feat(fusion_plating): partial order handling on the shop floor

Operators can now see and advance a job's parts across multiple stages
at once (e.g. 10 Masking / 20 Plating / 20 Baking on one 50-part job).
Tracking model C (fluid per-stage quantities + existing hold/scrap/
rework records for exceptions); board option 2 (a card per occupied
stage); wait-to-reconverge close. Additive only — no new model, no
migration, no change to the close/cert/ship lifecycle.

Board (fusion_plating_shopfloor/controllers/plant_kanban.py):
- One card PER (job, stage), composite key "{job_id}:{area}". Unsplit
  jobs render exactly as before. _job_presences/_render_presence;
  primary presence keeps full job card_state, secondary presences
  derive state from their focus step.

Card (plant_card.js/.xml/.scss):
- "20 of 50 here" badge; tap opens the workspace focused on that
  stage's step (focus_step_id, already accepted by the workspace).

Move + light-up (move_controller.py, fusion_plating_jobs/fp_job_step.py):
- Availability/pre-fill now from qty_at_step (step had no qty_done/
  qty_scrapped fields — the old read was always 0, dead path).
- Forward move auto-flips destination pending->ready (no auto-start;
  labour timer stays explicit) and auto-finishes a drained source
  (best-effort). Predecessor gate is qty-aware: a step with real
  arrived parts is startable regardless of upstream completion
  (_fp_has_real_incoming, single source of truth for can_start /
  blocker / button_start / move blockers).

Operator advance (job_workspace.js):
- "Send -> <next>" action on in_progress/paused steps opens the slimmed
  Move dialog (qty steppers, no keyboard; advanced fields collapsed).
  Was only wired into the deprecated shopfloor_tablet before.

Close (fp_job.py):
- button_mark_done counts move-based scrap (_fp_scrapped_via_moves) into
  qty_scrapped and derives qty_done = qty - scrapped (was blindly
  = job.qty, over-counting). Reconciliation gate unchanged.

Static-validated: pyflakes (py), lxml parse (xml), node --check (js).
Dynamic tests + browser check need an installed env (entech/trial) —
plating modules can't install on the local Community DB.

+## Partial Order Handling — parts fanning across stages (shipped 2026-06-02)
+
+A 50-part job can have parts at several stages at once (10 Masking, 20 Plating, 20 Baking). The data layer always supported this (`fp.job.step.qty_at_step` = live parked count, computed from `fp.job.step.move` rows); 2026-06-02 made it **visible and operable**. Spec: [`docs/superpowers/specs/2026-06-02-shopfloor-partial-order-handling-design.md`](docs/superpowers/specs/2026-06-02-shopfloor-partial-order-handling-design.md). Versions: `fusion_plating 19.0.22.2.0`, `fusion_plating_jobs 19.0.11.6.0`, `fusion_plating_shopfloor 19.0.36.2.0`. Tracking model = **fluid quantities per stage** for normal flow + existing hold/scrap/rework records for exceptions (no new model, no migration). Close behaviour = **wait to reconverge** (the lifecycle is unchanged; the diverged subset keeps the job open via the existing `qty_done + qty_scrapped == qty` gate).
+
+**Durable gotchas (non-obvious):**
+
+1. **The plant kanban emits one card PER (job, stage), keyed by a composite `"{job_id}:{area}"`** — NOT one card per job. `cards` is a dict of composite-key → presence payload; a split job lists its key in several `columns[].card_ids`. See `_job_presences` / `_render_presence` in `plant_kanban.py`. A job with all parts at one stage yields exactly ONE presence (identical to the old board). The PRIMARY presence (active-step column) keeps the full job-level `card_state`; SECONDARY presences derive a simpler state from their own focus step (`_secondary_card_state`). Anything reading the board payload must handle composite keys + multi-column jobs.
+
+2. **`fp.job.step` has NO `qty_done` / `qty_scrapped` fields.** Those live on `fp.job`. The Move controller previously read `from_step.qty_done - from_step.qty_scrapped` for "available to move" → always 0 → the partial-move path was effectively dead. The source of truth for "parts parked here" is **`qty_at_step`** (move preview/commit + rack moves all read it now). Never reintroduce `step.qty_done`.
+
+3. **The Move Parts dialog was only wired into the DEPRECATED `shopfloor_tablet.js`** — the live `fp_job_workspace` had no move/advance action, so operators literally could not move partial parts. The "Send → <next>" action now lives in `job_workspace.js` (`getStepActions` advance descriptor → `onAdvanceStep` → `FpMovePartsDialog`). The dialog itself was slimmed (qty steppers, no keyboard; Transfer Type + To Location collapsed behind "More options"). If you add another operator surface, wire the advance action there too.
+
+4. **Partial-flow "light up" lives in `move_controller._do_move_parts_commit` / `_do_move_rack_commit`:** a forward (`transfer_type='step'`) move (a) flips the destination step `pending → ready` so the receiving operator gets an actionable card with no action by anyone, and (b) calls `from_step._fp_try_autofinish_on_drain()` (best-effort, swallows finish-gate UserErrors). It does **not** auto-START the destination — `button_start` stays explicit to keep the labour timer accurate (S16). No auto-ready/auto-finish for hold/scrap/rework moves.
+
+5. **The predecessor gate is qty-aware: `_fp_should_block_predecessors()` returns False once `_fp_has_real_incoming()` is true** (an incoming move from a different step with `qty_moved > 0`). A step with parts physically parked at it is startable regardless of whether upstream steps are fully done. This is the single source of truth shared by `can_start`, `_compute_blocker`, `button_start`, and the Move dialog's `_blockers_for_move`. **Don't "fix" the predecessor gate back to pure sequence-based** — it would re-lock the next stage while the rest of the batch is still upstream.
+
+6. **Move-based scrap (`transfer_type='scrap'`) does NOT touch `job.qty_scrapped`.** At close, `button_mark_done` calls `_fp_scrapped_via_moves()` and folds it into `qty_scrapped`, then auto-fills `qty_done = qty − qty_scrapped` (was: blindly `= job.qty`, which over-counted when parts were scrapped). The reconciliation gate is still the safety net.
+
+**Verification:** the plating modules can't be installed on the local Community dev DB (missing enterprise deps — same reason `fusion_plating` shows `installed=0` in `modsdev`/`fusion-dev`). Static checks done: pyflakes (Python), lxml parse (XML), `node --check` as `.mjs` (JS — `node --check` on a `.js` errors with "Cannot use import statement outside a module"; copy to `/tmp/x.mjs` first). Dynamic tests + browser check require an installed env (entech / odoo-trial).
