# HANDOFF — 2026-09-22 (TASK 42 top bar redesign implemented; commit + full-suite rerun owed)

## Branch / Commit State

`main` HEAD = **`bb5dcb4` — feat(stream): TASK 41 Test Stream mode …** (TASK 41 committed).
Pushed state at `197ee81`. **Working tree DIRTY — TASK 42 implementation done, not yet committed**
(docs updated in this same pass; next step is scope-check + build + full tests + one commit):

```

```

Build impact: main + tests build clean, **0 warnings**; targeted suite **6/6 pass**; full-suite run
**314/315 pass** — the single abort is the known environment-dependent `RealMouseDrag` test (Path of
Exile 2 running, physical-mouse injection no-ops; see ⚠️ below and rerun with the game closed for a
clean 315/315).

## What shipped — TASK 42: top bar redesign (2026-09-22)

Full record: **`TASKS/task-42-top-bar-redesign.md`**. Creator directive: "forget this one dog plan
bullshit. Our one plan is replacing the top menu bar with something usable." The old bar's six
widget grammars (sliding pills, dots, badges, buttons, hidden sign-in context menu, live-window
status) collapsed into **ONE surface rendered by the FIRST decision — Record or Stream**:

- **Mode switch:** one segmented **REC|ON-AIR** toggle (`SegmentToggle`/`SegmentLabel` styles).
  Going back = one tap on the other segment. Runs idle-only; retires while running.
- **Record world:** switch + **Start Recording** — no YouTube identity at all.
- **Stream world:** switch + **Go Live** + Test + account zone (Sign In until connected; then the
  avatar, right-click Change Account/Logout). **Test is a child of Stream** — procs only ON-AIR-armed
  AND signed-in (`ShowTestButton`/`CanStartTest`).
- **Running:** one reality line `● REC|LIVE|TEST 00:12:34` (green/red/gold `RunningDotBrush`) + End.
- **Gear** moved up from bottom bar, ~3 wordmark letters past the brand, one click = Settings / Bug /
  Feature / About menu (`GearButton_Click`). Bottom-bar gear removed. Task 40 Unit B is DONE by this.
- **Sign-in = the account-confirm step:** no Google API enumerates machine accounts; OAuth is
  single-account, so Switch Account re-runs the chooser (`login_hint`+`select_account`) — login and
  account-confirmation are one surface. Existing `ChangeAccountCommand`/`LogoutCommand` resurface via
  the avatar.
- **PRIVATE/TEST chips gone from the bar** (dev-phase forced-private becomes an OPTION at ship).

**Good Dog** — `ytLive.Tests/TopBarModeTests.cs` (one `[Fact]`, `RealAppHost.Run`): default record
world → arm ON-AIR → sign-in/avatar/Test gating flips → one-tap flip back → direct stream status
changing + running reality values. Also folded in: TASK 41's latent **Test pipeline bug fix** —
`BeginTestStream` now arms `OnAirPillOn` explicitly (unarmed → encoder booted with zero outputs →
"At least one output is required" → forced stop cascade). The TestStreamTests gate updated to match.

## ⚠️ Around the task

- **Full-suite run today: 314/315** — the one abort is the pre-existing
  `LayerReorderPersistenceTests.RealMouseDrag_OnTheLayerList_PersistsTheReorder`, which injects
  REAL physical mouse input (`SetCursorPos` + `mouse_event`, see its own docstring) and no-ops while
  another window interferes. Cause observed 2026-09-22: **Path of Exile 2 + NVIDIA Overlay were
  running** (fullscreen-game window hides the test window's rows; the drag never lands → reorder
  assert fails). Close the game before running that test; it is unrelated to TASK 42 and has passed
  on clean reruns previously.
- **Manual verification owed** (needs a real run on Windows): the app is a new build number when
  next launched — check the new one-surface bar (switch ↔ worlds, gear menu, reality line).
- The app may be **RUNNING** — an in-place build fails MSB3021/MSB3027 until closed (temp-OutDir
  workaround in ai.md). Close it before the manual pass.
- Full-suite note: the pre-existing real-camera startup flake did **not** occur in the 315/315 run.
- Test-env trap (recorded in the TASK): a dev machine's saved OAuth session loads synchronously and
  makes `IsConnected` come back true in the VM ctor — signed-in-world tests must force
  `vm.IsConnected = false/true` explicitly.
- `subscriberCount` rounded to 3 sig figs (YPP); carried. YPP slice 2 needs re-consent — do NOT
  merge with other units.
- Polar product `d105dfa1…` still `$99/yr` — must become one-time before launch (carried).
  `MARCOM.md`/`MONETIZATION.md` gitignored — never commit.

## Next step

Scope-check the declared list → build (0 warnings) → full test suite rerun → **one commit** for
TASK 42 (docs + code same change). Push only on the user's say-so. Then **TASK 40 App Settings
round** is queued (`TASKS/task-40-app-settings-round.md`) — units **A (camera) → C (defaults) → D
(accent)** remain (B/gear shipped early); Unit A's SharedReadOnly control-write question is the one
genuinely uncertain technical point — run its mitigation ladder before a third guess.

## Critical working rules (unchanged, still binding)

- **Good Dog = ONE integration test per change.**
- **Scope lock:** declare the file list before editing; `./scripts/scope-check.sh` before commit.
- WSL builds use the Windows dotnet host (`/mnt/c/Program Files/dotnet/dotnet.exe`, quoted paths).
- One runtime model, no model switching, no compaction summaries (user directive).
