# Scratchpad — P5-001 Plugin Host

- Task: P5-001 / issue #41
- Branch: feat/p5-plugin-host
- Objective: add global NestJS plugin host module, wire Discord import, register active plugins from env, and attach to AppModule.
- TDD: skipped as optional for module wiring/integration work; relying on targeted typecheck/lint and module-level situational verification.
- Constraints: ESM .js imports, explicit @Inject(), follow existing gateway patterns, do not touch TASKS.md.

## Progress Log

- 2026-03-13: session started in worktree; loading gateway/plugin package context.
- 2026-03-13: implemented initial plugin module, service, interface, and AppModule wiring; pending verification.
- 2026-03-13: added `@mosaicstack/discord-plugin` as a gateway workspace dependency and regenerated `pnpm-lock.yaml`.
- 2026-03-13: built gateway dependency chain so workspace packages exported `dist/*` for clean TypeScript resolution in this fresh worktree.
- 2026-03-13: verification complete.
