Locale propagated via `store.WithLocale(ctx)` — WS `connect` param `locale`, HTTP `Accept-Language` header. Supported: en (default), vi, zh. New user-facing strings: add key to `internal/i18n/keys.go`, add translations to all 3 catalog files. New UI strings: add key to all 3 locale dirs. Bootstrap templates (SOUL.md, etc.) stay English-only (LLM consumption).

 - Use `append(dst, src...)` instead of loop-based append
 - Always handle errors; don't ignore return values
 - **Migrations (dual-DB):** PostgreSQL and SQLite have **separate migration systems**. When adding schema changes: (1) PG: add SQL in `migrations/` + bump `RequiredSchemaVersion` in `internal/upgrade/version.go`. (2) SQLite: update `internal/store/sqlitestore/schema.sql` (full schema for fresh DBs) + add incremental patch in `schema.go` `migrations` map + bump `SchemaVersion` constant. **Always update both** — missing SQLite migrations cause desktop edition to crash on startup
-- **i18n strings:** When adding user-facing error messages, add key to `internal/i18n/keys.go` and translations to `catalog_en.go`, `catalog_vi.go`, `catalog_zh.go`. For UI strings, add to all locale JSON files in `ui/web/src/i18n/locales/{en,vi,zh}/`

 - **SQL safety:** When implementing or modifying SQL store code (`store/pg/*.go`), always verify: (1) All user inputs use parameterized queries (`$1, $2, ...`), never string concatenation — prevents SQL injection. (2) Queries are optimized — no N+1 queries, no unnecessary full table scans. (3) WHERE clauses, JOINs, and ORDER BY columns use existing indices — check migration files for available indexes
 - **DB query reuse:** Before adding a new DB query for key entities (teams, agents, sessions, users), check if the same data is already fetched earlier in the current flow/pipeline. Prefer passing resolved data through context, event payloads, or function params rather than re-querying. Duplicate queries waste DB resources and add latency
 - **Solution design:** When designing a fix or feature, identify the root cause first — don't just patch symptoms. Think through production scenarios (high concurrency, multi-tenant isolation, failure cascades, long-running sessions) to ensure the solution holds up. Prefer explicit configuration over runtime heuristics. Prefer the simplest solution that addresses the root cause directly
