Menu Structure (Plating App)

The Plating app (menu_fp_root, seq 46) has these top-level menus:

Seq	Menu	Module	Children
3	KPIs	fusion_plating_kpi	KPIs, KPI History, Production/Quality/Finance dashboards
5	Sales	fusion_plating_configurator + portal	Quotations, Sale Orders, Customers, Part Catalog, Quote Requests, Portal Jobs
8	Configurator	fusion_plating_configurator	New Quote, Coating Configs, Pricing Rules, Treatments
12	Shop Floor	fusion_plating_shopfloor	Plant Overview, Tablet Station, Bake Windows, First-Piece Gates
15	Receiving	fusion_plating_receiving	All Receiving, Pending Inspection, Discrepancies
18	Operations	fusion_plating (core)	Process Recipes, Production Priorities (bridge_mrp), Batches (batch), Baths, Chemistry Logs, Tanks
25	Certificates	fusion_plating_certificates	All, CoC, Thickness Reports
30	Quality	fusion_plating_quality	Holds, NCRs, CAPAs, FAIR, Audits, Doc Control
40	Compliance	fusion_plating_compliance	Permits, Discharge, Waste, Calendar, Spills, Config
45	Safety	fusion_plating_safety	SDS, Training, Exposure, JHSC, Incidents, PPE
50	Logistics	fusion_plating_logistics + fusion_tasks	Pickups, Deliveries, Routes, CoC, POD, Field Tasks, Task Map, Task Calendar
60	Aerospace	fusion_plating_aerospace	AS9100, Nadcap, Counterfeit, Config Items, Risk
65	Nuclear	fusion_plating_nuclear	Program, ITP, 10CFR21, Pedigree, CNSC
70	CGP	fusion_plating_cgp	Registration, AI, PSA, Visitors, Goods, Shipments, Security, Access Log
80	Culture	fusion_plating_culture	Values, Recognitions — RETIRED, uninstalled on entech, code kept in repo only
90	Configuration	fusion_plating (core) + many	Facilities, Work Centres, Process Categories/Types, Bath Params, Stations, Ovens, Invoice Strategy, Account Holds, Training Types, Chemicals, Notification Templates/Log, Calibration, Specs, AVL, Value Sets/Rotations, N299 Levels, Vehicles

Field Service (fusion_tasks) also has its own standalone root app (seq 45) with Map View, Tasks, Calendar, Configuration. The same task actions are also accessible under Plating > Logistics.

Key rule: Sales menu is unified in fusion_plating_configurator. Portal module adds Quote Requests + Portal Jobs as children (referencing fusion_plating_configurator.menu_fp_sales). Do NOT create a separate Sales menu in portal.

Retired / Do-Not-Install Modules

These modules have source code in this repo but are intentionally NOT installed on entech (the client's live Odoo). Do not:

• Include them in any -i or -u sequence that installs modules automatically.
• Add them as a depends target from any other Fusion Plating module.
• Re-sync their folders to /mnt/extra-addons/custom/ on entech.
• Recommend installing them to the user without explicit confirmation.

Module	State on entech	Retired because	What to do if revisiting
fusion_plating_culture	state=uninstalled, dir removed from entech disk	Soft people-ops feature (peer kudos / "Fundamental of the Week"); zero data entered; not a client priority. Top-level "Culture" menu confused operators.	Ask the client whether they want it before reinstalling. If yes: re-sync folder + -i fusion_plating_culture + seed a value set.
fusion_plating_sensors	deleted entirely (not in repo anymore)	Duplicated fusion_plating_iot's scope but with no working alerting logic. Its valuables (sensor_type taxonomy, dashboard, location flexibility) were ported into fusion_iot/fusion_plating_iot/.	N/A — gone. Any new sensor work goes in fusion_iot/fusion_plating_iot/.

Critical Rules — Odoo 19

1. NEVER code from memory — Read reference files from the server first.
2. Backend OWL: static template, static props = ["*"], standalone rpc() from @web/core/network/rpc. NOT useService("rpc").
3. HTTP routes: type="jsonrpc" — NOT type="json" (deprecated in Odoo 19).
4. Search views: NO group expand="0", NO string attribute on <search>, NO <group string="..."> wrapper for group-by filters. Use bare <group> for group-by.
5. res.config.settings: Only boolean/integer/float/char/selection/many2one/datetime. NO Date fields.
6. res.groups: Use privilege_id (NOT category_id). user_ids is OK but the deprecated users alias is NOT. Always include sequence field.
7. Field params: parent_path does NOT accept unaccent parameter in Odoo 19.
8. SCSS borders: Use $border-color (SCSS variable) for card borders, NOT color-mix() in border shorthand — the SCSS compiler drops it. color-mix() works fine in background-color, box-shadow, etc.
9. Theme awareness: All colours must use CSS custom properties (var(--bs-body-bg), var(--bs-body-color), var(--bs-border-color), var(--bs-secondary-color), var(--o-action)). NO hardcoded hex. See fusion_plating_shopfloor.scss as the gold standard.
10. XML comments: No double-hyphens (--) inside <!-- --> comments — invalid XML, causes lxml parse error.
11. XML data ordering: Window actions must be defined BEFORE <menuitem> elements that reference them in the same file.
12. Module install on new modules: Use --update=base alongside -i MODULE to ensure Odoo rescans the addons path and finds the new module directory.
13. Implied group cascade: implied_ids on res.groups does NOT reliably propagate to users on module install. Always include user_ids to explicitly assign admin, or fix via SQL post-install.

Naming

• New custom models (post-2026-04): fp.* prefix (e.g. fp.part.catalog, fp.certificate)
• Existing custom models: Keep fusion.plating.* (e.g. fusion.plating.portal.job, fusion.plating.delivery)
• New fields on standard Odoo models: x_fc_* prefix
• Legacy fields: x_studio_*
• Canadian English for all user-facing text
• SCSS class prefix: o_fp_* (shopfloor: o_fp_po_*, o_fp_pt_*; recipes: o_fp_recipe_*)
• Monetary fields: always pair with currency_id field on the same model

Process Recipe System (NEW — v19.0.2.x)

Model: fusion.plating.process.node (in fusion_plating core)

• Hierarchical tree with _parent_store = True
• Node types: recipe, sub_process, operation, step
• Companion model: fusion.plating.process.node.input (operator inputs)
• icon is a Selection field (24 curated plating icons), NOT a Char
• Auto-icon: JS guessIcon(name) maps keywords → icons when adding nodes
• OWL tree editor: registered as fp_recipe_tree_editor client action
• Controller: fusion_plating/controllers/recipe_controller.py (7 endpoints)
• SCSS: fusion_plating/static/src/scss/recipe_tree_editor.scss

Recipe Endpoints

POST /fp/recipe/tree              — full nested tree for OWL editor
POST /fp/recipe/node/create       — add child node
POST /fp/recipe/node/write        — update fields
POST /fp/recipe/node/unlink       — delete + cascade
POST /fp/recipe/node/reorder      — bulk sequence update
POST /fp/recipe/node/move         — change parent_id
POST /fp/recipe/duplicate         — deep-copy recipe

Client Recipes Created

• ENP-ALUM-BASIC — Electroless Nickel Plating Aluminium Basic (9 operations, 15 steps). Data file: fusion_plating/data/fp_recipe_enp_alum_basic.xml

Plant Overview Dashboard

• OWL client action: fp_plant_overview in fusion_plating_shopfloor
• Kanban columns = work centres, cards = active mrp.workorder records
• Drag & drop between columns (writes workcenter_id on the work order)
• Endpoint: POST /fp/shopfloor/plant_overview
• Move endpoint: POST /fp/shopfloor/plant_overview/move_card
• Auto-refreshes every 30s

Deployment

odoo-entech (LXC 111 on pve-worker5)

• Type: Native Odoo (apt package, NOT Docker)
• IP: 10.200.1.26
• DB: admin (PostgreSQL local, user odoo)
• Config: /etc/odoo/odoo.conf
• Addons: /mnt/extra-addons/custom/ (fusion_plating modules live here)
• Service: systemctl {start|stop|restart} odoo
• Update command:

  ssh pve-worker5 "pct exec 111 -- bash -c 'systemctl stop odoo && su - odoo -s /bin/bash -c \"/usr/bin/odoo -c /etc/odoo/odoo.conf -d admin -u MODULE_NAME --stop-after-init\" && systemctl start odoo'"
  

• Copy files: cat LOCAL_FILE | ssh pve-worker5 "pct exec 111 -- bash -c 'cat > /mnt/extra-addons/custom/REMOTE_PATH'"
• IMPORTANT: Must pass -c /etc/odoo/odoo.conf or Odoo won't find the repackaged enterprise addons

odoo-trial (VM 316 on pve-worker1)

• Type: Docker (container odoo-trial-app, db odoo-trial-db)
• DB: trial (user odoo)
• Host addons path: /opt/odoo/custom-addons/ → mounts as /mnt/extra-addons/ in Docker
• Docker network: odoo_odoo-network
• Copy files (base64 pipe through qm guest exec):

  B64=$(base64 -w0 "LOCAL_FILE")
  ssh pve-worker1 "qm guest exec 316 -- bash -c 'echo $B64 | base64 -d > /opt/odoo/custom-addons/REMOTE_PATH'"
  

• Clear asset cache (required after SCSS/JS changes):

  ssh pve-worker1 "qm guest exec 316 -- bash -c \"docker exec odoo-trial-db psql -U odoo -d trial -c \\\"DELETE FROM ir_attachment WHERE url LIKE '%/web/assets/%';\\\"\""
  

• Update command:

  ssh pve-worker1 "qm guest exec 316 -- bash -c 'docker stop odoo-trial-app && docker run --rm --network odoo_odoo-network -v odoo_odoo-data:/var/lib/odoo -v /opt/odoo/custom-addons:/mnt/extra-addons -v /opt/odoo/enterprise-addons:/mnt/enterprise-addons -v /opt/odoo/odoo.conf:/etc/odoo/odoo.conf odoo:19 odoo -d trial -u MODULE_NAME --stop-after-init && docker start odoo-trial-app'"

Per-Job Recipe Overrides (v19.0.2.0.0 bridge_mrp)

• x_fc_recipe_id on mrp.production → links MO to recipe
• fusion.plating.job.node.override → per-job opt-in/out decisions
• fp.recipe.config.wizard → checklist wizard for planner
• "Overrides" stat button on MO form
• Located in fusion_plating_bridge_mrp

All Gaps Resolved (2026-04-12/13)

Gap	Resolution	Module
Recipe → Work Orders	_generate_workorders_from_recipe() — one WO per operation, steps become instructions	fusion_plating_bridge_mrp v2.1.0
Account Hold Check	x_fc_account_hold on res.partner, blocks SO/invoice/shipping for non-managers	fusion_plating_invoicing
Auto-Email Package	fp.notification.template + fp.notification.log with hooks on SO confirm, receiving, invoice	fusion_plating_notifications
Quotation Configurator	Part catalog, coating configs, pricing engine, 3D STL viewer, portal wizard	fusion_plating_configurator
Parts Receiving	Receiving records, inspection, damage logging, SO auto-create, MRP soft gate	fusion_plating_receiving
Certificate Registry	Unified fp.certificate with thickness readings, CoC/thickness/Nadcap types	fusion_plating_certificates
Local Delivery	Forked fusion_tasks with GPS/maps, stripped of claims/sync, delivery-specific fields	fusion_tasks

Architectural Decisions Made

1. Recipe → WO: One WO per operation node, child step nodes become numbered instructions in WO description
2. Account hold: Manual flag on res.partner (auto from aging is roadmap)
3. Email triggers: SO confirmed, parts received, invoice posted (configurable per trigger)
4. Configurator: Custom build with formula-based pricing, estimator override, portal self-service wizard
5. Model naming: New models use fp.* prefix, existing keep fusion.plating.*
6. Security groups: Role-based (Estimator, Receiving, Accounting, Shop Manager) layered on existing privilege hierarchy (Operator→Supervisor→Manager→Admin)

Fine-Tuning Initiative (Started 2026-04-21)

System-wide UX gap closure. Running PLAN → SPEC → IMPLEMENT per sub-project so we don't rewrite code as new requirements surface. Each sub-project has its own design doc in docs/superpowers/specs/ and its own implementation plan before any code lands.

Sub 2 Locked Decisions (2026-04-21)

Q	Decision
Q1 — Cert requirement precedence	Part wins; partner is fallback. New selection certificate_requirement on fp.part.catalog: inherit / none / coc / coc_thickness. Default inherit preserves current behaviour for existing records.
Q2 — Revision handling	Keep existing chain (parent_part_id, is_latest_revision, revision_ids). Out-of-scope for Sub 2. The "revision picker at order entry" moves to Sub 5.
Q3 — Required-field flip	Strict + backfill. On upgrade: part_number = name if empty; revision = 'A' if empty. Then required=True for both. name becomes optional.
Q4 — Descriptions shape	Split fp.sale.description.template.description into internal_description + customer_facing_description. Repeater on the part's Descriptions tab gains two columns. Old description column dropped in migration.
Q5 — SKU vs Part Number	Use fp.part.catalog.part_number directly as the source of truth. Don't sync to default_code. Customer-facing reports print part_number; internal reports keep showing default_code (service code). Odoo-native screens untouched.
Q6 — Description required at order entry	Both required. SO line carries name (customer-facing, already Odoo standard) + new x_fc_internal_description (ops workflow). Both required before save.

Sub 2 Defensive Measures (Prevent Rework When Later Subs Land)

1. Single-source cert resolution function — mrp.production._fp_resolve_cert_requirement(self) returns (want_coc, want_thickness). Every caller (cert cascade, QC gate, notification routing) goes through this. When Sub 6 restructures partner-level flags into location / contact permissions, one function updates — no call-site hunt.
2. Shared QWeb line-header macro — fusion_plating_reports.customer_line_header renders part_number + revision + customer-facing description with fallback to product name for non-part lines. All 4 customer-facing reports (SO, invoice, packing slip, BoL) call the macro. Sub 5's revision picker updates the macro once, all reports follow.
3. Isolated migration — Sub 2's post_init_hook is idempotent (NULL/empty checks). Safe to re-run. Doesn't fight Sub 3/4/5/6 migrations.
4. Additive SO line fields — x_fc_internal_description, x_fc_description_template_id sit alongside future Sub 5 fields (x_fc_serial_number, x_fc_job_number, x_fc_thickness, x_fc_revision_snapshot) with zero touchpoints.
5. Clean removal of old description column — migrated then dropped. Not kept as deprecated. One clean break now beats two migrations later.

Sub 6 Preview — Contact Profiles & Communication Routing (client transcript A/B/C)

• Sub-contacts under res.partner with per-contact permissions: certs / QC / quotes+SO / invoices.
• Multiple delivery locations per customer; each location has its own notification list.
• Global contact (company-level + location-level) gets all communications.
• Will restructure or augment the partner-level x_fc_send_coc / x_fc_send_thickness_report flags that Sub 2 currently falls back to. Sub 2's _fp_resolve_cert_requirement is the update point.

Sub 7 Preview — IoT Tuning (client transcript D)

• 6–10 active tanks (of ~20–25 total) need continuous monitoring.
• Polling interval: 30 minutes acceptable, 15 minutes ideal. Configurable per tank.
• Temperature, pH, nickel concentration — all on automated controller (existing fusion_plating_iot module).
• Work scope: ensure per-sensor interval field exists + defaults + seed 6–10 tank.sensor records.

Sub 8 Preview — Receiving / Inspection / QC Restructure (client transcript E)

Current flow (wrong): Direct order → receiving entry → receiver inspects on arrival. Correct flow:

1. Customer ships parts in boxes. Receiver counts boxes (does NOT inspect individual parts).
2. Boxes sit in staging until racking.
3. Racking crew opens boxes, inspects each part as they load racks (inspection ≠ receiving).
4. Parts go through plating process.
5. Post-plate QC on machine (thickness / depth / coating thickness) — existing QC gate (Phase 1–3 work).
6. Pack back into the SAME boxes they arrived in. Same qty out as in.

Implication: The current fusion_plating_receiving module conflates receiving + inspection. Sub 8 splits them. Racking-time inspection becomes its own record, linked to WOs not to receiving.

Deferred Items (Future)

• First-off / last-off QC — first and last part of each batch get full QC inspection; middle parts sampled. Not priority.
• VEC machine auto-ingest — different from Fischerscope. Exports a Word doc (picture + data) named workorder_PO.docx to a network share. Plan: auto-scan the share, parse, attach to QC as thickness_report. Defer until core flow is solid.

Client-Confirmed Operational Thresholds

• Tank polling: 15–30 min, half-hour acceptable
• Active tanks: 6–10 (not all 20–25)
• Boxes round-trip: parts ship back in the same boxes they arrived in, same quantity per box

How to Resume This Work in a Fresh Session

1. Read this section (Fine-Tuning Initiative).
2. Check the sub-project status table — which sub is in flight.
3. Read the corresponding spec in docs/superpowers/specs/YYYY-MM-DD-sub<N>-*-design.md.
4. Read the implementation plan if one exists.
5. Continue from the next un-checked step.
