Code-read + upstream-issue triage this session:
- 41.7.0 / crypto-wasm 18.3.1 does NOT fix KE-1 (no OTK/upload change; #5200
still open) — the SDK-pin remediation lever is closed.
- Confirmed root cause = rust-crypto store <-> Synapse OTK divergence; the
leading web trigger is that cinny never requests persistent storage, so the
IndexedDB crypto store is evictable while the localStorage session survives.
- New buildable preventive mitigation: navigator.storage.persist() on login
(+ multi-tab guard, 400-loop recovery prompt). Added as §6 with a secondary
KE-2 to-device-validation hypothesis and capture discriminators.

Add HSTS + Permissions-Policy + the standard X-Frame/X-Content/Referrer set to
the contrib nginx (443 block) and caddy examples; fix the caddy SPA try_files
fallback (stray space). Generic (no homeserver-specific CSP). The real prod
config lives in the matrix repo. P6-4 trimmed to headers only — patch-package /
types-drift / build-config skipped (see LOTUS_TODO).

Forward: checkbox multi-select room picker + "Send to N rooms" batch send
(Promise.allSettled). Full success auto-closes; partial failure keeps the dialog
open with a "Forwarded to X/N — failed: …" summary and prunes the selection to
only the failures (retry won't duplicate to already-sent rooms). Content builder
extracted to a unit-tested forwardContent.ts (edit-forwarding, reply-strip,
undecryptable-refused; 4 tests).
Bookmarks: BookmarksPanel resolves each saved message's live event (useRoomEvent)
so previews reflect edits and show a deleted indicator for redactions; the stored
snapshot stays as the fallback while loading, on fetch failure, or after leaving
the room. Stored bookmark shape unchanged.
Gates: tsc/eslint/prettier clean, build OK, 665 tests. Reviewed (dup-resend on
retry + Checkbox readOnly fixed).

CallControl now sends the new io.lotus.set_deafen action (join-gated via
forceState) on every deafen / screenshare-audio-mute toggle + on join, ALONGSIDE
the retained iframe-DOM .muted hack (transitional). Against the current pinned
bundle the action is immediately error-replied + swallowed by .catch — inert, no
timeout. Reordered toggleSound() to commit state before setSound() so the sent
deafen value isn't inverted.
Phase 2 (after the fork is published): bump the pin lotus.1 -> lotus.2 and delete
the DOM hack. Docs: HANDOFF §12.4, LOTUS_TODO P6-2, LOTUS_BUGS.

Dep triage recorded (zero shipped exposure; SDK now 41.7.0 stable; dompurify
removed); Needs Verification rows for the audit-wave fixes (scheduled-cancel,
emoji lazy-load, SW precache, desktop CSP smoke).

TODO: P4-7 already-implemented [x]; P4-6 mozilla test enablement verified live;
Audit-3 researched → deferred tracking MSC4427 (banner_url proposal, unmerged);
P3-8 Thread Panel now carries the complete SDK-evidence-backed build plan
(threadSupport side effects, local-echo gap, receipt fix, 4-agent partition) —
ready for its own session. BUGS: N127 removed, Big #5 (backgrounds/seasonal)
done, CDN env-var closed (VITE_DECORATION_CDN exists), test count updated, KE
section points at the new investigation kit.

Element Call is now consumed as our self-built fork
(@lotusguild/element-call-embedded); wire up its previously-dormant
capabilities and document the fork as live.
Soundboard (P5-15): a call-bar button plays user-uploaded audio clips into the
call as a real published track (io.lotus.inject_audio) plus local playback.
Clips are uploadable like emoji/sticker packs, stored in io.lotus.soundboard
account data (synced across devices). Gated by a Settings toggle + volume.
Quality controls (P5-31): per-user mic/screenshare bitrate + screenshare
framerate (Settings -> Calls), applied via io.lotus.set_quality clamped to any
room cap. Room admins set caps and hard call-permissions (allow_screenshare /
allow_camera) in Room Settings -> Voice; the call bar hides blocked buttons.
- New: CallSoundboard, useSoundboard, soundboardClips; RoomQuality,
useCallQuality, callQuality (+ unit tests).
- Optimistic-write RoomQuality admin UI (no stale-state clobber).
- Docs: mark EC fork live across README/FEATURES/TODO/BUGS/TESTING; add D2
manual-test steps.
Numeric quality caps are client-cooperative; screenshare/camera permissions are
hard-enforced server-side (see LotusGuild/matrix voice-limit-guard).

- avatarDecorations: resolve the decoration CDN base from VITE_DECORATION_CDN at
runtime, falling back to the DECORATION_CDN literal (kept intact so the sync
script + tests still parse it). Lets a deploy repoint the CDN without a code
edit. Guarded for the tsx test runner (import.meta.env undefined there).
- LOTUS_BUGS: close N127 — the denoise dev-injection gap dissolved with the A7
cutover (no getUserMedia shim is injected anymore; denoise is in-source in the
EC fork), so there is nothing to inject in dev.

- scheduledMessages.test.ts (9): pins the MSC4140 request shape (PUT to the room
send endpoint with the org.matrix.msc4140.delay query, POST cancel/restart to
/delayed_events with the unstable prefix), the delay-floor math (Math.max(1000,
round(sendAt-now)) — "now"/past targets still yield a valid >=1000ms delay),
rounding, and url-encoding.
- lotusDenoiseUtils.test.ts (9): model-catalog data integrity + isMLDenoiseSupported
feature detection across AudioContext/webkit/getUserMedia.
- Bug found + fixed: isMLDenoiseSupported used `!!AudioWorkletNode`, a bare global
reference that throws ReferenceError (not returns false) on a browser with
AudioContext but no AudioWorkletNode binding. Switched to `typeof` so the
detection helper reports unsupported instead of throwing. Regression test proven
to fail on the old code.
Suite now 545 tests (4th real bug caught by the prevention work).

callSounds.ts had no tests despite 106 lines of user-facing audio logic. Adds 13
tests (mocking AudioContext) pinning: the chime/soft/retro join+leave melodies
(frequencies, oscillator types, stagger), the click-avoidance gain envelope and
osc->gain->destination wiring, and the defensive contracts — unknown style is a
no-op that never creates a context, a throwing AudioContext constructor is
swallowed, and the shared context is reused / recreated-when-closed / resumed-
when-suspended. Suite is now 527 tests; refreshed the stale count in LOTUS_BUGS.

LOTUS_BUGS.md: new Encryption/E2EE section tagged EXTREME complexity +
planning-session-required for a senior-engineer deep dive — OTK upload
conflict storm (KE-1), Element Call media-key distribution failures causing
audio/video dropouts (KE-2), a timeline decryption error (KE-3), and
MatrixRTC delayed-event timeouts (KE-4). All observed live 2026-06-30; not
caused by the EC fork work. Plus a non-developer ELEMENT_CALL_TEST_CHECKLIST.md.

Switch to @lotusguild/element-call-embedded@0.20.1-lotus.1 (our self-built
fork) and turn on the source-level features it adds:
- #1 denoise CUTOVER: in-source ML denoise (lotusDenoiseSource=1) replaces
the build-time getUserMedia shim — removed the shim injection from
vite.config.js (denoise/ assets still shipped; the processor loads them).
Survives reconnects (fixes A7).
- #2 call-state: CallEmbed consumes io.lotus.call_state; useCallSpeakers /
useRemoteAllMuted prefer it over scraping EC's DOM (DOM fallback kept;
empty payloads ignored).
- #4 focus: CallControl.focusCameraParticipant sends io.lotus.focus_participant
(works during screenshare), replacing the DOM tile-click hack.
- #5 theming: lotusTransparent=1 (native transparent background).
- #6 decorations: LotusDecorationPusher sends each member's decoration URL
via io.lotus.decorations -> rendered on in-call tiles.
#3 soundboard / #7 quality ship dormant (EC-ready; no host UI sends them yet).

Captures the plan to fork element-hq/element-call and build it from source for
true ownership of the in-call experience (decorations, focus/screenshare,
reconnect mic, native theming, call-audio injection) — none of which are fixable
against the prebuilt @element-hq/element-call-embedded bundle we ship today.
- New HANDOFF_ELEMENT_CALL_FORK.md: self-contained plan for a fresh session
(current architecture, full file inventory, phases, new-repo decision, the
denoise-shim interaction, doc corrections).
- Tagged every related note with [EC-FORK] + links: README (For Developers),
LOTUS_BUGS (EC limitations), LOTUS_TODO (soundboard, denoise, soundboard
cross-origin correction), LOTUS_FEATURES (call section).

Verified passing: A2, B1-B4, C1, C3, D. Re-fixed and awaiting re-test: A1
(ringtone loudness), A3/A4 (caller decline notice), G1 (All-muted badge).
Documented A5/A6/A7 as known Element Call iframe-boundary limitations.

Two stale facts in README.md: it said "Forked from Cinny v4.12.1" (we've since
synced through v4.12.3) and referenced the logo as lotus_chat.png (the file is
public/res/Lotus.png). CONTRIBUTING.md is intentionally left as upstream
Cinny's and is not modified.

Per request, removed completed/resolved items (full history is in git) and
reorganized both into actionable form.
LOTUS_BUGS.md (864 -> 77 lines): dropped ~120 fixed-and-verified entries plus
all false-positive / won't-fix records. Now two clear sections: "Needs
Verification" (fixed in code, awaiting live test, cross-referenced to
LOTUS_TESTING.md) and "Open — Actionable" (grouped by theme).
LOTUS_TODO.md (771 -> 694 lines): removed completed [x] blocks (they live in
LOTUS_FEATURES.md) and consolidated the done-but-untested ones into a single
"Done — Awaiting Verification" index pointing at LOTUS_TESTING.md. Pending
[ ] items and nested roadmaps (e.g. DeepFilterNet/FRCRN under P5-30) were
preserved exactly (verified 42 -> 42); empty sections removed.

- Add grow="Yes" to ChatBgGrid and SeasonalBgGrid containers so they
expand to fill their flex parent — without it the Box shrank to one
column (~76px wide) because folds Box defaults to display:flex and
the wrapper is a flex-row with no explicit width.
- Mark N4 (PollContent) FIXED ✅ VERIFIED in LOTUS_BUGS.md after
confirmed pass on default Cinny themes and Lotus TDS.
- Mark B1 and B4 PASS in LOTUS_TESTING.md.

Security & data persistence (N97–N100): plaintext access token storage
detail, normal logout wiping user prefs via localStorage.clear(), sync
ERROR freezing the loading screen, unrestricted CSS classes on <pre>.
PWA/SW/notifications (N105–N109): missing SW notificationclick + push
handlers, decrypted E2EE message body leaked to OS notification center,
missing maskable PWA icon, auth media URLs producing 401 in notification
icon/badge fetches.
Lotus feature internals (N113–N120, N128): reminder read-modify-write
race, fire-and-forget removeReminder silently drops on network failure,
setInterval restart on every reminder state change, useCallSpeakers
rebuilds speaker set from mutation batch only (drops current speakers),
static NodeList misses mid-call tile additions, CDN outage silently wipes
decoration catalog, CDN URL drift between two source files, patch-folds
silent exit-0 when patch target not found.
Call system & noise suppression (N122–N127): setMediaState Promise hangs
forever if EC omits DeviceMute echo, focusCameraParticipant drops tile
click if spotlight isn't ready in 2 rAFs, denoise cleanup() leaks
AudioWorklet gateNode, postMessage wildcard '*' origin, PiP position
NaN on corrupt localStorage, denoise shim inactive in vite dev.

Both Retry and Leave called the same dismiss function; Retry implied a
reconnect attempt that never happened. Collapsed to a single Back button
that honestly describes returning to the prescreen.
docs: correct Gemini audit entries — sanitize-html not DOMPurify (Claim A),
retract inaccurate LiveKit replaceTrack soundboard approach (Claim B,
contradicts confirmed cross-origin iframe constraint), expand N95 fix note
to clarify track-stop vs AudioContext-suspend distinction.
docs(testing): add L1 N95 reproduction guide; update A7 to reflect single Back button.

#1 documented as implemented (focusCameraParticipant + MemberGlance
"Focus camera" menu); #4 ringtone selection landed, with the remaining

Mark items resolved by commits b7e1f89c / d2946c00 / 0394fce9 / 203568c9
as FIXED, and record the false-positives surfaced during the audit
(useMatrixEventRenderer null contract, Lobby getRoom already memoized,
RoomTimeline/RoomInput already wrapped by RoomView's ErrorBoundary).
