0xdhx 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)
Emitted-Drift-Ack-Growth: autonomous.md — #4748: canonical `[0-9]+[A-Z]?(\.[0-9]+)*` at the --from/--to/--only extractions plus one comment naming the grammar (249 bytes)
Emitted-Drift-Ack-Growth: plan-review-convergence.md — #4748: canonical `[0-9]+[A-Z]?(\.[0-9]+)*` at the phase extraction plus one comment naming the grammar (160 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.

* test(#4748): use t.after() for the composition test's fixture cleanup

CONTRIBUTING forbids try/finally inside a test body; the per-test cleanup
form is `t.after(() => cleanup(dir))`. Flagged by the filing driver's
test-ruleset gate before the PR was created.

* chore(#4748): set changeset fragment pr to 4768

* chore(#4748): refresh the compact-content benchmark baseline after rebasing onto next

Regenerated with `node scripts/benchmark-compact-content.cjs --write` on the
rebased tree (base 0d6bf19bf); `--check` confirms it matches the live recompute.
Only the execute-phase split and the aggregate totals differ from next's copy.
