Changelog

Phase-by-phase shipping log. Most-recent first.

Phase 47: Imported campaign lifecycle (May 11 2026)

Closed the gap where the bidding ladder assumed every campaign started at Stage 1 Manual CPC. Imported campaigns can now arrive at any rung and the agent picks up management from where they are. 5-component architecture:

Stage classifier (pure function, no I/O)
Configuration audit with health classifications
New campaigns_stage_history table with append-only transitions
Diagnostic rules that ladder-gate on agent_managed_since
BiddingLifecyclePanel UI on every campaign detail page

Sub-phases shipped same week:

47.1: google_ads_started_at column, ready_for_target_roas fallback for imports, external_change capture pre-approval, pending-state UI, history backfill
47.2: MAX hands-free auto-approves imported audits (except misconfigured)
47.3: Manual "Optimize Now" button respects MAX hands-free, auto-executes on click
47.4: Learning-phase respects google_ads_started_at, real-time notifications on auto-execute + auto-rollback
