Four findings addressed:
- High: drop proposed parent_pilot_session_id column; reuse the
existing ai_session_id FK on script_builder_sessions. Add an
origin + ai_session_id coherence invariant.
- High: don't add a 'mode' prop to ScriptBuilderChat (it's
presentational). Introduce a ScriptBuilderTab controller that owns
session lifecycle + submit, renders ScriptBuilderChat unchanged.
- Medium: filter list_sessions / count_user_sessions to origin='standalone'
so pilot_inline scratch sessions don't pollute the /script-builder
dashboard or count against the 5-session cap.
- Medium: applied_at is stamped only when the engineer commits to a
run-action (one_off, TemplateMatchPanel Run), not on banner Apply
click. Corrects a Phase 8 over-eager stamp that would otherwise
multiply across three surfaces.
