` body in a box loop:
+
+```xml
+
+
+
+ ... existing structure ...
+
+
+```
+
+3. Change the Qty row's value column to show `X / N` when
+ `_qty_total > 1`:
+
+```xml
+
+ | Qty: |
+
+
+
+ /
+
+
+
+
+
+ |
+
+```
+
+**Outer templates supply `_qty_total`:**
+
+- SO outer: `_qty_total = line.product_uom_qty`
+- Job outer: `_qty_total = job.qty`
+
+If `_qty_total` is missing/zero, fall back to `1` so single-box
+behavior is unchanged.
+
+### Change 3 — Internal/External variants
+
+#### 3a. Inner template: override-or-fallback on `_notes_content`
+
+In `report_fp_wo_sticker_inner`, change the `_notes_content` set
+from a hard read to override-or-fallback (matches the existing
+pattern for `_so`, `_part`, etc.):
+
+```xml
+
+
+
+
+
+```
+
+External outer templates don't set `_notes_content` → falls through
+to `_line.name` (unchanged External behavior).
+
+Internal outer templates pre-set `_notes_content` before
+t-calling the inner:
+
+```xml
+
+```
+
+#### 3b. New outer templates + action records
+
+**SO Internal** — in `fusion_plating_reports/report/report_fp_wo_sticker.xml`:
+
+```xml
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+```
+
+**SO External** — existing `report_fp_so_sticker` template gets one
+addition: `
`.
+No other logic change (no `_notes_content` set = External default).
+
+**Job Internal** — in `fusion_plating_jobs/report/report_fp_job_sticker.xml`:
+
+```xml
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+```
+
+**Job External** — existing `report_fp_job_sticker_template`
+template gets one addition: `
`.
+
+**Action records — labels + new XML IDs**
+
+In `fusion_plating_reports/report/report_actions.xml`:
+
+```xml
+
+
+ External Sticker
+ ...
+
+
+
+
+ Internal Sticker
+ sale.order
+ qweb-pdf
+ fusion_plating_reports.report_fp_so_sticker_internal
+ fusion_plating_reports.report_fp_so_sticker_internal
+ 'Internal Sticker - %s' % (object.name or '').replace('/', '-')
+
+ report
+
+
+```
+
+In `fusion_plating_jobs/report/report_fp_job_sticker.xml`:
+
+```xml
+
+
+ External Job Sticker
+ ...
+
+
+
+
+ Internal Job Sticker
+ fp.job
+ qweb-pdf
+ fusion_plating_jobs.report_fp_job_sticker_internal_template
+ fusion_plating_jobs.report_fp_job_sticker_internal_template
+ 'Internal Job Sticker - %s' % (object.name or '').replace('/', '-')
+
+ report
+
+
+```
+

+
+## Migration
+
+None required.
+
+- **New grouping key (`_create_fp_jobs`)** is purely additive —
+ existing jobs are protected by the existing
+ `if existing: return` idempotency guard. Single-line and
+ same-(thickness, SN) multi-line SOs collapse identically to
+ before.
+- **Existing XML IDs unchanged** — bookmarks / `binding_model_id`
+ records keep working. Only the visible label flips.
+- **New variants** appear in the Print menu on next module
+ upgrade with no data work.
+
+## Testing
+
+### Scenario 1 — Multi-thickness split (new fp.jobs)
+
+Create a new SO with two lines:
+- Line 10: Part A, Coating X, Thickness 0.3-0.5 mils, qty 2
+- Line 20: Part A, Coating X, Thickness 0.5-1.0 mils, qty 1
+
+Confirm SO → 2 fp.jobs are created:
+- `WO-XXXXX-01`: qty 2, thickness 0.3-0.5
+- `WO-XXXXX-02`: qty 1, thickness 0.5-1.0
+
+Print each job's External sticker → confirm correct thickness on each.
+
+### Scenario 2 — Per-box rendering
+
+Take Scenario 1's SO, click "Print → External Sticker" on the SO.
+
+Confirm: 3-page PDF.
+- Page 1: Line 10 box 1 → Qty row shows `1 / 2`
+- Page 2: Line 10 box 2 → Qty row shows `2 / 2`
+- Page 3: Line 20 box 1 → Qty row shows `1`
+
+### Scenario 3 — Internal variant
+
+On the same SO, click "Print → Internal Sticker".
+
+Confirm: same 3 pages, same WO#/PO#/Customer/Part#/SN/Thickness/Qty,
+but the Notes column shows `x_fc_internal_description` from each
+line instead of `name`.
+
+If `x_fc_internal_description` is blank on a line, Notes shows `-`.
+
+### Scenario 4 — Regression check (existing single-line)
+
+Re-print SO-30019 (1 line, qty 1) → External sticker prints
+single-page, no `X / N` indicator, Notes shows `_line.name` as
+before. Internal variant: single-page, Notes shows `x_fc_internal_description`
+or `-`.
+
+### Scenario 5 — Job-level multi-box
+
+Take any existing fp.job with `qty = 3`. Print External Job Sticker.
+
+Confirm: 3 pages, `1/3`, `2/3`, `3/3`. Internal Job Sticker also 3
+pages with the line's internal description in Notes.
+
+### Scenario 6 — Action menu visibility
+
+On a sale order Print menu: both "External Sticker" and
+"Internal Sticker" appear. On an fp.job Print menu: both
+"External Job Sticker" and "Internal Job Sticker" appear.
+
+## Out-of-scope items (deferred)
+
+- **Per-box SN registry.** Today `x_fc_serial_id` is one per line.
+ If the customer needs unique SNs per physical box (5 parts =
+ 5 SNs), build out an `fp.box.serial` registry that links to the
+ line. Out of scope for this spec — would need workflow design
+ (UI for assigning, where SNs print, etc.).
+- **Box count ≠ qty.** Some shops pack multiple parts per box.
+ Today this spec assumes 1 sticker per qty unit. If needed,
+ add an `x_fc_box_count` field on the line that defaults to qty
+ but can be overridden, and the sticker loops over box_count
+ instead. Defer until requested.
+- **Sticker preview UI in the form view.** No live preview today;
+ operators print + visually verify. Defer.
+
+## Open questions
+
+None — all decisions locked at spec time:
+
+| Q | Decision |
+|---|---|
+| Add SN to grouping key? | **Yes.** Same reasoning as thickness — silent merge of different SNs is a compliance hole. |
+| Per-box indicator location? | **Replace Qty row value.** Operator's confirmation: "we can use the quantity field portion for the box, there is room we can use rather than creating another line below and making everything smaller." |
+| Box indicator format? | **`1 / 5`** (slash, spaces around for legibility at 50pt). When qty=1, show plain `1` (no slash) — matches current behavior. |
+| Label naming convention? | **Prefix.** `External Sticker` / `Internal Sticker` (SO Print menu), `External Job Sticker` / `Internal Job Sticker` (fp.job Print menu). |
+| Migration for existing jobs? | **None.** Idempotency guard in `_create_fp_jobs` protects them. |
+| Existing action XML IDs? | **Unchanged.** Only labels rename — bookmarks/binding records survive. |
+| Fractional qty? | Cast to `int(qty)` — current behavior preserved. |
+| Qty=0 line? | Already filtered out by `lambda l: l.x_fc_part_catalog_id` (no part → no sticker). |
