Subject: [PATCH 01/93] feat: add voice mode with push-to-talk and TTS output
 for CLI

Implements Issue #314 Phase 2 & 3:
- /voice command to toggle voice mode (on/off/tts/status)
- Ctrl+Space push-to-talk recording via sounddevice
- Whisper STT transcription via existing transcription_tools
- Optional TTS response playback via existing tts_tool
- Visual indicators in prompt (recording/transcribing/voice)
- 21 unit tests, all mocked (no real mic/API)
- Optional deps: sounddevice, numpy (pip install hermes-agent[voice])

Subject: [PATCH 02/93] feat: add Groq STT support and fix voice mode
 keybinding

- Add multi-provider STT support (OpenAI > Groq fallback) in transcription_tools
- Auto-correct model selection when provider doesn't support the configured model
- Change voice record key from Ctrl+Space to Ctrl+R (macOS compatibility)
- Fix duplicate transcript echo in voice pipeline
- Add GROQ_API_KEY to .env.example

 Transcription Tools Module
 
-Provides speech-to-text transcription with two providers:
-
-  - **local** (default, free) — faster-whisper running locally, no API key needed.
-    Auto-downloads the model (~150 MB for ``base``) on first use.
-  - **openai** — OpenAI Whisper API, requires ``VOICE_TOOLS_OPENAI_KEY``.
+Provides speech-to-text transcription using OpenAI-compatible Whisper APIs.
+Supports multiple providers with automatic fallback:
+  1. OpenAI (VOICE_TOOLS_OPENAI_KEY) -- paid
+  2. Groq  (GROQ_API_KEY)           -- free tier available

Subject: [PATCH 03/93] fix: voice mode TTS playback and keybinding issues

- Change record key from c-@ to c-r (Ctrl+R) for macOS compatibility
- Add missing tempfile and time imports that caused silent TTS crash
- Use MP3 output for CLI TTS playback (afplay doesn't handle OGG well)
- Strip markdown formatting from text before sending to TTS
- Remove duplicate transcript echo in voice pipeline

Subject: [PATCH 05/93] fix: improve voice mode robustness and add integration
 tests

- Show TTS errors to user instead of silently logging
- Improve markdown stripping: code blocks, URLs, links, horizontal rules
- Fix stripping order: process markdown links before removing URLs
- Add threading.Lock for voice state variables (cross-thread safety)
- Add 14 CLI integration tests (markdown stripping, command parsing, thread safety)
- Total: 47 voice-related tests

Subject: [PATCH 06/93] fix: isolate GROQ_API_KEY in test_missing_stt_key test

The test was failing because GROQ_API_KEY leaked from the environment.
Now both VOICE_TOOLS_OPENAI_KEY and GROQ_API_KEY are removed to
properly test the "no STT key" scenario.

Subject: [PATCH 07/93] feat: add Phase 4 low-latency features for voice mode

- Audio cues: beep on record start (880Hz), double beep on stop (660Hz)
- Silence detection: auto-stop recording after 3s of silence (RMS-based)
- Continuous mode: auto-restart recording after agent responds
  - Ctrl+R starts continuous mode, Ctrl+R during recording exits it
  - Waits for TTS to finish before restarting to avoid recording speaker
- Tests: 7 new tests for beep generation and silence detection

Subject: [PATCH 08/93] feat: add silence filter, hallucination guard, and
 continuous mode control

- Skip silent recordings before STT call (RMS check in AudioRecorder.stop)
- Filter known Whisper hallucinations ("Thank you.", "Bye." etc.)
- Continuous mode: Ctrl+R starts loop, Ctrl+R during recording exits it
- Wait for TTS to finish before auto-restart to avoid recording speaker
- Silence timeout increased to 3s for natural pauses
- Tests: hallucination filter, silent recording skip, real speech passthrough

Subject: [PATCH 09/93] fix: fix silence detection bugs and add Phase 4 voice
 mode features

Fix 3 critical bugs in silence detection:
- Micro-pause tolerance now tracks dip duration (not time since speech start)
- Peak RMS check in stop() prevents discarding recordings with real speech
- Reduced min_speech_duration from 0.5s to 0.3s for reliable speech confirmation

Phase 4 features: configurable silence params, visual audio level indicator,
voice system prompt, tool call audio cues, TTS interrupt, continuous mode
auto-restart, interruptable playback via Popen tracking.

Subject: [PATCH 10/93] fix: fix voice recording stuck in continuous mode

- Track submitted state locally instead of using racy qsize() check
- Allow Ctrl+R to stop recording even while agent is running
- Add double-start guard to prevent concurrent recording attempts

Subject: [PATCH 11/93] feat: add streaming sentence-by-sentence TTS via
 ElevenLabs

Stream audio to speaker as the agent generates tokens instead of
waiting for the full response. First sentence plays within ~1-2s
of agent starting to respond.

- run_agent: add stream_callback to run_conversation/chat, streaming
  path in _interruptible_api_call accumulates chunks into mock
  ChatCompletion while forwarding content deltas to callback
- tts_tool: add stream_tts_to_speaker() with sentence buffering,
  think block filtering, markdown stripping, ElevenLabs pcm_24000
  streaming to sounddevice OutputStream
- cli: wire up streaming TTS pipeline in chat(), detect elevenlabs
  provider + sounddevice availability, skip batch TTS when streaming
  is active, signal stop on interrupt

Falls back to batch TTS for Edge/OpenAI providers or when
elevenlabs/sounddevice are not available. Zero impact on non-voice
mode (callback defaults to None).

Subject: [PATCH 12/93] fix: catch OSError on sounddevice import for CI without
 PortAudio

sounddevice raises OSError (not ImportError) when the PortAudio C
library is missing. This broke test collection on CI runners that
have the Python package installed but lack the native library.

Subject: [PATCH 14/93] feat: sync text display with TTS audio playback

Move screen output from stream_callback to display_callback called by
TTS consumer thread. Text now appears sentence-by-sentence in sync with
audio instead of streaming ahead at LLM speed. Removes quiet_mode hack.

Subject: [PATCH 15/93] fix: voice mode race conditions, temp file leak, think
 tag parsing

- Atomic check-and-set for _voice_recording flag with _voice_lock
- Guard _voice_stop_and_transcribe against concurrent invocation
- Remove premature flag clearing from Ctrl+R handler
- Clean up temp WAV files in finally block (_play_via_tempfile)
- Use buffer-level regex for <think> block filtering (handles chunked tags)
- Prevent /voice on prompt accumulation on repeated calls
- Include Groq in STT key error message

Subject: [PATCH 16/93] fix: suppress verbose logs during streaming TTS,
 improve hallucination filter, stop continuous mode on errors

- Add _vprint() helper to suppress log output when stream_callback is active
- Expand Whisper hallucination filter with multi-language phrases and regex pattern for repetitive text
- Stop continuous voice mode when agent returns a failed result (e.g. 429 rate limit)

Subject: [PATCH 18/93] fix: streaming tool call parsing, error handling, and
 fake HA state mutation

- Fix Gemini streaming tool call merge bug: multiple tool calls with same
  index but different IDs are now parsed as separate calls instead of
  concatenating names (e.g. ha_call_serviceha_call_service)
- Handle partial results in voice mode: show error and stop continuous
  mode when agent returns partial/failed results with empty response
- Fix error display during streaming TTS: error messages are shown in
  full response box even when streaming box was already opened
- Add duplicate sentence filter in TTS: skip near-duplicate sentences
  from LLM repetition
- Fix fake HA server state mutation: turn_on/turn_off/set_temperature
  correctly update entity states; temperature sensor simulates change
  when thermostat is adjusted

Subject: [PATCH 20/93] fix: address voice mode review feedback

1. Fully lazy imports: sounddevice, numpy, elevenlabs, edge_tts, and
   openai are never imported at module level. Each is imported only when
   the feature is explicitly activated, preventing crashes in headless
   environments (SSH, Docker, WSL, no PortAudio).

2. No core agent loop changes: streaming TTS path extracted from
   _interruptible_api_call() into separate _streaming_api_call() method.
   The original method is restored to its upstream form.

3. Configurable key binding: push-to-talk key changed from Ctrl+R
   (conflicts with readline reverse-search) to Ctrl+B by default.
   Configurable via voice.push_to_talk_key in config.yaml.

4. Environment detection: new detect_audio_environment() function checks
   for SSH, Docker, WSL, and missing audio devices before enabling voice
   mode. Auto-disables with clear warnings in incompatible environments.

5. Graceful degradation: every audio touchpoint (sd.play, sd.InputStream,
   sd.OutputStream) wrapped in try/except with ImportError/OSError
   handling. Failures produce warnings, not crashes.

Subject: [PATCH 22/93] fix: wrap sd.InputStream in try-except and fix config
 key name

- AudioRecorder.start() now catches InputStream errors gracefully
  with a clear error message about microphone availability
- Fix config key mismatch: cli.py was reading "push_to_talk_key"
  but config.py defines "record_key" -- now consistent
- Add format conversion from config format ("ctrl+b") to
  prompt_toolkit format ("c-b")

Subject: [PATCH 23/93] fix: address voice mode PR review (streaming TTS,
 prompt cache, _vprint)

Bug A: Replace stale _HAS_ELEVENLABS/_HAS_AUDIO boolean imports with
lazy import function calls (_import_elevenlabs, _import_sounddevice).
The old constants no longer exist in tts_tool -- the try/except
silently swallowed the ImportError, leaving streaming TTS dead.

Bug B: Use user message prefix instead of modifying system prompt for
voice mode instruction. Changing ephemeral_system_prompt mid-session
invalidates the prompt cache. Now the concise-response hint is
prepended to the user_message passed to run_conversation while
conversation_history keeps the original text.

Minor: Add force parameter to _vprint so critical error messages
(max retries, non-retryable errors, API failures) are always shown
even during streaming TTS playback.

Tests: 15 new tests in test_voice_cli_integration.py covering all
three fixes -- lazy import activation, message prefix behavior,
history cleanliness, system prompt stability, and AST verification
that all critical _vprint calls use force=True.

Subject: [PATCH 24/93] fix: resolve 6 voice mode bugs found during audit

- edge_tts NameError: _generate_edge_tts now calls _import_edge_tts()
  instead of referencing bare module name (tts_tool.py)
- TTS thread leak: chat() finally block sends sentinel to text_queue,
  sets stop_event, and joins tts_thread on exception paths (cli.py)
- output_stream leak: moved close() into finally block so audio device
  is released even on exception (tts_tool.py)
- Ctrl+C continuous mode: cancel handler now resets _voice_continuous
  to prevent auto-restart after user cancels recording (cli.py)
- _disable_voice_mode: now calls stop_playback() and sets
  _voice_tts_done so TTS stops when voice mode is turned off (cli.py)
- _show_voice_status: reads record key from config instead of
  hardcoding Ctrl+B (cli.py)

Subject: [PATCH 25/93] fix: remove browser_tool signal handlers that cause
 voice mode deadlock

browser_tool.py registered SIGINT/SIGTERM handlers that called sys.exit()
at module import time. When a signal arrived during a lock acquisition
(e.g. AudioRecorder._lock in voice mode), SystemExit was raised inside
prompt_toolkit's async event loop, corrupting coroutine state and making
the process unkillable (required SIGKILL).

atexit handler already ensures browser sessions are cleaned up on any
normal exit path, so the signal handlers were redundant and harmful.

Subject: [PATCH 27/93] fix: prevent Ctrl+B key handler from blocking
 prompt_toolkit event loop

The handle_voice_record key binding runs in prompt_toolkit's event-loop
thread. When silence auto-stopped recording, _voice_recording was False
but recorder.stop() still held AudioRecorder._lock. A concurrent Ctrl+B
press entered the START path and blocked on that lock, freezing all
keyboard input.

Three changes:
- Set _voice_processing atomically with _voice_recording=False in
  _voice_stop_and_transcribe to close the race window
- Add _voice_processing guard in the START path to prevent starting
  while stop/transcribe is still running
- Dispatch _voice_start_recording to a daemon thread so play_beep
  (sd.wait) and AudioRecorder.start (lock acquire) never block the
  event loop

Subject: [PATCH 28/93] fix: move process_loop voice restart to daemon thread,
 use _cprint consistently
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- process_loop's continuous mode restart called _voice_start_recording()
  directly, blocking the loop if play_beep/sd.wait hangs — queued user
  input would stall silently. Dispatch to daemon thread like Ctrl+B handler.
- Replace print() with _cprint() in _handle_voice_command for consistency
  with the rest of the voice mode code.

Subject: [PATCH 29/93] fix: add timeout to play_beep sd.wait and wrap silence
 callback in try-except
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Replace sd.wait() with a poll loop + sd.stop() in play_beep().
  sd.wait() calls Event.wait() without timeout — hangs forever if the
  audio device stalls. Poll with a 2s ceiling and force-stop instead.
- Wrap _on_silence callback in try-except so exceptions are logged
  instead of silently lost in the daemon thread. Prevents recording
  state from becoming inconsistent on unexpected errors.

Subject: [PATCH 30/93] fix: add STT timeout, move finally restart to thread,
 guard exit on recording
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Set OpenAI client timeout=30s in transcribe_audio() — default 600s
  blocks _voice_processing for 10 min if Groq/OpenAI stalls
- Move _voice_start_recording in _voice_stop_and_transcribe finally
  block to a daemon thread (same pattern as Ctrl+B handler and
  process_loop)
- Add _should_exit guard at top of _voice_start_recording so all 4
  call sites respect shutdown without individual checks

Subject: [PATCH 31/93] fix: disable STT retries and stop continuous mode after
 3 silent cycles

- Set max_retries=0 on the STT OpenAI client. The SDK default (2) honors
  Groq's retry-after header (often 53s), blocking the thread for up to
  ~106s on rate limits. Voice STT should fail fast, not retry silently.
- Stop continuous recording mode after 3 consecutive no-speech cycles to
  prevent infinite restart loops when nobody is talking.

Subject: [PATCH 32/93] fix: add max recording timeout to prevent infinite wait
 in quiet environments

AudioRecorder now auto-stops after 15 seconds if no speech is detected
(_has_spoken remains False). In quiet environments where ambient RMS
never exceeds the silence threshold (200), the recording would wait
indefinitely. The new _max_wait parameter fires the silence callback
after the timeout, triggering the normal "No speech detected" flow.

Subject: [PATCH 34/93] fix: persistent audio stream and silence detection
 improvements

- Keep InputStream alive across recordings to avoid CoreAudio hang on
  repeated open/close cycles on macOS.  New _ensure_stream() creates the
  stream once; start()/stop()/cancel() only toggle frame collection.
- Add _close_stream_with_timeout() with daemon thread to prevent
  stream.stop()/close() from blocking indefinitely.
- Add generation counter to detect stale stream-open completions after
  cancel or restart.
- Run recorder.cancel() in background thread from Ctrl+C handler to
  keep the event loop responsive.
- Add shutdown() method called on /voice off to release audio resources.
- Fix silence timer reset during active speech: use dip tolerance for
  _resume_start tracker so natural speech pauses (< 0.3s) don't prevent
  the silence timer from being reset.
- Update tests to match persistent stream behavior.

Subject: [PATCH 36/93] refactor: remove dead _generation counter from
 AudioRecorder

The counter was incremented in start/stop/cancel but never read
anywhere in the codebase. The race condition it was meant to guard
against is practically impossible with the persistent stream design.

Subject: [PATCH 37/93] feat: add /voice command for auto voice reply in
 Telegram gateway

- /voice on: reply with voice when user sends voice messages
- /voice tts: reply with voice to all messages
- /voice off: disable, text-only replies
- /voice status: show current mode
- Per-chat state persisted to gateway_voice_mode.json
- Dedup: skips auto-reply if agent already called text_to_speech tool
- drop_pending_updates=True to ignore stale Telegram messages on restart
- 25 tests covering command handler, reply logic, and edge cases

Subject: [PATCH 39/93] fix: Discord voice bubble + edge-tts mp3/ogg format
 mismatch

- Send Discord voice messages with flags=8192 and waveform metadata
  so they render as native voice bubbles instead of file attachments
- Use .mp3 output path for TTS so edge-tts opus conversion works
  correctly (edge always outputs mp3, convert was skipped for .ogg)
- Use actual file_path from TTS result after potential opus conversion

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Phase 2 of voice channel support: bot listens to users speaking in VC,
transcribes speech via Groq Whisper, and processes through the agent pipeline.

- Add VoiceReceiver class for RTP packet capture, NaCl/DAVE decryption, Opus decode
- Add silence detection and per-user PCM buffering
- Wire voice input callback from adapter to GatewayRunner
- Fix adapter dict key: use Platform.DISCORD enum instead of string
- Fix guild_id extraction for synthetic voice events via SimpleNamespace raw_message
- Pause/resume receiver during TTS playback to prevent echo

+---
+
+# Voice Mode
+
+Hermes Agent supports full voice interaction across CLI and messaging platforms. Talk to the agent using your microphone, hear spoken replies, and have live voice conversations in Discord voice channels.
+
+## Overview
+
+| Feature | Platform | Description |
+|---------|----------|-------------|
+| **Interactive Voice** | CLI | Press Ctrl+B to record, agent auto-detects silence and responds |
+| **Auto Voice Reply** | Telegram, Discord | Agent sends spoken audio alongside text responses |
+| **Voice Channel** | Discord | Bot joins VC, listens to users speaking, speaks replies back |
+
+## Requirements
+
+### Python Packages
+
+```bash
+# CLI voice mode (microphone + audio playback)
+pip install hermes-agent[voice]
+
+# Discord + Telegram messaging (includes discord.py[voice] for VC support)
+pip install hermes-agent[messaging]
+
+# Premium TTS (ElevenLabs)
+pip install hermes-agent[tts-premium]
+
+# Everything at once
+pip install hermes-agent[all]
+```
+
+| Extra | Packages | Required For |
+|-------|----------|-------------|
+| `voice` | `sounddevice`, `numpy` | CLI voice mode |
+| `messaging` | `discord.py[voice]`, `python-telegram-bot`, `aiohttp` | Discord & Telegram bots |
+| `tts-premium` | `elevenlabs` | ElevenLabs TTS provider |
+
+:::info
+`discord.py[voice]` installs **PyNaCl** (for voice encryption) and **opus bindings** automatically. This is required for Discord voice channel support.
+:::
+
+### System Dependencies
+
+```bash
+# macOS
+brew install portaudio ffmpeg opus
+
+# Ubuntu/Debian
+sudo apt install portaudio19-dev ffmpeg libopus0
+```
+
+| Dependency | Purpose | Required For |
+|-----------|---------|-------------|
+| **PortAudio** | Microphone input and audio playback | CLI voice mode |
+| **ffmpeg** | Audio format conversion (MP3 → Opus, PCM → WAV) | All platforms |
+| **Opus** | Discord voice codec | Discord voice channels |
+
+### API Keys
+
+Add to `~/.hermes/.env`:
+
+```bash
+# Speech-to-Text (at least one required)
+GROQ_API_KEY=your-key              # Groq Whisper — fast, free tier available (recommended)
+VOICE_TOOLS_OPENAI_KEY=your-key    # OpenAI Whisper — alternative
+
+# Text-to-Speech (optional — Edge TTS works without any key)
+ELEVENLABS_API_KEY=your-key        # ElevenLabs — premium quality
+```
+
+---
+
+## CLI Voice Mode
+
+### Quick Start
+
+```
+/voice          Toggle voice mode on/off
+/voice on       Enable voice mode
+/voice off      Disable voice mode
+/voice tts      Toggle TTS output
+/voice status   Show current state
+```
+
+### How It Works
+
+1. Enable voice mode with `/voice on`
+2. **Press Ctrl+B** — a beep plays (880Hz), recording starts
+3. **Speak** — a live audio level bar shows your input: `● [▁▂▃▅▇▇▅▂] ❯`
+4. **Stop speaking** — after 3 seconds of silence, recording auto-stops
+5. **Two beeps** play (660Hz) confirming the recording ended
+6. Audio is transcribed via Whisper and sent to the agent
+7. If TTS is enabled, the agent's reply is spoken aloud
+8. Recording **automatically restarts** — speak again without pressing any key
+
+This loop continues until you press **Ctrl+B** during recording (exits continuous mode) or 3 consecutive recordings detect no speech.
+
+:::tip
+The record key is configurable via `voice.record_key` in `~/.hermes/config.yaml` (default: `ctrl+b`).
+:::
+
+### Silence Detection
+
+Two-stage algorithm detects when you've finished speaking:
+
+1. **Speech confirmation** — waits for audio above the RMS threshold (200) for at least 0.3s, tolerating brief dips between syllables
+2. **End detection** — once speech is confirmed, triggers after 3.0 seconds of continuous silence
+
+If no speech is detected at all for 15 seconds, recording stops automatically.
+
+Both `silence_threshold` and `silence_duration` are configurable in `config.yaml`.
+
+### Streaming TTS
+
+When TTS is enabled, the agent speaks its reply **sentence-by-sentence** as it generates text — you don't wait for the full response:
+
+1. Buffers text deltas into complete sentences (min 20 chars)
+2. Strips markdown formatting and `<think>` blocks
+3. Generates and plays audio per sentence in real-time
+
+### Hallucination Filter
+
+Whisper sometimes generates phantom text from silence or background noise ("Thank you for watching", "Subscribe", etc.). The agent filters these out using a database of 498+ known hallucination phrases across multiple languages.
+
+---
+
+## Gateway Voice Reply (Telegram & Discord)
+
+### Commands
+
+These work in both Telegram and Discord text channels:
+
+```
+/voice          Toggle voice mode on/off
+/voice on       Voice replies only when you send a voice message
+/voice tts      Voice replies for ALL messages
+/voice off      Disable voice replies
+/voice status   Show current setting
+```
+
+### Modes
+
+| Mode | Command | Behavior |
+|------|---------|----------|
+| `off` | `/voice off` | Text only (default) |
+| `voice_only` | `/voice on` | Speaks reply only when you send a voice message |
+| `all` | `/voice tts` | Speaks reply to every message |
+
+Voice mode setting is persisted across gateway restarts.
+
+### Platform Delivery
+
+| Platform | Format | Notes |
+|----------|--------|-------|
+| **Telegram** | Voice bubble (Opus/OGG) | Plays inline in chat. ffmpeg converts MP3 → Opus if needed |
+| **Discord** | Audio file attachment (MP3) | Sent alongside text response |
+
+---
+
+## Discord Voice Channels
+
+The most immersive voice feature: the bot joins a Discord voice channel, listens to users speaking, transcribes their speech, processes through the agent, and speaks the reply back in the voice channel.
+
+### Setup
+
+#### 1. Discord Bot Permissions
+
+If you already have a Discord bot set up for text (see [Discord Setup Guide](../messaging/discord.md)), you need to add voice permissions.
+
+Go to the [Discord Developer Portal](https://discord.com/developers/applications) → your application → **Installation** → **Default Install Settings** → **Guild Install**:
+
+**Add these permissions to the existing text permissions:**
+
+| Permission | Purpose | Required |
+|-----------|---------|----------|
+| **Connect** | Join voice channels | Yes |
+| **Speak** | Play TTS audio in voice channels | Yes |
+| **Use Voice Activity** | Detect when users are speaking | Recommended |
+
+**Updated Permissions Integer:**
+
+| Level | Integer | What's Included |
+|-------|---------|----------------|
+| Text only | `274878286912` | View Channels, Send Messages, Read History, Embeds, Attachments, Threads, Reactions |
+| Text + Voice | `274881432640` | All above + Connect, Speak |
+
+**Re-invite the bot** with the updated permissions URL:
+
+```
+https://discord.com/oauth2/authorize?client_id=YOUR_APP_ID&scope=bot+applications.commands&permissions=274881432640
+```
+
+Replace `YOUR_APP_ID` with your Application ID from the Developer Portal.
+
+:::warning
+Re-inviting the bot to a server it's already in will update its permissions without removing it. You won't lose any data or configuration.
+:::
+
+#### 2. Privileged Gateway Intents
+
+In the [Developer Portal](https://discord.com/developers/applications) → your application → **Bot** → **Privileged Gateway Intents**, enable all three:
+
+| Intent | Purpose |
+|--------|---------|
+| **Presence Intent** | Detect user online/offline status |
+| **Server Members Intent** | Map voice SSRC identifiers to Discord user IDs |
+| **Message Content Intent** | Read text message content in channels |
+
+All three are required for full voice channel functionality. **Server Members Intent** is especially critical — without it, the bot cannot identify who is speaking in the voice channel.
+
+#### 3. Opus Codec
+
+The Opus codec library must be installed on the machine running the gateway:
+
+```bash
+# macOS (Homebrew)
+brew install opus
+
+# Ubuntu/Debian
+sudo apt install libopus0
+```
+
+The bot auto-loads the codec from:
+- **macOS:** `/opt/homebrew/lib/libopus.dylib`
+- **Linux:** `libopus.so.0`
+
+#### 4. Environment Variables
+
+```bash
+# ~/.hermes/.env
+
+# Discord bot (already configured for text)
+DISCORD_BOT_TOKEN=your-bot-token
+DISCORD_ALLOWED_USERS=your-user-id
+
+# STT — at least one required for voice channel listening
+GROQ_API_KEY=your-key              # Recommended (fast, free tier)
+
+# TTS — optional, Edge TTS (free) is the default
+# ELEVENLABS_API_KEY=your-key      # Premium quality
+```
+
+### Commands
+
+```
+/voice join      Bot joins your current voice channel
+/voice channel   Alias for /voice join
+/voice leave     Bot disconnects from voice channel
+/voice status    Show voice mode and connected channel
+```
+
+:::info
+You must be in a voice channel before running `/voice join`. The bot joins the same VC you're in.
+:::
+
+### How It Works
+
+When the bot joins a voice channel, it:
+
+1. **Captures audio** via Discord's UDP socket (RTP packets)
+2. **Decrypts** using NaCl transport encryption (aead_xchacha20_poly1305_rtpsize)
+3. **Decrypts** DAVE end-to-end encryption (Discord Audio/Video Encryption)
+4. **Decodes** Opus audio to raw PCM (48kHz stereo, per-user decoder)
+5. **Detects silence** — 1.5s of silence after at least 0.5s of speech triggers processing
+6. **Converts** PCM to 16kHz mono WAV via ffmpeg
+7. **Transcribes** via Whisper STT (Groq or OpenAI)
+8. **Processes** through the full agent pipeline (session, tools, memory)
+9. **Generates TTS** reply audio
+10. **Plays** the reply in the voice channel
+
+### Text Channel Integration
+
+When the bot is in a voice channel:
+
+- Transcripts appear in the text channel: `[Voice] @user: what you said`
+- Agent responses are sent as text in the channel AND spoken in the VC
+- The text channel is the one where `/voice join` was issued
+
+### Echo Prevention

+The bot automatically pauses its audio listener while playing TTS replies, preventing it from hearing and re-processing its own output.
+
+### Access Control
+
+Only users listed in `DISCORD_ALLOWED_USERS` can interact via voice. Other users' audio is silently ignored.
+
+```bash
+# ~/.hermes/.env
+DISCORD_ALLOWED_USERS=284102345871466496

+## Troubleshooting
+
+### "No audio device found" (CLI)
+
+PortAudio is not installed:
+
+```bash
+brew install portaudio    # macOS
+sudo apt install portaudio19-dev  # Ubuntu
+```
+
+### Bot joins VC but doesn't hear me
+
+- Check your Discord user ID is in `DISCORD_ALLOWED_USERS`
+- Make sure you're not muted in Discord
+- The bot needs a SPEAKING event from Discord before it can map your audio — start speaking within a few seconds of joining
+
+### Bot hears me but doesn't respond
+
+- Verify STT key is set (`GROQ_API_KEY` or `VOICE_TOOLS_OPENAI_KEY`)
+- Check the LLM model is configured and accessible
+- Review gateway logs: `tail -f ~/.hermes/logs/gateway.log`
+
+### Bot responds in text but not in voice channel
+
+- TTS provider may be failing — check API key and quota
+- Edge TTS (free, no key) is the default fallback
+- Check logs for TTS errors
+
+### Whisper returns garbage text
+
+The hallucination filter catches most cases automatically. If you're still getting phantom transcripts:
+
+- Use a quieter environment
+- Adjust `silence_threshold` in config (higher = less sensitive)
+- Try a different STT model

 Hermes Agent supports full voice interaction across CLI and messaging platforms. Talk to the agent using your microphone, hear spoken replies, and have live voice conversations in Discord voice channels.
 
+## Prerequisites
+
+Before using voice features, make sure you have:
+
+1. **Hermes Agent installed** — `pip install hermes-agent` (see [Getting Started](../../getting-started.md))
+2. **An LLM provider configured** — set `OPENAI_API_KEY`, `OPENAI_BASE_URL`, and `LLM_MODEL` in `~/.hermes/.env`
+3. **A working base setup** — run `hermes` to verify the agent responds to text before enabling voice
+
+:::tip
+The `~/.hermes/` directory and default `config.yaml` are created automatically the first time you run `hermes`. You only need to create `~/.hermes/.env` manually for API keys.

Content-Transfer-Encoding: 8bit

New platform adapter that serves a full-featured chat interface via HTTP.
Enables access from any device on the network (phone, tablet, desktop).

Features:
- aiohttp server with WebSocket real-time messaging
- Token-based authentication
- Markdown rendering (marked.js) + code highlighting (highlight.js)
- Voice recording via MediaRecorder API + STT transcription
- Image, voice, and document display

Subject: [PATCH 47/93] feat: add /remote-control command to start web UI on
 demand

Type /remote-control from any platform (Telegram, Discord, etc.) to
instantly start the web UI without restarting the gateway.

- Auto-generates access token if not provided
- Shows URL + token in response
- Optional: /remote-control [port] [token]
- Reports status if already running
- Added to /help command list

Subject: [PATCH 48/93] fix: show correct LAN IP when VPN is active

Detect all network interfaces instead of relying on UDP trick which
returns VPN IP. Prefers 192.168.x.x/10.x.x.x over VPN ranges.
Shows all available IPs in console output.

+---
+
+# Web UI Setup
+
+Access Hermes from any browser on your local network. Open the URL on your phone, tablet, or another computer — no app install, no third-party account needed.
+
+:::info No External Dependencies
+The Web adapter uses `aiohttp`, which is already included in the `[messaging]` extra. No additional packages or external services are required.
+:::
+
+## Overview
+
+| Component | Value |
+|-----------|-------|
+| **Library** | `aiohttp` (HTTP + WebSocket) |
+| **Connection** | Local network (LAN) |
+| **Auth** | Token-based (auto-generated or custom) |
+| **Features** | Markdown, code highlighting, voice messages, images, mobile responsive |
+
+---
+
+## Quick Start
+
+### Option 1: On-Demand via Command
+
+Start the gateway normally, then type from any connected platform (Telegram, Discord, etc.):
+
+```
+/remote-control
+```
+
+The bot replies with the URL and access token. Open the URL on your phone.
+
+You can also specify a custom port and token:
+
+```
+/remote-control 9000 mysecrettoken
+```
+
+### Option 2: Auto-Start with Gateway
+
+Add to `~/.hermes/.env`:
+
+```bash
+WEB_UI_ENABLED=true
+WEB_UI_PORT=8765          # default: 8765
+WEB_UI_TOKEN=mytoken      # auto-generated if empty
+```
+
+Start the gateway:
+
+```bash
+hermes gateway
+```
+
+The web UI starts automatically alongside your other platforms.
+
+---
+
+## Step 1: Configure
+
+Add to `~/.hermes/.env`:
+
+```bash
+# Enable Web UI
+WEB_UI_ENABLED=true
+
+# Port to listen on (default: 8765)
+WEB_UI_PORT=8765
+
+# Bind address (default: 0.0.0.0 = all interfaces, for LAN access)
+# Set to 127.0.0.1 for localhost-only access
+WEB_UI_HOST=0.0.0.0
+
+# Access token (leave empty to auto-generate on each startup)
+WEB_UI_TOKEN=your-secret-token
+```
+
+## Step 2: Start the Gateway
+
+```bash
+hermes gateway
+```
+
+You'll see output like:
+
+```
+[Web] Web UI: http://192.168.1.106:8765
+[Web] Access token: your-secret-token
+```
+
+## Step 3: Open in Browser
+
+1. Open the URL shown in the console on any device on the same network
+2. Enter the access token
+3. Start chatting
+
+---
+
+## Features
+
+### Markdown & Code Highlighting
+
+Bot responses render full GitHub-flavored Markdown with syntax-highlighted code blocks powered by highlight.js.
+
+### Voice Messages
+
+Click the microphone button to record a voice message. The audio is transcribed via Whisper STT and sent to the agent. If voice mode is enabled (`/voice tts`), the bot replies with audio playback in the browser.
+
+### Images & Files
+
+- Images display inline in the chat
+- Documents show as download links
+- Generated images from the agent appear automatically
+
+### Mobile Responsive
+
+The UI adapts to phone screens — full chat experience with touch-friendly input and buttons.
+
+### Typing Indicator
+
+Shows an animated indicator while the agent is processing your message.
+
+### Auto-Reconnect
+
+If the connection drops (server restart, network change), the client automatically reconnects with exponential backoff.
+
+---
+
+## Firewall & Network
+
+### macOS Firewall
+
+macOS may block incoming connections by default. If devices on your network can't connect:
+
+1. **System Settings** > **Network** > **Firewall**
+2. Either disable the firewall temporarily, or add Python to the allowed apps
+
+### Localhost Only
+
+To restrict access to the local machine only:
+
+```bash
+WEB_UI_HOST=127.0.0.1
+```
+
+### Remote Access (Outside LAN)
+
+The Web UI is designed for local network access. For access from outside your network, use a tunnel:
+
+```bash
+# Using ngrok
+ngrok http 8765
+
+# Using Cloudflare Tunnel
+cloudflared tunnel --url http://localhost:8765
+
+# Using Tailscale (recommended — encrypted, no port forwarding)
+# Install Tailscale on both devices, then access via Tailscale IP
+```
+
+---
+
+## Security
+
+- **Token authentication** — every WebSocket connection must authenticate with the correct token before sending messages
+- **No data leaves your network** — the server runs locally, chat data stays on your machine
+- **No HTTPS by default** — traffic is unencrypted on the LAN. Use a reverse proxy or tunnel for encryption
+- **File uploads** require the auth token in the `Authorization` header
+- **Media cleanup** — uploaded and generated files are automatically deleted after 24 hours
+
+---
+
+## Environment Variables
+
+| Variable | Default | Description |
+|----------|---------|-------------|
+| `WEB_UI_ENABLED` | `false` | Enable the web gateway |
+| `WEB_UI_PORT` | `8765` | HTTP server port |
+| `WEB_UI_HOST` | `0.0.0.0` | Bind address (`0.0.0.0` = LAN, `127.0.0.1` = localhost) |
+| `WEB_UI_TOKEN` | (auto) | Access token. Auto-generated if empty. |
+
+---
+
+## Troubleshooting
+
+### "Server not found" on phone
+
+- Verify both devices are on the **same WiFi network**
+- Check if macOS firewall is blocking (see Firewall section above)
+- Try the IP address shown in console output, not `localhost`
+- If using VPN, the console shows all available IPs — try each one
+
+### Port already in use
+
+Change the port in `.env`:
+
+```bash
+WEB_UI_PORT=9000
+```
+
+### Voice recording not working
+
+- Browser must support `MediaRecorder` API (Chrome, Firefox, Safari 14.5+)
+- HTTPS is required for microphone access on non-localhost origins
+- On localhost (`127.0.0.1`), HTTP works fine for microphone
+
+### CDN resources not loading
+
+The UI loads `marked.js` and `highlight.js` from CDN. If you're offline or behind a restrictive proxy, markdown rendering and code highlighting won't work but basic chat still functions.

Subject: [PATCH 50/93] feat: add voice conversation support and futuristic UI
 redesign

- Auto-TTS: voice messages get spoken response (audio first, then text)
- STT: Groq Whisper fallback when VOICE_TOOLS_OPENAI_KEY not set
- Futuristic UI: glassmorphism, centered container, purple theme, glow effects
- Voice bubble: custom waveform player with seek and progress
- Invisible TTS playback via play_tts() method (no audio file in chat)
- Add hermes-web toolset with full tool access
- Register Platform.WEB in toolset/config maps
- Update docs for voice conversation feature

Subject: [PATCH 51/93] feat: add continuous voice mode with VAD silence
 detection
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Voice mode: press mic once to enter, press again to exit
- VAD (Voice Activity Detection) auto-stops recording after 1.5s silence
- Continuous loop: speak → transcribe → agent responds → TTS plays → auto-listen
- Voice mode UI: input bar hides, large mic button centered
- Auto-restart listening when TTS playback finishes
- Fallback: restart listening on text response if no TTS arrives

+"""Tests for the Web UI gateway platform adapter.
+
+Covers:
+1. Platform enum exists with correct value
+2. Config loading from env vars via _apply_env_overrides
+3. WebAdapter init and config parsing (port, host, token)
+4. Token auto-generation when not provided
+5. check_web_requirements function
+6. HTTP server start/stop (connect/disconnect)
+7. Auth screen served on GET /
+8. Media directory creation and cleanup
+9. WebSocket auth handshake (auth_ok / auth_fail)
+10. WebSocket message routing (text, voice)
+11. Auto-TTS play_tts sends invisible playback
+12. Authorization bypass (Web platform always authorized)
+13. Toolset registration (hermes-web in toolset maps)
+14. LAN IP detection (_get_local_ip / _get_local_ips)

+| **Server Channel** | Type in a text channel where the bot is present | Yes (`@botname`) | Bot must be invited to the server |
+
+**DM (recommended for personal use):** Just open a DM with the bot and type — no @mention needed. Voice replies and all commands work the same as in channels.
+
+**Server channels:** The bot only responds when you @mention it (e.g. `@hermesbyt4 hello`). Make sure you select the **bot user** from the mention popup, not the role with the same name.

Subject: [PATCH 56/93] fix: prevent double TTS on Web UI voice messages

When voice mode is enabled and user sends a voice message on Web UI,
both the base adapter auto-TTS (play_audio) and the gateway voice reply
(send_voice) would fire, causing duplicate audio playback. Skip the
gateway voice reply for Web platform voice input since base adapter
already handles it.

Override play_tts in DiscordAdapter to no-op when connected to a voice

in the VC via play_in_voice_channel, so the base adapter's fallback

Subject: [PATCH 59/93] test: add double TTS prevention tests for voice reply
 logic

- Update TestAutoVoiceReply to include skip_double logic: voice input
  is handled by base adapter auto-TTS, gateway runner skips to prevent
  duplicate audio
- Add TestDiscordPlayTtsSkip: verifies Discord adapter skips play_tts
  when bot is in a voice channel (VC playback handled by runner)
- Add TestWebPlayTts: verifies Web adapter sends invisible play_audio
  instead of voice bubble

Subject: [PATCH 60/93] fix: allow voice reply in Discord VC despite
 skip_double guard

When bot is in a Discord voice channel, both base auto-TTS and Discord
play_tts override skip audio. The skip_double guard was also blocking
the runner's _send_voice_reply, resulting in zero audio output in VC.

Now skip_double is overridden when the bot is actively connected to a
voice channel, allowing play_in_voice_channel to handle TTS.

Add comprehensive test matrix covering all platform x input x mode
combinations with full decision table documentation.

+1. **Self-signed HTTPS** with mkcert (recommended):
+   ```bash
+   # Install mkcert
+   brew install mkcert
+   mkcert -install
+
+   # Generate cert for your LAN IP
+   mkcert 192.168.1.106
+
+   # Run a simple HTTPS reverse proxy (requires Node.js)
+   npx local-ssl-proxy --source 8443 --target 8765 \
+     --cert 192.168.1.106.pem --key 192.168.1.106-key.pem
+   ```
+   Then access `https://192.168.1.106:8443` on your iPhone. You'll need to trust the mkcert root CA on iOS: **Settings → General → About → Certificate Trust Settings**.
+
+2. **Caddy reverse proxy** (auto-HTTPS for local networks):
+   ```bash
+   brew install caddy
+   caddy reverse-proxy --from https://192.168.1.106:8443 --to http://127.0.0.1:8765
+   ```
+

+   ```bash
+   ssh -L 8765:127.0.0.1:8765 user@your-mac-ip
+   ```
+   Then access `http://localhost:8765` on the mobile browser — localhost is exempt from HTTPS requirement.

Subject: [PATCH 63/93] fix: extract voice reply logic and add comprehensive
 tests

- Fix tempfile.mktemp() TOCTOU race in Discord voice input (use NamedTemporaryFile)
- Extract voice reply decision from _handle_message into _should_send_voice_reply()
- Rewrite TestAutoVoiceReply to call real method instead of testing a copy
- Add 59 new tests: VoiceReceiver, VC commands, adapter methods, streaming TTS

Subject: [PATCH 64/93] fix(test): use real _strip_markdown_for_tts instead of
 duplicated copy

- Import from tools.tts_tool instead of reimplementing the logic
- Fix test_truncates_long_text: truncation is the caller's job, not the function's
- Remove unused re import

Subject: [PATCH 65/93] fix: voice pipeline thread safety and error handling
 bugs

- Add lock protection around VoiceReceiver buffer writes in _on_packet
  to prevent race condition with check_silence on different threads
- Wire _voice_input_callback BEFORE join_voice_channel to avoid
  losing voice input during the join window
- Add try/except around leave_voice_channel to ensure state cleanup
  (voice_mode, callback) even if leave raises an exception
- Guard against empty text after markdown stripping in base.py auto-TTS
- Add 11 tests proving each bug and verifying the fix

Subject: [PATCH 66/93] fix: 8 voice pipeline bugs with tests proving each fix

1. VoiceReceiver.stop() now acquires _lock before clearing shared state
   to prevent race with _on_packet on the socket reader thread
2. _packet_debug_count moved from class-level to instance-level to avoid
   cross-instance race condition in multi-guild setups
3. play_in_voice_channel uses asyncio.get_running_loop() instead of
   deprecated asyncio.get_event_loop()
4. _send_voice_reply uses uuid for filenames instead of time-based names
   that can collide when two replies happen in the same second
5. Voice timeout now notifies runner via _on_voice_disconnect callback
   so runner cleans up _voice_mode state (prevents orphaned TTS replies)
6. play_in_voice_channel adds PLAYBACK_TIMEOUT (120s) to prevent
   infinite blocking when FFmpeg callback is never called
7. _send_voice_reply moves temp file cleanup to finally block so files
   are always cleaned up even when send_voice/play raises
8. Base adapter auto-TTS wraps play_tts in try/finally with os.remove
   to clean up generated audio files after playback

Subject: [PATCH 67/93] docs: fix 3 inaccuracies found during code-vs-docs
 audit

- voice-mode.md: Discord sends native voice bubbles (OGG/Opus flags=8192),
  not MP3 file attachments. Falls back to file only if voice API fails.
- discord.md: Bot requires @mention by default in server channels
  (DISCORD_REQUIRE_MENTION=true). Previous text incorrectly said no
  mention needed.
- index.md: Fix broken ASCII architecture diagram alignment after
  adding Web adapter box.

Subject: [PATCH 68/93] fix: make STT config env-overridable and fix doc issues
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Code fixes:
- STT model, Groq base URL, and OpenAI STT base URL are now
  configurable via env vars (STT_GROQ_MODEL, STT_OPENAI_MODEL,
  GROQ_BASE_URL, STT_OPENAI_BASE_URL) instead of hardcoded
- Gateway and Discord VC now read stt.model from config.yaml
  (previously only CLI did this — gateway always used defaults)

Doc fixes:
- voice-mode.md: move Web UI troubleshooting to web.md (was duplicated)
- voice-mode.md: simplify "How It Works" for end users (remove NaCl,
  DAVE, RTP internals)
- voice-mode.md: clarify STT priority (OpenAI used first if both keys
  set, Groq recommended for free tier)
- voice-mode.md: document new STT env overrides in config reference
- web.md: remove duplicate Quick Start / Step 1-3 sections
- web.md: add mobile HTTPS mic workarounds (moved from voice-mode.md)
- web.md: clarify STT fallback order

-### Web UI not accessible from other devices on the network
+### Web UI issues (firewall, mobile mic)
 
-The macOS firewall may block incoming connections. Allow the gateway through:
-
-1. **System Settings** → **Network** → **Firewall** → **Options**
-2. Add `/usr/local/bin/python3` (or your Python path) to the allowed list
-3. Or temporarily disable the firewall for testing
-
-On Linux, allow the port through `ufw`:
-
-```bash
-sudo ufw allow 8765/tcp
-```
-
-### Web UI microphone not working on mobile
-
-Mobile browsers require **HTTPS** for microphone access (`navigator.mediaDevices` API). When accessing the Web UI over HTTP on a LAN IP (e.g. `http://192.168.1.x:8765`), the mic button will appear dimmed.
-
-**Workarounds:**
-
-**Android Chrome** — flag the LAN IP as secure:
-1. Open `chrome://flags/#unsafely-treat-insecure-origin-as-secure`
-2. Add your Web UI URL (e.g. `http://192.168.1.106:8765`)
-3. Set to **Enabled** and relaunch Chrome
-
-**iOS Safari / Chrome** — no flag bypass available. Use one of these instead:
-
-1. **Self-signed HTTPS** with mkcert (recommended):
-   ```bash
-   # Install mkcert
-   brew install mkcert
-   mkcert -install
-
-   # Generate cert for your LAN IP
-   mkcert 192.168.1.106
-
-   # Run a simple HTTPS reverse proxy (requires Node.js)
-   npx local-ssl-proxy --source 8443 --target 8765 \
-     --cert 192.168.1.106.pem --key 192.168.1.106-key.pem
-   ```
-   Then access `https://192.168.1.106:8443` on your iPhone. You'll need to trust the mkcert root CA on iOS: **Settings → General → About → Certificate Trust Settings**.
-
-2. **Caddy reverse proxy** (auto-HTTPS for local networks):
-   ```bash
-   brew install caddy
-   caddy reverse-proxy --from https://192.168.1.106:8443 --to http://127.0.0.1:8765
-   ```
-
-3. **SSH tunnel from mobile** (if you have an SSH client like Termius):
-   ```bash
-   ssh -L 8765:127.0.0.1:8765 user@your-mac-ip
-   ```
-   Then access `http://localhost:8765` on the mobile browser — localhost is exempt from HTTPS requirement.
-
-:::tip
-Text chat works on mobile over HTTP without any workaround — only the microphone feature requires HTTPS.
-:::
+See the [Web UI Troubleshooting](../messaging/web.md#troubleshooting) guide for firewall, HTTPS, and mobile microphone issues.

+### Microphone not working on mobile
+
+Mobile browsers require **HTTPS** for microphone access (`navigator.mediaDevices` API). When accessing the Web UI over HTTP on a LAN IP (e.g. `http://192.168.1.x:8765`), the mic button will appear dimmed.
+
+**Android Chrome** — flag the LAN IP as secure:
+1. Open `chrome://flags/#unsafely-treat-insecure-origin-as-secure`
+2. Add your Web UI URL (e.g. `http://192.168.1.106:8765`)
+3. Set to **Enabled** and relaunch Chrome
+
+**iOS Safari / Chrome** — no flag bypass available. Use one of these instead:
+
+1. **Self-signed HTTPS** with mkcert (recommended):
+   ```bash
+   brew install mkcert && mkcert -install
+   mkcert 192.168.1.106
+   npx local-ssl-proxy --source 8443 --target 8765 \
+     --cert 192.168.1.106.pem --key 192.168.1.106-key.pem
+   ```
+   Then access `https://192.168.1.106:8443`. Trust the mkcert root CA on iOS: **Settings > General > About > Certificate Trust Settings**.
+
+2. **SSH tunnel from mobile** (if you have Termius or similar):
+   ```bash
+   ssh -L 8765:127.0.0.1:8765 user@your-mac-ip
+   ```
+   Then access `http://localhost:8765` — localhost is exempt from the HTTPS requirement.
+
+:::tip
+Text chat works on mobile over HTTP without any workaround — only the microphone feature requires HTTPS.
+:::
+
 ### CDN resources not loading
 
 The UI loads `marked.js` and `highlight.js` from CDN. If you're offline or behind a restrictive proxy, markdown rendering and code highlighting won't work but basic chat still functions.

Subject: [PATCH 70/93] refactor: extract get_stt_model_from_config helper to
 eliminate DRY violation

Duplicated YAML config parsing for stt.model existed in gateway/run.py
and gateway/platforms/discord.py. Moved to a single helper in
transcription_tools.py and added 5 tests covering all edge cases.

Subject: [PATCH 74/93] test: add security and hardening tests for voice mode
 fixes

- Path traversal sanitization (Path.name strips ../)
- Media endpoint authentication (401 without token, 404 on traversal)
- hmac.compare_digest usage verification (no == for tokens)
- DOMPurify XSS prevention in HTML template
- Default bind 127.0.0.1 (adapter and config)
- /remote-control token hiding in group chats
- Opus find_library instead of hardcoded paths
- Opus decode error logging (no silent swallow)
- Interrupt _vprint force=True on all 6 calls
- Anthropic interrupt handler in both API call paths
- Update test_web_defaults for new 127.0.0.1 default

Subject: [PATCH 75/93] fix: add macOS Homebrew Opus fallback and fix shutdown
 dict iteration

- Add Homebrew library path fallback when ctypes.util.find_library fails
  on macOS (Apple Silicon + Intel paths, guarded by platform check)
- Fix RuntimeError in gateway stop() by iterating over dict copy
- Update Opus tests to verify find_library-first + conditional fallback

unreachable network interfaces. Add hint about WEB_UI_HOST=0.0.0.0
for phone/tablet access. Add VPN/multi-interface and token exposure
tests (11 new tests).

- Change RTP packet logging from INFO to DEBUG level to reduce noise

- Use per-session chat_id (web_{session_id}) instead of shared "web"

Subject: [PATCH 80/93] feat: integrate faster-whisper local STT with
 three-provider fallback

Merge main's faster-whisper (local, free) with our Groq support into a
unified three-provider STT pipeline: local > groq > openai.

Provider priority ensures free options are tried first. Each provider
has its own transcriber function with model auto-correction, env-
overridable endpoints, and proper error handling.

74 tests cover the full provider matrix, fallback chains, model
correction, config loading, validation edge cases, and dispatch.

 Transcription Tools Module
 
-Provides speech-to-text transcription using OpenAI-compatible Whisper APIs.
-Supports multiple providers with automatic fallback:
-  1. OpenAI (VOICE_TOOLS_OPENAI_KEY) -- paid
-  2. Groq  (GROQ_API_KEY)           -- free tier available
+Provides speech-to-text transcription with three providers:
+
+  - **local** (default, free) — faster-whisper running locally, no API key needed.
+    Auto-downloads the model (~150 MB for ``base``) on first use.
+  - **groq** (free tier) — Groq Whisper API, requires ``GROQ_API_KEY``.
+  - **openai** (paid) — OpenAI Whisper API, requires ``VOICE_TOOLS_OPENAI_KEY``.
 
 Used by the messaging gateway to automatically transcribe voice messages
-sent by users on Telegram, Discord, WhatsApp, and Slack.
-
-Supported models:
-  OpenAI: whisper-1, gpt-4o-mini-transcribe, gpt-4o-transcribe
-  Groq:   whisper-large-v3, whisper-large-v3-turbo, distil-whisper-large-v3-en
+sent by users on Telegram, Discord, WhatsApp, Slack, and Signal.

Subject: [PATCH 82/93] fix: update /voice status to show correct STT provider

Voice status was hardcoded to check API keys only. Now uses the actual
provider resolution (local/groq/openai) so it correctly shows
"local faster-whisper" when installed instead of "Groq" or "MISSING".

Subject: [PATCH 83/93] fix: prevent shutdown deadlock and unblockable Ctrl+C
 on exit

Move stream close outside the lock in shutdown() to prevent deadlock
when audio callback tries to acquire the same lock. Replace single
t.join(timeout) with a polling loop (0.1s intervals) so KeyboardInterrupt
is not blocked during stream cleanup.

 =?UTF-8?q?=20=E2=80=94=20remove=20web=20UI,=20fix=20audio/import/interfac?=

Content-Transfer-Encoding: 8bit

Remove web UI gateway (web.py, tests, docs, toolset, env vars, Platform.WEB
enum) per maintainer request — Nous is building their own official chat UI.

Fix 1: Replace sd.wait() with polling pattern in play_audio_file() to prevent
indefinite hang when audio device stalls (consistent with play_beep()).

Fix 2: Use importlib.util.find_spec() for faster_whisper/openai availability
checks instead of module-level imports that trigger heavy native library
loading (CUDA/cuDNN) at import time.

Fix 3: Remove inspect.signature() hack in _send_voice_reply() — add **kwargs
to Telegram send_voice() so all adapters accept metadata uniformly.

Fix 4: Make session loading resilient to removed platform enum values — skip
entries with unknown platforms instead of crashing the entire gateway.

-# Web UI Setup
-
-Access Hermes from any browser on your local network. Open the URL on your phone, tablet, or another computer — no app install, no third-party account needed.
-
-:::info No External Dependencies
-The Web adapter uses `aiohttp`, which is already included in the `[messaging]` extra. No additional packages or external services are required.
-:::
-
-## Overview
-
-| Component | Value |
-|-----------|-------|
-| **Library** | `aiohttp` (HTTP + WebSocket) |
-| **Connection** | Local network (LAN) |
-| **Auth** | Token-based (auto-generated or custom) |
-| **Features** | Markdown, code highlighting, voice messages, images, mobile responsive |
-
----
-
-## Quick Start
-
-### Option 1: On-Demand via Command
-
-Start the gateway normally, then type from any connected platform (Telegram, Discord, etc.):
-
-```
-/remote-control
-```
-
-The bot replies with the URL and access token. Open the URL on your phone.
-
-You can also specify a custom port and token:
-
-```
-/remote-control 9000 mysecrettoken
-```
-
-### Option 2: Auto-Start with Gateway
-
-Add to `~/.hermes/.env`:
-
-```bash
-WEB_UI_ENABLED=true
-WEB_UI_PORT=8765          # default: 8765
-WEB_UI_TOKEN=mytoken      # auto-generated if empty
-```
-
-Start the gateway:
-
-```bash
-hermes gateway
-```
-
-The web UI starts automatically alongside your other platforms.
-
----
-
-## Features
-
-### Markdown & Code Highlighting
-
-Bot responses render full GitHub-flavored Markdown with syntax-highlighted code blocks powered by highlight.js.
-
-### Voice Conversation
-
-Click the microphone button to record a voice message. The audio is transcribed via Whisper STT (using OpenAI or Groq as fallback) and sent to the agent. The bot automatically replies with audio playback — voice first, then the text response appears. No extra configuration needed.
-
-STT uses `VOICE_TOOLS_OPENAI_KEY` (OpenAI Whisper) if set, otherwise falls back to `GROQ_API_KEY` (Groq Whisper, free tier). If you only need STT, setting `GROQ_API_KEY` is the simplest option. TTS uses Edge TTS (free, no key) by default, or ElevenLabs/OpenAI if configured in `~/.hermes/config.yaml`.
-
-### Images & Files
-
-- Images display inline in the chat
-- Documents show as download links
-- Generated images from the agent appear automatically
-
-### Mobile Responsive
-
-The UI adapts to phone screens — full chat experience with touch-friendly input and buttons.
-
-### Typing Indicator
-
-Shows an animated indicator while the agent is processing your message.
-
-### Auto-Reconnect
-
-If the connection drops (server restart, network change), the client automatically reconnects with exponential backoff.
-
----
-
-## Firewall & Network
-
-### macOS Firewall
-
-macOS may block incoming connections by default. If devices on your network can't connect:
-
-1. **System Settings** > **Network** > **Firewall**
-2. Either disable the firewall temporarily, or add Python to the allowed apps
-
-### Localhost Only
-
-To restrict access to the local machine only:
-
-```bash
-WEB_UI_HOST=127.0.0.1
-```
-
-### Remote Access (Outside LAN)
-
-The Web UI is designed for local network access. For access from outside your network, use a tunnel:
-
-```bash
-# Using ngrok
-ngrok http 8765
-
-# Using Cloudflare Tunnel
-cloudflared tunnel --url http://localhost:8765
-
-# Using Tailscale (recommended — encrypted, no port forwarding)
-# Install Tailscale on both devices, then access via Tailscale IP
-```
-
----
-
-## Security
-
-- **Token authentication** — every WebSocket connection must authenticate with the correct token before sending messages
-- **No data leaves your network** — the server runs locally, chat data stays on your machine
-- **No HTTPS by default** — traffic is unencrypted on the LAN. Use a reverse proxy or tunnel for encryption
-- **File uploads** require the auth token in the `Authorization` header
-- **Media cleanup** — uploaded and generated files are automatically deleted after 24 hours
-
----
-
-## Environment Variables
-
-| Variable | Default | Description |
-|----------|---------|-------------|
-| `WEB_UI_ENABLED` | `false` | Enable the web gateway |
-| `WEB_UI_PORT` | `8765` | HTTP server port |
-| `WEB_UI_HOST` | `127.0.0.1` | Bind address (`0.0.0.0` = LAN, `127.0.0.1` = localhost) |
-| `WEB_UI_TOKEN` | (auto) | Access token. Auto-generated if empty. |
-
----
-
-## Troubleshooting
-
-### "Server not found" on phone
-
-- Verify both devices are on the **same WiFi network**
-- Check if macOS firewall is blocking (see Firewall section above)
-- Try the IP address shown in console output, not `localhost`
-- If using VPN, the console shows all available IPs — try each one
-
-### Port already in use
-
-Change the port in `.env`:
-
-```bash
-WEB_UI_PORT=9000
-```
-
-### Voice recording not working
-
-- Browser must support `MediaRecorder` API (Chrome, Firefox, Safari 14.5+)
-- HTTPS is required for microphone access on non-localhost origins
-- On localhost (`127.0.0.1`), HTTP works fine for microphone
-
-### Microphone not working on mobile
-
-Mobile browsers require **HTTPS** for microphone access (`navigator.mediaDevices` API). When accessing the Web UI over HTTP on a LAN IP (e.g. `http://192.168.1.x:8765`), the mic button will appear dimmed.
-
-**Android Chrome** — flag the LAN IP as secure:
-1. Open `chrome://flags/#unsafely-treat-insecure-origin-as-secure`
-2. Add your Web UI URL (e.g. `http://192.168.1.106:8765`)
-3. Set to **Enabled** and relaunch Chrome
-
-**iOS Safari / Chrome** — no flag bypass available. Use one of these instead:
-
-1. **Self-signed HTTPS** with mkcert (recommended):
-   ```bash
-   brew install mkcert && mkcert -install
-   mkcert 192.168.1.106
-   npx local-ssl-proxy --source 8443 --target 8765 \
-     --cert 192.168.1.106.pem --key 192.168.1.106-key.pem
-   ```
-   Then access `https://192.168.1.106:8443`. Trust the mkcert root CA on iOS: **Settings > General > About > Certificate Trust Settings**.
-
-2. **SSH tunnel from mobile** (if you have Termius or similar):
-   ```bash
-   ssh -L 8765:127.0.0.1:8765 user@your-mac-ip
-   ```
-   Then access `http://localhost:8765` — localhost is exempt from the HTTPS requirement.
-
-:::tip
-Text chat works on mobile over HTTP without any workaround — only the microphone feature requires HTTPS.
-:::
-
-### CDN resources not loading
-
-The UI loads `marked.js` and `highlight.js` from CDN. If you're offline or behind a restrictive proxy, markdown rendering and code highlighting won't work but basic chat still functions.

1. Gate _streaming_api_call to chat_completions mode only — Anthropic and
   Codex fall back to _interruptible_api_call. Preserve Anthropic base_url
   across all client rebuild paths (interrupt, fallback, 401 refresh).

2. Discord VC synthetic events now use chat_type="channel" instead of
   defaulting to "dm" — prevents session bleed into DM context.
   Authorization runs before echoing transcript. Sanitize @everyone/@here
   in voice transcripts.

3. CLI voice prefix ("[Voice input...]") is now API-call-local only —
   stripped from returned history so it never persists to session DB or
   resumed sessions.

4. /voice off now disables base adapter auto-TTS via _auto_tts_disabled_chats
   set — voice input no longer triggers TTS when voice mode is off.

 test_discord_free_response

The mock's app_commands SimpleNamespace lacked choices and Choice attrs,
causing xdist test ordering failures when this mock loaded before

 =?UTF-8?q?=E2=80=94=207=20bug=20fixes=20with=20tests?=

Content-Transfer-Encoding: 8bit

1. Anthropic + ElevenLabs TTS silence: forward full response to TTS
   callback for non-streaming providers (choices first, then native
   content blocks fallback).

2. Subprocess timeout kill: play_audio_file now kills the process on
   TimeoutExpired instead of leaving zombie processes.

3. Discord disconnect cleanup: leave all voice channels before closing
   the client to prevent leaked state.

4. Audio stream leak: close InputStream if stream.start() fails.

5. Race condition: read/write _on_silence_stop under lock in audio
   callback thread.

6. _vprint force=True: show API error, retry, and truncation messages
   even during streaming TTS.

7. _refresh_level lock: read _voice_recording under _voice_lock.

Subject: [PATCH 91/93] fix(test): add missing voice state attrs to CLI stub in
 skin tests

The rebase added voice prompt checks to _get_tui_prompt_fragments but
the test stub was missing _voice_recording, _voice_processing and
_voice_mode attributes, causing AttributeError.

Subject: [PATCH 92/93] fix: persist clean voice transcripts and /voice off
 state

- keep CLI voice prefixes API-local while storing the original user text
- persist explicit gateway off state and restore adapter auto-TTS suppression on restart
- add regression coverage for both behaviors

Subject: [PATCH 93/93] fix: initialize CLI voice state for single-query mode

- initialize voice and interrupt runtime state in HermesCLI.__init__
- prevent chat -q from crashing before run() has executed
- add regression coverage for single-query state initialization
