/simplify over a97efb6..HEAD (the plan_version 1.9 / trial-4 delivery).
- coordinator-contract: engine names come from engine-findings ENGINES;
one markedMajorCodeReview predicate under both lowering checks;
isEngineFinding everywhere; the unreachable branch (c) of
illegalBriefLowering folded into (e).
- armB workflow: RULE_KEYS = Object.keys(RULE_TIERS); the engine map is a
literal pinned equal to ENGINES by the workflow test.
- plan-schema: usesFilesGrammar() is the one 1.9 check (validator, sweep,
testFirstFiles, stepTestsOnlyFromFields); opensEntry built on opensChunk.
- plan-validator: one issue builder for the Files and Test first grammar.
- plan-scope-sweep: the 1.9 and the 6.2.0 reader are one if/else.
- artifact-commit: TRAILER_RE/trailerProblem no longer exported (no
importer); the order comment says the CLI finds the repo root first.
- tests: the lock drivers in session-id-isolation (d) run side by side per
mode (~100 s -> ~30 s); a shared artifact-repo helper; severityRank and
extractFindingsBlock reused; childEnv(env) without a spread; one copy of
the PLAN_VERSION_CURRENT check.
Plan readers: validator errors/warnings, plannedPaths, fieldPaths,
testFirstFiles and stepTestsOnlyFromFields compared byte for byte against
HEAD over 510 plans / 1692 steps plus 210 synthetic 1.7-1.9 cases: same.
Suite 2384 (2382/0/2).

P1 (order 2, wave 1). /trekbrief puts the task in a size class
(ceremony: small|bounded|architectural, K1; heaviest in doubt, said
aloud, overridable, only moved up) that sets the question budget and the
review cap, and asks one round of questions: facts looked up, never
asked; recommendation first; ranked by impact x uncertainty with a
visible Deferred list; stop when the next three answers can be predicted.
"høres bra ut", "gjør som du vil" and an empty answer are not approval.
K2: lib/util/approval-log.mjs, an append-only hash-chained log in the
target repo (.claude/voyage/approvals.jsonl) bound to the approved
content's sha256; append/verify (0/1/2), answer, digest. Committed by
lib/util/artifact-commit.mjs: the log always, the brief and plan only
with artifact_store: git (operator decision 2026-10-06). /trekplan
Phase 1 halts on a broken, diverged, missing or mismatched log entry;
Phase 11 logs and commits an explicit plan approval before any handoff.
Both new brief fields are optional: no brief_version bump. The
main-module guard in intent-approval.mjs and brief-validator.mjs now
compares real paths. Borrowings credited in the prose and module headers.
