ROOT CAUSE (found via instrumentation, not hunch): After a 20-scenario corpus batch, only 6/40 successful (role, city) combos ever triggered playbook_memory citations on subsequent runs. Added `playbook_boost:` tracing::info! line in vectord::service to log boost map size vs candidate pool vs match count. One query revealed: boosts=170 sources=50 parsed=50 matched=0 170 endorsed workers came back from compute_boost_for — but zero were in the 50-candidate Toledo pool. The boost map was pulling globally- ranked semantic neighbors (top-100 playbooks across ALL cities), dominated by Kansas City / Chicago / Detroit forklift playbooks the Toledo SQL filter would never admit. The mechanism was correct at the per-playbook level; the problem was pool intersection. FIX (surgical, not cap-tuning): - playbook_memory::compute_boost_for_filtered(): accepts optional (city, state) filter. When set, skips playbooks from other geos BEFORE cosine-ranking, so top-k is within the target city. - Backwards-compatible: compute_boost_for() calls the filtered variant with None — existing callers unchanged. - service::hybrid_search(): extracts target (city, state) from the executor's SQL filter via a small parser (extract_target_geo), passes to compute_boost_for_filtered. VERIFIED: Before fix: boosts=170 sources=50 parsed=50 matched=0 (0% hit) After fix: boosts=36 sources=50 parsed=50 matched=11 (22% hit) Top-k=10 now has 7/10 boosted workers with 2-3 citations each. Boost values 0.075-0.113 on cosine scores 0.67-0.74 — meaningful reorder without saturation. scripts/kb_measure.py: Aggregator that reads data/_kb/*.jsonl and playbooks/*/results.json, reports fill rate, citation density, recommender confidence trend, and zero-citation-ok combos (item 3 target signal). Used to measure before/after on bigger batches. Diagnostic logging stays — the class of "boosts computed but not matched" bug can recur if the SQL filter format ever drifts, and without the counter it's invisible. Every hybrid_search with use_playbook_memory=true now logs its boost stats.
