v1.70.1.0 fix: ship names the /document-release subagent at every decision point (tripwire + gate E2E) (#2700)

* fix(ship): name the /document-release subagent at every Step 18 decision point

The v1.54.0.0 carve moved Step 18 (documentation sync) into
ship/sections/pr-body.md and the Claude-host skeleton stopped saying
"document-release" anywhere in the workflow body — the dispatch became
invisible at exactly the moments an agent decides whether to open the
section. Restore visibility at three touchpoints, all subagent-framed
(never bare-slash-framed, which would invite an inline Skill invocation
that bypasses the fresh-context subagent + JSON contract):

- manifest trigger (renders into the section-index row AND the STOP
  pointer): "dispatching the /document-release subagent to sync docs
  (Step 18) and then creating or updating the PR/MR (Step 19)"
- Step 17 handoff line names Step 18's dispatch explicitly
- new hoisted doc-sync invariant beside the PR-title invariant: the
  dispatch itself is never skipped; only a failed subagent is
  non-blocking

Pin it in carve-guards: 'the /document-release subagent' (all three
touchpoints) + 'dispatches the /document-release subagent' (invariant)
must stay in the skeleton; the carved imperative 'Dispatch
/document-release as a subagent' must stay carved. Skeleton cap
91,600 → 92,300 (measured 91,764; trigger renders twice). Goldens
regenerated for all three hosts.

* test: pin the ship→document-release Step 18 wiring with a free tripwire

Five substring/structure asserts across the carved section, the Claude
skeleton's three touchpoints, the manifest trigger, and the codex/factory
goldens (inlined Step 18 ordered before Step 19). Claude-golden asserts
deliberately omitted: host-config.test.ts already enforces golden ==
generated byte-for-byte.

* test: gate-tier E2E proving /ship dispatches the document-release subagent

New skill-e2e-ship-docsync: a live agent gets the sliced Step 17→19 tail
of the generated ship skeleton in a bare-remote git fixture (Steps 0-16
"done"), under a fake HOME so the STOP pointer and the Step 18 subagent
prompt resolve to planted copies, with a stub document-release skill that
returns the empty-result JSON contract. Hard assert: an Agent/Task
tool-call matching /document-release/i exists in result.toolCalls and
precedes any `gh pr create`. Neutral prompt (no STOP-Read priming, no
document-release mention — the prompt echoes into the transcript, so
asserts read toolCalls only).

Hardening from review: throw-on-marker-drift fixture slice; per-test
GSTACK_HOME + .redact-prepush-prompted marker (routes Step 17's
credential guard to its silent branch — the hermetic GSTACK_HOME pin
defeats a HOME-only override); 480s/540s timeouts (nested subagent adds
wall clock the 300s sibling never carried); 'timeout' accepted in
exitReason only because the dispatch assert is independently hard;
whole-file describeE2ETier('gate') composed with diff selection (keeps
the file out of the periodic shard census, which sits at its ceiling,
and under the hard tier-alignment invariant).

Registered as 'ship-docsync' in E2E_TOUCHFILES + E2E_TIERS (gate) in the
same commit — touchfiles.test.ts rejects either half landing first.

* docs: fix stale document-release TODOS entry + three review-deferred items

The SHIPPED entry still described the deleted Step 8.5 post-PR cat-delegation
design from v0.8.4; replace with the current Step 18 subagent design and its
test pins. Add the three P3 items deferred from the v1.69 plan review:
dispatch receipt enforcement, land-and-deploy→canary dispatch-pin pattern,
and the periodic shard-census boundary.

* fix: pre-landing review fixes

Testing-specialist findings, all mechanical: (1) pin the E2E fixture's git
branch (-b main / init.defaultBranch=main) and assert every setup command's
exit status so operator git config can't silently corrupt a paid run;
(2) tighten the dispatch matcher to Step 18-prompt-specific markers
(document-release/SKILL.md | executing the /document-release workflow) so a
subagent merely quoting section text can't false-pass the regression assert
(verified against recorded burn-in transcripts); (3) replace the subsumed
carve-guards anchor with three non-overlapping per-touchpoint anchors
(gerund/imperative/3rd-person) so each touchpoint is independently enforced.

* fix: red-team review fixes

Five informational findings: TODOS shard-census arithmetic corrected (census
is 67 with one free ungated slot; the SECOND ungated file trips the floor)
and version pointer fixed (v0.18.2.0, not v0.18.1.0); the free tripwire now
pins the two dispatch-matcher marker strings so a pr-body prompt reword
fails the free suite instead of surfacing as a paid-tier mystery; the E2E
matcher gains a section-paste exclusion (scaffold strings disqualify) —
verified against all recorded runs; the E2E header documents the tierless
test:evals invisibility tradeoff.

* fix: adversarial review fixes

Pin the E2E matcher's two EXCLUSION markers in the free tripwire (an
unpinned 'Parent processing:' reword would silently deaden the
section-paste guard while every test stayed green); add an ordering pin
(the hoisted doc-sync invariant must sit above the pr-body STOP pointer —
presence-only anchors can't catch drift below it); plant a third
cwd-relative pr-body copy inside the fixture repo, gitignored so the agent
never tries to commit test scaffolding.

* chore: bump version and changelog (v1.70.1.0)

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

* docs: CHANGELOG accuracy fixes from the doc-release review

Three factual corrections the Step 18 doc subagent caught in the fresh
v1.70.1.0 entry: 5 tripwire tests (not 6), cost floor $0.63 per the cited
eval store (not $0.59), and the visibility claim scoped to decision points
(the re-run checklist mention survived the carve). Plus the E2E header's
stale pending-burn-in note replaced with the observed numbers.

* fix: raise bun-polyfill subprocess budget to 60s for degraded Windows runners

The 50ms-sleep test blew the 20s budget on BOTH bun retry attempts on PR
#2700's windows-latest runner (run 32989821401) — sustained AV/runner
pressure, not just the documented cold-start. Same flake passed-on-rerun on
the prompt-token-load-reduction branch yesterday. Budget only; every
assertion still checks exact output.

* fix(ci): run the ship-docsync gate E2E in the evals matrix + silent-skip tripwire

The evals.yml matrix is hand-enumerated and the Run step never exported
EVALS_TIER, so the new whole-file-gated ship-docsync E2E would have
self-skipped even with a row — a hollow green one layer deeper than the
documented rehomed-monolith incident. Add the e2e-ship-docsync row with a
row-level `tier: gate` property, exported as EVALS_TIER by the Run step
(empty = unset for every existing row: all readers are `=== '<tier>'` or
truthiness).

New free tripwire test/evals-workflow-matrix.test.ts ratchets the class:
matrix files must exist; gate-hosting files must have a row; whole-file-gated
matrix files must carry a matching row tier; and the burn-down lists enforce
their own cleanup. It enumerates the PRE-EXISTING holes found while wiring
this (8 gate-hosting files with no row; codex/gemini rows running zero tests;
the pty-plan-smoke row hollow since its files adopted describeE2ETier) —
tracked in TODOS as the CI gate-lane hollow-coverage burn-down.
