderr — an OS-level kill, not an app error). The swallowed failure left config.json absent, so the first subtest's readConfig() threw ENOENT opening <tmp>/.planning/config.json. Only 1 of 4 subtests failed, confirming a per-invocation transient, not a deterministic miss; the full suite schedules files differently so config.test.cjs did not collide with those heavy neighbors → passed there. Fix: add ensureConfigReady(tmpDir) which retries config-ensure-section on ANY failure or missing file and throws a clear diagnostic if it still cannot create config.json, then use it in both prototype-pollution beforeEach blocks. Setup is now deterministic under load; the #663/alert-#26 security assertions are unchanged.

The CI scoped (ubuntu-latest/node-22) and windows (windows-latest/node-24) test jobs do NOT run build:hooks before executing tests, so bug-376's prerequisite suite was failing with "hooks/dist not found" on both legs. Add ensureHooksDist() helper (mirrors bug-3357 pattern) that builds hooks/dist on demand in the before() hooks of prerequisite and Suite 3. Also add ensureHooksDist() call to Suite 3's before() so the snapshot step is also hermetic.

Tom Boucher	10f6981743	fix(#685): set windowsHide on all Windows child-process spawns (#688) ... * fix(#685): set windowsHide on all Windows child-process spawns A visible "gsd-core" console window flashed on Windows whenever a gsd-core child process spawned without `windowsHide: true`. The most visible offenders fire on every SessionStart / `/clear` (execNpm's `shell:true` npm view via the update-check worker) and on every Edit/Write/MultiEdit in a worktree (the worktree-path guard's git probe). Add `windowsHide: true` to every external-binary spawn in the runtime source: - hooks/gsd-context-monitor.js (record-session spawn) - hooks/gsd-worktree-path-guard.js (SPAWNOPT) - hooks/gsd-workflow-guard.js (git branch --show-current) - src/shell-command-projection.cts (execGit / execNpm / execTool) - src/check-command-router.cts (git log execFileSync) - src/roadmap-upgrade.cts (git status/rev-parse/reset/clean execSync) gsd-check-update.js already had it (the precedent). probeTty's tty call is POSIX-only and intentionally untouched. Adds a regression test that asserts each site plus a repo-wide completeness guard so a future external-binary spawn that omits windowsHide fails CI. No behavior change off-Windows.

Tom Boucher	463cffd894	chore(#604): rename get-shit-done/ runtime directory to gsd-core/ (#615) ... * chore(#604): rename get-shit-done/ runtime directory to gsd-core/ Renames the installed runtime directory `get-shit-done/` to `gsd-core/` so the on-disk name matches the package (`@opengsd/gsd-core`), repo, and binary (`gsd-tools`). The npm package name and binary are unchanged; npx/npm consumers are unaffected. Mechanical (bulk, ~90% of the diff): - `git mv get-shit-done gsd-core` - Swept path/identifier references across the repo via `perl -pe 's/get-shit-done(?!-\w)/gsd-core/g'`. The negative lookahead preserves the five legitimate slug variants that are NOT the directory: get-shit-done-{OLD,cc,classic,cli,redux} (old package/repo names). - Build/manifest wiring: package.json (bin, files, coverage globs), tsconfig.build.json (outDir), ~86 .gitignore build-output entries, stryker.config.mjs, scan-ignore files, install.js path strings. - Frozen (not rewritten): CHANGELOG.md history; translated docs (README.<locale>.md and docs/{ja-JP,ko-KR,pt-BR,zh-CN}/). New logic (review here): - src/installer-migrations/003-rename-get-shit-done-to-gsd-core.cts: a proper ADR-0008 installer migration. On upgrade it walks the legacy `~/.claude/get-shit-done/` tree, classifies each file via the prior install manifest, and emits remove-managed / backup-and-remove for managed files while PRESERVING unknown user-added files. Symlink-safe (skips a symlinked root and symlinked entries; bounds-checks every path under configDir). The framework rolls back on install failure. Emptied dirs may remain (framework has no recursive dir-removal primitive) — documented. - scripts/lint-legacy-dir-name.cjs: CI regression guard forbidding the bare `get-shit-done` directory token (split token to avoid self-match; case- insensitive; `(?!-\w)` lookahead allows the slug variants; allowlists CHANGELOG, translated docs, and `gsd-allow-legacy-name` marker lines). Wired into the lint-tests CI job. - Restored scripts/lint-package-identity-drift.cjs detection regexes (the mechanical sweep had wrongly rewritten the old-name patterns it exists to detect) and marked them as intentional legacy references. - TDD tests for the migration and the guard; do.md slash-command guard regex tightened so a `/gsd-core/bin` path segment is not mistaken for a command; changeset + docs/installer-migrations.md row added. Breaking: the installed runtime path moves `~/.claude/get-shit-done/` -> `~/.claude/gsd-core/`. Migration 003 removes the stale legacy dir's managed files (preserving user files) on upgrade. Users with custom hooks/configs hardcoding the old path must update them. Closes #604 Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> * fix(#604): unsweep pending changesets + allowlist injection-example docs CI fixes for the rename PR: - Do not sweep pending .changeset/*.md (ephemeral release-note fragments, like CHANGELOG); reverted those body edits so 5 pre-existing malformed fragments (missing type/pr) no longer enter the PR diff and trip docs-lint. Allowlisted .changeset/ in the legacy-name guard accordingly. - Allowlisted TEST-EXAMPLES.md and docs/explanation/security-model.md in prompt-injection-scan.sh: they contain intentional injection examples / security-model prose; the path-reference rewrites are kept. CodeQL alerts on this PR are pre-existing (alert lines unchanged by this PR; none in the new migration/guard) and are out of scope for the rename. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> * fix(#604): resolve CodeQL alerts surfaced on this PR The rename diff touched files carrying pre-existing CodeQL findings; per the no-pre-existing-dismissal rule, fixing every surfaced alert rather than waving them off. All behavior-preserving: - scripts/ci-test-scope.cjs: build the config-path match from string .includes() instead of a RegExp over an arg-derived value (js/regex-injection). - src/profile-output.cts: escape backslashes before pipe-escaping desc/safeName so the table-cell escape is complete (js/incomplete-sanitization). - tests/{bug-2643,bug-2808,docs-parity-live-registry}: two-pass HTML-comment strip so a bare/unclosed `<!--` cannot survive (js/incomplete-multi-character-sanitization). - tests/inline-plan-threshold: drop the no-op `\s`->`\s` identity replace, keep the meaningful POSIX-class conversion (js/identity-replacement). Verified: build:lib green; the touched test files + ci-test-scope + profile-output suites pass; lint:legacy-name clean. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> * fix(#604): correctly resolve remaining CodeQL alerts (regex-injection + sanitization) The prior commit's fixes for two alerts were ineffective: - ci-test-scope.cjs js/regex-injection: the alert is the CLI-arg-derived `file` reaching static regex `.test(file)` calls (not the config rule). Removed ALL regex over file/t — startsWith/includes/=== string checks + an isWindowsHint helper — so there is no regex sink for the tainted value. - js/incomplete-multi-character-sanitization (3 test files): a single `.replace(/<!--...-->/g,'')` can let `<!--` re-form. Replaced with a fixpoint loop (replace until stable) plus a final bare-opener strip. Verified: no regex over file/t remains; ci-test-scope + the 3 test suites pass; lint:legacy-name clean. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> * fix(#604): make ci-test-scope + comment-strippers regex-free to clear CodeQL CodeQL flags the regex PATTERNS syntactically (regex-injection on the --files arg split; incomplete-multi-character-sanitization on the <!--...--> replace), so loop fixes do not satisfy it. Made these paths regex-free: - ci-test-scope.cjs splitFiles: char-by-char separator tokenizer (no /[,\\s]+/). - 3 test files: indexOf/slice HTML-comment stripper (no .replace(/<!--/)). Behavior preserved; ci-test-scope + the 3 suites pass; guard clean. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> * fix(#604): unblock security base64 scan on the large rename diff The security job hit its 10m timeout: base64-scan.sh choked on the binary test fixture tests/feat-3594-parser-property-style.test.cjs (embedded NUL/ non-UTF8 bytes -> thousands of bogus blobs + "ignored null byte" warnings), and the ~800-file rename diff is slow to scan regardless. - scripts/base64-scan.sh: skip binary-by-content files (grep -Iq .) — they can't carry base64-obfuscated *text* and feeding NUL bytes through the per-line scanner is pathologically slow. collect_files already filtered binary *extensions*; this catches binary *content* in text extensions. - .github/workflows/security-scan.yml: raise the security job timeout 10m->30m to accommodate very large diffs (the scan itself is unchanged). Verified locally: scan skips the fixture, 0 "ignored null byte" warnings, 0 findings, exit 0.

Swept the stale references in the merged files to gsd-core so the rename stays consistent and lint:legacy-name passes: - commands/gsd/discuss-phase.md (runtime-launcher shim paths) - src/core.cts (getAgentsDir layout comments) - tests/bug-384-agents-runtime-aware.test.cjs (require path to runtime lib) Verified: guard 0 violations; build green. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> * fix(#604): exclude gsd-core/ path segments from bug-3683 command cross-ref invariant The #614 runtime-launcher shim added to discuss-phase.md references `${_GSD_RUNTIME_ROOT}/gsd-core/bin/...`. bug-3683's REF_PATTERN excluded path-y refs only via lookbehind, but `}` precedes `/gsd-core/` in the shim, so it mis-read the directory path as a dangling `/gsd-core` command ref (same class as the #604 bug-2954 fix). Added a trailing `(?![\w-]*\/)` so `/gsd-<x>/...` path segments are not treated as slash-command references. Verified locally on BOTH platforms before pushing: - mac (node 26) full suite: 0 failures - gsd-test-runner (linux, node22 image) full suite: 0 failures - bug-3683 + bug-2954 pass. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> * fix(#604): lazily resolve findProjectRoot in gsd-tools (harden flaky CI) CI intermittently failed state.test's gsd-tools subprocess with "findProjectRoot is not a function" (flip-flopping across legs; not reproducible on mac full suite, gsd-test linux full suite, test:unit, or state.test x8). findProjectRoot is a re-export from core.cjs (sourced from project-root.cjs); binding it via destructure at module-load can be undefined under a load-ordering edge. Resolve it lazily at call time via a small wrapper so the lookup happens after core.cjs is fully initialized. Verified green on BOTH platforms before pushing: - mac (node 26) full suite: 0 failures - gsd-test-runner (linux, node22) full suite: 0 failures - state.test.cjs: 106/106; gsd-tools loads cleanly.

It documents stub/placeholder RED-FLAG env-var examples (illustrative Stripe test-key / database-URL / API-key placeholders) — not real credentials. Added it to .secretscanignore with the strict annotation, mirroring the existing gsd-core/workflows/plan-phase.md exception.

Rebuild the migration so a stale old install is both harmless and actively removed. - Per-package update cache filename (gsd-update-check-<slug>.json) in the shared ~/.cache/gsd dir, single-sourced via package-identity; writers stamp package_name and readers reject foreign/absent lineage. Multi- runtime visibility preserved (same shared dir + filename across runtimes). - New get-shit-done/bin/lib/legacy-cleanup.cjs seam: detects code-file references to the old package + the legacy fixed-name cache across home runtime dirs; installer auto-cleans on every install; --dry-run previews and mutates nothing. User hooks and dev-preferences are never touched. - update.md cache-clear globs gsd-update-check*.json across ALL supported runtimes (adds cursor/windsurf/augment/trae/qwen/hermes/codebuddy/cline). - Fix worker MODULE_NOT_FOUND post-install (ship managed-hooks-registry.cjs + degrade gracefully) so the per-package cache is always written. - Diataxis how-to: docs/cleanup-get-shit-done-cc.md.
