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.

Tom Boucher	9faacc0c15	test(#3148): bound the long tail and delete the unbounded-spawn allowlist (#3192) ... * test(#3148): bound the long tail and delete the allowlist Migrates the final 170 unbounded sync spawn sites across 49 files, then removes the allowlist entirely. local/no-unbounded-spawn now runs with no exemption surface across tests/**: there is no file to add a name to. drift-detection's throw-native git() helper routes to gitOrThrow -- bare runGit would have taken 16 call sites quiet on failure. commands.test.cjs has two independently-scoped runGsdTools/runCli helpers, one already bounded and one not; they are kept distinct rather than unified, the same trap as the two same-named git() helpers in Wave 1. runNpm's bound was erasable. Its options spread callerOptions after the defaults, so an explicit timeout:undefined silently dropped the 180000ms bound -- the rule flagged it and was right; it was not a false positive. Fixed by destructuring with a default, with a test that fails when the default is removed. Two sites stay on a raw spawn with an explicit timeout because the seam cannot express them: one needs shell:true for npm.cmd on Windows, one redirects stdout to a real fd. Both are the rule's own documented second option, not an escape from it. Closure verified rather than asserted: the derivation scan reports 0 unbounded spawn helpers and 0 unbounded direct git call sites, and a temporary file carrying an unbounded spawn still errors with the allowlist gone. Closes #3064. * test(#3148): close a hole in the guard's own eslint-disable ban The ban listed only the top level of tests/, so it was blind to 37 .cjs files under tests/helpers, qa, observability, fixtures and dispatch. With the allowlist deleted this test is the sole remaining way to detect someone silencing the rule inline, so the gap was load-bearing: a nested file could carry an unbounded spawn plus an eslint-disable and pass everything. Proven before and after. A probe planted under tests/helpers with both was invisible to the guard and clean under eslint; after making the listing recursive the guard fails on it. The scanned set goes from 771 files to 808. Pre-existing since the guard shipped, but this wave is what promoted it to sole defense, so it is fixed here rather than filed. Also converts the last hand-rolled throw check to throwIfFailed and the last re-derived legacy shape to compose toLegacyResult, which makes the epic's none-remain claim true rather than nearly true. toLegacyResult itself is not widened -- eight callers depend on its shape and one consumer does not justify changing a shared contract. * fix(#3148): correct seam incoherence at the bound and a slow review-lane error path Two real failures from the remote runner, both fixed at the cause. The seam could return outcome TIMED_OUT together with exitCode 0. At the exact bound spawnSync reports ETIMEDOUT while the child has already exited with a real status, and toSeamResult classified on the error code while passing status straight through -- an incoherent pair its own boundary test was written to catch, and did. A status that is not null is direct evidence the child exited on its own, so it now decides the outcome before the error-code branches run. process-seam.cjs was deliberately untouched by every earlier wave; this is a defect in the module itself, kept surgical, with a unit test that fails against the old logic. review-lane with an unknown subcommand fell through to its usage error only after loading the capability registry and building a per-lane plan, which spawns one child process per lane -- up to twelve. The error path took ~1288ms instead of ~119ms, and under bench load it outran a caller's spawn timeout and was killed before writing anything, which is the empty stdout and stderr CI saw. It now fails fast before any of that work begins. This is the epic's first production change. It is user-facing, so it carries a changeset rather than a no-changelog label. * test(#3148): replace a real-race timeout test with a deterministic one E9 raced git rev-parse against a 1ms bound and assumed git always lost. On a warm container git finishes first, spawnSync returns status 0 with no error at all, the seam correctly classifies EXITED, and gitOrThrow correctly does not throw -- so the test failed on both lanes. A probe confirms a genuine timeout always carries status null, so this was never the seam misbehaving. Raising the bound would only lengthen the odds, which is the same defect with better luck. The test now drives gitOrThrow against a stubbed runGit that returns a synthetic TIMED_OUT result, so it asserts exactly what it always meant to -- that a timeout propagates as a throw -- with no timing dependence. Five consecutive runs are identical where the old one varied. I wrote this test in Wave 0; it is a real-race test by construction and CLAUDE.md says to replace those rather than re-run them. * chore(#3148): backfill changeset PR number 3192 --------- Co-authored-by: sim <sim@local>	2026-08-07 21:03:50 -04:00
Tom Boucher	cbd180c5cd	test(#3147): bound the lint/changeset/docs cluster onto the process seam (#3181) ... * test(#3147): bound the lint/changeset/docs cluster onto the process seam Migrates 69 unbounded sync spawn sites across 24 files. Allowlist 73 to 49. Two shared helpers move: tests/helpers/graphify.cjs (6 importing suites) and tests/fixtures/index.cjs, whose three quoted-argument shell strings became single argv elements rather than whitespace splits. changeset-lint's throw-native git() helper routes to gitOrThrow; migrating it to bare runGit would have silently swallowed a failure that is loud today. ingest-docs goes the other way -- its catch never rethrew, it degraded failure into data every call site asserts on, so throwIfFailed would have thrown where the original returned. The design doc said otherwise and was corrected. tsconfig-noemit runs a real tsc --noEmit and takes a bespoke 180000ms per the ensure-runtime-build precedent, not the 30000ms build-hooks norm -- that norm is for a file copy, and sizing against a label rather than the work is the same error in the opposite direction. * test(#3147): add toLegacyResult and settle review findings The seam exposed a throwing adapter (throwIfFailed) but no non-throwing one, so eight files independently re-derived the same unwrap back to the legacy {status, stdout, stderr} shape. That is the third time this epic produced N copies of one mechanism -- seven throw wrappers in Wave 1, fifty-two timeout constants in Wave 2, eight result adapters here. The pattern is that whenever the seam does not expose a mechanism, every suite re-derives it. toLegacyResult now sits beside throwIfFailed, with its own tests. Two sites are deliberately NOT converted: changeset-cli's runRender and runRenderIn return {status, report, stderr} from parsed JSON and never a raw stdout, so they are a different shape family. lint-legacy-dir-name keeps its local GUARD_TIMEOUT_MS: 30000 matches the build norm numerically but bounds a lint probe, not hooks bundling, and importing it would encode a coincidence as a relationship. --------- Co-authored-by: sim <sim@local>	2026-08-07 15:45:51 -04:00
Tom Boucher	3fac6e629f	test(#3145): bound the installer/runtime cluster onto the process seam (#3176) ... * test(#3145): bound the installer/runtime cluster onto the process seam Migrates 156 unbounded sync spawn sites across 47 files. Allowlist 120 to 73. Timeouts are sized from evidence already in the tree rather than a house default, because this wave spawns installers rather than git plumbing and an undersized bound does not catch a hang -- it manufactures CI flake, which is worse, since a flake gets re-run instead of investigated. install.test.cjs records a real spawnSync ETIMEDOUT at a 60000ms cap on a loaded bench while another lane passed the same commit in 12.7s, so full installs are bound at 120000ms against that recorded incident. Also adds an auditable escape to the guard's timeout ceiling. The 600000ms cap was set in #3143 from partial evidence, but fragment-single-edit- propagation carries a documented, load-tested 900000ms bound on a run that chains a full build plus eight generators -- the guard would have rejected a correct timeout the moment that file left the allowlist. A value above the ceiling is now permitted only with an inline allow-spawn-timeout-ceiling marker carrying a non-empty reason. It raises the ceiling; it never waives the requirement for a bound, which is asserted directly. install-shared.cjs keeps its hand-rolled assert rather than routing through throwIfFailed: its message embeds both streams, and throwIfFailed carries only a trimmed stderr. The message now also names the outcome, so a bounded timeout reads as such across its 38 importers instead of as expected null to equal 0. * test(#3145): extract class-norm timeouts and correct the build-hooks sizing A pre-PR review found 52 copies of four class-norm timeout constants across this wave. These are not per-suite fixture bindings -- they are shared facts about how long a class of subprocess takes, derived from a recorded bench incident. That norm already moved once (60000 to 120000 after a real ETIMEDOUT), and 52 copies would have drifted the next time it moved. Extracts tests/helpers/timeouts.cjs, where each norm is justified once, and converts the copies. A site that genuinely differs -- a real tsc compile, or regen:derived -- keeps its own local constant with its own justification. Also corrects a misclassification: scripts/build-hooks.js was sized as a build at 120000 in twelve places and 60000 in another, but it compiles and bundles nothing. Its own header says no bundling needed; it copies pre-built files and syntax-checks them with vm. Three different values bounded one script; now there is one. * test(#3145): fix red CI — lint self-match and a Windows chunk overrun Two failures on PR 3176. lint-allow-test-rule-refs read a RuleTester fixture as a real exemption. The fixture exists to prove an unrelated marker does NOT suppress the rule, so it carries that marker's literal text as test data. Split via concatenation, the same idiom no-unbounded-spawn-allowlist.test.cjs already uses for its own self-match problem. The explanatory comment needed the same treatment. The Windows shard 3/3 chunk was killed at its 600000ms budget. Output stopped seven minutes before the kill, so this was an overrun rather than a slow chunk: regenDerivedPropagatesSingleFragmentEditWithNoSecondSourceSurface runs regen:derived bounded at 900000ms, which is larger than the whole chunk budget, so the chunk killer always fires first and it can never complete there. Both the test and that bound predate this change; modifying the file pulled it into the Windows targeted set and exposed it. Skipped on Windows with the reason recorded; the Linux lanes cover it. The 900000 bound and its ceiling marker are unchanged -- they are correct. * test(#3145): refresh the stale test-timings cost table The Windows shard was killed at its 600000ms per-chunk budget. run-tests.cjs packs chunks by measured duration from tests/test-timings.json, and an unknown file falls back to the table's median weight -- advisory by design, but it silently underweights exactly the files that matter. Four of the failing chunk's 22 files were absent from the table, including the two heaviest: fragment-single-edit-propagation.install.test.cjs at 230s (it runs regen:derived) and agent-fragments-emission.install.test.cjs at 79s. Both were weighted as average, so the chunk's total weight read 53.68 against a budget of 60 and the packer produced a single chunk. Regenerated from a passing full-suite run, per the remedy the script itself documents. 700 to 770 entries, 70 added, 0 dropped -- verified, since gen-test-timings.cjs replaces the table wholesale rather than merging. Proven against the real packer: the same 22 files now weigh 103.91 and split into two chunks. No logic, budget, or timeout was changed; raising a budget to make a red gate pass is not a fix. --------- Co-authored-by: sim <sim@local>	2026-08-07 15:18:18 -04:00
Tom Boucher	1d208e5af6	test(#3144): bound the git/worktree cluster onto the process seam (#3152) ... * test(#3144): bound the git/worktree cluster onto the process seam Migrates 180 unbounded sync spawn sites across 19 files. Every previously unbounded call now carries an explicit timeout with a comment giving the number and why. The migration is not a callee swap. execSync and execFileSync throw on a non-zero exit and the seam never does, so each site was classified first: sites that rely on the throw route to gitOrThrow, and sites that already read .status to detect an EXPECTED non-zero -- an intended cherry-pick conflict, a rev-parse outside a repo driving a skip -- route to the never-throwing runGit instead, which would otherwise throw on exactly the exit being probed for. Two same-named git() helpers in worktree-cleanup.test.cjs have different return contracts, one trimmed and one raw; both are preserved rather than unified. Collapses five hand-rolled throw wrappers onto one throwIfFailed in git-fixture.cjs, which gitOrThrow now also uses so the shape cannot drift. Allowlist drops 139 to 120; BASELINE lowered to match. * test(#3144): fix pre-PR review findings Documents throwIfFailed in the CONTEXT.md glossary and CONTRIBUTING.md -- it became the shared throw mechanism without either doc naming it. Routes the sixth and seventh hand-rolled copies of the throw shape through throwIfFailed (worktree-baseref-install, worktree-safety-reap); the first consolidation missed both. Converts ci-rebase-check's 8 fixture-setup calls from unchecked runGit to gitOrThrow so a failed setup step aborts where it fails rather than surfacing later as a confusing failure against the wrong subject. Adds 12 direct unit tests for throwIfFailed, which until now was only exercised transitively.

Tom Boucher	2afe17bbdb	test(#3143): add the no-unbounded-spawn guard and throw-preserving git fixture (#3150) ... * test(#3143): add no-unbounded-spawn guard and throw-preserving git fixture Adds the ESLint rule local/no-unbounded-spawn, wired into the tests/**/*.cjs block, plus an allowlist that only ratchets down: a listed file with zero violations reports its own entry as stale. The rule resolves renamed destructures and chained requires rather than matching literal callee names -- both forms exist in the suite today and a name-only matcher leaves them permanently invisible. It resolves an options object held in a single-write const, which is what keeps process-seam.cjs, the bounded reference implementation, from flagging itself. timeout: 0 and anything above the 600000ms ceiling are rejected as only nominally bounded. Adds tests/helpers/git-fixture.cjs so a migrated execSync call site keeps its throw-on-non-zero contract; process-seam.cjs is unchanged. * test(#3143): prove the allowlist guards can actually fail Extracts the D4/D6/D7/D8 checks into pure helpers and drives each against a synthetic fixture carrying an injected violation. Without this the suite only proved that today's clean data passes, which a deleted check would also satisfy. * fix(#3143): close two ceiling and alias escapes found in review Nested arithmetic bypassed the ceiling entirely: the numeric evaluator only resolved a flat literal, so `timeout: 60 * 60 * 1000` (3600000ms, six times the ceiling) fell through to trusted and reported nothing. The evaluator now recurses through arithmetic and unary signs with a depth cap. Alias resolution was traversal-order dependent, not scope dependent: a call textually above its own require destructure saw an empty alias map and reported clean. The map is now built in a Program pre-pass. Also: an explicit timeoutMs:undefined no longer overwrites the git fixture default via spread, adds the missing seam-routed rule test, and de-duplicates the repeated try/catch in the fixture tests. --------- Co-authored-by: sim <sim@local>	2026-08-07 09:43:36 -04:00
