Closes #3363.

Admit the pi agent in consent/v3 and the pi host-relay capture-result submission descriptor in status/v5, with RED-first regression tests driving the real emission paths and validating full envelopes against the published schemas. Both defects were caught by the cross-lane battery conformance tier from #3362.

RDD receipt: review-e656321ae665c4bd (approved, medium, one lens, no findings).

Review Change Stack

📝 Walkthrough

Walkthrough

The PR updates the published consent and status schemas for Pi runtime output. It adds capture-result submission validation and extends conformance tests for Pi consent and host-relay status envelopes.

Changes

Pi schema conformance

Layer / File(s) Summary
Pi consent contract
contracts/review-integration/v2/schemas/consent-v3.schema.json, internal/cli/review_provider_artifact_contract_test.go, internal/cli/review_published_schema_conformance_test.go
The consent schema accepts pi. Conformance tests include the Pi runtime and configure its host-relay contract environment.
Capture-result status contract
contracts/review-integration/v2/schemas/status-v5.schema.json, internal/cli/review_provider_artifact_contract_test.go, internal/cli/review_published_schema_conformance_test.go
The status schema validates capture-result submissions, reviewer-result metadata, command arguments, and required artifact fields. Tests validate the emitted Pi host-relay STATUS envelope and update schema digests.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: 🟡 Moderate · up to d9294

The update still rejects a legacy Pi host-relay capture-result envelope that the product can emit, causing published-schema validation failures for that submission path. The PR is not merge-ready until the schema or producer behavior is corrected and covered by a full-envelope regression test.

🎯 Functional Correctness | 🟠 Major | 🏗️ Heavy lift

Support the legacy candidate-diff capture-result form.

When LegacyCandidateDiff is set, reviewCaptureInput emits review.capture-result without base_tree, candidate_tree, or --subject-hash. It still emits the capture-result submission.

Line 119 requires both trees. Line 187 requires an eight-token descriptor that includes --subject-hash. This rejects that live Pi host-relay emission.

Add a schema branch for the legacy candidate-diff form, or prevent the producer from emitting this relay form for legacy contexts. Add a full-envelope regression test for the selected behavior.

Pull request overview

Updates the published review-integration v2 JSON schemas to match envelopes already emitted by the Pi host-relay flow, and adds regression tests that validate real emitted envelopes against those published schemas (closing the conformance gaps surfaced by the cross-lane battery).

Changes:

  • Admit agent: "pi" in the published consent-v3 schema and extend the conformance test matrix to include Pi (with relay contract handshake).
  • Extend the published status-v5 schema to allow the Pi host-relay capture-result submission descriptor for the reviewer_result collect input.
  • Update schema pinning tests to the new schema digests and add a live Pi STATUS envelope conformance test.

File Description
internal/cli/review_published_schema_conformance_test.go Extends live published-schema conformance coverage to Pi consent and Pi host-relay STATUS (capture-result submission).
internal/cli/review_provider_artifact_contract_test.go Updates pinned digests for the modified published schemas.
contracts/review-integration/v2/schemas/status-v5.schema.json Admits capture-result submission descriptors in STATUS v5 and exempts review.capture-result from the no-submission rule.
contracts/review-integration/v2/schemas/consent-v3.schema.json Adds "pi" to the allowed consent agent enum.
