bdfc62889b fix(#3784): read the hybrid Current Plan: N of M shape, keep zero-padding, and name the accepted shapes on failure (#3791)
* fix(state): read the hybrid "Current Plan: N of M" shape

advancePlanCore derived the value FORMAT from the field NAME, so it
handled the legacy pair (`Current Plan` + `Total Plans in Phase`) and the
compound `Plan: N of M`, but not the hybrid of the two: the legacy field
name carrying a compound value with no Total Plans sibling. `legacyTotal`
is null so the legacy branch fell through, and the compound branch reads
the `Plan` field through a `^Plan:`-anchored pattern that never matches
`Current Plan:`. Both produced NaN against a file whose plan numbers are
plainly readable.

The shape is not exotic. An agent wrote it unprompted into a project's
STATE.md, believing it was the parseable form, and every subsequent run
in that project inherited the failure and worked around it by hand.

Track the field name and the value shape separately (`planSourceField`,
`planRawValue`) so write-back targets whichever field the value came
from. The legacy pair still takes precedence when both fields exist, so
a stray "of N" inside Current Plan cannot override an explicit Total
Plans — covered by a new test.

Also replace the caller's catch-all error. It reported "Cannot parse
Current Plan or Total Plans" for ANY transition failure, and named no
accepted shape, so a reader learned neither what failed nor what to
write. It now distinguishes "no result" from "unreadable plan position"
and lists all three shapes. The existing test asserted the literal
"cannot parse"; it now asserts the message names the shapes, which is
the property that makes it actionable.

* fix(state): keep zero-padding when advancing a compound plan value

The compound write-back rewrote only the leading half of "N of M", so a
padded value drifted lopsided: "04 of 06" advanced to "5 of 06". Cosmetic
on its own, but a plan line that looks wrong is one the next writer tidies
by hand, and hand-tidying this particular line is what produced the hybrid
shape the previous commit had to teach the parser to read.

Pad the incremented number to the width it was written with. padStart never
truncates, so a value that outgrows its padding widens correctly: 09 of 12
advances to 10 of 12. Unpadded values are untouched — 2 of 6 still advances
to 3 of 6.

* fix(state): pass a literal field name to the compound write-back

The previous commit passed `planSourceField` — a variable — as the field-name
argument to `stateReplaceField`, which trips the state-write-path drift guard's
`unstripped_content_write` axis (ADR-3408 §8.3(b)). The guard is right to care:
a Title-Case literal cannot collide with a lowercase or snake_case frontmatter
key, so it is safe whatever the content argument is, while a variable could
hold anything and therefore requires its content to be demonstrably
frontmatter-stripped first.

The content argument here IS stripped — `body` is `stripFrontmatter(content)` —
but the guard does a narrow backward scan rather than dataflow tracking, by
design, and the nearest preceding assignment to `body` is another
`stateReplaceField` result. Rather than baseline a bypass or ask a future
reader to re-derive that the invariant holds, dispatch on the discriminator and
pass the literal.

Guard goes from 1 finding to 0; its own 32 tests pass.

* test(#3784): cover the maintainer's AC1 write-back and AC6 reader-anchoring

Triage published six acceptance criteria; two were only half-covered.

AC1 asks that the hybrid write back to the SAME field with padding preserved.
The existing hybrid test used an unpadded value and asserted only `result.data`,
so it proved the parse but never the write. Now asserts the written content is
`05 of 06` on the original field, and that no separate `Plan:` field appears as
a side effect.

AC6 asks that the shared field reader not be loosened. Reading the hybrid is the
transition's job; `stateExtractField('Plan')` is line-anchored and has 13+
callers, so teaching it to match a name merely ENDING in "Plan" would be the
wrong fix and would silently change what those callers read. This holds by
construction here — the reader is untouched — but nothing locked it in. The new
test fails if anyone later reaches for that shortcut.

Also drops the changeset fragment written against the auto-closed PR number.

* fix(#3784): write the advanced plan back to the field it was read from

Review findings 2-6 on #3791 were one defect seen from several angles: the
read path learned the hybrid `Current Plan: N of M` shape, the write path
did not follow it.

- `bumpLeadingNumber` now owns the increment for all three parse branches.
  Only the leading digits belong to this transition; the padding width and
  everything after it (` of M`, and the `\r` of a CRLF file) are the
  author's text and are preserved. The legacy branch wrote `String(newPlan)`,
  which turned `2 of 99` into `3` and `04` into `5`.
- `mutateCurrentPositionForAdvance` takes the plan field NAME. Its plan arm
  only ever looked for `Plan:`, so on a hybrid file the `## Current Position`
  section was never reached; combined with the body-level write being
  single-shot and bold-preferring, a file carrying the field at both sites
  advanced the header and left the section a plan behind. The parameter
  defaults to `Plan`, so the two callers that pass no plan are unchanged.
- Tests: both-sites-advance (fails without the section arm), legacy
  write-back content assertions (the previous test read only `data` and so
  could not see the lossy write), hybrid boundary at limit-1 and limit+1, a
  CRLF fixture, and an fc property pinning the padding-width contract.

Two characterization tests pinned `**Current Plan:** 02` advancing to `3`.
That dropped padding is the defect #3784 reports, so the expectation is
corrected to `03` rather than the fix being narrowed around it.

* fix(#3784): drop the unreachable advance-plan error branch, sync the doc

Findings 1 and 8 on #3791.

The `!resultData` arm could not fire: the transform callback assigns
`resultData` unconditionally, only runs once STATE.md is known to exist (the
missing-file case returns "STATE.md not found" upstream), and every
`advancePlanCore` return path sets `data`. It was a speculative second
failure mode with a message no caller could receive, and the comment beside
it claimed to distinguish two things that were never two. `!resultData`
stays in the condition as a type guard, which is all it ever was.

`docs/json-errors.md:142` quoted the old error literal verbatim and was the
sole occurrence in the tree; it now quotes the emitted one.

* chore(#3784): describe the write-back fix in the changeset

* fix(#3784): anchor the plan grammar and widen the schema row to match

Review round 3 on #3791: B1, B2, M1, M2, M3, M4 and the planSourceField nit.

B1 — `STATE_FIELD_SCHEMA.current_plan.acceptedShapes` widens to
`['N', 'N of M']`, which is what `src/state-md-schema.cts`'s own comment
instructed this PR to do on merge. `'N/M'` stays undeclared so row 23 keeps a
non-vacuous undeclared candidate to probe. Verified `gen-state-md-docs
--check` exits 0 and `--write` rewrites 0 of 6: the generated artifacts do not
surface this row, so there is nothing stale to regenerate.

B2/M4 — the discriminator was `/of\s+(\d+)/`, unanchored, so a total could be
read out of prose. `Current Plan: 4 — blocked on review of 2 PRs` parsed as
`4 of 2`, took the `currentPlan >= totalPlans` branch and WROTE
`Status: Phase complete — ready for verification` into the user's file. Both
shapes are now anchored at the start and every number comes from a capture
group via `planNumberFrom`, which rejects anything past `Number.MAX_SAFE_INTEGER`
rather than letting `data` and the persisted string disagree. Nothing on this
path calls `parseInt` on a raw field value any more.

The grammar keeps a trailing remainder after the total, because
`Plan: 2 of 5 in current phase` is a real tested shape. The refusal comes from
requiring `of <total>` to follow the leading number immediately, not from
forbidding a suffix.

M1 — `bumpLeadingNumber` is total. It returned its input unchanged when there
were no leading digits, so `+2` reported `advanced: true` while writing the
file untouched.

M2 — both section arms use replacer functions. File-derived text was being
spliced into a `String.replace` replacement string, where `$&` / `` $` `` /
`$'` expand: a value of `04 of 06 $&` spliced part of the document into itself.
`stateReplaceField` already used a function; these now agree with it.

M3 — the section arm targets the name the SECTION carries, and the body write
now writes both spellings, each with its own rendering. Keying off the header's
name left the other name stale in both directions: a legacy header beside a
`Current Plan:` section line, and a `**Plan:**` header beside one.

* fix(#3784): derive the shape error from the schema, widen the test coverage

Review round 3 on #3791: B3, m1, m2, m5 and the two test nits.

B3 — the accepted-shape set had two owners: the parser branches and an English
list hand-written beside them in `state.cts`. Nothing coupled them, so adding a
branch left the message stale and removing one left it advertising a shape that
errors, with no test able to see either. The message is now built from
`STATE_FIELD_SCHEMA.current_plan.acceptedShapes`, and the CLI test walks the
schema instead of restating the list. `Plan: N of M` is still spelled out
explicitly because no schema row owns the body-only `Plan` field —
`buildStateFrontmatter` never reads it into frontmatter, so it has no key to
hang a row on.

m1 — the property drove only the pre-existing `**Plan:**` branch, i.e. not the
branch under review. It now drives both compound spellings and ranges past 99
so the width transition is covered by the property rather than one example. A
second property covers the legacy pair's own preservation contract. Both were
mutation-checked: dropping the padStart turns 9 tests red.

m2 — degenerate boundary fixtures around the threshold (`0 of 0` is
phase-complete, not an error; `0 of 3` advances) plus the shapes the anchored
grammar must refuse, including Arabic-Indic digits.

m5 — `docs/json-errors.md` described rather than quoted the message, since it
is now schema-derived and a verbatim quote would be a third owner.

Nits — the CRLF assertion could not see a `\n` at index 0; the
`!/^Plan:/m` presence proxy is now an identity assertion on the whole
`## Current Position` body.

* fix(#3784): give the section plan write its own flag, and stop narrowing what parses

Review round 4 on #3791: Blockers 1-4, Majors 1-2, Minors 1-2.

B1 — the section fallback was guarded by `!mutated`, and `mutated` is
FUNCTION-wide, already set by the phase/status/lastActivity arms that
`advancePlanCore` always populates. A section spelling the field bold or as a
pipe-table row therefore skipped its fallback because an UNRELATED field had
been refreshed, and stayed a plan behind the header — the split-brain document
this arm exists to prevent. The arm now tracks its own `planWritten`.

Worth recording: the reviewer's fixture does not reproduce. The body-level
status write lands on the section's own `Status:` when the document has no
header `Status:`, so `mutated` is still false by the time the plan arm runs and
the fallback fires. The discriminating shape needs a header `Status:` to absorb
that write AND a bold section plan line. The mechanism was right; the example
was not, and the regression test uses the shape that actually fails.

B2 — `fallbackName` chose one name by ternary. In the legacy shape both values
are populated, so it always chose `Current Plan` and a `**Plan:**` section line
— which base did write — got nothing. Each name is now attempted independently
with its own fallback.

B3 — `PLAN_SHAPE_N` was anchored harder than `PLAN_SHAPE_N_OF_M`, so values base
parsed via `parseInt` began to hard-error: `Total Plans in Phase: 5 phases`,
`Current Plan: 3 (blocked)`. #3784's brief puts normalizing plan numbers beyond
this transition's read/write out of scope, so that narrowing was not licensed.
Both grammars now carry the same trailing tolerance. The prose defect stays
closed by the START anchor, not by forbidding suffixes.

Major 1 — the whole-body `Plan` write is scoped to documents that declare a
`Plan` field, instead of firing unconditionally where `stateReplaceField`'s
first match could be prose outside `## Current Position`.

Major 2 — the error message names both `Plan` spellings the parser accepts; it
previously omitted the sibling-paired form, which is the same
message-disagrees-with-parser drift the derivation exists to close.

B4 — the changeset claimed a guarantee B1 broke; it now describes what ships.

Minors — safe-integer boundary coverage at limit-1/limit/limit+1, and the CRLF
comment states the real mechanism (`stateExtractField`'s `(.+)` stops before the
CR; the trailing group is belt-and-braces, not the primary defence).

All three blocker regression tests verified red against the pre-fix source.

* test(#3784): pin the hybrid shape against #3807's ambiguity refusal

#4028 landed `advance-plan`'s multi-`Phase:` refusal on `next` after this
branch's last run, on the same function. The guard sits above the parse, so
a refused document is never parsed and the shape #3784 adds cannot reach the
mutation — but that is a property of source ordering, so assert it as
behaviour instead.

Fail-first proven, not assumed: with `phaseCandidates.length > 1` disabled,
the ambiguous hybrid document advances its FIRST entry's
`Current Plan: 04 of 06` to `05 of 06` and writes it — #3807's exact defect,
reached through #3784's shape. Both tests go red; both go green with the
guard restored.

The control pins the other direction: an unambiguous hybrid section still
advances, and its zero-padding still survives.

* fix(#3784): advance every spelling from its own text, refuse when they disagree

Round 6 review. B1 and M1 are one defect, so they are one fix.

`advancePlanCore` picked one field to parse from, computed `newPlan`, then
wrote BOTH spellings from that field's numbers. Two symptoms:

  B1  With `Plan` as the parse source, `Current Plan` was re-stamped with
      the number just derived from `Plan`. `Current Plan: 7` beside
      `Plan: 2 of 5` silently became `Current Plan: 3` — a value nothing
      derived for that field, no error, no diagnostic.
  M1  With the legacy pair winning, the `Plan:` line was re-rendered from
      a bare `${newPlan} of ${totalPlans}` built out of the sibling field.
      `Plan: 2 of 9` became `3 of 5`; `Plan: 03 of 05` became `4 of 5`.
      The changeset's claim that padding and everything after it survive
      was true only for whichever field happened to be the parse source.

Now: every spelling is advanced from its own raw text via
`bumpLeadingNumber`, so each keeps its own padding, its own total and its
own trailing annotation. Differing TOTALS are preserved, not reconciled —
`Plan: 2 of 9` beside a `Total Plans in Phase: 5` advances to `3 of 9`.

Differing CURRENT numbers are refused, with `reason:
"ambiguous_plan_position"` and both candidates named. Same posture as
#3807's multi-`Phase:` guard one field over: name the conflict, let the
caller resolve it, never pick. The guard sits immediately after the parse,
BEFORE the phase-complete branch — guarding only the normal advance would
let `Current Plan: 7` beside `Plan: 5 of 5` write a terminal "Phase
complete" into a document whose two spellings never agreed.

A field present but unreadable (`Plan: TBD`) is left exactly as authored.
Refusing the whole document because an unrelated line cannot be read would
be a narrowing #3784 does not license; writing a derived number over it is
the fabrication B1 was filed for.

The `planSourceField`/`planRawValue`/`useCompoundFormat` tracking is gone.
It existed only so the write path could ask which field the value came
from, and the write path no longer asks.

M2. The bare `Plan: N` + `Total Plans in Phase: M` shape is dropped. A
revision of this PR added it; base refused it. It cannot be given the
schema-row + forcing-test coupling the other shapes have, because `Plan`
is body-only and `buildStateFrontmatter` never reads it into frontmatter,
so there is no `current_*` key to hang a row on. Parser, the spelling in
`advancePlanShapeError`, and the lockstep test move together — the
invariant is the lockstep, not the length of the list.

N1. The whitespace narrowing (`5phases` no longer parses where `parseInt`
read 5) is documented in the changeset beside the other deliberate
narrowings, rather than loosened. Loosening restores the half-parse this
change exists to remove.

Tests: eight new cases plus a property that crosses the two spellings with
agreeing and disagreeing numbers — the review noted the existing
properties never did. Fail-first proven: restoring the old write path
reddens seven of the eight, both new property arms, and two pre-existing
padding tests.

* fix(#3784): report Current Plan as updated only when it was written

The write became conditional in the previous commit — a `Current Plan:`
that is present but unreadable is left as authored — but the `updated`
push stayed unconditional, so `transitionCore` reported a field it had not
touched. `reconcileReportedFields` would have caught it against the
persisted bytes at the `state.cts` caller, but `transitionCore`'s own
`updated` is consumed directly (milestone-lock, the transition tests) and
has to be true on its own.

Covers the mirror of the unreadable-spelling case: `Current Plan: TBD`
beside a readable `Plan: 2 of 5`, where `Plan` is the parse source and the
legacy field is the one that cannot advance. Fail-first proven.

* test(#3784): account for the new refusal in the output({error}) census

`tests/io.test.cjs`' A3 census asserts the exact population of
`output({error})` call sites in `src/`, per module. The
`ambiguous_plan_position` refusal added a 27th to `state.cts`, so the
census went red at 26/65.

Updated the way #3807 updated it when it added the ambiguous-POSITION
error one line above: bump the count and name the addition inline, so the
next person reads why the number is what it is. The alarm did its job —
it is the only gate that noticed a new user-visible error path had been
introduced.

d24e22b156 enhance(#3912): gsd-tools declares outcomes, pinned at v1 (#3983)
* enhance(#3912): gsd-tools declares outcomes, pinned at v1

ADR-3889 §4. Phase 6 already moved error()'s terminator onto the seam, so what
remained was the declaration — and the pin that makes it invisible today.

The census corrected two documented figures before any code changed.
ERROR_REASON has exactly 25 members (the ADR and epic were right; an earlier
note of mine claiming 23 was wrong and is corrected). And output({error}) is
**64 sites across 9 files, not the 60 ADR-2980 ratified** — the module shape
holds but the total drifted +4: frontmatter 7 not 6, phase 4 not 2, roadmap 3
not 2. That matters because this phase's criterion demands the pin be asserted
over the enumerated population rather than sampled; asserting over a stale 60
would leave four sites unpinned while claiming full coverage, which is the
shape of failure this epic exists to remove.

The issue does not state the fact that shapes the design: output() never
touches the exit code. Confirmed by reading it — it writes fd 1 and returns.
So a declared outcome for those 64 sites had nowhere to be READ. The mapping
was never the work; wiring somewhere for the declaration to land was.

The seam already existed twice over. cli-exit.cts holds two globalThis-Symbol
cells, each because the module is emitted to three locations and a module-level
`let` would let instances disagree, and runMain already maps a code returned by
main(). A third cell inherits that solution. output() records DEGRADED for any
{error} payload — key-order agnostic, which is exactly why the "42 sites"
figure undercounts — and runMain projects the cell only when main() returns
nothing, so an explicit return still wins.

error() maps its reason through a table over the closed 25-member enum, leaving
all 278 call sites untouched; 226 of them pass no reason at all. The version
gate lives in error(), NOT in projectOutcome: registered names are
version-invariant there, so mapping a reason straight through would make USAGE
project to 64 under v1 and break the pin on its first line. projectOutcome is
left exactly as Phase 2 shipped it, DEGRADED's 0/80 asymmetry included.

Proven rather than asserted. v1 is byte-identical across three real CLI paths —
config-get plain, config-get --json-errors, and an output({error}) path —
matching exit code and exact bytes against the pre-change build. Under
GSD_EXIT_CONTRACT=v2 the same commands now exit 66 (CONFIG_KEY_NOT_FOUND ->
NO_INPUT) and 80 (DEGRADED), both looked up through the registry. An
anti-vacuity test pins that v1 and v2 genuinely differ for at least one reason,
because without it a mapping where everything projects to 1 under both versions
would satisfy every other assertion and the declaration would be theatre.

A1 iterates all 25 enum members and A3 asserts over the measured 64-site
population, so a 26th reason or a 65th site fails until it is given a mapping —
the drift guard this phase needs, given ADR-2980's own count had drifted +4
unnoticed.

Verification runs on the remote runner.

Refs #3912

* fix(#3912): the outcome cell must never lower an exit code

The remote run caught a fail-open that this phase introduced, in the phase
whose entire purpose is removing fail-opens.

`state validate --strict` on a missing STATE.md exited **0** where it must exit
1. Mechanism: `runMain` projected the pending outcome whenever `main()` returned
void, and under v1 DEGRADED projects to 0 — so a `process.exitCode` already set
non-zero by the command was clobbered down to success. Confirmed live against a
fixture, before and after.

This refutes a review conclusion recorded earlier in this phase, that the cell
was "fail-closed and can never mask a failure as success". It could, and did.
Recording that plainly so the assumption is not repeated: the cell's danger was
never only that it might add a failure — it was that projecting it
unconditionally overwrites whatever decision came before.

Projection is now guarded: it may set a code only when none is set, and an
already-non-zero exit code always wins. The full precedence — explicit `main()`
return, then an existing non-zero exitCode, then the declared outcome — is
written at the projection site. A regression test drives a void return with a
pre-set non-zero code and a pending DEGRADED, and fails against the pre-fix
build.

The second failure was my test encoding the wrong contract, not a code defect.
It asserted `output({found:false, error: undefined})` records DEGRADED because
the KEY is present. `JSON.stringify` drops undefined, so the payload the user
receives is `{"found":false}` — carrying no error at all, and calling that
degraded would hand back exit 80 under v2 for output that reads as clean. The
discriminator is a serializable error VALUE, not key presence. The test now
pins `{error: undefined}` as explicitly NOT degraded, and the design doc's
wording is tightened to match.

Verification runs on the remote runner.

Refs #3912

* docs(#3912): the versioned exit contract, and a flag defect the docs found

Diataxis pass for Phase 8, plus a real fix that only surfaced because writing
the how-to meant running its own examples.

The docs. ADR-2980's "Revisit if" clause asked for exactly the versioned
projection this phase provides, so it gets an amendment naming #3912 /
ADR-3889 section 4 as that boundary: v1 stays 0 byte-for-byte, v2 projects
DEGRADED to 80. The amendment also records the count drift rather than
restating a stale figure — the ADR ratified 60 output({error}) sites in 9
modules; the AST-measured population is 64 across the same 9 (frontmatter 7
not 6, phase 4 not 2, roadmap 3 not 2). The pin is asserted over the
enumerated 64. json-errors.md gains the outcome-declaration reference,
including the precedence order a review pass got wrong and the suite refuted:
an explicit main() return, then an already-set non-zero process.exitCode, then
the declared outcome. Projection may only ever set a code, never lower one.

A how-to is owed here and is written, not skipped. Under v1 nothing changes,
so the audience is an operator opting into v2 and needing to know what the
codes mean for a CI gate — a migration, which is how-to shaped. It covers
turning v2 on, the code table, why 80 is "ran and reported a condition" rather
than a crash, and how to split a gate that treats any non-zero as fatal. No
tutorial: there is no new entry point to learn, and under the default contract
a reader would be walked through observing nothing.

The defect. Running the how-to's own Step 1 example returned

    $ gsd-tools --exit-contract=v2 state validate --strict
    Error: Unknown command: --exit-contract=v2          (exit 64)

while the same flag trailing the subcommand worked and exited 80. The flag
half-worked, by argv position. resolveContractVersion scans argv
non-destructively, so the token survived into the dispatcher, which treats
argv[2] as the command name. --json-errors had already solved precisely this
at gsd-tools.cjs:4455, under a comment naming the hazard verbatim: "The argv
splice must happen here too, otherwise the dispatcher below sees
--json-errors as an unknown command." The later flag never got the same
treatment.

Fixed rather than documented around: the version is resolved first — which
memoizes the cell and makes an invalid value throw early — and then every
--exit-contract= token is spliced out of the dispatcher's argv copy.
--exit-contract is now listed in TOP_LEVEL_USAGE, where it never was. The
regression test pins leading position, trailing position, agreement between
the two, and a loud failure on v3 rather than a silent fall back to v1.

Neither review engine would have caught this: the defect is invisible in the
diff, because the diff does not touch argv handling. It surfaced only from
running the documentation's own example. Writing a how-to is an execution pass.

Verification runs on the remote runner.

* fix(#3912): the flag splice has to run before the run-with-timeout return

An isolated review of the previous commit found that the fix did not deliver
what it claimed, and that two of its own tests were weak. All three findings
reproduced by execution before any change was made.

The fix was placed below a return. main() intercepts `run-with-timeout` at
gsd-tools.cjs:4436 and returns from there — above both the --json-errors block
and the --exit-contract splice added in the previous commit. So the flag still
died in leading position for that one command:

    $ gsd-tools --exit-contract=v2 run-with-timeout 5 -- node -e "..."
    Error: Unknown command: run-with-timeout        (exit 64, child never ran)

The previous commit message and the test's describe-block both claimed
position-independence unconditionally. That was an overclaim, not a gap left
open, and it is the part worth naming: the fix was verified by hand on the
commands I happened to think of, and `run-with-timeout` returns before the
code I was verifying.

Both global-flag blocks now run above the interception, with a comment naming
it so a later edit cannot slide them back down. Moving --json-errors up fixes
the identical pre-existing bug for that flag, verified failing beforehand
(exit 1, sdk_unknown_command). Fixing the sibling is deliberate: same defect,
same block, and a known-broken twin next to a fixed one is not a resting state.

Two tests were not pulling their weight. The invalid-value test was vacuous —
it passed against the pre-fix build, because `--exit-contract=v3` already
exited 1 there and already printed the resolve error lazily through
error() -> getContractVersion. Both its assertions held before the fix, so it
pinned nothing. The real discriminator is that the pre-fix build emits BOTH
"Unknown command: --exit-contract=v3" and the resolve error, while the fixed
build emits only the latter; the test now asserts that absence.

The leading-position and leading==trailing tests asserted proxies — "not 64",
"no Unknown command", "the two agree" — none of which pin a value, and all of
which would survive both positions being identically broken. With a .planning
directory and no STATE.md, state-snapshot exits exactly 80 under v2 and 0
under v1 in both positions. Those numbers are pinned now. The multi-token case
the descending splice loop exists for is covered too, and run-with-timeout has
regression tests for both flags.

The lesson is narrower than "test more". Hand-verifying the production
behavior does not verify that the test would have caught its absence. The
pre-fix binary has to be run against the test's own assertions.

Investigated and deliberately not changed: splicing before --cwd parsing
degrades one diagnostic from "Missing value for --cwd" to "Invalid --cwd:
<path>", but that is pre-existing — verified on the pre-fix build via
--json-errors, which already did it. This change joins the pattern rather than
creating it, and both forms exit 64 on malformed input either way.

Verification runs on the remote runner.

Refs #3912

* chore(#3912): backfill changeset pr numbers to 3983

* test(#3912): pin the reason-table invariant as set equality, not a count

A graph-backed review flagged the unchecked lookup in
expectedErrorCode3912. Investigated by execution: the drift guard DOES
hold — for an unmapped reason under v2 the production error() yields 1
while the table yields undefined, so the assertion fails. Not a
correctness defect, and deliberately NOT made tolerant, since a tolerant
lookup would destroy the guard.

Two real problems remained. The guard asserted the wrong invariant: it
counted the TABLE's keys at 25 rather than checking they match the
ENUM's values, so a renamed member keeps the count at 25 and slips past,
and a 26th member leaves the table at 25 and slips past too. Both were
then caught only indirectly, by an undefined mismatch producing 'must
exit undefined'. It is now a sorted set equality, so the failure names
the specific missing or extra reason.

And the comment above it described a '?? FAIL' fallback that does not
exist anywhere in the function. It now states what the code actually
does, verified by running it rather than by reading it.

d98b55562c enhance(#3910): the raw terminator is banned by construction (#3980)
* enhance(#3910): move the last src/ terminators onto the seam

Phase 6 bans the raw terminator by construction, which it cannot do while
violations stand. A census found 12 sites the rule would flag; nine of the ten
unsanctioned ones were owned by no phase of the epic at all — a coverage hole
in the decomposition, since P0-P2 are infra, P3 the gate modules, P4 the
scanners, P5 the fragments, P7 the hooks, P8 io.cts, and P6 itself only adds
the rule. `src/**/*.cts` now holds exactly 2 raw exits, both inside
`terminateNow`, the single sanctioned site.

`io.cts`'s `error()` is the interesting one. It was first called substantive on
"dozens of callers, contract risk" — asserted, not measured, and the
measurement refuted it: 289 call sites, zero inside a try whose catch would
swallow a throw. The real obstacle was structural instead: `terminateNow`
cannot emit exit 1, because ADR-3889 §1 makes 0 and 1 unallocatable and
`nameForExitCode(1)` throws. So the only route is `ExitError` under `runMain`,
which sets exitCode and writes stderr only when the error carries a user
message — keeping the existing stderr write and throwing a message-less
ExitError is observably identical.

That census was still too narrow, and running the CLI proved it. It asked
whether the CALL sits in a try/catch; the two regressions that surfaced were
interceptors elsewhere on the stack:

- `command-routing-hub.cts`'s `dispatch()` swallowed the ExitError into a
  HandlerFailure, so the caller emitted a duplicated, wrong stderr line on
  every Hub-routed path. It now rethrows ExitError explicitly — the same shape
  `gsd-tools.cjs` already used at two dispatch sites, so this follows an
  established idiom rather than inventing one.
- the profile-pipeline router's deliberately un-awaited `.catch(e => error(...))`
  turned an ExitError rejection into an uncaught exception; it now mirrors
  runMain's handling.

`edge-probe` and `ui-consideration-probe` gained `runMain` wrappers because
probe-core's new throwing default would otherwise have escaped them.

A follow-up sweep of every dispatcher — 19 command routers, the Hub, the
gsd-tools dispatch seams — found no further swallowing catch. The admitted
bound: ~1260 non-rethrowing catches repo-wide were scanned structurally but not
individually classified. Both real regressions were found by execution, not by
reading, so the suite is the detector that matters here.

`gsd-tools.cjs:253` stays a raw exit deliberately: it is the ensureRuntimeBuild
bootstrap, which runs before cli-exit is required, so the seam does not yet
exist. It needs a second allowlist entry, which means #3910's "single allowlist
entry" criterion is unachievable as written.

Verification runs on the remote runner.

Refs #3910

* enhance(#3910): ban the raw terminator by construction

Adds local/require-registered-exit and registers it on all four globs:
src/**/*.cts, scripts/**/*.cjs, hooks/**/*.js, gsd-core/bin/**/*.cjs.

Registering on the .cts glob is load-bearing, not redundant — the emitted .cjs
mirrors are globally eslint-ignored, so a rule registered only on the emitted
globs is blind to the sources. That is the #3496 lesson, and it is how the
previous guard became invisible: n/no-process-exit was 'error' in one block yet
fired zero times on all three surfaces that mattered.

The dead n/no-process-exit: 'off' block for hooks is deleted in the same PR.
Phase 7 migrated every hook, so the exemption now protects nothing.

Two allowlist entries, not the one #3910 anticipated. terminateNow's body is
detected STRUCTURALLY — a process.exit lexically inside a function of that name
— rather than by a path and line number that rots. The second is
gsd-tools.cjs's ensureRuntimeBuild bootstrap, an inline disable with its reason
at the call site: it runs before ./lib/cli-exit.cjs is required, so the seam
does not exist yet and no migration is possible. #3910's 'single allowlist
entry' criterion is therefore unachievable as written, and is amended with the
measurement rather than quietly missed.

The rule is proven able to FAIL, per glob: four positive controls, one for each
registered glob. A guard that cannot be shown to fire is not a guard. Four
matching negative controls pin process.exitCode as never-flagged — conflating
it with process.exit is what inflated this epic's original census 2x. An
allowlist case and a near-miss (same shape, different function name) fix the
structural detection in place.

Verification runs on the remote runner.

Refs #3910

* fix(#3910): stop the detached catch from throwing, and scope the allowlist

Review findings, one of them a regression the previous fix introduced.

_handlePipelineRejection called error() from inside a DETACHED .catch().
error() now throws, so that throw became an unhandled promise rejection — and
on Node >=15 with --unhandled-rejections=throw, Node dumps a raw stack trace
with absolute paths on top of the clean Error: line. That was impossible before
this branch, because process.exit(1) terminated synchronously before any
rejection machinery could observe it. The handler now writes byte-identical
stderr itself, in both plain and --json-errors form, and sets exitCode in
place. This was the THIRD interceptor found, and like the first two it surfaced
by running the CLI rather than by reading code.

The rule's terminateNow allowlist had no path constraint, so any function
anywhere named terminateNow across all four globs inherited it. It now requires
the structural nesting check AND a cli-exit.cts basename — still no line
numbers to rot.

The four per-glob positive controls only varied a filename inside RuleTester,
which never resolves eslint.config.mjs. Since the rule is filename-agnostic,
all four exercised identical logic and none proved the rule was WIRED — this
epic's own failure mode. A registration test now asserts the rule resolves for
a real path in each glob, and it is proven able to fail: removing one glob's
registration flips the resolved value from [2] to undefined.

Three evasions the rule cannot catch (computed member, aliasing, .call/.apply)
are documented in its header and pinned by tests, labelled as known limits
rather than endorsed, so a future change that starts catching them is a
deliberate diff.

Refs #3910

* docs(#3910): document the raw-terminator ban

Reference and Explanation via a new docs/features fragment (FEATURES.md is
generated from it, not hand-edited). How-To:
docs/how-to/resolve-a-raw-terminator-finding.md, indexed from docs/README.md —
a contributor whose code trips the rule picks among three replacements by
surface (runMain/ExitError for a CLI path, terminateNow for a hook,
process.exitCode where the process should drain), and needs to know why
process.exitCode is correct and never flagged, since conflating the two is what
inflated this epic's original census 2x.

The page also names the three patterns the rule cannot catch and says plainly
that using one to dodge it is a review finding, not a fix — documenting them
without that sentence would read as a sanctioned workaround.

docs/INVENTORY.md deliberately untouched: eslint-rules/ is not a tracked family
in the manifest (verified — a regen produced a zero diff), so a hand-written row
would desync the table from the family it claims to belong to.

Refs #3910

* fix(#3910): a catch that sniffs the message swallows an ExitError

The remote run returned 41 failures, and one of them was a live production
regression rather than a test artifact.

`cmdMilestoneComplete`'s unstarted-phase guard re-threw only when
`e.message.startsWith('Cannot mark milestone complete:')`. `error()` used to
`process.exit(1)`, uncatchable, so the guard always fired. It now throws an
ExitError carrying no message, the string test fails, and the ExitError was
silently swallowed — the guard stopped blocking milestone completion entirely.
Proven against the real CLI: pre-fix, a milestone with an unstarted phase
archived at exit 0; post-fix it is blocked at exit 1 with the intended message.

That is a guard that silently stopped guarding, which is this epic's thesis
appearing inside the phase meant to enforce it. Worth stating plainly: an
earlier census DID examine this site, saw a `throw e`, and classified it as
rethrowing. It was wrong — the rethrow is conditional, and a conditional
rethrow on an inspected message is indistinguishable from an unconditional one
unless you read the predicate.

So the class was swept rather than patched where it was tripped over. An AST
census of every CatchClause across src/, gsd-core/bin/ and scripts/ found 38
conditional rethrows. Two more had the same defect and are fixed the same way:
`config.cts`'s `'No config.json'` sniff and `gsd-tools.cjs`'s
`e.name === 'WindowsError'`. The remaining 25 are provably unreachable — every
one wraps a bare fs, YAML, manifest-require or git-exec primitive that cannot
throw ExitError — and two were scanner false positives, both explained. Each
fix is an unconditional `instanceof ExitError` rethrow placed BEFORE any
inspection, matching the idiom command-routing-hub and gsd-tools already used.

Residual bound, stated rather than implied: zero known-reachable unfixed sites,
contingent only on error() never later being called inside one of those 25
primitive try blocks.

The remaining failures were harness artifacts, and the harnesses were corrected
to the new contract rather than the assertions weakened. Tests that mocked
`process.exit` to observe termination now catch ExitError and assert its code;
tests parsing stderr as a single JSON object still assert exactly that, with
their ad-hoc `node -e` scripts wrapped in runMain so it is true. milestone and
phase-resolution-parity needed no test change — they were correctly written
against the real bug and are what caught it.

Verification runs on the remote runner.

80734a9694 chore(#3053): clock-seam ADR-456 amendment + backfill — H2 (#3332)
* test(#3314): backfill deterministic clock-seam coverage (failing-first)

Replaces loose regex/range assertions with exact-value and boundary
tests for the CLI-subprocess and in-process clock-touching call sites
identified by H2's audit (epic #3053): cmdCurrentTimestamp,
_wsParseRetryAfter (commands.cts), cmdInitManager's is_active gate and
cmdInitQuick's quick_id generation (init.cts), and reapStaleTempFiles
(io.cts). The CLI-subprocess-pinned tests are expected RED until a
follow-up commit routes those call sites through realClock so
GSD_TEST_MODE+GSD_NOW_MS can reach them.

* refactor(#3314): route CLI-subprocess clock reads through realClock

cmdCurrentTimestamp, cmdInitManager's is_active gate, and cmdInitQuick's
quick_id generation read Date directly, which the GSD_TEST_MODE+GSD_NOW_MS
subprocess pin cannot reach (it only fires inside realClock.now()).
Behavior-preserving: realClock.now() falls through to Date.now() whenever
GSD_TEST_MODE is unset, which is every real invocation.

* docs(#3314): amend ADR-456 with reachability-based clock-control rule

ADR-456 §(a) documented one mechanism (injected {clock=Date} +
t.mock.timers). Adds the two this repo already relies on: t.mock.timers
for in-process direct-Date reads, and the GSD_TEST_MODE+GSD_NOW_MS
subprocess pin (routed through realClock) for CLI-spawned code. Updates
TESTING-STANDARDS.md's matching passages, which already referenced this
issue by number as the no-elapsed-assertion promotion precondition.

* fix(#3314): address orthogonal review findings

Spec-axis findings: file and link the no-elapsed-assertion promotion
follow-up (#3331) instead of leaving TESTING-STANDARDS.md pointing at
a dead #1885, and ship the module-by-module audit table in the ADR
itself rather than only in a gitignored phase artifact.

Standards-axis finding: pin the "hour-old file = not active" test via
GSD_TEST_MODE+GSD_NOW_MS for consistency with the reachability rule
this PR's own ADR amendment now documents.

9faacc0c15 test(#3148): bound the long tail and delete the unbounded-spawn allowlist (#3192)
* test(#3148): bound the long tail and delete the allowlist

Migrates the final 170 unbounded sync spawn sites across 49 files, then
removes the allowlist entirely. local/no-unbounded-spawn now runs with no
exemption surface across tests/**: there is no file to add a name to.

drift-detection's throw-native git() helper routes to gitOrThrow -- bare
runGit would have taken 16 call sites quiet on failure. commands.test.cjs
has two independently-scoped runGsdTools/runCli helpers, one already bounded
and one not; they are kept distinct rather than unified, the same trap as the
two same-named git() helpers in Wave 1.

runNpm's bound was erasable. Its options spread callerOptions after the
defaults, so an explicit timeout:undefined silently dropped the 180000ms
bound -- the rule flagged it and was right; it was not a false positive. Fixed
by destructuring with a default, with a test that fails when the default is
removed.

Two sites stay on a raw spawn with an explicit timeout because the seam
cannot express them: one needs shell:true for npm.cmd on Windows, one
redirects stdout to a real fd. Both are the rule's own documented second
option, not an escape from it.

Closure verified rather than asserted: the derivation scan reports 0 unbounded
spawn helpers and 0 unbounded direct git call sites, and a temporary file
carrying an unbounded spawn still errors with the allowlist gone.

Closes #3064.

* test(#3148): close a hole in the guard's own eslint-disable ban

The ban listed only the top level of tests/, so it was blind to 37 .cjs
files under tests/helpers, qa, observability, fixtures and dispatch. With the
allowlist deleted this test is the sole remaining way to detect someone
silencing the rule inline, so the gap was load-bearing: a nested file could
carry an unbounded spawn plus an eslint-disable and pass everything.

Proven before and after. A probe planted under tests/helpers with both was
invisible to the guard and clean under eslint; after making the listing
recursive the guard fails on it. The scanned set goes from 771 files to 808.

Pre-existing since the guard shipped, but this wave is what promoted it to
sole defense, so it is fixed here rather than filed.

Also converts the last hand-rolled throw check to throwIfFailed and the last
re-derived legacy shape to compose toLegacyResult, which makes the epic's
none-remain claim true rather than nearly true. toLegacyResult itself is not
widened -- eight callers depend on its shape and one consumer does not
justify changing a shared contract.

* fix(#3148): correct seam incoherence at the bound and a slow review-lane error path

Two real failures from the remote runner, both fixed at the cause.

The seam could return outcome TIMED_OUT together with exitCode 0. At the
exact bound spawnSync reports ETIMEDOUT while the child has already exited
with a real status, and toSeamResult classified on the error code while
passing status straight through -- an incoherent pair its own boundary test
was written to catch, and did. A status that is not null is direct evidence
the child exited on its own, so it now decides the outcome before the
error-code branches run. process-seam.cjs was deliberately untouched by every
earlier wave; this is a defect in the module itself, kept surgical, with a
unit test that fails against the old logic.

review-lane with an unknown subcommand fell through to its usage error only
after loading the capability registry and building a per-lane plan, which
spawns one child process per lane -- up to twelve. The error path took
~1288ms instead of ~119ms, and under bench load it outran a caller's spawn
timeout and was killed before writing anything, which is the empty stdout and
stderr CI saw. It now fails fast before any of that work begins.

This is the epic's first production change. It is user-facing, so it carries
a changeset rather than a no-changelog label.

* test(#3148): replace a real-race timeout test with a deterministic one

E9 raced git rev-parse against a 1ms bound and assumed git always lost. On a
warm container git finishes first, spawnSync returns status 0 with no error
at all, the seam correctly classifies EXITED, and gitOrThrow correctly does
not throw -- so the test failed on both lanes. A probe confirms a genuine
timeout always carries status null, so this was never the seam misbehaving.

Raising the bound would only lengthen the odds, which is the same defect with
better luck. The test now drives gitOrThrow against a stubbed runGit that
returns a synthetic TIMED_OUT result, so it asserts exactly what it always
meant to -- that a timeout propagates as a throw -- with no timing
dependence. Five consecutive runs are identical where the old one varied.

I wrote this test in Wave 0; it is a real-race test by construction and
CLAUDE.md says to replace those rather than re-run them.

0cc7a1a426 test(#1974): consolidate 27 installer/hooks remainder tests into module suites
Fold 27 issue-named installer/hooks/statusline/migration/reapply regression files
into their canonical module suites (installer-migrations, installer-migration-report,
gsd-statusline, reapply-verify-hunks, install-*, gsd-check-update-worker-platform-gate,
etc.). Verbatim block-scoped describe wrappers; 276 subtests conserved 1:1. No new files.

The one subdir origin (tests/installer-migrations/001-legacy-orphan-files) moved up one
level into installer-migrations.test.cjs; its single ../../ module require corrected to
../ so it resolves from tests/ root (verified). Host-env pre-check: no CLI-receiving host
sets a redirecting GSD_WORKSTREAM/GSD_PROJECT value.

Regenerates regression-name allowlist (222->205), ratchets file-count allowlist (verify
11->8, validate entry removed), makes 16 relocated allow-test-rule exemptions issue-ref-
compliant (ADR-456; prunes stale ids). Repoints 15 tests/ references across state-md.md

The convergence lint only scanned src/ + gsd-core/bin, so ~35 test files

(forwarded-behaviour coverage now lives at the leaves; resolveWorktreeRoot

(the lint is removed in T-final). Dropped the stale core.test.cjs entries from

28ac89d810 fix(#1008): tolerate EAGAIN + short writes in io output()/error() (#1009)
* fix(#1008): tolerate EAGAIN + short writes in io output()/error()

The I/O Module wrote stdout/stderr with a bare fs.writeSync(fd, data), assuming
it blocks until the kernel accepts every byte. That is false when the fd is a
non-blocking pipe (as under the parallel node:test runner on Linux CI): a full
pipe throws EAGAIN and a partially-drained pipe returns a short count. The former
caused spurious failures (e.g. bug-974 graphify property test threw EAGAIN); the
latter risked silently truncating output.

Add writeAllSync(fd, data): loop on short counts and retry EAGAIN/EINTR with a
bounded backoff. The backoff sleep buffer is allocated lazily on the first retry
(rare) and reused — keeping it out of module load avoids perturbing the
SharedArrayBuffer-allocation accounting in perf-316 and costs nothing on the
common no-retry path. Route output() and error() through it; non-transient
errors (EPIPE) still propagate. Mirrors the transient-errno handling already
applied to STATE.md lock acquisition (ACQUIRE_LOCK_RETRY_ERRNOS / #3776).

Regression cases live in tests/io.test.cjs (the owning module's file, per the
regression-test-name placement policy) and inject fs.writeSync via mock.method:
EAGAIN/EINTR retry, short-write no-truncation, EPIPE still surfaces, and error()
retries while still exit(1). Red against the pre-fix bare-writeSync io.cjs.

a5d82bf98a refactor(#859): extract CLI I/O primitives from core.cts into io.cts (#864)
ADR-857 rollout phase 1. Move the CLI I/O primitives — output(), error(),
ERROR_REASON, setJsonErrorMode/getJsonErrorMode, and the output() large-payload
temp-file spillover helpers (GSD_TEMP_DIR, ensureGsdTempDir, reapStaleTempFiles)
— out of the 2271-line core.cts god-module into a new, small src/io.cts. core.cts
re-exports them so existing consumers are unaffected (behavior-preserving).

Repoint src/profile-pipeline.cts to import output/error/reapStaleTempFiles from
io directly; graphify/intel/audit were verified not to import these symbols. Net:
the leaf feature modules no longer depend on core just for I/O — the enabling
first cut toward Capability extraction.

New-CLI-module checklist: .gitignore (bin/lib/io.cjs), eslint.config.mjs ignores,
INVENTORY.md count 90→91 + io.cjs row, INVENTORY-MANIFEST.json, ARCHITECTURE.md
core.cjs/io.cjs rows, CONTEXT.md "I/O Module" glossary entry. Adds tests/io.test.cjs
(28 behavioral tests incl. shim-identity and the @file: spillover branch).

Gates: lint, code-review, security-review, codex adversarial-review, and
gsd-test-both (14742 pass on Mac + Linux Docker, 0 fail) all green.
