+## 2026-02-19: Split from core/go (Virgil)
+
+### Origin
+
+Extracted from `forge.lthn.ai/core/go` `pkg/store/` on 19 Feb 2026.
+
+### Architecture
+
+- SQLite database with WAL mode enabled for concurrent read performance
+- Compound primary key: `(group, key)` -- groups act as logical namespaces
+- UPSERT semantics on write (INSERT OR REPLACE)
+- Template rendering support via Go `text/template` for dynamic values
+- Pure Go SQLite driver via `modernc.org/sqlite` (no CGO required)
+
+### Dependencies
+
+- `modernc.org/sqlite` -- pure Go SQLite implementation
+
+### Tests
+
+- 1 test file covering CRUD operations, group isolation, and template rendering

+
+## Phase 1: TTL Support
+
+- [ ] Add optional expiry timestamp for keys
+- [ ] Background goroutine to purge expired entries
+- [ ] `SetWithTTL(group, key, value, duration)` API
+- [ ] Lazy expiry check on `Get` as fallback
+
+## Phase 2: Namespace Isolation
+
+- [ ] Group-based access control for multi-tenant use
+- [ ] Namespace prefixing to prevent key collisions across tenants
+- [ ] Per-namespace quota limits (max keys, max total size)
+
+## Phase 3: Event Hooks
+
+- [ ] Notify on `Set` / `Delete` for reactive patterns
+- [ ] Channel-based subscription: `Watch(group, key) <-chan Event`
+- [ ] Support wildcard watches (`Watch(group, "*")`)
+- [ ] Integration hook for go-ws to broadcast store changes via WebSocket

+## Workflow
+
+1. Virgil in core/go writes tasks here after research
+2. This repo's dedicated session picks up tasks in phase order
+3. Mark `[x]` when done, note commit hash
