"id": "KB-310",
"title": "Migrate from file-based storage to SQLite (hybrid: DB for metadata, files for blobs)",
"description": "Migrate the kb task board system from its current file-based storage (task.json, config.json, JSONL logs) to a SQLite database at `.kb/kb.db`, using Node.js built-in `node:sqlite` (experimental, Node 22.5+).\n\n## Strategy\n\n**Hybrid approach:** All structured/queryable metadata moves to SQLite. Large blob files (`PROMPT.md`, `agent.log`, attachments) remain on the filesystem under `.kb/tasks/{ID}/`.\n\n## Stores to Migrate\n\nAll six data stores will be migrated:\n\n1. **Tasks** — `task.json` → `tasks` table. Scalar fields (id, title, column, status, size, timestamps, model overrides, etc.) as proper columns. Nested/array data (steps, dependencies, log, prInfo, issueInfo, attachments metadata, steeringComments, workflowStepResults) as JSON text columns. Task directories still hold `PROMPT.md`, `agent.log`, and `attachments/` files.\n2. **Board config & project settings** — `config.json` → `config` table (key-value or single-row). Includes nextId counter, project settings, workflow step definitions, and nextWorkflowStepId.\n3. **Activity log** — `activity-log.jsonl` → `activity_log` table with indexed `timestamp` and `type` columns for efficient filtered queries.\n4. **Archive log** — `archive.jsonl` → `archived_tasks` table with indexed `id` for instant lookups instead of linear JSONL scans.\n5. **Automations** — `automations/*.json` → `automations` table.\n6. **Agent store** — Agent records, heartbeat events, and runs → `agents`, `agent_heartbeats`, `agent_runs` tables.\n\n## Schema Approach\n\nJSON columns for nested arrays/objects, flat columns for scalar fields. Leverage SQLite's `json_extract()` for any queries into JSON columns. This keeps the schema simple, closely mirrors the current data shape, and makes migration straightforward.\n\n## SQLite Library\n\nNode.js built-in `node:sqlite` (available since Node 22.5+). Zero external dependencies. Synchronous API simplifies the current promise-chain locking model — `withTaskLock()` and `withConfigLock()` can be replaced with synchronous transactions.\n\n## Migration & Backward Compatibility\n\n**Auto-migrate on first run:** During `init()`, detect if `.kb/kb.db` is missing but old file-based data exists. Automatically import all tasks, config, logs, archive, automations, and agents into SQLite. Preserve old files as backup (e.g. `.kb/tasks.bak/`, `.kb/config.json.bak`). Seamless upgrade — no user action required.\n\n## External Change Detection\n\n**SQLite change polling:** Replace the current `fs.watch()` watcher with periodic SQLite polling (e.g. check a `last_modified` / change counter). Handles multi-process scenarios where the dashboard and engine may both access the DB. The existing event emission pattern (`task:created`, `task:moved`, `task:updated`, `task:deleted`) is preserved.\n\n## Packages Affected\n\n- **`@kb/core`** — Primary target. Rewrite `TaskStore`, `AgentStore`, `AutomationStore`, `GlobalSettingsStore`. New `Database` module for SQLite connection management, schema creation, and migration logic.\n- **`@kb/dashboard`** — API routes should need minimal changes (they call TaskStore methods which keep the same signatures). SSE bridge updated to work with polling-based change detection.\n- **`@kb/engine`** — Agents call TaskStore/AgentStore methods — no changes expected if method signatures are preserved.\n- **`@dustinbyrne/kb`** — CLI and pi extension call TaskStore directly — same story, method signatures preserved.\n\n## Key Risks\n\n- `node:sqlite` is experimental — API may change in future Node versions\n- Requires Node 22.5+ minimum version\n- SQLite WAL mode needed for concurrent reader/writer access (dashboard + engine)\n- Migration must handle partial/corrupt legacy data gracefully",

"summary": "Migrated kb task board system from file-based storage to hybrid SQLite + filesystem architecture. Created Database module (packages/core/src/db.ts) with WAL mode, nested transaction support via savepoints, and monotonic change detection timestamps. Created migration system (packages/core/src/db-migrate.ts) that auto-detects legacy data and migrates config, tasks, activity log, archive, automations, and agents to SQLite while preserving blob files (PROMPT.md, agent.log, attachments) on disk. Refactored TaskStore and AutomationStore to use SQLite as primary store with backward-compatible disk writes. All 419 tests pass across 7 test files (54 new db.ts tests, 25 new migration tests, 256 store tests, 48 automation tests unchanged)."
