Summary

Wave D diagnosis after merging PR #100 into dev only (24be5ab). The publishable LME-20 pin is still 0/20 integrity, not quality. This PR records an item-level failure ledger, a decision gate, and the honest LoCoMo/Mem0 remasure.

A 100% SOTA guarantee is not possible. The real bar remains: beat a fresh Mem0 run on the same pinned harness while OpMem/marketing stay green. Today Mem0 leads that pin.

Changes

  • docs/benchmarks/artifacts/lme20-product-recall-pr1-20260812-failure-ledger.md — LME-20 item labels (sanitized).
  • docs/research/program-execution-status.md — histogram, gate, PR6–PR8 deferral, PR10 measurement.
  • docs/benchmarks/artifacts/locomo-pr2-dev-1x30-20260813.md — local PR2 remasure 6/30.
  • docs/benchmarks/artifacts/failure-ledger/locomo-pr2-dev-1x30.jsonl24/24 READER_MISS, oracles supported.
  • docs/benchmarks/artifacts/locomo-mem0-samepin-pr10-20260813.md — fresh Mem0 12/30 (MH 7/10).

Headline from the publishable LME json (gitignored):

  • Mean search hits 24.45 (range 6–30); empty retrieval 0/20.
  • Primary labels: EVIDENCE_COVERAGE_MISS 12, READER_MISS 6, ABSTENTION_MISS 2.
  • Pattern: assistant continuation / listicles drown user facts.

Decision gate: PR5 first (#102), then PR3 (#103), PR4 (#104), PR9 (#105). PR6–PR8 deferred — 1×30 WRONG items are reader misses with coverage supported, not missing edges.

Same-pin (this day)

System Overall MH Temporal
Mem0 Platform 12/30 7/10 2/16
Brainy local PR2 24be5ab 6/30 4/10 1/16

Local 6/30 is a dip vs staging post-cutover 15/30. Do not blend with Gate 0 18/30. LME-20 quality remains 0/20; LME-100 is not a quality run.

Test plan

  • Markdown + jsonl only; no runtime change in this PR.
  • Confirm no secrets/base URLs in the ledger/pins.
  • LoCoMo 1×30 remasure pinned (6/30).
  • Fresh Mem0 same-pin pinned (12/30).

Linear / tracking

Competitive program after #100. Wave 1 code: #102#105.

Mine the publishable 0/20 pin into an item-level histogram. 0/20 is not
empty ingest (mean 24.45 hits). Gate: PR5 first, then PR3/PR4/PR9;
defer PR6-PR8. No quality claim.

Honest Wave D remasure: local PR2 6/30 (24/24 READER_MISS, oracles
supported). Fresh Mem0 12/30 (MH 7/10) on the same dataset SHA.
Mem0 leads; no SOTA. PR6-PR8 stay deferred.
