# Technician (Mobile) — Developer Task Breakdown

> Source-of-truth task list for the Technician slot (dev-mode v1.0, CL-2). One row per screen + the shared dependencies. Surface = Flutter mobile portrait.
> **Team for this slot:** Mobile (Flutter) FE + Backend (shared with the Maintenance TL pack + WorkOrder foundation) + Tester. No web-FE (mobile-primary role).
> **Priority:** P0 (must-ship Phase 1) · P1 (nice-to-have).
> **Dependencies** are topological — build in order. Foundation (Wave 0) precedes everything: schema (incl. `WorkOrder` / `WorkOrderEvent` / `WorkOrderPhoto`), auth, runtime RBAC resolver, WO state machine, parent `HELD` release logic, `/me`, photo endpoint, Flutter DS parity, generated Dart models.

| Backend tasks | `GET /me/work-orders?state=` (own assignments, own GZ; stored WO state per row; SLA computed). |

### TECH-WO-DONE — Mark Done (fixed) (CRITICAL)

| States / sheets | `bottom-sheets/photo-capture.html`, `bottom-sheets/confirm-done.html`, `states/offline.html` |
| Dependencies | TECH-WO-DETAIL; photo endpoint (Wave 0); parent `HELD` release logic |
| Mobile-FE tasks | Fix-note textarea; **mandatory fix-photo** `PhotoUpload` tile → photo-capture sheet; camera FAB; multipart upload via `PhotoRepository` (`kind=COMPLETION`, `workOrderId`); **gate Mark Done client-side** until ≥1 photo; confirm-done sheet (states "closes at maintenance"); `PATCH …/done` (If-Match); handle 422 (no photo); **online-only: hold draft in memory + retry**; on success route to status / list. |
| Backend tasks | `POST /uploads/photos` (multipart → **local disk**, `sharp` thumb, `WorkOrderPhoto` row); `DELETE /uploads/photos/:id`; `PATCH …/done` — **re-check photo gate (422 if no `WorkOrderPhoto`)**; `IN_PROGRESS→DONE`; `closedAt`; `WorkOrderEvent`; compute parent `HELD` release on last open WO (no SM notify); audit. |

| Backend tasks | `GET /me/profile`; `POST /auth/logout`; `GET /me/notifications` + read. |
| Pri | P0 |

## Build order (topological)
1. **(Wave 0 / Foundation)** auth, `/me`, RBAC resolver, schema (incl. `WorkOrder`/`WorkOrderEvent`/`WorkOrderPhoto`), WO state machine, parent `HELD` release logic, photo endpoint, Flutter DS, Dart models.
2. `AUTH-LOGIN` → `TECH-DASH` (shell + role-resolve).
3. `TECH-WO-TODAY` → `TECH-WO-DETAIL` → `TECH-WO-DONE` / `TECH-WO-RETURN` (the maintenance flow — depends on the WO endpoints + photo endpoint; pairs with `maintenance-tl-web` assign/review).
4. `SH-PROFILE` (independent; can run in parallel).

> The slot demo gate: **Suresh logs in → opens an assigned WO → Starts → tries Done blocked (no photo) → shoots a fix photo → Done passes → action closes at maintenance + parent checklist releases from Held; and on a different WO → Return blocked (no reason) → enters reason → Return passes → Maintenance TL notified.** When that closes end-to-end against real APIs (paired with `maintenance-tl-web`), the Technician slot is DONE.
