Viewers who cannot reach the media get it through the server: a file on
any member's computer, a link passed on by a member ("Through me") or
fetched by the server ("Server fetches it", password-protected servers
only), and Jellyfin items for guests without an account, sourced by
whoever put them up with their own sign-in (or a pasted link's key),
which never leaves their machine. Fixes guests on a dedicated server
without a Jellyfin login being blocked.
The source dials /r/.../source (works behind NAT) and answers pulls with
an adaptive in-flight window (2 x rate x min RTT, 256 KiB..8 MiB). The
server keeps a memory-only buffer of 1 MiB slices sized like a viewer's
mpv buffer (pinned head/tail, 64 MiB back, 256 MiB ahead), fills it with
one sequential pull at a time (blocked viewers first, newest request
only), fetches nothing while nobody watches through it, and drops it on
the next swap or stop. Measured with mpv through shaped links
(tool/relay_e2e.dart): 400 Mbit/s seeks ~0.03 s; 40 Mbit/s no stalls,
3 viewers cost the source ~1x the bytes.

- Host/swap send refs only; pasted Jellyfin links become refs; the host
hands the relay its own app-obtained credential.
- Each viewer resolves with their own account (token in a header) or
via the relay, else a clear blocked card with Link account.
- Per-account progress reporting (Playing/Progress/Stopped), 401 marks
the account expired.
- Previous/next episode in the controls (< > / Shift+P/N), floating
Next episode pill near the end, auto-advance countdown (one
designated swapper), track carry-over per series.
- Swap panel uses the shared MediaPicker; browser location remembered
per server and opens on the current series.
- Fix: states are applied one at a time (a stale pause could land
after a newer play).

- Media can be a Jellyfin ref {serverId, itemId, mediaSourceId, title,
subtitle, runtimeSecs}; the server never stores or broadcasts a URL
or token for it.
- Optional server-side Jellyfin credential (serve map / --jellyfin
file) enables GET /j/<sid>/<token>/<itemId>: range-faithful proxy of
the active item only, exact client header fields, upstream aborted on
disconnect, bytes counted. welcome.relayUrl / state.relay advertise it.
- Members report jf access (own account vs relay).
- /m now sends the real Content-Type (Relic overrode it).

- User seeks are intercepted at the player (SyncPlayer), previewed
locally, sent once 300 ms after the drag ends; own echoes are matched
by seekSeq and never re-applied; the landed check can't reapply a
stale target. 1 s position poll removed.
- ping/pong clock offset (min-RTT ClockSync); positions use server time.
- Reports carry duration; buffer gate is min(4 s, remaining - 2 s);
new finished transport instead of a HELD stall at the end.
- cache/readahead 150 s, 256 MiB demuxer cache, pins read back.
- Resumed reports put a stale ready member back in the set; hello.resume
takes over the old member after an unclean drop (no ghost).
- Docs: roadmap rendering findings (HW path works; shaders verified).

- serve(Map config, events) is the one server entrypoint: the app
hosts it via Isolate.spawn (crash surfaced on the Host card, logs
forwarded as [server]); bin/server.dart is the dedicated server,
compiled into the bundle as watch-together-server. --headless gone.
- Host identity via a per-hosting hostKey in hello, replacing the
loopback heuristic.
- Rename room -> server across code, files and wire (t:"state",
/health name); protocol bumped to 5.
- CI compiles the server binary; isolate smoke tests in server and
desktop suites. Docs updated.

- Reject non-finite numerics at protocol parse and in the engine
(a 1e400 seek became Infinity and broke every broadcast).
- Reject empty swaps; sanitize URL-looking media names.
- Blank password = open server; defaults no longer 'change-me'.
- Loopback peers (the in-process host) can't be kicked.
- /health no longer exposes media/transport; file URLs use the
host the client dialled instead of 127.0.0.1.
- Count served bytes as streamed, not as requested.

64 KiB rejected normal 128px PNGs. 128 KiB fits any 128x128 PNG
(raw <= 64 KiB, worst-case base64 ~95 KiB chars) while still
bounding abuse. PNG kept for transparency. Pipeline now measures
the encoded base64 against RelayConstants (was checking the wrong
variable with its own 512 KiB limit) and drops dead crop code.
Server policy, still v4. Trade noted: avatars ride the 1 Hz room
broadcast, uplink scales with cap; hash-reference follow-up later.
