Not a log file. Not a database record. A cryptographic proof stack that captures what an AI knew, decided, and why β immutably, from the moment of generation.
The complete, cryptographically sealed record of what an AI system knew, what it decided, why it decided it, and how that knowledge changed over time. Not a snapshot. Not a log. A living, append-only proof chain β where every claim is classified, every context selection is recorded, every revision is sealed, and every refusal is a first-class audit event. BuildSeal implements epistemic memory across 13 infrastructure layers, all anchored to the ISCProof open protocol.
Click any layer to explore its full specification.
Ed25519 signatures, RFC 3161 timestamps, JCS canonicalization, Merkle roots. The cryptographic foundation every other layer is built on.
Every claim classified at generation: CONFIRMED, INFERRED, RECORDED_POINTER, or UNKNOWN. Epistemic scope drift is impossible.
Why a decision changed over time β sealed. Historical truth vs current truth in an append-only chain with authority and confidence scores.
Which records were retrieved, excluded, and why β captured at generation. Context selection is a first-class audit object.
Full session context sealed into a single restorable link. Provable continuity across devices and sessions. Restoration, not reconstruction.
What the AI refused β and why β is sealed. Inhibition events are first-class audit objects, not silent omissions.
JCS canonicalization β SHA-256 β Ed25519 β RFC 3161 TSA β Merkle root. Deterministic, reproducible, independently verifiable.
Reasoning posture, tone, and epistemic state sealed across sessions. The AI is provably the same agent it was in session one.
input_hash, context_hash, entity_state_hash, policy_hash β all captured at generation. Nothing reconstructed after the fact.
SCOPE_UPGRADE, EPISTEMIC_REVISION, CONTRADICTION β when the AI changes its understanding, the change is a sealed forensic record.
Coherence, trust level, threat index, signal strength β the AI's internal state at decision time is in the seal payload. Attested, not roleplay.
Returns pure database evidence packets β no model, no interpretation. The cryptographic proof speaks for itself. Regulators query directly.
Decisions relate: supports, contradicts, derived_from, supersedes, delegates_to. The full epistemic graph β sealed, queryable, verifiable.
The 13 layers run under everything. These are the surfaces you interact with.
