feat: enhance /webrtc/ice_gather_test and add /webrtc/net_info for zero-candidate diagnosis

feat: add /webrtc/negotiations and /webrtc/ice_gather_test diagnostics

feat: add /webrtc/turn_config and /webrtc/turn_probe diagnostic endpoints

Prefer static TURN credentials over Metered

Improve Metered ICE failure diagnostics

Load CodeFormer repo modules automatically

Install httpx and capture disconnect snapshots

Handle non-awaitable aiortc replaceTrack

Fix outbound video binding

Refine avatar diagnostics and prune legacy assets

fix(webrtc): tolerate pre-existing video sender and avoid 500 on duplicate binding

fix(webrtc): make outbound video transceiver creation idempotent (resolve 'Track already has a sender')

fix(webrtc): use sendrecv transceiver for outbound video to ensure inbound track reception (black feed fix)

feat(video): extended outbound diagnostics (luma, placeholder vs real frame counts, binding guard)

chore(ui): remove top bar placeholder buttons to focus on video diagnostics

feat(frontend): stage timeline, frame counter, black frame detection, connection path badge

feat(webrtc): add negotiation instrumentation and pipeline init guard

chore(static): remove legacy webrtc_prod.js and document static asset inventory

feat: replace index.html with enterprise-grade UI

fix: improve webrtc server stability and diagnostics

feat: upgrade frontend to enterprise-grade premium design

Add ICE sampling & watchdog + /webrtc/ice_stats endpoint for prolonged checking diagnostics

ICE diagnostics: expose TURN/STUN counts; client skips futile relay retry w/out TURN

Add compatibility /webrtc/* wrapper endpoints to resolve 404s during prefix transition

Fix SyntaxError: remove duplicate inner global _peer_state

Mount webrtc router at /webrtc after removing internal prefix

Align router prefix strategy: remove internal /webrtc prefix (app supplies it)

Fix double /webrtc prefix causing 404s (mount router without extra prefix)

Add explicit global _peer_state in async with block

Force space rebuild - trigger restart

Fix duplicate global _peer_state declaration

Fix WebRTC router path: add /webrtc prefix

Fix critical syntax error: add missing global declarations for _peer_state

Add comprehensive WebRTC connection failure diagnostics

fix(webrtc): resolve connection retry hangs with aggressive cleanup

feat(webrtc): integrate pipeline cleanup on connection state changes

fix(pipeline): resolve temporal reuse bug, add resource monitoring and cleanup

feat(debug): inbound raw frame counter + expose raw_frames_in for WebRTC diagnostics

feat(logging): add periodic pipeline stats + outbound video relay diagnostics (fail counters, placeholder timing)

fix(pipeline): indent codeformer_error; chore(video): add placeholder diagnostic logging

chore(pipeline): improve CodeFormer import diagnostics and expose codeformer_error

fix(video): correct pipeline indentation + disable color bar pattern after first real frame

fix(pipeline): disable naive small-face upscale causing black box artifact; expose model path

feat(pipeline): ensure model dir tracked without weights; update swap pipeline changes

feat(webrtc): hybrid inline-if-idle processing, latency & queue metrics, pipeline stats endpoint

feat: brightness & similarity diagnostics in swap pipeline (overlay annotated)

docs: document MIRAGE_PROC_MAX_DIM & MIRAGE_DEBUG_OVERLAY; add swap debug vars; capture active providers

feat: add detailed swap diagnostics counters & logging

fix: handle permission denial on /app/models symlink setup fallback

chore: remove deploy script; add persistent model storage & diagnostics
