 ## [Unreleased]
 
+## [0.4.0-alpha.3] - 2026-08-11
+
 ### Added
 
-- **Image generation stays visible when upstream tool progress is hidden.** A paired Relay can expose read-only image-tool activity from Hermes session state so Android shows and completes its existing generation animation during Standard Gateway turns; the image canvas replaces generic streaming progress and crossfades into the result within one stable assistant bubble. Native Gateway lifecycle events remain authoritative and Relay remains optional.
+- **Windows tray provides focused remote-access management.** The compact host-aware popup covers connection state, per-host Ask/Trusted/Full Access, pending grant dialogs, authorized-client revocation, activity, daemon controls, and settings without adding chat, terminal, plugin, voice, or session surfaces.
+- **Desktop access policy is isolated per Hermes host.** `hermes-relay hosts` lists and selects local pairings and stores fail-closed access modes independently for each canonical relay URL.
+- **Windows CLI installations can add or open the management UI directly.** `hermes-relay ui install|open|status` and the installed UI shim provide a supported lifecycle for optional UI setup, discovery, and activation.
+
+### Changed
+
+- **Daemon connectivity no longer requires a tool grant.** Ask mode can keep an authenticated daemon connected with zero desktop tools attached; Trusted enables command/file tools with task-scoped screen/input grants, while Full Access removes those task prompts only for the selected host.
+- **Windows bundle updates preserve the desktop lifecycle.** The CLI and tray coordinate one verified installer launch, restore the daemon and UI after setup, and permit same-version UI add or repair without silently downgrading a newer CLI.
 
 ### Fixed
 
-- **Promoted voice tasks keep their Chat row through background delivery.** Completing the provider's initial spoken handoff no longer removes an otherwise empty assistant bubble that still owns a running background task.
-- **Android accepts deliberately installed private certificate authorities.** Google Play and sideload builds now use Android's user CA store alongside system roots for self-hosted HTTPS/WSS connections while preserving certificate-chain, hostname, and Relay pin verification.
-- **Malformed code blocks no longer crash Android Markdown rendering.** Syntax highlighting now bounds dependency-provided spans before applying them, preserving valid highlighting while safely ignoring reversed or out-of-bounds ranges.
+- **Background daemon start reports real readiness.** Detached startup now waits for the spawned process to authenticate and connect, and returns actionable log evidence for configuration, authentication, early-exit, and timeout failures.
+- **Local and release tray builds embed the packaged UI.** Development installs use Tauri's production protocol instead of attempting to load a missing localhost development server, and release CI exercises a silent install/uninstall lifecycle.
 - **Windows-trusted certificates work in the desktop CLI.** The packaged Windows binary and newer Node runtimes add the Windows certificate store without dropping bundled or operator-supplied roots, while TLS verification and Relay certificate pinning remain enforced.
 
+## [1.6.2] - 2026-08-11
+
+### Fixed
+
+- **Paired sessions use recognizable device identities.** Relay sessions preserve a client-provided hostname as the primary name, retain model and platform details, and enrich valid reconnects without requiring users to pair again.
+- **Long-lived session expiry is readable.** The Dashboard presents paired-session lifetime in days or weeks with the exact local deadline available in the detail view instead of accumulating hundreds of hours.
+
+## [Android 1.8.1] - 2026-08-09
+
+### Fixed
+
+- **Android preserves complete long-session transcripts.** API-server and profile-scoped Dashboard history reads now use explicit bounded pagination, retain compatibility with older unpaginated responses, and keep edit, retry, sharing, and recovery anchors stable beyond Hermes' latest-500 default window.
+- **Android follows authoritative Gateway turn contracts.** Submit rejections retain the server's message without silently falling through to SSE, event envelopes reconcile consistently, and edit-and-regenerate requests send the required truncation confirmation.
+
+## [Android 1.8.0] - 2026-08-09
+
+### Added
+
+- **Android chat keeps work in context and makes live turns easier to read.** Draft text, edits, quotes, and attachments stay with their connection, profile, and session; conversation search and prompt-turn navigation jump by stable message identity; message actions reveal smoothly on tap; quoted replies use linked previews without placing markup in the composer; assistant replies retain their compact high-contrast bubbles; and pending attachments support preview, removal, and accessible reordering.
+- **Android reasoning and tool activity use a quieter transcript.** Live thinking opens as an inline disclosure and settles to a collapsed Thought row, while consecutive routine reads, searches, commands, browser actions, and device actions share one live activity ticker or concise completed summary. Approvals, failures, generated media, file changes, output risks, and delegated work keep their own visible lifecycle surfaces even when ordinary tool progress is hidden.
+- **Android Profile Shelf makes agent switching immediate without mixing conversations.** The Chat header expands a compact, accessible shelf with ordered profile avatars, a subtle Server-default home badge on the resolved identity, last-session restoration, display hiding, lock controls, and one full switcher shared with Agent Passport.
+- **Android accepts shared text as a new Chat draft.** Hermes Relay now appears in the system sharesheet for text, opens the active profile in a fresh conversation, and fills the composer for review without sending automatically.
+
+### Changed
+
+- **Android appearance controls are more expressive and easier to preview.** Theme presets, accent and shape customization, imported Sphere skins, and custom pet creation share one live-preview workflow while preserving separate agent, background, and companion identities.
+
+### Fixed
+
+- **Android restores complete Gateway activity and makes settled replies speakable.** Successful Gateway turns reconcile structured persisted tool calls even when an upstream server omits live tool lifecycle events, and a configured voice can read a completed assistant reply from its message actions without requiring Voice Mode. While that narration is active, the same message actions expose Stop without cancelling an unrelated chat turn.
+- **Android chat matches standard keyboard, scrolling, and photo behavior.** Sentence capitalization is enabled, physical Enter can send or insert a newline according to a device-level setting, Ctrl/Command+Enter always submits, directional keys stay with the text caret, expanded thinking and tool content retains bottom-follow until the user scrolls away, and portrait attachments honor their EXIF orientation in previews and message viewers.
+- **Android distinguishes live-turn corrections from queued follow-ups.** The composer names its current action with visible text and accessible state, successful gateway redirects show a correction lifecycle marker, and attachment-bearing follow-ups always enter the session-owned queue because the upstream redirect operation is text-only.
+- **Android visibly explains quiet startup work without an empty chat bubble.** The full-size thinking animation now sits directly in the conversation lane with a stable reviewable status until the first answer text arrives, while recovery keeps its explicit reconnecting state.
+- **Android keeps pets and screen chrome inside safe interaction bounds.** Floating companions avoid agent identity rows and controls during scrolling, remain touchable for their menu, and settings headers respect edge-to-edge system insets.
+
+## [Android 1.7.1] - 2026-08-08
+
+### Fixed
+
+- **Android chat follows a growing live reply.** Bottom-owned conversations now observe each replacement of the streaming message list, keeping newly added lines visible while preserving the reader's position after a manual scroll away.
+- **Hosted Hermes onboarding completes through the official Dashboard sign-in path.** Android recognizes hosted account addresses, uses the system-browser native PKCE flow, and resumes the verified Dashboard session after its loopback callback.
+- **Live Android tool cards remain expandable while a run is active.** Streaming Gateway updates preserve stable card identity and merge tool arguments and result previews into the existing row, so details can be opened before the session finishes.
+- **Completed Android replies format Markdown immediately.** Live assistant text keeps its stable plain renderer only while incomplete, then the same owned row transitions to rich code blocks, lists, emphasis, and links without leaving or reopening the session.
+- **Android approval cards require an explicit labeled decision.** Reading or scrolling a guarded command, navigating away, backgrounding, recomposition, later turn activity, and card dismissal cannot submit or locally resolve it; pending requests remain bound to their owning profile and session until an explicit response or authoritative upstream expiry.
+- **Android Agent Passport controls are readable and easy to dismiss.** Safety and speed choices use full-width accessible targets with plain-language selected-state explanations, while a persistent close action and boundary-aware downward swipe make the sheet reliably dismissible without stealing nested content scrolling.
+- **Android queued messages stay with their originating chat.** Follow-ups now retain their exact connection, profile, session, run, route, attachments, and voice context across concurrent Gateway session switches instead of following whichever session is visible when a run finishes.
+- **Android model pickers reject duplicate catalog identities before rendering.** Repeated provider/model rows from cached or refreshed inventories are merged at the provider boundary, while identical model IDs under different providers remain distinct choices with provider-aware reasoning capabilities.
+- **Android session pins and archives survive app restarts.** The session drawer now reads and updates the owning Hermes profile's durable session metadata, rolls failed changes back, and makes unpinned stars clearly distinct in light theme.
+
+## [1.6.1] - 2026-08-08
+
+### Fixed
+
+- **The Dashboard plugin hands hosted Hermes connections to Android reliably.** Mobile setup exposes the canonical Dashboard address and keeps dialog focus handling contained, so system-browser authentication can return to the correct connection without disrupting the Dashboard.
+
+## [Android 1.7.0] - 2026-08-06
+
+### Added
+
+- **Android exposes provider-aware reasoning controls.** The effort drawer consumes exact upstream or optional Relay capability metadata for each provider/model identity, while unmodified or older Hermes installations retain a fail-soft standard fallback including `max` and `ultra`.
+- **Android support information is local, redacted, and reviewable.** Fatal crashes and handled failures share a bounded on-device record, Diagnostics can copy or share the exact reviewed text, and nothing is uploaded automatically.
+
+### Fixed
+
+- **Android chat chrome follows its active interaction state.** Opening the session drawer dismisses the composer keyboard, refreshed sessions keep their newest row visible, and floating pets wait for measured chat terrain, sit flush on supported rails, and treat the complete scroll-to-bottom control as forbidden space.
+- **Android pets and optional model discovery initialize quietly.** Floating companions wait for a measured overlay before taking their home position, and background API model-inventory failures retain actionable local diagnostics without interrupting chat with a generic notice.
+- **Android chat and Voice stay precisely bottom-pinned through replies, restores, and layout changes.** The active tail keeps its stable live renderer until another row takes ownership, restored sessions follow late composer and message measurement without overriding a reader, and bottom-owned transcripts settle to the exact list boundary after replies and keyboard animations instead of leaving a small hidden remainder.
+- **Android Focus voice controls remain responsive.** The modal click-through guard now sits behind the voice UI instead of consuming pointer events from the mic, close, expansion, and panel controls.
+- **Android diagnostics explain what failed and what to try next.** Relay, route, WebSocket, and API checks distinguish the saved route from the redacted request they actually attempted, name the operation, and provide targeted guidance for connection, DNS, timeout, TLS, authentication, rate-limit, and server failures.
+- **Android chat and Voice keep one render identity through recovery.** Checkpoint restore, streamed callbacks, server-ID adoption, and replay now resolve the same owned transcript row before publication, preventing recurring Compose duplicate-key crashes.
+- **Android crash reports retain actionable release context.** Reports identify the Android surface, avoid exposing hosts and credentials, migrate earlier local crash records, and release automation retains exact Play and sideload R8 mappings for retrace.
+
+## [1.6.0] - 2026-08-06
+
+### Added
+
+- **Relay supplies exact provider/model reasoning capabilities when providers expose them.** The bounded, profile-aware overlay resolves dynamic catalogs for OpenAI Codex, Copilot, LM Studio, and Ollama Cloud, keeps provider credentials on the host, and leaves unknown or unavailable catalogs on the advisory fallback.
+
+## [Android 1.6.1] - 2026-08-03
+
+### Fixed
+
+- **Voice capture waits for the microphone to be released.** Manual recording no longer races barge-in teardown, and AudioRecord startup failures now explain how to free or permit the microphone before retrying.
+- **Android text selection stays stable as streamed replies finish.** Chat resets an active selection when live text becomes rich Markdown, preventing selection-handle drags from retaining removed text nodes.
+- **Android session history follows the upstream page-size contract.** The drawer keeps its 200-session window through bounded 100-row requests, avoiding HTTP 422 errors from current dashboard servers while preserving active-profile isolation.
+- **Android no longer mistakes optional-surface auth failures for expired Relay pairing.** Background session refreshes stay out of the global snackbar, Dashboard and API authorization errors name their owning credential, and Relay-only surfaces use consistent Optional, Ready, Reconnecting, Unavailable, and Needs re-pair states. Foreground recovery retries ordinary Relay backoff immediately while preserving server rate limits, and recovery prioritizes Dashboard or host session management while retained credentials are labeled as stored details instead of active pairing.
+- **Voice controls no longer collide with new-chat coaching.** The clean-view hint yields while Voice owns the composer so it cannot cover the expanding Voice drawer.
+
+## [1.5.1] - 2026-08-03
+
+### Fixed
+
+- **Re-pairing repairs one device instead of accumulating duplicate sessions.** An explicit host-approved pair replaces older sessions and refresh credentials for the same device, while the Dashboard and `/relay revoke <token-prefix>` remain available for operator cleanup.
+
+## [Android 1.6.0] - 2026-08-02
+
+### Added
+
+- **Hermes can be selected as Android’s default Digital Assistant.** The opt-in system role supports background and locked-screen invocation, while the separate experimental “Hey Hermes” listener keeps pre-activation audio on the phone and exposes an ongoing Stop control.
+- **Installed Hermes plugins can contribute native Android pages.** Android renders a bounded declarative schema instead of plugin code, keeps write access off until the user grants it, and supports approval-gated agent-created previews through Relay 1.5.0.
+- **Pets can stay with you across the Android app without replacing the agent.** Petdex and imported companions live in an app-level overlay, can be held and dragged, and optionally roam across live-measured chat and settings surfaces without reserving message space. (#267)
+- **Petdex browsing and one-tap installation are built into Appearance.** Search results use lightweight previews, full atlases download only after Install, creator attribution remains visible, and installed pets stay available offline. (#267)
+- **Android can be used in Russian.** Both product flavors include an AI-assisted Russian catalog, language picker support, localized plurals, and refreshed translations for the 1.6 feature set.
+
+### Changed
+
+- **Assistant and floating Voice surfaces use compact, expandable controls.** Opening full Voice continues the same turn and microphone owner instead of restarting the session.
+- **Voice interruption covers generation and playback.** Barge-in follows upstream RMS calibration and timing, exact stop phrases can end an active voice chat, and interrupted spoken context remains private to the next Standard turn.
+- **Profile identity, the Sphere, and pets are separate appearance choices.** Agent avatars identify messages, background visualization controls ambient art, and Floating pet controls the companion independently. (#267)
+- **The Agent Passport exposes more profile state and safer controls.** Profile configuration, skills, routing, reasoning, and scoped API access remain visibly distinct from the active session identity.
+
+### Fixed
+
+- **Voice output recovers when a streaming renderer produces no audio.** Android falls back to basic synthesis after a bounded first-audio timeout, and long Standard Voice uploads no longer retain duplicate encoded audio buffers.
+- **Relay route failover avoids competing reconnect loops.** Route changes settle through one generation-aware reconnect owner instead of rapidly switching between LAN and remote candidates.
+- **Live chat rows keep stable UI identity while upstream state reconciles.** Streamed messages and process rows no longer collide or restart merely because a server identity arrives later.
+- **Floating pets recover from invalid or scrolling terrain.** Roaming uses measured bubble edges, avoids the jump-to-latest control and text overlap, resumes after drag or scrolling, and preserves locomotion, held, drop, and fallback animation states.
+- **Hermes appears and activates in OEM Android assistant pickers.** Required Assist, Voice, recognition-service, and single-microphone lifecycle metadata now agree.
+- **Experimental wake detection handles completed sherpa results and empty speech cleanly.** Tests use the real local microphone/model path, and no-speech activation returns to ready state instead of surfacing a fatal server error.
+
+## [Android 1.5.3] - 2026-07-31
+
+### Fixed
+
+- **Voice transcripts retain stable rows after chat-history reconciliation.** Focus mode uses the same stable Compose identity as the main conversation, preventing duplicate-key crashes when live rows adopt persisted server IDs.
+
+## [1.5.0] - 2026-08-02
+
+### Added
+
+- **Realtime Agent sessions can speak only settled answers.** Clients may enable an optional per-session `final_answer_only` policy that suppresses routine acknowledgements, progress narration, and intermediate commentary while preserving spoken approvals, confirmation questions, blocking failures, and the final Hermes answer.
+- **Agents can draft native Android plugin pages through Relay.** New tools store bounded declarative JSON pages under the authenticated Relay plugin namespace, while Android retains control of enablement, publication, write grants, and persistent removal. Generated pages cannot include executable code, arbitrary network calls, Android intents, or backend action requests.
+## [Android 1.5.2] - 2026-07-28
+
+### Fixed
+
+- **Dashboard sign-in completes across supported providers and network routes.** Self-hosted OIDC stays on the dashboard cookie flow, while Nous Portal opens in the system browser and completes standards-compatible PKCE through HTTPS, private-LAN, or Tailscale dashboard routes.
+- **Replayed chat updates no longer destabilize the conversation list.** Duplicate upstream message identifiers are coalesced before Compose renders them.
+
+## [Android 1.5.1] - 2026-07-26
+
+### Added
+
+- **Voice supports focused and conversational layouts.** Focus keeps spoken turns, Markdown, tools, media, and actions in a compact voice surface, while Conversation opens the full Chat renderer without leaving the active voice session.
+- **Voice can speak only settled answers.** A global Voice setting keeps tool progress, service updates, and intermediate commentary visual while supported voice paths wait to speak the final Hermes answer.
+
+### Changed
+
+- **Chat answers are easier to read in every theme.** Primary assistant text now uses the theme's full-contrast foreground, and chat prose uses a 15sp size with 21sp line height.
+- **Google Play builds target Android 16.** The app now targets API level 36 while retaining its existing minimum-device support.
+
+### Fixed
+
+- **Completed streamed answers render their formatting without losing the reading position.** Markdown headings, lists, emphasis, and code blocks replace the live text renderer only after completion, then the measured trailing edge remains anchored at the bottom.
+- **Standard Voice speaks completed assistant replies again.** Session and message fences no longer suppress a valid final answer during the handoff from generation to narration.
+- **Realtime background work no longer blocks the active voice controls.** A promoted task releases the foreground spinner and microphone while its progress, tools, cancellation, and final result remain available in the owning chat.

 - **Remote routes move every Hermes surface together.** Android uses `GET /health` instead of misclassifying the API server's `405 Method Not Allowed` response to `HEAD`, and the selected Tailscale route now carries Dashboard/Gateway, sessions, Manage, and Standard Voice with API and Relay instead of leaving them pinned to the saved LAN host.

-This alpha makes the desktop direction explicit: Hermes-Relay is a real CLI/TUI with an optional Windows right-click systray—not a second desktop application. The old Tauri/WebView dashboard and its embedded windows are gone. The installed CLI remains the single source of behavior for pairing, TUI, daemon management, grants, audit, diagnostics, chat, voice, and tools.
+This alpha replaces the right-click-only Windows tray with the compact **Hermes-Relay CLI UI** popup while keeping Hermes-Relay's desktop boundary narrow. Chat, the remote TUI, plugins, voice, and agent sessions remain CLI or upstream desktop concerns.

 ## What's changed
 
 ### Added
 
-- **Persistent desktop-use control.** `hermes-relay computer-use status|enable|disable|cancel` stores one local preference, reports daemon privilege and active/pending grants, and can end an active task-scoped grant without relying on a GUI.
-- **Headless grant review.** `hermes-relay grants` lists pending local computer-use requests and supports interactive review plus explicit `approve`, `reject`, and JSON forms for scripts.
-- **Typed Relay chat option.** `chat --relay-chat` sends `chat.send` over WSS and renders typed `stream.event` v1 assistant, tool, artifact, memory, skill, and error lifecycles while preserving the existing gateway path as the default.
-- **Release-parity verification.** One version contract now keeps the npm package, compiled CLI, Rust tray, lockfile, and installer metadata aligned. The Windows verification target covers TypeScript, compiled-binary smoke tests, Rust formatting/lint/check/tests, and installer packaging.
+- **Compact Windows management tray.** The popup provides connection status, host selection, per-host access, pending approval dialogs, recent activity, daemon controls, startup settings, and authorized-client revocation.
+- **Host-aware desktop access.** `hermes-relay hosts` lists and selects paired Hermes instances and stores independent Ask, Trusted, or Full Access policy for each canonical relay URL.
+- **In-window grant decisions.** New computer-use requests bring the tray forward and show the requesting host, scope, reason, and duration with explicit Approve and Reject actions.
+- **Supported UI lifecycle from the CLI.** `hermes-relay ui install|open|status` lets a CLI-only Windows installation add, reveal, or inspect the optional management UI without rerunning setup by hand.
 
 ### Changed
 
-- **Menu-only Windows systray.** The optional tray is a small native Rust process with no application window, WebView, overlay, embedded terminal, chat view, voice view, or settings dashboard. Interactive actions open the installed CLI in a normal terminal.
-- **State- and privilege-aware daemon control.** The menu reports PID-backed daemon state and User/Administrator privilege, disables invalid lifecycle actions, and requests UAC only when **Start/Restart daemon as Administrator…** is explicitly chosen. The tray itself remains unprivileged.
-- **Visible desktop-use safety.** The tray shows enablement, active grant mode and expiry, warns when an Administrator control grant is active, raises a native alert for pending approvals, opens CLI grant review, and provides immediate cancellation and emergency stop.
-- **Per-user Windows installation.** The default PowerShell installer downloads the checksum-verified NSIS package, installs the CLI and optional tray under `~/.hermes/bin`, adds Start-menu shortcuts and user PATH, and can start the tray at sign-in. CLI-only installation remains available with `HERMES_RELAY_INSTALL_SURFACE=cli`.
+- **Daemon startup is connectivity-first.** Ask mode can keep an authenticated daemon connected with zero desktop tools attached, so starting the daemon does not itself grant authority.
+- **Full Access is explicit and host-scoped.** Trusted hosts may use command and file tools while screen/input remains task-granted. Full Access also removes task prompts for screen, input, and file patches for that host, while authentication, audit, revocation, emergency stop, and UAC boundaries remain enforced.
+- **Host changes apply immediately.** Selecting a different host or changing its access mode restarts an already-running daemon and the UI verifies that the daemon URL matches the selected host before showing it as connected.
+- **PowerShell remains first-class.** Agents should prefer the dedicated `desktop_powershell` RPC for native Windows work; `desktop_terminal` remains cmd-compatible for existing callers.
+- **CLI and UI updates share one verified installer.** Bundle updates coordinate shutdown and restart, allow same-version UI repair, and refuse accidental downgrade unless explicitly forced.
 
 ### Fixed
 
-- **Installed-binary diagnostics.** `hermes-relay doctor` reports the physical Bun-compiled executable instead of a virtual embedded-module path, so PATH and install-directory checks describe the binary that actually launched.
-- **Release guardrails.** CLI tag automation rejects version drift, tags not contained in `main`, oversized tray binaries, or a tray process that creates an application window.
+- **Detached daemon start reports real readiness.** `daemon start` waits for the spawned PID to authenticate and connect, and reports configuration, authentication, early-exit, and timeout diagnostics instead of returning a false success.
+- **Normal tray operation no longer requires opening a CLI for grants.** Pending requests are resolved directly in the focused management dialog.
+- **Release checks match the management tray.** CI builds the React assets, validates Tauri metadata, and smoke-tests the packaged tray without obsolete menu-only size or window assertions.
+- **Installed tray builds no longer depend on a localhost development server.** Local and packaged builds embed their UI assets, eliminating the `127.0.0.1 refused to connect` failure.

+3. `scripts/dev.bat install-fast` when the result must run on the connected

+`install-fast` is intentionally phone-specific. Use `install` for a universal
+sideload debug APK or when the target ABI is not arm64. Release builds remain
+universal and are unaffected unless `-Phermes.devAbi` is explicitly supplied.

 # Hermes-Relay — Dev Log
 
+## 2026-08-09 — Gateway activity recovery and chat speech
+
+Successful Android Gateway turns now reconcile against their profile-owned,
+structured session history. This recovers persisted tool calls when an upstream
+Gateway completes a turn without emitting live tool lifecycle events; assistant
+prose is never inspected for inferred activity, and the recovered calls continue
+through the existing Off, Compact, and Detailed display policy.
+
+The Speak message action now follows configured voice readiness and idle output
+state instead of active Voice Mode or presentation style. A settled assistant
+reply can therefore be read aloud directly from chat, while live or provider
+playback still prevents overlapping output. One-shot message narration owns its
+completion state outside Voice Mode and replaces Speak with Stop while active;
+stopping drains only that narration pipeline and does not cancel a chat turn
+started while the response was playing.
+
+## 2026-08-09 — Quiet reasoning and grouped tool activity
+
+Android Chat now treats reasoning and routine tools as transcript scaffolding.
+Visible live reasoning opens automatically without a tinted card, then collapses
+to a quiet Thought disclosure when it settles unless the reader has explicitly
+chosen its state. Empty reasoning remains absent and the existing first-token
+status continues to own the waiting state.
+
+Top-level routine calls retain their source order but render as consecutive
+activity runs. A live run keeps one summary and one latest-activity ticker in a
+stable footprint; a settled run becomes one collapsed summary that can disclose
+the original identity-preserving tool rows. File edits, approval/question tools,
+generated media, failures, output-risk findings, and delegated work split runs
+and retain independent surfaces. Off hides only ordinary activity runs, Compact
+uses compact disclosed rows, and Detailed preserves the full per-tool detail
+surface on demand. Expansion still yields bottom-follow ownership, and each run
+registers its measured bounds as Chat pet terrain.
+
+## 2026-08-09 — Android chat experience and attachment polish
+
+The Android composer now declares sentence capitalization and a Send IME
+action. A device-level setting chooses whether unmodified physical Enter sends
+or inserts a newline; Shift+Enter remains a newline and Ctrl/Command+Enter
+always submits. Every submit route converges on the existing live-turn owner,
+so the current gateway state still decides whether content steers the active
+turn or queues behind it. Directional focus traversal is cancelled while the
+editor owns focus so hardware arrow keys continue to move the caret and
+selection.
+
+Conversation bottom-follow now remains owned when thinking or tool details
+expand. Only an actual drag ending above the bottom yields that ownership, and
+a chat first measured while the IME is already visible now captures the same
+resize-follow state as a keyboard opened after composition.
+
+Bitmap-backed attachment surfaces now apply EXIF rotation and reflection before
+display. Attachment reads and Base64 conversion also leave the UI thread, so
+selecting a larger photo no longer performs the full ingestion path inside the
+activity-result callback.
+
+Composer drafts now belong to the stable connection, profile, and session
+identity. Text, edit context, and pending attachments restore when returning to
+a chat without persisting attachment bytes. Pending attachments expose bounded,
+orientation-aware previews plus explicit remove and reorder controls.
+
+Conversation overflow now opens transcript search with previous/next matches
+and a prompt-turn rail, both keyed to the same stable UI identity as the message
+list. Assistant prose retains the compact bubble and subtle edge treatment that
+keeps it legible above the animated chat background. Tapping a message reveals
+the existing copy, quote, speak, and edit actions with reduced-motion-aware
+expansion and accessible targets.
+
+Quotes are composer-owned structured references instead of raw blockquote text.
+The composer and sent message render a linked, highlighted author preview; the
+transport remains ordinary Markdown so unmodified Desktop and TUI clients show
+a readable quoted reply. Thinking and top-level tools continue to use their
+independent compact thought bubbles and configured compact or full tool cards,
+without an aggregate completion card. The composer also names Correction and
+Queue states with visible labels. Gateway redirects remain text-only:
+follow-ups with attachments are forced through the existing destination-owned
+queue so files cannot be left behind by a correction request.
+
+## 2026-08-08 — Standalone Android thinking status
+
+Blank streaming assistant rows now present the full-size working animation
+directly in the conversation lane above the visible `Still working…` label,
+without painting an empty assistant bubble around the status. The first answer
+token replaces that standalone state with the normal response bubble, while
+recovery retains the distinct `Reconnecting to your answer…` wording. The
+status owns one stable TalkBack description and suppresses animated child
+nodes, avoiding repeated announcements without claiming measurable progress.
+
+## 2026-08-08 — Android text-share draft handoff
+
+The shared Android manifest now advertises a `text/*` `ACTION_SEND` target for
+both app flavors. `MainActivity` accepts only non-blank single-item text shares
+and places them in a process-local, identity-fenced handoff that survives cold
+Compose initialization. Once the configured chat context settles, the app root
+navigates to Chat and delegates draft creation and composer prefill to
+`ChatViewModel`.
+
+The ViewModel reuses the existing new-chat lifecycle, preserving Gateway
+background-turn reconciliation and the active connection/profile/transport
+namespace. Composer prefills use a one-consumer conflated channel so an intent
+received before Chat composition is delivered once. Shared text is never
+routed through message sending; the user must review and submit it explicitly.
+
+## 2026-08-08 — Android Profile Shelf and profile-context identity
+
+Chat profile selection now lives in a collapsible shelf directly below the top
+app bar. The header toggles the shelf, the active capsule opens Agent Passport,
+inactive 48 dp avatars switch context, and a pinned overflow opens the same full
+switcher used by Passport. Saved ordering and hidden state drive both surfaces;
+the selected hidden profile remains disclosed, while a one-identity shelf stays
+out of the layout. Long-press actions expose inspection, Passport, profile lock,
+and hiding without adding activity or presence claims.
+
+The shelf uses the chat surface instead of a second elevated toolbar. A neutral
+active capsule, 36 dp avatar artwork inside 48 dp targets, compact spacing, and
+a contained overflow affordance keep the row visually subordinate to Chat. When
+Server default resolves to a concrete profile, that profile's avatar remains
+the identity and a small home badge discloses its default routing role.
+Local avatar lookup remains keyed to the Server-default presentation identity,
+so an image customized while that row is selected appears consistently in both
+the Chat header and shelf rather than being re-keyed to whichever explicit
+profile is currently active.
+
+The Server-default sentinel is now distinct from a profile literally named
+`default`. Profile selection restores the last compatible connection/profile/
+transport session, otherwise leaves a fresh draft. Gateway turns detach and
+reconcile in their original session, live SSE turns keep switching disabled,
+and every profile transition clears session-scoped model, provider, personality,
+reasoning, approval, Fast, and YOLO state before the destination session seeds
+its own values. Server sticky-default state is never written.
+
+## 2026-08-08 — Streaming reply tail follow
+
+Android's conversation-bottom follower now reads the current immutable message
+list from Compose state inside its long-lived layout observer. Each streamed
+replacement can therefore advance the viewport as the active bubble gains
+lines, while dragging or scrolling away still releases bottom ownership.
+
+## 2026-08-08 — Settled live replies transition to Markdown
+
+Android now releases the live plain-text renderer immediately after an
+assistant row settles. The transition retains the row's stable UI identity,
+commits the final live frame before replacing its selectable text topology,
+and anchors the same bottom-owned row during the Markdown remeasure. Readers
+who scrolled away retain their viewport, while completed code fences, lists,
+emphasis, links, and interrupted partial replies no longer require session
+navigation before rich rendering appears.
+
+## 2026-08-08 — Explicit-consent ownership for Android approvals
+
+Android no longer treats unrelated Gateway activity or a terminal display event
+as proof that an approval was resolved. Approval cards remain pending through
+scrolling, recomposition, navigation, and background restoration, and retain
+their exact connection, profile, and session ownership. Only a labeled action
+that successfully reaches `approval.respond`, an authoritative upstream expiry,
+or an explicit interrupt can retire the local request; the interrupt path stays
+visibly denied because upstream force-denies it.
+
+## 2026-08-08 — Agent Passport control and dismissal accessibility
+
+The Android Agent Passport keeps its title and explicit close action outside
+the nested content scroller. Material bottom-sheet gestures are enabled again,
+so a downward gesture scrolls long content toward its top boundary before the
+sheet receives the gesture and dismisses; backdrop and Back dismissal retain
+the same callback.
+
+Safety and speed choices now sit below their labels instead of competing for a
+narrow horizontal column. Every segment provides at least a 48 dp target,
+allows two-line labels, exposes radio-selection semantics, and states the
+meaning of the current approval, chat override, or processing-tier choice in
+plain language. The layout remains scrollable on compact heights and at larger
+font scales without moving the close action off-screen.
+
+## 2026-08-08 — Session-owned Android send queues
+
+Android follow-up queues now capture the composing connection/profile context,
+stored session, configured transport, originating run, attachments, and voice
+context as one immutable destination. Queue presentation is filtered to the
+visible session, while completion eligibility is tied to the exact run and live
+Gateway generation that owned the queue. A completion from another session or
+an older live generation cannot dispatch through the current composer route.
+
+In-flight checkpoints retain bounded queued text across process restoration.
+Attachment bytes are not copied into Preferences DataStore; an attachment queue
+that cannot be restored is rejected with a visible review-and-resend notice.
+Connection replacement and session deletion cancel their owned queues, while
+switching among concurrent Gateway sessions preserves each session's queue.
+
+## 2026-08-07 — Provider-owned model inventory identity
+
+Android now normalizes Gateway and API model inventories before publishing
+them to picker consumers. Repeated provider rows merge by canonical provider
+slug, repeated exact model IDs collapse within that provider, and capability
+metadata follows the same provider/model identity. Models intentionally offered
+by different providers remain distinct choices, even when their display labels
+and model IDs match.
+
+The searchable picker groups and keys rows by provider slug plus exact model ID
+instead of provider display text. Cached loads, dynamic refreshes, API aliases,
+and Manage inventory use the same idempotent identity rule, preventing duplicate
+catalog data from reaching keyed Compose lists without hiding valid routes.
+
+## 2026-08-05 — Restored chat bottom ownership and effort fallback clarity
+
+Opening an existing Android session now retains exact bottom ownership through
+late, non-streaming layout changes. Composer capability controls, status rows,
+and restored message content can finish measuring after history first reaches
+the footer; a session-scoped geometry observer corrects those changes without
+using a fixed delay. New-message following remains governed by the smooth
+auto-scroll setting, while a real drag, IME ownership, and the Voice dock keep
+their existing anchors.
+
+The advisory effort drawer now states that Hermes does not advertise exact
+levels for the selected model before explaining why standard options are shown.
+The wording is consistent across all shipped Android locales.
+
+## 2026-08-05 — Provider-aware reasoning effort discovery
+
+The optional Relay plugin now exposes a bearer-protected, profile-aware model
+capability overlay without requiring changes to upstream Hermes. Android merges
+that overlay with the standard `model.options` inventory using exact provider
+and model identities, while older or unpaired Relay installations continue with
+the canonical advisory fallback.
+
+Dynamic LM Studio, Ollama Cloud, and Copilot discovery is bounded by a shared
+network limiter, cached by profile, endpoint, model, and credential fingerprint,
+and fenced across refresh generations. Neither credentials nor internal cache
+scope are returned to clients. Composer controls, Agent Passport, session
+creation, and asynchronous server reconciliation share the same capability
+resolver so a displayed effort cannot silently differ from the value sent.
+
+## 2026-08-05 — Chat drawer and companion terrain ownership
+
+The Chat screen now clears composer focus when the session drawer commits to
+opening, dismissing the IME without continuously clearing focus from drawer
+search or rename fields. Drawer refreshes override keyed list anchoring only
+when the leading session identity changes, keeping the newest row visible after
+activity-based reordering.
+
+Floating companions wait for Chat's measured composer rail before publishing
+their first roaming position. Their collision footprint contains both the
+pointer target and rendered sprite, and the complete scroll-to-bottom control
+envelope is an obstacle rather than a landing perch. Supported rails add no
+visual lift, and the floating-only renderer aligns each frame's opaque bottom
+edge to its canvas baseline so transparent atlas padding cannot make pets hover;
+centered previews and message avatars remain unchanged.
+
+## 2026-08-05 — Measured pet placement and passive model sync
+
+The floating pet now remains unpublished until the app-level overlay has a
+positive measured viewport. Its initial home coordinate is therefore derived
+from the real safe bounds instead of the zero-size pre-measure bounds that
+collapsed to the top-left corner.
+
+API provider inventory remains an optional background catalog on Gateway-led
+connections. A timeout, refusal, or unavailable optional route no longer emits
+a global chat notice during initialization, reconnection, or connection-sheet
+refresh. The failure is retained as a contextual warning in local Diagnostics,
+including the operation, endpoint role, redacted stack trace, preserved network
+cause, and targeted troubleshooting guidance. Cached and Gateway-owned model
+options remain unchanged.
+
+## 2026-08-05 — Stable chat-tail completion
+
+Chat and Voice now treat the active streamed reply as the owner of its live
+renderer until a different row becomes the conversation tail. Stream
+completion retains the existing Compose subtree and list anchor; the full
+Markdown renderer is deferred until the row is no longer active or the session
+is revisited.
+
+The last-in-group timestamp occupies its final geometry from the first
+streaming frame and is only revealed at completion. Measured positive growth
+during an active stream continues to follow the bottom without replacing the
+logical anchor. Once completion layout stabilizes, a bottom-owned transcript
+settles to the exact LazyColumn boundary; proximity slop is reserved for
+retaining follow intent during motion and cannot define the final position. The
+visible footer supplies the exact remaining distance so rounding or adjacent
+layout changes cannot leave a residual forward range.
+
+IME expansion participates in that same viewport owner. A transcript already
+at the bottom advances by the measured viewport-height loss throughout the
+keyboard animation, then settles exactly after inset updates stop on both open
+and close. A transcript being read above the bottom preserves its existing
+anchor, and a real drag cancels keyboard follow immediately. Host-side coverage
+verifies renderer ownership, unchanged bubble height, exact footer settling,
+keyboard arming, viewport loss, completion/IME settlement ownership, and
+history-reading behavior.
+
+## 2026-08-05 — Focus voice input boundary repair
+
+The Focus voice presentation remains modal without installing a consuming
+pointer handler on the full overlay ancestor. Its click-through guard is now a
+behind-content sibling: empty-space gestures cannot reach the chat or drawer,
+while the mic, close, expand/collapse, and panel controls receive their full
+pointer sequence.
+
+Host-side Compose coverage injects real touch events instead of invoking
+semantic click actions. It verifies both child callback delivery and the modal
+background boundary so the two requirements cannot regress independently.
+
+## 2026-08-05 — Actionable Android connection diagnostics
+
+Android diagnostic entries now separate the configured route from the exact
+request operation and path used to test it. Relay health checks identify the
+HTTP `/health` probe that precedes a WebSocket connection, route selection
+records its Dashboard, API, or Relay probe, and WebSocket and API checks name
+their handshake or authentication stage.
+
+Known network and HTTP failure classes attach a bounded next step for refused
+listeners, DNS, routing, timeouts, TLS, credentials, rate limits, missing
+routes, and server failures. The activity list, status timeline, detail dialog,
+copy text, and GitHub issue prefill all carry the same context. Public issue
+text preserves protocol and request paths while redacting hosts, credentials,
+queries, and user information.
+
+## 2026-08-04 — Android transcript identity ownership
+
+ChatHandler now owns one render identity for every published transcript row.
+Checkpoint recovery and all streamed message mutations resolve both the mutable
+server/domain ID and the stable UI identity, so history adoption cannot leave a
+stale client reference that appends a second row. The publication boundary also
+coalesces repeated render identities before Chat or Voice can observe them,
+while keeping the first transcript position and latest state.
+
+Focused coverage composes history reconciliation with checkpoint restore,
+exercises stale post-adoption callbacks, and runs deterministic transition
+sequences across restore, replay, deltas, thinking, and usage updates. Voice's
+temporary transcript row now occupies an auxiliary key namespace disjoint from
+real message rows.
+
+## 2026-08-04 — Android reliability and support foundation
+
+Android fatal capture and centrally classified handled failures now converge on
+a versioned, allowlisted reliability record. Reports are redacted before local
+persistence, capped at 20 records with 14-day retention, written atomically,
+and correlated only with random app/report identifiers. Expected cancellation
+and permission denial remain non-reportable. The pre-existing one-file crash
+format migrates locally on first launch.
+
+Crash recovery leads with the recovery outcome and no-upload guarantee, then
+requires an explicit review before copy, share, or GitHub actions. Diagnostics
+adds an offline support-information review using the same exact redacted text.
+Android issue prefills now request the Android area while repository-wide issue
+ownership remains maintainer-reviewed, and the release workflow retains both
+variant R8 mappings for deterministic retrace.
+
+The architecture audit defers an ANR watchdog, richer allowlisted breadcrumbs,
+hashed product correlation, and OOM emergency writing until their lifecycle,
+privacy, and false-positive behavior can be validated on devices.
+
+## 2026-08-02 — Android Russian localization
+
+Android now ships complete Russian catalogs for the main and sideload builds.
+The in-app language picker, Android locale configuration, chat and voice labels,
+tool and status presentation, diagnostics, onboarding, and plural resources are
+registered against the canonical English catalog. Existing non-English catalogs
+were refreshed to retain exact resource and format-argument parity.
+
+The integration preserves PR #276 as the source contribution while excluding
+unrelated recovery, routing, and test-stability changes from the localization
+scope. The localization registry records Android coverage only; Russian public
+documentation and marketing pages continue to use the canonical English
+fallback until those surfaces are translated separately.
+
+## 2026-07-31 — Upstream-compatible voice interruption semantics
+
+Android full-turn barge-in now follows upstream Hermes' RMS behavior: roughly
+450 ms of quiet-room calibration, a 90th-percentile floor, 3× default
+multiplier, separate generation/playback minimums, a bounded ceiling, 500 ms
+playback grace, and an 80%-majority decision window. Calibration remains frozen
+against speaker output and cannot itself trigger. Renderer-driven phase tracking
+returns to generation thresholds in quiet output gaps and rearms playback grace
+only after a gap of at least one second. Opt-in Logcat diagnostics expose the
+inputs used for device tuning. Barge-in is enabled by default while retaining its master,
+Silero sensitivity, RMS multiplier, playback grace, and resume controls.
+
+Voice stop phrases now use an editable exact-match list that defaults to
+`stop`; clearing the list disables the behavior. A match ends the active voice
+chat in generation or playback, but the same word outside voice chat and longer
+requests continue through normal Hermes input. Continuous-mode pause/resume and
+explicit background-task cancellation retain their narrower state gates.
+
+Interrupting spoken playback arms the upstream one-shot interruption note for
+the next Standard model-bound message. The latch expires after 120 seconds and
+travels only in API-local voice interface context, never in visible or
+persisted user text. Generation and pre-audio synthesis interruption do not mark
+an unspoken reply, Realtime keeps its provider-session context, and silencing remains independent
+from cancellation of promoted background work.
+
+## 2026-07-30 — Expandable Android assistant surface
+
+Android Digital Assistant sessions now open as a compact bottom bar over the
+current app, expand in place for transcript and response detail, and collapse
+without changing the active turn. Open full voice disables only the
+system-owned session UI and reveals the existing app Voice surface, preserving
+the same session, response stream, and microphone owner.
+
+Connection, chat, and voice state machines now have one main-process,
+application-lifetime owner. Assistant activation can initialize and run a cold
+voice turn without constructing or foregrounding `MainActivity`; opening full
+Voice binds the Activity to those same ViewModels and audio resources.
+
+The optional `SYSTEM_ALERT_WINDOW` Voice surface now follows the same
+wide-bar-to-expanded-sheet progression while retaining its minimized bubble.
+It remains a separately user-invoked control for turns that began in the app;
+the Assistant-role session does not require display-over-other-apps permission.
+
+The assistant window is transparent outside the bar or sheet, leaves the
+underlying app unresized, and restricts touch interception to the measured
+surface. Back collapses an expanded surface first; Back from compact, Stop, and
+ordinary dismissal remain terminal. A hidden full-Voice handoff instead follows
+the app-owned turn through its final Closed state.
+Package-scoped lifecycle reconciliation also clears assistant state if Android
+reclaims the separately processed UI while full Voice remains active.
+
+Assistant activation is ID-aware and single-flight. Duplicate delivery cannot
+re-arm capture, Retry replaces a pending readiness attempt, and Stop invalidates
+the attempt before chat, Voice, or microphone mutations. Scoped voice settings
+must hydrate from DataStore before route readiness, and process extraction
+preserves connection-catalog isolation plus the existing gateway route-flip
+settle window.
+
+Physical-device validation on a Samsung SM-S938U confirmed cold invocation over
+a non-Hermes foreground app, compact and expanded presentation without
+foregrounding `MainActivity`, and one main-process microphone owner. Locked
+invocation reached a shown system assistant session without runtime or recorder
+errors; Samsung's secure lock screen prevented screenshot-based visual review.
+
+## 2026-07-30 — Foreground wake-word diagnostics and recovery
+
+The Android-local sherpa listener now treats each non-empty keyword result as a
+completed KWS event, resets the stream immediately, and maps the stored
+confirmation setting to sherpa's native trailing-blank confirmation instead of
+requiring an already-completed result to recur across application frames. Voice
+settings can arm a ten-second test against the same foreground service,
+microphone owner, installed model, and current tuning; it displays live input
+level and reports detection without opening voice or transmitting audio.
+
+Expected empty-transcript responses after activation now record a no-speech
+diagnostic and return voice to its ready state with a retry hint rather than
+surfacing the provider's HTTP error. Other transcription failures retain the
+existing error path. Foreground-service behavior is documented explicitly:
+background detections remain pending behind the notification until Hermes is
+visible; Android default-assistant integration is a separate mode. Opening the
+visible Voice settings screen also reconciles an enabled listener after package
+replacement or process death without adding boot/background auto-start.
+
+Focused wake preferences/core and no-speech classification tests pass.
+Sideload lint, sideload debug packaging, and Google Play debug Kotlin
+compilation pass. This batch adds no model, native library, ABI, permission, or
+network dependency; the existing approximately 6 MB downloaded model and
+packaged sherpa ABI footprint are unchanged.
+
+## 2026-07-30 — Voice transcript identity alignment
+
+Android voice Focus mode now keys transcript rows with the same stable UI
+identity as the main Chat list. A live row may adopt its persisted server
+message ID during history reconciliation while retaining its original Compose
+identity; using the mutable domain ID in the voice overlay could otherwise
+collide during that transition and close the app.
+
+Focused JVM coverage recreates two visible rows with a shared reconciled server
+ID and verifies distinct stable transcript keys. Sideload production and
+Android-test Kotlin compilation pass. The existing full-overlay instrumentation
+fixture remains blocked by its continuously animating surface never reaching
+Compose idleness.
+
+## 2026-07-30 — Opt-in Android Digital Assistant mode
+
+Android now declares an explicit `VoiceInteractionService` and separately
+processed `VoiceInteractionSessionService`. Only Android's user-confirmed
+Assistant role activates the integration. Optional background “Hey Hermes”
+detection reuses the local sherpa model and tuning, releases its recorder before
+the system session opens the existing voice flow, and resumes after session
+exit. Package-scoped lifecycle messages reconcile prompt/listen state,
+transcript/response presentation, cancellation, errors, and process recreation.
+
+The Digital Assistant listener and the existing experimental microphone
+foreground service are separate, mutually exclusive opt-ins. Both retain local
+pre-activation privacy and the shared one-microphone contract. Standard voice
+continues through the upstream Dashboard audio surface. Voice settings include
+role status, setup, removal, runtime status, and the limitation that third-party
+assistants do not receive Google's low-power hotword hardware.
+
+## 2026-07-29 — Full-turn voice interruption and local wake-word preview
+
+Android barge-in now owns one microphone/VAD listener from response generation
+through playback drain for both Standard and Realtime voice. Quiet-room RMS
+calibration freezes before output begins, playback receives a grace interval,
+and model-confirmed majority filtering separates actual interruption from raw
+ducking hints. Turn epochs, stream cancellation, late-delta suppression, and
+an awaited microphone handoff keep an interrupted response from speaking again
+or racing the replacement recording. Exact stop/pause intent is phase-aware,
+while explicit background-task cancellation remains separate from silencing.
+
+An opt-in Android-local “Hey Hermes” preview uses sherpa-onnx in a user-started
+microphone foreground service. Its approximately 6 MB English model is
+downloaded and hash-verified on first enable rather than bundled. The service
+keeps pre-activation audio local, exposes an ongoing Stop notification, pauses
+for active voice, and shares a process-wide single-microphone ownership
+contract with voice recording, barge-in, and realtime diagnostics. The stored
+configuration includes strictness, confirmation frames, new-session behavior,
+and a deliberately inactive future profile-routing shape.
+
+Focused JVM coverage exercises calibration, grace, listener teardown,
+Thinking-to-Speaking ownership, generation/playback interruption, command
+gating, wake preferences, activation, and microphone exclusion. Android
+compilation for both distribution flavors, sideload lint, and sideload APK
+packaging pass with all four supported ABIs. On-device acoustic, foreground
+service, and lifecycle checks remain the corresponding validation gates.
+## 2026-07-28 — Android 1.5.2 production release
+
+Android 1.5.2 shipped from the approved `dev` to `main` release tree as
+versionCode 35. The release adds provider-aware Dashboard sign-in: Nous uses
+the advertised native PKCE system-browser flow, while compatible self-hosted
+providers retain cookie-backed full-page Dashboard authentication. Callback
+origin discovery remains server-driven, private-network HTTP compatibility is
+preserved, and arbitrary public HTTP redirects remain rejected.
+
+The private Play preflight validated the exact application tree before release
+PR #265 merged. The immutable `android-v1.5.2` tag resolves to the resulting
+`main` tip, the production workflow promoted versionCode 35 to the completed
+Google Play production track, and the public GitHub release contains the
+signed AAB, sideload APK, and SHA-256 manifest. The published sideload APK
+checksum was independently verified; replacing the debug-signed phone build
+with the release-signed artifact requires an uninstall because Android
+correctly rejects cross-signature in-place updates.
+
+## 2026-07-27 — Android replayed-message identity reconciliation
+
+Android history reconciliation now collapses reconnect/rejoin replays of the
+same persisted message ID before publishing the transcript to Compose. The
+latest repeated snapshot replaces the value at the message's first transcript
+position, preserving stable ordering, distinct messages, and the LazyColumn
+identity contract without index- or random-key fallbacks.
+
+Focused coverage reproduces the duplicate UUID condition and verifies that the
+authoritative final content wins while every rendered message keeps a unique
+stable UI key.
+
+## 2026-07-26 — Android 1.5.1 patch reconciliation
+
+Android 1.5.1 reconciles the post-1.5.0 voice and chat fixes into versionCode
+34. Voice now offers compact Focus and full Conversation presentation,
+Standard narration preserves valid completed replies, and promoted Realtime
+tasks release foreground voice controls while retaining progress and results.
+
+Completed streamed answers promote from the stable live text node to full
+Markdown only after completion. The measured Markdown row is then positioned
+by its trailing edge until deferred code and attachment measurement settles,
+preventing the LazyColumn from restoring the start of a tall response.
+
+The release also targets Android API level 36. Release notes, in-app What's
+New assets, localized Play notes, and the Play listing reference were updated
+for Android 1.5.1.
+
+## 2026-07-25 — Immutable Android release dispatch repair
+
+Android approval now dispatches the current release workflow definition from
+`main`, while every release job explicitly checks out the immutable
+`android-v*` tag. Validation confirms the dispatched version resolves to that
+checked-out commit and accepts the repository's surface-qualified
+`[Android x.y.z]` changelog heading. Existing tags remain unchanged, and a
+workflow-only correction can resume a failed publication without rebuilding
+from a different application tree.
+
+Audited `.github/workflows/approve-release-android.yml`,
+`.github/workflows/release-android.yml`, `RELEASE.md`, and `DEVLOG.md`.
+
+## 2026-07-25 — Android 1.5.0 final release reconciliation
+
+The final Android 1.5.0 release tree reconciles the accumulated Dashboard-first
+connection, Gateway recovery, background delivery, Agent Passport, onboarding,
+voice, attachment, image-generation, security, localization, and Developer
+Options work into one public release narrative. Android remains version 1.5.0
+with monotonic versionCode 33 because that prepared version was not previously
+tagged or uploaded to production.
+
+Release notes, the in-app What's New assets, localized Play release notes, and
+the Play listing reference now describe the final tree rather than the earlier
+voice-focused candidate. The release train is gated by the exact-tree private
+Play preflight before the `dev` to `main` release merge and public tag.
+
+## 2026-07-25 — Active-turn retention and actionable interaction alerts
+
+Android now promotes user-started chat work to foreground execution until every
+connection/profile/session-scoped turn settles. Independent leases preserve
+concurrent detached Gateway sessions, track sessions paused for input, and
+prevent one completion from stopping protection for siblings. The existing
+Persistent connection switch now extends retention only to idle periods.
+
+The foreground notification reports active and waiting session counts.
+Interaction alerts add privacy-safe expanded profile/session context and an
+explicit review, answer, or secure-response action that deep-links to the exact
+conversation; commands, questions, passwords, secrets, and environment-variable
+names remain confined to the authenticated chat surface.
+
+Audited `ChatViewModel`, `ConnectionViewModel`, `GatewayChatClient`,
+`GatewayKeepAliveService`, `InteractionRequestNotifier`, the shared Android
+manifest, Android settings copy, chat user documentation, and Play foreground
+service declaration guidance.
+
+## 2026-07-24 — Post-connect permission setup
+
+Android onboarding now finishes with a layered permission step after a
+successful Hermes connection. Standard Chat and Manage are explicitly ready
+without a phone grant; Android notifications are recommended through one
+user-triggered runtime prompt; camera, microphone, notification companion, and
+flavor-supported device tools remain individually optional on the centralized
+Permissions screen. Existing just-in-time permission prompts remain available
+when users skip setup.
+
+Coverage separates the Android-version notification policy from the Compose
+presentation and checks the recommended, granted, optional-review, and skip
+states. English and all shipped Android locale catalogs were updated together.

+
+Android contributors now have one cross-platform pre-push command for locale,

+- Routed activity-based Assist invocations through the existing system-assistant activation protocol so both Android entry points share microphone ownership and session lifecycle behavior.
+- Added the required `recognitionService` metadata and a bounded recognition component after device validation showed Samsung could grant the package role while leaving the active voice-interaction service empty. The component does not open the microphone; Hermes assistant sessions continue to use the established transcription pipeline.
+- Declared `CATEGORY_VOICE` on the Assist activity and retained `ACTION_ASSIST` on the explicit activation intent. `VoiceInteractionSession.startVoiceActivity()` adds the voice category, and Android rejects the launch as `START_NOT_VOICE_COMPATIBLE` unless the target filter matches both.

+Standard chat, session history, and Vanilla Hermes voice remain upstream-owned and do not require this plugin.
 
 ## What's changed
 
-### Added
-
-- **Upstream-aware Gateway diagnostics.** Doctor and `/relay/info` expose optional health, configuration-route, and capability signals so clients can explain compatibility gaps without treating an older upstream install as a broken Relay.
-
 ### Fixed
 
-- **Privileged Relay paths enforce host authorization and active grants.** Pairing, Android bridge, terminal, session policy, remote profile configuration, and voice provider origins retain their intended trust boundaries.
-- **Plugin bootstrap remains responsive.** Database initialization and compatibility inspection run outside the Gateway event loop while preserving compatibility with older upstream bootstrap contracts.
-- **Windows Gateway detection is non-signalling.** Starting Relay and periodic profile rescans no longer risk terminating an existing Gateway process.
+- **Recognizable device names.** Relay uses the client hostname as the primary paired-session name when available while preserving compatibility with existing clients.
+- **Persisted device details.** Model and platform metadata survive refresh, reconnect, and Relay restart and appear in the authorized-session API and Dashboard detail view.
+- **Reconnect enrichment without re-pairing.** A valid paired client can fill missing identity metadata during reconnect without changing its authentication state.
+- **Human-readable expiry.** Long paired-session lifetimes use days, weeks, or a calendar date, with the exact local deadline retained for inspection.

 ## Summary
 
-This feature release overhauls voice setup and playback, expands upstream Gateway-aware controls, and makes active Hermes work easier to understand.
-
-## Added
-
-- Standard and Realtime voice settings now have distinct, organized cards for provider, model, and voice selection, with upstream-aware discovery, descriptions, inline previews, waveform feedback, loading skeletons, and an expandable scrolling voice browser.
-- Standard Hermes speech now streams completed reply segments as they arrive. Starting another preview or reply stops the prior audio, and leaving voice mode stops playback.
-- Manage and diagnostics consume upstream health hints and compatibility details, follow canonical Gateway redirects, compress larger RPC payloads, and preserve profile-scoped behavior.
-- Chat surfaces one-turn model selection, queued recovery, project labels, interim Gateway events, and image-generation progress.
+This patch keeps long Hermes conversations complete and aligns Android's
+Gateway behavior with current upstream turn contracts.
 
 ## Fixed
 
-- Voice settings and active-turn correction copy remain complete across supported languages.
-- Chat reactivates the original live Gateway session after a connection loss, avoids duplicate prompt submission when an acknowledgement is lost, and prevents duplicate session rows from crashing the drawer.
-- Relay pairing retains Tailscale and other QR fallback routes when added to an existing Standard connection, recovers older stored routes, and shows a route-specific Dashboard sign-in action instead of leaving remote Chat loading.
-- Remote route checks use the API server's supported `GET /health` contract. Selecting Tailscale now moves Dashboard/Gateway, sessions, Manage, Standard Voice, API, and Relay together instead of leaving dashboard-backed features on the saved LAN host; Manage also labels host-side Nous provider authentication separately from Dashboard sign-in.
-- Hosted Manage OAuth remains bound to the selected dashboard, direct-chat image memory is bounded, and session reset and recovery behavior follow upstream contracts.
+- Complete transcript reads page explicitly across both API-server and
+  profile-scoped Dashboard routes, so sessions beyond Hermes' latest-500
+  default retain stable history, sharing, retry, edit, and recovery anchors.
+- Gateway submit rejections preserve the authoritative server message without
+  silently falling through to SSE.
+- Gateway event envelopes reconcile consistently, and edit-and-regenerate
+  requests send the required truncation confirmation.
 
 ## Install / Verify
 
-- App version: **1.5.0** (versionCode **33**).
-- Standard Chat and Vanilla Hermes voice continue to work against unmodified upstream Hermes.
+- App version: **1.8.1** (versionCode **42**).

+## Structured desktop hardware capabilities
+
+Desktop command, PowerShell, process, and job tools currently execute with the
+desktop daemon's OS-user authority. Add typed hardware operations for reliable
+schemas, audit detail, and task-scoped approval, but do not present hardware
+toggles as isolation while an enabled general shell can reach the same device.
+
+- Define per-host capabilities for commands, files, processes, clipboard,
+  screen, input, connected devices, microphone, and camera. Disabled must win,
+  hardware-sensitive capabilities must default off, and unavailable backends
+  must appear unavailable rather than as inert toggles.
+- Add a **Structured only** access profile that withholds shell/process escape
+  hatches so individual capability toggles become enforceable boundaries.
+- Implement connected-device support first with typed, serial-bound ADB
+  operations (`list`, `shell`, `push`, `pull`, `install`, and bounded logcat)
+  instead of a generic device-exec wrapper.
+- Add microphone and camera only with backend readiness detection, bounded local
+  grants, active-use indicators, audit events, and immediate cancellation.
+- Reconcile legacy `desktop_screenshot` with the task-granted computer screenshot
+  path so screen capture follows one policy.
+
+---
+
+## Android Plugin Studio protocol follow-ups
+
+The first live declarative Plugin lane is host-local: Relay tools create bounded
+draft JSON, Android previews it through the authenticated Dashboard namespace,
+and exact-digest Keep/Remove actions require an Android user tap. Complete the
+multi-session protocol before treating `lifecycle=session` as an isolation claim:
+
+- Derive draft ownership from trusted Hermes task context and store only an HMAC
+  of that identifier; never accept a model-supplied session owner.
+- Filter draft discovery by the Android app's active Hermes session while keeping
+  profile and connection publications separate with explicit precedence.
+- Replace foreground five-second catalog polling with authenticated catalog
+  invalidation events plus ETag polling fallback.
+- Expire abandoned drafts and pending approvals, and add revision-bound profile
+  versus connection promotion targets.
+
+---
+
+## Split fast Android unit tests from resource and screenshot tests
+
+The quick-loop commands now narrow execution to the sideload debug variant and
+support one-class filtering, but all `:app` unit tests still share one Android
+test variant. That variant includes merged Android resources, gives every test
+worker a 2 GiB heap, runs on JDK 21, and enables Roborazzi recording because a
+small subset of Robolectric/screenshot tests requires those settings.
+
+Create a separate resource/screenshot test lane so pure state, parser, routing,
+and formatting tests can run as ordinary JVM tests without Android resource
+packaging. Keep golden-image recording explicit rather than applying it to all
+unit tests, preserve a CI task that runs both lanes, and benchmark cold plus
+warm focused-test latency before adopting the split.
+
+---
+
+## Verify Android native dashboard sign-in on device
+
+Android now selects Custom Tab + PKCE for HTTPS gateways that advertise
+`native_pkce`. The lifecycle-owned callback binds only `127.0.0.1` on an
+OS-assigned port, keeps verifier/state inside the sign-in coroutine, rejects
+untrusted callback noise, and closes on completion, cancellation, navigation,
+or timeout. Encrypted bearer/refresh tokens authenticate Gateway chat, Manage,
+prewarm, and standard voice; sign-out clears both cookie and native sessions.
+Older gateways retain the identified WebView cookie fallback.
+
+Before release, device-test the real Custom Tab → provider → loopback return,
+configuration/background transitions, Manage reload, Gateway chat ticket,
+standard voice, sign-out, and process relaunch. Native bearer exchange remains
+disabled for non-loopback HTTP dashboard addresses; configure HTTPS before
+using the native flow.

Remaining:
-  - **Sphere-skin parity.** Skins are still process-scoped + `adb push` only — the live tick and the importer cover pets, not skins. Extend the tick to `loadUserSkins` and add a `.json` skin import if hot-loading/adding skins in-app is wanted.

   - `**adb push` into `Android/data` hangs on Samsung scoped storage.** Confirmed: pushing a pet pack to `/sdcard/Android/data/<pkg>/files/pets/` stalls (no bytes written) although `adb shell ls` of the dir works.

-- **Pet state-change re-decode can flash one blank frame.** When the agent state switches clips, the first frame of the new clip may briefly be blank during decode; prewarm/hold-last-frame to smooth it. Root cause is the same as the next item: `PetAvatar.Render` re-decodes from disk on every clip change.
-- **Pet frame-sequence memory: no cap or downsample (audit 2026-06-19).** `decodeClip` decodes every frame of the selected clip into `List<ImageBitmap>` at full resolution with no `inSampleSize` downscale to the display size and no frame-count/dimension ceiling — a long sequence of large PNGs can use a lot of RAM and a single very large image can OOM `BitmapFactory`. Add `inSampleSize` downsampling to the avatar's draw size and/or a documented hard cap. Spec now warns authors (prefer sprite sheets), but the renderer doesn't enforce it.
-- **Pet decoded-clip cache (audit 2026-06-19).** `PetAvatar.Render` keys `produceState` on `clip`, so idle→thinking→speaking→idle within one turn re-runs `BitmapFactory.decodeFile` from disk each transition (repeated I/O + GC churn, and the blank-frame flash above). Add a small per-avatar `Map<SphereState, PetFrames>` decode cache.
 - **Pet behavior model — richer state association (spec'd 2026-06-19, `docs/pet-spec.md` "Agent states &amp; pet behavior").** Shipped: the honesty clamp (declared reactivity ∩ `PET_RENDERER_CAPABILITIES`), the friendly `writing` alias, the `**working`/tool-use overlay** (pet-local sub-state from `toolCallBurst`; opt-in `working` clip drives both the swap and the Tools badge), the **one-shot reaction layer** (`greet`/`wake` on appear, `done`/`celebrate` on turn-finish — opt-in, play-once-then-revert, transition-derived; `ONE_SHOT_MAX_MS` backstop), and `**intensity` modulation** (opt-in `reactive.intensity` → live playback speedup ≤1.6× via `rememberUpdatedState`; un-clamps the Activity badge). Voice · Tools · Activity reactivity is now complete. Remaining:
   - `**attention` one-shot (only deferred behavior).** A reaction on notification arrival — needs a host event the avatar doesn't yet receive (unlike `greet`/`done`, which ride state transitions). Would plumb a notification edge into `AvatarRenderState` (or a side channel) + a `PetOneShot.Attention`. Low priority: the avatar is rarely on-screen when notifications land (backgrounded) — see the value analysis; revisit only if the avatar becomes an always-on surface (persistent overlay / Quest port).
-  - **On-device verification (working + one-shots + intensity).** Best seen in clean mode (`AgentTextFlow` feeds `toolCallBurst` + `streamingIntensity` + state transitions). Confirm: a `working` clip swaps in during a tool run and releases ~600ms after (`WORKING_BURST_THRESHOLD` 0.5); a `done` clip plays once on reply completion then returns to idle; a `greet` clip plays once when the avatar appears; with `intensity:true`, a writing/working loop visibly quickens while streaming. Watch for the known clip re-decode flash on each swap (separate TODO — decoded-clip cache).

 - **Undecodable-but-present image appears valid (audit 2026-06-19).** A file that exists but isn't a decodable image passes the loader's `isFile` check, so the pet shows in the picker but renders blank. Documented as a caveat; consider a cheap header sniff at load time if false-valid pets become a support issue.

-Browse Standard and Realtime voice providers, models, and voices in a cleaner layout with inline previews. Standard Hermes replies now speak completed segments while the answer is generated, and new audio stops prior playback. This release also expands Gateway-aware Manage, diagnostics, model selection, recovery, and generation status.
+Long sessions now retain complete history beyond Hermes' latest-500 default, keeping edit, retry, sharing, and recovery anchors stable. Gateway submit rejections preserve the server's message without unintended SSE fallback, while event envelopes and edit-and-regenerate requests follow current upstream contracts.

-现在可在更清晰的界面中浏览标准和实时语音的提供商、模型与声音，并直接试听。标准 Hermes 回复会在生成过程中分段朗读；开始新的音频时会停止之前的播放。本次更新还增强了与 Gateway 兼容的管理、诊断、模型选择、恢复及生成状态。
+新增可在界面中漫游的 Petdex 浮动宠物、由已安装 Hermes 插件提供的安全原生页面，以及支持本地“Hey Hermes”的可选 Android 数字助理。本次更新还新增俄语，并改进语音恢复、路线切换、实时聊天稳定性和宠物移动。

-* Use richer Gateway-aware Manage, diagnostics, model selection, recovery, and generation status.
+* Keep complete history in long sessions beyond Hermes' latest-500 default.
+* Preserve stable edit, retry, sharing, and recovery anchors while paging history.
+* Show authoritative Gateway rejection messages without an unintended fallback.
+* Reconcile Gateway events and edit-and-regenerate requests with current upstream contracts.
