Background and Context

The Output Rendering Framework has three remaining integration gaps tracked in Epic #936:

  1. Spec envelope mismatch: The code uses {command, session_id, elements, exit_code, timing, metadata} but the spec defines {command, status, exit_code, data, timing, messages}. This misalignment (tracked with #884) must be resolved.

  2. No streaming materialization: The --stream flag for commands that produce progressive output (e.g., plan execution) requires a streaming materialization mode that progressively renders output in real-time. This is not yet implemented.

  3. Missing output format tests: BDD (Behave) and Robot Framework integration tests for each output format are needed to verify the full pipeline.

Parent Epic: #936 (Epic: Output Rendering Pipeline Integration — Wire Commands to OutputSession Framework)

Acceptance Criteria

  • Output envelope is aligned to spec: {command, status, exit_code, data, timing, messages} (coordinates with #884)
  • session_id field is replaced by status, elements by data, metadata by messages
  • Streaming materialization mode is implemented for --stream commands
  • Streaming mode progressively renders output elements as they are produced
  • BDD (Behave) scenarios cover each output format (rich, json, yaml, plain, color)
  • Robot Framework integration tests verify command output structure matches spec envelope
  • All nox stages pass with coverage >= 97%

Subtasks

  • Update OutputSession envelope fields to match spec: status, data, messages
  • Update all materializers to use the new envelope field names
  • Implement StreamingMaterializer that progressively renders elements as they arrive
  • Wire --stream flag in CLI commands to use StreamingMaterializer
  • Write Behave feature file output_formats.feature with scenarios for each format
  • Write Robot Framework test suite output_structure.robot for command output structure
  • Verify coverage >= 97% via nox -s coverage_report
  • Run nox (all default sessions), fix any errors

Definition of Done

  • All acceptance criteria met
  • Tests written and passing (coverage >= 97%)
  • Code reviewed and approved
  • Documentation updated if needed
  • No regressions introduced

## Background and Context The Output Rendering Framework has three remaining integration gaps tracked in Epic #936: 1. **Spec envelope mismatch**: The code uses `{command, session_id, elements, exit_code, timing, metadata}` but the spec defines `{command, status, exit_code, data, timing, messages}`. This misalignment (tracked with #884) must be resolved. 2. **No streaming materialization**: The `--stream` flag for commands that produce progressive output (e.g., plan execution) requires a streaming materialization mode that progressively renders output in real-time. This is not yet implemented. 3. **Missing output format tests**: BDD (Behave) and Robot Framework integration tests for each output format are needed to verify the full pipeline.
