* security: add mDNS discovery config to reduce information disclosure
mDNS broadcasts can expose sensitive operational details like filesystem
paths (cliPath) and SSH availability (sshPort) to anyone on the local
network. This information aids reconnaissance and should be minimized
for gateways exposed beyond trusted networks.
Changes:
- Add discovery.mdns.enabled config option to disable mDNS entirely
- Add discovery.mdns.minimal option to omit cliPath/sshPort from TXT records
- Update security docs with operational security guidance
Minimal mode still broadcasts enough for device discovery (role, gatewayPort,
transport) while omitting details that help map the host environment.
Apps that need CLI path can fetch it via the authenticated WebSocket.
* fix: default mDNS discovery mode to minimal (#1882) (thanks @orlyjamie)

* fix(gateway): prevent auth bypass when behind unconfigured reverse proxy
When proxy headers (X-Forwarded-For, X-Real-IP) are present but
gateway.trustedProxies is not configured, the gateway now treats
connections as non-local. This prevents a scenario where all proxied
requests appear to come from localhost and receive automatic trust.
Previously, running behind nginx/Caddy without configuring trustedProxies
would cause isLocalClient=true for all external connections, potentially
bypassing authentication and auto-approving device pairing.
The gateway now logs a warning when this condition is detected, guiding
operators to configure trustedProxies for proper client IP detection.
Also adds documentation for reverse proxy security configuration.

* fix(telegram): fall back to text when voice messages forbidden
When TTS auto mode is enabled, slash commands like /status would fail
silently because sendVoice was rejected with VOICE_MESSAGES_FORBIDDEN.
The entire reply would fail without any text being sent.
This adds error handling to catch VOICE_MESSAGES_FORBIDDEN specifically
and fall back to sending the text content as a regular message instead
of failing completely.

* fix(voice-call): prevent audio overlap with TTS queue
Add a TTS queue to serialize audio playback and prevent overlapping
speech during voice calls. Previously, concurrent speak() calls could
send audio chunks simultaneously, causing garbled/choppy output.
Changes:
- Add queueTts() to MediaStreamHandler for sequential TTS playback
- Wrap playTtsViaStream() audio sending in the queue
- Clear queue on barge-in (when user starts speaking)

* fix(voice-call): use iterative queue processing to prevent heap exhaustion
The recursive processQueue() pattern accumulated stack frames, causing
JavaScript heap out of memory errors on macOS CI. Convert to while loop
for constant stack usage regardless of queue depth.

* fix: detect Anthropic 'Request size exceeds model context window' as context overflow
Anthropic now returns 'Request size exceeds model context window' instead of
the previously detected 'prompt is too long' format. This new error message
was not recognized by isContextOverflowError(), causing auto-compaction to
NOT trigger. Users would see the raw error twice without any recovery attempt.
Changes:
- Add 'exceeds model context window' and 'request size exceeds' to
isContextOverflowError() detection patterns
- Add tests that fail without the fix, verifying both the raw error
string and the JSON-wrapped format from Anthropic's API
- Add test for formatAssistantErrorText to ensure the friendly
'Context overflow' message is shown instead of the raw error
Note: The upstream pi-ai package (@mariozechner/pi-ai) also needs a fix
in its OVERFLOW_PATTERNS regex: /exceeds the context window/i should be
changed to /exceeds.*context window/i to match both 'the' and 'model'
variants for triggering auto-compaction retry.
* fix(tests): remove unused imports and helper from test files
Remove WorkspaceBootstrapFile references and _makeFile helper that were
incorrectly copied from another test file. These caused type errors and
were unrelated to the context overflow detection tests.
* fix: trigger auto-compaction on context overflow promptError
When the LLM rejects a request with a context overflow error that surfaces
as a promptError (thrown exception rather than streamed error), the existing
auto-compaction in pi-coding-agent never triggers. This happens because the
error bypasses the agent's message_end → agent_end → _checkCompaction path.
This fix adds a fallback compaction attempt directly in the run loop:
- Detects context overflow in promptError (excluding compaction_failure)
- Calls compactEmbeddedPiSessionDirect (bypassing lane queues since already in-lane)
- Retries the prompt after successful compaction
- Limits to one compaction attempt per run to prevent infinite loops
Fixes: context overflow errors shown to user without auto-compaction attempt
* style: format compact.ts and run.ts with oxfmt
* fix: tighten context overflow match (#1627) (thanks @rodrigouroz)

* feat(discord): add exec approval forwarding to DMs
Add support for forwarding exec approval requests to Discord DMs,
allowing users to approve/deny command execution via interactive buttons.
Features:
- New DiscordExecApprovalHandler that connects to gateway and listens
for exec.approval.requested/resolved events
- Sends DMs with embeds showing command details and 3 buttons:
Allow once, Always allow, Deny
- Configurable via channels.discord.execApprovals with:
- enabled: boolean
- approvers: Discord user IDs to notify
- agentFilter: only forward for specific agents
- sessionFilter: only forward for matching session patterns
- Updates message embed when approval is resolved or expires
Also fixes exec completion routing: when async exec completes after
approval, the heartbeat now uses a specialized prompt to ensure the
model relays the result to the user instead of responding HEARTBEAT_OK.

* fix: reduce log noise for node disconnect/late invoke errors
- Handle both 'node not connected' and 'node disconnected' errors at info level
- Return success with late:true for unknown invoke IDs instead of error
- Add 30-second throttle to skills change listener to prevent rapid-fire probes
- Add tests for isNodeUnavailableError and late invoke handling
* fix: clean up skills refresh timer and listener on shutdown
Store the return value from registerSkillsChangeListener() and call it
on gateway shutdown. Also clear any pending refresh timer. This follows
the same pattern used for agentUnsub and heartbeatUnsub.
* refactor: simplify KISS/YAGNI - inline checks, remove unit tests for internal utilities
* fix: reduce gateway log noise (#1607) (thanks @petter-b)
* test: align agent id casing expectations (#1607)
