- engine: wo_idx_probe answers single-column equality from the index hash buckets (idx_hash_key1 reproduces idx_hash bit for bit; verify compares exactly as the slab walk did, so results identical); composite indexes keep the walk; both executors wired (local + DB actor RPC) - compiler: probe_key_of_where lowers "var.col == key" on an indexed column to DB_PROBE; all where guards still run (guard stays the final arbiter); keys = ident/int-literal only; Float/Bytes excluded (engine raw-eq narrower than VM float-eq) - measured: reads 1.3k -> 1.3M ops/s, p50 600us -> 1us (~x850); query x830; mixread 1.3k -> 89k s1, 21 -> ~1.9k sN - gate policy moved into the driver (tolerance_for: refresh-proof); latency floors max(4x,100us); quick mode skips poll-bound mix floors; both tolerance classes proven to bite - proof: test_table wo_idx_probe suite (RED first), corpus query-index-probe 105/0, full battery green, TSan clean, two campaigns pass the refreshed baseline Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
