docs(todo): mark 6 bug-hunt findings fixed (decorations, presence, denoise)

Closes the avatar-decoration cluster (live-update pub/sub, CDN-override
thumbnail, profile-404), the DND badge color, and the DenoiseTester
model-node leak + async mounted-guard — commits 29ff1654 and c9d9d914.

 **Voice / video calls**
 
-- [ ] **[Med]** `DenoiseTester.play()` (Settings → Calls A/B model test) leaks the denoise model node — calls `ctx.close()` but never `denoise.dispose()` (inconsistent with `stopLive`, which disposes) → leaks the DeepFilterNet/DTLN worker/WASM per press. `DenoiseTester.tsx:267-300`.
+- [x] **[Med]** `DenoiseTester.play()` (Settings → Calls A/B model test) leaks the denoise model node — calls `ctx.close()` but never `denoise.dispose()` (inconsistent with `stopLive`, which disposes) → leaks the DeepFilterNet/DTLN worker/WASM per press. **FIXED** (`c9d9d914`): `stopPlayback` now mirrors `stopLive` (dispose model + gate), and a generation token also closes the rapid-click / stop-during-load / unmount-during-load leak windows (3 review passes, all 6 interleavings traced).
 - [ ] **[Med] [live]** PiP auto-spotlight never released on return to the call room — the release branch sits inside the `if (!pipMode) return` guard, so screenshare→PiP→back leaves spotlight forced on and `pipAutoSpotlightRef` stuck `true`. `CallEmbedProvider.tsx:733-744`.
-- [ ] **[Low]** DenoiseTester async paths (`getUserMedia`) have no mounted-guard → ctx/stream leak + setState-after-unmount if Settings closes during the mic prompt.
+- [x] **[Low]** DenoiseTester async paths (`getUserMedia`) have no mounted-guard → ctx/stream leak + setState-after-unmount if Settings closes during the mic prompt. **FIXED** (`c9d9d914`): a `mountedRef` guards `startLive`/`startRecord` after the `getUserMedia` await (and `play()` after its model load); the ref is set on mount, not only cleared on unmount, so it survives a StrictMode/Activity remount.
 - [ ] **[Low]** Soundboard 30s safety timeout never cleared on natural clip end (`CallSoundboard.tsx:115`); `PrescreenControls` `PermissionStatus.onchange` not removed on unmount (`PrescreenControls.tsx:22-28`).
 - [ ] **[Low] [live]** Call-to-call switch disposes the embed without an explicit `HangupCall` → possible transient ghost RTC membership until EC's unload-leave fires.
 
 **Theming / visuals**
 
-- [ ] **[Med]** `invalidateDecorationCache` clears the module cache but has no pub/sub → changing **your own** avatar decoration doesn't update live in already-mounted avatars (timeline/members) until remount. Add a listener set / bump counter. `useAvatarDecoration.ts:67`.
-- [ ] **[Med/Low]** Decoration picker grid thumbnails use the raw `DECORATION_CDN` constant instead of `decorationUrl()`, ignoring the `VITE_DECORATION_CDN` override → broken thumbnails if decorations are repointed. `ProfileDecoration.tsx:51`.
+- [x] **[Med]** `invalidateDecorationCache` clears the module cache but has no pub/sub → changing **your own** avatar decoration doesn't update live in already-mounted avatars (timeline/members) until remount. Add a listener set / bump counter. `useAvatarDecoration.ts:67`. **FIXED** (`29ff1654`): per-user listener set notified on invalidation (+ clears the give-up counter); concurrent re-fetches de-dupe via the existing `pending` map.
+- [x] **[Med/Low]** Decoration picker grid thumbnails use the raw `DECORATION_CDN` constant instead of `decorationUrl()`, ignoring the `VITE_DECORATION_CDN` override → broken thumbnails if decorations are repointed. `ProfileDecoration.tsx:51`. **FIXED** (`29ff1654`): grid uses `decorationUrl(slug)`.
 - [ ] **[Low]** Seasonal "Auto" is computed once at mount (no ticker, unlike NightLight) → won't flip across a holiday-window boundary in a long-lived session. `SeasonalEffect.tsx:100`.
 - [ ] **[Low]** Selecting seasonal "Auto" while a chat background is set is a silent no-op (asymmetric mutual exclusion — SeasonalEffect early-returns when `chatBackground !== 'none'`). `General.tsx:550`.
-- [ ] **[Low]** Decoration settings fetch the `/{field}` sub-resource → console 404 for users with no decoration set. `ProfileDecoration.tsx:79`.
+- [x] **[Low]** Decoration settings fetch the `/{field}` sub-resource → console 404 for users with no decoration set. `ProfileDecoration.tsx:79`. **FIXED** (`29ff1654`): reads the full `/profile/{userId}` (matching `useAvatarDecoration`); PUT/save path unchanged.
 
 **Threads / presence / UX**
 
-- [ ] **[Med]** `PresenceBadge` renders DND (`unavailable` + `status_msg:'dnd'`) as a **yellow "Idle"** badge + label, while `PresenceRingAvatar` correctly shows **red** — inconsistent. Give the badge the same `status === 'dnd' → Critical` + "Do Not Disturb" branch. `Presence.tsx:17-59`.
+- [x] **[Med]** `PresenceBadge` renders DND (`unavailable` + `status_msg:'dnd'`) as a **yellow "Idle"** badge + label, while `PresenceRingAvatar` correctly shows **red** — inconsistent. Give the badge the same `status === 'dnd' → Critical` + "Do Not Disturb" branch. `Presence.tsx:17-59`. **FIXED** (`29ff1654`): badge now matches the ring + settings picker (Critical / "Do Not Disturb", `'dnd'` sentinel line suppressed).
 - [ ] **[Med]** Collapsible-message threshold is hardcoded (`COLLAPSE_MAX_HEIGHT = 320`), but the docs claim it's "configurable in Settings → Appearance (default 20 lines)" — unimplemented. Add the setting + control, or fix the doc. `MsgTypeRenderers.tsx:38`.
 - [ ] **[Med/Low]** In-app toast container has no visible cap / scroll — a burst of messages across rooms while focused stacks toasts unbounded and can cover the viewport. Cap visible N or `overflow-y:auto` + max-height. `LotusToastContainer.tsx:223-247`.
 - [ ] **[Low]** "Unread First" room sort leaves the (larger) read portion unordered — no activity fallback for the equal-unread case. `Home.tsx:213-222`.
