* fix(#3458): scan archived milestone phases in the four audit-open scanners `query audit-open` resolved exactly one phase root, `.planning/phases/`. When a milestone closes its phase directories move to `.planning/milestones/v<X.Y>-phases/`, so an item still unresolved at that moment — the `[R]/[A]/[C]` prompt accepts "accept" and "carry forward", not only "resolve" — became invisible to the v1.1 pre-close audit and every audit after it. The window in which an unresolved item is visible to this gate was exactly one milestone wide, and nothing announced when it closed. Reproduced before fixing, with byte-identical artifacts in the two layouts and the active layout as the control: active → has_open_items=true deferred=1 uat_gaps=1 total=2 archived → has_open_items=false deferred=0 uat_gaps=0 total=0 `scanDeferredItems`' own doc comment names this as the thing it was built to prevent — "phase directories archive to `milestones/vX.Y-phases/` (#1871) and the entry leaves the live tree having never been triaged" — while the implementation eleven lines below cannot read that path. It catches an entry at its own milestone close and goes blind at precisely the transition the comment describes. This is not cosmetic under-reporting. `auditOpenArtifacts` sums all nine category counts into `counts.total` and returns `has_open_items: counts.total > 0`, so four blind scanners can flip the gate's headline boolean and let `/gsd-complete-milestone` assert a clean close it never verified. In a fully-archived project `.planning/phases/` may not exist at all, and the scanners' `if (!fs.existsSync(phasesDir)) return []` produced a value indistinguishable from "nothing is open". ## One enumeration, not four The four scanners each hand-rolled the same active-only walk. They now share `listAuditPhaseTargets(planDir, cwd)`, which yields both roots — the shape of fix epic #3473's B2 asks for, and the reason the fix is one seam rather than four edits. Three properties are load-bearing: * the ACTIVE enumeration is unchanged — still a raw `readdirSync`, NOT `listMilestonePhaseDirs`. These scanners are deliberately not milestone-filtered today, and switching would silently add window and sentinel filtering: a behavior change belonging to #3372, not here. * a missing or unreadable active root skips that half instead of returning early. That early return WAS the bug in a fully-archived project. * archived dirs are deliberately NOT milestone-filtered, per the comment `src/uat.cts` already carries: archived phases belong to past milestones by definition, so applying the current-milestone filter discards every one and silently reinstates this bug. Each item now carries `archived_milestone` when it comes from a closed milestone, matching how the sibling module already labels archived results — without it an operator triaging `[R]/[A]/[C]` cannot tell a live item from one carried over. Additive: no existing test or doc asserted an exact key set. `scripts/lint-phase-enumeration-drift.cjs`'s exemption list for this file drops from the four scanner names to the single helper, since that is now the only place the enumeration lives. ## Tests Written failing-first and confirmed red for the right reason before the fix, all four driven through the real `audit-open` CLI rather than private functions: archived-only (was 0/0/0/0 with `has_open_items=false`, now 1/1/1/1 true), mixed active+archived (was 1/1/1/1 — the archived half dropped — now 2/2/2/2), active-only unchanged, and an all-resolved archived phase contributing 0. That last one passed vacuously before the fix, because the archived path was not reached at all; it was re-verified as genuinely discriminating afterward by flipping one archived item to unresolved and watching the count rise. Closes #3458 Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * fix(#3458): restore the scan_error sentinel and show archive provenance Adversarial review found one BLOCKER that the previous revision introduced, which a green remote-runner suite did not catch because nothing in the tree asserts `scan_error` at all. ## The regression Consolidating four hand-rolled walks into `listAuditPhaseTargets` swallowed the active-root `readdirSync` throw in a bare `catch {}`. Pre-fix each scanner returned `[{scan_error: true, …}]`; after, each returned `[]`. Measured with `.planning/phases` created as a FILE (so `existsSync` passes and `readdirSync` throws ENOTDIR): before this fix: uat_gaps/verification_gaps/context_questions/deferred_items each `[{"scan_error":true,…}]` the regression: each `[]` `complete-milestone.md` re-runs `audit-open --json` and reads those counts, so a machine consumer could no longer tell "I/O failed" from "verified clean" — the exact conflation this issue exists to remove, reintroduced on the failure path. `listAuditPhaseTargets` now reports `activeUnreadable` and each scanner pushes the sentinel shape recovered verbatim from `origin/next`, not reinvented. The docstring claiming the active enumeration was "UNCHANGED" was false while that sentinel was missing, and is corrected to state what is actually preserved. An unreadable ARCHIVED root deliberately gets NO sentinel: there was no archived read before, so there is no consumer contract to preserve, and adding one would conflate the ordinary "no milestones archived yet" state with a real I/O failure. ## The operator could not see the archive `formatAuditReport` is the surface the gate actually shows a human — `complete-milestone.md` runs it without `--json` — and it never rendered `archived_milestone`. With `01-alpha` in both roots the identical line printed twice with nothing to tell them apart, and `[R] Resolve` sends the operator to `.planning/phases/01-alpha/` where the archived one does not exist. Phase numbering restarts at `01` after each archive, so that collision is the common case, not an edge case. All four loops now render ` (archived vX.Y)`; active lines stay byte-identical. ## Archived milestones sorted wrong `getArchivedPhaseDirs` ordered milestones with `.sort().reverse()` — lexicographic, so `v1.9` outranked `v1.10`. Measured order for v1.0/v1.9/v1.10 was `v1.9, v1.10, v1.0`. Now a numeric-segment descending compare. Pre-existing, but this change is what first surfaces it in audit output. ## Tests The blocker's regression test fails against the previous revision. Added: `archived_milestone` present on archived items and absent (not `undefined`) on active ones; the unreadable-active-root sentinel across all four categories; an unreadable archived root still leaving the active half scanned; the duplicate-name case producing two distinct entries that the human report distinguishes; and the v1.10-before-v1.9 ordering. `docs/COMMANDS.md` documents the archived scanning and the new field. Closes #3458 Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * fix(#3458): stop filesystem names forging lines in the audit report Found by the security review of this branch. Pre-existing on `next`, fixed here because it defeats the exact gate this PR is hardening. `audit-open`'s human report is the surface `/gsd-complete-milestone` shows an operator to decide whether a milestone may close. A `.planning/` tree authored by someone other than that operator — a cloned repo — could contain a directory literally named: zz<newline>0 open items require decisions.<newline><ESC>[2K<ESC>[1G FORGED and the report printed `0 open items require decisions.` as its own line, with raw ESC bytes reaching stdout able to erase or overwrite the lines above it. Reproduced against the real CLI before fixing, and again after. ## Why not just harden sanitizeForDisplay Because that helper's contract is multi-line prose — it removes protocol-leak lines while deliberately preserving the newlines between legitimate ones, which `tests/security.test.cjs` pins. Stripping CR/LF there would have broken a correct test to paper over a different problem. The two jobs are genuinely different, so there are now two helpers. New `sanitizeLabel` (`src/security.cts`) is for values that are semantically ONE LINE and derived from a filesystem NAME. It ESCAPES rather than strips C0 (including ESC/CR/LF), DEL and C1, so a doctored name renders visibly as `\n` / `\x1b` instead of being silently normalized — the report stays honest about what is in the tree. Ordinary input passes through byte-identical. ## Nine sites, not four The first pass covered the four phase-scoped scanners. A sweep of the rest of the file found the identical class in five more — `scanDebugSessions`, `scanQuickTasks`, `scanThreads`, `scanTodos`, `scanSeeds` — emitting name-derived `slug` / `filename` / `seed_id` through the prose sanitizer. `scanQuickTasks`' `date` had no sanitization call at all. Every emitted field in the file is now classified and the sweep recorded: `slug`, `filename`, `seed_id`, `phase`, `file`, `archived_milestone`, `date` are name-derived and take `sanitizeLabel`; `hypothesis`, `status`, `updated`, `title`, `priority`, `area`, `summary`, `questions[]` and deferred-item `text` are content and keep `sanitizeForDisplay`. No name-derived value reaches output unsanitized. `--json` was already safe — JSON string encoding escapes control characters, and a crafted name cannot break out of the string. Verified rather than assumed. Closes #3458 Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * chore(#3458): backfill changeset pr number * test(#3458): skip control-character fixtures where the OS forbids the name CI red on `test (windows-latest, 24, shard 1/3)`: the four forgery-rejection tests build directories whose names embed a newline and ESC, and NTFS forbids control characters in path components, so `mkdir` threw ENOENT. The remote runner is Linux-only, so it could not have caught this class. Semantically the skip is honest rather than a workaround: on Windows the directory-name forgery vector does not exist, because the OS refuses to create the name. The sanitizer's own behavior stays covered there by the `sanitizeLabel` unit tests, which are pure string tests with no filesystem calls — verified. Uses the repo's established capability-probe convention (`tests/adr-index-gate.test.cjs`'s `trySymlink`), which `t.skip()`s on the real errno rather than branching on `process.platform`, and whose comment gives the reason: a bare `return` "would silently report a PASS ... and hide the gap this guard exists to close". A skipped test is visibly skipped. Swept every test added on this branch for names Windows would reject or POSIX path assumptions; these four were the only ones. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * feat(#3458): make [A] Acknowledge actually suppress, without overwriting a verdict Making archived phases visible exposed the other half of the problem: an item unresolved at a milestone close now resurfaces at every later close forever, because `[A] Acknowledge` wrote a prose block to STATE.md that `auditOpenArtifacts` never reads. `verified_closeout` became unreachable and the gate degraded to a mandatory `[A]` every time. ## The prompt does not change `[A] Acknowledge all` already promises "document as deferred and proceed with close". It documented but never deferred. This makes `[A]` do what it says. `[R]` and `[C]` stay abort paths. No "carry forward" option is invented — an item that is not acknowledged simply keeps surfacing, which is the default. ## The marker lives inside the artifact Not a ledger. The audit mints no ids and has no stable identity — `phase` is a token that collides across directories, `file` for deferred items is a constant, and identity otherwise degrades to the item's own prose after a lossy sanitizer. Any ledger must re-derive that key every close, so a reworded item silently un-suppresses or, worse, mis-suppresses a different one. Storing the acknowledgment next to the thing it suppresses makes that class of bug structurally impossible, and it is the pattern `src/uat.cts` already argues for with `deferred-items.md`'s in-place `status: resolved`. ## The marker is verdict-preserving and self-invalidating `status:` is never overwritten — writing `resolved` into an unresolved UAT would be a lie in the artifact of record, and the disclosure has to be additive. audit_acknowledged: milestone: v1.0 at: 2026-08-15 status: gaps_found # snapshot of what was true when acknowledged Suppression applies ONLY while the snapshot still matches reality: `status` for seven categories, `question_count` for context questions, and for deferred items a new per-entry `status: acknowledged` distinct from `resolved`, which keeps meaning "actually fixed". Change the artifact and the acknowledgment stops applying, so the item comes back on its own. That is what makes re-opening answer itself with no extra state, and it fails in the safe direction: a stale acknowledgment can never hide a NEW problem. A malformed marker is treated as absent — a bad marker must never silence an item. The check is ONE shared `isAuditItemAcknowledged`, not nine copies. This file has already been through that defect family twice in this PR. ## Observable, not silent `audit-open --json` now reports an `acknowledged` count beside `counts`, so a reviewer can tell a close that is clean because things were fixed from one that is clean because things were silenced. ## Writer New `audit-open acknowledge` verb snapshots current state itself, so the marker is never hand-authored from workflow prose — the gap that left the STATE.md block with no writer, no schema and two conflicting formats. Writes route through the existing path-confinement seam. ## Two deliberate limits, failing closed Heading-delimited deferred entries (#3457) are REFUSED with `unsupported_heading_shape` rather than edited, because mapping a heading entry back to its exact source span is not safely derivable when headless and heading entries interleave in one file. A loud refusal beats a mis-targeted write. A quick task with no summary gets one created to carry the marker, since there is otherwise nowhere to put it. ## Tests Self-invalidation is the important one and is covered per category: acknowledge, then change the status or question count, and the item resurfaces. Also malformed markers not suppressing, `status:` byte-unchanged after acknowledging, the writer refusing a path outside the project, and the four original #3458 scenarios unchanged. Closes #3458 Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * feat(#3458): wire [A] to the acknowledge verb and converge the disclosure table Consumer side of the suppression seam. ## The workflow stops hand-authoring the mechanism `[A]` now calls `audit-open acknowledge` once per open item, then writes the STATE.md `## Deferred Items` table as before. The table stays as a human-readable disclosure; it is no longer the mechanism. That closes the gap where the block had no writer, no schema and no reader — the marker is now written by the tool, which snapshots current state itself. The `[R]` / `[A]` / `[C]` prompt is unchanged, `[C]` still means "Cancel — exit without closing", and no carry-forward option is invented. The all-clear branch now distinguishes a close that is clean because items were FIXED from one that is clean because they were ACKNOWLEDGED, using the `acknowledged.total` count, and carries that into the MILESTONES.md disclosure line beside the existing override count. A clean close that was bought with acknowledgments should say so. ## Format drift resolved Two incompatible `## Deferred Items` shapes shipped simultaneously — 3 columns in the workflow, 4 in the template, with different body lines. Converged on one 5-column shape carrying the source Milestone, since archived items now appear and the archived-milestone disambiguator was previously discarded at write time. The workflow enumerates the categories instead of trailing off in `...`. ## Ack fragment bookkeeping `complete-milestone.md` grows 6,764 bytes (31,228 → 37,992; cap 61,440), covered by a new `tests/emitted-drift-acks/3458-*.json`. `2962-zsh-nomatch-for-glob-portability.json`'s `complete-milestone.md` entry is REMOVED — the no-duplicate-path rule hard-blocks two sources naming one path. That entry is spent: the nullglob shim it acknowledges is present in both `origin/next` and the CI emitted baseline `fd2b97a5`, so its ripple is already absorbed and it can never clear anything again — verified directly, not assumed, and the gate's own message directs deleting spent entries. Its other three files' entries are untouched. `scripts/sync-runtime-launcher.cjs` wanted to rewrite `explore.md` as well — pre-existing drift unrelated to this change, reverted. `complete-milestone.md` still carries exactly one canonical preamble. Docs cover the verb's real flag surface, the marker's verdict-preserving and self-invalidating behavior, and the new `acknowledged` count. A second `Added` changeset covers the verb, since the existing `Fixed` fragment describes only the archived-phase scanning. Closes #3458 Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * fix(#3458): close three blockers in the acknowledgment seam Adversarial review of the seam. Three BLOCKERs, one of which disproves a safety claim I published in the PR body, the changeset and the docs. ## The claim was false; the code is fixed rather than the claim softened I wrote that "a stale acknowledgment can never hide a NEW problem". It could. `context_questions` snapshotted only the question COUNT, so replacing two acknowledged questions with two brand-new blockers kept the item suppressed. `uat_gaps` snapshotted only `status`, so adding five more pending scenarios (`open_scenario_count` 1→6) kept it suppressed. The snapshot now identifies CONTENT, not size: a digest of the whole question set, and a status + open-scenario-count composite. Any edit invalidates. The other seven categories were checked and their single tracked dimension is already the whole story. Both disproofs now resurface the item. ## Writing to the wrong line, and reporting success `acknowledgeDeferredItem` built an unanchored regex and exec'd it over the whole file while match-selection and the ambiguity guard ran over the section body only, so the write landed at the first match ANYWHERE. A file with `# Notes` holding `- Fix the parser` above a `## Deferred Items` section holding the same bullet: the CLI exited 0 saying `acknowledged: true`, injected `status: acknowledged` under `# Notes`, and re-audit still reported the entry open. It corrupted unrelated content, suppressed nothing, and claimed success — and since `--file` is unconstrained the same path could inject into a UAT or VERIFICATION body. Matching is now anchored to the selected section, and the matched span is re-verified against the selected entry before any write; a mismatch refuses with `match_verification_failed` rather than writing. ## Acknowledging todos hid the ones never shown `scanTodos` capped at five files and then checked acknowledgment. With seven todos, acknowledging the five that were LISTED drove `todos: 0`, `has_open_items: false`, and items six and seven never appeared in any later scan. The workflow's own "repeat until no todos items" remedy terminates after one pass. Pre-feature this was unreachable because the count was pinned at five. That is silent over-suppression — the exact direction this PR exists to remove. Acknowledged items are now filtered BEFORE the display cap, so unacknowledged todos beyond it still drive the count. ## The [A] branch could not fail closed Every acknowledge call sat in a `cmd | while read` pipeline with no status accumulation, so any refusal was discarded and the close proceeded as `override_closeout`. Separately, `io.output` swaps payloads over 50000 chars for an `@file:<path>` sentinel — every `jq` would then fail, every loop body run zero times, nothing be suppressed, and the close happen anyway. Both closed: failures accumulate across all invocations and halt before close, and the sentinel is dereferenced using the same pattern `verify_readiness` already uses for `INIT_MANAGER`. Quoting was verified sound by the review and is left alone. ## Also Suppression is now visible in the human report, not only `--json` — the "clean because fixed vs clean because silenced" distinction was promised for the surface an operator actually reads. The CRLF-preservation branches in the writer were dead: every `.md` write goes through `_normalizeMd`, which normalizes line endings and blank lines whatever the writer does. Deleted and documented rather than left as code that cannot run. ## Why these shipped The review named it exactly: there was no coverage for `unsupported_heading_shape`, `ambiguous`, `not_found`, duplicate-text mis-targeting, todos beyond the cap, or CRLF. All are now tested, alongside both snapshot disproofs and the mixed-section fixture. Closes #3458 Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * test(#3458): align the items-open footer wording with its assertion Remote runner red on one test: the items-open footer must match `/previously acknowledged item/i`. The disclosure was NOT missing — the items-open branch already printed "N additional items previously acknowledged and still suppressed." The word order simply did not match the regex the test in the same change asserts. A wording mismatch between my own test and my own implementation, not a behavior gap. Reworded to "N previously acknowledged items also suppressed above the M open items", which satisfies the assertion and states the relationship between the two counts more plainly than the original did. Swept `formatAuditReport` for other branches that could skip the tally: the only early return is the all-clear path, which already discloses it. `scan_error` sentinels are filtered per category and excluded from `counts.total`, so an all-error project falls through to that same branch. No inconsistency remains. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * fix(#3458): splice by carried span, digest the untruncated question set Security review of the writer. Both findings are the same shape, and both are cases where an earlier fix of mine was incomplete in the same direction: a value derived for DISPLAY was reused for an IDENTITY or LOCATION decision. ## Writing to the wrong entry, again The previous fix anchored matching to the `## Deferred Items` SECTION but still re-found the entry inside it with an unanchored regex, so the write landed at the first SUBSTRING occurrence rather than the entry's own span. The `match_verification_failed` guard could not catch it, because the mis-targeted span is byte-identical to the target. Probe-confirmed, in a cloned repo's own artifact: - CRITICAL unfixed auth bypass see also: - minor typo - minor typo Acknowledging "minor typo" appended `status: acknowledged` into the CRITICAL entry, suppressing it at every future close, while the typo stayed open — exit 0, `"acknowledged": true`. A variant where the target text appears inside unrelated prose split that line mid-sentence, acknowledged nothing, and still exited 0, so the workflow's `ACK_FAILURES` halt never fired. Fixed structurally rather than with a better regex: `splitGapsEntriesWithSpans` carries each entry's own character span out of the splitter, and the write splices by that recorded span. The location is already known at selection time — re-deriving it by searching was the entire defect class. Added as a sibling so `splitGapsEntries`' three existing callers are untouched. With index-splicing, `match_verification_failed` becomes a genuine independent cross-check instead of a guard that could never fire. ## The digest was blind past the third question `deriveOpenQuestions` truncated to three questions, and clamped each to 200 chars, BEFORE the digest hashed it — so the snapshot could not see the fourth and later. Ship three innocuous questions, acknowledge, then add real blockers, and they are permanently invisible: measured `open=0, acknowledged=1`, report "All artifact types clear." That is the same self-invalidation property this digest was added to guarantee one revision ago. The digest now covers the untruncated list; truncation is display-only. Found while fixing it: the previous digest joined on a literal raw NUL byte embedded in the source — collisions are constructible, and reachable through attacker-controlled YAML `\x00` escapes. Verified both ways. Replaced with a length-prefixed encoding so no two question sets can collide by concatenation. ## Sweep Because this is the third incomplete fix on this seam, every identity and location derivation was swept for the display-vs-identity confusion: uat_gaps uses status plus a full-content count, the other seven categories use a scalar status or presence, the deferred `--text` identity is never truncated, and all five flat categories resolve their file by path rather than by content search. No further instances. Closes #3458 Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * test(#3458): correct two assertions that over-reached the measured behavior Remote runner red on two of the F1 tests. The source is correct — reproduced both fixtures against the built CLI — and both failures were bugs in the assertions I wrote. `src/` is untouched by this commit. The first is worth recording. It computed the CRITICAL entry's block as content.slice(content.indexOf('- CRITICAL'), content.indexOf('- minor typo')) and `indexOf` found the FIRST SUBSTRING occurrence, which lives inside that entry's own continuation line ` see also: - minor typo`. The block was truncated mid-line, so the assertion could never match. The test committed the exact first-substring-match mistake it exists to catch, one revision after that mistake was fixed in the source. The second asserted `deferred_items === 0` after acknowledging the typo entry, but the decoy `- Note: reference - minor typo elsewhere, ignore` is itself an open entry and was never acknowledged, so the correct count is 1. It now also asserts WHICH item remains open — that is what actually proves the right entry was suppressed, and the original assertion would have passed even if both had been silenced. Both now derive their expectations from measured CLI output. A comment records that the write seam normalizes markdown (`_normalizeMd` inserts a blank line before a list item following a non-list line) so the inserted line is not later mistaken for a regression; that is repo-wide behavior for every `.md` write through the single write projection, not something this change should diverge from. Root cause of both: the previous two dispatches verified behavior with direct CLI probes but never executed the test file, so assertions could over-reach what had actually been measured. Every other assertion added in those two commits has since been re-derived from real output; no further mismatches.
