+# Backlog
+
+Date: 2026-05-28
+
+This file captures the narrow optional product-module extraction backlog from the core-pruning slice. It is not the live global backlog. For current operator/deploy backlog truth, use `docs/improvement-plan/OPERATOR-CHECKLIST.md` and `docs/improvement-plan/PROGRESS.md`; for CDN #51/A7/B2 specifically, use `docs/ops/asset-cdn.md`.
+
+## Optional Product Module Extraction
+
+Status: backlogged.
+
+Decision: keep optional Product Core surfaces in the repository for now. Forms and Surveys are excluded because they were selected for removal, not extraction.
+
+Scope parked here:
+
+- Workflow Engine
+- Knowledge Base and Widgets
+- Portals and Sites
+- Email Marketing
+- Analytics and Metrics
+- Notifications UI and flows
+- AI, Prompt Builder, and MCP surfaces
+
+Why this is parked: these modules are useful boilerplate surfaces, but they increase route inventory, bundle manifest size, schema surface, worker ownership, i18n surface, and agent onboarding complexity.
+
+Revisit when one of these triggers happens:
+
+- route manifest size becomes the main deploy or runtime cost;
+- a plugin/module registration system is ready;
+- the product decides which optional modules belong in the default starter;
+- a customer-facing template needs a smaller core distribution.
+
+Acceptance criteria for future extraction:
+
+- each extracted module has a feature manifest and ownership doc;
+- routes register through a module/plugin boundary instead of unconditional route discovery;
+- DB schema, queue jobs, workers, i18n keys, permissions, and seeds have clear module ownership;
+- disabled modules do not ship route or bundle surface by default;
+- verification gates cover enabled and disabled module states.
