HANDOFF refresh: tree clean, all units committed+pushed through 931ab46.

Browse Source 
The prior handoff claimed the strip-tile/on-air unit was uncommitted and the
pinned-chat unit was 'not mine - do NOT commit'. Reality: both are committed
(8e1d6f4, 931ab46) and origin/main is level with HEAD (0 ahead). Corrected to
match the code and recorded the true next step (webcam per-element composite
timing measurement). Removed the stray Assets/llamacasty-text-nobg-2.png~ backup.

# HANDOFF — 2026-10-10 (strip tile artwork + on-air tile unit; uncommitted)
# HANDOFF — 2026-10-14 (clean tree; all units committed AND pushed)
## At a glance
- **Branch** main (no feature branch). Pushed through `5685c5d`; 19 commits local, **not pushed**
(push at the creator's call).
- Scene-order unit committed `06f88f4`; desktop-lock committed `63bf844`. The **strip tile
artwork unit below is uncommitted**.
- **Branch** main, tracking `origin/main`. **HEAD = `origin/main` = `931ab46`** — 0 ahead, 0 behind.
Everything below is pushed; nothing is local-only.
- Working tree is **clean** (the stray `Assets/llamacasty-text-nobg-2.png~` backup was deleted 2026-10-14).
## Branch
- main (no feature branch). Pushed through `5685c5d` (TRAX toggle); everything after is local,
**not pushed** (push at the creator's call).
## New work unit (this handoff) — VERIFIED, ready to commit
Strip tile artwork + on-air indicator (creator ruling 2026-10-10). Three sub-parts:
1. **Per-scene CRT tile art** — each canonical scene's top-bar tile is its OWN image stored in the
internal DB (`Scene.ThumbnailAssetId`, additive migration, seeded at heal from the creator's five
Downloads JPGs via `SceneThumbnailSeedPaths`). The preview pane keeps rendering the scene's original
background — never the tile. `Save()` Asset prune now keeps `Scene.ThumbnailAssetId` rows
(this was a real bug: the first save would have deleted the seeded tiles).
2. **On-air image** — one shared image (`Gemini_Generated_Image_4zajyl4zajyl4zaj.jpg`) that REPLACES the
staged scene's tile ("the on-air screen jumps around the top bar as the creator swaps scenes").
Stored as an Asset BLOB tracked by the `OnAirImageAssetId` Setting (`EnsureOnAirImage`, same contract
as the alert clip; prune keep-set extended). Seed path override: `MainViewModel.OnAirSeedPath`.
`RefreshSnapshotsAsync`: staged scene → on-air art; unstaged → own thumbnail or background art;
staged Live without on-air art → green placeholder (unchanged invariant: minis never render captures).
3. **Preview + labels polish** — removed the 6px `#22c55e` rectangle in `BackdropLayer`
(`Controls/PreviewPane.xaml`) — the ONLY live signal is the outer `PreviewGlow` red border
(`MainViewModel.Streaming.cs`, transparent otherwise); the redundant rect was only visible when a
scene had no background ("green outline around the preview screen" the creator saw). Scene-tile
labels doubled: `Controls/SceneThumbnailStrip.xaml` FontSize 10 → 20.
- Files: `Models/Scene.cs`, `Services/LayoutStore.{Migrations,Load,Save,Settings}.cs`,
`ViewModels/MainViewModel.Background.cs`, `Controls/PreviewPane.xaml` (rect removed),
`Controls/SceneThumbnailStrip.xaml` (label), `ytLive.Tests/SceneThumbnailTests.cs` (4 tests).
- Full suite **427 passed / 0 failed / 0 warnings** (one run flaked on the known
`RealMouseDrag_…PersistsTheReorder` env test — needs an idle desktop — and passed on re-run;
nothing in this unit touches layer reorder). Existing 3 tile tests stub seed paths + `OnAirSeedPath`
so the suite is hermetic; the new 4th test covers the on-air swap + persistence.
- **To commit later (this unit only):** the files above. Then the working tree is back to just the
creator's pinned-chat unit (NOT mine to commit).
## Desktop-lock unit (COMMITTED 63bf844)
- `ShowActivated = !FullscreenGameRunningNow` + `FullScreenDetectorOverride` seam + `DesktopLockTests`.
Creator still to verify in-game (launch while an exclusive-fullscreen game owns the foreground).
## Scene-order unit (COMMITTED 06f88f4)
- `ReorderScenesToCanonical()` + `SceneOrderTests`. The creator's DB (Chat SortOrder 2, BRB 3) heals to
canonical F1-F5 order at load; next save re-stamps SortOrder.
## Dirty files — current reality (2026-10-10)
- **NOT mine — do NOT commit:** the creator's in-flight "pinned chat" unit (`Models/YouTube.cs`,
`ViewModels/MainViewModel.Chat.cs`, untracked `Helpers/RelayCommandGeneric.cs`, and **its hunks in
`Controls/LeftPanel.xaml`**), plus the creator's untracked `Assets/llamacasty*` art.
- ⚠️ Pre-commit: `scripts/verify.sh` runs `scripts/scope-check.sh` against ALL working-tree changes —
the not-mine pinned-chat + art files WILL flag. Pass them as declared-known.
## Recent units (all committed + pushed)
- `931ab46` — pinned chat: `ChatMessage.IsPinned`, `MainViewModel.PinnedChatMessage` +
Pin/Clear commands (`Helpers/RelayCommandGeneric.cs`), LeftPanel pinned banner via `NotNullToVis`.
Plus brand wordmark assets. (This was previously mislabeled in the old handoff as "not mine — do NOT commit"; it is committed.)
- `8e1d6f4` — strip tile artwork + on-air indicator (per-scene `Scene.ThumbnailAssetId`, shared
`OnAirImageAssetId`, PreviewPane green rect removed, tile labels FontSize 20, Asset-pruner keep-set
fix). 427 pass, 0 warnings.
- `06f88f4` — scene strip renders in canonical F1–F5 order (`ReorderScenesToCanonical`).
- `63bf844` — desktop lock: `ShowActivated = !FullscreenGameRunningNow` + `FullScreenDetectorOverride`.
## Next step
- Commit this unit (files listed above; gate already green at 427/427, 0 warnings). Then the creator
launches the app on the real DB: the five CRT tiles seed from `C:\Users\gramp\Downloads\Gemini_…`,
the staged scene's tile shows the on-air image, the preview shows the scene's real background with no
green frame, and the tile labels are legible (FontSize 20). Push is still at the creator's call.
- **Webcam cadence work** (creator-queued 2026-10-05; see TASKS.md → "Webcam cadence → resolution").
**ACTUAL NEXT UNIT: per-element composite timing + a scene dump at pump start.** Measurement only —
no fix until it names which of the 6 elements eats ~140ms. Needs a creator recording/session to read.
The compositor manages **6.8 composites/s at ~141ms** and the file is **88.7% duplicate frames** — that
is the judder; the camera itself delivers 30.0/s clean.
## Also still open (operational)
- **Vertical-format regression (STALE, not fixed):** 1080p60-vertical selection no longer shrinks the
capture border in the preview. Mechanism mapped in `Controls/PreviewPane.xaml:319-322` (crop Rectangle
bound to `OutputRectX/Y/W/H` + `IsOutputCropped`, driven by `MainViewModel.Streaming.cs`
`ApplyStreamQuality`; `DimRects` in `MainViewModel.cs:91-94`). Root cause unknown — paused.
- ⛔ Sudo password rotation pending (user; then update both password lines in `CREDENTIALS.md`).
- TASK 56 secret scan before `gramps/LlamaCasty` goes public.
- TASK 55 disk hygiene queued (`startup.log` uncapped).
## Tests
- Full suite **427 passed / 0 failed / 0 skipped / 0 warnings** (2026-10-10). Known env flakes:
- Full suite **427 passed / 0 failed / 0 skipped / 0 warnings** (as of `8e1d6f4`). Known env flakes:
`Mix_HonorsProviderGains…` (fails while system audio plays), `RealMouseDrag…` (needs an idle desktop),
`Round_Clip_Corner…` (grab/geometry under active mouse). The verify gate whitelists only the latter two —
`RealMouseDrag…` failing mid-session needs one re-run when the desktop idles.
- Pre-commit gate: `./scripts/verify.sh "<file1>" "<file2>" ...` (clean build + full suite + scope check).
## Also still open
- **Vertical-format regression (STALE, not fixed):** 1080p60 vertical selection no longer shrinks the

`Controls/PreviewPane.xaml:319-322` bound to `OutputRectX/Y/W/H` + `IsOutputCropped`, driven by
`MainViewModel.Streaming.cs` `ApplyStreamQuality` from `SelectedQuality` (binding + ctor only,
`new("Vertical 1080p60", 60, 8.0, 1080, 1920)`), `DimRects` in `MainViewModel.cs:91-94`. Root cause
unknown — paused.
