Rpi

RPI

Run one experiment from the caller's existing intent source through three responsibilities and stop:

Plan -> Implement -> fresh Validate -> report

RPI preserves the original intent and dispatches each core phase at most once. It does not own retries, budgets, queues, claims, leases, Git, delivery, release, closure, or the caller's next decision.

The pure scripts/run_once.py reference behavior makes the dispatch and stop semantics executable without Git, ao, or a tracker.

Contract

1. Resolve the existing bead or caller intent. Invoke Plan once only if that source needs shaping; Plan updates the same source or proposes an amendment. It creates no AgentOps packet. The runtime snapshots the exact resolved source bytes under their digest, including when the conversation is the only source, before dispatching Implement or a fresh Validate context. If usable intent cannot be established, report NOT_PLANNED and stop.
2. Invoke Implement once with the resolved intent. It performs one bounded experiment; the runtime derives subject identity and check receipts. If no subject is built, report NOT_BUILT and stop.
3. Invoke Validate once in a context distinct from the author's context. Pass the intent reference and digest, exact subject manifest, factual receipts, validator identity, and freshness attestation.
4. Return the durable verdict.v2 reference and a short report. Stop regardless of PASS, FAIL, or NOT_PROVEN.

NOT_PLANNED and NOT_BUILT are report statuses, never semantic verdicts. A caller may revise the bead or caller intent and start a new invocation. RPI never creates a parallel revision artifact or selects the next work itself.

Proportionality guard

RPI does not turn each component, gate failure, or specialist comment into a new planning artifact. A terminal caller goal may remain one bounded experiment across several source owners when they serve one outcome and one acceptance boundary.

If control artifacts or fresh-validation cycles are multiplying faster than implementation evidence, stop dispatching more lanes. Return to one outcome-level intent and continue with targeted deterministic checks, reserving the full integration check and fresh verdict for the frozen subject. This changes orchestration cost, never acceptance, exact identity, fail-closed scope, or verdict authority.

Continuation envelope

Before dispatching any lane, the orchestration declares its envelope: a budget (maximum lanes per wave, maximum repair revisions per wave) and a checkpoint rule — the second non-PASS outcome on one intent stops that lane and returns to the caller instead of dispatching another attempt. An orchestration without a declared envelope does not converge; it accretes lanes. The 2026-07-15 heal-skill fold ran three intent revisions (.agents/ao/intents/sha256/26a4f2be...eb48 lineage) and a NOT_PROVEN then PASS verdict pair (.agents/ao/verdicts/sha256/b6e759dd...cb6a, e9b6cdb8...37b9) before an enforced two-stop checkpoint ended the wave.

Delegate with minimal context: a lane receives the frozen intent reference and the established facts it needs, never the orchestrator's full conversation history. If a lane cannot proceed from the intent alone, the plan failed the fresh-context test and should be repaired at the source, not padded with chat transcript.

Lanes whose write scopes share a regen surface (the same generated outputs, mirrors, or manifests) serialize; only lanes with disjoint source scopes and disjoint regen surfaces may run in parallel.

Invariants

• Acceptance and its runtime-derived digest do not change between phases.
• The runtime derives complete changed-path coverage or Validate returns NOT_PROVEN.
• A proven change outside write_scope makes the verdict FAIL.
• PASS requires nonempty distinct author and validator context IDs plus an explicit freshness attestation.
• Optional Premortem, Postmortem, Council, genie, factory, tracker, and runtime adapters are caller-selected. They do not alter phase order or core outcomes.
• Learn is an optional later consumer of verdict collections and is not part of this invocation.

Report

RPI has two report surfaces. Keep them distinct:

1. Machine artifact: return or persist the exact rpi-report.v1 object for adapters, automation, and audit.
2. Interactive response: summarize that object for the caller in natural language. This is the default assistant response.

Lead the interactive response with the status and one sentence stating the caller-visible outcome. Follow with only the strongest proof, any material unchecked scope, and a clickable verdict reference when one exists. Name why no subject exists for NOT_PLANNED or NOT_BUILT. Keep the response to one short paragraph or at most four bullets.

The machine artifact remains behind the verdict/report link. Emit its full JSON or YAML object only when the caller explicitly requests machine-readable output or an adapter consumes the response. Raw digests, schema fields, and exhaustive check lists stay in the artifact unless an integrity failure makes one necessary to explain the result.

Do not append a next action. The caller owns continuation.
