* test(#2444): failing-first regression for checkpoint:* plan-structure validation Add acceptance-criteria tests covering the three canonical checkpoint task types (human-verify, decision, human-action) plus an unknown-subtype forward-compat case. Each canonical type must pass verify plan-structure when it carries its type-specific required fields (per gsd-core/references/checkpoints.md), and must be flagged when those fields are missing. Non-checkpoint tasks keep the existing <action>/<verify>/<done>/<files> requirements unchanged (AC3 regression guards). The existing 'errors when checkpoint task but autonomous is true' fixture is updated to use the canonical checkpoint:human-verify triple (<what-built>/<how-to-verify>/<resume-signal>) so it does not collide with the new per-type validator; the assertion (autonomous is not false) is unchanged. * fix(#2444): branch plan-structure validation on task type=checkpoint:* cmdVerifyPlanStructure unconditionally required <action>/<verify>/<done>/ <files> on every task, so every checkpoint:* task — which uses the checkpoint convention's type-specific fields instead — was reported as a structural error. Checkpoint-heavy phases produced walls of false findings. The fix introduces two pure helpers in verify.cts: - extractPlanTaskInfos(content): single ReDoS-safe pass over <task ...>...</task> blocks that captures BOTH the opening-tag attribute string (so the type= selector is not lost, as it is with extractTaggedBlocks) and the body, returning a typed PlanTaskInfo. - validatePlanTaskStructure(task): branches on the task's type. checkpoint:human-verify requires <what-built>/<how-to-verify>/ <resume-signal> (the canonical triple). checkpoint:decision requires <decision>/<options>/<resume-signal>. checkpoint:human-action requires <action>/<instructions>/ <verification>/<resume-signal>. Unknown checkpoint:* subtypes require only the universal <resume-signal> (forward-compat). All other types keep the historical <action>/<verify>/<done>/<files> requirements unchanged. Canonical reference: gsd-core/references/checkpoints.md. Per-type field sets validated against the documented templates in agents/gsd-planner.md and gsd-core/templates/phase-prompt.md. * fix(#2444): re-resolve body-parser to 2.3.0 in lockfile (GHSA-v422-hmwv-36x6) GHSA-v422-hmwv-36x6 (body-parser DoS via invalid limit value, low severity, published 2026-07-20T23:23:26Z) made tests/npm-integrity-gate.test.cjs (#3588: root workspace production tree has no advisories) fail any subsequent npm audit --omit=dev. The advisory affects body-parser >=2.0.0 <2.3.0 pulled transitively via @anthropic-ai/claude-agent-sdk -> @modelcontextprotocol/sdk -> express -> body-parser@2.2.2. express@5.2.1 already declares body-parser as ^2.2.1, so 2.3.0 is a valid re-resolution within express's own compatibility range — no override needed. Regenerated the lockfile via 'npm audit fix --omit=dev' which re-resolves transitive deps within their declared ranges; package.json is unchanged. Verified: npm audit --omit=dev reports 0/0/0/0/0 advisories; body-parser now reads as 2.3.0 in 'npm ls body-parser --omit=dev'. * test(#2444): close review gap-closure tests + harden type-attr charset Orthogonal review (code-review + security-review subagents) returned APPROVE on Standards and Spec. Per the playbook's zero-tolerance policy, address every Low finding: Spec gap-closures: - AC3 verbatim: add explicit <done> and <files> regression tests for non-checkpoint tasks (pre-existing tests only covered <action> and <verify>). - AC2: add checkpoint:decision missing <decision>, checkpoint:human-action missing <action>, checkpoint:human-action missing <verification> cases (the implementation enforces all of these; only one missing-field case per type was previously tested). - Remove the duplicate 'returns error for nonexistent file' test that leaked into the new describe block from the insertion edit. Security hardening (Low-sev, defense-in-depth): - Tighten the task type= attribute extractor in src/verify.cts from [^"'>\s]+ to [\w:-]+ so a hostile type= attribute cannot carry markup fragments (e.g. type=evil<fragment) into the verifier's typed JSON output. All legitimate type values (auto, tracer, manual, checkpoint:human-verify, checkpoint:decision, checkpoint:human-action, checkpoint:tdd-review) match the tighter charset. - Add adversarial regression test asserting type=evil<fragment surfaces as 'evil' (capture stops at '<'), with no markup chars (< > ( ) &) in the surfaced type field. * docs(changeset): add Fixed fragments for #2444 PR Two fragments: - sturdy-jays-tumble.md: the verify plan-structure checkpoint fix - witty-badgers-hum.md: the body-parser 2.3.0 re-resolution PR number backfilled to 0 placeholder per CLAUDE.md 'PR Number Handling'; will backfill to the real PR number immediately after gh pr create returns. * docs(changeset): backfill PR number to 2473 Per CLAUDE.md 'PR Number Handling': backfill the placeholder pr:0 with the real PR number returned by gh pr create.
