refactor: address PR review — rename, move helpers, add migration runner

Per review #320 comments:

- Rename _sv() → get_supervise_mod() in both store files (review 206/211)
- Move _audit_entry_from_row onto AuditStore as _row_to_entry static method
  (review 208); move _proposal/_response_from_row onto QueueStore (review 211)
- Remove _host_db_path() free function; inline into __init__ (review 209/211)
- Add stdlib migration runner using a shared schema_versions table; each store
  tracks its own version under a module key so they can coexist in the same DB
  without clobbering a shared PRAGMA user_version (reviews 210/212/213)
- PRD: add goal 6 (migration runner), narrow non-goal to third-party ORM only

+# PRD prd-new: SQLite local storage
+
+- **Status:** Active
+- **Author:** codex
+- **Created:** 2026-07-01
+- **Issue:** #319
+
+## Summary
+
+Add a small stdlib SQLite storage layer for bot-bottle host runtime state,
+starting with the supervise queue and audit log. This replaces scattered JSON
+queue files and JSONL audit logs with structured tables while preserving the
+existing public supervise helper functions and sidecar queue mount contract.
+
+## Problem
+
+Bot-bottle currently stores supervise proposals and responses as individual JSON
+files under `~/.bot-bottle/queue/<slug>/`, and audit entries as JSONL files
+under `~/.bot-bottle/audit/`. That worked for the original interactive TUI, but
+new forge-native orchestration needs durable, queryable local state for queues,
+audit trails, watchdogs, and lifecycle records. PR #318 started introducing
+SQLite-shaped boilerplate for forge state; the storage foundation should live in
+its own PR so forge work can build on the shared runtime store instead of adding
+one-off persistence.
+
+## Goals / Success Criteria
+
+1. Supervise proposals and responses are persisted through SQLite.
+2. Audit entries are persisted through SQLite.
+3. Supervise queue helpers use the bottle slug / queue key instead of a queue
+   directory path.
+4. The sidecar receives the host database mount across docker, smolmachines,
+   and macOS-container backends.
+5. The implementation stays stdlib-only.
+6. Schema migrations use a `PRAGMA user_version` runner — no third-party deps.
+7. Unit tests cover queue round-trips, pending discovery, response waits,
+   archive semantics, audit round-trips, and path creation.
+
+## Non-goals
+
+- Migrating old JSON queue files or JSONL audit logs.
+- Adding forge orchestration state tables.
+- Adding egress metering or budget tables.
+- Changing the supervise TUI workflow or remediation behavior.
+- Introducing a third-party ORM or migration library.
+
+## Design
+
+### Database locations
+
+Queue and audit state use the host-level local database:
+
+```text
+~/.bot-bottle/bot-bottle.db
+```
+
+The supervise sidecar receives that database as a writable bind mount at
+`/run/supervise/bot-bottle.db` and gets the path through `SUPERVISE_DB_PATH`.
+No per-slug queue directory is mounted into the sidecar. This creates the shared
+host database that later forge/native lifecycle work can extend in separate
+PRDs.
+
+### Tables
+
+`supervise_proposals` lives in the host database:
+
+```sql
+CREATE TABLE supervise_proposals (
+    queue_key TEXT NOT NULL,
+    id TEXT NOT NULL,
+    bottle_slug TEXT NOT NULL,
+    tool TEXT NOT NULL,
+    proposed_file TEXT NOT NULL,
+    justification TEXT NOT NULL,
+    arrival_timestamp TEXT NOT NULL,
+    current_file_hash TEXT NOT NULL,
+    archived INTEGER NOT NULL DEFAULT 0,
+    PRIMARY KEY (queue_key, id)
+);
+```
+
+`supervise_responses` lives in the host database:
+
+```sql
+CREATE TABLE supervise_responses (
+    queue_key TEXT NOT NULL,
+    proposal_id TEXT NOT NULL,
+    status TEXT NOT NULL,
+    notes TEXT NOT NULL,
+    final_file TEXT,
+    archived INTEGER NOT NULL DEFAULT 0,
+    PRIMARY KEY (queue_key, proposal_id)
+);
+```
+
+`supervise_audit_entries` lives in the host database:
+
+```sql
+CREATE TABLE supervise_audit_entries (
+    id INTEGER PRIMARY KEY AUTOINCREMENT,
+    timestamp TEXT NOT NULL,
+    bottle_slug TEXT NOT NULL,
+    component TEXT NOT NULL,
+    operator_action TEXT NOT NULL,
+    operator_notes TEXT NOT NULL,
+    justification TEXT NOT NULL,
+    diff TEXT NOT NULL
+);
+```
+
+### Compatibility
+
+The queue helpers take a bottle slug / queue key and perform equivalent
+operations against `~/.bot-bottle/bot-bottle.db`:
+
+- `list_pending_proposals` returns non-archived proposals without a non-archived
+  response, sorted by arrival time.
+- `archive_proposal` marks matching proposal/response rows archived instead of
+  moving files into `processed/`.
+- `wait_for_response` keeps the current polling behavior but polls SQLite.
+
+The old audit path helpers (`audit_dir`, `audit_log_path`) stay available for
+compatibility. `audit_log_path` no longer describes the active storage location;
+callers should use `read_audit_entries`.
+
+## Implementation chunks
+
+1. Add SQLite store helpers for supervise queue and audit state.
+2. Rewire `bot_bottle.supervise` queue/audit functions to the store.
+3. Update supervise CLI discovery tests and queue/audit unit tests.
+4. Run unit tests, pyright, and pylint for touched modules.
+
+## Open questions
+
+None.
