lakehouse/auditor 1 blocking issue: todo!() macro call in tests/real-world/scrum_master_pipeline.ts
The compose-don't-add discipline applied to the original ask: when big
models produce good results (scrum reviews + observer escalations),
save them into the matrix indexer so future small-model handlers can
retrieve them as scaffolding. Local model gets near-paid quality from
a fraction of the cost.
New: scripts/build_answers_corpus.ts indexes lakehouse_answers_v1
from data/_kb/scrum_reviews.jsonl + data/_kb/observer_escalations.jsonl.
doc_id prefixes ('review:' vs 'escalation:') let consumers same-file-
gate the prior-reviews case while keeping escalations broad.
observer.ts: buildKbPreamble adds lakehouse_answers_v1 as a third
retrieval source alongside pathway/bug_fingerprints + lakehouse_arch_v1.
qwen3.5:latest synthesis now compresses three lenses into a single
briefing for the cloud reviewer.
scrum_master_pipeline.ts: epilogue dispatches a fire-and-forget rebuild
of lakehouse_answers_v1 after each run so this run's accepted reviews
are retrievable within ~30s. LH_SCRUM_SKIP_ANSWERS_REBUILD=1 disables.
Verified live: kb_preamble grew 416 → 727 chars after wiring third
source; qwen3.5:latest synthesis (702 → 128 tokens) compresses
correctly; deepseek-v3.1-terminus diagnosis (301 → 148 tokens) is
sharper, citing architectural patterns (circuit breaker, adapter
files) instead of generic timeouts. Total cost per escalation
unchanged at ~$0.0002.
