10da377794 fix(#3021): recognize worktree-wf_* branch namespace in all guards (#3109)
* fix(#3021): recognize worktree-wf_* branch namespace in all guards

The Claude-orchestration Workflow backend (#1143) creates per-plan
worktrees on branches named worktree-wf_<runid>-<n>. Four independent
copies of the agent branch allow-list regex (^(worktree-)?agent-...) never
learned this namespace:
- hooks/gsd-worktree-path-guard.js:176 — FAILED OPEN (process.exit(0)),
  silently disabling path containment for exactly the concurrent dispatch
  mode where cross-worktree writes are most likely
- src/worktree-safety.cts:21 — silently dropped cleanup-wave manifest
  entries
- agents/gsd-executor.md:503 — FATAL halt on branch check
- gsd-core/references/worktree-branch-check.md:33 — same FATAL halt

Extended all four to ^((worktree-)?agent-|worktree-wf_)[A-Za-z0-9._/-]+$.
The path guard now correctly blocks cross-worktree writes for Workflow-
backend branches instead of no-op'ing.

b146b82e3c fix(#2868): resume a phase stranded between its last plan and verification (#3041)
* fix(#2868): resume a phase stranded between its last plan and verification

discover_and_group_plans exited unconditionally once every plan was filtered
out, conflating "no plan work left" with "phase fully done". Those differ once a
run can be interrupted between the final wave's SUMMARY and the verify step --
most often by a checkpoint plan that is retired but still writes a SUMMARY. The
result was a phase that looked healthy from every index yet had no
VERIFICATION.md, and whose recommended recovery command provably no-opped,
because the only step that produces the artifact sits ten steps past that exit.

The exit is now conditional. When the verification report is genuinely missing
and no filter is active, the run reports the situation by name and continues at
the tail gates instead of stopping.

Two guards keep the normal paths untouched:

- A filtered run (--gaps-only, or an explicit wave) finding nothing left in its
  own slice says nothing about whether the phase as a whole is done, so it exits
  exactly as before. Without this, --wave 1 on a finished first wave would jump
  to verification with later waves still outstanding.
- A phase that already has its report exits as before too.

The recovered path deliberately keeps the code-review and regression gates. The
manual workaround this replaces skipped both, and that gap is the reason a real
route exists rather than telling users to spawn the verifier by hand.

Also acknowledges the emitted growth of the workflow file. As with #2830 it is
appended to the fragment that already owns that path, since the linter hard-fails
when two acknowledgment sources name the same one.

* fix(#2868): never treat a blocked-and-incomplete phase as finished

Three findings from adversarial review, all fixed.

BLOCKER -- the trigger conflated two different zero-runnable states. This step
now has two skip rules: has_summary (the #2868 target) and, from #2830, a skip
for plans whose blocked_by is non-empty. "All filtered" was therefore reachable
with plans that never ran: plan A halts and is summarized, plan B is blocked by
A and has no summary. The resume path fired, announced "All N plans are
summarized" -- false -- skipped the wave steps so B was never dispatched, and
jumped to the gates. B was silently abandoned, which is the same class of
disappearance #2830 exists to prevent, reintroduced one layer up.

The decision is now an explicit ordered three-way: a filtered run exits
unchanged; any blocked-plan skip reports the phase as stuck on a halt and exits,
routing to resolving the halt rather than to verification; only an
all-summarized, unfiltered phase with a missing report resumes.

MAJOR -- RESUME_TAIL_ONLY was set and never read anywhere in the workflow or its
step fragments. Dead state implying enforcement that did not exist. Removed; the
imperative at the decision point is what actually carries the control flow, so it
now says so plainly.

MAJOR -- the resume path skipped aggregate_results, which is the only step that
runs the secure-phase threats-open gate. A phase with open threats would have
advanced with no warning where a normal run always shows one. The path now
enters at aggregate_results, verified to read only on-disk phase artifacts and
independent queries, so it tolerates having executed no plans this run.

ef823ca9d9 fix(#2830): propagate a halted plan to its transitive dependents (#3038)
* test(#2830): add failing regression tests for halted-plan dependent blocking

Add tests/fix-2830-halted-plan-dependents.test.cjs covering direct,
transitive (2 and 3 hop), and diamond dependents of a halted plan across
both independent "which plans are incomplete" readers (phase-plan-index's
cmdPhasePlanIndex and findPhaseInternal/searchPhaseInDir), the negative
case (an unrelated decoupled plan stays runnable), and a parity check that
the two readers agree. Uses only modules that already exist at this
commit (gsd-tools.cjs via subprocess, the pre-existing phase-locator.cjs)
so the test file loads and runs cleanly on a fresh clone of this exact
commit. These fail against current behavior: neither reader has any
concept of a halted plan or a blocked_by/runnable view yet.

* fix(#2830): a halted plan no longer leaves its dependents on the runnable work list

A plan that reaches a designed stop still writes a SUMMARY, so both
"which plans are incomplete" readers saw it as an ordinary completion and
reported its dependents as ordinary runnable work — never checking
whether an upstream plan had halted rather than finished.

- New `status: halted` frontmatter value, documented in all four SUMMARY
  templates alongside the existing `status: complete`.
- New shared src/plan-dependency-graph.cts: a single computeHaltPropagation
  pass that both phase.cts's cmdPhasePlanIndex (wave-grouping) and
  phase-locator.cts's searchPhaseInDir (the phase-location primitive, ~50
  dependent symbols across 5 command routers) now call, so the
  two-implementation divergence that caused this bug cannot recur. It
  accepts an optional precomputedOrder so cmdPhasePlanIndex — which already
  runs Kahn's algorithm in computeDependencyLevels for wave assignment —
  passes that order straight through instead of a second traversal;
  searchPhaseInDir (no prior traversal) lets the module derive its own.
  The two small duplicated predicates each reader would otherwise carry
  (is this status "halted"?, which summary file matches which plan id?)
  are centralized in the same module as isHaltedStatus/buildSummaryFileIndex.
- Additive fields only: `halted`/`blocked_by`/`runnable` on
  cmdPhasePlanIndex's plans[] and top level, `halted_plans`/`blocked_by`/
  `runnable_plans` on searchPhaseInDir's result. The pre-existing
  `incomplete`/`incomplete_plans` fields are unchanged in meaning and
  membership.
- execute-phase.md's discover_and_group_plans step now also skips any
  plan whose `blocked_by` is non-empty, reporting it by name with its
  blocking chain, in addition to (not instead of) the existing
  has_summary skip rule.

Extends tests/fix-2830-halted-plan-dependents.test.cjs (introduced in the
prior commit) with direct unit coverage of computeHaltPropagation
(including the precomputedOrder call shape) and a fast-check property
test — both only possible once this commit's new module exists.

Closes #2830

* fix(#2830): surface the halt-aware view from init execute-phase

The adopted work made phase-locator compute halted_plans / blocked_by /
runnable_plans, but cmdInitExecutePhase builds its output by explicitly
enumerating fields, so all three were computed and then silently dropped at
the exact consumer the issue names as regressed.

Forwards them additively -- incomplete_plans and incomplete_count keep their
name, type and semantics byte-for-byte -- and adds the same three empty
defaults to the roadmap-only fallback so the shape is consistent in both
branches. Covered by a new test that drives the real CLI end to end rather
than the locator function, since the locator already worked.

* fix(#2830): fail closed on dependency cycles and stop the templates inviting the defect

Three review findings, all fixed:

- BLOCKER (isolated adversarial). Cycle participants never reach indegree 0 in
  the Kahn pass, so they were excluded from the topological order, never visited
  by the forward pass, and vanished from blocked_by entirely -- i.e. reported as
  runnable. The wave-grouping reader hard-fails on a cycle so it never hit this,
  but the phase-location reader does not, so init execute-phase offered a plan
  depending directly on a halted plan. Reproduced, then fixed in the shared
  engine so every consumer is safe regardless of pre-checks: a node absent from
  the order is now blocked with a deterministic, non-empty named cause. A plan
  silently missing from both blocked_by and runnable is the exact disappearance
  this issue exists to prevent.

- MAJOR (isolated adversarial). All four summary templates showed the field as
  an inline comment on the value line. Frontmatter parsing does not strip
  trailing comments, so an executor copying the templates' own presentation
  wrote a halt that parsed as a non-halted string, silently reproducing the
  original bug. Guidance moved off the value line, and the halt predicate now
  tolerates an unquoted trailing comment.

- HARD standards violation. A test regex-matched child-process stderr prose for
  /cycle/i, which CONTRIBUTING bans. Replaced with the structured failure signal
  plus a differential assertion (same fixture without the cycle edge must
  succeed), so it stays cycle-specific without matching prose.

Also folds the duplicated read-summary-and-check-halted wrapper out of both
readers into the shared module -- centralizing only the predicate left the exact
two-copies-that-drift pattern the module exists to prevent -- and commits the
artifact-types documentation for the new status value.

* test(#2830): stop the property generator hanging the whole suite

The remote runner did not fail -- it hung. Two containers sat in this file for
31+ minutes, and an earlier attempt ran 9 hours before I killed it. The runner
passes --test-timeout=0, so nothing ever reaps it: this would have hung CI
indefinitely, not reported a failure.

Root cause: the DAG generator built edges by rejection --

  from: fc.integer({ min: 0, max: n - 1 })
  to:   fc.integer({ min: 0, max: n - 1 })
  .filter(({ from, to }) => from < to)

With n === 1 both integers are forced to 0, so the predicate is unsatisfiable
and fast-check retries value generation forever. n is drawn from 1..12 and
fast-check biases toward boundary values, so n === 1 is reached almost at once.

This also explains why the failing-first run completed normally while the fixed
run hung: before the fix the graph module did not exist, so the property test
threw on import and never reached generation. It only starts hanging once the
code under test works.

Generates the DAG by construction instead -- `to` is drawn strictly above
`from`, with the degenerate single-node case short-circuited to an empty edge
list -- so no rejection sampling is involved. Switches the import to the shared
fast-check setup so the seed and run count are pinned per CONTRIBUTING, and adds
a bounded regression guard that samples the arbitrary directly, so a future
reintroduction fails loudly instead of hanging.

Verified: the file now completes in 2 seconds, 29 tests started and 29 finished,
zero failures, against an indefinite hang before.

* fix(#2830): restore the depends_on display contract and acknowledge the workflow growth

Full-suite run surfaced two things the focused harnesses could not.

1. Regression of a pinned pre-existing contract (#3785). A refactor routed the
   EMITTED depends_on field through the new dependency resolver, which also
   consults the canonical-prefix map. The original consulted the plan map only,
   so a short canonical prefix passed through verbatim -- '24-01' stayed
   '24-01' rather than becoming '24-01-auth-hardening'. The emitted field is a
   DISPLAY mapping, not the DAG resolution, and #3785 pins that. Reverted with
   a comment recording why it must not use the resolver; full resolution is
   still used for the wave DAG and halt propagation, which is what needs it.

2. The workflow file grew 518 bytes without an acknowledgment, from the
   halt-aware skip rule and the widened parse contract. Acknowledged.

Note on where the acknowledgment landed: the guidance is to add a NEW fragment,
but execute-phase.md is already named by an existing fragment and the linter
hard-fails when two ack sources name the same path. Appending to the owning
fragment, following its own established multi-PR pattern, was the only
lint-clean option.

ad3b9ec486 chore(#1671): fragmentize plan-phase.md and repair flag forwarding to the init bundle — Phase 6.2 (#3019)
* chore(#2993): fragmentize plan-phase.md onto the fragment model

Epic #1671 Phase 6.2. plan-phase.md is the largest workflow in the repo and
carried zero markers; it was deferred out of the Phase 3 pilot for two
reasons, both now dead. The 36-byte PRE_PHASE6 headroom was never the
blocker it looked like — fragmentizing is net-negative on host source, so
the trim is what creates the room. The --mvp interleaving was resolved by
measurement in #2992 and no sub-line mechanism is built.

- widen WHEN_VOCABULARY 14 -> 19 via a second coordinated ADR-1671
  amendment: flag:--ingest, flag:--prd, flag:--research-phase,
  flag:--reviews, state:chunked-mode
- state:chunked-mode is `--chunked` OR config workflow.plan_chunked, and
  that disjunction is resolved in the FACT, never in the grammar, so a
  compound condition never becomes an operator
- parse the new flags on the plan-phase route; extract six gated bodies to
  gsd-core/workflows/plan-phase/steps/ behind manifest-gated stubs
- prd-express-path.md was already extracted but read unconditionally; its
  wrapper is now gated, so the existing extraction finally pays off

plan-phase.md 94,483 -> 87,575 bytes (cap 94,519): headroom goes from 36
bytes to 6,944.

Also closes a surfaced docs gap: five real plan-phase flags (--chunked,
--skip-ui, --bounce, --skip-bounce, --granularity) were documented in
neither the argument-hint nor help. Making --chunked load-bearing without
fixing its siblings would leave the defect class half-open.

Refs #2993

* fix(#2993): forward flags to the init bundle so section gating actually fires

Blocker found by the correctness review, confirmed directly, and missed by
both the isolated reviewer and every test in this branch.

Neither workflow forwarded its flags to the init CLI:

  plan-phase.md:71    INIT=$(gsd_run query init.plan-phase "$PHASE" $GRAN_PARAM)
  execute-phase.md:84 INIT=$(gsd_run query init.execute-phase "${PHASE_ARG}")

So every flag: atom was permanently false in production and its section
permanently excluded. For plan-phase that made the PRD express path
UNREACHABLE — a regression, since it was an unconditional read before.
For execute-phase this is PRE-EXISTING: #2932 shipped `flag:--wave` gating
that has never once been true, so `--wave` silently dropped its own
wave-filtering guidance. Fixed here under the no-defer rule.

Why every test missed it: they drive the init CLI directly with flags,
which works. Production goes through the workflow's bash line, which did
not pass them — the exact "assert against the shape production uses" trap
this branch's own test matrix warns about.

- parse and forward --prd/--ingest/--research-phase/--reviews/--chunked
  (plan-phase) and --wave (execute-phase), using the anchored regex idiom
  the neighbouring GRAN_PARAM line already uses
- add a regression guard DERIVED FROM THE MANIFEST: for every flag:--X
  section, the owning workflow's init line must forward --X. It fails
  against the pre-fix files and covers any future atom, rather than
  spot-checking today's six.

Verified through the workflow shape, not the CLI shape: `3 --prd spec.md`
now yields ["prd-express-gate"] (was []), `2 --wave 2` yields
["partial-wave"] (was []).

Refs #2993

* test(#2993): acknowledge the execute-phase ripple and regenerate install-tree fixtures

Remote matrix was red with 46 unique failures, identical on both lanes.
Both causes are mechanical consequences of changing shipped workflow
content, and neither is visible to any local gate.

- emitted-attribution: execute-phase.md grew 163 bytes from the WAVE_PARAM
  forwarding fix and was unacknowledged, while the ack fragment named
  plan-phase.md, which SHRANK and therefore needed no ack at all — a stale
  entry is itself a failure. The reason now names the real ripple.
  The entry had to merge into the existing 2930 fragment: the ack linter
  does unconditional cross-fragment duplicate-key detection with no
  spent/live exception, so a second fragment declaring execute-phase.md
  collides even when the first is already merged and inert. Resolved per
  the linter's own guidance and that file's precedent of appending
  successive ripple reasons to one entry.
- golden-install-tree: tests/fixtures/install-tree/*.json are committed and
  deliberately excluded from the ADR-2719 attribution cutover, so they must
  be regenerated when shipped tree content changes. Regenerated after
  build:lib per the ordering landmine. 19 runtimes each gained exactly the
  six new plan-phase step files; zero paths removed, which is the absolute
  failure shape those fixtures exist to catch.

Refs #2993

* fix(#2993): restore the launcher preamble in an extracted step and follow moved content in its drift guards

Second red run: 26 unique failures, identical on both lanes, in two classes.

RUNTIME BUG (runtime-launcher-parity, 7 failures) — chunked-planning-mode.md
calls gsd_run but carried no canonical launcher preamble, which is what
DEFINES gsd_run(). On any non-Claude runtime that step would fail outright.
The preamble is now copied verbatim from the canonical source of truth,
gsd-core/workflows/_runtime-launcher.snippet.sh, and the fence dedented to
column 0 to match the prd-express-path.md sibling (a list-continuation
indent breaks the byte-equal preamble match). prd-express-path.md already
had a correct one. This is the same defect #2932 hit when it extracted
steps; the parity test caught a real bug, not a stale assertion.

DRIFT GUARDS (plan-phase-drift-guard, issue-2762-plan-reviews-chunked,
skill-frontmatter-contract) — these assert plan-phase.md contains content
this branch moved into step files. Retargeted at where the content now
lives, with the asserted property unchanged; the ALL-RUNTIMES label COUNT
test now reads host + every step file so the count is preserved across the
split rather than reduced. Each retargeted guard was verified to still fail
when its step file is stripped, so none was weakened into vacuity.

No emitted-drift ack was needed: currentSizes() enumerates
gsd-core/workflows/*.md non-recursively, so files under
plan-phase/steps/ are never in the size ratchet's scope.

6c96b13cfe fix(#2639): warn when local is ahead of origin before forking phase branch (#2981)
* test(#2639): add regression for local-ahead-of-origin warning in handle_branching

execute-phase.md's handle_branching forks from origin/$DEFAULT_BRANCH. When
local is ahead (unpushed commits), the phase branch silently misses them.
The test asserts the workflow checks for local-ahead-of-origin and warns.

* fix(#2639): warn when local is ahead of origin before forking phase branch

handle_branching forks the phase branch from origin/$DEFAULT_BRANCH. When
local $DEFAULT_BRANCH is ahead (unpushed commits like plan/research docs),
the fork silently misses those commits. Now a loud WARNING is printed to
stderr naming the commit count and advising the user, matching the existing
uncommitted-changes warning pattern.

* chore(#2639): add changeset fragment

* fix(#2639): condense warning under ADR-857 cap + merge emitted-drift ack

gsd-test gate caught: (1) execute-phase.md exceeded the 93600-byte Phase 6
ceiling — condensed the WARNING from 3 echo lines to 1. (2) emitted-attribution
flagged the growth without an ack — merged into the existing #2930 ack fragment
(execute-phase.md was already acked there; can't have two acks for the same path).

* fix(#2639): condense warning further to clear the 93400 comfortable-margin gate

The ADR-857 Phase 6 test has two assertions: <93600 (hard ceiling) and
<=93400 (comfortable margin). Condensed from 3 lines to 2 to fit under
93400 (now 93369).

640eaee16e chore(#2930): fragmentize execute-phase.md and prove per-runtime composed emission (#2972)
* feat(#2930): fragmentize plan-phase.md workflow into per-runtime-composed sections

Adds src/workflow-fragments.cts (in-file <!-- gsd:section --> marker
parser/composer, ADR-1671 epic #1671 Phase 3), wires it into
bin/install.js's copyWithPathReplacement emission path, and pilots the
marker grammar on gsd-core/workflows/plan-phase.md.

Bookkeeping ripple for the new src/*.cts module: .gitignore,
eslint.config.mjs, docs/INVENTORY.md + docs/INVENTORY-MANIFEST.json,
and a CONTEXT.md glossary entry. Amends ADR-1671 with open questions 1
and 2 resolutions and records the closed when= applicability grammar.
Adds docs/reference/workflow-fragments.md and an ARCHITECTURE.md
section documenting the marker authoring model.

* fix(#2930): put allow-test-rule issue ref on the same line as the marker

lint-allow-test-rule-refs.cjs requires the #NNN issue reference on the
same source line as `allow-test-rule:`; it was one line below and read
as an unreferenced novel exemption.

* docs(#2930): link the orphaned gate-predicates reference from the docs index

Found while adding the workflow-fragments reference doc: docs/reference/gate-predicates.md
shipped without an entry in docs/README.md, so it was unreachable from the docs index.

* fix(#2930): scope composition to workflows, add typed failure reasons

Review findings from two orthogonal passes:

- Scope composeWorkflow to gsd-core/workflows/ only. It previously ran on
  every .md the installer copied, so a future agent/command/reference doc
  documenting the marker syntax with an unfenced example would have been
  mis-parsed and silently stripped — a lossy drop the phase forbids.
- Add a frozen REASON enum; failures attach a typed .reason and tests assert
  on it instead of matching free-form message text (CONTRIBUTING.md:635-694).
- Derive the property generator's when= values from WHEN_VOCABULARY instead
  of duplicating them (DEFECT.GENERATIVE-FIX).
- Add adversarial parser fixtures: Unicode headings, NUL, U+FFFD, BOM,
  fence-within-fence, tilde and indented fences, lone-CR marker line.
- Document why --mvp is structurally unmarkable: its content is interleaved,
  not sectioned, so the whole-line grammar cannot reach it.

Also fixes two stale tests on this branch, each reproduced on the unmodified
tree before correction.

* fix(#2930): retarget the pilot from plan-phase to execute-phase

The full remote matrix went red on both Linux lanes. Root cause was ours:
tests/phase6-capstone-conformance.test.cjs holds a PRE_PHASE6 ceiling of
94519 bytes for plan-phase.md, asserting an ADR-857 Phase-6 completion
property. That is a third size gate beyond the tier caps and the
differential ratchet, and it left plan-phase.md just 36 bytes of headroom
rather than the 3821 computed from the XL cap. The 330 marker bytes
overran it by 294.

Raising the ceiling is not an option: it is a red line certifying another
ADR's completion. plan-phase.md is reverted to byte-identical origin/next
and the pilot moves to execute-phase.md, which has 728 bytes of headroom
under its own ceiling and lands at 93147 with 3 marker pairs.

The vocabulary narrows to the atoms actually used: always, flag:--wave,
state:gap-closure-phase, state:has-prior-phases.

Recorded in the ADR: every branch the epic names lives in plan-phase.md,
which cannot be fragmentized until caps move from source to emitted bytes.
That is direct evidence for the epic's premise and may reorder phases 3-4.

* chore(#2930): backfill changeset PR number (#2972)

* fix(#2930): make the emission install tests portable on Windows

The windows-latest lane went red on three tests in the new install suite;
Linux was green. Both causes were in the test harness, not the module.

Root normalization: the opencode converter always embeds the install root
forward-slashed, but the tests stripped it with the native-separator string
from mkdtemp. On Windows that never matched, so the root leaked through
unstripped — and because the real and stub install roots have different
prefix lengths, that length difference landed directly in the byte-delta
assertion (344 observed vs 275 expected). Normalize both text and root to
one separator form before stripping.

@-ref resolution: the helper stripped only the @~/ and @$HOME/ forms, so a
Windows absolute ref (@C:/Users/...) fell through and was joined onto the
root, producing ...\@C:\Users\... Strip the @ first, then detect
absoluteness from the token's own shape (POSIX, drive-letter, or UNC) with
no platform branching, so every OS takes the same path.

Neither assertion was weakened; the exact-equality byte check is the point
of the test and still holds.

* docs(#2930): document every REASON member and guard the doc/enum parity

Code review found the reference doc's 'Fails closed' list covering 10 of the
11 frozen REASON members — MALFORMED_ATTRIBUTES (parseAttrs rejects malformed
key="value" syntax) had no bullet, and it is distinct from
UNRECOGNIZED_ATTRIBUTE, which is valid syntax with an unknown key.

Two parallel surfaces sharing one constant with nothing asserting they agree is
the DEFECT.GENERATIVE-FIX class, so the same commit adds the parity assertion:
the test derives the enum side from the built module and the doc side by parsing
the reference page, keyed on the reason IDENTIFIER rather than prose so a
reworded bullet does not break it, and reports set differences in both
directions by name.

Proven non-vacuous: removing the MALFORMED_ATTRIBUTES bullet turns the suite
red naming that exact member; restoring it returns 44/44.
