Two gap-fills surfaced by the real test on 2026-04-20: 1. /log no longer seeds endorsed_names that don't exist in workers_500k for the contract's (city, state). Previously accepted ghost names silently (entry count grew, SQL row landed, but boost never fired because no real worker chunk matched the stored tuple). Response now reports rejected_ghost_names and explains why seeding was skipped. 2. Bun /search auto-appends `CAST(availability AS DOUBLE) > 0.5` to sql_filter when the caller didn't constrain availability themselves. Recruiters expect "available workers" by default — surfacing someone on an active placement would break trust on first contact. Opt out with `include_unavailable: true`. Verified: ghost names rejected end-to-end, real names accepted, mixed input handled correctly. Availability filter drops ~10 workers from a 305-row Cleveland OH Welder pool to 295 actually-available.
