- Session context tracking (where messages come from)
- Session storage (conversations persisted to disk)
- Reset policy evaluation (when to start fresh)
- Dynamic system prompt injection (agent knows its context)

    ``HERMES_AUTO_CONTINUE_FRESHNESS`` (bridged from ``config.yaml``
    ``agent.gateway_auto_continue_freshness`` at gateway startup) and falls
    back to the module default when unset or malformed.  A non-positive value

uD  True iff the agent will actually have Discord tools this session.

    Two conditions must hold:
      1. The `discord` or `discord_admin` toolset is enabled for the
         Discord platform via `hermes tools` (opt-in, default OFF).
      2. `DISCORD_BOT_TOKEN` is set — the tool's `check_fn` gates on it
         at registry time, so the toolset being enabled in config is not
         enough if the token isn't configured.

    Returns False (safe default — keeps the stale-API disclaimer) on any
    error so a bad config can't silently promise tools the agent lacks.

    Build the dynamic system prompt section that tells the agent about its context.

    This is injected into the system prompt so the agent knows:
    - Where messages are coming from
    - What platforms are connected
    - Where it can deliver scheduled task outputs

    When *redact_pii* is True **and** the source platform is in
    ``_PII_SAFE_PLATFORMS``, phone numbers are stripped and user/chat IDs
    are replaced with deterministic hashes before being sent to the LLM.
    Platforms like Discord are excluded because mentions need real IDs.
    Routing still uses the original values (they stay in SessionSource).

    The historical key format is ``agent:main:<platform>:<chat_type>:...`` where
    ``main`` is a static namespace literal (NOT a branch name — branching keys
    off ``session_id``, not this slot). Multi-profile multiplexing reuses this
    slot to carry the profile:

    - default profile (or ``None``/``""``/``"default"``) → ``agent:main`` —
      BYTE-IDENTICAL to every key ever generated, so existing sessions and all
      positional parsers (``parts[2]`` == platform, etc.) are unaffected.
    - named profile ``coder`` → ``agent:coder`` — keeps the same positional
      layout, just a different namespace, so two profiles serving the same
      platform/chat never collide.

    This is the single source of truth for session key construction.

    ``profile`` selects the key namespace (see :func:`_session_key_namespace`).
    It defaults to ``None`` ⇒ the legacy ``agent:main`` namespace, so callers
    that don't multiplex produce byte-identical keys to before. Only the
    multiplexing gateway passes a non-default profile.

    DM rules:
      - DMs include chat_id when present, so each private conversation is isolated.
      - thread_id further differentiates threaded DMs within the same DM chat.
      - Without chat_id, thread_id is used as a best-effort fallback.
      - Without thread_id or chat_id, DMs share a single session.

    Group/channel rules:
      - chat_id identifies the parent group/channel.
      - user_id/user_id_alt isolates participants within that parent chat when available when
        ``group_sessions_per_user`` is enabled.
      - thread_id differentiates threads within that parent chat.  When
        ``thread_sessions_per_user`` is False (default), threads are *shared* across all
        participants — user_id is NOT appended, so every user in the thread
        shares a single session.  This is the expected UX for threaded
        conversations (Telegram forum topics, Discord threads, Slack threads).
      - Without participant identifiers, or when isolation is disabled, messages fall back to one
        shared session per chat.
      - Without identifiers, messages fall back to one session per platform/chat_type.

        When ``multiplex_profiles`` is disabled (default), returns ``None`` so
        keys stay in the legacy ``agent:main`` namespace — byte-identical to
        before. When enabled, prefers the profile the inbound source was routed
        to (``source.profile`` — set by the /p/<profile>/ URL prefix or
        per-credential adapter), falling back to the active profile name.

        The expiry watcher (``GatewayRunner._session_expiry_watcher``) only
        tears an agent down — and only then fires ``on_session_end`` — for
        sessions whose reset policy eventually expires. A ``mode == "none"``
        session never expires (``_is_session_expired`` returns ``False``
        forever), so the watcher will never finalize it.

        This distinction matters for the agent-cache idle sweep: deferring
        idle eviction to "let the watcher finalize it later" is only correct
        when the watcher WILL run for this session. For a ``mode == "none"``
        session, deferring pins the cached agent in memory for the gateway's
        entire lifetime with no finalization ever coming — the exact leak the
        idle sweep exists to relieve. Callers use this predicate to decide
        whether the session store owns the eviction boundary (finalizable) or
        the idle sweep must still reap the agent itself (not finalizable).

        Public wrapper so callers don't reach into policy internals. Errors
        resolving the policy are treated as "not finalizable" (safe: the idle
        sweep falls back to reaping the agent rather than pinning it).

        Mirrors the staleness test in ``_prune_stale_sessions_locked``:
          - no DB handle / no session_id -> False (can't tell — keep)
          - row absent (legacy / not yet persisted) -> False (keep)
          - end_reason is None -> False (alive — keep)
          - end_reason not None -> True (ended — stale)

        Used by ``get_or_create_session`` to self-heal at routing time:
        ``_prune_stale_sessions_locked`` only runs at startup, so a session
        ended in the DB while the gateway stays alive (any path that finalizes
        the row without clearing sessions.json) would otherwise be reused as a
        live routing key and silently swallow every subsequent message until
        the next restart (#54878 — the live-gateway variant of #52804/FM9).
        DB errors are non-fatal — never block routing on a failed lookup.

        Uses the SQLite database as the source of truth because it preserves
        historical session records (ended sessions still count).  The in-memory
        ``_entries`` dict replaces entries on reset, so ``len(_entries)`` would
        stay at 1 for single-platform users — which is the bug this fixes.

        The current session is already in the DB by the time this is called
        (get_or_create_session runs first), so we check ``> 1``.

        Pruning is based on ``updated_at`` (last activity), not ``created_at``.
        A session that's been active within the window is kept regardless of
        how old it is.  Entries marked ``suspended`` are kept — the user
        explicitly paused them for later resume.  Entries held by an active
        process (via has_active_processes_fn) are also kept so long-running
        background work isn't orphaned.

        Pruning is functionally identical to a natural reset-policy expiry:
        the transcript in SQLite stays, but the session_key → session_id
        mapping is dropped and the user starts a fresh session on return.

        ``max_age_days <= 0`` disables pruning; returns 0 immediately.
        Returns the number of entries removed.

        Called on gateway startup after a crash or fast restart to preserve
        in-flight sessions instead of destroying their conversation history
        (#7536).  Only marks sessions updated within *max_age_seconds* to
        avoid touching long-idle sessions.  Sets ``resume_pending=True`` so
        the next incoming message on the same session_key auto-resumes from
        the existing transcript.

        Entries already flagged ``resume_pending=True`` are skipped.  Entries
        explicitly ``suspended=True`` (from /stop or stuck-loop escalation)
        are also skipped.  Terminal escalation for genuinely stuck sessions
        is still handled by the existing ``.restart_failure_counts`` counter
        (threshold 3), which runs after this method and sets ``suspended=True``.

        Returns the number of sessions marked resumable.

        Unlike :meth:`rewrite_transcript` (a hard replace used by /retry),

        survive for audit and stay hidden from re-prompts and search. Mirrors
        the CLI/TUI ``/undo [N]`` behavior via ``SessionDB.rewind_to_message``.

        success, or ``None`` if there's no DB or no user message to back up to.
        ``n`` clamps to the oldest user turn when it exceeds the turn count.
