- /intake now runs match_or_build (matched/suggest/out_of_scope/build); build
seeds the classified category as a hidden meta walked_path entry, matched starts
a flow session, suggest/out_of_scope return prompt data with no session.
- New POST /sessions/{id}/next-node (threads node_text to advance_ai_build) and
GET /escalations (engineer-or-above) for the handoff queue.
- New IntakeResponse(outcome=...)/NextNodeRequest/NextNodeResponse schemas and
require_account_owner_or_admin dep.
- Reconcile Phase-1 intake tests to the new contract (mock match_or_build); add
test_l1_api_ai_build.py covering build/out_of_scope/suggest/next-node/escalations.

Sessions are account-scoped (per spec §7.9), not user-scoped, to support
team coverage. Comment-only fix surfaced by final review.

Mounts /api/v1/l1/* with require_l1_or_coverage on every route. Intake
creates an internal ticket and starts a flow OR adhoc session (PSA queue
merge follows in Phase 2). Step/notes/resolve/escalate delegate to
l1_session_service. escalate-without-walk creates an immediately-
escalated session for the BuildAbortedNoKB path.
ValueError from services → 400. Cross-account session access → 404.
