Tom Boucher	69e7afd0c7	chore(#3212): bounded quantifiers over document content — prohibition with teeth — Phase 4 (#3441) ... * feat(#3415): ship local/no-unbounded-quantifier, burn down ReDoS class Phase 4 of epic #3212 (ADR-3212 §5/§7, the final phase). New rule flags an unbounded */+/{n,} quantifier over a broad character class ([\s\S], dotAll ., or a 1-2-unit negated class like [^\n]/[^)\n] — the exact #2128-fixed shape) applied to a regex whose match target is data-flow-traced to readFileSync content. eslint-rules/lib/readfilesync-trace.cjs extracts the data-flow tracer shared with no-crlf-fragile-split (Phase 2) rather than a second copy — no-crlf-fragile-split refactored onto it with zero behavior change, parity-tested. Real triage, not 798 mechanical edits: the ADR's census (2026-08-08) screened every unbounded quantifier in the tree unscoped. Correctly scoped to readFileSync-derived content (matching Phase 2's own G2/G3 scoping), the rule found 162 real hits across two detection waves — the second wave (93) surfaced only after a genuine off-by-one bug in this rule's own first draft was caught while writing its RuleTester tests and fixed (the bug silently missed every directly-quantified [\s\S]* with no gap before the quantifier — exactly the class this rule exists to catch). 3 hits landed in production src/ (commands.cts, milestone.cts, roadmap.cts) and were each empirically timed against adversarial input (matching #2128's own measured-not-assumed precedent) — all confirmed linear-time/benign, left unbounded with a measured-evidence comment rather than mechanically bounded. The remaining 159 are test-file fixture parsing (test-author-controlled, fixed-size content, not adversarial input) — each suppressed with a specific, non-generic reason. Zero functional behavior changed anywhere in this diff. tests/no-pending-3212-markers.test.cjs locks the epic's own closing invariant (ADR §7: "assert zero pending #3212 markers remain") — ground truth confirmed trivially true today (no phase left any such marker behind), now regression-locked going forward. Design: .gsd/phase/chore-3415-prohibition-with-teeth/40-design.md Test matrix: .gsd/phase/chore-3415-prohibition-with-teeth/50-test-matrix.md Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com> * fix(#3415): correct rule category mislabel, add CI test-scope entry An orthogonal Standards-axis review found eslint-rules/no-unbounded-quantifier.cjs mistakenly carried meta.docs.category: 'Portability', copied from a sibling rule without realizing what that implied: docs/contributing/cross-platform- portability-rules.md governs an ADR-1703 rule family under a hard "zero escape hatches" contract (tests/portability-rule-disable-ban.test.cjs's PROTECTED_RULES bans eslint-disable for those rules entirely). This rule is not part of that family — it's ADR-3212 (ReDoS/CWE-1333), a different epic — and its eslint-disable-next-line suppressions (159 of them, added earlier this same phase after empirical benign-verification) are an intentional, correct design, not a bypass. Corrected to category: 'Best Practices', matching the actual precedent (no-adhoc-regex-escape.cjs, Phase 1 of the same epic, which is also correctly outside PROTECTED_RULES), and the rule's own docstring now states this explicitly so a future reader doesn't have to re-derive it. Also registers a new scripts/ci-test-scope.cjs bucket so editing this rule or the shared eslint-rules/lib/readfilesync-trace.cjs helper re-runs their own test suites under targeted CI selection — was previously unregistered and invisible to that fast-path (this PR's own gsd-test checkpoint runs the full suite regardless, so this only affects future narrowly-scoped PRs). Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com> * fix(#3415): bound no-unbounded-quantifier's own scanner (CWE-1333, ironic) Security review found the rule meant to catch algorithmic-complexity bugs had one of its own: hasUnboundedBroadQuantifier's negated-class inner scan walked from each `[^` occurrence to the next `]` (or EOF) with no bound, while the outer loop only ever advanced by one character — O(n²) total work on a pattern with many unclosed `[^` runs. Runs unconditionally inside checkPattern on any `new RegExp('literal string')` argument in any linted file, before the (cheap) readFileSync data-flow gate — so a single crafted string literal, no valid regex syntax required, could make `npm run lint` / CI hang. Empirically confirmed both the bug and the fix: pre-fix, n=4000/8000/ 16000/32000 chars took 30.8/115.6/463.8/1874.3ms (~4x work per 2x n, quadratic); extrapolated, the 300000-char repro from the finding would run ~165s. Post-fix (bail the inner scan once units exceeds the rule's own 1-2-unit scope, rather than continuing to hunt for a closing `]`), the same 300000-char input runs in 8.7ms via the real rule module, independently reconfirmed at 18ms via a fresh Linter.verify() call. New regression row in tests/no-unbounded-quantifier.rule.test.cjs asserts the RuleTester run on a 50000-char adversarial pattern completes and returns a defined result — no wall-clock assertion (CLAUDE.md Clock Seams / local/no-elapsed-assertion). Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com> * fix(#3415): triage 3 new sites, re-raise ceiling after upstream batch next merged 12 more PRs during this PR's review. Two consequences: - tests/edit-phase.test.cjs (fix #3262, unrelated) added 3 new content.match(/<tag>([\s\S]*?)<\/tag>/) reads of this repo's own workflow .md content — the same Class A pattern as the ~159 sites already triaged elsewhere in this PR. Suppressed with the same established reason. - lint-allow-test-rule-refs' ratchet ceiling needed re-raising again (301 -> 303) for the same reason as the two prior bumps: organic growth from unrelated, already-reviewed PRs landing concurrently, not a defect in this branch's own diff.

Tom Boucher	0624c5da6f	chore(#3212): src/text-lines.cts is the sole owner of line-terminator handling — Phase 2 (#3420) ... * test(#3413): failing-first suite for the line-terminator seam Phase 2 of epic #3212 (ADR-3212 §3/§6/§7). Tests only — src/text-lines.cts does not exist yet, so tests/text-lines.test.cjs fails with MODULE_NOT_FOUND at its require line, which is the intended RED. The frontmatter.test.cjs additions drive #3360 (confirmed-bug) fail-first: parseMustHavesBlock currently returns [] for every must_haves block on a CRLF-authored plan file, because \r is its own LineTerminator in ECMAScript and two /m-anchored \s* patterns can absorb it, inflating a captured indent by one character and tripping the "not nested under must_haves" guard. Verified locally against the current (unfixed) compiled module: both the direct repro and the silent-exit "blank line before must_haves:" variant return [] today. A parity property test (crlf vs lf must deep-equal for every block name) matches a pattern this maintainer has required repeatedly for prior CRLF fixes in this codebase (Cortex-recorded, verify_intent=held). The no-crlf-fragile-split.rule.test.cjs additions lock the eslint rule's future fix-hint text (pointing at splitLines()) and its self-reference non-violation (the seam's own correct \r?\n split must never flag itself). Design: .gsd/phase/chore-3413-text-lines-seam/40-design.md Test matrix: .gsd/phase/chore-3413-text-lines-seam/50-test-matrix.md * chore(#3413): src/text-lines.cts owns line-terminator handling Phase 2 of epic #3212 (ADR-3212 §3/§6/§7). Adds splitLines/normalizeEol/ detectEol/joinLines and migrates frontmatter.cts onto it. parseMustHavesBlock (#3360, confirmed-bug) returned [] for every must_haves block on a CRLF plan file. Root cause: \r is its own LineTerminator in ECMAScript, so under /m two \s*-anchored indentation lookups could match at the position INSIDE a \r\n pair and absorb the terminator, inflating the captured indent by one character and tripping the "not nested under must_haves" guard. Two silent exits, one with a diagnostic and one without (a blank line before must_haves: hits the silent path). Fixed by converting both lookups from a whole-string /m match to split-then-scan — splitLines first, then a per-line, non-/m match — the same structural pattern parseYamlRegion (30 lines away in the same file) already used safely. Nothing downstream of the two lookups changed; blockLines is now sliced from the already-split array instead of re-splitting a substring, but its contents are unchanged for LF input, and the per-line dash/kv parsing loop is untouched. A parity property test (CRLF and LF plans parse to identical must_haves for every block name) matches a pattern this maintainer has required repeatedly for prior CRLF fixes in this file's neighborhood (Cortex: 7 recorded decisions, verify_intent -> held). frontmatter.cts's other .split(/\r?\n/) call sites (parseYamlRegion, isFrontmatterShaped, sliceTopLevelFrontmatterSegments, spliceFrontmatter) are rerouted onto splitLines — a literal 1:1 substitution, zero behavior change, since splitLines IS that same regex plus a type guard. The 4 scripts/normalizeLineEndings copies (gen-registry, gen-loop-host- contract, gen-capability-registry, gen-context-index) are deleted and rerouted onto normalizeEol, which strips a bare unpaired \r exactly like the deleted copies did (not just \r\n pairs) -- verified against each script's own --check mode against its real generated output. local/no-crlf-fragile-split widens from tests/ to src/**/*.cts, with its fix-hint message now naming splitLines() instead of the raw regex -- the prohibition finally has a primitive to point at. Detection logic unchanged in this phase (deliberate scope limit, see design doc Known limits: the rule doesn't yet recognize safeReadFile/platformReadSync as a content source, and has no detector for the \s-adjacent-to-anchor shape that is #3360's actual mechanism -- the CLASS is converged by the direct fix + regression test regardless). joinLines/detectEol are NOT wired into frontmatter.cts's own write path (cmdFrontmatterSet/Merge -> platformWriteSync) -- verified that platformWriteSync already, unconditionally converts CRLF->LF on every .md write today as a pre-existing policy owned by a different module, and ADR-3212's backward-compatibility clause rules out a file-format change in any phase. Stated explicitly in Known limits rather than left for a reader to discover. Six-gate ripple: .gitignore, eslint.config.mjs (src/**/*.cts block), docs/INVENTORY.md + INVENTORY-MANIFEST.json (regenerated), CONTEXT.md glossary (Text Lines Module, mirroring Phase 1's Pattern Module entry). Design: .gsd/phase/chore-3413-text-lines-seam/40-design.md Test matrix: .gsd/phase/chore-3413-text-lines-seam/50-test-matrix.md * fix(#3413): fix 13 pre-existing CRLF-fragile splits the widened rule found Widening local/no-crlf-fragile-split from tests/ to src/**/*.cts (the previous commit) immediately surfaced 13 real, pre-existing violations across 10 files -- undetected until now because the rule never scanned src/. This is the exact defect class ADR-3212 exists to close, playing out again one phase after Phase 1 hit the same shape ("the new lint rule -- once live -- found 27 more"). Per CLAUDE.md's no-defer rule, fixed inline rather than deferred or suppressed; there is no established suppression convention for this rule in src/ and inventing one now would undermine the point of widening it. audit.cts, broken-windows.cts, core-utils.cts, init.cts, milestone.cts, phase.cts (x3), profile-output.cts, roadmap.cts (x2): bare-\n splits or regex character classes widened to \r?\n / [^\r\n], each following the same pattern already established migrating frontmatter.cts. phase-estimation.cts: `\r?(?:\n|$)` restructured to `(?:\r?\n|\r?$)` -- already semantically CRLF-safe, but the rule's lexical scanner doesn't recognize \r? guarding a group (only \r? immediately before a literal \n). Verified the two forms are equivalent across all four EOL/EOF cases before restructuring, not assumed. roadmap-upgrade.cts needed two coupled sites, not the one flagged line: computeMigrationPlan and applyMigration must agree on line representation for the lines[edit.lineIndex] === edit.from equality check to hold, and the write-back needed joinLines + detectEol -- a plain lines.join('\n') was silently flattening a CRLF ROADMAP.md to LF wholesale on every migration. This is the first real production consumer of joinLines/detectEol in this epic (frontmatter.cts's own write path doesn't use them -- see the previous commit's Known limits). Fixing the 13 flagged sites surfaced 4 more adjacent same-shape sites the rule doesn't track (.search() and new RegExp(dynamicString) aren't in its tracked call/construction set). Investigated each empirically -- hand-tracing this exact bug class already produced one wrong conclusion earlier in this phase (a detectEol design-doc arithmetic error), so these were verified with real CRLF fixtures rather than reasoned about on paper: - audit.cts (scanTodos): REAL bug, fixed. `bodyMatch.trim().split ('\n')[0]` leaked a trailing \r into a user-visible todo summary on CRLF input -- .trim() only strips the string's outer edges, not a \r sitting mid-string before the first bare \n. Now splitLines(...) [0]. - phase.cts (cmdPhaseInsert, bullet-style branch): REAL bug, fixed. [^\n]* in targetBulletPattern swallowed a line's trailing \r on CRLF input, shifting the computed insert position to land INSIDE the \r\n pair; combined with a hardcoded '\n' bullet separator, a CRLF ROADMAP.md ended up with a mixed CRLF/LF result after an insert. Fixed with two coupled changes (either alone still corrupts, verified both ways): [^\r\n]* in the pattern, and the new bullet's leading terminator now comes from detectEol(rawContent). - roadmap.cts (cmdRoadmapAnnotateDependencies phase-boundary scan): investigated, genuinely safe, left untouched. The .search(/\n#{2,4} .../) boundary-finder and the [^\n]*-based heading match were empirically verified on a 3-phase CRLF fixture -- the only stray \r ends up at the tail of an intermediate phaseSection string that is only ever used for .test()-based idempotency checks, never for an exact-match comparison or written back to disk. No corruption on round-trip. Every fix re-verified: npm run build:lib clean, npx eslint 'src/**/*.cts' --no-cache reports 0 problems (was 13), and each fixed function's existing LF-input tests were spot-checked unchanged. * fix(#3413): apply orthogonal review findings Two isolated review engines (correctness + security) ran against the full diff and found three majors, one real security issue, and several disclosure-worthy minors. All fixed or explicitly disclosed with evidence; nothing deferred. MAJOR — detectEol's tie-break contradicted its own documented contract. Code returned '\n' on a 1:1 crlf/bare-LF tie; every doc (design doc, CONTEXT.md, the function's own comment) says ties resolve to '\r\n'. The existing test masked this by reusing the same tie fixture the buggy code happened to satisfy, rather than a genuine LF-majority case. Root cause: an Edit attempted earlier in this phase to fix this exact arithmetic error was blocked by the tier guard, and a later dispatch was incorrectly told it had already landed. Fixed: condition is now crlfCount >= bareLfCount; the test fixture corrected to a genuine 2:1 majority, with a new explicit tie-case test. MAJOR — phase.cts's cmdPhaseInsert built an EOL-aware bulletEntry via detectEol(rawContent), justified by a comment claiming a hardcoded '\n' corrupts a CRLF ROADMAP.md. False: this write goes through platformWriteSync, whose normalizeContent/_normalizeMd unconditionally converts CRLF->LF for any .md target — the templating was inert dead code, erased before the file is ever written. Reverted to hardcoded '\n', comment corrected to state the true reasoning. The separate [^\n]* -> [^\r\n]* widening one function up (a real splice-position fix, independent of final EOL) was kept. MAJOR — roadmap-upgrade.cts's stated rationale for switching onto splitLines/joinLines was wrong (both functions always agreed on line representation, before and after — the claimed equality-check risk never existed), and the change it justified introduced a real regression: forcing every line onto one dominant terminator silently rewrites untouched lines' EOL on a mixed-CRLF/LF ROADMAP.md. This write path uses raw fs.writeFileSync, not platformWriteSync, so unlike the phase.cts case above the regression is genuinely live. Fixing this took two attempts. The first attempt (revert to split('\n')/join('\n') plus a suppression comment) was correctly blocked by an agent that discovered local/no-crlf-fragile-split is a PROTECTED_RULES entry in tests/portability-rule-disable-ban.test.cjs — a hard, out-of-band, ADR-1703-governed guardrail banning any eslint-disable of this rule anywhere in src/**/*.cts. That agent also detected and correctly disregarded an injected instruction that appeared in tool output during a git operation, per this session's untrusted-content policy. The actual fix: computeMigrationPlan reverted to roadmapContent.split('\n') (confirmed lint-clean — the rule's data-flow tracking only follows a variable's initializer, and this one is declared empty then reassigned in a try block). applyMigration's write-back now splices edits against the ORIGINAL content string via indexOf('\n', pos) boundary-walking instead of a full split/rejoin, so every untouched character — including every line's own terminator — is copied byte-for-byte. A capture-group split (/(\r\n|\n)/, preserving terminators inline) was tried first and empirically confirmed to still trip the rule before this approach was chosen instead. MINOR (security) — roadmap.cts's cmdRoadmapAnnotateDependencies used the STRING form of String#replace, so $&, $`, $', $1-$9 inside must_haves.truths content (author-controlled) were interpreted as replacement directives, splicing unrelated ROADMAP.md text into the result. Fixed with the function-replacement form, which is never pattern-interpreted. Verified before/after with the reviewer's exact repro. Also disclosed rather than silently left: test matrix row 31 (four planned CRLF-materialized regression tests) was never implemented as separate files — corrected to record the actual verification (a manual --check run plus incidental existing coverage via each script's normalizeLineEndings: normalizeEol alias). parseMustHavesBlock's LF behavior was claimed byte-for-byte unchanged but the old yaml.indexOf(blockMatch[0]) substring search could match an unrelated earlier occurrence of the header text (e.g. inside a quoted value) — the split-then-scan fix incidentally also closes this, a strict improvement now recorded in the design doc rather than left implicit. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * fix(#3413): checkpoint 2 red — missing eslint ignore entry, RuleTester config error Checkpoint 2 came back red with 5 failures on the reviewed sha, both gaps genuinely undetectable by any local gate. eslint.config.mjs was missing the 'gsd-core/bin/lib/text-lines.cjs' ignores-list entry (ADR-457: generated .cjs artifacts are excluded from direct type-aware linting). Phase 1's sibling entry (pattern.cjs) sits two lines above it and was the exact precedent read while researching the six-gate ripple for this module -- missed anyway. Caught by tests/repo-invariants.test.cjs's bin/lib coverage-tracking test, which only runs on the remote suite. tests/no-crlf-fragile-split.rule.test.cjs's row-32 case specified both `messageId` and `message` on the same RuleTester error assertion -- ESLint's RuleTester rejects that combination outright. This existed since the test was first authored and was never caught locally: `npx eslint` only lints the file's syntax, it does not execute RuleTester, and local `node --test` is hard-blocked in this repo -- the assertion had never actually RUN before this checkpoint. It was even present in checkpoint 1's failure list, listed there as one of the "expected RED" tests; I matched it against my expected-failures list by test NAME only and never inspected the actual failure detail closely enough to notice it was failing for the wrong reason (a RuleTester config error, not the intended message-text mismatch). Fixed by keeping `message` (the exact-text assertion the test exists to make) and dropping `messageId`. Verified the crlfFragileSplit message string in eslint-rules/no-crlf-fragile-split.cjs matches this assertion character-for-character, and swept every other invalid case in the file for the same double-specification bug (none found -- all pre-existing cases use messageId alone).

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
