* fix(#4830): re-land #4768's letter-suffix phase-id fix and its lint-phase-id-drift ratchets on current next

Commit 740ba0d8a (#4781) removed every change #4768 had merged for #4748:
the first-non-digit split at execute-phase.md's two arithmetic sites, the
init-emitted `padded_phase` the REVIEW.md lookup binds instead of
`printf "%02d"`, the canonical-grammar extractions in autonomous.md and
plan-review-convergence.md, the `.changeset/zesty-wolves-tumble.md`
fragment, and the three lint-phase-id-drift ratchets with their tests.
The guard and the code it guarded left together, so nothing went red.

This is a cherry-pick of 092d9256b onto current `next`, resolved against
the #4683 threat-id fields on execute-phase.md's Parse-JSON line, with the
changeset `pr:` reset to the placeholder and the compact-content benchmark
baseline regenerated against the current base.

(cherry picked from commit 092d9256b8)

Emitted-Drift-Ack-Growth: autonomous.md — restores #4768's canonical-grammar extraction and its explanatory comment for --from/--to/--only
Emitted-Drift-Ack-Growth: execute-phase.md — restores #4768's first-non-digit split at two arithmetic sites and the padded_phase binding for the REVIEW.md lookup
Emitted-Drift-Ack-Growth: plan-review-convergence.md — restores #4768's canonical-grammar phase extraction and its comment

092d9256b8 fix(#4748): carry a letter-suffixed phase id through the seven shell sites that aborted or truncated it (#4768)
* test(#4748): pin the letter-axis defect at the seven shell sites outside #4660's six

Extends tests/nsegment-phase-grammar.test.cjs one class over: for each of the
seven sites the live shell lines are read off disk by anchor and executed in
bash against a letter-suffixed fixture. The four `$((10#$PHASE_INT))` split
sites must yield PHASE_N without a shell error for `03A` / `12A` / `3A` /
`03A.1.2` and the commit-scope ERE they build must match both `feat(3A-01):`
and `feat(03A-1):`; the review-file lookup must bind init's `padded_phase`
rather than re-pad in shell; the `--from`/`--to`/`--only` and
plan-review-convergence extractions must return `12A` / `23A.1.2` (and
`23.1.2`) whole; the legacy normalizer must pad `3A` to `03A` and must not
mangle an already-padded `08`. Every pre-existing shape (`06`, `08.5`,
`23.1.2`, `36.14`) is a regression control.

tests/init.test.cjs asserts `init execute-phase` emits `padded_phase` for a
directory-backed `03A`, a ROADMAP-only `4B` (→ `04B`), the existing ROADMAP
fallback `1` (→ `01`), and `null` when the phase is not found.

Negative control against the unfixed tree: 41 failures in the grammar file,
exactly the "(fails before the fix)" cases and the three derived from them
(scope ERE, three-flag extraction, the `08` octal trap); 2 in init.test.cjs,
both the new assertions. Every regression control already green.

* fix(#4748): carry a letter-suffixed phase id through the seven shell sites that aborted or truncated it

The canonical phase-number grammar (src/phase-id.cts) is digits, an optional
uppercase letter, then dotted segments — `12A`, `3A`, `23A.1.2` are documented
shapes that `init`, `phase-id.cts` and `phase remove` renumbering already
round-trip. Seven shell sites in shipped workflows and references still
assumed digits-and-dots. Four classes, one fix each:

Class 1 — `PHASE_INT=${PHASE_NUMBER%%.*}; $((10#$PHASE_INT))` (execute-phase.md
×2, completion-reconciliation.md, tdd.md). The post-#4619 split stops at the
first DOT, so on `03A` the "integer" is `03A` and bash aborts with `value too
great for base`. Split at the first NON-DIGIT instead (`%%[!0-9]*`): the
integer half is a pure digit run, and the letter rides along in the rest the
way the dotted fraction already did — `03A.1.2` → PHASE_N `3A\.1\.2`, so the
#4003 zero-pad-tolerant scope ERE matches both `feat(3A-01):` and
`feat(03A-1):`. Byte-identical output for every id that worked before.

Class 2 — `PADDED=$(printf "%02d" "${PHASE_NUMBER}")` before the REVIEW.md
lookup (execute-phase.md). `printf` cannot pad a letter id (prints `03`,
exits 1) — and cannot even re-pad an already-padded `08`, which bash reads as
an invalid octal and prints as `00`, so the lookup resolved phases 08 and 09
to `00-REVIEW.md` today. The disk path hands the workflow the directory's
padded number but the ROADMAP fallback hands it the heading's bare one, which
is why the re-pad existed. `cmdInitExecutePhase` now emits `padded_phase`
through `normalizePhaseName`, exactly as the plan-phase and code-review inits
do, and the workflow binds `{padded_phase}` instead of re-deriving.

Class 3 — `grep -oE '[0-9]+\.?[0-9]*'` (autonomous.md `--from`/`--to`/`--only`,
plan-review-convergence.md). Stops at the letter, so `--from 12A` ran from
phase 12 with no error. Now the canonical ERE `[0-9]+[A-Z]?(\.[0-9]+)*`, which
also closes the single-segment dot-axis gap the same shape carried (`23.1.2`
→ `23.1`, #4568's class in a spelling neither lint saw).

Class 4 — the legacy manual normalizer (phase-argument-parsing.md, reached
from mvp-phase.md). Its two branches (`^[0-9]+$`, `^[0-9]+\.[0-9]+$`) left
`12A` unpadded and never padded `3A` to the `03A` a directory carries; its
integer branch also hit the same `printf` octal trap on `08`. One branch for
the whole canonical token now, padding the digit run via `$((10#…))`.
Whether this legacy surface should instead be retired in favour of `init`'s
normalization is the maintainer call the issue names; extending it keeps the
documented contract true either way.

Driven end to end: `init execute-phase 3A` on a fixture with a
`03A-letter-variant/` directory emits `phase_number: "03A"` and now
`padded_phase: "03A"`; on a ROADMAP-only `### Phase 4B:` it emits `"4B"` /
`"04B"`. The issue's own evidence line claimed `padded_phase` was already in
the execute-phase init output — it was not; that key is emitted by the
code-review / plan-phase inits, which is where the claim was read from.

* chore(#4634): extend lint-phase-id-drift with three ratchets for letter-hostile phase-id consumers

The rules that landed with #4619, #4568 and #4660 police grammar MIRRORS —
regexes that describe a phase id. The #4748 sites are CONSUMERS of one, and
every existing rule reported clean on them: the shell-arithmetic rule's
`_INT` escape trusts a NAME the dot-only split did not earn on `03A`; the
`[0-9]+\.?[0-9]*` shape is neither the bounded form the single-segment rule
bans nor the unbounded form the letterless rule inspects; and nothing looked
at `printf "%02d"` at all. Three narrow additions, one per shape:

- findDotOnlyIntegerSplitDrift — `X_INT=${<phase-var>%%.*}`; the safe split
  is `%%[!0-9]*`. Keys on the SOURCE variable being phase-carrying.
- findLooseDottedPhaseRegexDrift — `[0-9]+\.?[0-9]*` / `\d+\.?\d*` on a
  phase-carrying line; the canonical form is `[0-9]+[A-Z]?(\.[0-9]+)*`.
  Disjoint from the two sibling regex rules by construction.
- findShellPhasePrintfPadDrift — `printf "%0Nd" …` whose arguments name a
  phase-carrying, non-`_INT` variable; a pad of an `_INT` via `$((10#…))`
  and a `{padded_phase}` binding are the sanctioned shapes.

Same `<!-- phase-id-owner: … -->` sanction, same scan roots as their nearest
sibling (shell idioms over workflows + references, the regex shape over
workflows + references + agents), same documented limit of a per-line
textual scan. The post-#4619 comment that described the `_INT` convention
as proven by `%%.*` is corrected to name the digit-run split. Confirmed
against the base commit: each rule fires on exactly its own unfixed sites
(2+1+1, 3+1, 1+1) and zero violations remain on the fixed tree.

* chore(#4748): refresh the compact-content benchmark baseline and acknowledge emitted growth

The three top-level workflow files below grew by the letter-aware split, the
canonical extraction ERE, the `{padded_phase}` binding, and the comment lines
that name the grammar each site now honours. The committed compact-content
benchmark moved with them; refreshed with `benchmark-compact-content.cjs
--write` (aggregate reduction 15.47% -> 15.45%).

Emitted-Drift-Ack-Growth: execute-phase.md — #4748: first-non-digit PHASE_INT split at the plan-selection and TDD-gate sites, `{padded_phase}` binding at the REVIEW.md lookup, and the comments naming why (482 bytes)

* fix(#4748): name padded_phase in execute-phase.md's init parse list

A `{field}` token inside a workflow bash block is substituted from the init
JSON only for fields the workflow tells the model to parse. `phase_number`
is on that list; `padded_phase` was not, so the `PADDED="{padded_phase}"`
binding at the review lookup would have been a literal — for every phase,
not only letter ones. Found by the pre-file adversarial review (claim 2, the
author's own named suspicion); the test now asserts the parse list carries
the field beside `phase_number`.

* chore(#4634): key the dot-only split rule on its source and widen the printf rule to any %d form

Two false negatives from the pre-file adversarial review of the three #4748
ratchets: `PHASE_PREFIX=${PHASE_NUMBER%%.*}` escaped the split rule because
the destination did not end in `_INT` (the defect is the split, not the
name it lands in), and `printf '%02d'` / `printf "%2d"` escaped the printf
rule because it required double quotes and the zero flag (`%d` cannot parse
a letter id under any width). Both rules now key on the phase-carrying
SOURCE alone; base-site firing counts are unchanged (2+1+1, 1+1) and the
fixed tree stays at zero. The `[[:digit:]]` spelling and the `/phase/i`
heuristic remain the sibling rules' documented limits.

* test(#4748): compose init's emitted padded_phase through the live REVIEW.md lookup

The Class 2 site is a `{padded_phase}` template token, which no test can
execute as written. This substitutes the value init emits
(`normalizePhaseName`) into the three live lookup lines and runs them
against a fixture, so the emitted value, the binding, the path construction
and the status extraction are exercised together — `03A-REVIEW.md` and
`08-REVIEW.md` each resolve to their own status. Suggested by the resumed
adversarial review pass (claim C).

* test(#4748): move the #4619 and #4003 source-parity pins to the letter-safe split

tests/execute-phase-decimal-arithmetic.test.cjs and
tests/safe-resume-gate-anchoring.test.cjs pin the four Class 1 sites'
snippet byte-for-byte, so the first-non-digit split reddened both in the
whole-suite run (scripts/ci-test-scope.cjs does not select either file for
a workflow edit — the scoped run was green). The pinned snippet is now the
shipped one, and the behavioural half of the #4619 file gains the letter
case (`03A` → `3A`, `23A.1.2` → `23A\.1\.2`) beside its decimal cases.

* chore(#4634): key the dot-only split rule on the _INT destination again, tolerating the quoted spelling

Keying on the source alone (the previous commit's widening, from a review
probe) flags `PARENT_PHASE="${PHASE_NUMBER%%.*}"` in
gap-closure-artifacts.md — a correct derivation that wants everything
before the first dot, letter included. The defect this rule polices is a
dot split INTO the name the shell-arithmetic rule trusts as an integer, so
`_INT` is the discriminator on purpose; the quoted spelling that site uses
is now tolerated so the same shape into an `_INT` cannot hide behind it.
Base-site firing unchanged (2+1+1), zero on the fixed tree, and the
parent-phase line is pinned as a silent case.

48271de43f fix(#4660): widen the 6 shell/markdown phase-id mirrors to the canonical grammar's letter axis (#4744)
* test(#4660): pin the letter-axis parity defect across all 6 shell/markdown phase-id sites

Extends tests/nsegment-phase-grammar.test.cjs (#4568) one axis over: for each
of the six sites, reads the live regex off disk and asserts it agrees with
src/phase-id.cts's PHASE_NUMBER_TOKEN_SOURCE on the letter axis in BOTH
directions — accepts `12A` / `3A` / `03A` / `23A.1.2`, still rejects `3a`,
`3AB`, `A3` and the other canonical-invalid shapes — and that the two
extracting sites return the full letter-suffixed token rather than its digit
prefix (or nothing).

Negative control against the unfixed tree: 22 failures, exactly the
"(fails before the fix)" cases; every reject-parity case already green.

* fix(#4660): widen the 6 shell/markdown phase-id mirrors to the canonical grammar's letter axis

Adds `[A-Z]?` after the leading digit run at all six sites #4568 widened —
the ERE translation of src/phase-id.cts's `\d+[A-Z]?(?:\.\d+)*` — so a
documented, canonical-valid id like `12A` or `23A.1.2` is no longer refused
by the four validating sites (code-review.md, code-review-fix.md,
gsd-code-fixer.md, gsd-code-fixer.compact.md) or truncated to its digit
prefix by the two extracting sites (execute-plan.md's plan-filename grep,
plan-phase.md's --research-phase capture). Behaviour is byte-identical for
every id that matched before; the adjacent comment and error-message text
now names the grammar it mirrors.

Driven: `init code-review 3A` on a fixture with a `03A-slug/` directory and
a `### Phase 3A:` heading emits `padded_phase: "03A"`, which the old regex
rejects and the widened one accepts — nothing upstream of the validator
mangles the id.

At execute-plan.md the trailing `-[0-9]+` is the PLAN number and stays
digit-only; plan and milestone dimensions are out of scope per the brief.
`CASE_FLEXIBLE_PHASE_NUMBER_TOKEN_SOURCE` derives from the canonical source
by a literal `.replaceAll('A-Z', 'A-Za-z')`, so src/phase-id.cts is
deliberately untouched.

* chore(#4634): extend lint-phase-id-drift to ban a letter-less phase-id mirror in workflows/ and agents/

Adds findLetterlessPhaseMirrorDrift — the letter-axis twin of the #4568
single-segment rule — flagging the unbounded-segment shape
`[0-9]+(\.[0-9]+)*` (and its \d / doubled-backslash near-variants) whose
digit run is NOT followed by the `[A-Z]?` class, on any phase-carrying line
across gsd-core/workflows/**/*.md, gsd-core/references/**/*.md and
agents/**/*.md. Sanctioned the same way (`<!-- phase-id-owner: ... -->`),
tolerates the case-flexible `[A-Za-z]?` directory-scanning variant so it
cannot force that separate axis to narrow, and is wired into scanAll.
Confirmed zero violations against the real tree post-#4660 fix, and one
violation when a single site is reverted.

* test(#4568): pin the N-segment phase-grammar defect across all 6 shell/markdown sites

Manually traced against the current tree: the validating regex at
code-review.md rejects a 3-segment id (23.1.2), and execute-plan.md's
extraction truncates a 23.1.2-01-PLAN.md filename down to 1.2-01.

* fix(#4568): widen the phase-number regex to accept N-segment ids at all 6 shell/markdown sites

Widens `?` to `*` on the dotted-segment group at all 6 sites (byte-identical
behavior for 1- and 2-segment ids, character class unchanged): code-review.md,
code-review-fix.md, gsd-code-fixer.md, gsd-code-fixer.compact.md (validating
sites, plus their comment/error-message text), execute-plan.md's plan-filename
extraction, and plan-phase.md's --research-phase flag capture.

Also disambiguates the nsegment-phase-grammar test's plan-phase.md anchor,
which was matching an unrelated earlier `--research-phase` occurrence (line
77's generic-value capture) instead of the targeted site (line 131).

db4d8a9bae fix(#4619): execute-phase computes decimal/N-segment phase numbers without breaking shell arithmetic (#4644)
* fix(#4619): execute-phase computes decimal/N-segment phase numbers without breaking shell arithmetic

$((10#${PHASE_NUMBER})) is a hard bash/zsh syntax error when PHASE_NUMBER is
decimal (01.1, from an inserted phase) or N-segment (23.1.2) — neither is
valid shell-arithmetic syntax at all, and the failed expansion aborts the
rest of the snippet in a non-interactive shell. safe_resume_gate runs
unconditionally before trusting STATE.md or dispatching any executor, so
execute-phase failed at its own gate before the first executor on any
decimal phase, regardless of workflow.tdd_mode. Regression from #4194.

Fixes all 4 sites: safe_resume_gate and the TDD gate in
workflows/execute-phase.md, the completion-signal spot-check fallback in
workflows/execute-phase/steps/completion-reconciliation.md, and the
executor gate validation example in references/tdd.md. Each now zero-strips
only the leading integer segment into a *_INT variable (via %%.* / #
parameter expansion — always valid shell syntax regardless of what follows)
and keeps the remainder as an escaped-dot string for the anchored commit-
scope regex, exactly as issue #4619 verified in both bash and zsh. A plain
integer phase (12, 01) computes byte-identically to before.

* test(#4619): pin the decimal/N-segment fix and characterize the pre-fix bug

Behavioral coverage via real bash execution: the old $((10#01.1)) form
throws (characterizes the bug, matching the issue's own reproduction); the
new form resolves 01.1 -> 1\.1 and 23.1.2 -> 23\.1\.2, unchanged for plain
integers (12 -> 12, 01 -> 1); the resulting anchored ERE matches
feat(01.1-03):/test(1.1-3): and correctly rejects feat(01-03):,
feat(01.2-03):, feat(011-03):, feat(12-03): for a decimal phase — mirroring
issue #4619's own verified table exactly. Updates
safe-resume-gate-anchoring.test.cjs's 4 existing source-text assertions
(one per site) to the new fixed text.

* chore(#4634): refine the shell-arith drift detector to distinguish safe from unsafe arithmetic

With #4619's fix in place, the guard's original "ban $((10#... outright,
match any occurrence" was too blunt: it flagged a comment merely mentioning
the pattern in prose, the now-safe $((10#$PHASE_INT)) arithmetic on an
already-%%.*-stripped integer, and the always-safe plan-id arithmetic
(plan ids are plain integers, never decimal). Refines the detector to skip
full-line comments and to only flag a captured variable/placeholder name
that contains "phase" and does NOT end in _INT/_int — the naming convention
the #4619 fix establishes at all four sites for "already reduced to a safe
integer." A plan-id variable was never phase-number arithmetic in the first
place and is excluded on the same basis.

This closes epic #4634's D6 ("lint-phase-id-drift... passes with no new
exemptions") and D7 ("a decimal and N-segment phase id survive an
end-to-end execute-phase selection without error") for real — the guard now
reports zero violations across all five .cts/.md rules.

* test(#4619): cover the plain-padded-integer near-miss matrix too

Review found the anchored-ERE near-miss coverage only exercised the
decimal case (PHASE_NUMBER=01.1); issue #4619's own worked table also
verifies the plain padded-integer case (01 -> PHASE_N=1) against its own
near-miss set (matches 01-03, rejects 01.1-03/011-03/12-03). Adds the
missing assertion.

* fix(#4619): correct JS backslash-escaping in safe-resume-gate anchoring test

The test's string-literal assertions for the PHASE_FRAC//./\\.} pattern wrote
only 2 backslash characters in JS source, which single-quoted-string parsing
collapses to 1 real backslash at runtime -- but the workflow/reference files
actually contain 2 raw backslash bytes at that position (needed so bash's
${var//pattern/replacement} produces the correct single-backslash output).
Write 4 backslash characters in the JS source at all 4 occurrences so the
runtime string matches the files' real bytes.

* chore(#4619): refresh the committed compact-content benchmark baseline

baseline. Regenerate via `node scripts/benchmark-compact-content.cjs --write`.

* docs(#4619): note the safe_resume_gate arithmetic growth in the test header

The emitted-attribution gate flags execute-phase.md growing 91253 -> 91846
bytes (593 bytes). The growth is the fix: the safe_resume_gate and TDD RED
block now derive PHASE_INT/PHASE_FRAC before computing PHASE_N, so a
decimal/N-segment phase number (e.g. 01.1, 2.3.1) zero-strips its leading
integer segment via base-10 arithmetic instead of forcing the whole value
through $((10#...)) and hitting a hard shell syntax error on the first dot.

A blank line previously separated the Emitted-Drift-Ack-Growth trailer from
the Co-Authored-By trailer below it, which splits git's trailer-block
detection: only the last contiguous non-blank run of Key: Value lines at the
end of a commit message is recognized as trailers, so the growth ack was
silently read as ordinary body text and the differential-attribution gate
failed with the growth unacknowledged. Joining the two trailers into one
contiguous block fixes it.

Emitted-Drift-Ack-Growth: execute-phase.md — adds PHASE_INT/PHASE_FRAC derivation to the safe_resume_gate and TDD RED commit-scope grep so a decimal/N-segment phase number zero-strips its leading integer segment via base-10 arithmetic instead of failing on a non-numeric value (#4619)

* test(#4208): replace chmod-based restore-failure injection with a root-proof git shim

`tests/commit-files-deletion.test.cjs`'s two restore-failure tests simulated
an unwritable index via a `post-index-change` hook running `chmod a-w` on
the git dir. That relies on the OS enforcing the *owner's own* permission
bits against itself, which uid 0 (a routine identity inside this repo's
Docker-based gsd-test benches) does not: every DAC check short-circuits true
for root, so the write the chmod meant to block silently succeeds, the
restore comes back clean, and the disclosure/rollback behavior under test
never actually gets exercised.

This is CLAUDE.md's own named anti-pattern for I/O-failure injection
("Cross-platform test IO-failure injection" — chmod tricks fail under root
Docker/CI). It is confirmed as the actual root cause here, not a production
defect: `src/commands.cts`'s `restoreRemovedEntries`/rollback-disclosure
logic (added by #4253, merged just before this run) was hand-traced and
manually reproduced end to end on an unprivileged workstation against a
freshly built `gsd-core/bin/lib/commands.cjs`, and it already produces
exactly the `staging_failed` + "could not be restored" / "could NOT be
restored during rollback" results both tests assert. The other
`post-index-change`-based tests in this file (a `sleep` to force a timeout;
a real `update-index` to flip a restored entry's mode) are unaffected
because neither depends on a permission check — consistent with only the
two chmod-based tests failing on the real remote run.

Replaces the chmod fixture with a fake `git` placed ahead of the real one on
PATH that fails only `update-index --add --cacheinfo` — the one call the
restore makes — unconditionally, regardless of privilege level. Every other
git invocation execs straight through to the real binary, so the rest of
each scenario (`rm --cached`, the restore's own `ls-files` verification,
etc.) is exercised exactly as before.

* fix(#4619): feed the bash fixture script via stdin, not argv, to fix Windows CI

Passing the script as a `-c "<script>"` argv element made it subject to
Windows' CreateProcess command-line argument encoding, which silently
dropped the escaped-dot backslashes before bash ever saw them (observed on
PR #4644's windows-latest CI shard: `1\.1` came back as `1.1`). Feeding the
same script via stdin instead removes argv entirely from the transport, so
there is nothing for Windows to re-encode. POSIX behavior is unchanged.

5e0a7b1b56 fix(#4433,#4569,#4126): consolidate the phase-identity seam at name-validity, allocation, and branch-slug (#4640)
* fix(#4433): apply the name-validity guard symmetrically to every milestone-name capture

extractMilestoneHeadingName already refused a punctuation-only captured name
(#4134), but its two sibling capture sites in getMilestoneInfo — the
STATE.md-anchored 🚧-bullet match and the no-STATE.md in-progress 🚧-bullet
fallback — skipped straight to a bare truthiness check, so a malformed bullet
whose only content past the version was punctuation passed through as a real
milestone name.

Extracts the existing inline /[\p{L}\p{N}]/u check into a single shared
hasNameableContent predicate and applies it at all three capture sites, so
the guard is one owner rather than a copy that happened to land at only one
of them.

* test(#4433): pin the name-validity guard at all three milestone-name capture sites

Failing-first coverage for the hasNameableContent extraction: a
punctuation-only 🚧-bullet name must not surface as a real milestone name,
either on the STATE.md-anchored path or the no-STATE.md in-progress
fallback, while a real name (including a digits-only one) still resolves
COMPLETE exactly as before.

* fix(#4569): consolidate decimal-phase-number allocation into one function

cmdPhaseInsert allocated its next decimal sub-phase number by scanning only
on-disk phases/ directories and ### Phase N.M: headings, never the roadmap
summary checklist — so a decimal that existed only as a checklist bullet
(no heading yet, no on-disk directory yet) was invisible, and phase insert
could silently reallocate an already-used number. It also always nested one
level deeper under afterPhase, with no way to request a sibling.

cmdPhaseNextDecimal had its own separate, near-identical two-source scan
(missing the checklist source too) — the exact "duplicate implementations
kept in sync instead of deleted" pattern this issue exists to close.

Extracts scanExistingDecimalPhaseNumbers (directories + headings + checklist
bullets, in one place) and migrates both cmdPhaseInsert and
cmdPhaseNextDecimal onto it — deleting cmdPhaseNextDecimal's own copy rather
than patching it in parallel. Adds an allocation: 'nested' | 'sibling'
argument to cmdPhaseInsert (default 'nested', matching every existing
caller's behavior); a top-level phase with no existing decimal segment falls
back to nested since there is no sibling level to join. No CLI flag wires
'sibling' yet — that is a separate, disclosed follow-up.

* test(#4569): pin decimal-allocation coverage across phase insert and next-decimal

Failing-first coverage for scanExistingDecimalPhaseNumbers: a checklist-only
decimal must not be reallocated by phase insert; a decimal present in
heading, checklist, and on-disk directory simultaneously must count once;
an unrelated phase family's checklist bullet must not cross-pollute; and
phase next-decimal (migrated onto the same shared helper) must see a
checklist-only decimal too, closing the same gap in a second command.

* chore(#4634): extend the phase-id drift guard for name-validity and shell arithmetic

The epic's ratchet requirement: lint-phase-id-drift.cjs must cover the two
new predicates this PR introduces, and must also scan shell inside
gsd-core/workflows/**/*.md and gsd-core/references/**/*.md for
integer-coercing phase-number arithmetic ($((10#...)) and friends), which
neither the canonical TypeScript module nor a source-only lint can reach.

Adds findNameValidityDrift (bans re-deriving /[\p{L}\p{N}]/u outside
hasNameableContent's owner file) and findShellPhaseArithDrift +
scanMarkdownShellArith (bans $((10#...)) in workflow/reference markdown,
sanctioned via <!-- phase-id-owner: --> on the preceding line). scanRepo
keeps its existing, narrower contract (src/**/*.cts only) so the
already-passing "the live repo is clean" test is untouched; a new scanAll
merges both for the CLI's full report.

Running the guard directly against this tree correctly reports the 7
pre-existing #4619 shell sites (workflows/execute-phase.md x4,
workflows/execute-phase/steps/completion-reconciliation.md x2,
references/tdd.md x1) as violations — demonstrating the ratchet works, not
fixing them. #4619 is a live regression tracked and fixed separately; this
PR does not touch those markdown files. A characterization test pins the
current count of 7 so a future change to that number is investigated rather
than silently absorbed.

* fix(#4569): wire --sibling through phase insert's CLI so the argument is reachable

cmdPhaseInsert's allocation parameter had no CLI path to 'sibling' — shipped,
untested, unreachable code (code-review finding: a guaranteed surviving
mutant). Adds --sibling to phase insert's argument parsing, threads it
through, and documents the flag in docs/CLI-TOOLS.md.

* test(#4569): exercise --sibling end-to-end through the real CLI

Confirms --sibling joins afterPhase's parent decimal level rather than
nesting, and falls back to nested when afterPhase has no existing decimal
segment (no sibling level to join).

* test(#4634): demonstrate the two new drift detectors end-to-end via a planted violation

The epic asks for the guard to be "demonstrated by watching it go red" on a
reintroduced copy. The two new detectors (name-validity, shell-arith) had
only unit-level fixture tests; mirrors the existing bracket-rule's
planted-violation-in-a-temp-tree test for both, proving they're actually
wired into scanRepo/scanMarkdownShellArith end-to-end, not just correct in
isolation.

Standards review flagged the "walk to nearest preceding non-blank line,

detector functions in a PR whose whole point is eliminating exactly that
pattern. Extracts isSanctionedByPrecedingComment, shared by all four;
behavior-preserving (verified: identical output before/after, same 7 known
#4619 violations, zero token/bracket/name-validity).

* fix(#4126): consolidate branch-name slug substitution into one shared renderer

cmdCommit (commands.cts) and cmdInitExecutePhase (init.cts) each
independently implemented branch-name template substitution, and both
substituted the literal string 'phase' when phase_slug was empty or
undeliverable — producing a non-identifying branch name (gsd/phase-08-phase)
that contradicted the honestly-reported phase_slug: null in the same
payload. Same structural defect as the other three gaps in this epic: two
consumers reimplementing one concept independently instead of sharing an
owner.

Adds renderPhaseBranchName (src/phase-id.cts) as the sole owner: a real slug
substitutes normally; an empty/undeliverable one drops the {slug} token plus
one adjacent separator (collapsing/trimming the result) rather than
substituting a placeholder word, for the shipped default template and any
user-configured shape alike. Both call sites now delegate to it; the old
inline duplicates are deleted, not kept in sync. {project} substitution
stays a separate step in init.cts, unchanged, since it is a config-level
field with its own fallback contract.

Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>

* test(#4126): pin renderPhaseBranchName and both migrated call sites

Property-based coverage for the shared renderer's degrade-path invariant
(output, when non-null, never contains {slug} and never starts/ends with a
separator), plus example coverage for real-slug substitution, empty/null/
non-string slug, token position at either edge, a doubled-separator
template, and the only-{slug} -> null case. One regression test each in
commands.test.cjs and init.test.cjs confirms a phase with no derivable slug
no longer produces a branch name ending in the literal '-phase'.

* fix: route scanExistingDecimalPhaseNumbers through the canonical enumeration owner

Caught by an actual gsd-test run, not a hypothesis: the new decimal-scan
helper (fix(#4569)) enumerated phases/ directories via a raw
fs.readdirSync, which the pre-existing phase-enumeration drift guard
(#3185/#3882) correctly flags as an unsanctioned re-derivation outside its
canonical owner (listAllPhaseDirs / isSentinelPhaseId). Ironic given this
epic's own thesis, and exactly why the guard exists: consolidating one seam
can reintroduce drift in an adjacent one if the new code doesn't route
through what's already there. Migrates the enumeration to listAllPhaseDirs;
identical decimal-detection output for every existing case.

* chore(#4634): extend the drift guard for branch-slug fallback; fix a real regex bug

Adds the fourth detector the epic's ratchet section names ("both
branch-name sites"): bans a `.replace('{slug}', ... || 'phase')` call
outright, sanctioned via renderPhaseBranchName or a dedicated comment.
Wired into scanRepo (no per-file exemption — this is a banned anti-pattern
everywhere, not a grammar with one legitimate owner). Now that #4126's fix
(prior commit) has landed, scanRepo reports zero violations across all four
.cts-scanning rules, restoring the simple "the live repo is clean" assertion
instead of a pinned-known-count characterization.

Also fixes a real bug an actual gsd-test run caught: findNameValidityDrift's
regex didn't tolerate the doubled-backslash template-string form its own
test claimed to cover (0 !== 1) — widened to \{1,2} matching
TOKEN_DRIFT_RE's existing tolerance for the same two forms.

* fix: detectPhaseNumberFromFiles wrongly rejected bare, slug-less phase directories

Caught by an actual gsd-test run on the #4126 regression test, not a
hypothesis: a bare phase directory with no slug remainder (e.g.
.planning/phases/01/) has extractPhaseToken correctly return "01" — which is
simply identical to the directory name in that case, not its no-match
fallback. A stale `token !== phaseDir` check treated that equality as "no
numeric token found" and rejected it regardless, leaving phaseNum null and
silently skipping cmdCommit's phase-branching block entirely (the commit
proceeded on whatever branch was already checked out instead of the
phase branch).

phaseTokenShape.test(normalized) already excludes every genuine non-phase
case on its own: extractPhaseToken's real no-match fallback only fires for a
dirName that doesn't start with a digit or short letter+digit prefix, and
normalizePhaseName's leading-\d+ requirement rejects those regardless. The
equality check was redundant for real rejections and actively wrong for
bare-numeric directories.
