Adds a periodic-tier E2E that catches the May 2026 transcript bug shape
the existing single-finding gate-tier floor test cannot detect: a model
that fires one AskUserQuestion and then batches the remaining findings
into a single "## Decisions to confirm" plan write + ExitPlanMode.
Why a separate test from skill-e2e-plan-eng-finding-floor: the gate-tier
floor (runPlanSkillFloorCheck) exits on the first AUQ render and returns
success, so a once-then-batch model would pass it trivially. This test
uses runPlanSkillCounting at periodic tier with N-AUQ tracking and
asserts >= 3 distinct review-phase AUQs on a 4-finding seeded plan.
- test/fixtures/forcing-finding-seeds.ts: FORCING_BATCHING_ENG fixture
(4 distinct non-trivial findings spread across Architecture, Code
Quality, Tests, Performance — mirrors the D1-D4 transcript shape)
- test/skill-e2e-plan-eng-multi-finding-batching.test.ts: new test
- test/helpers/touchfiles.ts: registered in BOTH E2E_TOUCHFILES and
E2E_TIERS (touchfiles.test.ts asserts exact equality)
Test will fail on baseline today because today's model uses the preamble
fallback to batch findings; passes after the architectural fix lands in
a follow-up commit.
