Pre-PL1 closure (handoff 2026-09-10):
1. research_required: new nonterminal task status (records enum, state
machine edges created/running -> research_required -> running/
completed/failed/cancelled/superseded). The operator's RESEARCHED_CHANGE
disposition now transitions to research_required instead of failed —
research routing is not failure. Live canary: status=research_required,
outcome_ref=research_dispatch, route_ref set.
2. Experience consumer skips research-dispatch tasks — no false
failure-learning evidence in PL0 (verified: 0 FAILURE records for
research tasks).
3. recall_uplift A/B documented honestly in the module: latency 521-1213ms
→ 14-18ms; terms bounded (893-1665 → 16-21); recall ROW COUNTS identical
per query but 1/8-7/7 of recalled IDs differ (expansion terms differ →
different lexical candidates). Marked PROVISIONAL — quality not proven
equivalent; harness original retained for rollback.
4. Hook hardening: durable fire-trace (/tmp/rune-bridge-fire.log, one line
per actual injection with token count) + harness-internal-step guard
(checkpoint-writer/compaction steps no longer receive capsules).
5. QX7 canary fully purged: entries, contentless-FTS ghosts, both stores;
retrieval-level verification shows zero hits.
1227 tests pass; ratchet 353/80; henxels clean.
