 - PostgreSQL database;
 - optional Valkey or Redis for temporary coordination state.
 
+The executable Community boundary is recorded in
+[`docs/capability-inventory.json`](../capability-inventory.json). Only
+`implemented` denotes a delivered flow; `planned`, `gap`, and `blocked` do not
+count as ready. Resources, Prompts, background Tasks, and Load Runs are planned
+targets and are not advertised as implemented in the current version.

+The verified brownfield snapshot is recorded in
+[`docs/capability-baseline/manifest.json`](../capability-baseline/manifest.json).
+It binds the inventory, required surfaces, taxonomy, bounded manual checklist,
+and sanitized results by exact SHA-256. A full pass requires
+`implemented + automated + pass`; flaky, skipped, not-run, and manual-only
+evidence remain non-pass.
