Tom Boucher	dc3c81e93d	chore(#3212): src/pattern.cts is the sole owner of runtime-value regex construction — Phase 1 (#3416) ... * test(#3412): failing-first suite for the pattern-construction seam Phase 1 of epic #3212 (ADR-3212 §1/§2/§7). Tests only — src/pattern.cts and eslint-rules/no-adhoc-regex-escape.cjs do not exist yet, so both suites fail with MODULE_NOT_FOUND, which is the intended RED. Locks the measured behavior rather than the assumed behavior: RegExp.escape hex-escapes the leading character of nearly every string ("abc" -> "\x61bc"), so the suite asserts match-equivalence against an inlined historical oracle (the implementation being deleted) rather than byte-equivalence of pattern text — 200 seeded fast-check runs plus a fixed corpus, 0 mismatches. Also locks the latent character-class range bug this phase fixes as a side effect: a hyphen-bearing value interpolated into [...] currently forms a real range and matches an unintended character; post-migration it must not. * chore(#3412): src/pattern.cts owns runtime-value regex construction Phase 1 of epic #3212 (ADR-3212 §1/§2/§6/§7). Adds the pattern seam delegating to the built-in RegExp.escape, deletes every hand-rolled copy, and raises the Node floor to the Active LTS line. The census was low, three times over. ADR-3212 counted 10 copies; a graph query found 12; the new lint rule — once live — found 27 more. The difference is that the census counted named helper FUNCTIONS while the rule counts the escape SHAPE, so inline .replace(<class>, '\$&') copies were never in scope. ADR §1's actual requirement is that no module outside the seam escapes a value for regex use, so all of them are, and CLAUDE.md's no-defer rule makes them this change's work. Fourth consecutive epic here whose copy count was low — the argument for ADR-3180 Amendment 3's "state N found by the guard" rule. Also corrected mid-implementation: the survey reported phase-id.cts's escapeRegex had 0 external importers. It had 8 production importers, making its removal a public-surface change to an ADR-2121-owned module and requiring an update to that ADR's locked-surface test. Blast radius revised Medium-High -> High. RegExp.escape is match-equivalent but NOT text-equivalent: it hex-escapes the leading char of nearly every string ("abc" -> "\x61bc"). Equivalence is proven by a seeded fast-check property test against the deleted implementation as oracle. It also fixes a latent bug: a hyphen-bearing value interpolated into a character class previously formed a real range and matched an unintended character. Node floor 22 -> 24 (RegExp.escape is Node 24+), across engines, .nvmrc, package-lock, 9 CI matrix entries, and 5 docs. The aggregate `required-tests` context is unchanged and no job was added or removed, so branch protection cannot be orphaned by the dropped lanes. Enforced by eslint-rules/no-adhoc-regex-escape.cjs (shape-matched, with structural provenance for reviewed pattern-fragment constants rather than a name heuristic) plus a whole-tree companion guard covering the directories ESLint's globs miss. * fix(#3412): close the _SOURCE guard evasion, correct two false claims Three findings from the orthogonal review pass, all fixed. 1. The ESLint rule's `_SOURCE` provenance fallback was pure identifier- name matching with no binding check, so `new RegExp(userInput_SOURCE)` — a function parameter — sailed past the guard. That is the same rename-evasion class issue #3410 documents, reopened by the very fallback meant to complement the structural check. Now bound to the identifier's actual binding kind: import, require-derived const, or module-scope const; parameters, `let`/`var`, and unresolvable bindings fail closed. Four RuleTester cases cover the evasion and prove the legitimate cross-module case still passes. 2. src/pattern.cts's own header carried the stale pre-correction counts (12 copies / 17 call sites) while CONTEXT.md and the design doc carried the corrected ones (~39 / ~44) — a self-contradiction inside the PR whose entire purpose is deleting divergent copies. Rewritten, preserving the durable lesson: a named-function census cannot see inline copies; only a shape-matching guard can. 3. The claim that all deleted copies threw TypeError on non-string was false. phase-id.cts's copy — the one with 8 external importers — did String(value).replace(...) and never threw. The seam's locked signature does not coerce, so this is a real, now-disclosed behavior change rather than the pure preservation the tests asserted. Audited all 32 invocations across the 8 importers and 6 in-file callers: every one is safe by construction (upstream truthy guard or a string-producing derivation), verified by runtime probe against the compiled modules rather than by TS compilation, which cannot see a runtime undefined. Corrected the false claim in both the test comment and the design doc, and added it to Known limits. * docs(#3412): add Changed changeset for the Node 24 floor The only user-visible break in this phase. The escape-behavior change is internal and match-equivalent, so it carries no user-facing note. * fix(#3412): resolve the seam's require graph in script fixtures and packaging Checkpoint 2 came back red with 90 failures on the node24 lane. Three distinct defects, all introduced by routing scripts/ through the new pattern seam, none reproducible by any local gate: 1. ~82 failures — tests/adr-index-gate.test.cjs and tests/removed-but-needed-lint.test.cjs copy a scripts/*.cjs into an mkdtemp fixture and spawn it there (necessary: those scripts resolve their scan root from __dirname/.., so running the real script would scan the real repo). Each harness hand-listed the dependencies to copy alongside. Adding require('../gsd-core/bin/lib/pattern.cjs') to gen-adr-index.cjs made both lists silently incomplete -> MODULE_NOT_FOUND, plus 17 downstream 'did not emit parseable JSON' failures from the same crash. Fixed as a class, not an instance: new tests/helpers/copy-script- fixture.cjs walks a script's transitive static relative-require graph and copies it, so dependencies are derived and never re-declared. It throws (naming the unbuilt artifact) instead of letting the child die with a bare MODULE_NOT_FOUND. Verified for all four seam-consuming scripts: gen-adr-index, lint-removed-but-needed, gen-loop-host- contract, sync-runtime-launcher. 2. 2 failures — scripts/ ships wholesale but eslint-rules/ does not, so the new scripts/lint-no-adhoc-regex-escape.cjs would be MODULE_NOT_FOUND in a published install (#2858 guard). Excluded from the tarball, matching the existing precedent for gen-emitted- baseline.cjs, which is excluded for the identical reason, and locked with a test modeled on that one. Confirmed against a real npm pack: 890 files, 0 from eslint-rules/, and gsd-core/bin/lib/pattern.cjs present (so the other four scripts' requires are legitimate). 3. 6 failures — tests/phase-id.test.cjs asserted the literal escaped source text ('0*29', 'PROJ-42'). RegExp.escape is match-equivalent to the retired hand-rolled escaper but NOT text-equivalent: it hex- escapes the leading character and all hyphens ('0*\x329', '\x50ROJ\x2d42'). Verified NOT a behavior change — 576 match decisions across all three real interpolation prefixes, zero divergence. Those tests now compile each source into the same heading regex src/roadmap.cts's searchPhaseInContent builds and assert what matches and what does not, including the 'i'-flag canonicalization the hex escape has to preserve. Re-pinning the new literals would have rebuilt the same brittleness one layer down. Adds a test for the property the escape exists for: a dot in '1.2' must not act as a wildcard. Also shares one definition of 'a require' between the packaging guard and the fixture copier, so the two cannot disagree about what they scan. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * fix(#3412): refuse to copy a fixture dependency outside the fixture root copyScriptWithDeps resolved each relative require and joined the repo-relative result onto fixtureRoot. A require resolving OUTSIDE the repo yields a '../'-prefixed relative path, so path.join climbed out of the fixture and wrote into the surrounding temp dir (verified: repoRoot=/repo + depAbs=/etc/passwd wrote /tmp/etc/passwd). No script in the tree does this today, so this closes an available escape rather than an active one. Refuses via the existing unresolved- require path so the failure names the offending specifier. Covered by a negative proof that the guard fires and that nothing lands outside the fixture. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * fix(#3412): parse requires instead of pattern-matching them; restore the foreign-prefix contract Applies all findings from the second orthogonal review round, re-run because real code changed after round 1. HIGH (security) — extractRequires stripped BLOCK comments before LINE comments, so a '//' comment containing '/*' opened a phantom block comment, and a '//' inside a string literal truncated the line. Both hid real requires: 'const u="http://x"; require("./real.cjs")' returned [], and four real requires in gsd-core/bin/gsd-tools.cjs were invisible. Replaced with a real AST parse via espree. This is ADR-3212's own Decision 4 — tokenizer-first for stateful grammars — applied to the case it describes; comment/string/regex nesting is exactly such a grammar, which is why the regex version was wrong. The function was moved byte-identical out of the #2858 packaging guard, so the bug PRE-DATES this branch and has been a live blind spot there: a shipped script could have required an unshipped path undetected. Fixing it makes that guard strictly stronger than on next. espree is promoted from a transitive eslint dependency to an explicit devDependency rather than relying on hoisting. The script parse attempt sets ecmaFeatures.globalReturn because Node wraps CommonJS bodies in a function, making a top-level return legal — scripts/check-coverage-gate .cjs relies on it, and without the flag the guard throws on a file it is supposed to scan. Verified 0 unparseable across all 324 .cjs/.js under scripts/, bin/, and gsd-core/bin/, and 0 new violations against a real npm pack, so the exact extractor does not newly fail the guard. MEDIUM (security) — the repo-containment check guarded dependencies but not the entry path. One escapesContainment predicate now guards both. LOW (security) — containment was lexical while fs follows symlinks, and a directory symlink could mint a fresh dedupe key per level. realpath now resolves both repoRoot and each dependency before the decision, and the realpath-derived path is the dedupe key. Destination layout still uses the original repo-relative path, so copied trees are unchanged. MAJOR (standards) — the round-1 behavioral rewrite of phase-id tests lost the foreign-prefix contract: every assertion was satisfied by an impl returning [A-Z]+\x2d42, i.e. ANY project code — the exact #3599 bug class the exact-source prevents. The literal assertions it replaced were catching this. Now asserts the compiled regex REJECTS a different prefix with the same number. MAJOR (standards) — the test hand-duplicated production's heading regex with no parity guard (CLAUDE.md's 'Generative Fix Divergence'). Removed the parallel surface instead of policing it: src/roadmap.cts exports buildPhaseHeadingRegex, searchPhaseInContent calls it, the test imports it. Byte-identical .source and .flags verified for both escaped forms. MINOR — '..foo' no longer false-flagged as an escape; the inverted spurious-vs-missing doc claim corrected; the dead allow-test-rule header removed. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * chore(#3412): backfill changeset pr number to 3416 * fix(#3412): make the escape guard's own regex linear, reword an injection-scan collision Two CI failures on PR #3416, both in code this branch added. CodeQL js/redos (high) — REPLACE_CALL_RE's outer alternation let a bracket run be consumed EITHER by the character-class branch OR one character at a time by the trailing catch-all, so a failing match explored both parses of every pair. Measured on the real regex: n=26 -> 204ms, n=28 -> 791ms, n=30 -> 3475ms, a clean 2^n. This script scans repo source, so a file with a long bracket run after '.replace(/' would hang CI outright — a guard against undisciplined pattern construction was itself the worst pattern in the diff. Fixed the way ADR-3212 already prescribes: the catch-all branch now excludes '[' and ']' so a bracket can only be consumed by the class branch (this is what makes it linear), and every quantifier is bounded (the locked bounded-quantifiers decision) as a second line of defense. Now 0ms at n=2000. Disclosed coverage tradeoff, recorded at the constant: a regex literal with a BARE unescaped ']' outside a class is no longer matched by this backstop. No census shape has that form, and the AST rule remains the primary detector. Verified the guard did not go blind doing it: a real census-shape violation is still reported, and an allow-adhoc-regex-escape suppression comment is still honored. Regression test drives the exported findViolations on a 2000-repetition adversarial input and asserts the RESULT. It makes no wall-clock assertion — elapsed-time tests are forbidden — so a regression surfaces as a harness timeout, which is the correct signal. Prompt injection scan — 'must not act as a regex wildcard' in a test comment matched the scanner's jailbreak pattern act\s+as\s+(a|an|if| my). Reworded to 'behave as'. Deliberately NOT allowlisted: silencing a whole test file over one phrase would blunt the scanner permanently, and the comment has nothing to do with injection. Neither failure was reachable from the remote runner — CodeQL and the injection scan are not in that matrix, so the sha it passed was green and still wrong.

0xdhx	652b99b71b	test(#2665): reversion guards for all three round-4 fixes ... None of the round-4 fixes had a test that fails on reversion: re-shipping the test-instrumentation chain passes #2858 (everything ships, so every require resolves), dropping the strict env from test.yml demotes the guard to report-only with nothing red, and the skillsHome derivation tests are enumeration-relative over declarations that are all empty today. One guard each, every one negative-controlled against its reverted fix (fails pre-fix, passes post-fix): - packaging-shipped-scripts-require-only-shipped.test.cjs asserts the four chain files are absent from the npm pack file list (reuses the tarball set the #2858 gate already resolves — no second npm pack). - live-config-guard.test.cjs asserts all three test jobs wire GSD_STRICT_LIVE_CONFIG_GUARD, matching the WHOLE expression anchored — a prefix match accepted both a Windows-silently-strict tail and a malformed one. - helpers-process-isolation.test.cjs cold-requires helpers.cjs in a child with sentinel skillsHome env vars injected into both enumerations, so the walk itself is under test rather than today's empty declarations.	2026-08-08 05:50:49 -05:00
Tom Boucher	628648d63a	chore(#2931): cap emitted per-runtime bytes and single-source windsurf (#2984) ... * fix(#2931): preserve protected regions and cap emitted per-runtime bytes Route every runtime brand swap through applyClaudeCodeBrandSwap so "Claude Code" survives verbatim inside <runtime_compatibility> regions (#2284b). The fix existed only in bin/install.js's local copies; the src/*.cts exports still used a naive replace, so binding install.js to the single source -- as this phase does for the Windsurf family -- would have silently regressed those runtimes. A table-driven parity guard now covers all nine brand-swapping converters. De-duplicate the Windsurf converter family: delete the six local copies in bin/install.js and bind the four exported ones by reference, guarded by reference-identity assertions (the ADR-1508/#1675 pattern). The two unexported helpers and an unused tool table go with them. Replace the Windsurf 12,000-byte throw with description truncation, matching the bound its sibling skill converter already applied. The throw could only fire on an ~11.7 KB frontmatter description: the largest emitted workflow is 311 bytes. Truncation makes the cap unreachable by construction and leaves 12,000 in exactly one place, eliminating the dual-surface duplication rather than testing for it. Add the emitted-byte cap gate: buildEmittedSizes captures LF- and <HOME>-normalized bytes from the walk buildParityManifest already performs, and evaluateEmittedCaps asserts them against a per-runtime cap table with dead-rule detection. buildParityManifest's return shape is deliberately unchanged -- diffEmitted compares its values with ===, so making them objects would report all 8,529 emitted paths as moved. A regression test pins the values as strings. Add a deterministic trim-safety gate over composeWithinBudget's omitted/shrunk/floored/isolatePrefix metadata, with an anti-vacuity rule, replacing the model-graded eval gate the issue described. * docs(#2931): correct ADR-1671 windsurf premise and trim-safety contract * fix(#2931): bound the windsurf command name and single-source the brand swap Review findings from the orthogonal passes, all fixed inline. The claim that removing the 12,000-byte throw left total emission "bounded by construction" was false. The #1615 regex constrains the character class but not the length, and commandName is interpolated three times into the emitted workflow: a 20,000-character name emitted 60,162 bytes silently. Add WINDSURF_COMMAND_NAME_MAX=128 as a separate, clearly-labelled size control that THROWS -- commandName is the @-ref path target, so truncating it would point the workflow at a file that does not exist (DEFECT.WORKFLOW-DELEGATION-TARGET-NOT-INSTALLED). The #1615 security regex is untouched and still runs first. 128 is generous: the longest shipped name is gsd-plan-review-convergence at 27. Harmonize convertClaudeCommandToWindsurfSkill onto the code-point-safe truncation helper. It still used a UTF-16 slice(0,177) -- the exact surrogate-splitting bug the helper was written to avoid, in the very sibling the helper's comment cites as its model. Bounds are unchanged, so output is byte-identical for every shipped command (descriptions max out at 99 chars). Export applyClaudeCodeBrandSwap and bind it in bin/install.js, deleting the local copy. Adding it to the .cts left two unlinked implementations of identical logic -- the drift class this change exists to remove. Verified byte-identical across eight fixtures and five sequential calls before merging, and guarded by a reference-identity assertion. Convert three try/finally test bodies to t.after (CONTRIBUTING.md:344), add fast-check property coverage for the trim-safety contract, and use fc.pre instead of a bare return in a property callback. * test(#2931): fix three test-authoring bugs the remote matrix caught The remote runner returned 8 unique failures on 6f15cdeb8. All three causes were in the test files, not the modules under test -- local harnesses exercise the modules directly, so nothing executed the test bodies until the matrix did. `{ __proto__: [...] }` in an object literal sets the prototype instead of an own key, so the JSON round-trip erased it and the cap table never saw a reserved runtime key. The production rejection was already correct; the test could not reach it. Use a computed key. Two cap fixtures tripped orthogonal error paths rather than the paths they name: one declared windsurf in the cap table but omitted it from sizes (UNKNOWN_RUNTIME), the other left the sole windsurf pattern matching nothing (a genuine dead rule). Both now include a compliant artifact so the intended branch is what is asserted. The dead-rule and unknown-runtime contracts are deliberate and unchanged. `const { root } = makeSyntheticConfig({ ... `${root}` })` referenced `root` from inside its own initializer -- a temporal dead zone error. makeSyntheticConfig now optionally takes a (root) => files factory. Also raise the npm pack --dry-run bound 60s -> 120s in the shipped- scripts packaging test. That failure is NOT from this branch: the file is byte-identical to next, a fresh tsc measures 1.98s there vs 2.14s here, and the run recorded 60,637ms against a 60,000ms bound -- a timeout under 28,948-test parallel contention, not a slowdown. Fixed rather than deferred because a bound that tight is fragile regardless of which branch trips it. * chore(#2931): backfill changeset pr number to 2984 --------- Co-authored-by: sim <sim@local>	2026-08-01 16:00:14 -04:00
Tom Boucher	d3305fc3a5	fix(#2858): exclude gen-emitted-baseline.cjs from npm tarball + class-extinction guard (#2968) ... * test(#2858): add class-extinction guard for shipped-script require boundary Every shipped scripts/**/*.cjs must be require-able using only shipped paths. The guard resolves the tarball file list via npm pack --dry-run --json (not a hardcoded list) and statically checks each require() call against the shipped set. A script requiring ../tests/** (which does not ship) is a violation. * fix(#2858): exclude gen-emitted-baseline.cjs from the npm tarball scripts/gen-emitted-baseline.cjs is repo-only CI tooling (CI workflows + test fixtures spawn it from a checkout). It requires three modules from tests/, which does not ship — so in a published install it is MODULE_NOT_FOUND at load time. Add a targeted files[] negation (!scripts/gen-emitted-baseline.cjs) so the script stays in the repo for CI use but does not ship. Other scripts that ship and are required by bin/install.js (build-hooks.js, fix-slash-commands.cjs, gen-capability-registry.cjs) are unaffected. The class-extinction guard test in tests/packaging-shipped-scripts-require-only-shipped.test.cjs ensures no shipped script can require outside the shipped tree going forward. * test(#2858): widen guard to .js + strip block comments (review fixes) Two findings from isolated adversarial review: 1. MAJOR: the guard only checked .cjs files, but scripts/build-hooks.js ships and is required by bin/install.js — a .js file with a broken require would bypass the guard. Widened filter to /\.(cjs|js)$/. 2. MODERATE: the static parser could false-positive on require() calls inside /* */ block comments or inline // comments. Now strips both before matching. * chore(#2858): add changeset fragment * chore(#2858): backfill changeset PR number 2968 * fix(#2858): add issue ref to allow-test-rule exemption (ADR-456) CI lint-tests caught: the allow-test-rule comment needs a 'see #NNN' ref per ADR-456. Added '(see #2858)' to the integration-test-input exemption. --------- Co-authored-by: sim <sim@local>	2026-08-01 09:29:15 -04:00
