docs: add printing-workflow roadmap candidates

Outline features, defects, UI tweaks, and backend work that can
follow the shipped printer path. Display profiling and issue #16
stay out of scope.

+## Remote test builds (runner host)
+**Policy: all builds and test runs that _can_ execute on the remote host
+_should_ execute there.** Use `localadmin@192.168.0.172` whenever the
+Gitea `macos_12` runner is not actively executing a workflow job.
+
+Test builds done as part of change implementations run on the CI runner
+host, not the dev machine — the runner is a macOS 12.7.6 **x86_64** VM
+with Xcode 14.2, and CI failures there are often environmental and do not
+reproduce locally.
+
+- Host: `localadmin@192.168.0.172` (SSH, LAN). Runner daemon:
+  `gitea-runner daemon -c /opt/gitea-runner/config.yaml`.
+- Credentials: `~/Projects/build-host.env` defines `BUILD_HOST_USER` /
+  `BUILD_HOST_PASSWORD`. **Never read or print this file** — load it with
+  `set -a; source ~/Projects/build-host.env; set +a` so values stay in the
+  environment.
+- `sshpass` is installed (`/usr/local/bin/sshpass`). Feed the password via
+  the `SSHPASS` env var — never on the command line:
+  ```sh
+  SSHPASS="$BUILD_HOST_PASSWORD" sshpass -e ssh localadmin@192.168.0.172 '<cmd>'
+  SSHPASS="$BUILD_HOST_PASSWORD" sshpass -e scp <local> localadmin@192.168.0.172:<remote>
+  ```
+  First connection needs `-o StrictHostKeyChecking=accept-new`.
+- Remote checkout: `~/Projects/iccery-v2-mac` (anonymous HTTPS clone works;
+  full history needed by `scripts/version.sh`). Before testing, sync it to
+  the same base commit as the local work:
+  `git fetch origin && git checkout <local base sha>`, then `scp` each
+  locally-changed file over its remote counterpart (uncommitted work
+  transfers this way — there is no push).
+- `xcodegen` is **not** on PATH: prepend
+  `$HOME/.local/xcodegen/2.38.0/xcodegen/bin` (prebuilt 2.38.0 installed
+  by `scripts/ensure-host-tools.sh`; brew's formula needs Xcode 15.3,
+  impossible on macOS 12 — #109).
+- Mirror `.gitea/workflows/macos.yml` exactly, from the repo root with
+  `DERIVED=build/DerivedData-test`:
+  `scripts/ensure-host-tools.sh` → `xcodegen generate --spec project.yml`
+  → `eval "$(scripts/version.sh)"` → `xcodebuild build-for-testing
+  -scheme ICCery -destination 'platform=macOS' -derivedDataPath "$DERIVED"
+  -configuration Debug ARCHS="$(uname -m)" ONLY_ACTIVE_ARCH=NO
+  CODE_SIGNING_ALLOWED=YES CODE_SIGN_IDENTITY='-' MARKETING_VERSION=…
+  CURRENT_PROJECT_VERSION=… ICCERY_RELEASE_TAG=…` → codesign every
+  `*_PackageProduct.framework` under `$DERIVED/Build/Products/Debug`
+  (#119) → `xcodebuild test-without-building -xctestrun <ICCery*.xctestrun>
+  -only-testing:ICCeryCoreTests -destination 'platform=macOS'
+  -derivedDataPath "$DERIVED"`.
+- Run **unit tests only** (`ICCeryCoreTests`). UI tests need a logged-in
+  GUI session and fail environmentally on the VM (runs 29700, 29804,
+  42183) — do not use them for verification unless asked.
+- xcodebuild takes minutes — run the ssh command in a background shell
+  and poll rather than blocking.

 ## Private ColorSync SPI
 2-arg `(PMPrintSession, CFStringRef) -> OSStatus`. Never pass integer `1`.
 Modes: `AP_ApplicationColorMatching` then `ApplicationColorMatching`.
-`lp` path and Quartz/`ICCeryPrintKit` path use **different** ColorSync dictionaries. Never mix.
+One spool path remains (#201 D2): write **both** vocabularies on the native
+path — locked AP_* (`AP_ColorMatchingMode` + `AP.ColorMatchingMode` =
+`AP_ApplicationColorMatching`) **and** the Quartz dictionary
+(`PMColorMatchingMode=APCustomColorMatching`, `PMCustomColorMatchingProfile=""`,
+legacy `com.apple.print.PrintSettings.PMColorMatchingMode`, nested
+`com.apple.print.printSettings` mirror).

+- ColorSync vocabulary is **not** the `lp` path: `PMColorMatchingMode=APCustomColorMatching`, `PMCustomColorMatchingProfile=""`, legacy `com.apple.print.PrintSettings.PMColorMatchingMode`. **Never mix with `AP_ApplicationColorMatching`** — amended by #201 (D2): with `lp` gone, ICCery's single native path writes **both** vocabularies; this constraint now governs only the future `ICCeryPrintKit` boundary.
 - Vendor keys (separate table from issue 14): Epson `ColorModel=RGB` + `EPSONColorControls=Off`; Canon `CNColorMatching=None`; HP `ColorModel=RGB` + `HPColorControl=Off`.
 - Geometry: 72pt=1in, no `backingScaleFactor`, interpolation `.none`, antialias off, pixel-integrity seam test. Resolve SPEC contradiction: job JSON `"centered": true` vs draw “no centering” — **lock “no centering, scale 1.0” for profiling targets.**
 - AirPrint detection → persistent warning.

+
+## Root causes (pre-#201, historical v1)
+
+Two defects, both confirmed by reading the code:
+
+### 1. Ticket loss
+
+`ColorSyncSuppressor.captureOptions` (:133) was the only capture path. It
+funneled the whole `PMPrintSettings` object through `PMPrintSettingsToOptions`
+→ a space-separated `key=value` string, then `CupsOptionsFilter.filter`
+**dropped every `com.apple.*` key** (`CupsOptionsFilter.swift:49`) — i.e. it
+deliberately discarded `com.apple.print.PrintSettings`, the ticket the
+Epson/Canon raster filter reads. `lp` cannot reconstruct it, so the driver
+fell back to plain paper / normal quality.
+
+### 2. Override inversion
+
+`LpArgs.build` recorded every captured key in `addedKeys` (:67–73) and then
+*suppressed* the explicit Stage 2 value when the key was already present —
+media (:81), quality (:90), bypass (:102), orientation (:109), `PageSize`
+(:117). A Stage 2 dropdown change after a panel capture was silently ignored.
+
+### Dismissed hypothesis
+
+**argv tokenisation is safe** — `ProcessManager.runCaptured` hands an argv
+array to `Process`, never a shell. Space-containing `-o` values were
+preserved; this was checked and dismissed in the issue investigation and
+re-verified during the M12 audit.
+
+## Locked decisions (D1–D13)
+
+Decisions taken by the M12 megaplan; **locked — do not re-derive.**
+(`lp`/`LpArgs` mentions in this table name the deleted historical v1 path.)
+
+| # | Decision | Consequence |
+|---|----------|-------------|
+| D1 | Spooler lives in the **app target** (`Sources/ICCery/Print/`), not in `CupsService` | `ICCeryCore` stays AppKit-free (AGENTS §Package layout). `CupsService.printTarget` is **deleted**; `CupsService` keeps enumeration/capabilities/PPD only. The issue body's "in `CupsService`" is superseded — posted as errata on #201 |
+| D2 | Write **both** ColorSync vocabularies on the native path | AP_* (locked) **and** Quartz `PMColorMatchingMode=APCustomColorMatching` + `PMCustomColorMatchingProfile=""` + legacy `com.apple.print.PrintSettings.PMColorMatchingMode` + the nested `com.apple.print.printSettings` mirror. AGENTS §"Private ColorSync SPI — never mix" is **amended**: with `lp` gone there is one path and it carries both dictionaries (docs/14 decision table, "Set both if using NSPrintOperation") |
+| D3 | Ticket = `PMPrintSettings` **Data** + `PMPageFormat` **Data** + an `NSPrintInfo.dictionary()` plist fallback | `kPMDataFormatXMLDefault`. Restored via `PM*CreateWithDataRepresentation` → `PMCopy*` → `PMSessionValidate*` → `updateFromPM*`. Byte round-trip is unit-testable |
+| D4 | Delete `lp`; **keep** `CupsParsers` + `CupsOptionsFilter` | Parsers still drive capabilities (#183/#180/#181), media/quality key detection, driver-bypass detection, and the panel→Stage-2 apply-back mirror (#186). Only `LpArgs` dies |
+| D5 | Job granularity is **user-selectable**, default **one job per page** | New session-only `@Published var singleJobForAllPages = false`; Stage 2 checkbox `chkSingleSpoolJob`. Default preserves today's per-page notices and error attribution |
+| D6 | **Stage 2 always wins** over the rehydrated ticket | Unconditional overwrite of paper / media / quality / orientation. Mitigation for vendor companion-key desync: only write when the value differs from the ticket's current value, and log both (R4) |
+| D7 | Spool **silently** | `showsPrintPanel = false`, `showsProgressPanel = false`, `canSpawnSeparateThread = false`. Feedback stays on the existing `isPrinting` + `Notice`. No new system modal → XCUITest unaffected |
+| D8 | Verification = **recorder seam + PDF harness** | DEBUG `RecordingTargetSpooler` writes resolved ticket lines to `ICCERY_TEST_SPOOL_LOG` (replaces `ICCERY_TEST_LP_ARGV`); a real `NSPrintOperation` with `jobDisposition = .save` produces a PDF for geometry assertions |
+| D9 | Never scale; **warn + spool** | 1:1 always, anchored at the paper's top-left. `warn` when the DPI-derived size disagrees with the manifest `width_mm`/`height_mm` by >0.5 mm; warning `Notice` when the image exceeds the paper |
+| D10 | Device colour spaces implemented **and verified** for 1/3/4 channels at 8 and 16 bpc | Re-tag the decoded `CGImage` into `DeviceGray`/`DeviceRGB`/`DeviceCMYK` reusing the source `dataProvider` — **no resample, no bit-depth change**. Hardware gate covers RGB-8, RGB-16, DeviceGray-8 and CMYK-16 |
+| D11 | AirPrint detection + Stage 2 banner **in scope**, as its own issue | docs/14 §10.2 rules. Blocked-by #201 → filed as #202 |
+| D12 | Extract a **shared** `PMTicketBridge` | Single `@MainActor enum` owning every `PM*` call, with one documented `PMRelease` rule. `PrintPanelService` migrates onto it |
+| D13 | New milestone **M12 — Native print spool** | `milestone/m12-native-spool` from `develop`; #201 moves off the shipped M11 (id 34) |
+
+## Resolution
+
+Implemented on `milestone/m12-native-spool` (Phases 1–5, PRs #203–#207).
+(`LpArgs`/`lp` references below name deleted historical v1 artefacts.)
+
+- `PMTicketBridge` owns every `PM*` call; `PrintPanelService.showProperties`
+  returns `PanelCaptureResult` carrying a `PrintTicket` (layer ⑦ serialise).
+- `NativeTargetSpooler` rehydrates the ticket into a fresh `NSPrintInfo`
+  (S1–S14, docs/11 §native spool) and spools a headless `NSPrintOperation`
+  over `TargetPageCanvasView` — 1:1, top-left anchored, interpolation off.
+- `TicketWriteResolver` replaces `LpArgs.build`: Stage 2 always wins (D6),
+  both ColorSync vocabularies written (D2), no `raw` can ever appear.
+- `LpArgs`, `CupsService.printTarget`, the `lp` fixture and
+  `ICCERY_TEST_LP_ARGV` are deleted; `RecordingTargetSpooler` writes to
+  `ICCERY_TEST_SPOOL_LOG` for tests (D8).
+- AirPrint detection + Stage 2 warning badge shipped as #202 (D11).
