# Session: 2026-06-24 — Phase 3b·2 (Reports + all-users export)

## Goal

Give the admin a **Rapporten** screen: pick a period (Deze week / Deze maand / Alles + manual
from/to) and optionally narrow by worker / insole type / activity, see headline production totals
plus three breakdowns (per medewerker / per handeling / per type), and export the underlying
detail rows (all workers) to CSV. Today's `/api/export` is **self-scoped** to the logged-in user;
this cycle adds the cross-user, filterable reporting + export. Second of three Phase 3b cycles
(after manual-sessions 3b·1; user management remains).
Spec: `docs/superpowers/specs/2026-06-24-phase-3b2-reports-export-design.md`;
plan: `docs/superpowers/plans/2026-06-24-phase-3b2-reports-export.md`.
Tracked as Plane epic **SL-48** with tasks **SL-49…SL-53**.

## Scope decisions (brainstorming)

- **Both lenses on one screen** (totals + breakdowns per worker AND activity AND type).
- **Filters:** date range (spine) + optional worker + type + activity; default **this week**.
- **Completed-only** counts toward totals/export (active/discarded excluded).
- **All four metrics:** gewerkte tijd, aantal zolen, aantal sessies, pauzetijd.
- **CSV = detail rows, all workers** (a leading Worker column), not the aggregated summary.
- **Tables only** — no chart library, no CSS bars (dependency-light).

## Work done

Built via a 5-task TDD **Workflow** (`w7ut902zo`), one commit per task, run sequentially because the
tasks share one working tree:

- **Task 1 — DRY CSV builder** (`01fa18f`). Extracted the inline header/row builder from the
  self-scoped `/api/export` into `buildSessionsCsv(rows, { includeWorker })` + a `SessionCsvRow`
  interface in `apps/api/src/lib/csv.ts`. `sessions.ts` now maps its query rows into `SessionCsvRow`
  and calls the shared builder. `includeWorker:false` keeps the worker export **byte-identical**
  (the existing `export.test.ts` is the regression guard); `includeWorker:true` prepends a Worker
  column. New `csv.test.ts` covers both header variants.
- **Task 2 — Report contracts + `GET /api/admin/report`** (`4b213e2`). Added `ReportTotals`,
  `ReportWorkerRow`, `ReportActivityRow`, `ReportTypeRow`, `ReportResponse` to `@solelog/shared`.
  In `admin.ts`: `parseReportQuery` (validates `from`/`to` range, `insole_type`, `activity_id`),
  `buildSessionFilters` (completed-only + date range + optional worker/type/activity), and the
  report route — fetches the filtered joined rows and aggregates `totals` + `by_worker`/
  `by_activity`/`by_type` in JS (sorted by `worked_seconds` desc; empty range → zeros + empty
  arrays; null type bucketed under "Onbekend"). `report.test.ts` (5 cases).
- **Task 3 — `GET /api/admin/export`** (`d33fcb7`). All-users filtered CSV reusing
  `parseReportQuery` + `buildSessionFilters` (Task 2) and `buildSessionsCsv(includeWorker:true)`
  (Task 1); ordered by `start_time` asc; filename `solelog-report_<from>_<to>.csv`. 401/403 inherited
  from the `/api/admin/*` guard. Export tests appended to `report.test.ts`.
- **Task 4 — Admin API client** (`8ad2e69`). `apps/admin/src/api/reports.ts`: `ReportFilters`,
  `filtersToQuery` (omits empty optionals), `useReport` (React Query), and `downloadExport` — a raw
  `fetch` with the bearer token → `Blob` → object-URL download (a plain `<a href>` can't carry the
  token). `reports.test.ts` covers serialization + the bearer-fetch download + non-ok throw.
- **Task 5 — Rapporten screen + nav** (`8d75be0`). Pure `lib/date-range.ts` helpers (`thisWeek`,
  `thisMonth`, `allTime`, `dayStartISO`/`dayEndISO` — local-day → ISO instants so there's no server
  tz ambiguity) with unit tests. `screens/Reports.tsx`: filter bar (presets + date inputs + worker/
  type/handeling dropdowns), a headline totals line, and three breakdown tables, plus the
  **Exporteer CSV** button wired to `downloadExport`. Sidebar moves **Rapporten** into `navItems`
  (soon = just `Gebruikers`); `App.tsx` gets the `/rapporten` route; report styles appended to
  `styles.css`.

## Deviations (fix-forward, test-only)

- **Task 3:** the API test DB is reset once per file (`test/setup.ts`), so the WIDE-window export
  tests initially picked up sessions seeded by the earlier report tests. Fixed by scoping the two
  non-gating export tests to their own freshly-seeded activity via `&activity_id=…` (a real filter
  the route already supports). The route code is exactly as planned.
- **Task 5:** the plan's `Reports.test.tsx` had a few assertions that collided with the screen's own
  markup (headline `36` vs a table cell; `Jan`/`Kurk` matching dropdown `<option>`s). Tightened three
  assertions (scope to `.reports-totals`; target `getByRole('cell', …)`) and loosened the apiFetch
  mock signature for a teardown refetch. Screen behavior/markup unchanged.

## Verification (independent of the workflow's self-reports)

- `git log` — five task commits `01fa18f → 8d75be0`; **clean tree**.
- `yarn workspace @solelog/api test` — **85 passed** (14 files), incl. `csv`, `report`, and the
  unchanged regression `export.test.ts`; `typecheck` clean.
- `yarn workspace @solelog/admin test` — **46 passed** (10 files), incl. `reports`, `date-range`,
  `Reports`; `typecheck` clean; `build` succeeds (vite, 94 modules).
- `npx oxlint` — clean (exit 0).

## Outcome

Phase 3b·2 is implemented and green across both touched workspaces. An admin opens **Rapporten**,
picks a period + optional filters, and sees correct headline totals (worked / zolen / sessies /
pauze) with three breakdown tables, then exports every matching completed session (all workers, with
a Worker column) to a range-named CSV. One CSV format now serves both the worker self-export and the
admin export. No DB migration (reuses existing `work_sessions` columns). Plane SL-48 + SL-49…SL-53
all marked Done. Roadmap Phase 3 note updated: **3b·2 done; user management is the last 3b cycle.**

The maintainer's deploy WIP (`.env.prod.example` / `docker-compose.prod.yml`) was left untouched.
`origin/main` is **behind** (the pre-compaction push never landed); after this cycle `main` is ahead
**~16** commits — a single `git push origin main` from the maintainer's terminal carries the batch
(and triggers Gitea CI).

## Next (Phase 3b remainder)

- **User management** — create / set role / deactivate via better-auth `/api/auth/admin/*` (the
  `Gebruikers` screen). Final 3b cycle.
