 ## Summary
 
-This feature release adds Bot Mode across saved Hermes gateways, provider usage and limits, and bounded Assistant screen context. It also settles stale Gateway composer state, improves onboarding, and keeps idle Sphere motion efficient.
-
-## Added
-
-- Use Bot Mode as one messenger-style workspace across saved Hermes gateways, with exact gateway/profile ownership and read-only group rooms.
-- Review Codex credential pools, Nous balances, and OpenCode Go windows from one provider-neutral Usage & limits screen.
-- Start a compatible unlocked Assistant invocation with bounded visible text and an available screenshot in the first Standard voice turn.
-
-## Changed
-
-- Follow the Dashboard-first setup path with current screenshots and clearer separation between standard Hermes and optional Relay extensions.
-- Use clear `Hermes-Relay Android` and isolated `HR Candidate` product names without changing package identities or update behavior.
+This patch makes Android session activity follow live Hermes runtime state instead of a five-minute recency estimate. It keeps Working, Starting, Needs input, Idle, Checking, Unavailable, and Background work accurate while preserving stale state until a complete, unambiguous snapshot can safely replace it.
 
 ## Fixed
 
-- Settle orphaned Gateway busy state automatically while preserving active or detached turns owned by another session.
-- Keep the visible idle Sphere gently animated without running hidden, backgrounded, or motion-disabled loops.
-- Retry Windows-hosted `MEDIA:` attachments through the Relay by-path route instead of treating drive-letter paths as expired tokens.
+- Derive session activity from the authoritative live runtime snapshot rather than Dashboard recency.
+- Preserve prior activity when a refresh is incomplete, unsupported, or ambiguously scoped.
+- Keep session drawer labels, timestamps, and active-turn ownership aligned with the exact profile and session.
 
 ## Install / Verify
 
-- App version: **1.13.0** (versionCode **49**).
+- App version: **1.13.1** (versionCode **50**).
 - Standard Chat, sessions, Manage, sharing, profile switching, and Vanilla Hermes voice continue to work against unmodified upstream Hermes.
 - Granular Device Control remains sideload-only; the Google Play build continues to ship Hermes Bridge Core without AccessibilityService Device Control.
-- The optional Relay plugin enhances provider usage, media retry, and device surfaces but remains unnecessary for standard Android chat, sessions, Manage, and Vanilla Hermes voice.
+- The optional Relay plugin remains unnecessary for standard Android chat, sessions, Manage, and Vanilla Hermes voice.

+## Certify Android session activity across lifecycle and profile boundaries
+
+The contract fixture now covers every upstream live status, complete-snapshot
+disappearance, client-side ownership of duplicate durable ids across profiles,
+and older Gateways without `session.active_list`. Before calling the status
+model device-certified:
+
+- Exercise working, quiet tool-heavy work, each pending-input surface, normal
+  completion, Stop, reconnect, app restart, and process recreation against
+  current vanilla upstream.
+- Verify All Profiles with duplicate session ids across two profiles and two
+  saved connections; no late snapshot or old socket generation may mark the
+  wrong row live.
+- Confirm failed/unsupported refresh becomes Unavailable, restart revalidation
+  remains Checking, ambiguous or partially
+  resolved process-wide snapshots infer no absence, a complete empty snapshot
+  settles every unambiguously owned scope, and REST `is_active=true` never
+  renders as Working.
+- Run a background process that outlives its parent turn and verify Background
+  work remains separate from the conversation's Idle state.
+- Pursue an upstream `session.active_list` profile field/filter or an aggregate
+  activity route with explicit profile ownership so multi-profile clients do
+  not need to resolve process-wide rows from durable keys.

+
+## ADR 68 — Android session activity has one profile-scoped authority
+
+**Status:** Accepted (2026-08-25).
+
+**Context.** Dashboard and API-server session lists expose `is_active`, but
+upstream defines it as an unended persisted row updated within the last five
+minutes. It is useful recency metadata, not proof that a model turn is running.
+Android nevertheless used it as a fallback for **Working**, while local
+composer state, detached-turn checkpoints, pending requests, and drawer rows
+each derived activity independently. A completed turn could therefore remain
+Working, a restart could restore an unverified busy state, and an All Profiles
+row could inherit another profile's live status through a bare session id.
+
+Current upstream exposes live authority through the process-wide Gateway
+`session.active_list`. It reports attachable in-memory runtimes as `starting`,
+`working`, `waiting`, or `idle`, with both the live id and durable session key.
+It accepts only an optional `current_session_id`; rows normally have no profile
+metadata or filter. Exact pending-request events carry more specific
+Needs-input ownership. Exact turn terminals and `session.info {running:false}`
+can settle a matching generation. `process.list` is a different contract: a
+background process may remain after its parent model turn is idle.
+
+**Decision.** Android owns one composite activity registry keyed by stable
+connection identity, normalized profile, and durable session id. Runtime ids
+are aliases only within that owner. The same reducer drives drawer badges and
+filters, visible composer state, animation, and accessibility.
+
+The precedence is:
+
+1. An exact pending approval, clarify, sudo, secret, or MCP request is **Needs input**.
+2. A successfully resolved process-wide `session.active_list` row supplies
+   **Starting**, **Working**, or **Idle** to its exact client-owned profile
+   record. Waiting without an exact pending payload remains a conservative
+   needs-input state until the request detail arrives or clears.
+3. An exact terminal event, `session.info {running:false}`, or
+   `session.activate {running:false}` settles only the matching runtime
+   generation.
+4. A matching `process.list` row may add **Background work** independently; it
+   never keeps the conversation Working.
+5. A checkpoint restored after process recreation is **Checking** until
+   revalidated. A failed or unsupported live refresh is **Unavailable**.
+
+Android resolves each active-list row through exact foreground or detached
+ownership already held by that client, or explicit profile metadata if a
+future upstream sends it. A bounded REST directory never proves that a durable
+`session_key` is globally unique. Ambiguous or unresolved rows apply no status.
+Resolved rows from a partial snapshot may update their exact owners, but they
+cannot infer absence. A missing row clears stale live state for a scope only
+when the successful process-wide snapshot was complete and every relevant row
+was unambiguously resolved. A failed refresh does not settle anything. REST
+`is_active`, `last_active`, and relative timestamps never influence execution
+state. Old socket generations, late refreshes, and unscoped session ids cannot
+revive a newer settled entry.
+
+**Consequences.** Working and Needs input describe current upstream-owned
+runtime state instead of recent persistence. All Profiles remains isolated,
+restart recovery is honest about uncertainty, and background processes stay
+visible without mislabeling their parent turn. Older Gateways remain usable
+but show Unavailable when no exact local terminal truth exists. Declarative
+Gateway scenarios cover all four upstream states, complete-snapshot
+disappearance, client-side profile isolation, and method-not-found; physical
+and current-host certification remains tracked in `TODO.md`. An upstream
+profile field/filter or explicitly owned aggregate activity route would remove
+the remaining ambiguity for multi-profile clients.

-v1.13.0 - Bots, usage, and reliable chat
+v1.13.1 - Accurate session activity
 
-Bot Mode now brings bots from saved Hermes gateways into one messenger-style workspace. Settings adds provider-neutral Codex, Nous, and OpenCode Go usage. Compatible Assistant launches can include bounded visible text and an available screenshot. Gateway chats now settle stale busy state automatically, onboarding is clearer, and idle Sphere motion uses less power.
+Session activity now follows live Hermes runtime state instead of a recent-activity estimate. Working, Starting, Needs input, Idle, Checking, Unavailable, and Background work stay accurate, and stale state clears only after a complete, unambiguous update.

@@ -476,6 +476,7 @@ Bottom navigation bar with 4 tabs:
 - **Canonical Bot Chat** — each individual row resolves the exact hidden session titled `Bot Chat` on its owning Gateway. Lookup failure is not absence, so Android creates and materializes the lazy row with `session.title` only after an authoritative empty exact-title result. The dedicated Bot Chat destination retains that route's pooled Gateway client, loads history through the same connection/profile Dashboard, sends only through Gateway, and returns directly to Bot Mode without rebinding Standard Chat or the global connection. `/new` or `/reset` compacts the canonical conversation instead of forking it. The route pool mints a fresh WebSocket ticket per dial, includes the immutable profile in the WebSocket URL, isolates credentials by exact trusted connection origin, and tears down only the removed connection's clients.
 - **Bot group projection** — Android merges the bounded `ui_meta["hermes-bots-groups"]` v3 projection across gateways by durable room identity and newest revision. Rooms and recent messages are visibly read-only; Android does not create, rename, disband, join, send, coordinate member turns, or become a second room-log authority. Binary room images are ignored at this metadata boundary.
 - **Session drawer** (swipe from left or hamburger icon) — session list with title, timestamp, message count. Create, switch, rename, delete, pin/unpin, and archive/restore. The process-owned conversation binding is the single connection/profile/session identity for Chat; selecting an All Profiles row atomically makes its owner the selected agent and persists that profile/session, while merely browsing All Profiles changes no agent state. Lifecycle or locale-driven Activity recreation cannot replace an explicit binding with stale persisted state, and asynchronous list/history/mutation work is accepted only for the binding's exact namespace. A profile lock hides All Profiles and rejects stale/deep-linked cross-profile opens. The All Profiles browser mode otherwise survives Activity state restoration and refetches its rows after recreation. Pin and archive are durable upstream session fields loaded and patched through the owning connection/profile's Dashboard session API; Android does not keep a second local flag registry. Archived rows are requested explicitly so they remain restorable after recreation. Failed mutations roll back the optimistic row, while refresh and deletion reconcile from server truth. When a persisted title is absent, use upstream's first-user-message `preview`, matching the Hermes Desktop session picker; show "Untitled" only when neither value exists.
+- **Authoritative session activity** — one composite registry keyed by connection, normalized profile, and durable session id drives the drawer, filters, grouping, animation, accessibility, and the visible composer. Exact pending approval/clarify/sudo/secret/MCP requests produce **Needs input**; the Gateway's process-wide `session.active_list` supplies **Starting**, **Working**, and **Idle**; exact terminal or `session.info {running:false}` can settle the matching generation. Because active-list rows normally have no profile metadata, Android assigns a row only through exact foreground/detached ownership already held by that client, or explicit profile metadata if a future upstream sends it. A bounded REST directory never proves global uniqueness. Unresolved rows create no status. Resolved rows from a partial snapshot may update their exact owners, but disappearance settles a scope only when the successful process-wide snapshot was completely and unambiguously resolved for it. Restart/checkpoint recovery is **Checking**; a failed or unsupported live refresh is **Unavailable**, never inferred Idle. REST `is_active` remains recency metadata only. `process.list` may add a separate **Background work** indicator and never keeps the parent conversation Working. Old socket generations, bare session ids from another profile, and delayed snapshots cannot revive newer settled state.
 - **Concurrent Gateway chats** — switching sessions, profiles, drafts, or Threads detaches the visible turn without sending `session.interrupt`; each running chat keeps a connection/profile/session-scoped checkpoint and reattaches to its live Gateway session when reopened. Explicit Stop still interrupts. SSE fallback stays single-stream and cancels on navigation.
 - **Queued Gateway follow-ups** — every local queued item is immutably scoped to its originating connection, profile, stored session, transport, and run generation; only that run's completion can make it eligible, and switching sessions shows only that session's queue. Restored text queues retain the same scope, while unavailable/deleted destinations and non-restorable attachment queues fail visibly instead of following the current composer. Drained messages add `queued: true` to `prompt.submit`; ordinary sends omit the field. Authoritative submit rejections (`4004`, `4018`, `4028`, `4029`, `4030`, `4090`, `5008`, `5070`, and `5071`) preserve the server message and never fall through to API-server SSE.
 - **Durable composer drafts** — each connection/profile/session owns one app-private draft containing text, quote/edit context, and pending attachment bytes. Metadata and content-addressed blobs live under Android's no-backup directory, are capped at 64 drafts and 128 MB of retained blobs outside the active draft, flush when Chat backgrounds, and are removed after a successful send. Session/profile/connection navigation saves the previous owner before restoring the destination; an opened cross-profile session uses its actual owning profile rather than the global picker.

 ## API Fallback Compatibility Details
 
+- Dashboard/API session-list `is_active` is a persistence-recency hint: an
+  unended row whose `last_active` is less than five minutes old. It is not a
+  running-turn signal and must never produce Working, Waiting, or Starting.
+- Gateway `process.list` describes separately running background processes. A
+  process may outlive its parent model turn, so clients present that as
+  Background work without keeping the conversation in Working.
+- Upstream can make multi-profile clients safer and simpler by adding profile
+  metadata or a profile filter to `session.active_list`, or by publishing an
+  aggregate activity route with explicit profile ownership. Until then,
+  clients must fail closed on duplicate or unresolved durable keys.
+
 - Android accepts the API server's final-response image data URLs for PNG,
   JPEG, GIF, WebP, and BMP. Decoding is strict: MIME and file signatures must
   agree, encoded and decoded bytes are capped at the upstream 5 MiB limit, and
