- Detect vendor tray keys in CupsParsers with InputSlot/MediaSource/EPIJ_FdSo/EPIJ_PSrc/CNIJMediaSupply roster; EPIJ_FdSo wins over EPIJ_PSrc.
- PrinterTray now carries raw token + display name; PrinterCapabilities exposes trayKey, trayDefault and tray-specific quality maps.
- CupsService enumerates trays from the detected key, enriches labels from PPD, seeds selection from CUPS default, and precomputes per-tray media→quality constraints.
- MediaQualityConstraints resolves quality availability from both selected media and selected tray, falling back to the media-only map.
- TicketWriteResolver emits the selected tray key=token in the locked write order between PageSize and media key.
- PrintPanelService applies the Stage 2 tray token to PMPrintSettings on open and captures the tray back from the full roster plus AP_D_InputSlot.
- PrintSessionViewModel keeps selectedTrayToken, applies capture-back, preserves unknown captured tokens as synthetic trays, and passes tray into spool overrides.
- Stage2View replaces portrait/landscape buttons with an orientation dropdown (printerOrientationSelect) while preserving portrait/landscape semantics and orientation-requested=3|4.
- Add/update core, UI and fixture tests for tray detection, enumeration, PPD labels, defaults, unknown-token synthesis, panel capture, ticket write order and tray-aware quality clamping.
- Update docs/10-print-system.md, docs/11-print-macos.md, docs/21-ui-reference.md and docs/24-issues-invariants.md.
Verified on the macOS 12.7.6 x86_64 CI runner: xcodebuild build-for-testing and ICCeryCoreTests pass (557 tests, 0 failures).
The bound NSPrintPanel always opened on queue driver defaults —
capturedTickets[queue] was stored but never passed back, so every
vendor-PDE setting outside the four mirrored fields was discarded
on reopen (RC1), and pre-selection writes were never validated into
the ticket before runModal (RC2).
Extract the pre-modal configuration into a testable
configureBoundPanel seam with the spooler's S4→S7 order: ticket
restore (warn-only, unlike the spooler's fatal try — a stale ticket
must not keep the dialog from opening → Stage 2 selections (D6
parity) → PMSessionValidatePrintSettings + updateFromPMPrintSettings
→ applyPaper → suppression ②–⑤.
ICCERY_DEBUG_PANEL_DUMP=1 logs the raw PMPrintSettingsToOptions
output and serialised ticket sizes pre/post modal for the XP-55
RC3 verification.
