Content Backlog Expansion — D11–D17

2026-06-04. Continues the D1–D10 content series.

• D11 — Trigger taxonomy deep-dive. Each of the 7 DB classes + 4 host classes: what fires them, cadence, blast radius, ownership candidate. Source: v_trigger_universe_census + host census.
• D12 — The 381 infra DB triggers. Bulk-classification guide: which tables, which DML, why INFRA_NO_PROCESS, when to promote. Source: v_trigger_orphan_stale_detector.
• D13 — Stale trigger retirement runbook. The 27 STALE_DISABLED triggers: evidence to retire vs re-enable, owner sign-off, rollback.
• D14 — Event activation guide. The 7 process.* events: payload, delivery lane, consumers, PROC-OWN-05 activation effect.
• D15 — Cross-axis ownership model. How AX-PROCESS owners and AX-TRIGGER owners coordinate; shared vs split ownership of process-relevant triggers.
• D16 — REAL_RUN operations manual. Post-first-REAL_RUN: monitoring, success/failure handling, the 10-process split mechanics, evidence promotion.
• D17 — Officialization audit trail. How canon writes are recorded, how to reconstruct who approved what (apr_approvals + axis_assignment.approval_ref), governance reporting.

Each D-doc is companion content (no source-IU edit), publishable independent of authority.
