Three families currently encode failure as success, and this commit pins each one RED before the fix lands. Measured on this tree, 2026-08-26: gsd-tools generate-slug "test" --pick nonexistent -> empty stdout, exit 0 (#3365) gsd-tools audit-open --pick nonexistent_field -> dumps the entire human-readable audit report, exit 0 gsd-tools generate-slug "Hello World" --raw --pick bogus -> prints "hello-world", another field's value, exit 0 gsd-tools query state.planned-phase 3 (positional, no --phase) -> exit 0; STATE.md's "Phase: 2 of 5 (Widget Support)" is overwritten to "Phase: null - READY TO EXECUTE" and the frontmatter gains a corrupted current_phase_name (#3358) tests/pick-flag.test.cjs:27 previously asserted the #3365 defect as the contract ("returns empty string for missing field", success === true). That assertion is replaced by the required behavior rather than deleted. The new parseNamedArgs block calls the spec-object signature that does not exist yet, so it fails today by construction. The 11 existing behavior-lock tests are left untouched here; they are corrected in the implementation commit. C1/C4 assert at the consumer's output - STATE.md's bytes - per ADR-3180 Decision 4(b). A unit assertion on the parser would have passed throughout this defect's life.

Absence, emptiness and failure stop being interchangeable ways to say "I could not answer". parseNamedArgs (src/command-arg-projection.cts) Takes a spec object with a REQUIRED `positionals: number | 'rest'` and returns the hub's Result shape instead of a bare Record. Declaring the positional arity is what makes #3358's call site unrepresentable rather than merely detectable: an unrecognized flag or a token past the declared boundary is now InvalidArgs, naming the offending token and listing the accepted flags. The legacy positional-array call shape throws a TypeError — an internal invariant violation per ADR-3473 Decision 2, so a stale hand-written .cjs call site fails loudly instead of destructuring undefined off a Result. parseNamedArgsOrExit projects a failure onto the caller's error(); it is a projection over the one parser, not a second parser. Measured before, against a STATE.md with a populated phase-2 block: query state.planned-phase 3 (positional, no --phase) -> exit 0; "Phase: 2 of 5 (Widget Support)" overwritten to "Phase: null - READY TO EXECUTE", frontmatter gains a corrupted current_phase_name After: exit 1, `unexpected positional argument "3"`, STATE.md byte-identical. The flag form is unchanged and still updates STATE.md. --pick <field> (gsd-core/bin/gsd-tools.cjs) extractField returns {found,value}, and the pick block no longer shares one catch between "output was not JSON" and "field was absent". An absent field exits 1 with pick_field_absent, naming the field and the keys that do exist; non-JSON output exits 1 with pick_output_not_json instead of dumping the command's entire output. A field that is PRESENT with value null, '', 0 or false still prints at exit 0 — that is an answer, not a failure, and it is what keeps `--pick count` printing 0 on a fresh project. Measured before: `audit-open --pick nonexistent_field` printed the whole human-readable audit report at exit 0, and `generate-slug X --raw --pick bogus` printed "hello-world" — a different field's value, confidently, at exit 0. ADR-3409 Decision 7 explicitly deferred this contract fix to #3473; this is it. The sub-issue's "returns 0 when the count is zero OR absent" wording is superseded by the ADR rule it implements: zero prints 0, absence exits non-zero. Defaulting absence to 0 would demote "could not answer" to "the answer is zero" — the hazard docs/how-to/resolve-unreachable-guard-findings.md already warns against. Guard ledger (ADR-3473 Decision 6) scripts/lint-unreachable-guard-drift.cjs Detector A is RETIRED. Its premise — that a `--pick ... || echo` arm can never fire — is now false, so the shape it forbade is the correct idiom and keeping it would forbid the fix. Detector B (glob-consuming cat/ls, a nullglob mechanism this change does not touch) is retained in full, as are the shared scanner, the escape-marker parser and the baseline. Net: -1 detector, 0 added. The file is not deleted. Call-site audit 45 prompt-layer --pick invocations, every one a plain X=$(...) assignment — none in an if test, && chain, or a pipeline whose status is consumed, and no shell block in workflows/commands/agents/references sets -e. Of the 13 (command, field) pairs the prompt layer reads, 10 are always present; the 3 sometimes-absent ones each sit behind a prior found/existence check. No ADR-3409-class "field the command never produces" remains. Design: .gsd/phase/feat-3884-failure-is-a-value/40-design.md Test matrix: .gsd/phase/feat-3884-failure-is-a-value/50-test-matrix.md Refs #3884 Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * fix(#3884): escape untrusted tokens in diagnostics, and cover five unpinned rows Two review findings, both fixed here rather than recorded as limits. 1. A newline in an untrusted token forged a second stderr line. Before, plain-text mode: $ gsd-tools query state.planned-phase $'foo\nError: forged second line' Error: unexpected positional argument "foo Error: forged second line" After: Error: unexpected positional argument "foo\nError: forged second line" --json-errors mode was never affected — io.error runs that payload through JSON.stringify. Plain-text mode writes 'Error: ' + message verbatim, and the three new InvalidArgs reasons plus the two new --pick diagnostics all interpolate a token that comes straight from argv. Fixed with ONE shared helper, formatDiagnosticToken (src/io.cts), applied at every interpolation site — not a copy per site. It is deliberately NOT applied inside error() itself: several callers in this tree emit intentional multi-line diagnostics, and escaping newlines there would mangle them. The available-top-level-keys list needed the same treatment for a reason the review did not anticipate: `frontmatter get <file>` reads an ARBITRARY user document and echoes that document's own keys into the diagnostic. Verified reachable — a frontmatter key containing a newline reaches the key list — so formatKeyForDiagnosticList is guarding a live path, not a hypothetical one. Ordinary keys still render plain and unquoted; a fix that merely dropped the key would also have passed a "one line" assertion, so the test pins the escaped key's presence too. 2. Five behavior-table rows were implemented but nothing pinned them: B7 a dotted path that dies partway B9 bracket syntax on a non-array B10 a negative array index, in and out of range B14 a JSON root that is not an object B17 an @file: payload over 50KB B17 is the load-bearing one. output() writes @file:<path> instead of inline JSON past 50000 characters, and --pick resolves that BEFORE parsing; with no test, a future reordering of those two steps turns every large result into a false pick_output_not_json. The fixture seeds 1200 phase directories and measures the payload at 62474 characters, asserting the spill actually happened rather than assuming it. Refs #3884 Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * fix(#3884): correct the strict-argv surface against a full verification run The first full run came back with 90 failures across 12 files, none in the new tests. They were the argv surface telling me what it actually is. Ten root causes; each classified before anything was changed. I over-implemented, and that is reverted. ADR-3473 §8.4 says parseNamedArgs rejects "unrecognized and positional tokens". It says nothing about a value flag whose value is missing. Making that an error was my design decision, not the rule, and it broke a deliberately recorded contract: `--prd` with no value resolving to null (tests/init.test.cjs emptyPrdValueIsFalsyAndTreatedAsAbsent, row B5; tests/section-manifest-init-facts.test.cjs "flag-shaped value"). The "requires a value" branch is deleted outright rather than kept behind an option — an unused strictness mode is speculative generality. Unknown-flag and unexpected-positional rejection, which is what §8.4 actually mandates, is unchanged. --wave needed a third flag kind the original design did not anticipate. `--wave N` is documented (commands/gsd/execute-phase.md:4,48) and the shipped workflow reconstructs and passes it (execute-phase.md:84), while #2932 records token-PRESENCE semantics: the CLI cares only that the flag appeared, and the value belongs to the workflow layer. That is neither a boolean flag nor a value flag, so `optionalValueFlags` now exists — presence-only in `data`, and the validation cursor consumes a following non-flag token so it is not reported as a stray positional. Every other declared boolean flag was checked against every argument-hint and prose usage in commands/, workflows/, agents/ and docs/; `--wave` is the only one of this shape. Five tests were pinning forms that never worked. tests/adr857-core-without-capabilities.test.cjs passed `init plan-phase --phase 01-stub`, but the documented form is positional (docs/CLI-TOOLS.md:776) and the handler reads args[2] — which for that form is the literal string "--phase". Measured on the pre-fix build against a real .planning/phases/01-stub/ directory: init plan-phase 01-stub -> phase_found=true init plan-phase --phase 01-stub -> phase_found=false The test asserted only exit 0 and key presence, so it had been green while proving nothing about phase resolution. Corrected to the documented form and strengthened to assert phase_found === true. Same class in state.test.cjs (`--plan-count`, a flag that does not exist; the real one is `--plans`), milestone-archive.test.cjs (`init new-milestone --json`, silently ignored), and concurrency-safety.test.cjs (a bare positional field name whose OR-assertion passed because a whole-document dump happens to contain the substring it looked for). Six handlers had no argv validation at all — the same #3358 shape this phase exists to close, found while fixing the rest: init verify-work / phase-op / review / todos / remove-workspace read args[2] with nothing checking the rest, and validate health read --repair/--backfill through a bare args.includes() scan that bypassed the parser entirely. All now go through the seam, so the flag has one owner. tests/init-debug.test.cjs rows C4/C5 asserted that an unrecognized flag must NOT fail. That is the behavior §8.4 removes, and Decision 8 says a caller's local expectation does not override §8, so they are inverted and renamed — a test still called "ignores an unrecognized flag" while asserting rejection would be its own defect. Row C6's point is its PWNED canary; that assertion is kept verbatim and only its exit-status expectation changed, because the hostile token is now rejected rather than absorbed. The blast-radius estimate in 40-design.md is corrected rather than quietly left wrong. get_impact reported MEDIUM / 8 symbols upstream, and that was accurate for what the graph can see — parseNamedArgs's callers. It cannot see that those callers' handlers accept argv shapes wider than the code reading args[2] suggests, which is where the real surface was. Refs #3884 Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * fix(#3884): withdraw the validate-health tightening, finish the A2/A3 revert Second full run: 46 failures, down from 90. Four causes, two of them mine. Reverted `validate health` entirely — it was scope creep, and it broke a real flag. ~30 of the 46 read `unknown flag "--json"; accepted: --repair, --backfill`. The previous commit routed `validate health` through the parser on the reasoning that a flag should have one owner. That was wrong twice over: §8.4 names parseNamedArgs and count queries, and `validate health` was never a parseNamedArgs call site — it read its flags, just not through the parser, so it had no silent-drop defect to fix. Tightening it omitted `--json`, which the health-diagnostic suites use heavily. The handler is now byte-for-behaviour back to its pre-branch form. `validate context` stays converted: it genuinely was a call site, and its `--json` is now declared rather than read by a second `args.includes` scan. The five handlers that had NO validation at all — init verify-work / phase-op / review / todos / remove-workspace — stay fixed. Those read args[2] with nothing checking the rest, which is the #3358 shape this phase owns. Finished the A2/A3 revert. Three tests still encoded the deleted "a value flag with a missing value is an error" rule, including one added by the previous commit for that rule. All three now assert the reverted null contract, and the ones whose titles said "rejected" are renamed — a test named for a contract it no longer asserts is its own defect. `--wave=` and `--wave --weird` are correctly rejected. Neither is documented in commands/gsd/execute-phase.md, gsd-core/workflows/execute-phase.md or docs/, and neither is emitted by the shipped prompt layer, so both are unrecognized tokens that §8.4 mandates rejecting. `doesNotConsumeFollowingFlagAsWaveValue` keeps the property it exists for — asserted directly now, at the parser, that `--wave` does not swallow a following flag as its value — and only its exit-status expectation changed. A contradiction inside this branch, surfaced by the audit and resolved the safe way. Two pre-existing #3573 tests call `state begin-phase '2'` and `state planned-phase '2'` with a bare positional, relying on the old permissive parser to ignore it. This branch's own #3358 regression test requires that exact argv to be REJECTED. The two are mutually exclusive. Widening the router to accept a bare positional — mirroring complete-phase — would have silently re-opened #3358, and was verified to do exactly that: with the widened router, `query state.planned-phase 3` returned exit 0 and wrote current_phase_name again. It is reverted. docs/CLI-TOOLS.md:116 and docs/COMMANDS.md:2192 document only the `--phase N` form for both verbs, so the two #3573 tests move to it. Their assertions were never about the call shape — only that total_phases survives the resync — and both still pass. complete-phase is untouched: its bare positional IS documented, and it keeps the dynamic boundary and the negative-space note that record why. The audit that produced this is in the PR body: for every handler whose declaration changed, the flags it reads anywhere in its body, the flags the shipped surface documents, and the shapes the suite passes, compared. The `--json` miss was a pattern, not an accident — declaring a handler's flags from its parseNamedArgs call alone misses whatever it reads elsewhere.

Tom Boucher	85ed50cc4f	test(#1972): consolidate 94 command/module regression tests into subject suites ... Fold 94 issue-named command/module regression files into the canonical test file that owns each subject-under-test, across 52 existing suites (state, config, frontmatter, roadmap-parser, capability-registry, shell-command-projection-dispatch, plan-phase-drift-guard, health-validation, runtime-converters, commands, etc.). Verbatim block-scoped describe wrappers; 881 subtests conserved 1:1. No new test files. Host-env pre-check (per B2): the only GSD_WORKSTREAM/GSD_PROJECT-touching destinations (intel, planning-workspace) clear those vars hermetically, so folded CLI tests are safe. Regenerates regression-name allowlist (222->162), ratchets file-count allowlist across 8 buckets (validate entry removed after dropping <=2), makes 34 relocated allow-test-rule exemptions issue-ref-compliant (ADR-456; prunes 34 stale ids). Repoints CONTEXT.md + ADR-0002/443/1235/3524 test-file references. lint:ci green. Part of epic #1969. Closes #1972. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>	2026-07-03 08:59:23 -04:00
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. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> * fix(#604): sweep get-shit-done refs introduced by merging next The branch was updated with next (#614/#384/#618 etc.), which reference the get-shit-done/ dir (still named that on next). 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. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> * fix(#604): allowlist verification-patterns.md placeholder examples in secret scan The rename git-mv'd references/verification-patterns.md into gsd-core/, pulling it into the secret-scan diff. 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. Verified locally: secret-scan-lint --strict OK; secret-scan --diff origin/next exits 0 with 0 findings.

Tom Boucher	d77170a25d	perf(#312): index argv once in parseNamedArgs (#392) ... parseNamedArgs re-scanned argv with indexOf/includes once per flag — O(flags * argv) — on the command-dispatch hot path (24 call sites across gsd-tools + init/state/validate routers). Build a first-index Map of argv tokens in a single pass and use it for the flag lookups, dropping it to O(argv + flags). Semantics are identical: firstIndex.get(t)??-1 === indexOf(t), firstIndex.has(t) === includes(t); first-occurrence-wins and the value-token rejection are preserved. Adds the first behavior-lock tests for the module. Co-authored-by: Claude Opus 4.7 (1M context) <noreply@anthropic.com>	2026-05-27 20:21:36 -04:00
