    Replaces the fragile manual "PATCH dance" (reassign + set in_review + open an
    interaction) that repeatedly tripped Paperclip's recovery loops
    (``source_scoped_recovery_action`` / ``stranded_assigned_issue`` /
    ``issue_reopened_via_comment``; see memory reference_paperclip_recovery_loops).

    Two effects in **one DB transaction**, mirroring the proven loop-safe path of
    :func:`reset_case_agents` (raw SQL, not REST):

    1. **Atomic human-owned transition** — a single ``UPDATE`` to the stable end
       state ``{status:'in_review', assignee_agent_id:null,
       assignee_user_id:CHAIM_USER_ID}`` (recovery-loops rule #7). Direct-DB on
       purpose: it bypasses Paperclip's disposition resolver — the very machinery
       whose multi-PATCH/`issue.released` behaviour *causes* the loops — so the
       issue lands human-owned in one shot with no ``done→todo`` flip.
    2. **Durable severity note** — an ``author_type='system'`` comment recording
       severity + reason. System-authored on purpose: the ``route-pending-comments``
       sweep routes only ``author_type='user'`` (chair) comments to the CEO, so a
       system note is inert w.r.t. routing and will **not** re-wake an agent
       (project_comment_delivery_guarantee). No wakeup is issued — the whole point
       is to hand off to the human, not re-invoke an agent.

    The ``agent.escalated`` telemetry event is emitted by the Port wrapper
    (docs/spec/X15) — this is the loop-safe counterpart the CEO/analysts reach
    for instead of leaving an issue agent-owned+blocked.

    issue and the CEO is woken on it. This is the same CEO-child primitive as

    cancellation that fires when an agent is woken on a human-owned parent (the
    exact silent failure the chair hit on 1027-04-26; see TaskMaster #228).

    Wakeup goes through the Paperclip API, never a direct DB insert. Returns
    ``{"status":"ok", "issue_id"(=child), "identifier", ...}`` or

    Triggered by the chair clicking "נתח את פרוטוקול הדיון" / "נתח מחדש" in the
    "מה קרה בדיון" panel (#226). Same delegation shape as
    ``wake_analyst_for_argument_aggregation``: the FastAPI container cannot run
    ``analyze_protocol`` directly (it calls ``claude_session.query_json()``,
    which needs the host-side ``claude`` CLI), so we create a child issue under
    the case's main Paperclip issue, assign it to the company's analyst, and
    trigger a wakeup. The analyst runs the MCP tool locally and reports back.

    ``document_id`` optionally pins the analysis to a specific protocol document
    (when a case holds several protocols — #223).

    Returns a dict shaped for the FastAPI endpoint to serialize as-is:
        {"status": "queued", "sub_issue_id", "analyst_id", "main_issue_id"}
      or {"status": "skipped", "reason": "..."} for non-fatal early outs.
