molluskandClaude Opus 4.8 961705ffa9 feat(game): broadcast game presence (GOSSIP_PROTO 3) + per-game background
Steps 5-6 of game detection. BREAKING wire change — bump everyone.

Wire (step 5):
- PeerState.game: Option<String> (display label only — never appid/source).
- SelfPresence.game + to_state carry it (single self-state builder).
- GOSSIP_PROTO 2->3, GOSSIP_SIG_DOMAIN v3, version comment bumped together;
  Cargo MINOR 0.3.0 -> 0.4.0 per VERSIONING.md. v2/v3 isolate into
  different topics + signature domains, so a coordinated redeploy is
  required (same as the W4 avatar bump).
- Gossip ingest sanitizes incoming game via sanitize_game_label (bidi/
  control strip, 64-char/256-byte cap); empty -> None.
- Bonus security fix (Codex find): reject inbound gossip frames over a
  128KB cap BEFORE serde_json::from_slice — a legit Announce with a full
  48KB avatar is ~49KB, so this bounds allocation abuse with headroom.

Core wiring:
- Spawns the detector at startup; consumes its watch channel in the main
  select. Detection runs continuously (for the local background); the
  broadcast is gated by game_presence_enabled (opt-in, default OFF).
  New commands: SetGamePresenceEnabled (immediate publish/clear, D8),
  SetGameOverride, SetGameProcessMap. New event: GameChanged.
- game_presence_label sanitizes the outgoing label too.

Background switch (step 6):
- GUI handles GameChanged: stores current_game, swaps background to the
  per-game override (config.game_backgrounds[id]) or falls back to the
  W16 default; reuses the existing cached-handle path (no redraw flicker).

397 lib tests (all green), clippy --all-targets clean, full binary builds.
Remaining: step 7 UI (opt-in toggle, roster 'Playing' text, manual
override control, Settings game-backgrounds + process-map editors).

molluskandClaude Opus 4.8 9e8c8b4ace refactor(core): single SelfPresence self-state builder
Core reconstructed PeerState in five command branches (join, mute
toggle, avatar change, screen-share start/stop), each repeating the full
field list. Factor a SelfPresence struct holding the sticky identity
fields (name + avatar) with a to_state(is_muted, addr, sharing) builder
that folds in the volatile per-announce fields, so the PeerState literal
lives in one place. This is the precondition for adding a broadcast
game-presence field without editing every call site.

No behavior change. +1 unit test (359 lib total path).

molluskandClaude Opus 4.8 efadc228eb fix(files): keep serve connection alive until fetcher has the bytes
windows-build / windows-build (push) Has been cancelled
cargo-deny / cargo-deny (push) Has been cancelled
Chat file fetches failed 100% of the time with "file fetch: read failed:
read error: connection lost" (both images and arbitrary files, both
directions). Root cause: the FileRouter serve handler called send.finish()
and immediately returned Ok(()), which dropped the Connection. In QUIC,
finish() only marks the stream's EOF -- it does not wait for the written
bytes to be delivered and acknowledged -- so the connection's
CONNECTION_CLOSE raced ahead of the still-in-flight stream data and the
fetcher's read_to_end aborted.

Fix: after finishing, wait on connection.closed() (bounded by
FILE_FETCH_TIMEOUT) so the link stays up until the fetcher has read
everything and closed the connection itself, which is the signal the
transfer landed.

Wire-compatible (no protocol change), so version stays 0.3.0; both peers
just need the rebuilt binary since either side can be the file server.

Adds tests/file_transfer_loopback.rs: a real two-endpoint serve->fetch
round-trip over FILES_ALPN with a 2 MiB multi-packet blob (deterministic
A/B: 0/20 pass without the fix, 20/20 with it) plus an unknown-id "gone"
case.

molluskandClaude Opus 4.8 f75760b14e Chat file attachments, stage 2: file-transfer network plane
Add the dedicated FILES_ALPN data plane that moves attachment bytes
off-gossip via direct QUIC streams.

- FileRouter (ProtocolHandler on the persistent router, mirroring
  AudioRouter): bound to the active session's Shared on join, cleared on
  leave. On an inbound stream it authenticates the peer via the ALPN
  handshake, gates on live room membership (reuses audio_sender_admitted,
  so a former member cannot pull files), reads exactly one 32-byte
  attachment id (bounded request read), and streams back the matching
  blob from the session serve store — or an empty body for an unknown id.
- Shared gains served_files (id -> bytes), populated by serve_attachment
  and cleared on leave.
- IrohTransport::serve_attachment + fetch_attachment (inherent methods;
  transport is used concretely). fetch dials the sender on FILES_ALPN
  (preferring a known full address), writes the id, and reads bounded by
  the descriptor's declared size, with a 30s connect/read timeout so a
  stalled sender can't hang the fetch.
- Register FILES_ALPN in the router; bind/clear file_router in lock-step
  with audio_router at every join/leave site.

Builds + clippy clean, 349 lib tests pass (plane is runtime I/O,
field-tested in stage 5).

molluskandClaude Opus 4.8 02cb46550e Chat file attachments, stage 1: protocol + data model + pure seams
First slice of in-chat file/photo sharing (dedicated file plane, images
inline + file chips, session-only). This stage adds the wire types and
the pure, unit-tested logic; no transport or UI yet.

- protocol: new FILES_ALPN / FILES_PROTO (peerspeak/files/1) for the
  dedicated file-transfer plane. Bump GOSSIP_PROTO 1->2 + sig domain v2
  (Chat gained an attachment field, so cross-version peers fail fast
  rather than half-work) and Cargo 0.2.0 -> 0.3.0 per VERSIONING.md.
  BREAKING wire change: all peers must run >= 0.3.0.
- new src/files.rs: ChatAttachment descriptor (name/size/kind/id; bytes
  travel off-gossip), AttachmentKind, plus pure seams — sanitize_filename
  (path-traversal/control-char/length-safe), size_within_cap, image
  magic-byte sniffing + defensive limited decode (decode-bomb guard),
  32-byte request parsing, human_size. 13 unit tests.
- GossipMessage::Chat and RoomEvent::ChatMessage carry an optional
  ChatAttachment; send_chat takes Option<ChatAttachment>. Untrusted
  inbound descriptors are filename-sanitized + size-validated on ingest.
  serde(default) keeps the field forward-compatible at the JSON layer;
  +round-trip and pre-v2 back-compat tests.

The attachment id is a random 32-byte handle (rand, already a dep), not
a content hash — the fetch is authenticated + encrypted + member-gated,
so no crypto-hash dep is needed.

349 lib tests pass, clippy clean.

molluskandClaude Opus 4.8 3ec09de87e Adopt versioning standard + migrate to versioned protocol planes (0.2.0)
Establishes VERSIONING.md: SemVer 0.x (MINOR = breaking wire change) for the
release version, and per-plane protocol versions enforced on the wire so
incompatible peers fail fast and legibly instead of via silent decode/signature
errors.

⚠️ BREAKING WIRE CHANGE — all peers must run >= 0.2.0 to interoperate (ALPNs and
gossip subscription topics changed). A pre-0.2.0 peer (e.g. an un-resynced
dopedart) can no longer connect, by design, and now fails at the handshake.

- New src/protocol.rs: single source of truth for AUDIO/FRIENDS/GOSSIP_PROTO,
  the derived ALPNs (peerspeak/audio/1, peerspeak/friends/1), GOSSIP_SIG_DOMAIN,
  and versioned_topic(). Unit tests assert ALPN/domain strings match their
  integer versions (no silent drift) + that topic namespacing is deterministic.
- Unified ALPNs: audio was b"peerspeak-audio" (unversioned, and duplicated in
  iroh_impl.rs + core/mod.rs) -> peerspeak/audio/1 from protocol.rs; friends
  re-exports protocol::FRIENDS_ALPN (was peerspeak/friends/0 -> /1).
- Gossip: subscribe to versioned_topic(ticket.topic_id) so different gossip
  versions never share a swarm; the raw topic_id stays the room identity and
  what signatures bind. GOSSIP_SIG_DOMAIN centralized into protocol.rs.
- Cargo.toml 0.1.0 -> 0.2.0.

316 lib tests / clippy --all-targets clean. VERSIONING.md documents the bump
rules, the "I changed X -> what do I bump" table, and a release checklist.

molluskandClaude Opus 4.8 1adf8a97bb S8 (Pass 2): wire grace-aware audio-membership admission
Closes S8 (High): inbound audio was authenticated by identity (remote_id) but
NOT by room membership, so a former member who knew a current member's endpoint
could reconnect on the audio ALPN and inject into / eavesdrop on the mix while
invisible in the roster. Now audio is admitted only for live gossip-roster
members (the senior+user-resolved GRACE-AWARE policy).

Transport (src/network/iroh_impl.rs):
- New per-session admitted_audio: HashSet<EndpointId> on Shared (internal state,
  no wire/serialization change). Cleared on disconnect_all.
- AudioRouter::accept consults audio_sender_admitted BEFORE ensure_supervisor —
  a non-member never gets a supervisor, sender handle, datagram reader, or
  outbound mix. Brief StdMutex check, released before the await (no RT lock).
- Pure apply_audio_admission_event(roster, peer, event) with AudioAdmissionEvent
  {RosterPresent insert, TransientDropGrace no-op, Remove}. Grace deliberately
  cannot ADD membership — it only preserves an already-admitted peer — so an
  unknown peer can't sneak in via a grace event. +3 lifecycle tests (on top of
  Pass-1's 4 predicate tests).
- admit/keep_for_reconnect_grace/remove/query methods for core to drive.

Core (src/core/mod.rs) — authority is core's VERIFIED gossip-roster events, not
transport connect/disconnect:
- PeerJoined / PeerUpdated: admit_audio_sender before connect_peer.
- PeerConnectionLost: keep_audio_sender_for_reconnect_grace (preserve through the
  existing RECONNECT_GRACE window — no audio cut on transient blips).
- gossip PeerLeft, transport ConnEvent::Left, grace-timer expiry: remove_audio_sender
  before disconnect_peer + jitter removal (removal-before-teardown bounds the
  in-flight-datagram race).
- datagram receiver: audio_sender_admitted gate before any jitter buffer (defense
  in depth against a datagram racing a removal). Mixer stays off the hot path.

Mid-join: a peer who dials audio before we've verified their signed Announce is
dropped (no "pending" admission, which would reintroduce the eavesdrop); their
reconnect loop recovers once the Announce admits them.

tests/transport_loopback.rs: admit both ends before connecting, mirroring the
production room-event order.

313 lib / clippy --all-targets / transport_loopback 4 / reconnect_eviction 6 /
release — all re-run green by the senior. Former-member-rejection + mid-join
recovery are verifiable only in a 2-machine call (senior's to run).

molluskandClaude Opus 4.8 10707152a3 S8 (design-first): pure audio_sender_admitted membership seam (unwired)
Design-first checkpoint for S8 (authorize inbound audio against live room
membership). Codex's design note (in the handoff task-report.md) establishes
the authoritative roster = gossip IrohGossipState.peers, NOT the audio
transport connection list, and recommends mirroring it into an audio-admission
snapshot consulted at AudioRouter::accept + datagram ingest.

This commit lands ONLY the pure decision seam + tests; wiring is deliberately
paused for a senior decision on the reconnect-grace policy (gossip drops a peer
from the roster on transient NeighborDown, but core keeps the audio supervisor
alive for RECONNECT_GRACE — a strict roster-only gate would cut audio on blips).

- audio_sender_admitted(remote, roster) -> bool (pub(crate), #[allow(dead_code)]).
- 4 tests: member admitted, stranger rejected, former member rejected after
  roster removal, mid-join peer rejected until authenticated Announce inserts it.
- No behavior change: accept/datagram/mixer paths untouched. S8 remains OPEN.

310 lib tests / clippy --all-targets / release all green (re-run by senior).

molluskandClaude Opus 4.8 5086e86bd2 Security hardening: log redaction + 5 trust-boundary fixes (S10, T1/T2/T5/T6/T7)
Codex (gpt-5.5) implementer branch, senior-reviewed.

- S10 (High): redact capabilities/chat from logs; create log 0600 + chmod
  existing; rotate at 5 MiB. New short_id/short_bytes_hex/redact_for_log seams.
- T1 (P2): friends-ALPN authorizes (handler(from)) before reading any peer
  bytes; unauthorized conns closed pre-read (DoS relief).
- T2 (P2): per-(author,kind) replay gate on state-changing gossip (Announce/
  Leave) only; Chat bypasses it, preserving the S2 no-monotonic-ts decision.
- T5 (P2): cap inbound Opus datagrams at 4 + MAX_OPUS_PAYLOAD (4000).
- T6 (P2): bind friend-Pong room ticket host to the authenticated responder
  (interpret_pong/probe now thread the remote id) — blocks Join-button
  redirect/phishing. Non-regressive given the W7 P3 restamp design.
- T7 (P3): sanitize_ticket caps/validates PeerState.sharing at gossip ingest
  so invalid offers never render a Watch button.

302 lib tests pass (was 291), clippy --all-targets clean, release builds.
Tests-green only; DoS relief + 2-machine replay/redirect behavior want a

molluskandClaude Opus 4.8 c12d15ed7d feat(w7): recently-joined rooms list with one-click rejoin (P5)
Add a purely-local, most-recent-first recents list so users can hop back
into a room they were just in — meaningful now that rooms carry cosmetic
labels.

- src/recents.rs (new): `Recent {name, ticket, joined_at}`, `push_recent`
  (de-dupes by room `topic_id`, refresh-and-move-to-front, caps at
  RECENTS_MAX=12), `remove_recent`, `relative_time` ("5m ago"). 6 tests.
- PeerSpeakTicket::topic_of — the stable room identity used as the de-dup
  key (host addr + label change between members/sessions; topic doesn't).
- AppConfig.recents (`#[serde(default)]`, back-compat) — local UI state,
  never sent over the wire.
- Recorded on RoomJoined (label via label_of); rendered as a "Recent
  rooms" block in connect_card (each entry → JoinRecent, ✕ → RemoveRecent),
  shown only when non-empty.

Rejoin is best-effort by design: the stored ticket only admits us while
the room is still live and reachable (reliability is P6 discovery + the
member-issued ticket floor, not this list).

263 lib tests green, clippy --all-targets clean. Recents UI
screenshot-verified (seeded config → ages + Untitled-room fallback render).

molluskandClaude Opus 4.8 4227ecc61d feat(w7): cosmetic room labels carried in the ticket (P5)
Rooms can now be named. A "Room name (optional)" field on the home Create card
mints a ticket carrying the label; PeerSpeakTicket gains a #[serde(default)]
`name` field (backward/forward compatible — serde ignores unknown fields and
defaults missing ones, so old/new builds still interoperate, just without
labels). restamp preserves the label so member-issued doors keep it; new
label_of helper reads it. Every member (creator or joiner) sets current_room.name
from the ticket, so presence reports a consistent "in <name>" to friends, and the
room-screen header shows the label under the wordmark. Labels are sanitized via
sanitize_name on both mint and display (untrusted peer-supplied ticket).

CoreCommand::Join gains room_name (used only when creating). +2 ticket tests
(label round-trip through restamp/label_of, pre-label backward-compat). clippy
--all-targets clean, 257 lib tests green.

Pure seam unit-tested + home field screenshot-verified; the in-room header label
and friend-side "in HangOut" presence display need a live/2-machine confirm.

molluskandClaude Opus 4.8 fdab4e03a2 refactor(net): persistent endpoint/gossip/router (W7 B1)
The friends-only presence listener (W7) must answer pings while the app is
open, whether or not we're in a call — but a node id has exactly one live
endpoint instance (proven by the dual-endpoint spike: two endpoints sharing a
SecretKey collide, all inbound connections land on one and the other's ALPN
fails the QUIC handshake). So the listener can't get its own endpoint; the
whole app must share one persistent endpoint. Today the core rebuilds the
endpoint+gossip+router on every Join and tears them down on leave, so there's
nothing alive between calls.

B1 hoists those durable pieces to the app lifetime (no new behavior):

- New persistent `NetStack` (endpoint + gossip + Router) built once at startup
  under the RelayNoDiscovery default (relay reachability, no DNS beacon);
  `online()` is backgrounded so launch isn't blocked.
- New persistent `AudioRouter` (src/network/iroh_impl.rs) replaces the
  per-session `AudioProtocol`: it's registered once on the single Router and
  delegates each inbound audio connection to whatever session `Shared` is bound
  (`bind` on join, `clear` on leave), dropping links when idle. `IrohTransport::
  new` now returns just `Self`.
- Join reuses `net.endpoint`/`net.gossip` and only subscribes its gossip topic +
  binds the audio router; Leave clears the router but keeps the endpoint up.
- `SetNetworkMode`/`RegenerateIdentity` rebuild the stack immediately when idle,
  else defer to the next Leave/Join (preserves "applies on next join"), and the
  existing session is always torn down before any rebuild closes the endpoint.

Tests/loopback updated for the new transport API. 256 lib + 6 reconnect + 4
loopback + 2 ignored real-endpoint tests green, clippy --all-targets clean,
release builds. NOT yet 2-machine field-verified — that regression is the gate
before this merges to main.

molluskandClaude Opus 4.8 c90dcf71ef feat(tickets): member-issued tickets so rooms outlive their creator (W7 P3)
The ticket a member sees/copies for sharing is now stamped with THEIR OWN
live address + the room's topic, not the (possibly someone else's) ticket they
joined with. So every member — not just the creator — hands out a working door
that bootstraps newcomers off themselves; a room stays reachable as long as
anyone inside can share a ticket, even after the creator leaves.

Pure seam PeerSpeakTicket::restamp(ticket_str, my_addr): re-parse, swap
host_addr to mine, keep topic_id; no-op for an unparseable string or when the
addr is already mine. The core re-stamps only the DISPLAY copy sent in
RoomJoined; the join/bootstrap ticket_str and the A8 retain logic are
untouched, so this is non-breaking (same wire format, different addr).

+3 unit tests (swaps addr/keeps topic, idempotent for same addr, passes
through unparseable). 248 lib tests green, clippy clean, release builds.
Tests-green; the end-to-end 'creator leaves, joiner's ticket still works'
behaviour wants a 2-machine field test. Multi-bootstrap (Vec) + ticket
encoding tightening deferred (both breaking wire changes — want daylight).

molluskandClaude Opus 4.8 f029a30ea7 feat(avatars): custom image upload — W4 Phase 3
Completes W4: users can upload a custom avatar image.

- `Avatar::Custom(String)` carries a base64 PNG. `process_upload` decodes an
  arbitrary png/jpeg, downscales so the longest side is 128px (aspect kept),
  re-encodes PNG, base64s, and rejects anything over a hard cap.
- Settings "Avatar" gains an "Upload image…" button (native picker via rfd's
  xdg-portal backend, off-thread through Task::perform) and shows the current
  custom avatar as a selected tile.
- Untrusted peer avatars are validated at gossip ingest (`sanitize_incoming`):
  a custom image must be within the byte cap and decode as a PNG within bounds
  (image-crate decode limits guard against decompression bombs) or it's
  downgraded to a monogram.
- Raised the gossip max message size to 64 KB so a capped custom avatar fits
  inline on the presence plane (all peers already need a matching build).
- Deps: image (png/jpeg only), rfd (xdg-portal, no GTK); only `rfd`+`pollster`
  are actually new in the lockfile (rest were already transitive). cargo audit
  clean (0 vulns; the 2 unmaintained warnings are pre-existing S7).
- `Controller::send` now returns bool (was a Result carrying the now-larger
  CoreCommand by value, which tripped result_large_err).
- +5 avatar unit tests (upload resize/round-trip, reject non-image, ingest
  accept/reject). 227 lib tests green, clippy clean.

Manual check: Settings → Avatar → Upload; confirm the picker opens and the
image shows for you and (after redeploy) for a peer.

molluskandClaude Opus 4.8 3007002b1b feat(avatars): 6 selectable preset avatars over presence — W4 Phase 2
Adds bundled preset avatars on top of the monogram foundation.

- New `Avatar` enum (Monogram | Preset(u8)) in the avatar module, serde-encoded;
  6 preset PNGs embedded via include_bytes! (placeholder art in assets/avatars/
  — swap for real designs later). +3 unit tests.
- `PeerState` gains `avatar` (rides the gossip presence plane like `sharing`);
  `AppConfig` gains `avatar` (persisted). Avatar choice flows app → core (Join +
  new SetAvatar command) → every self-state announce, so it reaches the room incl.
  late joiners, and changing it mid-call re-announces live.
- Settings "Avatar" section: monogram + 6 preset tiles, applied live + persisted.
- Rendering: `avatar_view` draws the chosen preset image (iced `image` feature,
  now enabled) else the monogram, in the self card, peer rows, and chat (chat
  looks up the sender's avatar from presence by id).

⚠️ BREAKING gossip wire change: presence Announce is signed (S2) and the
signature is recomputed by re-serializing the parsed struct, so a new PeerState
field means old and new builds can't verify each other's presence — ALL peers
must run a build >= this one (same as the S2 change). Redeploy dopedart before
2-machine testing.

Build + clippy clean, 222 lib + integration tests green.

molluskandClaude Opus 4.8 7c8f0114f7 fix(net): room creator can rejoin a room they left (A8)
The gossip bootstrap list was derived solely from the ticket: a client
dialed the host, but "we are the host" produced an EMPTY list. So when the
room CREATOR rejoined their own room (their ticket names themselves as host)
they dialed nobody and never re-entered the swarm — the remaining peer stayed
stuck until it too left and rejoined. (First 2-human field test, 2026-06-14;
user-confirmed call-breaking, P1.)

Fix: retain the peers seen in the current room across leave (core
`known_peers`, updated by the event task; reset only when the joined ticket
changes) and pass them to `RoomState::join` as extra bootstrap targets. The
new pure `compute_bootstrap` seam unions the ticket host + retained peers,
drops self, and de-dups; address resolution rides the persistent lookup.

- `RoomState::join` gains `extra_bootstrap: Vec<EndpointAddr>` (test_net
  callers pass vec![]).
- +4 unit tests on `compute_bootstrap`, incl. the host-rejoin regression case.

Tests-green (208 lib + 6 + 4 integration), clippy clean. NOT yet 2-machine
field-verified — needs a live host leave→rejoin call.

molluskandClaude Opus 4.8 2b52a48efe fix(security): authenticate gossip payloads (S2 — sign + verify, replay-bound)
The gossip `author` field was self-asserted, so an in-room member could forge
it to impersonate (chat), force-evict (Leave), or poison presence + the address
book (Announce). Now every GossipPayload is signed with the node's ed25519
secret key and verified on receipt; a forged author can't validate because the
attacker lacks the victim's key.

Done as the complete fix (forgery + replay):
- GossipPayload gains `ts` (sender-stamped) + `sig` (iroh::Signature, serde-64B);
  Debug is hand-written since Signature has none.
- Signature covers domain tag + room topic_id + author + ts + msg
  (`signable_bytes`): topic binding blocks cross-room replay, ts + a 2-min
  freshness window block temporal replay (within-window replays are byte-
  identical and de-duped by the swarm), author binding makes spoofing fail.
- New pure seams `sign_gossip` / `verify_gossip` (+ `GossipReject`); all four
  outgoing broadcasts sign, the receive loop verifies-then-trusts (drops
  unauthenticated/stale before any peer-map / event / address-book action).
- IrohGossipState now holds the node SecretKey + active topic bytes; callers
  (core, test_net) updated.

NOTE: breaking gossip wire change — all peers must run this build (the staged
friend release + dopedart need rebuild). Node identity is ephemeral, so no
migration concern beyond rebuild.

+5 unit tests (genuine accept; forged author, tampered msg, cross-room, stale/
future all rejected). 163 lib tests (was 158), clippy --all-targets clean.

molluskandClaude Opus 4.8 fe627166d5 fix(security): close S3 (arg-injection), S4 (presence-name), S1 (panic-slice)
Three findings from the first security pass:

- S3 (Medium): the peer-supplied screen-share ticket was passed to pixelpass
  as the first positional CLI arg with no end-of-options guard, so a ticket
  starting with `-`/`--` could be reinterpreted as a flag (argument injection).
  New pure `viewer_args()` puts flags first, then a `--` guard, then the ticket
  positionally; spawn_viewer uses it. +2 tests.

- S4 (Medium): peer presence display-names (gossip `Announce`, untrusted and
  spoofable) were rendered unsanitized/unbounded, unlike the chat path. New
  `sanitize::sanitize_name` strips bidi/zero-width format chars + control chars,
  collapses whitespace, and caps at 48 chars; applied at the gossip ingest point
  so every consumer gets a safe value. +4 tests.

- S1 (Low): `&id[..8]` byte-slices could panic on a short/non-ASCII id. New
  panic-free `short_id()` (char-based take) replaces both slices. +1 test.

158 lib tests (was 151), clippy --all-targets clean.

molluskandClaude Opus 4.8 d9e544607a feat: screen sharing via pixelpass (Discord-style, presence-borne ticket)
Surface pixelpass screen-sharing from inside a peerspeak room. peerspeak owns
voice, pixelpass owns pixels — they're never Cargo deps of each other; the
contract is pixelpass's CLI flags + its `--output json` stdout stream.

Modelled on Discord: multiple simultaneous sharers, a 🔴 Live badge + 👁 Watch
on each sharing peer's card, and in-progress shares visible to late joiners.

- New `src/screenshare` module: pure `parse_pixelpass_event` seam + `pixelpass_path`
  discovery (13 unit tests), async `spawn_host` (→ ticket) and `spawn_viewer`
  (→ parse connected{url} → open mpv, vlc fallback). No new deps.
- Sharing rides presence: `PeerState.sharing: Option<ticket>` (serde-defaulted),
  so the existing gossip re-announce delivers the offer to late joiners for free
  and a PeerUpdated fires on start/stop — no separate gossip message needed.
- core: Start/Stop/ViewShare commands; host + viewer children tracked in the
  session, killed on stop/leave (kill_on_drop backstop). Viewer limit left to
  pixelpass's bandwidth-measured cap.
- UI: Share/Stop button (graceful "needs pixelpass" disabled state), Live badge
  + Watch on peer cards, Sharing badge on the self card. Verified by screenshot.
- config: optional `pixelpass_path` override (hand-editable).

Tests-green; the 2-machine gossip/remote path is not yet field-verified.

molluskandClaude Opus 4.8 a6aca73c67 feat: in-room text chat over the gossip plane
Add room text chat riding the existing iroh-gossip topic (same layer as the
presence roster). New GossipMessage::Chat { name, text, ts }; the gossip loop
forwards it as RoomEvent::ChatMessage, core relays it to the UI as
UiEvent::ChatMessage, and RoomState::send_chat broadcasts an authored line
(display name from self-state, ms timestamp). CoreCommand::SendChat sends; our
own author is suppressed by the existing self-echo guard, so the UI echoes our
sent line locally instead.

UI: a full-width chat dock along the bottom of the room (the chosen layout) —
bottom-anchored scrollback with per-sender name colouring (green = you), an
input with Enter-to-send + a Send button, history capped at 300 lines. The room
window default grows to 900x760 so the dock doesn't squeeze the controls column.

molluskandClaude Opus 4.8 8f1ecb2a5e test(network): unit tests for ticket codec + gossip wire types
Add #[cfg(test)] coverage for the join-link codec and gossip wire format:
PeerSpeakTicket Display/FromStr round-trip and — the real gap —
malformed-input rejection (empty / non-base64 / valid-base64-non-JSON all
return NetError::InvalidTicket, never panic, since users paste untrusted
text here); PeerState serde round-trip; and GossipMessage::Leave /
Announce + GossipPayload round-trips. Tests-only; no production change.

Implemented by Gemini (junior implementer), reviewed and verified by senior
(cargo build + clippy --all-targets + cargo test all green).

molluskandClaude Opus 4.8 ffe5b43d8d fix: signal graceful leave at the transport so a disconnect doesn't show "reconnecting"
Field-testing the reconnect fix surfaced a follow-on bug: clicking Disconnect
(or quitting) showed the peer as yellow "Reconnecting" on the other end instead
of leaving cleanly. Logs showed the remote saw NeighborDown first and the gossip
`Leave` arrived ~15s later (broadcast then router torn down ~450ms after, so
NeighborDown — now meaning "reconnecting" — beats the slow, swarm-routed Leave).

Fix: make graceful leave a prompt, reliable TRANSPORT signal instead of relying
on gossip. On leave/quit, IrohTransport::leave() explicitly closes each live
connection with a distinguished goodbye code (GOODBYE_CODE) and aborts all
supervisors (so none linger redialing the about-to-close endpoint). The remote's
supervisor inspects the close reason: an application close with our goodbye code
=> emit the new ConnEvent::Left (evict now); a timeout/reset/other code =>
transient drop, reconnect as before. core handles ConnEvent::Left exactly like a
PeerLeft (cancel grace timer, disconnect, drop jitter, UI remove). ActiveSession
now holds the transport and calls leave() before shutting the router down.

Tracks the live connection per peer in Shared.live_conns (inserted on link up,
removed on drop) so leave() can close them. The gossip Leave path stays as a
harmless backup.

New test dialer_reports_left_on_graceful_close: a close with the goodbye code
reports Left and does NOT reconnect (mirror of the code-0 transient-drop test).
clippy clean, 4 transport tests pass. NOT yet field-verified.

molluskandClaude Opus 4.8 be818467dd fix: keep reconnecting across a long outage instead of evicting on NeighborDown
Field test of the long-outage path failed: ~31s into a Wi-Fi drop the peer
vanished with no "Reconnecting..." indicator and never came back. Logs showed
the chain `Gossip NeighborDown -> Removed peer -> Transport: stopped
supervising peer`.

Root cause: a transient gossip NeighborDown was routed to RoomEvent::PeerLeft,
same as a graceful leave, so core called disconnect_peer -> supervisor.abort().
That aborted the very reconnect supervisor that was meant to redial -- before
its own reconnect loop (which re-emits Connecting and re-dials the retained
09acefd address with backoff) ever ran. The supervisor + retained-address fix
were effectively dead code in the field, which is also why the loopback tests
(they drive the supervisor directly) never caught it.

Fix: decouple a transient drop from a graceful leave.
- gossip.rs: NeighborDown now emits the new RoomEvent::PeerConnectionLost
  instead of PeerLeft. A graceful GossipMessage::Leave still emits PeerLeft.
- core: on PeerConnectionLost, do NOT disconnect the peer. Keep its supervisor
  alive (it redials the retained address and drives the yellow indicator) and
  arm a per-peer reconnect grace timer (RECONNECT_GRACE = 45s, comfortably past
  the ~30s QUIC idle timeout). The peer is evicted only if the link hasn't
  recovered when the timer fires. A gossip rejoin (PeerJoined/PeerUpdated) or a
  transport reconnect (ConnEvent::Connected) cancels the timer first; session
  shutdown aborts all pending timers so none fire a stray eviction.

Builds clean, clippy clean, 3 transport tests pass. NOT yet field-verified --
re-test the long-outage path on a real call.

molluskandClaude Opus 4.8 09acefd2b3 fix: retain peer address so a transient gossip Leave can't strand the dialer
The dialer-side supervisor dialed peers by bare EndpointId, forcing iroh to
resolve the address through the gossip-fed MemoryLookup. A transient drop that
also triggered a gossip Leave/NeighborDown purged the peer from that lookup, so
the supervisor redialed forever with "no address" (observed in the 2026-05-30
field test: ~4.5 min of "No address lookup configured; retrying in 5s").

The transport now retains each peer's full EndpointAddr (relay + direct addrs),
refreshed on join and on every re-announce (so a rejoin on a new address updates
the dial target), and the dialer dials that retained address directly — which
bypasses the lookup entirely. connect_peer now takes an EndpointAddr; core hands
over state.addr on PeerJoined and PeerUpdated.

New regression test dials and reconnects with the dialer's lookup deliberately
empty and the relay disabled, so only the retained address can carry the dial:
it passes with the fix and times out under the old bare-id behavior.

molluskandClaude Opus 4.8 ccf2bff87c feat: reconnect on transient link loss with per-peer supervisors
Audio links now survive a dropped QUIC connection instead of silently
dying until the peer leaves and rejoins the room.

Transport: each peer is owned by a single supervisor task running a
connect → run → reconnect loop. The deterministic-initiator rule (lower
id dials, higher accepts) holds on every reconnect, so one shared
connection re-forms each time; the dialer redials with capped backoff
and the acceptor awaits the inbound link, switching to a replacement
immediately if one arrives before its own close fires. Inbound
connections are routed to the supervisor via a per-peer channel.

Fixes a latent bug from the prior design: aborting a peer's tasks left
the detached send/read loops running, holding Connection clones so the
link never actually closed. The loops now live in abort-on-drop guards
scoped to the supervisor, so cancelling it releases the connection.

UX: a new ConnEvent stream surfaces per-peer link state to the UI, which
shows "Connecting…"/"Reconnecting…" with a yellow indicator and border
while a peer's audio link is down, returning to normal when it recovers.

Tests: the loopback test now runs through the supervisor path, plus a
new test drives a real drop (explicit close of a controlled peer
endpoint) and asserts the dialer re-dials the stable address and audio
resumes over the rebuilt connection.

molluskandClaude Opus 4.8 875e6e124c feat: redesign audio networking for real-network resilience
Replaces the fire-and-forget datagram path with sequenced packets, a
per-peer jitter buffer, and persistent per-peer send tasks. Together these
fix three intertwined weaknesses that only showed up off localhost.

Packet format: every audio frame now carries a 4-byte little-endian
sequence number header ([seq][opus payload]), the basis for reordering and
loss detection.

Jitter buffer (core/jitter.rs): incoming packets are reordered by sequence
behind a fixed ~60ms playout delay. Missing sequences with later packets
already buffered are concealed via Opus PLC (decode(None)) -- a path the
decoder supported but nothing ever invoked. Underruns go idle and re-buffer
rather than concealing indefinitely. Covered by unit tests using real
encoded frames (reorder, gap-conceal, prime, late-drop).

Transport (network/iroh_impl.rs): each peer gets one long-lived send task
fed by a shallow bounded channel (drop-oldest on backpressure), instead of
spawning a throwaway task per peer per 20ms frame. Connections are now
established reactively on peer-join and torn down on peer-leave; the
lexicographically-lower EndpointId dials so a full-mesh pair forms exactly
one shared bidirectional connection instead of two racing ones. This also
removes the previous lock-held-across-connect().await serialization.

Opus decoder: PLC output is now sized to one 20ms frame, so concealment
synthesizes 20ms instead of a 120ms burst from the oversized max buffer.

Known follow-up (Tier 2): no reconnect on transient connection loss; a
send error currently retires the peer until they rejoin.
