Discover executors, tools, safety boundaries, and default fixture.

Return implemented features, safety exclusions, and runtime readiness.

Validate and expand the deterministic ORCL fixture without running it.

Run all stages deterministically and store the in-memory result and events.

Return the canonical plan for the active host harness; accepts no model credentials.

Validate completed host stage outputs and atomically publish the final dossier.

Create a durable credential-free host run with decision-memory recall.

Start a prepared durable host run and return its first stage.

Append safe live stage/tool receipts without prompts, raw arguments, or credentials.

Commit and checkpoint one completed host stage, then return the next stage.

Pause a host run at its next portable stage boundary.

Resume from the first incomplete portable stage; replay interrupted work.

Return durable lifecycle status, revision, checkpoint, cancellation, and next stage.

Read live lifecycle events after a monotonic cursor.

Request cooperative cancellation; the host owns interruption.

Acknowledge host interruption and make cancellation terminal.

Validate all committed stages and atomically publish the completed dossier.

Export a bundle with atomic first publication and crash-recoverable validated overwrite.

Recall up to five same-symbol and three cross-symbol prior decisions.

Append a host-observed outcome and reflection to a prior research decision.

Validate portable observable invariants; optionally verify pinned checkout identity.
