- 'matrix_harness send "text"' — one-shot unprompted messaging to the
pinned room (agent announcements/alerts)
- backlog no longer re-forwards read messages: last homeserver
origin_server_ts persisted to /tmp/matrix-harness.state, advanced on
every processed event; events at/below it are skipped
- 30-min staleness window retained as outer bound
- sync(): std.json walk of rooms.join.*.timeline (old string-window scraper
misattributed senders across events); Event gains ts
- startup backlog: peer messages from last 30min forwarded to agent as
context (reply suppressed); failures logged, never fatal (systemd
Restart=on-failure would otherwise re-forward every 3s)
- messages to agent prefixed [matrix HH:MMZ] with UTC event timestamp
- sendText: jsonEscape covers control chars (\u00XX), markdown -> HTML
formatted_body (bold/italic/code/fences) for Element rendering
- no startup banner in room; harness now runs as systemd user service
matrix-harness (unit + .matrix-env, untracked)
Reuses the fixed room when MATRIX_ROOM is set; only creates a fresh DM
when unset. All replies go to the pinned room.

- src/matrix.zig: minimal Matrix client (conduwuit @ matrix.chaosmith.systems)
via curl subprocess transport (native TLS swap later): login, createRoom
(trusted_private_chat, unencrypted — no olm), sendText, sync polling with
window-scan event extraction reusing letta.jsonStr
- src/matrix_harness.zig: standalone entrypoint (independent of tray daemon):
login -> DM with peer -> sync loop -> peer messages routed through letta
CLI (chaos-prime) -> replies sent back to the room
- build.zig: second exe matrix_harness; use_llvm fix promoted into build.zig
for both executables (native lld vs GCC16 .sframe relocations)
- calling/Element Call (livekit SFU already deployed on ass-host) layers on
top of this harness next

Qt rich text collapses raw newlines to whitespace; convert before render.

- tray submenus: Agent (from letta agents list, radio-style) and
Conversation (from local backend storage, CLI has no listing surface)
- conversation entries show preview: summary or last-message text
- conversation menu refreshes on aboutToShow (KDE DBus menu syncs a
step behind eager mutation)
- CLI rule honored: --agent only with --conversation default; named
conversations imply the agent
- plain-text fallback parsing for non-stream-json output
- empty-reply debug: raw stream tail dump
- prefs: ~/.local/inferon/prefs.json, saved on pick, loaded at startup,
HOME-resolved paths (std.c.getenv), owned buffers (no alias double-free)
- leak fixes: agent name fallback, quit-path drains for menu entries

- playback.zig: sentence queue + playback thread — agent reply chunks are
split on sentence boundaries and each sentence is synthesized+played as it
completes, so voice starts after the first sentence, not after the reply
- melo_server.py v2: WAV written to /dev/shm, raw s16le PCM + sample rate
streamed over stdout (WAV n rate header + bytes), file deleted immediately;
melo stdout chatter rerouted to stderr to keep the protocol clean
- melo.zig: speakRaw returns in-memory PCM; pw-play fed via stdin pipe
(no on-disk TTS files at all)
- whisper: --language auto
- fix: double-close of pw-play stdin panicked Threaded Io in debug
- fix: quit-path frees for transcript cache, bubble lists, sentence queue,
reply buffer (debug allocator leak panic)

- processUtterance runs on a detached std.Thread; Qt event loop stays
responsive during whisper/letta/melo (icon repaints, menu works)
- setState marshals to main thread via threading.async with thread-id check
- rapid double-click race guarded: state claimed before spawn
- icon: QPainter-drawn antialiased circle (dark rim, transparent bg) —
bare pixmap.fill rendered blank on the KDE SNI host
- new qt libs: qbrush, qpainter, qrect, qt6zigthreading

- melo_server.py subprocess (MeloTTS v3 EN-Newest, speed 1.3): line protocol
stdin->stdout, model loaded once, warmup before READY
- src/melo.zig: lifecycle ownership (spawn/kill with inferon), line protocol
client, reply sanitizer (newlines/markdown stripped before synthesis)
- SIGINT/SIGTERM handlers: async-signal-safe kill of whisper/melo/recorder,
default disposition restored + re-raise for truthful exit status
- processUtterance: transcribe->infer->speak chains automatically after
stop-click; mid-pipeline clicks are no-ops; back to idle after reply
- temp cleanup: recording WAV deleted after transcription, TTS WAV after
playback
- whisper: pid() export for signal handler
