Hack Hydra 2026 · evidence ledger
Executed evidence, bounded claims, no hidden nulls.
The judge ledger contains executed results, retained negative/null evidence, canonical object identities and explicit N/A states where a scalar is not defined. It does not convert unexecuted work into a green badge.
Every judge-facing state has a declared evidence class.

LongMemEval full500 typed-memory ablation
500 cases; 23,867 sessions; 4,776 entities; 3,506 facts; 470 retrieval-scored and 30 abstentions. B/C/D did not establish a positive Hit@5 advantage over A at K=5.

PASS · EXECUTED
Context vs Entropy classification
18,567 raw findings; 18,555 context-classified; 12 abstentions; 99.9354% classification coverage. The historical Modal item remains USER_ATTESTED_REVOKED and provider_verified=false.

PASS · RECEIPT RETAINED
Hosted canonical FCG projection/readback
The retained hosted-migration receipt records database hydradg, collection default, 36 canonical FCOs, 24 canonical edges, root match and zero canonical FCO/edge/content-hash delta for the projected graph scope.
claim_ceiling=HOSTED_PROJECTION_AND_READBACK_SCOPE_ONLY
PASS · DETERMINISTIC
Website FCO identity contract
Website, Knowledge and release FCOs are content-addressed as fco:<object_sha256>. The deployed /api/release endpoint verifies one canonical 64-hex SHA-256 identity per FCO and rejects conflicting duplicate IDs in its bounded catalog.
claim_ceiling=OBJECT_IDENTITY_NOT_SCIENTIFIC_CORRECTNESS
PASS · DECLARED SYNTHETIC FIXTURE
Reference → poison → antidote visualization
Violet reference/normal, orange poison/mutation and blue antidote/restoration are explicit state colors. G*, ΔG*, Cloud Drift, total-variation mutation distance and restoration gain remain separately labeled calculations.
claim_ceiling=SYNTHETIC_INFORMATION_STATE_VISUALIZATION_ONLY
Hashes link exact retained artifacts.

A SHA-256 establishes byte/object identity for the retained artifact. It does not establish correctness or independent verification.
Academic source → internal Knowledge FCO → exact scorer contract.
G* design rationale
Enßlin & Weig (2010) → HydraDG G* Knowledge FCO
The paper is design-rationale lineage for an information/free-energy analogy; it does not define HydraDG's exact synthetic-fixture equation.

Cloud Drift source lineage
Lin (1991) → JSD Knowledge FCO
Cloud Drift is 100 × base-2 Jensen-Shannon divergence from the frozen reference distribution.

N/A is data when the scorer inputs do not exist.
T3_HOSTED_MIGRATION
Hosted HydraDB migration
Scalar context score: N/A
Reason: no governed state distribution is declared for this project/release timepoint. Hosted parity receipt: 36 canonical FCOs, 24 edges, zero canonical set/edge/content-hash delta.
T4_CONTEXT_VS_ENTROPY
Context vs Entropy
Scalar context score: N/A
Reason: no governed state distribution is declared for this project/release timepoint. 18,567 raw findings; 18,555 context-classified; 12 abstentions; 99.9354% coverage.
T5_FINAL_JUDGE_RELEASE
Final judge release
Scalar context score: N/A
Reason: no governed state distribution is declared for this project/release timepoint. Exact deployed Git SHA and WebsiteRelease FCO are resolved at build/runtime; no scalar G*/Cloud Drift is fabricated without a declared distribution.
