# Task Scratchpad — Turbo DATABASE_URL passthrough

## Objective

- Fix CI test execution under Turborepo by passing DB-related environment variables through the `test` task.
- Preserve the repo's documented local Postgres fallback on host port `5433`.

## Scope

- Edit `turbo.json`
- Run baseline checks requested by the user and repo rules where feasible
- Publish branch and open PR if checks are acceptable

## Assumptions

- ASSUMPTION: No PRD update is required because this is a narrow CI/config bug fix that does not change product requirements.
- ASSUMPTION: `docs/TASKS.md` remains untouched because project guidance marks it orchestrator-only.
- ASSUMPTION: Local Postgres-backed tests are not runnable in this worktree, so baseline verification will rely on static gates unless the environment already provides DB access.

## Plan

- Record current repo state and avoid touching `.mosaic/orchestrator/session.lock`
- Add Turbo DB env declarations for test execution and cache invalidation
- Run `pnpm format:check`, `pnpm typecheck`, and `pnpm lint`
- Review the diff, then commit/push/PR via provider-appropriate flow

## Verification Log

- `pnpm install` completed in this worktree so repo tooling is available
- `pnpm format:check` initially failed on `turbo.json`; fixed by formatting the file
- `pnpm format:check` passed after formatting
- `pnpm typecheck` passed
- `pnpm lint` passed
- Independent review flagged two important adjustments:
  - keep `DEFAULT_DATABASE_URL` on `5433` because local Docker Compose maps host `5433 -> container 5432`
  - prefer Turbo `env` over `passThroughEnv` so DB config changes also affect the test cache key

## Risks

- Existing mission/orchestrator files are dirty in the worktree and must be excluded from the scoped change.
- Local tests were not run because no Postgres service is available in this worktree; CI remains the primary situational validation for the test-task behavior.
