_notif_gateway_owns_heartbeat decided by the immutable sessions.source column,
so a heartbeat on an ARCHIVED gateway-sourced row (Telegram /reset, idle/daily
auto-reset, compression rotation) was skipped by the Desktop poller and never
registered by the gateway either — restore_heartbeat_watches only claims a key
whose current session_id is that row. The tick belonged to nobody and stayed
due forever, where origin/main's Desktop fired it.
Ownership now uses the same predicate the gateway does: a gateway_routing entry
whose current session_id is this session, with an origin and not suspended
(SessionDB.gateway_routing_entry_for_session; both the session's profile store
and the launch store are consulted so multiplexed and per-profile gateways are
covered). No entry is fail-open, as on main. The check runs after the cheap
is_active/is_due gate so idle sessions never touch the DB per poll.
Probe (SessionStore telegram -> force_new, heartbeat on the archived sid):
before: desktop fired False / gateway watches [] / still due True;
after: desktop fired True / still due False; the current gateway sid is still
left to the gateway (desktop fired False) — the hijack fix stays intact.
hermes_state.py: delete every '# noqa: F401 (re-exported...)' import block (hermes_state_common/errors/guard/
readpool/sessions/fts/dbfile/wal/repair/registry + agent.context_compressor _DB_PERSISTED_MARKER_KEY); keep
only the names hermes_state.py itself uses, without noqa.
hermes_state_registry.py: drop get_shared_session_db/release_shared_session_db/close_shared_session_dbs
aliases; every caller (gateway/, tools/, tui_gateway/, cron/, mcp_serve, run_agent, tests) now imports
acquire/release/close_all/release_or_close from hermes_state_registry.
hermes_state_titles.py: drop set_auto_title_if_empty shim (title_generator keeps its getattr fallback).
Re-remove shim-only names restored by 34abf954bd: latest_user_message_row_id (tests call
latest_message_row_id(key, role='user'); role-targeting assertions kept) and get_session_activity (tests
build the snapshot via agent.session_activity.build_activity_snapshot over db.get_session(sid)).
hermes_state_wal._log_once resolves its dedupe sets as module globals instead of via hermes_state;
hermes_state_repair helpers call module globals directly (tests patch hermes_state_repair.<name>).
Frozen updater surface untouched (update_cmd_maint imports only SessionDB from hermes_state).
For each issue anchor present in BASE 63279301bc non-test .py and absent on HEAD, the BASE comment/docstring block was re-attached at the HEAD location of the code it explained (matched by the distinctive code line / enclosing def). Sentences already covered by an existing HEAD comment were deduped; the issue number always survives. Insert-only: no code lines changed.
