+# Review Brief: FW-L3 & FW-L2 Improvements (v2)
+
+We have implemented two long-term tasks from `FUTURE_WORKS.md`: `FW-L3` (SQLite Database Normalization) and `FW-L2` (Stop Semantics Simplification), including the migration safety improvements identified in the first review round.
+
+## 1. FW-L3: SQLite Database Normalization
+- **Goal**: Transition from storing the entire JSON state as a single blob in `state` (id=1) table to a normalized table structure (`sessions` table) to support O(1) status queries, while maintaining compatibility with the existing YAML synchronization workflow.
+- **Implementation**:
+  - In `skills/lib.sh`:
+    - Updated `atomic_dump_yaml` to create and maintain:
+      - `state (id=1, data TEXT)` table (holds global metadata such as `agent_identities`, with the `tmux_sessions` key removed).
+      - `sessions (name TEXT PRIMARY KEY, status TEXT, pane_cwd TEXT, data JSON)` table (each row holds a single session entry).
+      - Added index `idx_sessions_pane_cwd` on `sessions(pane_cwd)` for faster lookups.
+    - Inside `atomic_dump_yaml`, before executing caller mutations, the complete dictionary `d` is seamlessly reconstructed from both `state` and `sessions` tables to guarantee that existing mutations still run perfectly without any modification.
+    - Updated `resolve_tmux_server`, `find_workspace_uuid`, and `is_already_stopped` to run optimized O(1) SELECT queries directly on the normalized database table when it exists.
+    - **Migration Fallback**: Added comprehensive safety fallbacks: if `sessions` table does not exist yet (OperationalError) or returns no results, the reader functions fall back to querying the old `state` table's JSON blob. This guarantees zero degradation during the migration window when readers execute before the first write.
+  - In `status.sh` and `reconcile.sh`:
+    - Adjusted the read-only DB loading logic to pull and reconstruct the `d['tmux_sessions']` list from the `sessions` table.
+
+## 2. FW-L2: Stop Semantics Simplification
+- **Goal**: Deprecate confusing `--mode soft|hard`, `--capture-id`, and `--graceful` flags. Make graceful shutdown and metadata capture the standard default behavior. Clarify the destructive `--purge-conversation` option.
+- **Implementation**:
+  - In `skills/tmux-agent-orchestrate-stop/scripts/stop_session.sh`:
+    - Deprecated `--mode`, `--capture-id`, and `--graceful` arguments. Passing these flags now raises an error informing the user that they are deprecated.
+    - Default behavior is now equivalent to the previous stop mode: it gracefully exits the agent TUI, shuts down tmux, captures conversation IDs, and updates status to `stopped` (instead of `terminated`).
+    - Added custom reasons via `--reason` (still defaults to `manual_stop`).
+    - `--purge-conversation` is retained as a destructive option to purge conversation databases and JSONLs from disk. When purged, status transitions to `terminated` and `resumable` is set to `False`.
+  - In `skills/tmux-agent-orchestrate-stop/SKILL.md`:
+    - Re-wrote the stop documentation, removed deprecated options, and aligned with the new semantics.
+  - **Stale Documentation Cleanup**:
+    - Cleaned up outdated references to `--capture-id`/`--graceful` in `resume/SKILL.md` and `monitor/SKILL.md`.
+
+## Verification Checklist for Reviewers
+1. Does the SQLite schema creation/modification in `lib.sh` preserve concurrency safety (e.g. WAL mode, BEGIN IMMEDIATE, commit/rollback)?
+2. Do the O(1) optimizations in `lib.sh` (`resolve_tmux_server`, `find_workspace_uuid`, `is_already_stopped`) fallback safely to YAML/state-blob if the SQLite DB is missing or in old schema format?
+3. Are the stop options properly simplified in `stop_session.sh`, and does the default behavior work cleanly with the database/YAML update flow?
+4. Are there any edge cases where `reconcile.sh` or `status.sh` might fail when DB is newly initialized?
+
+Please perform a code review on these changes and reply with either a detailed feedback/corrections or a `PASS`.

 ## What this skill does
 
-Stop an agent's tmux session and **mark the YAML entry (terminated or stopped)**. Preserves:
+Stop an agent's tmux session gracefully, resolve and store the conversation ID, and **mark the YAML entry (status=stopped)**. Preserves:
 
 - The tmux session's recorded `pane.pid / cmd / cwd / mcp_attachments` for audit
 - The agent's on-disk conversation (claude `*.jsonl`, agy `conversations/*.db`) — so the user can `tmux-agent-orchestrate-resume` later
 - The `start_command` so a future `tmux-agent-orchestrate-create --session <name>` reproduces the same tmux spec
 
-The user explicitly chooses:
-
-- **soft stop** (default): update YAML only; leave tmux running. Useful when "stop" really means "I'm done with this card".
-- **hard stop**: `tmux kill-session` + update YAML. The default when the user says "kill it" or "end the session".
+The stop command is always **graceful by default**:
+1. Sends exit keys to the agent TUI (`/exit` for Claude, `Exit` for Agy) and waits 3 seconds.
+2. If still alive, issues `tmux kill-session` (SIGTERM) and waits 5 seconds.
+3. If still alive, kills the pane PID via SIGKILL (`kill -9`) as a last resort.
+4. Auto-captures the conversation ID into the row (`claude_session_id_own`/`agy_conversation_id_own`) before killing, ensuring the next resume uses a race-free tier-1 lookup.

-## Stop extension (Option A — `stop` semantics without a 6th skill)
-
-Rather than a separate `tmux-agent-orchestrate-stop` route, the base stop command absorbs the
-"stop" intent via three opt-in options. Passing **any** of them switches the YAML
-transition from `terminated` to **`stopped`** (`running → stopped`), signalling
-"deliberately stopped, conversation preserved, ready to resume":
-
-```bash
-# Stop: capture the conversation id into the row, record a reason, exit gracefully.
-bash skills/tmux-agent-orchestrate-stop/scripts/stop_session.sh \
-  --session "$SESSION_NAME" --capture-id --reason api_error --graceful
-```
-
-| Option | Effect |
-|---|---|
-| `--capture-id` | Before kill, resolve THIS workspace's conversation id via `find_workspace_uuid` (per-row → workspace-scoped disk scan → cache) and record it to `claude_session_id_own` / `agy_conversation_id_own`, plus `resumable: true`. Guarantees the next resume hits **tier-1** (race-free) instead of the mtime-based disk-scan fallback. |
-| `--reason <reason>` | Records `stop_reason` (default `manual_stop`). Convention: `user_request` / `api_error` / `timeout` / `crash` / `manual_stop`. |
-| `--graceful` | `tmux send-keys` exit (`/exit` for claude, `Exit` for agy) → 3 s wait → if alive `tmux kill-session` (SIGTERM) → 5 s → `kill -9` pane pid as last resort. Avoids hard-killing a TUI mid-write. |
-
-**Idempotency**: in STOP mode, if the row is already `status: stopped`, the script
-prints `already stopped (...)` and exits 0 — re-running is a safe no-op.
-
-**Backward compatibility**: with none of these options, the base stop command behaves exactly as
-before (`hard`→`terminated`, `soft`→`archived`).
+**Idempotency**: if the row is already `status: stopped`, the script prints `already stopped (...)` and exits 0 — re-running is a safe no-op.

+If `--purge-conversation` is used: `status: terminated`, `terminated_at`, `terminated_at_epoch`, `termination_mode: purge` and `resumable: false`.
 
 The script:
 1. Verifies the session is in agent-sessions.yaml
 2. If `delegate_job_id` is set, automatically publishes a `progress --detail "terminating"` event to the tmux-agent-orchestrate-delegate-job registry
 3. Captures the `last_visible_status` from `tmux capture-pane` (so we have a final TUI snapshot for audit)
-4. For `hard` mode: `tmux kill-session -t <name>` (which auto-SIGTERMs children including the agent)
+4. Attempts graceful exit keys → SIGTERM kill-session → SIGKILL fallback
 5. For `purge-conversation`: deletes `~/.claude/projects/.../jsonl` (claude) or `~/.gemini/antigravity-cli/conversations/...db` + `brain/...` (agy)
-6. Updates the YAML entry
+6. Updates the YAML entry and SQLite database atomically
 7. If `delegate_job_id` is set, publishes a `completed` event to the tmux-agent-orchestrate-delegate-job registry
-8. Updates the YAML entry:

-   - name: <SESSION_NAME>
-     status: terminated

-     terminated_at_epoch: ...
-     # all original fields preserved
-   ```
 
 ## Pitfalls
 
-- **`tmux kill-session` doesn't just kill the session — it sends SIGHUP to the pane's child processes too.** This is usually what you want (the agent process dies, no zombie reparenting to init). But if you wanted to keep the agent running outside tmux for some reason, use `soft` mode.
 - **Don't delete on-disk artifacts by default** — the agent's `*.jsonl` / `conversations/*.db` is the data that `tmux-agent-orchestrate-resume` needs. `--purge-conversation` is for when the user is genuinely done with the conversation and wants zero recovery chance.
-- **YAML is append-only until you write a stop** — if a previous run left the entry as `running` but tmux is actually dead (crash, host reboot), the YAML is stale. Running `tmux-agent-orchestrate-stop --mode hard` will detect "tmux already dead, just update YAML" and proceed.
-- **Don't delete the `claude_session_id_own: null` placeholder** — when the user creates a fresh session with `tmux-agent-orchestrate-create` and never sent a message, the entry has `claude_session_id_own: null`. Stopping must preserve that field (it's the audit trail showing "this tmux session never produced a session id of its own").
-- **Monitor skill may still be tracking** — if `tmux-agent-orchestrate-monitor` is running a heartbeat loop, stopping a session while it watches will trigger its `tmux ls != yaml` reconciliation. That's expected — let the monitor run, it will mark the entry as `terminated` on its own. Don't fight it.

 ## When NOT to use this skill
 
 - **Just detaching** → `tmux detach` (Ctrl-B d) or just close the terminal. The tmux session keeps running.
-- **Stopping the agent inside but keeping tmux** → send `Ctrl-C` or `/exit` (claude) / `Ctrl-D` (agy) via `tmux send-keys`. The tmux session stays but the agent process is gone; you can then `tmux-agent-orchestrate-create` again to spawn a fresh agent in the same tmux session.
-- **Replacing an existing session with a new one** → `tmux-agent-orchestrate-stop --mode hard` first, then `tmux-agent-orchestrate-create`.
