test(db): resolve the integration DSN at run time instead of storing an IP (#161)
setup-test-db.sh wrote .env.test once with the Postgres container's bridge IP
baked in, and Docker reassigns those on recreation. The file rotted silently:
its stored 172.22.0.18 belongs to **gitea** as of today, and an earlier drift
had the suite pointing its TRUNCATE at **postgres-pantry** — which it would
have wiped had the credentials happened to match.

Root-cause fix: stop persisting a host at all.

- scripts/resolve-test-db.sh re-derives the DSN from the live container and
  rewrites .env.test. Resolution order is TEST_DATABASE_URL, then the
  container's published host port, then the bridge IP. `docker port
  postgres-personal` reports 127.0.0.1:5432 since the 2026-08-17 PG17
  migration, so loopback is what gets used here — and a loopback address
  cannot be reassigned to another container, which is the whole point.
  (Note this supersedes the smarthome CLAUDE.md's "postgres-personal publishes
  no host port"; that is now stale.) The bridge-IP fallback is kept for a host
  where the port is not published, and the script never prints the password.
- Wired as `pretest:integration`, so npm runs it before every integration run.
  .env.test becomes a generated artifact rather than stored configuration.
- setup-test-db.sh now only creates the database and copies the schema, then
  delegates to the resolver.
- helpers.ts::assertTestDatabase stays and its message now points at the
  resolver rather than at `docker inspect`. It still earns its place: running
  vitest directly bypasses the pretest hook, and a stale .env.test would then
  still be read.

Docs: CLAUDE.md gains a Testing section carrying this, the prisma-generate
trap for a fresh checkout or worktree, and the frozen-clock rule for tests
whose subject is defined relative to "now". AGENTS.md updated for the same, and
for lint now being blocking.

# Repository Guidelines
## Project Structure & Module Organization
Application code lives in `src/`. Next.js App Router pages and API route handlers belong in `src/app/`; reusable UI components are in `src/components/`; database access, query functions, hooks, authentication, and domain helpers are in `src/lib/`. Tests are separated into `src/__tests__/unit/` and `src/__tests__/integration/`. PostgreSQL schema and numbered SQL migrations live under `prisma/`, static assets under `public/`, operational scripts under `scripts/`, and design notes under `docs/`.
Keep data flow consistent: API routes call query functions in `src/lib/queries.ts`, which use `queryRaw()` from `src/lib/db.ts`; client components access APIs through TanStack Query hooks in `src/lib/hooks.ts`.
**Task tracking is the Vikunja board at `https://tasks.bosecamp.com`** (project *Work*, saved filter **finance-app**), which replaced the smarthome repo's `ACTIONS.md` on 2026-07-30. Update the ticket in the same change as the code. See `CLAUDE.md` → "Work tracking".
## Build, Test, and Development Commands
- `npm ci` installs the locked dependency set (Node 22 is used in CI).
- `npm run dev` starts the local Next.js development server.
- `npm run build` creates a production build; `npm start` serves it.
- `npm run lint` runs the Next.js ESLint configuration. **Blocking in CI since #79** — the pre-existing debt is cleared, so it must stay at zero errors (warnings are still allowed).
- `npx tsc --noEmit` typechecks, including the test files. Also blocking in CI.
- `npm test` runs fast unit tests.
- `npm run test:setup` creates/refreshes the `personal_test` database (run it once, and after any migration).
- `npm run test:integration` runs database-backed tests. It re-resolves the DSN from the live container first (`scripts/resolve-test-db.sh`), so `.env.test` must never carry a hand-written host — see `CLAUDE.md` → Testing.
- `npm run test:all` runs both test suites.
## Coding Style & Naming Conventions
Use strict TypeScript, two-space indentation, semicolons, and double quotes, matching existing files. Name React components and types in PascalCase, functions and variables in camelCase, and files/routes in kebab-case. Use the `@/` alias for imports from `src/`. Preserve owner scoping and prefer transaction overrides with `COALESCE` in financial queries. Every API route must authenticate before accessing data.
## Testing Guidelines
Vitest is the test framework. Name tests `*.test.ts` and place pure logic tests under `unit/`; put PostgreSQL-dependent behavior under `integration/`. Add regression coverage for query, rule, reconciliation, and category changes. No numeric coverage threshold is configured; focus on meaningful edge cases and run `npm run test:all` before submitting database-related changes.
## Database, Security & Configuration
Add schema changes as the next numbered `prisma/migrations/NNNN_description/migration.sql`. Never commit `.env`, `.env.test`, raw statements in `dump/`, or other financial data. Consult `CLAUDE.md` and relevant `docs/` notes before changing splits, settlements, loans, reconciliation, or statement accounting.
## Commits & Pull Requests
History follows concise Conventional Commit-style subjects such as `feat(rules): preview rule changes`, `fix(trips): ...`, and `docs: ...`. Keep commits focused. Pull requests should explain behavior and data-model impact, link related issues, list validation commands, and include screenshots for UI changes. Ensure lint, typecheck, unit tests and the production build pass; call out any migration steps.
