Benchmark Evidence

Last generated: 2026-06-11T22:36:41.332Z UTC
Current claim level: Local diagnostic evidence
Market leaderboard: Not open

Honest evidence for Cognibrain's engineering-memory loop. Current public status: local diagnostic evidence, no market leaderboard claim yet.

Status Current answer
Current claim level Local diagnostic evidence
What is supported Strong local evidence for coding-agent engineering-memory workflows.
What is not supported No public best-product claim, no market leaderboard, no BEAM quality claim.
Next gate Same-protocol judged runs with original competitor systems, raw outputs, hashes, and replication.

Current Verdict

Cognibrain currently has strong local diagnostic evidence for engineering-memory workflows: repeated-mistake prevention, correction carry-over, patch evidence, source-aware recall, stale-memory suppression, and guard behavior.

It does not yet publish a fair market leaderboard against original competitor systems. The current page proves a focused engineering-memory loop, not market leadership.

Evidence Matrix

Question Best current evidence Result Claim status Limitation
Can Cognibrain prevent repeated coding-agent mistakes in controlled repo-like workflows? CogniCodeBench 1,000 scenarios; 100.0% diagnostic score; 96.0% integrity L1 Local diagnostic Synthetic/internal; not market comparison
Can it retrieve relevant memory on public-style long-memory tasks? LoCoMo / LongMemEval-S / BEAM stress LoCoMo 57.9% vs Keyword Only 43.4%; LongMemEval-S 99.8% vs Keyword Only 99.0%; BEAM 51.3% vs Keyword Only 27.6% L2 Public stress diagnostic Retrieval signal only; not answer quality or competitor proof
Does it have known weaknesses? BEAM weakness analysis Abstention 0.0%; temporal and knowledge-update categories remain weak Diagnostic weakness Needs unsupported-question and temporal freshness work
Is a fair market benchmark ready? Reality Bench / EMRP gate and real-world black-box harness 9 harness slots; raw outputs and telemetry path present; market gate closed L0 Gate closed Missing same judge, original competitor command outputs, public hash, and replication
Is market leadership claimable? Reality/EMRP claim gate No L0 Gate closed Requires original competitor runs, shared judge traces, hashes, and independent replication

What The Numbers Mean

Badge Meaning Can be used publicly as
Claimable Passed quality or market gate. The exact bounded claim.
Diagnostic Useful regression or stress evidence. Internal/local evidence with the stated proof boundary.
Blocked / not scored Setup, judge, credential, or protocol gate missing. No result. It belongs in a gate or coverage table, not a score chart.

Public labels are intentionally simple:

Level Public label Meaning
L0 Not run / blocked No result. Show the reason and next gate only.
L1 Local diagnostic Regression/product diagnostic; no market claim.
L2 Public stress diagnostic Public or public-style data; no fair competitor comparison.
L3 Quality-judged evidence Same judge, raw outputs, reproducible scoring traces.
L4 Market-comparable Original systems, same protocol and budgets, public hash, independent replication.

Key Results

Benchmark evidence summary

Only scored diagnostic values appear in the chart. Closed gates and missing judge/setup states are represented below as requirements, not bars.

Result Value Evidence Boundary
CogniCodeBench full system 100.0% artifacts/cognicodebench/run.json Full local engineering-memory diagnostic
Strongest ablation: Without Temporal 87.8% artifacts/cognicodebench/run.json Internal ablation diagnostic
Keyword baseline 22.8% artifacts/cognicodebench/run.json Internal baseline diagnostic
LoCoMo diagnostic delta +14.5pp vs Keyword Only artifacts/locomo-report.json Public-style retrieval diagnostic
LongMemEval-S diagnostic delta +0.8pp vs Keyword Only artifacts/longmemeval-report.json Public-style retrieval diagnostic
BEAM 1M diagnostic delta +23.7pp vs Keyword Only artifacts/beam-1m-report.json Public-style retrieval diagnostic
BEAM abstention 0.0% artifacts/beam-1m-report.json Known weakness marker

Known Limits And Failures

  • No market leaderboard yet: no same-protocol judged original-competitor run.
  • BEAM abstention is currently 0.0% across tested splits.
  • Temporal reasoning and knowledge-update retrieval are weak.
  • Public dataset stress is retrieval evidence, not answer-quality proof.
  • Arena/API-shape rows are internal capability diagnostics, not competitor results.

Market Gate Status

Requirement Current state Note
Frozen manifest Pass Required before any market run.
Same input stream Pass Every eligible system must use the same manifest input stream.
Same judge traces Missing Missing for the current public status.
Original competitor command outputs Missing Need at least two eligible original competitor systems.
Raw outputs retained Pass Required for audit and replication.
Cost and latency recorded Pass Required for budget fairness.
Public artifact hash Missing Missing for the current public status.
Independent replication hash Missing Missing for the current public status.
Market leaderboard Closed Claim gate opens only when all evidence gates pass.

Reproduce / Artifacts

Minimal commands:

npm test
npm run build
npm run release:check
npm run benchmark:reality:run
npm run benchmark:reality:publish
npm run internal -- benchmark:summary

Generated summary artifacts:

  • artifacts/public/benchmark-summary.json
  • artifacts/docs/benchmark-summary.md
  • docs/assets/benchmark-summary.svg
  • artifacts/cognicodebench/run.json
  • artifacts/public/evidence-table/index.json

  • artifacts/longmemeval-report.json
  • artifacts/beam-report.json
  • artifacts/beam-500k-report.json
  • artifacts/beam-1m-report.json

Each visible number above is backed by a generated timestamp and artifact path. Raw outputs, scorer traces, manifest hashes, and full setup diagnostics stay in the generated artifacts until the market gate opens.

Appendix

The former artifact snapshot, maintainer refresh map, Arena API-shape rows, native competitor smoke rows, original public benchmark blockers, and full raw tables are maintainer diagnostics. They remain available in artifacts/ and generated benchmark reports, but they are not part of the public score surface while the market gate is closed.
