Round 7 (516dffa..45aa9e1, WARN: 12 MAJOR, 0 BLOCKER) and the fence defect
found while writing its review.md. Each fix began with a test that failed on
0f400d3 (v6.3.0); suite 2208 (2206/0/2), 14 tests more.
- Tests-only (operator 2026-10-11): the plan's Files: alone decides, and the
text says so (red-proof, trekexecute Sub-step B, step-implementer,
HANDOVER-CONTRACTS). red-proof no longer reads the step's diff, so a change
already in the tree when the step began no longer counts against it, and a
plan placed outside .claude/ reads the same. The round-6 test that had the
diff overrule the plan is rewritten to the new rule.
- The Files: reader keeps a plain file beside a backticked path
(", Dockerfile", "the CLI entry src/cli.mjs", "and Makefile"). Measured on
the 520 Files: fields in 182 plans: no field reads differently.
- Red proof reports a command its timeout killed as killed after the timeout,
not "could not start"; the release check tells a timeout from output past
its buffer and from another signal. One reading of a stop
(criteria-runner stoppedBy) for red proof, the criteria runner and the
release check.
- A trailing `# comment` is dropped in a backticked check too, and in a
command passed as written, so the words screened are the words run.
- The release check reads a relative --review in --repo.
- The 15-minute timeout is defined once (criteria-runner.mjs).
- The findings check reads each cited file once per validation.
- One isMain helper (lib/util/is-main.mjs) for every CLI: the 31 copies of
the realpath guard and the 20 modules still on the file:// guard, which
exited 0 having done nothing under a symlink or a path with a space.
- The Bash guard writes its no-one-to-ask refusal once, on a direct condition.
- The findings check ends a ```json block only at a fence on its own line, so
three backticks inside a JSON string no longer end it (also in 6.2.0).
- Brief-conformance notes: a test for test-lock green on exit 127 (it
passed at once; it fails when 127 is read as could-not-run); the prose now
names the git revision `@~1` as the one leading-@ exception.
Not changed: the example plan's steps 1-2 keep their tests-only warning
(operator decision 2026-10-09; the r5 test records it). Brief note 4 (a
Regression: whose runner is not installed goes to the fix rounds) is a
routing question for the operator.

Build the prose-vs-Workflow bake-off machinery for /trekreview Phase 5-6 and
run a 1-run/arm smoke to de-risk before the full measurement (operator posture:
build + smoke, then pause for go/no-go on the full >=3-runs/arm run).
New:
- lib/review/fidelity-diff.mjs (+ tests) — the PRIMARY metric: parse two
review.md (or two structured arm outputs) and compare verdict + jaccard over
(file,line,rule_key)-IDs + per-finding severity/rule_key. Reuses jaccard +
frontmatter + NW1 findings-schema + finding-id. fidelityDiffStructured avoids
rendering review.md per run.
- scripts/trekreview-armB.workflow.mjs — Arm B: Phase 5-6 as a Workflow
(parallel([conformance, correctness]) schema-forced -> JS dedup-by-triplet ->
agent(review-coordinator) verdict schema). Path-based input via args (reviewers
carry Read). Inlines dedup + the 12-key rule_key enum (scripts have no imports).
- tests/fixtures/bakeoff/ — committable fixture: real diff of b149538 (NW1) +
brief reconstructed from plan S9. Both arms review the same pinned input.
- docs/T2-bakeoff-results.md — smoke results + verdict + go/no-go recommendation.
Smoke result: SMOKE PASS. Arm B runs the full pipeline (3 agents) with ZERO
classifier interference; fidelity EQUIVALENT to Arm A at the verdict level
(both ALLOW; jaccard 1.0). Caveat: the clean TDD'd fixture yielded ~0 findings,
so finding-SET fidelity was not stressed (only verdict fidelity proven). A
reviewer-level divergence appeared (Arm B raised 1 raw finding, coordinator
filtered it; Arm A raised 0) — to be quantified in the full run on a
richer-finding-surface fixture. NOT the T2 §5 POSITIVE/NEGATIVE verdict.
Suite 647 -> 662 (660 pass / 2 skip / 0 fail; +15 fidelity-diff). claude plugin
validate clean (known root-CLAUDE.md warning only). Plan: docs/W1-narrow-wins-plan.md S10.
