* test(#1951): add failing-first tests for reversibility tagging Red phase for issue #1951 (reversibility tagging: classify decisions by undo cost, gate one-way doors behind a checkpoint:decision). Tests assert, per the issue's acceptance criteria: - discuss-phase CONTEXT.md template records a **Reversibility:** field with a rationale on captured decisions, and states it is optional - gsd-planner @-references planner-reversibility.md and stays under the 49152-char agent cap (LARGE_CAP, tests/agent-size-budget.test.cjs) - a one-way rating inserts a checkpoint:decision before the dependent task; reversible inserts none; costly is flagged but never blocks - the taxonomy defaults to reversible when unsure (checkpoint-fatigue guard) and inserting a checkpoint implies autonomous: false - docs/reference/plan-md.md documents <reversibility> as optional with all three ratings - --no-reversibility-gates parses to REVERSIBILITY_GATES=false, is injected into the planner prompt, and is advertised in the command argument-hint and help full mode (argument-hint parity) - the override suppresses the gate but still persists the rating - cmdVerifyPlanStructure accepts every rating and the absent case (additive-validator guarantee, behavioral via runGsdTools) - parity: thinking-models-planning.md #4 adopts the canonical three-level taxonomy and the binary REVERSIBLE/IRREVERSIBLE vocabulary is gone - no content loss from the planner extraction made to fit under the cap Prose-contract assertions are Red until the implementation lands. The behavioral validator assertions pass immediately — regression guards proving the validator already accepts unknown optional tags. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> * feat(#1951): reversibility tagging — gate one-way-door decisions Classify planning decisions by what undoing them would cost, and give a one-way door a human beat before the agent walks through it (issue #1951, The Pragmatic Programmer Topic 15 'Reversibility'; Bezos's one-way/two-way door framing). Acceptance criteria met: - discuss-phase records an optional reversibility rating with a rationale on <decisions> entries in the phase CONTEXT.md template. Unrated decisions are treated as reversible, so existing phases are unaffected. - a one-way rating makes gsd-planner insert a checkpoint:decision before the task that implements the decision, reusing the existing checkpoint mechanism -- no new checkpoint machinery. - reversible ratings trigger no checkpoint; costly ratings are flagged in the plan but never block. - the rating persists on the task as the optional <reversibility rating=> element. cmdVerifyPlanStructure accepts every rating and the absent case; the structural validator does not reject unknown optional tags. - --no-reversibility-gates (REVERSIBILITY_GATES=false) suppresses checkpoint insertion for intentionally-unattended runs while still recording ratings -- the override changes what stops the run, not what the plan remembers. Single taxonomy, not two: references/thinking-models-planning.md #4 already shipped a binary REVERSIBLE/IRREVERSIBLE classification and is loaded by both gsd-planner and gsd-plan-checker. It is rewritten onto the canonical three-level vocabulary and now points at planner-reversibility.md as the taxonomy owner, with a parity test that fails if the surfaces diverge (DEFECT.GENERATIVE-FIX-DIVERGENCE). agents/gsd-planner.md sat 47 chars under the 49152 LARGE_CAP, so the checkpoint DO/DON'T guidance was relocated verbatim into planner-antipatterns.md -- already @-referenced from the same section for the same topic, so the planner still loads it and nothing was dropped. A test guards the relocation against content loss. Files: gsd-core/references/planner-reversibility.md (NEW, canonical taxonomy + emission rules + anti-patterns), gsd-planner.md, plan-phase workflow/command/help (flag wiring + parity), plan-md.md schema, discuss-phase context template, CONTEXT.md glossary, INVENTORY + manifest, size baselines, install goldens, plugin skills regen, changeset. Closes #1951 Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> * fix(#1951): address orthogonal review findings Two isolated reviewers (correctness + security), neither of which authored the change. Every finding fixed: Security — the rationale is untrusted input (ADR-1577). It originates in conversation and flows CONTEXT.md -> planner -> PLAN.md -> executor, each hop an LLM reading the previous hop's output, with no validation on the path. planner-reversibility.md and the discuss-phase template now state it is data and never instructions, and name the </reversibility> early-termination hazard explicitly -- a rationale that closes its own element injects sibling structure the executor reads as real tasks. Four tests guard it. Correctness 1 — nothing machine-enforced the feature's own promise: a task rated one-way with no preceding checkpoint:decision validated as fully clean, so a planner error silently reopened the gap this feature exists to close. cmdVerifyPlanStructure now warns on an ungated one-way rating. A warning, not an error: <reversibility> stays additive and the plan stays valid. Four tests cover ungated (warns), gated (silent), still-valid, and reversible/costly never flagged. Correctness 2 — pass-always test. The --no-reversibility-gates parse test substring-matched the whole workflow file, and plan-phase.md prose mentions both tokens in one sentence, so it passed with the bash conditional deleted: it was testing the documentation, not the parser. Now scoped to the fenced bash blocks and matched as one physical line, with a negative control confirming prose alone cannot satisfy it. Correctness 3 — costly had no itemized emission rule, only one-way did, so two agents could diverge on whether to tag costly at all. Correctness 4 — template convention break: the example ratings were bare while every sibling field uses [...] to signal substitution, inviting an LLM to copy one-way/costly forward as boilerplate. Now bracketed. Correctness 5 — latent false-green: .includes('reversible') also matches inside irreversible/irreversibility, which appear in anti-pattern prose, so a surface that dropped the real taxonomy entry would still pass. Now word-boundary matched. ADR-857 phase-6 ceiling — the first gsd-test run caught plan-phase.md 1216 bytes over its frozen 94519 ceiling (it had 49 bytes of headroom on next). The ceiling may only rise for privileged host machinery, and reversibility gating is optional-feature logic, so the wiring was slimmed to its minimum and the explanatory prose moved to the reference files the planner already loads. plan-phase.md is now 94400 bytes -- 119 under the ceiling and 70 bytes SMALLER than on next, so the host loop shrank while gaining the feature, which is what phase 6 ratchets toward. The tracer contract (tests/tracer-bullet.test.cjs) is unchanged. Lint — fixed an unnecessary non-null assertion in verify.cts and a CRLF-fragile bare \n regex in the new test (DEFECT.WINDOWS-CRLF-TEST- PORTABILITY, the #1658/#1668/#2206/#2449/#2450 class). Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> * test(#1951): checkpoint fixture must carry the common task elements The gated-one-way fixture built a checkpoint:decision task from the abbreviated skeleton in gsd-planner.md, which shows only the checkpoint-specific elements (<decision>/<context>/<resume-signal>). cmdVerifyPlanStructure requires <name> and <action> on EVERY task regardless of type, so the fixture failed validation for reasons that had nothing to do with reversibility: errors: ["Task missing <name> element", "Task 'unnamed' missing <action>"] Caught by gsd-test on 14d14a39 (2 failures, both this fixture). The canonical shape is in tests/verify.test.cjs:266 — a checkpoint task carries <name>/<files>/<action>/<verify> like any other. Fixture corrected to match. Verified behaviorally against the real gsd-tools CLI across all four cases: gated one-way (valid, silent), ungated one-way (valid, warns), costly (valid, silent), absent (valid, silent). Not a product defect: the validator's every-task contract is intentional and pre-existing, and docs/reference/plan-md.md scopes its required-element list to type=auto/tracer only because those are the elements a planner must author, not because checkpoints are exempt from <name>. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> * chore(#1951): backfill changeset pr number to 2471 * fix(#1951): CodeQL incomplete-sanitization + prompt-injection scan collision Both CI failures were real defects in code this PR added, not false positives. CodeQL js/incomplete-sanitization (high), reversibility-tagging.test.cjs:46 — the namesRating helper built its regex with `rating.replace(/[-]/g, '\\-')`, which escapes the hyphen but not backslash, so the escape was incomplete. It was also unnecessary: `-` carries no special meaning outside a character class. Replaced with a complete metacharacter escape (backslash included). Word-boundary behavior verified unchanged across all three ratings — notably that "irreversible" prose still does not satisfy a "reversible" match, which is the false-green this helper exists to prevent. Prompt injection scan — the checkpoint fixture used the human-verification child element inside <verify>. That tag name is a fake-instruction-boundary pattern in scripts/prompt-injection-scan.sh, and the scan runs over changed files, so copying the shape from tests/verify.test.cjs (unflagged only because it is not in this diff) tripped the gate. Switched to the documented plain-prose <verify> form. The first attempt at that fix failed the same gate a second time: the comment explaining the collision quoted the offending tag literally. The comment now names it in prose instead — the scanner does not care whether a match is code or commentary, which is the whole point of the DEFECT.PROMPT-INJECTION-SCAN-COLLISION note in CLAUDE.md. Verified locally before push: scan reports 0 findings across 57 changed files, eslint clean, and both fixtures still validate as designed (gated one-way silent, ungated one-way warns, neither errors). Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> * test(#1951): record measured cost and halve gsd-tools spawns The Windows shard 1/3 job timeout was traced to the sharding layer, not to this PR's assertions — see #2472. Two contributing factors were this file's own, and are fixed here. 1. tests/test-timings.json had no entry for reversibility-tagging.test.cjs, so scripts/run-tests.cjs weighted it at the table's median fallback (~315ms) for LPT chunk packing. It actually measures 5595ms — an 18x under-weight. Recorded the measured value from the green gsd-test run (max across the node22/node24 lanes, per gen-test-timings.cjs's convention). Only this one entry: a full regen churns 634 entries of run-to-run drift, and the table is explicitly advisory and un-gated, so a 637-line diff does not belong in a feature PR. 2. Each verifyPlan() spawns gsd-tools, which dominates this file's cost. Spawns cut from 9 to 6 with no coverage lost: - the ungated-one-way warning and its stays-valid assertion now share one plan instead of building the same plan twice; - the reversible/costly never-flagged-as-ungated test was strictly subsumed by the additive suite, which already runs those two ratings ungated and asserts no /reversibilit/ warning at all — and the gate warning's text contains both "reversibility" and "one-way", so the broader assertion catches it. It only re-spawned gsd-tools twice to prove the same thing. Both are symptom fixes. The shard imbalance itself (19/11/10 minutes against a 20-minute cap, from a cost-blind round-robin partition that also reshuffles downstream files whenever one is inserted) is tracked in #2472. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> * test(#1951): checkpoint fixture adopts the #2444 type-branched contract Surfaced by rebasing onto next, which gained #2444 (branch plan-structure validation on task type=checkpoint:*) while this PR was in review. cmdVerifyPlanStructure no longer applies one required-element set to every task. A checkpoint:decision now requires <name> + <resume-signal> + <decision> + <options>, and is exempt from the <action>/<verify>/<done>/ <files> set that auto and tracer tasks carry. The gated-one-way fixture predated that split and failed on the new requirement: errors: ["Task 'Task 0: Confirm the on-disk format' missing <options>"] Fixture rewritten to mirror the checkpoint:decision contract exactly — real <options> with two <option> children — rather than padding it with fields checkpoints no longer need. That also drops the plain-prose <verify> the earlier revision carried purely to dodge the prompt-injection scan; a checkpoint task has no <verify> requirement at all, so the workaround is moot. Verified against the real gsd-tools CLI across all four cases: gated one-way (valid, silent), ungated one-way (valid, warns), costly (valid, silent), absent (valid, silent).
