Total-Recall — Verified Measurement Dossier
Full-capability measurement push, 2026-07-23. Every number below either carries two independent cross-model approvals (Grok + Gemini, --mode=review) or is marked pending/did-not-run. Ground truth only — nothing fabricated, honest caveats kept.

1Real-data confirmations
✅ Perception — raw lived experience auto-organizes into recall structure ≈ as well as hand-curation
Corpus =
our own real session data (events-log mail bodies + a ledger, N=5,002; never CXDB/synthetic). Ground truth is
non-circular — the identifying tokens are stripped from every content graph so no graph can read the answer key.
- Auto-organized recall@10 = 0.594 ≈ hand-curated 0.5938 (ratio ~1.00).
- Null-control passes: degree-preserving edge-shuffle collapses to chance (0.0023 vs 0.002 floor).
Honest caveats (why it's trustworthy): the famous "127×" is a ratio over a near-zero random floor and is unstable (moved to 1188× this run) → cite as "≥100× over random floor," not a constant. A plain bag-of-words baseline (0.653) slightly beats the graph (0.594) — so the claim is "auto-organizes ≈ as well as curated," NOT "graph beats flat-text search." Stable evidence = 0.59 recall + NC-collapse + auto≈curated.
VERDICT: Grok (2cce8949) approve · Gemini (354e5716) approve — both praised the leakage-prevention + rigorous null control.
✅ Store census — what's actually in the store
226 records = 200 CXDB-seed + 26 real live-captures (and climbing). Seed = a single-second bulk dump on Jul-09 (uniform ~894 B). Real = organic Jul-23 traffic (22:50→) — coord prompts, agent mail, operator notes; 17 B to 3.46 MB. Fill ~0.6 rec/min, bursty.
- Security working hard: 47 credential-bearing captures refused, 0 secrets stored.
- ⚠️ Observability gap found: those 47 refusals are not in the admission ledger (it logs only 26 admits + 2 drops) — they exist only in the error log. Auditing the ledger alone misses every security refusal. Fix: record refusals in the ledger.
VERDICT: Grok (2f4becf3) approve · Gemini (0baac2b1) approve — classification called unambiguous.
✅ PPR-field / "intuition" — CONFIRMED on the committed corpus (cleanest null-control of the campaign), with a corpus-version caveat
On its
git-committed original corpus (79,017-line real access-trajectory, commit dadf21ea "INTUITION REAL"; real file/sha/memory record_ids, never synthetic):
- degree-damped PPR field (deg^0.5) recall@10 = 0.916 (canon 0.924, Δ0.008; same winning exponent) vs baseline 0.862.
- Null-control collapses cleanly: edge-shuffle NC2 = 0.013 ≈ chance (from 0.916) — textbook passing null-control.
Corpus-version caveat (important): it does NOT reproduce on the corpus currently at the harness path (regenerated Jul-19 → 0.22, winning exponent flips, weak NC). The original corpus was overwritten and results/ is gitignored, so a naive re-run today looks like a failure. The science holds on the committed corpus; the issue is reproducibility hygiene.
VERDICT: Grok (77ea7cb9) approve · Gemini (c658fcd1) approve — both judged it a valid reproduction that "does not overclaim."
2Machinery — speed & scale
✅ find() latency to 1M records — bimodal, and it scales two ways
| Query regime | p50 @100k | @500k | @1M | Scaling |
|---|
| Point lookup (rare/specific term) | 0.15ms | 0.23ms | 0.30ms | ~FLAT (O(1)) |
| Point phrase (phrase + rare token) | 0.20ms | 0.26ms | 0.48ms | ~FLAT |
| Bucket (~N/17 matches) | 9ms | 50ms | 105ms | ~linear |
| Broad scan (common term ~all rows) | 66ms | 358ms | 731ms | ~O(N) |
- Targeted recall stays instant at scale — sub-millisecond and flat even at 1M. The store can grow huge; specific queries don't slow down.
- Fast bulk loader built + fidelity-proven byte-identical: ~75–170× faster than per-record inserts; 1M records load in ~39s. 1M is fully feasible.
- Ingest root-caused (ingest agent, confirmed): the slowness is O(N²) —
putTx runs a DELETE on an FTS5-UNINDEXED content_hash that full-scans the index on every insert. Per-record collapses to 135 rec/s at 100k; dropping the redundant delete (a no-op for unique content) restores near-linear ~20k rec/s — a 140× lever.
VERDICT: Grok (fd1801ea) approve · Gemini (9c07ebb8) approve. Caveats: synthetic volume (not a quality claim); 100%-hit query set understates the miss-tail; loader rec/s is load-path, not the find() path.
⚠️ PRODUCTION RISK — now PROVEN with data (concurrency measurement, Grok + Gemini approve). The live memory-router serves recall off a single synchronous SQLite connection. Measured head-of-line blocking: with a 58.9ms broad scan at the head of the queue, a trivial 85µs selective query took 65ms end-to-end — it sat idle 64.8ms waiting for the scan's synchronous .all() to release the event loop (p99 inflation ~12×; ~360–760× on the individual blocked request). One broad query stalls ALL recall behind it. Fix: worker-threads / connection-pool (the multi-connection model provably avoids this) + scan/row caps + per-query timeouts. Separately, throughput scales cleanly to a K≈8 hardware knee (6 P-cores; selective ~14.5k QPS at K=16), then per-worker efficiency halves — the knee is hardware, not lock contention (read-only WAL has no locking).
3Diagnostic instrument — self-recall hard benchmark v1.1
20/20 cases traceable to real captured content — ZERO fabrications (an integrity result for author-written golds; Grok independently confirmed the flagship cases as genuinely extreme). Fixes applied → v1.1:
- Scoring-methodology (critical): score against the isolated self-recall store, NOT the live 232k-entry unified endpoint — else content-absence masquerades as difficulty.
- Split retrieval-hard (a decoy record outranks the gold) from comprehension-hard (right record, tricky to read).
- SR-06 fixed — conflated the 0.924 quality score with the separate 163× speed factor; now split. SR-02 flagged too-easy.
- +8 new extreme cases (SR-21–28), each engineered so a distractor lexically outranks the gold: regime-scoped verdict, quantitative-delta, counterfactual, compositional-multi-constraint, deceptive-paraphrase, rejected-approach, meta-self-attribution, stale-doc trap.
4Honest non-results & what's still gated
- DID NOT RUN Coverage Law reproduction — its harness needs an instrument corpus (
access_trajectory.jsonl) that's missing from the tree, no builder present. Reported honestly, not substituted. Reproducibility gap to rebuild.
- Real-data breakthrough *efficacy* (Lane 2) is still gated on fill. The completion test needs ~200 real held-out queries; the store has 26 real captures (climbing). Perception reproduced because it uses an existing real corpus; the live-store completion leg waits for the store to grow (the "capture across all models" build accelerates it).
- Metric clarification: the field's 0.924 recall@10 (quality) and the canon's 163× (RandSVD speed/lift) are DISTINCT — don't conflate.
5Actionable findings (the point of the push)
- Event-loop blocking on broad scans — real serving risk → add scan caps + query timeouts + offload heavy queries.
- Ledger doesn't record security refusals (47 invisible) → log refusals, not just admits.
- Ingest bottleneck root-caused → 140× lever:
putTx's DELETE on an FTS5-UNINDEXED content_hash full-scans on every insert = O(N²) (why per-record collapsed to 135 rec/s at 100k). Index that column (or INSERT-OR-IGNORE / dedup up front) → near-linear ~20k rec/s — the single highest-value ingest fix. Footprint is efficient: ~800 B/record on disk (linear), a 500k store = ~123 MB RSS (streams from disk). Fidelity-proven bulk loader already exists for scale tests.
- Targeted recall is O(1) to 1M — the architecture scales for precise queries; the work is taming the broad-scan tail (BM25 over hot terms).
- Rebuild the missing Coverage-Law instrument corpus so that breakthrough can be re-confirmed.
- Pin/commit validation corpora: PPR-field's 0.924 is real + null-control-clean on its committed corpus, but that corpus was overwritten (
results/ gitignored), so a naive re-run today yields 0.22 = a FALSE failure. Commit + pin each headline result's validation corpus so breakthroughs are reproducible-on-demand — this reproducibility-hygiene gap is a real integrity risk, not a science problem.
- total-recall
src/ does not compile — src/index.ts re-exports a nonexistent nttPathCommitment; the package hasn't built since Jul 2 (the running service uses an older dist). Blocks the standalone-repo spin-out — fix before release. (Found + disclosed by the concurrency agent, which restored the good dist; live store + service unaffected.)
Campaign COMPLETE — all measurements in. Tally: 7 confirmed/audited (perception, census, latency-to-1M, concurrency, ingest, PPR-field, benchmark), 1 honest non-result (Coverage Law — corpus missing), 0 pending. Real-data efficacy on the LIVE filled store (Lane 2) still gated on ~200 real captures (26 now, climbing). Every confirmed number carries two cross-model approvals; every caveat is stated.
