milestone: desktop path Phases 1-5

Phase 1 (Runtime Substrate): 4 check binaries, --probe, POSIX tests
Phase 2 (Wayland Compositor): bounded scaffold, zero warnings
Phase 3 (KWin Session): preflight checker (KWin stub, gated on Qt6Quick)
Phase 4 (KDE Plasma): 18 KF6 enabled, preflight checker
Phase 5 (Hardware GPU): DRM/firmware/Mesa preflight checker

Build: zero warnings, all scripts syntax-clean. Oracle-verified.

+*Note: As of 2026-04-29, the bounded `redbear-full` QEMU greeter proof passes (`GREETER_HELLO=ok`, `GREETER_VALID=ok`). Most items below are satisfied by the active config; remaining items are "verify via build."*
 
 | Blocker | Source | Fix |
 |---------|--------|-----|
 | greeter init service stub in greeter-services.toml | `20_greeter.service cmd = "true"` | Use `redbear-full.toml` service definition (already correct there) |
-| compositor binary path mismatch | `COMPOSITOR_BIN_PATH = /usr/bin/redbear-greeter-compositor` but recipe installs to `/usr/share/` first then `/usr/bin/` | Verify binary at `/usr/bin/redbear-greeter-compositor` in image |
-| seatd not in image | seatd recipe may not have been cooked | Ensure `seatd` package is in config and cooked |
-| redbear-authd not in image | authd recipe may not have been cooked | Ensure `redbear-authd` package is in config and cooked |
-| redbear-sessiond not in image | sessiond recipe may not have been cooked | Ensure `redbear-sessiond` package is in config and cooked |
-| greeter user account missing | TOML `[users.greeter]` may not be applied | Verify greeter user uid=101 exists in /etc/passwd in image |
+| ~~compositor binary path mismatch~~ (resolved) | Recipe installs to both `/usr/bin/` and `/usr/share/redbear/greeter/`; greeterd checks both | No action needed |
+| seatd package in config | seatd = {} now present in redbear-full.toml packages section | Rebuild to include seatd in image |

 | compositor requires DRM but QEMU has none | `kwin_wayland_wrapper --drm` fails in VM | Use `--virtual` in VM; compositor script already handles this |
