# AD-475 Build Report

**Date:** 2026-05-02
**Builder:** Wave 8 continuous-build (1 of 6)

## Sections Implemented

| Section | File | Status |
|---|---|---|
| Section 0+4: EventTypes | `src/probos/events.py` | ✅ Added `READY_ROOM_SESSION_STARTED`, `IDEA_CAPTURED` after AD-463 anchor (line 211) |
| Section 1: Package init | `src/probos/cognitive/ready_room/__init__.py` (new) | ✅ Owns directory creation |
| Section 2: IdeaCaptureStore + Idea | `src/probos/cognitive/ready_room/idea_store.py` (new) | ✅ Frozen Idea + JSON-backed store with atomic write |
| Section 3: ReadyRoomSessionManager + ReadyRoomSession + SessionPhase | `src/probos/cognitive/ready_room/sessions.py` (new) | ✅ 3-phase enum + frozen session dataclass; `import asyncio` dropped per rec#1 |
| Section 5: ReadyRoomConfig | `src/probos/config.py` | ✅ Added Pydantic class after `ModelRoutingConfig` (line 1105) + field on `SystemConfig` after `model_routing` (post-line-1693) |
| Section 6: finalize.py wiring | `src/probos/startup/finalize.py` | ✅ Wires `runtime.idea_capture_store` + `runtime.ready_room_session_manager` after AD-463 ModelRouter block (line 614+) |
| Tests | `tests/test_ad475_ready_room.py` (new) | ✅ 13/13 pass at `-n 0` |
| Tracking | `PROGRESS.md`, `docs/development/roadmap.md:4201` | ✅ Updated |

## Test Results

- Focused gate: `pytest tests/test_ad475_ready_room.py -v -n 0` → **13/13 passed in 0.26s**
- Full parallel gate: **10,476 passed (+12 vs baseline 10,464), 14 skipped, 1 environmental error**
- Environmental error: `tests/test_memory_architecture.py::TestOracleService::test_oracle_query_episodic_only` — passed at `-n 0`. Classified as parallel-xdist flake per BUILDER-EXECUTION-PLAN decision tree step 2. Not a regression.

## Notes / Decisions

- Anchor-chain fallback applied: AD-475 is built FIRST in Wave 8, so AD-472 / AD-449 / AD-469 anchors don't exist yet. Used Wave-7-stable anchors:
  - Section 4 (events.py): anchored on `MODEL_FALLBACK = "model_fallback"  # AD-463` (line 211)
  - Section 5 (config.py): anchored on `model_routing: ModelRoutingConfig` (line 1693)
  - Section 6 (finalize.py): inserted after AD-463 `runtime.model_router = None` else branch (line 614)
- Revision-pass corrections honored: `import asyncio` dropped from sessions.py; defensive `isinstance(participants, list)` coercion in `start_session`; test #13 `test_session_manager_advance_phase_returns_none_for_unknown_id` added.
- TOGAF Architecture Hierarchy / 5-phase / Idea→Spec pipeline all wholesale-deferred at draft time per convention #14. v1 ships nothing under those capability names.
- All 15 standing conventions applied (#1 public attrs, #2 stdlib-only, #3 coordinator-then-dispatch, #6 verify-first, #7 no-theater, #11 defensive getattr, #12 Solution Overview drift watch, #14 aggressive pre-deferral).
