abf3cf7c25 fix(#3458): scan archived milestone phases, and make [A] Acknowledge actually suppress (#3555)
* 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.

* 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.

* 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.

* 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.

* 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

* 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.

* 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.

* 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.

* 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

* 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.

636ec92107 refactor(#3185): phase enumeration has one owner and a decidable scope (#3222)
* test(#3185): failing-first phase-enumeration single-owner suite

Covers the enumeration rows with direct code evidence: 999.* backlog dirs
listed by progress/stats, the phase-0 sentinel divergence, the #1324
letter-prefixed-decimal negative space, and the destructive-path find —
cmdPhasesClear carries a fifth sentinel copy (/^999(?:\.|$)/) that excludes
999 but not 0, so a 0-* directory roadmap.analyze preserves is deleted there.

Also covers the pass-all degrade, which is where the defect actually lives:
when the milestone window declares no phases the filter becomes a literal
() => true and its heading-side sentinel exclusion is unreachable. A fixture
carrying phase headings keeps the filter active and never reaches that path.

Named for the derivation, not a module: the suite drives commands, phase,
milestone, workstream-inventory and state, and both the phase and
phase-locator buckets are already at the per-module test-file cap.

Committed alone so the remote runner records the failure before the fix.

* refactor(#3185): phase enumeration has one owner and a decidable scope

Adds phase-locator.cts::listMilestonePhaseDirs as the single canonical owner
of "which phase directories belong to the current milestone". It applies the
milestone window AND the sentinel filter and returns a ScopedResult, so a
caller can tell a genuinely-empty milestone from an enumeration that could
not be scoped.

The sentinel test now runs against DIRECTORY NAMES and is unconditional.
getMilestonePhaseFilter excludes sentinels from its ROADMAP heading set, but
degrades to a literal () => true pass-all predicate when that set is empty --
at which point the heading set is never consulted and its sentinel exclusion
is unreachable exactly when it is needed. That degrade is the #3167 path, and
it is why stats already used the filter and still listed backlog directories.
The narrowing is sentinel-only: pass-all stays over-inclusive otherwise.

Sentinel copies deleted, canonical isSentinelPhaseId adopted:
  - cmdRoadmapAnalyze's local closure (parseInt === 0 || === 999), 2 call sites
  - cmdPhasesClear's /^999(?:\.|$)/ -- the DESTRUCTIVE path, which excluded
    999 but not 0, so a 0-* directory roadmap.analyze preserves was deleted

cmdStats also seeded rows from ROADMAP headings with no sentinel filter, so a
999 heading produced a row with no directory; that seed is filtered now.

cmdPhasesList routes only its ENUMERATION. --phase lookup searches the
physical set (scoping it would report an out-of-window phase as not found) and
--include-archived still merges archived dirs (they are by definition from
other milestones). Both exempt by documented reason, never a file allowlist.

Fixed inline, found while building: isDirInMilestone could not match a #1324
letter-prefixed-decimal directory (P0.0-foundation) to its own Phase P0.0
heading, so stats reported the phase with plans: 0 while its directory held
plan files. Defers to phase-id's extractPhaseToken rather than widening a
fourth bespoke regex; additive, so it can only admit directories.

* refactor(#3185): route the last two enumeration re-derivations

workstream-inventory countRoadmapPhases counted every `Phase` heading across
the whole ROADMAP -- no window, no sentinel filter -- so it counted 999.*
backlog and Phase 0 and spanned every milestone the document ever had. Its own
caller already resolved a currentVersion and passed it to getMilestonePhaseFilter
elsewhere in the same file; this was the sibling copy that never got the fix.

state.cts phaseInventoryProvider enumerated phase dirs with its own
/^(\d+)-(.+)$/ convention regex and neither filter, so a rebuilt STATE.md
inventory carried backlog and sentinel directories as current-milestone phases.
A non-COMPLETE enumeration scope now throws to the outer catch as a real scan
failure rather than reporting a confident undercount, mirroring the per-phase
scanPhasePlans contract beside it.

* refactor(#3185): consolidate 23 sentinel re-derivations onto one predicate

The whole-repo drift guard (ADR-3180 Decision 4a, no file allowlist) found the
sentinel rule re-implemented 23 times across 8 modules, in three regex variants
plus four integer-comparison forms. Most tested 999 only, so Phase 0 slipped
through them while roadmap.analyze and the engine-wide convention (#1580) both
treat 0 and 999 alike. That disagreement is the defect class this epic removes.

All 23 now call phase-id's isSentinelPhaseId (SENTINEL_RANGES [0,999]). Sites:
init recommended-actions and backlog counts, milestone phase scan, the
phase-lifecycle progress table, phase.cts used-number collection and the four
renumber-on-remove guards, roadmap-parser's heading and bullet milestone
counts, roadmap get-phase fallbacks, and state's heading denominator.

Excluding Phase 0 at these sites is a deliberate behavior change and the point
of the consolidation — several carried comments already saying 0 should be
excluded while the literal beside them caught only 999.

Adds scripts/lint-phase-enumeration-drift.cjs, wired into lint:ci. It scans the
whole src/ tree with no file allowlist and reports both shapes: an independent
phases-dir enumeration, and an independent sentinel literal. Exemptions are
function-scoped with a written reason. The guard is comment-aware — its first
pass flagged JSDoc and a comment documenting that the code below uses the
canonical owner, which would have trained readers to exempt prose.

* refactor(#3185): resolve every phases-dir enumeration; drift guard reports zero

Per-site triage of the 31 remaining whole-repo guard hits, applying the rule
generalized from #3183's Amendment 1: a LOOKUP, DIAGNOSTIC, ARCHIVAL or
MUTATION pass wants the physical set; only "which phases belong to this
milestone" wants the scoped set.

Routed (10): init new-milestone phase_dir_count, init milestone-op fallback
count, init manager, init progress, milestone complete stats/dry-run/archive
move, phase complete's next-phase scan, state update-progress, state
frontmatter stats, and uat audit's active set.

Exempt with a written function-scoped reason (never a file allowlist): the
audit/UAT/verification sweeps that deliberately scan every directory to report
gaps, phase create/insert/rename/renumber mutations, single-phase lookups,
roadmap-upgrade's cross-milestone migration, cmdPhasesClear's whole-tree
destructive pass, and the reads that list a phase dir's FILES rather than
enumerating the phases dir at all.

Latent defects fixed by the routing: sentinel directories leaked into
cmdInitNewMilestone's phase_dir_count, cmdMilestoneComplete's stats, dry-run
AND ARCHIVE MOVE, cmdStateUpdateProgress, buildStateFrontmatter and
cmdAuditUat's active set — every one of those hand-rolled an isDirInMilestone
filter with no sentinel exclusion, so `milestone complete` was archiving
backlog directories.

scripts/lint-phase-enumeration-drift.cjs now reports 0 re-derivations and
npm run lint:ci is green.

* docs(#3185): document milestone-scoped enumeration and record ADR Amendment 3

Changeset fragment (Changed), CLI-TOOLS/COMMANDS/USER-GUIDE updates for the
scoped output of progress, stats, phases list, phases clear and milestone
complete, the CONTEXT.md Phase Locator glossary entry naming
listMilestonePhaseDirs, and ADR-3180 Amendment 3.

Amendment 3 records: the SCOPE contract held unchanged; the declared deviation
from Decision 1's provisional signature (the window needs cwd/ws, which the
locked roadmapContent parameter cannot supply); the copy count being a lower
bound for the third consecutive phase (4 scoped vs 54 found); the load-bearing
finding that the sentinel exclusion sat on the heading set and was unreachable
under the pass-all degrade; the two destructive-path defects; and the
generalized exemption rule.

* fix(#3185): wire scope to consumers; revert two wrong routings the suite caught

Review + remote runner findings, all fixed:

The three consumers computed the enumeration scope and threw it away, so
TRUNCATED/UNSCOPED/UNREADABLE collapsed into the same output as COMPLETE --
reproducing this epic's own output-identical-failure defect one layer up.
progress, stats and phases list now emit phase_scope (null on the phases list
--phase lookup path, which performs no enumeration).

Two routings were wrong and the suite proved it:

roadmap-parser's two milestone phase-count scans are reverted to the 999-only
literal. isSentinelPhaseId is BROADER than what it replaced: its legacy branch
runs /^0*(\d+)/ over "00.1", which backtracks to capture 0, so it read #2554's
decimal phase ids as sentinel milestone 0 and stopped counting them.

state.cts phaseInventoryProvider is reverted to the physical disk scan.
`state rebuild` is a RECONCILIATION pass -- scoping it made it throw on healthy
trees whose fixture resolves no window, swallowed the raw readdirSync fault
message #3057 B1 requires verbatim, and stopped it dropping orphan STATE.md
rows, which is the job.

Both are now function-scoped guard exemptions with written reasons, not
silent reverts. This is the consolidation trap named in the epic: a canonical
rule can cover MORE than the copy it replaces, and only real inputs show it.

Adds phases list coverage, a scope-branch test, and a drift-guard unit suite;
backports comment-awareness to the milestone-window and plan-count guards so
all three siblings share one false-positive profile; names #3161 alongside
#3167 in Amendment 3's subsumption record.

* fix(#3185): correct isSentinelPhaseId's decimal-zero misclassification

An isolated security review caught this branch committing the epic's own sin:
the over-broad predicate was worked around at ONE call site and left live at
the destructive ones.

isSentinelPhaseId's legacy branch ran /^0*(\d+)/, which backtracks so any id
whose leading digit run is all zeros before a non-digit captures 0 -- "0.1",
"00.1" and "0.2554" all read as sentinel milestone 0. Two pinned contracts
disagree with that: #2554 requires "00.1" to be counted as a real phase, and
the 999 icebox is a whole reserved milestone so "999.1" must stay sentinel.

The rule is asymmetric and now says so explicitly: 999 is sentinel with or
without a decimal part; 0 is sentinel only when bare. A decimal phase under
either is a real phase for 0 and reserved for 999, because 999 reserves a
MILESTONE while 0 reserves a PHASE.

Fixing the owner lets the earlier workaround go: getMilestonePhaseFilter's two
scans route through isSentinelPhaseId again and the guard exemption that
existed only to accommodate the defect is deleted. The state.cts cmdStateRebuild
exemption stays -- that one is a genuine reconciliation-wants-the-physical-set
case.

Also corrects tests/adr-612-bracket-grammar.test.cjs, which asserted
isSentinelPhaseId('0.1') === true and so had encoded the defect as expected
behavior.

* fix(#3185): keep isSentinelPhaseId's semantics — 0.x is layered, not wrong

Reverts the previous commit. The remote suite failed six tests proving it
wrong, and the reason is the sharpest finding of this phase.

An isolated security review observed that isSentinelPhaseId reads 0.1 and 00.1
as sentinel milestone 0 and judged that a defect against #2554. Correcting the
canonical predicate broke #2949. Both contracts are pinned and both are right,
because they ask different questions:

  #2554  is this dir part of the current milestone's phase SET?  -> count 00.1
  #2949  must this phase COMPLETE before the milestone closes?   -> 0.x sentinel

No single global predicate answers both. isSentinelPhaseId keeps its semantics
(0.x IS a sentinel, #2949), and the milestone-window layer keeps a narrower
999-only rule (#2554) as a function-scoped guard exemption with a written
reason — not a second silent copy.

That corrects how Decision 1 reads: "one owner per derivation" governs who
computes an answer, not how many questions share it. An over-broad canonical
rule is as much a defect as a divergent copy and fails worse, because it looks
like consolidation. Recorded in Amendment 3 as the lesson for Phases 4 and 5.

Where a review's inference about intent conflicts with a pinned contract, the
pinned contract wins; the finding is adjudicated, not fixed.

The boundary tables in the enumeration suite are corrected to assert 0.x IS a
sentinel, with the layering explained.

342590c70e refactor(#3184): milestone windowing has one owner and a decidable failure signal (#3209)
* test(#3184): failing-first milestone-window single-owner suite

Covers the 50 input classes in the phase test matrix: scope classification
(genuinely-empty vs truncated vs unscoped vs unreadable), the section-end
owner's level boundaries, consumer-output identity per ADR-3180 Decision 4(c),
the milestone.complete refusal with negative proof that no directory moved,
the version-token boundary defect, drift-guard behavior, and three fast-check
properties over document-shaped generators.

Committed alone so the remote runner records the failure before the fix lands.

* refactor(#3184): milestone windowing routes through one owner

Three copies of the milestone section-end walk lived in roadmap-parser.cts —
two distinct computeSectionEnd function nodes plus an inline third in
getMilestonePhaseFilter's versionOverride branch. computeMilestoneSectionEnd is
now the sole owner and the other two are deleted, not kept in sync by comment.

The whole-repo drift guard found what the epic did not: state.cts held three
more re-derivations of the same vocabulary — two byte-identical milestone
bounding checks carrying a defect neither reported copy has (no boundary after
the version token, so v2.0 matched inside v2.0.1), and a milestone-sectioning
predicate. All three route through the owner now.

A composition-level duplicate appeared inside this change's own first pass:
getMilestonePhaseFilter and cmdMilestoneComplete each re-assembled a window out
of the owner's primitives, and had already diverged on whether to skip a closed
milestone heading. sliceMilestoneWindow is the one composition.

Windows now carry the ADR-3180 SCOPE discriminator, so a truncated window is
distinguishable from a genuinely empty milestone — those were output-identical,
which is the whole failure class. roadmap analyze emits it (#3165), and
milestone complete refuses to archive on anything but COMPLETE rather than
pass-all moving every phase directory on disk (#3166). The pass-all degrade is
preserved where its premise holds: making the filter deny-all would trade a
silent over-inclusive answer for a silent under-inclusive one on the read paths
that count with it.

extractCurrentMilestone keeps its signature — 200+ affected symbols across 41
files and 25 process flows — and is a one-line wrapper over the scoped owner.

* fix(#3184): fence-aware phase detection and one heading-selection owner

Review fixes from the two orthogonal passes.

The blocker: hasPhaseEntries matched ATX phase headings fence-aware via
tokenizeHeadings but tested the #2199 bullet form against un-stripped markdown,
so a fenced EXAMPLE of the bullet syntax counted as a real phase. A genuinely
empty milestone then classified TRUNCATED and milestone complete refused a
legitimate archive — a false positive in the destructive direction, worse than
the defect this phase set out to fix. Both that path and getMilestonePhaseFilter
own pre-existing bullet scan now run on stripFencedCode, since leaving one meant
the owner file gave two different answers to the same question.

The selection rule — locate, prefer the non-closed heading, else the first — had
been written three more times inside the file whose thesis is single ownership.
selectMilestoneHeading owns it; all three sites route through it. The copies were
behaviorally identical, so this is de-duplication with no observable change,
verified by probing that all three paths select the same heading.

roadmap analyze emitting a scope no consumer read left #3165's actual symptom
alive, so Route 0 in next.md now treats a non-complete scope as scan-failed
rather than as a clean empty scan, and the ADR amendment no longer overstates
what shipped.

Also: the scope refusal moved above the archive-directory create, so a refusal
leaves nothing on disk; the versionOverride comment names all four consumers;
COMMANDS.md documents the new guard beside its sibling.

* test(#2658): exclude the changelog from the malformed-path scan

The gate walks every emitted .md/.js/.cjs file in an installed tree and asserts
none contains `.claude/.trae/rules` or `.trae/.trae/rules`. CHANGELOG.md ships
into that tree, and its #2658 entry quotes both malformed paths while describing
the fix that removed them — so the release note documenting the fix trips the
fix's own regression test. Red on next before this branch.

The installer is correct: a probe over a real --trae --local install found 621
emitted files, exactly one hit, and it was gsd-core/CHANGELOG.md. The scan scope
was the defect, not the product.

Excluded by exact relative path rather than by loosening the patterns or skipping
all markdown — the emitted agent and command markdown is precisely what #2658 was
about, so the gate stays strong everywhere it matters.

* test(#3184): regenerate install-tree fixtures for the shared drift scanner

scripts/lib/ ships in the npm package and installer, so extracting the shared
tree-walk into scripts/lib/drift-scan.cjs adds one path to every runtime's
install tree. Regenerated via npm run gen:install-tree; the delta is exactly
that one path per fixture.

The two drift guards themselves do not ship (scripts/lint-*.cjs is excluded),
so only the extracted library moves. This matches the existing
scripts/lib/allowlist-ratchet.cjs precedent, which is likewise a lint-only
helper carried in the shipped tree.

* fix(#3184): restore the #730 sub-milestone boundary and narrow the refusal

The remote runner caught two regressions this branch introduced. Both were mine,
and neither review pass found them — only running the existing suite did.

The version-token boundary. I replaced locateMilestoneHeadings' \b with
(?![\w.-]), reasoning that v2.0 matching inside v2.0.1 was the same defect #2562
fixed in isMilestoneShippedInRoadmap. It is not the same question. A milestone
state of v8.0 legitimately selects the '## v8.0-B' sub-milestone section over a
closed v8.0-A sibling (#730), and \b is what allows it while the stricter
boundary forbids it — nine tests in roadmap-phase-fallback said so. Reverted to
\b; the state.cts consolidation is now a straight merge with no behavior change,
and the v2.0/v2.0.1 ambiguity is left exactly as it was. The ADR amendment and
the design doc no longer claim otherwise.

The refusal scope. I refused whenever the window was not COMPLETE, but #3166 is
about the TRUNCATED window specifically — the heading is found and the section
closes before the phase region, so pass-all archives everything. UNREADABLE and
UNSCOPED are pre-existing, legitimately handled states, and refusing on them
broke 'handles missing ROADMAP.md gracefully' and three archive tests. Narrowed
to TRUNCATED; docs corrected to match.

One of the new tests was also wrong: its fixture gave the shipped and current
milestones' phases the same numeric id, and the filter matches on that id, so it
could not have distinguished the two windows. Fixture corrected to exercise what
it claims to.

* fix(#3184): enumerate drift-scan.cjs for uninstall

The installer copies scripts/lib/ wholesale, but uninstall removes an explicit
set — deliberately, so a user's own helpers in that directory survive. The
extracted drift-scan.cjs was copied in and never enumerated, so it outlived
uninstall, left the directory non-empty, and the rmdir that follows failed.

Added to GSD_SCRIPTS_LIB_FILES, following allowlist-ratchet.cjs, which is
likewise a lint-only helper that ships there and is enumerated. Verified with a
real install-then-uninstall into a temp target: scripts/lib/ held exactly the
three GSD files and was gone afterwards.

* test(#3184): assert install and uninstall agree on scripts/lib and scripts/changeset

Found while shipping this phase, and fixed here rather than noted.

install() copies scripts/lib/ and scripts/changeset/ into the target WHOLESALE —
the comment at the copy site literally says "and any future lib helpers".
uninstall() removes them by hardcoded enumeration, deliberately, so a user's own
helpers in those directories survive. A wholesale writer paired with an
enumerated remover cannot stay in sync by construction: any file added to either
directory ships to every user and is then orphaned in their repo forever, since
it survives uninstall, leaves the directory non-empty, and the rmdir that follows
fails. Nothing reported this. 31,225 tests were green over it.

That is the same divergence class this epic exists to delete, sitting in the
installer, so it gets the same remedy CLAUDE.md prescribes for it: a parity
assertion that fails the moment the two surfaces disagree. The test compares each
directory's real contents against its enumeration and names the offending file
plus the constant to add it to.

Both enumerations are hoisted to module scope and exported, so the test asserts
on the actual arrays rather than pattern-matching the installer's source — no
allow-test-rule annotation needed. Proven non-vacuous both ways: empty diff on
the current tree, correct report when an unenumerated file is injected.

scripts/changeset/ turned out to carry the identical defect and is covered too.

343835facc refactor(#3183): route live-plan counting through scanPhasePlans (#3199)
* refactor(#3183): route live-plan counting through scanPhasePlans

scanPhasePlans becomes the sole owner of the live-plan derivation. Twenty-one
independent re-derivations across seven modules now route through it, and
scripts/lint-plan-count-drift.cjs reports zero, scanning the whole repo rather
than an allowlist (ADR-3180 Decision 4a).

The epic scoped this at three copies. A whole-repo guard found twenty-six sites
across nine files, so Phase 1 absorbs every live-plan re-derivation and Phase 3
narrows to window plus sentinel enumeration.

Two sites are exempt with a documented reason rather than a bare allowlist:
audit.cts scans one quick task's own directory for a single completion record,
and gsd2-import.cts reads a foreign GSD-2 tasks/ layout during a one-time
import. Neither is a phase directory.

scanPhasePlans gains allPlanFiles (pre-supersession) alongside planFiles so one
owner answers both questions: verify.cts's numbering-gap check wants every plan
on disk, its pairing check wants the live set. Both fields are additive.

Highest-severity fix: cmdPhasePlanIndex, which feeds execute-phase wave
scheduling, was scheduling status:superseded plans into waves and reporting zero
plans for the post-#3139 nested layout.

filterPlanFiles and filterSummaryFiles are deleted; getPhaseFileStats orphaned
them and only their own tests still called them.

New leaf module src/planning-scope.cts carries the frozen SCOPE discriminator,
with its six-gate ripple closed: gitignore, inventory manifest, INVENTORY.md and
the CONTEXT.md glossary.

The contract held; the phase boundary did not. The whole-repo drift guard found
26 re-derivations across 9 files against the epic's estimate of 3, and
cmdProgressRender re-derives both enumeration and plan counting on adjacent
lines, so DW4 was unsatisfiable within Phase 1's original file scope.

Records the amended scope, scanPhasePlans's new allPlanFiles field,
findOrphanSummaries, the two documented exemptions, the re-derived Tier-2
table, and the describeNonCanonicalPlans trap for later phases.

* fix(#3183): complete the canonical pairing rule and gate the naming diagnostic

The remote runner went red with 13 deterministic failures on both lanes,
and they were right: replacing verify.cts's canonicalPlanStem pairing with
summaryCandidates dropped a case the bespoke rule covered. A plan carrying a
descriptive slug after its id (68-01-scaffolding-PLAN.md) pairs with its
canonical-stem summary (68-01-SUMMARY.md), and summaryCandidates generated no
such candidate, so the plan read unsummarized.

The fix is to complete the one rule rather than restore a second:
summaryCandidates gains a canonical-id candidate, narrowed to fire only when an
id pair was actually extracted. countMatchedSummaries, findUnsummarizedPlans
and findOrphanSummaries all inherit it. The two-plans-one-summary collision
behaviour of the original rule is preserved deliberately and documented in
place.

Second defect, independently root-caused while verifying: routing the #2893
naming diagnostic through scanPhasePlans exposed it to the loose /PLAN/i
fallback, which is correct for counting and wrong for a naming check — a
non-canonically-named file was accepted as a valid plan and the diagnostic
went silent. cmdPhasesList, cmdFindPhase and cmdPhasePlanIndex now intersect
with a strict isCanonicalPlanFile predicate before reporting names.

Same class as the describeNonCanonicalPlans trap already recorded in ADR-3180:
a question about file naming wants the physical, strictly-matched set; only a
question about outstanding work wants the live set.

five of the six .cts ripple gates - gitignore, inventory manifest, INVENTORY.md

* fix(#3183): replace the plan-count drift detector with a literal tokenizer

CodeQL reported 4 high-severity js/redos alerts on REGEX_LITERAL_MD_RE, the
backtracking regex that finds "a regex literal mentioning PLAN/SUMMARY and an
escaped \.md". Five review rounds found it had two defects, not one:

  - EXPONENTIAL, then CUBIC. Its "any char" atom `(?:\\.|[^/\r\n])` let a `\.`
    pair be consumed either as one escape or as two class characters, which is
    exponential backtracking: 27,464ms on `"/\.mdplan" + "\.".repeat(28) + "X"`.
    Excluding `\` from the class killed that but left a cubic path — 23ms at
    N=200, 172ms at N=400, 1362ms at N=800 on `"/" + "PLAN\.md".repeat(N)` with
    no closing `/`. This guard is the last stage of `npm run lint:ci`, which CI
    runs on fork pull requests, so a crafted src/*.cts could stall the job.
  - A DETECTION HOLE. A character class holding a bare, unescaped `/` — e.g.
    `/SUMMARY[^/]*\.md$/`, an ordinary path-excluding filter — terminated the
    literal at that `/`, so the scan never reached `\.md` and the guard missed
    it entirely. (Classes holding an ESCAPED `\/` were already matched; the
    tests cover those separately as parity, not as regressions.)

Both defects have one root cause: regex-literal grammar — `\x` escapes, and
`/` inside `[...]` not terminating — is not expressible in a backtracking
regex. So the detector is now a tokenizer, not a regex.

readRegexLiteralAt reads the literal at a given `/` in a single left-to-right
pass with no backtracking, treating escapes as two-character units and
suppressing the `/` terminator inside a character class. findRegexLiteralMdMatch
restarts it at every `/` on the line, preserving the old "find anywhere"
behaviour; MAX_REGEX_LITERAL_LEN (400) bounds each read — including the
trailing-flag scan — which keeps the whole-line cost linear.

Results: cubic shape flat at 0.06-0.39ms out to N=3200 (25KB), exponential
shape 0.01ms at 28 reps and 0.00ms at 64, and the bare-`/` class shapes are now
caught. Differential against the old regex over 28,474 lines (those matching
FILENAME_TEST_RE but not PLAN_SUMMARY_LITERAL_RE, across src/tests/scripts/
gsd-core/bin/eslint-rules, excluding 265 lines with >6 backslashes on which the
old regex hangs): 6 differences, all the tokenizer returning the fuller or
newly-correct literal, 0 old-only misses. The `\.md` token stays
case-insensitive, matching the `/i` the old regex carried.

Also closes three holes in the same new file:

  - walk() tested entry.isFile(), false for a symlink, so a symlinked
    src/*.cts was silently unscanned — an evasion of a guard whose stated
    principle (ADR-3180 Decision 4a) is whole-repo discovery with no allowlist.
    It now resolves symlinks, but confined: file links must resolve inside the
    repo root, directory links inside the scanned dir itself. Every sibling
    drift guard in scripts/ uses the Dirent classification and never follows
    links, so following them unconfined would have made this the only linter
    able to read outside the tree — on fork PRs an arbitrary out-of-repo read
    whose matched fragments reach a public CI log. The narrower directory rule
    additionally stops `src/up -> ..` from sweeping the whole repo, and the
    skip list is now checked against resolved paths so `src/g -> ../.git`
    cannot reach .git/** or node_modules/**. Real paths are de-duplicated and
    files reported canonically, so a symlink alias cannot shift which
    FUNCTION_SCOPED_EXEMPTIONS key applies.
  - Both the reported fragment and the reported FILE PATH are attacker-
    controlled source text written straight to a CI log, and git permits
    control bytes in a filename. Both are now escaped — C0/C1/DEL plus the
    bidi and zero-width controls — so a crafted literal or filename cannot
    recolour the log, overwrite a line with CR, or fabricate a line that looks
    like this guard's own success output.

Regression coverage in tests/plan-count-single-owner.test.cjs: a child-process
probe over both pathological shapes (catastrophic backtracking is synchronous
and would freeze the suite rather than fail one test), the bare-`/` class
shapes verified to fail against the parent-commit blob, root-confinement tests
covering the outside-file, outside-directory, cycle, broken-link and duplicate
cases, direct isInsideRoot coverage including the sibling-prefix case that a
bare startsWith would let through, sanitizeForReport coverage, and
limit-1/limit/limit+1 coverage of MAX_REGEX_LITERAL_LEN derived from the
exported constant. The earlier structural assertion was dropped — it checked
for the substring `[^/`, which respelling the class as `[^\r\n/]` defeats
while staying exponential.
