title: "Runtime tool fixture — fs.read"

scenario:
  id: runtime-tool-fs-read
  surface: runtime-tools
  runtimeParityTier: standard
  coverage:
    primary:
      - tools.fs.read
  objective: Verify file read behavior is tracked across OpenClaw and Codex while Codex owns read natively.
  successCriteria:
    - OpenClaw may expose OpenClaw read while Codex app-server mode may omit duplicate OpenClaw dynamic read.
    - Mock provider read plans are reported as fixture intent, not as actual runtime tool calls.
    - The row stays report-only until failure-path injection proves native Codex read behavior directly.

        action: model native read behavior separately from provider-plan capture
        reason: Codex app-server intentionally owns read natively; QA mock failure-path capture currently reports provider-plan args, not proven Codex native read behavior.

        issue: "#80312"
