# Requirements: v1.67 Cross-Runtime Deep Execution Parity

## Milestone Goal

Move Claude Code and OpenCode from install/front-door parity targets to honest
deep-execution parity probes against the Codex baseline, while keeping
OpenClaw explicitly deferred as a specialized lane.

## Completed Requirements

### Parity Contract

- [x] `REQ-PARITY-01`: the repository distinguishes install/front-door
  readiness from deep-execution readiness through one explicit runtime parity
  contract instead of treating a green `doctor` row as sufficient proof.
- [x] `REQ-PARITY-02`: Codex remains the declared baseline runtime with one
  bounded real-topic execution lane and artifact-quality bar that parity
  targets must be compared against.

### Runtime Probes

- [x] `REQ-PARITY-03`: Claude Code has one bounded real-topic deep-execution
  probe that enters through its supported bootstrap surface, reaches durable
  AITP artifacts, and records where it matches or falls short of the Codex
  baseline.
- [x] `REQ-PARITY-04`: OpenCode has one bounded real-topic deep-execution
  probe that enters through its supported bootstrap surface, reaches durable
  AITP artifacts, and records where it matches or falls short of the Codex
  baseline.

### Verification And Closure

- [x] `REQ-VERIFY-01`: the milestone closes with targeted regression coverage,
  one shared parity audit/report surface, and bounded acceptance evidence for
  Codex, Claude Code, and OpenCode.

## Requirement Outcomes

- `REQ-PARITY-01`: validated exactly as written through the new doctor/runtime
  truth split.
- `REQ-PARITY-02`: validated exactly as written through the Codex bounded
  baseline harness.
- `REQ-PARITY-03`: validated with an honest bounded probe; remaining live-app
  first-turn proof is deferred and explicitly reported.
- `REQ-PARITY-04`: validated with an honest bounded probe; remaining live-app
  first-turn proof is deferred and explicitly reported.
- `REQ-VERIFY-01`: validated through the shared closure audit with named open
  gaps rather than hidden debt.
