Personal agents

Seams ① Record to ⑤ View. Build: the five layers for an agent acting for one person. Conform to: draft-mih-agent-evidence-request-00 (the History profile).

The same five layers, applied to an agent that acts for one person: the host's seams, the records they produce, the person's own book, the deals those records belong to, and a History the person chooses to share, which shows counts and makes no outcome claim.

4Example

The positive case of the published conformance vectors: a holder stream of four deals, three selected for one recipient. Below are the definition the recipient holds, the artifact of one reply (deal 50c8…, decoded from the reply's base64url artifact), and the deal states the test derives. All keys are test keys.

The reply that carries this artifact is in the vectors, driven by their producer/main.go; any conforming book must produce the same reply. The twelve cases are this positive run, ten mutant cases covering the nine mutants of the profile's §6.4 (each fails the property §6.4 names), and one refusal to another requester.

5Status

Tags: live running in a personal-agent host (none today) · built-not-live merged or released at a SHA, not running in any personal-agent host · designed written down, no code · planned named as an open point, not designed.

Not to be confused: history_card/1 is a different derivation, registered by the evidence-request Internet-Draft (a checkpoint history with no record content). The personal History on this page is personal_history_basic/1, a separate, recipient-specific derivation.

6Specs

• Internet-Draft draft-mih-agent-evidence-request-00 — the request, the correlation subject, derivation by definition digest, derivation-scoped disclosure.
• Internet-Draft draft-mih-agent-evidence-layer-00 — the record header (record_type, epistemic_type) a History reads.
• Internet-Draft draft-mih-scitt-agent-action-capsule-05 — the record format capsule-emit seals for tool calls and approvals.
• Internet-Draft draft-mih-scitt-checkpointed-local-log-02 — the checkpointed log under the person's book.
• RFC RFC 8785 — JSON Canonicalization Scheme: the bytes the derivation digest covers.
• Profile spec/personal-agent-history-profile-v0.md — Personal-Agent History Profile v0 (informational, pre-Internet-Draft).
• Profile spec/interop-profile-v0.md — the interop profile (evidence-interop/0) whose envelope and verifier a History uses unchanged.
• Code action-state-group/capsule-emit python/v0.11.0 — the MCP adapter and approval records.

7What you need before the next step

• Your host's four seams named: connector calls, approvals, scheduled tasks, and a hook that carries each to the sealer.
• One correlation id per deal, chosen at random when the deal opens, and a mapping from your native step status to step_completed / step_failed.
• One holder key answering every deal of a History, and a pre-release scan for text outside the four declared fields.
• A verifier display that shows “outcomes not established” before any count, and never combines the counts.
• Next, a second party: work an agent does for someone, with a counterparty who keeps its own records.
