- bubble-race-repro.ts: shared driver harness for repro tests
- bubble-race-repro-defect-{1,2,3,4}.test.ts: real-browser RED tests
that fail without the fix and pass with it
- Defect 1: fast-replay false-positive settle on count
- Defect 2: multi-turn flicker via list[last]
- Defect 3: cascade-tier blindness
- Defect 4: boot-time baseline staleness / pre-paint placeholder
- bubble-race-mechanisms.test.ts: GREEN tests pinning internal
contracts (cascade-pollution guard, atomic readCascadeState,
init-script idempotency)
- wait-for-turn-complete.test.ts: 3-conjunct classification matrix
- probe-contract.test.ts: ctx-bridge shape
- sse-counter.test.ts: counter increment + framenavigated reset +
handle-cache invalidation
