Server-assigns a uuid4 id to every AI-generated node (Finding 1 showstopper:
nodes had no id but the advance protocol keys on node_id, so ai_build walks
never advanced past question 1). Replaces the hidden {"node_type":"meta"}
walked_path convention with real category/problem_text/pending_node columns on
l1_walk_sessions (migration 61dda4f615c6) — fixes junk proposals + off-by-one
depth cap (Findings 8,9), and pending_node replays the served node on re-mount
(no duplicate paid LLM call). Intake honors explicit flow_id and adhoc=True
(Findings 4,5); flow_proposals.l1_session_id FK -> CASCADE (Finding 6 time
bomb); L1 category GET is owner+admin like PATCH and require_account_owner_or_admin
delegates to User.can_manage_account (Finding 7); escalate falls back to default
recipients + filters deleted_at + warns when empty (Finding 10). Cleanups: dead
ticket_ref removed, IntakeResponse per-outcome validator, unused acknowledged
dropped, escalations partial index, restored a deleted audit assertion.

Per spec §5.6.1, audit rows are written at session terminal events
(resolve, escalate, escalate_without_walk). log_audit gains an optional
acting_as parameter that propagates the session's acting_as tag
('l1_coverage' for engineer coverers, null for native L1 users).
Final code review flagged this as Important — column existed but was
never populated. Four new integration tests cover all three paths.

resolve: sets status=resolved, helpful, resolution_notes, resolved_at;
flips FlowProposal.validated_by_outcome on helpful=True proposal walks;
closes linked internal ticket. PSA close is a Phase 2 stub.
escalate: marks session + internal ticket as escalated. PSA reassign
deferred to Phase 2.
escalate_without_walk: creates an immediately-escalated adhoc session
with no walked_path, used by the BuildAbortedNoKB → Escalate path.

record_step appends to walked_path JSONB and advances current_node_id
on flow/proposal walks; refuses adhoc sessions. update_notes replaces
walk_notes (used by adhoc walks for debounced autosave); 256KB size cap
to prevent unbounded JSONB growth. Both reject non-active sessions.

Three start_* functions creating L1WalkSession rows with appropriate
session_kind and target id. Engineers acting in L1 mode get
acting_as='l1_coverage' for audit; native l1_tech users get acting_as=None.
step/notes (T13) and resolve/escalate (T14) extend this file next.
