Saved theme and backgrounds resolve after package relocation

Physical board, 2026-09-27 UTC. Candidate source 433a4226, system /nix/store/11y992kp7bikr5hg21i2azfvmca43i7i-nixos-system-nixos-26.11.20260919.20b1ddd. Both booted and running system identities matched the candidate during this one-time boot. The exact kernel and service executables are in result.json.

Before the repair, the catalog returned a null active ID and the background row stayed loading; see the browsing observation. With the repair, k230-theme list returns an active ID, 23 catalog entries and the preserved generation. Its saved report contains five backgrounds. The native image shows the saved theme centered, marked “Current theme,” and its background row populated with “Current background” on the saved selection. The generation identity hash exactly matches the earlier runs; no theme was activated and no saved pointer was rewritten.

Reproduction and limits

After verifying the candidate’s system and service identities, show Settings as the shell user:

runuser -u shell -- env XDG_RUNTIME_DIR=/run/shell k230-shell-rust --surface settings

The coordinator injected one tap at (480,130) through the distinct virtual touchscreen, using native_touch from the browsing collector. The fixture verifies its name and /sys/devices/virtual/input provenance; the physical touch device is never written. After the picker settled:

runuser -u shell -- env XDG_RUNTIME_DIR=/run/shell WAYLAND_DISPLAY=wayland-1 grim /run/shell/picker-fixed.png
runuser -u shell -- env XDG_RUNTIME_DIR=/run/shell k230-theme list

Raw list output remained private; the committed result retains only counts, booleans, a generation identity hash and approved runtime identities.

The original one-shot trial established selection lookup and populated content, but left normal installation and repeated browsing open. The following installed-system check closes those remaining task 12.2 gates.

Installed system and repeated browsing

The corrected persistent installation and normal reboot are verified in the combined install evidence. The installed 11y992kp… system resolves the same saved theme, 23 catalog entries and five backgrounds. Its initial native screenshot is byte-for-byte identical to current-theme.png above; see identities and hashes.

An injected horizontal background drag from (430,990) to (190,990) visibly moved the row from “On pole” to “Eyed,” displaying “Tap to apply.” The saved generation was not changed. The image was visually reviewed.

After returning to Settings, the same bounded browsing collector ran with --device /dev/input/event1 --expect-rust-exe <installed Rust path> --state-root <protected active-state root> --label new --output <unique private JSON> --settings-ready. The fixture identity was verified as virtual. It browsed six theme swipes, four background swipes, returned to Settings, reopened, and repeated six warm theme swipes, with two 15-second idle windows. No media capture ran during measurement. The native images were captured separately. The public result was reduced using the same allowlisted reducer; only its single-run comparison limit was clarified.

This completes task 12.2: installed content resolves and responds while browsing preserves the saved theme. It does not establish smooth swipes or an improvement over the earlier run, whose background content was missing. Task 11.3 and the matched profiling/optimization work in task group 13 remain open. Commit gaps are shell submission timing, not panel presentation FPS; all gestures here are injected, not real-finger acceptance.
