What's captured.

Each thing an agent or a person does on a mission becomes one ledger row. Here is what those rows hold.

  1. Prompts + retrievals

    Every prompt, every retrieved chunk, hashed.

    Kept: hashed

  2. Tool calls

    Every adapter invocation with payload digest.

    Kept: payload digest

  3. Approvals

    Approver, timestamp, hardware-token attestation.

    Kept: approver · timestamp · token

  4. Evidence packages

    Test, security, release packs signed against mission.

    Kept: signed against mission

  5. Replayable decisions

    Reconstruct any agent decision from the ledger.

    Kept: from the ledger

  6. Compliance support

    SOC 2, ISO 27001, GDPR, HIPAA evidence exports.

    Kept: SOC 2 · ISO 27001 · GDPR · HIPAA

Trust posture, in five lines.

The same five lines run along every Engyn trust page. They are collected here so you can read them in one place.

The marked line is this page's subject: the chain in the next section shows what tamper-evident means.

Edit one entry and watch the chain catch it.

This sample ledger links every row to the row before it by hash. Change an entry and each link after it stops matching, which is what tamper-evident means. Verify the chain, change an entry, then replay the decision.
