 /**
  * Tier access matrix — single source of truth for what each tier unlocks.

- * The tier set matches the DB CHECK constraint in migrations 001 + 011:
- *   tier IN ('free', 'analyst', 'desk')
+ * The tier set DOES NOT YET match the DB CHECK constraint. Sessions
+ * 001 + 011 wrote `tier IN ('free', 'analyst', 'desk')`. Session 12
+ * adds 'africa' here, but the constraint must be extended in a
+ * follow-up migration BEFORE the Stripe webhook can write 'africa'
+ * to users.tier — otherwise inserts will 23514 (check_violation).
  *
- * Free is the top of the funnel. Users see the grade (the hook) but the
- * reasoning + kill-condition details stay locked. Analyst opens the
- * intelligence. Desk adds engine2 (LLM) and portfolio tracking.
+ * Roadmap:
+ *   1. Manual SQL to extend the constraint (drop + re-add covering all
+ *      four tiers) — out of scope for this session per no-migration rule.
+ *   2. Stripe webhook event for the africa price ID maps to tier='africa'.
+ *   3. The frontend Pricing component shows the tier (already done here).
  *
  * `api_access` is FALSE on every tier and must stay false. VYNDR is a
  * consumer product; the proprietary engine is never exposed externally.
