On this page

Every action in every component (sign-ins, refusals, proposals, orders, fills, rule changes, reviews, loads, workflow actions, demo role switches) goes into one append-only log.

The event log
Each row: when, who, category, action with details, what it was on, the outcome and the hash.

Reading it

Filter by category (auth, access, entitlement, portfolio, market, order, execution, compliance, surveillance, ai, pipeline, admin, report, blotter, operations, data, feeds, workflow…) and outcome (ok, denied, failed). Each row: number, when, who, category, action with its details (e.g. rule.signoff {"as":"compliance",…}), the record it was on, the outcome, and the hash.

The hash chain

Each row stores the SHA-256 of the row before it, so changing or removing a row breaks the chain. Verify the chain recomputes it and says whether every hash matches, or the first row that does not.

What it is for

Who did what and when; every refusal (with what was missing); the evidence behind sign-offs, overrides and loads. Over the API, GET /events pages through it and GET /events/verify verifies it.

  • The AI interaction log Every AI call: purpose, model, latency, tokens, user or API client, and the full input and output, encrypted at rest.
  • The rule register Every rule with its original wording, what is enforced, its versions, sign-offs with their test bench, and its violations; a PDF for auditors.
  • Users and permissions Invite users, set each one's role, account permissions and privileges, disable users and reset authenticators.
  • Load history Every batch: who loaded it and when, the file's SHA-256, the counts and its status; open one for the diff, the rejected rows, undo and the original file.

Do it with the API

Every action on this screen can also be done by your own systems, under the same permissions. See Authentication to get a token.
