Methodology fix: gen_real_queries.go gains -offset N flag. Every prior
real_NNN test sourced queries from rows 0-9 of fill_events.parquet
(default -limit 10), so the substrate's published "8/10 cold-pass top-1
= judge-best" was measured on a memorized slice, not held-out data.
real_006 samples 50 fresh rows (offset 10, never seen by the workers
or ethereal_workers corpora). Same harness, same local qwen2.5:latest
judge, same K=10. ~14 min wall total. Local-only, no cloud calls.
Headline findings:
- Cold-pass top-1 = judge-best (rank match): 41/50 (82%) vs real_001's
8/10 (80%) — substrate generalizes at rank level.
- Strict (rating ≥ 2): 34/50 (68%) — 12-point drop from real_001's
80%. ~7 of 41 "no-discovery" queries had cold top-1 the judge rated
1; the corpus has gaps for some role-city combos in the v3 slice.
- Verbatim lift: 9/9 discoveries → warm top-1 (clean, matches real_001 2/2)
- Paraphrase recovery: 6/9 → top-1, 9/9 any-rank
- Quality regressed: 3/50 — Q43 is the structural one
Q43 (Packer at Midway Distribution / Chicago IL) regressed from
rating 5 to rating 2 on warm pass with `warm_boosted_count=0` and
`playbook_recorded=false`. Q18 (Shipping Clerks at the same client+city)
recorded a playbook entry. The regression suggests Q18's recording
leaked into Q43 via the warm-pass playbook corpus retrieval surface
even though the role gate from real_002 should have blocked it.
Three possible paths: extractor failed on one query, gate fires on
boost path but not Shape B inject, or cosine drift puts the recorded
worker close enough to Q43's embedding that warm-pass retrieval picks
it up directly. Diagnosis is the next move.
Three same-(client, city) clusters tested:
- Heritage Foods Gary IN × 3 distinct roles: clean, distinct workers
- Riverfront Steel Columbus OH × 4: cosine-level confusion (Q9/Q25
surface same worker w-281 for Assemblers vs Quality Techs at cold-
pass), but no playbook bleed
- Midway Distribution Chicago IL × 3: Q43 regression as above
What this confirms: substrate works on the fresh distribution at the
rank level, verbatim lift is real, paraphrase recovery is real.
What this falsifies: real_002's role-gate fix is not structurally
airtight. The bleed pattern can still fire under conditions the
prior tests didn't reach.
