Current Status

Last updated: 2026-08-29

This is the current execution index. Git history owns completed timelines; verification status owns evidence boundaries.

Production

• https://share.bonfire.icu runs exact application/runtime revision 9b213739b274b5c1a8f87eb1d2946edc144b9ad2, release 9b21373, wire screener-v17, from /opt/screener/releases/9b21373. The immutable runtime tar SHA-256 is 667f5c7e65420e9dff792c472af7869219ad0133770e4ec344bb25faca67c07e; its 41-file manifest SHA-256 is b389a2bddf4b0620b0eb3b18fec22dfc497c026088533a9ce86bc1b4c04b3f8e.
• The served Browser entry references assets/index-BmE4pIwS.js; the public asset SHA-256 is 70875bbd57d8bd3bacebaf2d41f4a0d433dfce227ffd5cdd5cff38d64db84863. Public /healthz returns 200. The release postflight found Screener, LiveKit, coturn, and nginx active with zero restarts.
• Production enables SQLite room authority at /var/lib/screener/rooms.sqlite; live participants, routes and media remain process-only. A controlled restart retained the room authority and Host-owned capture while the Viewer rebuilt media without a page refresh. Lightweight mode remains available when ROOM_DATABASE_PATH is unset and reacquires a room rather than persisting the old authority.
• Site access uses a stateless 24-hour rolling idle cookie. An active site-authorized page renews it hourly through the existing status request; Viewer-grant admission remains independent and cannot create or renew it.
• Public media listeners remain STUN-only UDP 3478 and LiveKit UDP 7882. Web ingress is TCP 80/443; Node 8787 and LiveKit control/signaling 7880 are private. TURN, ICE/TCP, media TCP, TLS relay, port 5349, and relay ranges are disabled.
• Browser video uses the content-independent H.264 sender gate with VP8 fallback, plus the locked pre-share VP8 | Auto | H264 Host selector and resolved codec display. Video retains contentHint = "motion"; audio uses music. The SFU publisher uses the Host's one codec decision, leaves representation construction to pinned LiveKit, enables Dynacast, uses server send-side BWE, keeps AdaptiveStream disabled, and configures no external ICE servers on Browser SFU PCs.
• Screen audio provides live 64/128/192 kbps ceilings with 128 default. SFU publication uses stereo, DTX off, and RED off. Early autoplay presentation is gated by current media connection state.
• The living-room presentation is deployed with Chinese, English, and pure-visual modes, light/dark themes, one Host/Viewer stage language, progressive per-Viewer diagnostics, responsive identity topology, and reduced-motion behavior. Fresh Browsers start in visual mode; explicit choices persist locally.
• Native-edge local convergence defaults on for each new share and remains a pre-share Host opt-out. The adjacent default-off peer-only policy excludes all SFU paths for that share generation. Both policies lock while sharing.

Current Source

• Canonical source uses the strict screener-v17 Browser/server contract. Optional SQLite stable authority, non-expiring local preferred code, atomic room replacement and the Host codec selector remain implemented; production selects stable storage. Graceful restart, crash, timeout and network loss use one reconnect state. LiveKit room teardown cannot stop Host-owned capture.
• One event-driven controller owns the committed graph and one room-serial child operation. Initial direct acquisition uses a five-second foreground window; exact transport-connected progress may retain that candidate through the total deadline, while first decoded frame remains the only commit proof. SFU provides working media before finite background direct convergence. Healthy decoded edges remain sticky. A connected Viewer's advertised effective capacity survives sharing-generation graph replacement and is cleared only when that Viewer departs or the room is deleted.
• WebRTC/LiveKit own media adaptation. With the per-share convergence gate enabled, one fresh degraded native edge may enter the existing serial route operation after availability work. A P2P candidate commits only after the same Viewer sees first-frame readiness plus three fresh windows that strictly improve delivered resolution or rounded FPS without regressing either. Peer candidates stay first; bounded SFU is only the suffix for whole-Host-root degradation and retains native publication proof. The gate defaults on in source and remains a locked pre-share opt-out.
• Screener has no custom SFU layer list, quality score, layer selector, all-pairs probe, parent-wide prediction or periodic rebalancing. P2P and SFU still recover their current route before actual failure enters reassignment.
• Viewer hidden/freeze/pagehide suppress decoded-stall routing authority; visible/resume/pageshow rebaseline and rearm current-frame proof. SFU pagehide no longer triggers LiveKit's automatic disconnect. Native Viewer controls still own playback, and manual reconnect stays on the current route.
• Host, Viewer, join, and access surfaces share the living-room presentation model. Room codes, invitation URLs, the current display name, selected participant details, route labels, and metrics remain visible in visual mode; couch and topology identities remain visible across expression modes and bounded deep trees scroll within their own surface.

Source/Production Delta

• Production application code is exact revision 9b213739b274b5c1a8f87eb1d2946edc144b9ad2; the following truth checkpoint changes documentation only.

Current Milestone

The living-room Host/Viewer presentation, expression modes, diagnostics, and responsive identity topology are deployed on the measured route, generation-owned presentation, and endpoint-capacity model.

Active Boundaries

• Desktop Host background capture remains unconfirmed. The current-browser screening did not reproduce a Host-page drop; accepted Viewer lifecycle work prevents frozen JavaScript wall time from becoming an immediate route failure but is not capture keepalive.
• Current-path quality can drive local convergence in source and production. Both default it on with a pre-share Host opt-out. Weighted/global optimization remains parked.
• Repository simplification does not change or deploy product behavior beyond deleting proven dead private surfaces.
• Native/executable senders, shared encode, and distribution packages remain outside the current release. Current UI refinement is presentation-only and does not authorize route or media-model changes.

Current Hold

No source or deployment P0/P1 is open. Sanitized route logging remains enabled for the pre-release canary.
