 ## [Unreleased]
 
-### Fixed
-
-- Android Dashboard sign-in removes pasted line breaks from username and password fields, matching the browser login while preserving every other credential character. (#541)
-- **Relay tool availability avoids repeated Windows loopback delays and preserves multi-PC capabilities.** Host-local Android, Desktop, and Phone paths use explicit IPv4 loopback, while Desktop checks share a bounded health snapshot that preserves per-client advertisements and fails closed when Hermes-Relay is unavailable. (#562, #563)
-- Android keeps saved Dashboard sign-ins bound to their connection when switching gateways, rather than letting a stale resolver route invalidate another connection's session.
-- Bot Mode no longer crashes when different connections have bots with the same profile name. Both the conversation list and Active Now strip preserve each bot's connection, and opening progress appears only on the selected bot.
-- Android feedback uses themed banners and action cards instead of platform toasts and default snackbars. Dashboard errors no longer misidentify missing resources as an outdated Relay. Developer settings includes local-only message previews.
-- Missing chat attachments show their error and retry in the attachment card without repeated global popups. Global action messages occupy the top message area instead of covering the composer.
-- Chat distinguishes session preparation from response streaming and retains initialization errors that arrive before the session acknowledgement. Long-press the agent header to open a live session-diagnostics drawer.
-- Delegated-agent activity survives parent replies and leaves compact history entries for later read-only review. The activity strip appears only while work runs; historical process views cannot stop or dismiss live work. (#447)
-- **`android_*` tools resolve bridge credentials written after host startup.** Requests retry profile-scoped env and active bridge-session credentials after a stale token is rejected, and vision navigation now shares the same current Relay transport instead of the retired standalone default.
-- **`android_setup` accepts both its canonical and legacy schema keys.** `bridge_session_token` and `pairing_code` are accepted, while a missing token returns a structured error.
-- **Android tool setup tests use a temporary Hermes home.** Test runs no longer write bridge settings into a developer environment.

 Wraps the existing relay protocol. When the agent calls `android_*` tools, the tool handler routes through the relay server's bridge channel to the phone.
 
-**Change from upstream:** The bridge channel is part of the multiplexed WSS connection instead of a separate `ws://` relay on port 8766. The legacy standalone `plugin/tools/android_relay.py` was retired in Phase 3 Wave 1 (2026-04-12) and its functionality migrated to two files in the unified relay: `plugin/tools/android_tool.py` (Hermes tools pointing at `http://127.0.0.1:8767` by default — baseline 14 plus v0.4 expansion) and `plugin/relay/channels/bridge.py` (the `BridgeHandler.handle_command(...)` dispatcher that mints request IDs, sends `bridge.command` envelopes over the shared WSS pipe, and awaits matching `bridge.response` envelopes with a 30s timeout). HTTP routes are registered on `plugin/relay/server.py` between `# === PHASE3-bridge-server ===` markers and delegate through the same handler. Wire protocol is frozen — envelopes match the legacy relay byte-for-byte.
