# Blueprint Parallel Implementation Result

- Date: 2026-06-04
- Branch: `codex/blueprint-parallel-implementation`
- Plan: `docs/plans/2026-06-04-blueprint-to-parallel-implementation.md`

## Completed

1. Blueprint-ready execution routing
   - Clear implementation intents such as `개발해라`, `구현해라`, `진행해라`,
     `이대로 만들어라`, and `/execute` use the existing ready blueprint.
   - Ambiguous blueprint-ready text no longer discards the existing blueprint.
     In TTY it falls through to the action picker; in non-TTY it continues
     blueprint refinement.
   - `WorkflowInputAction.execution_requested` records execution-only workflow
     routing without starting a new deliberation.

2. Blueprint freeze artifact
   - Execution approval writes the approved blueprint to
     `.trinity/workflow/blueprints/<workflow_id>.json`.
   - The execution-enabled event records the frozen blueprint path and generated
     work package ids.

3. Deliverable-first work package decomposition
   - `BlueprintDecomposer` now creates packages from blueprint deliverables:
     architecture components, data flow, external dependencies, and risks.
   - Active providers are assigned by current load balance first, provider fit
     second, and `codex -> claude -> antigravity -> gemini` only as a tie-breaker.
   - `WorkPackage.estimated_weight` is persisted and used for balancing and
     execution group preview.
   - Component dependencies resolve to package ids when blueprint component
     dependency names match generated package keys.

4. Execution planning visibility
   - `WorkflowEngine.plan_parallel_groups()` previews dependency-ready,
     file-ownership-safe groups.
   - `/workflow` displays planned parallel group count and a blueprint-ready
     next-action hint.
   - `/packages` displays dependencies, expected files, and estimated weight.

5. Execution prompt boundary
   - Package prompts include estimated weight and a workspace boundary section.
   - Providers are instructed not to branch, merge, commit, or push; integration
     remains orchestrator-owned.
