Conversation
… behavior Window load recovery destroyed the last window before its replacement existed, so the Windows/Linux all-closed listener quit the app mid-recovery; the guard now lives in a testable module and is set before the destroy. Holds lost the cashier's waived and opted-in charge decisions: two additive held_orders columns, validated bounded-id API fields, store/cart restoration, and POS/Orders resume wiring carry them through hold and reload. Menus advertised an unsellable parent price while selling variants, on both the thermal document and the paper/PDF HTML, so active variants now expand into their own sale rows with POS stock and recipe-link semantics. Remote updates and backup polling refreshed only page one, leaving loaded history stale; both triggers now refresh every loaded page. A configured collection method named Pending or Unknown collided with the builtin sentinels. Orders store an additive, non-FK identity column beside the existing name snapshot, and the delivery slip prints a configured method's stored name literally while sentinels stay localized.

- Around line 281-283: Update the payment-method selector in CartPanel to render
the cart’s stored method name as a fallback option when its custom method ID is
absent from the loaded options. In the selector’s change handler, preserve the
cart value when that fallback is selected instead of storing the custom ID token
as the method name.

Intent
USER GOAL (verbatim work order): Fix the remaining post-3.12 FloCafe regressions - a bounded enhancement comprising surgical bug fixes plus additive held-cart and custom-expected-collection-method migrations. Restore reliable window load recovery, cashier charge decisions across hold/restore, variant menu prices, live history updates, a deterministic permission regression test, and unambiguous delivery collection choices, while preserving existing POS, authorization, printing, regional, and inventory contracts.
REVIEW ITEMS AND WHAT THIS COMMIT DOES
Last-window destruction shut down load recovery on Windows/Linux (main/index.ts recoverFailedWindow). Fixed: the all-closed quit guard now lives in a testable main/window-recovery.ts module, is set before the destroy, and is restored in finally including create failure. Rationale for extracting a module instead of an inline guard: the task's checkpoint suites run under ELECTRON_RUN_AS_NODE, where Electron app/BrowserWindow do not exist, so the four required scenarios (create success, create failure/relaunch, already-destroyed input, normal quit outside recovery) are only reachable through a main-process module - matching this repo's existing window-readiness.ts / window-load-retry.ts pattern - rather than by duplicating the function. It also removes the identical flag dance the renderer-crash path already carried.
Hold/restore lost waived and opted-in charges. Fixed end to end: additive migration v105 adds held_orders.waived_charge_ids and held_orders.opted_in_charge_ids (TEXT NOT NULL DEFAULT '[]'); the held-orders route validates and round-trips bounded charge ids (CHARGE_ID_PATTERN, MAX_CHARGE_ID_LENGTH, MAX_CHARGE_DEFINITIONS from shared/charges.ts), deduplicates, rejects malformed input with 400 while leaving the stored hold untouched, degrades malformed persisted selection JSON to empty without dropping the cart, and preserves unknown-but-well-formed ids because the charges engine remains authoritative about applicability at order creation. Frontend held-order store, cart loadItems (independent Sets, never aliased arrays), and the POS CartPanel / POS page / Orders resume callers pass the arrays through. Backend authority over prices and tax is unchanged; persisted ids are choices, never trusted amounts.
Electron menu fallback receiving an explicit null was already addressed by PR fix: improve POS, inventory, and printing workflows #984 (the modal passes undefined in Electron). Verify-only item; deliberately NOT changed here.
Menus printed an unsellable parent price instead of variants, in both the thermal document route and the browser paper/PDF HTML. Fixed in both: active variants expand into one existing menu row per variant, in catalog order, named "Parent (Variant)" at the variant's own price; a product with no active variants keeps its single parent row; inactive variants are excluded; a recipe-linked variant is not gated by its own pool; includeOutOfStock decides whether a sold-out variant row is emitted; the emitted item count counts rows on every destination (thermal, paper, PDF). No new UI toggle, translation key, destination, or page layout was added.
Remote updates left loaded history stale: both the KDS WebSocket handler and the 10s backup-polling interval now pass refreshLoadedPages: true, reusing the existing fetchLoadedOrderPages helper and keeping the one-second coalescing, in-flight protection, search invalidation, cursor bookkeeping, and local-action behavior. A failed older-page request rejects before setOrders, so the previous visible snapshot is retained rather than merged from a partial failure.
Charge-permission E2E test counted two Orders mounts against one mount's budget. Fixed by deleting the redundant post-login navigation and waiting for the Orders page that sign-in already lands on, scoping the settings-read budget to that single mount. The maximum of two reads and every permission, read-only charge UI, and cleanup assertion are unchanged. No production permission or authorization code was touched.
Approved additive P3 item: custom collection methods named "Pending" or "Unknown" collided with the builtin sentinels. Migration v106 adds nullable orders.expected_payment_method_id - a historical identity marker that is deliberately NOT a foreign key - while preserving the existing expected_payment_method name snapshot; old rows get null ids and the old "pending" string is never guessed into a custom identity. Order-create accepts an optional expected_payment_method_id: a present id must be a positive safe integer naming an ACTIVE configured method, the server stores that method's canonical name plus the id, a supplied nonempty name must match it case-insensitively or the request is 400, an absent or null id keeps the exact legacy string/sentinel contract, and non-delivery orders persist both expected-method fields as null. The cart holds expectedPaymentMethodId alongside its existing string; built-in/sentinel selection clears it; custom dropdown options use distinct custom: values resolved from the loaded methods; the id is included in both order POST bodies and the prepaid retry fingerprint. DeliverySlipPrintData.payment gained optional expectedMethodIsCustom; the backend builder derives it from the persisted id (so a later rename or deactivation cannot rewrite history) and the semantic thermal, WebUSB, and browser slip renderers propagate it, printing a configured method's stored name literally while builtin/sentinel words stay localized. Actual payment settlement, balances, and the payment picker are untouched; fully paid/refunded slip behavior is still governed by real bill payments.
VERIFICATION RUN AND PASSING IN THIS SESSION (all exit 0): npm run lint, npm run build, npm run build:frontend, npm run test:script-coverage, npm run test:held-orders, npm run test:cart-variant-identity, npm run test:charges, npm run test:charges-engine, npm run test:product-variants-orders, npm run test:menu-printing, npm run test:print-menu-printer-selection, npm run test:receipt-column-oracle, npm run test:orders-search, npm run test:orders-layout-settings, npm run test:delivery-address, npm run test:delivery-slip, npm run test:integration-payments, npm run test:shutdown-lifecycle (now including the new failed-window recovery lifecycle phase), npm run test:window-load-retry, npm run test:upgrade-path, npm run test:migration-registry (v1..v106), npm run audit:db, npm run docs:check, and git diff --check.
RED-GREEN EVIDENCE: with the recovery guard's flag assignment removed, the new lifecycle phase fails on "destroying the failed window during recovery must not quit the app"; with migration v105's column adds removed, the upgrade fixture fails on the fresh-schema held_orders columns; with the held-orders route's selection serialization emptied, the hold/fetch round-trip case fails. Reverting each fix restores its failure.
DELIBERATELY NOT DONE IN THIS COMMIT (deferred, not overlooked): the new or extended Playwright specs for the hold-resume flow, the paper/PDF menu variant rows and printer-fallback proof, the remote-history-refresh regression, and the custom-method UI/retry proof were not authored, so browser-level acceptance for items 2, 4, 5 and 7 rests on route, store, and document-level tests only. The full npm test suite and the full Playwright browser suite were not re-run in this session because they exceed the session's tool budget, so cross-platform native Windows/Linux recovery and signed packaging remain unverified. Item 6's fix is source-only until its spec is run.
What Changed
Risk Assessment
Testing
Drove the held-cart, menu printing, live history, custom collection method, permission, and window recovery flows against isolated running services and Electron, then ran focused API, migration, printing, and lifecycle checks. The supplied verification run was used as baseline; the full repository and Playwright suites were not rerun. Initial temporary-driver setup gaps (missing language seed and empty native catalog) were corrected and the affected flows rerun. Visual evidence covers the changed UI and print surfaces; the permission regression was verified through live UI assertions. Native Windows runtime behavior remains unverified. Both temporary drivers and generated test results were removed, leaving the worktree clean.
