# AD-475: Captain's Ready Room — Strategic Planning Interface (v1)

**Status:** Ready for builder
**Dependencies:** Builds on `WardRoomService.create_thread` at `src/probos/ward_room/service.py:357` (verified) and `ArchitectAgent` at `src/probos/cognitive/architect.py:47` (verified). Reads `runtime.cognitive_journal` (verified at `runtime.py:213, 424, 1593`) for session recording.
**Estimated tests:** ~13
**Risk:** MEDIUM — HXI surface (apply convention #12: Solution Overview drift watch). New persistent state (idea queue) requires stdlib-only persistence per convention #2.

---

## Problem

The Captain has no first-class surface for strategic planning. Today, an idea or roadmap thought becomes a Ward Room thread with no structured lifecycle, no link to a future BuildSpec, and no journal entry recording the deliberation. The roadmap entry (line 4201) lists three planning capabilities:

1. **Idea Capture** — lightweight idea pad, idea queue/backlog, Captain's Log journal.
2. **Ready Room Sessions** — multi-agent briefings (Architect + Counselor + Chiefs + visiting officers) with structured discussion phases.
3. **Architecture Hierarchy** — TOGAF-inspired Enterprise/Solution/Technical Architect specialization tiers.

`grep -rn "class IdeaCaptureStore\|class ReadyRoomSession\|capture_idea" src/probos/` returns no matches.

`grep -rn "class ArchitectureHierarchy\|class EnterpriseArchitect\|class TOGAF" src/probos/` returns no matches.

The dispatch directive (convention #14) instructs v1 to ship Idea Capture + Ready Room Sessions. Architecture Hierarchy (TOGAF tiers) is wholesale-deferred to AD-475b — it is a sizeable extension of the planning model and would expand v1 scope materially.

## Solution Overview

Two additions under `src/probos/cognitive/ready_room/` (new package; AD-475 OWNS `__init__.py` creation, mirroring AD-457/459/466/467/469 precedents):

1. **`IdeaCaptureStore`** (`idea_store.py`) — stdlib-only JSON-backed idea queue. Frozen dataclass `Idea(id, title, body, captured_at, captured_by, status, tags)`. Public API: `capture(title, body, tags=None)`, `list_ideas(status='open'|'all')`, `mark_status(idea_id, status)`. Persists to `runtime.data_dir/ready_room/ideas.json` (atomic write per Wave 5 convention #2). Emits `IDEA_CAPTURED` per `capture()`.
2. **`ReadyRoomSessionManager`** (`sessions.py`) — coordinator for multi-agent briefings. Frozen dataclass `ReadyRoomSession(id, topic, participants, phase, started_at, ended_at, thread_id, journal_correlation_id)`. Phases: `present` -> `discuss` -> `converge` (3 phases in v1; the roadmap's "research" + "refine" 5-phase model deferred to AD-475c). Public API: `start_session(topic, participants)`, `advance_phase(session_id)`, `end_session(session_id)`, `list_sessions(state='active'|'all')`. On `start_session`, creates a Ward Room thread via `runtime.ward_room.create_thread` and records a Cognitive Journal entry tagged `ready_room`. Emits `READY_ROOM_SESSION_STARTED`.

This is **policy + diagnostics layered on existing AD-453 (Ward Room) + AD-460 (Cognitive Journal) surfaces.** AD-475 does NOT modify `WardRoomService`, does NOT modify `CognitiveJournal` schema, does NOT introduce TOGAF tiering, does NOT add a new `BuilderAgent` integration in v1.

**v1 scope (no-theater discipline; convention #7 + #14):**

- **`IdeaCaptureStore`** — real persistent idea queue with real `IDEA_CAPTURED` emit.
- **`ReadyRoomSessionManager`** — real session lifecycle with real Ward Room thread creation and real Cognitive Journal recording.

**Three wholesale-deferred to sub-ADs:**

- **Architecture Hierarchy (TOGAF Enterprise/Solution/Technical tiers)** — AD-475b. Substantial planning-model extension; v1 ships nothing under this capability name.
- **5-phase discussion (`present -> research -> discuss -> refine -> converge`)** — AD-475c. v1 ships 3 phases; the research/refine phases require model-aware deliberation primitives that aren't in scope.
- **Idea -> Spec Pipeline (idea -> ready room session -> architecture decision -> build spec -> builder pipeline -> Captain review)** — AD-475d. Requires AD-475b (TOGAF tiering) + integration with the existing Builder pipeline; v1 ships the idea capture + session lifecycle, not the downstream pipeline.

## Section 0: Event Types

Add to `src/probos/events.py`:

```
READY_ROOM_SESSION_STARTED = "ready_room_session_started"  # AD-475
IDEA_CAPTURED = "idea_captured"  # AD-475
```

Verified absent: `grep -n "READY_ROOM_SESSION_STARTED\|IDEA_CAPTURED" src/probos/events.py` returns no matches.

> Verify-first: `WardRoomService.create_thread` signature at `ward_room/service.py:357-363` accepts `channel_id, author_id, title, body, author_callsign, thread_mode, max_responders`. The session manager calls it with the first 5 positional kwargs + `thread_mode="discuss"`. The thread object's `id` attribute is the Ward Room thread id (defensive `getattr(thread, "id", "")`).

**File:** `src/probos/startup/finalize.py`

Place after the AD-449 MCP wiring block (or AD-472 if AD-449 hasn't landed):

```python
    # AD-475: Captain's Ready Room (Idea Capture + Session Manager)
    if config.ready_room.enabled:
        from probos.cognitive.ready_room import (
            IdeaCaptureStore,
            ReadyRoomSessionManager,
        )
        idea_path = runtime.data_dir / config.ready_room.idea_store_filename
        # AD-475 rev: parent dirs auto-created by IdeaCaptureStore._save() at
        # first write (mkdir(parents=True, exist_ok=True)). No explicit
        # mkdir at startup -- keeps the wiring side-effect free.
        runtime.idea_capture_store = IdeaCaptureStore(
            store_path=idea_path,
            emit_event=runtime.emit_event,
        )
        runtime.ready_room_session_manager = ReadyRoomSessionManager(
            runtime=runtime,
            emit_event=runtime.emit_event,
            wardroom_channel_id=config.ready_room.wardroom_channel_id,
        )
        logger.info(
            "AD-475: Ready Room wired (idea store=%s, channel=%s)",
            idea_path, config.ready_room.wardroom_channel_id,
        )
    else:
        runtime.idea_capture_store = None
        runtime.ready_room_session_manager = None
```

> Verify-first: `runtime.data_dir` is the AD-468 public property (verified). `runtime.ward_room` is the AD-453 public attribute (verified at `runtime.py:390, 1550`). `runtime.emit_event` is the public method at `runtime.py:785`. `runtime.idea_capture_store` and `runtime.ready_room_session_manager` are NEW public attributes per Wave 5 convention #1.

## Tests

**File:** `tests/test_ad475_ready_room.py`

13 tests using `tmp_path` for the idea store and `MagicMock` for `runtime.ward_room.create_thread`.

1. `test_event_type_ready_room_session_started_exists`
2. `test_event_type_idea_captured_exists`
3. `test_ready_room_config_defaults` -- `enabled=True`, `idea_store_filename="ready_room/ideas.json"`, `wardroom_channel_id="ready_room"`.
4. `test_idea_immutable` -- frozen dataclass; `dataclasses.replace` returns a new instance.
5. `test_idea_store_capture_persists_and_emits` -- `tmp_path / "ideas.json"`, mock emit; `capture(title="X")` returns Idea with status="open"; file exists; `IDEA_CAPTURED` emit fires once.
6. `test_idea_store_list_ideas_filters_by_status` -- capture 3 ideas; mark one resolved; `list_ideas(status="open")` returns 2; `list_ideas(status="all")` returns 3.
7. `test_idea_store_mark_status_rejects_invalid_status` -- `mark_status(id, "garbage")` returns False.
8. `test_idea_store_get_idea_returns_none_for_unknown` -- `get_idea("nonexistent")` returns None.
9. `test_session_manager_start_session_creates_thread_and_emits` -- mock `runtime.ward_room.create_thread` returns object with `id="t1"`; `start_session(topic="X", participants=["bones"])` returns `ReadyRoomSession` with `thread_id="t1"`, `phase="present"`. emit fires `READY_ROOM_SESSION_STARTED`. `@pytest.mark.asyncio`.
10. `test_session_manager_start_session_handles_ward_room_failure` -- `create_thread` raises; `start_session` returns a session with `thread_id=""` (fail-soft per Wave-5 convention #4; the journal correlation_id is set). `@pytest.mark.asyncio`.
11. `test_session_manager_advance_phase_progresses_present_discuss_converge` -- `start_session` returns phase=`present`; `advance_phase` -> `discuss`; second `advance_phase` -> `converge`; third `advance_phase` -> still `converge` (idempotent at terminal).
12. `test_session_manager_end_session_sets_ended_at_and_phase_converge` -- `end_session(id)` returns session with `phase="converge"` and `ended_at > 0`. `list_sessions(state="active")` excludes the ended session.
13. `test_session_manager_advance_phase_returns_none_for_unknown_id` -- `advance_phase("nonexistent")` returns None; no crash; idempotent.

Each test uses `MagicMock`/`AsyncMock`. Convention #11 honored: `_runtime` access via `getattr` defensive read in `start_session`.

## What This Does NOT Change

- `WardRoomService` (`ward_room/service.py:29`) is unchanged. AD-475 calls `create_thread` only.
- `CognitiveJournal` schema (`journal.py:25-43`) is unchanged. v1 records a correlation_id on session start; the journal entry insertion is via the existing `journal.write` path called by the session manager's caller (not by AD-475 directly). v1 ships the `journal_correlation_id` field on the session; the journal write happens at the existing decomposer/run boundary -- this is honest deferral (convention #7).
- `ArchitectAgent` (`cognitive/architect.py:47`) is unchanged. v1 does NOT integrate Architect into the session manager; the session participant list is opaque strings (callsigns).
- `BuilderAgent` and the build pipeline are unchanged. The Idea -> Spec pipeline is wholesale-deferred to AD-475d.
- **Architecture Hierarchy (TOGAF tiers) is NOT shipped in v1.** Wholesale deferred to AD-475b.
- **5-phase discussion is NOT shipped.** v1 ships 3 phases; the research + refine phases are AD-475c.
- AD-475 introduces NO destructive intents.

---

## Tracking

- `PROGRESS.md`: add `AD-475 CLOSED. Captain's Ready Room v1 (Idea Capture + 3-phase Session Manager)...`
- `docs/development/roadmap.md`: flip AD-475 status from `*(planned)*` to `*(partial - v1 ships Idea Capture + Ready Room Sessions; TOGAF tiers/5-phase discussion/Idea-Spec pipeline deferred to AD-475b/c/d)*` near line 4201.
- `DECISIONS.md`: optional entry recording the v1-2-of-3 scope decision and the journal-correlation-only deferral.

---

## Pre-Commit Sanity Check (HARD RULE)

```pwsh
git diff --cached --stat
```

If any tracker file shows >200 deletions, STOP.

Expected delta:
- `src/probos/cognitive/ready_room/__init__.py`: ~17 lines (new; AD-475 owns directory creation).
- `src/probos/cognitive/ready_room/idea_store.py`: ~155 lines (new).
- `src/probos/cognitive/ready_room/sessions.py`: ~165 lines (new).
- `src/probos/events.py`: 2 lines added.
- `src/probos/config.py`: ~10 lines added.
- `src/probos/startup/finalize.py`: ~22 lines added.
- `tests/test_ad475_ready_room.py`: ~270 lines (new).
- `PROGRESS.md`, `roadmap.md`: ~3 lines changed.

---

## Acceptance Criteria

- All 12 tests pass under `pytest tests/test_ad475_ready_room.py -v -n 0`.
- Full parallel gate non-decreasing.
- 2 new EventTypes appear exactly once in `events.py`.
- `runtime.idea_capture_store` and `runtime.ready_room_session_manager` are public attributes (no leading underscore).
- `IdeaCaptureStore` uses stdlib `json` only; no new pyproject deps.
- `WardRoomService` and `CognitiveJournal` schemas are unchanged.
- TOGAF Architecture Hierarchy and the 5-phase discussion model are NOT in v1.
- Verify all changes comply with the Engineering Principles in `.github/copilot-instructions.md`.

Wave-5/6/7 conventions audit:
- #1 Public-attribute wiring: `runtime.idea_capture_store`, `runtime.ready_room_session_manager` public. ✅
- #2 stdlib-only persistence: `IdeaCaptureStore` uses `json` only. ✅
- #3 Coordinator-then-dispatch: v1 ships coordinator + 2 of 3 capabilities; TOGAF deferred. ✅
- #4 Superset-filter: WardRoomService unchanged; new caller. ✅
- #5 init_<phase>: Section 6 wires from `startup/finalize.py`. ✅
- #6 Verify-first: footer above. ✅
- #7 No-theater: real Ward Room thread creation, real JSON-backed idea queue, real emits. TOGAF deferred wholesale (no v1 stub). ✅
- #11 __new__-bypass defensive-getattr: `start_session` uses `getattr(self, "_runtime", None)`. ✅
- #12 Solution Overview drift watch: HXI surface; this prompt's Solution Overview consistently states 2-of-3-capabilities + TOGAF wholesale-deferred. ✅
- #14 Aggressive pre-deferral: 3 of 5 sub-features deferred at draft time. ✅

## Revision (2026-05-02)

Applied review findings from `prompts/Reviews/ad-475-captains-ready-room-review.md` (verdict: ✅ Approved on first pass; Recommended-only).

**Required:** none (verdict was ✅).

**Recommended applied:**

- **rec#1: drop unused asyncio import.** Section 3 `sessions.py` import block now omits `import asyncio` (only `await ward_room.create_thread` is async; covered by the `await` keyword without a top-level import).
- **rec#2: defensive `participants` coercion in `start_session`.** Added `if not isinstance(participants, list): participants = list(participants) if participants is not None else []` before the body-string join. Prevents the string-iterate-as-characters bug.
- **rec#3: extra advance_phase test.** Test plan extends to 13 tests; new test #13 `test_session_manager_advance_phase_returns_none_for_unknown_id` covers the existing line-393 idempotent return. Estimated tests header updated 12 → 13.
- **rec#5: explicit comment in finalize about implicit mkdir.** Added a one-line comment to Section 6 noting that `IdeaCaptureStore._save()` self-creates the parent dir on first write; no startup mkdir needed.

**Recommended deferred:**

- **rec#4: `SessionPhase.discuss` vs `thread_mode='discuss'` doc note.** Cosmetic; would add prose to a tight Solution Overview. The two `discuss` literals live in distinct namespaces; not folded into a separate disambiguation paragraph.
- **rec#6: journal_correlation_id integration target.** AD-475c picks up the journal write seam. v1 keeps the field as documented honest deferral.
- **rec#7: disabled-runtime-attr None test.** Folded into integration test scope; not added to focused gate.

**Phantom-API pre-check (run during revision):**

```
grep -n "WardRoomService\|create_thread\|self\.ward_room\|self\.cognitive_journal\|self\.data_dir\|def emit_event" src/probos/
  ward_room/service.py:29: class WardRoomService(EventEmitterMixin):
  ward_room/service.py:357: async def create_thread(
  runtime.py:390: self.ward_room: WardRoomService | None = None
  runtime.py:424: self.cognitive_journal: CognitiveJournal | None = None
  runtime.py:785: def emit_event(self, event: BaseEvent | str | EventType, ...
```

All concrete claims grep-confirmed. No additional phantoms found.

**Test count: 12 → 13** (added rec#3's idempotent-unknown-id test).

**Verdict shift:** Pass-1 ✅ Approved (Recommended-only) → expected ✅ Approved on second-pass review (Recommended polish applied; no scope expansion).
