/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).
