5c7243e54b fix(#3995): derive the review diff base from the phase directory (#4181)
* test(#3995): diff base keys on the phase directory, not commit subjects

All three derivation sites (Tier 3, spawn_reviewer, fallow pre-pass)
must anchor on the phase directory's first commit; the milestone-blind
repro (an archived milestone's same-numbered phase commit capturing
the base) is the failing-first row. #3191/#3503 rows reworked to the
directory-anchor contract; T6 docs-parity forbids any remaining
phase-scope message-grep site.

* fix(#3995): derive the review diff base from the phase directory

A phase number is unique within a milestone, not a repository; the
message grep had no milestone bound and tail -1 deliberately selected
the oldest same-numbered subject, dragging archived milestones phases
into the scope (7 files to 3388 plus the >50 depth downgrade). All
three lockstep sites now anchor on the first commit that added anything
under the phase own directory — the same anchor class
git-base-branch phaseStartCommit uses. ShellCheck baseline gains the
escaped fragment shifted parse signature.

Emitted-Drift-Ack-Growth: code-review.md — phase-directory anchor replaces the message-grep derivation at both sites (#3995)

* chore(#3995): backfill changeset pr number

80d2236ca5 fix(#4112): drop redundant $(( subshell wrapping in pause-work.md Context Detection (#4140)
* test(#4112): add failing-first regression coverage for pause-work.md Context Detection

Extracts and executes the shipped Context Detection bash block to prove the
$(( arithmetic-context misparse (SC1102/SC1106/SC2205) as a hard syntax
error, plus boundary/independence coverage for the phase/spike/sketch/
deliberation resolution the fix must preserve.

* test(#4112): fix false-green regression test — assert dash/sh failure, not bash -n

The prior version asserted bash -n syntax validity and wrapped bash -c
execution, neither of which detects this bug: bash/zsh silently fall back to
a working command-substitution reading of the ambiguous $(( construct, and
bash -n never evaluates arithmetic-context content at parse time. A gsd-test
run against the still-broken file passed 41594/41594 with this test in
place — a false green. POSIX sh/dash does not implement that fallback and
throws a real "Syntax error: Missing '))'", which is what this version
asserts against.

* fix(#4112): remove leaked tool-call tags corrupting the regression test file

A subagent's Write introduced trailing </content>/</invoke> markup at the
end of tests/pause-work-context-detection.test.cjs. gsd-test's own
tests/portability-rule-disable-ban.test.cjs (which parses every test file)
correctly caught this as a parse error. Strips the garbage lines; no
behavioral change.

* fix(#4112): drop redundant $(( subshell wrapping in pause-work.md Context Detection

phase=/spike=/sketch= opened with $((, which POSIX sh/dash parses as
arithmetic expansion and rejects (Syntax error: Missing '))') since the
enclosed text isn't valid arithmetic. bash/zsh silently retry it as command
substitution, which masked the defect there. Dropping the inner grouping
parens (matching the deliberation= line already in the same block) makes
the construct valid under bash, zsh, and dash alike, with identical
fallback-to-empty-string behavior when nothing matches.

Once the surrounding syntax parses, ShellCheck can now also analyze the
inner ls -lt calls it previously couldn't see past the parse failure,
newly surfacing the same pre-existing SC2012 ("use find instead of ls")
suggestion already baselined for the file's other ls usage. Baseline
updated to reflect the true current count; no ls-vs-find behavior change
made, as that is a separate, pre-existing, out-of-scope question.

* fix(#4112): verify shell discrimination instead of trusting the binary name

Code review finding: falling back from dash to sh could silently produce a
non-discriminating test on a host where /bin/sh is bash-compatible (e.g.
macOS) — such a shell never throws on the broken construct either, so the
test would pass whether the bug were present or not. resolvePosixShell now
verifies the candidate actually rejects a known-ambiguous $(( snippet
before using it, and skips with an explicit reason when none does. The
gsd-test Linux bench (dash as /bin/sh) is unaffected either way.

* fix(#4112): route regression test through process-seam, splitLines, cleanup

npm run lint:ci flagged 7 violations gsd-test's node:test run doesn't check:
local/no-adhoc-markdown-parsing (single fence-spanning regex),
local/no-crlf-fragile-split (bare \n split), local/no-unbounded-spawn (x4,
hand-rolled execFileSync with no timeout), and local/no-raw-rmsync-in-tests.
Rewrites the test to route every subprocess call through
tests/helpers/process-seam.cjs's runHook() (bounded by construction),
tests/helpers.cjs's cleanup() for temp-dir removal, and a line-by-line fence
scan using the text-lines.cts splitLines() seam, matching this repo's
established extraction idiom (tests/no-hardcoded-home-gsd-tools.test.cjs).
No behavioral change to what is asserted.

05092ff369 fix(#4113): add no-op to empty then-body in chunked-planning-mode.md's outline resume-check (#4125)
* fix(#4113): add no-op to empty then-body in chunked-planning-mode.md's outline resume-check

The `### 8.5.1 Outline Phase` resume-detection `if` block only contained a
comment in its `then` clause, which is a syntax error under both bash and
zsh if executed literally. The workflow ShellCheck lint added by #4109
already flags this (SC1009/1048/1072/1073/2105) but the findings were
masked by matching entries in the pre-existing-findings baseline; those
five entries are removed here so a regression re-surfaces as a new
failure instead of being silently re-absorbed.

* chore: backfill changeset PR number for #4125

* fix(#4113): fix second empty-then/continue-outside-loop defect surfaced by baseline cleanup

Removing the 5 stale baseline entries for chunked-planning-mode.md in the
prior commit unmasked a second, genuinely separate ShellCheck finding
(SC2105) in a different fenced block of the same file: a bare `continue`
outside any bash loop in the ### 8.5.2 per-plan resume-check. Same root
cause class as the original bug (pseudocode fenced as literal bash) —
fixed the same way, with a `:` no-op preserving the documentation.

e242d85c92 fix(#4109): rewrap unquoted DISPATCH_SLUGS-shaped consumption to survive zsh (#4116)
* test(#4109): add zsh regression coverage for gate-check and invoke_reviewers dispatch

Extends tests/review-plan-coverage-manifest.test.cjs to cover the two
DISPATCH_SLUGS consumption sites the existing #3301 coverage-check tests
don't reach: the write_reviews gate-check block (ALL_LANES_SKIPPED /
TOTAL_LANE_FAILURE counting) and invoke_reviewers' dispatch + join loops.
Both extract the real shipped bash from review.md and run it under bash and
zsh, same convention as the existing coverage-check rows. Expected RED under
zsh pre-fix, GREEN post-fix.

* fix(#4109): rewrap unquoted DISPATCH_SLUGS-shaped consumption to survive zsh

Bash word-splits an unquoted scalar on IFS by default; zsh does not (no
setopt SH_WORD_SPLIT anywhere in these files), so a scalar accumulated from
multiple space-separated tokens and then consumed via bare `for x in $VAR`
collapses onto one bogus iteration under zsh whenever it holds 2+ tokens.

Fixes all four review.md sites reported by #4108/#4109 (invoke_reviewers
dispatch + join loops, the gate-check block, and the #3301 coverage-check
block), plus the identical pattern found by a repo-wide sweep in
complete-milestone.md, code-review.md, pr-branch.md, sync-skills.md, and
execute-phase/steps/per-plan-worktree-gate.md. Each site is rewrapped in
unquoted command substitution (`$(printf '%s' "$VAR")`), which re-splits
identically under both shells regardless of SH_WORD_SPLIT — the same
mechanism that already made the accumulator-building loops in these files
shell-safe.

* test(#4109): warn loudly when the zsh probe fails instead of skipping silently

detectShells() drops the zsh test lane whenever a live zsh probe fails (e.g.
on a CI runner without zsh installed), and a dropped lane reads identically
to a passing one in the suite's own output — exactly the blind spot that let
#4109's bug class ship undetected. Both copies of this helper (this file and
its byte-identical duplicate in review-build-prompt-optional-sections.test.cjs)
now emit a greppable console.warn when the probe fails, so a run without zsh
reads as "zsh coverage unknown" rather than "all lanes green".

* ci(#4109): gate workflows/*.md's embedded bash blocks in lint:ci

Adds scripts/lint-workflow-shellcheck.cjs, wired into npm run lint:ci, so
this bug class can't land undetected a third time. Two independent checks
run over every ```bash block in gsd-core/workflows/**/*.md:

- ShellCheck (new `shellcheck` devDependency, downloads and caches the real
  koalaman/shellcheck binary) catches the general unquoted-expansion/
  word-splitting family in argument position. 212 pre-existing findings
  across the tree are absorbed into scripts/lint-workflow-shellcheck-baseline.json
  (matched on {file, code, message}, not line number, so unrelated edits
  elsewhere in a file can't spuriously un-baseline anything) — fixing all of
  them is out of scope for this issue; only NEW findings fail the build.
- A custom structural check specifically for #4109's own shape: ShellCheck
  does not flag a bare `for x in $VAR` word-list — it treats that as an
  intentional idiom under any ruleset (confirmed empirically). This check
  does, and gates the build on any occurrence, with zero tolerance (no
  baseline) since every known site was already swept and fixed on this
  branch.

* test(#4109): update pr-branch cherry-pick loop test anchor for the zsh fix

extractPickLoop()'s PICK_LOOP_MARKER located the create_pr_branch cherry-pick
loop by the literal substring "for HASH in $INCLUDED_COMMITS", which no
longer appears verbatim after this issue's fix rewrapped that loop in
unquoted command substitution. Updates the anchor (and its error message,
now derived from the same constant instead of duplicating stale text) to the
new literal form. No behavior change to the extraction logic itself.

* test(#4109): cover lint-workflow-shellcheck parsers + add timeout

Adds tests/lint-workflow-shellcheck.test.cjs covering the hand-rolled
parser/logic functions exported by scripts/lint-workflow-shellcheck.cjs
(stripCommandSubstitutions, stripShellComments, substitutePlaceholders,
extractForLoops, findBareForLoopSplits, findingKey, partitionAgainstBaseline)
that shipped with zero coverage — CLAUDE.md requires at least one fast-check
property test for parsers, included here (bare/braced forms always flagged
naming the variable; quoted/substituted/literal forms never are).

Also bounds runShellcheck's subprocess with a 60s timeout: the `shellcheck`
npm package's own API has no timeout option and internally blocks on a
synchronous spawnSync, so this reimplements the binary resolve/download step
via the package's own exported config/download and calls spawnSync directly
with a native timeout. And guards the CLI entry point with
`if (require.main === module)`, matching this repo's sibling dual-purpose
lint scripts — without it, requiring the module for its exported functions
(as the new test file does) also triggered a live ShellCheck run as a side
effect.
