+# Phase 6 Plan 03: Web Chat Human Verification Summary
+
+**End-to-end web chat verified live: WebSocket messaging, conversation persistence, typing indicators, markdown rendering, and RBAC scoping all confirmed working across all three portal roles.**
+
+## Performance
+
+- **Duration:** Verification (human-gated checkpoint)
+- **Started:** 2026-03-25
+- **Completed:** 2026-03-25
+- **Tasks:** 1 (human-verify checkpoint)
+- **Files modified:** 0
+
+## Accomplishments
+
+- Human reviewer confirmed all 5 test scenarios from the verification checklist
+- End-to-end flow verified: user sends message via WebSocket, receives LLM response
+- Conversation history confirmed to persist and reload correctly on page revisit
+- Typing indicator confirmed visible during response generation
+- Markdown rendering confirmed correct in agent responses (bold, lists, code blocks)
+- RBAC confirmed: customer_operator can chat but admin-only nav items remain hidden
+- Platform admin confirmed able to chat with agents across tenants
+
+## Task Commits
+
+This plan contained a single human-verify checkpoint task — no code changes were required.
+
+**Plan metadata:** (docs commit — see final_commit below)
+
+## Files Created/Modified
+
+None — this plan is a verification gate only. All implementation was completed in Plans 01 and 02.
+
+## Decisions Made
+
+All CHAT requirements (CHAT-01 through CHAT-05) verified by live human testing before Phase 6 marked complete. No deviations from the plan were needed.
+
+## Deviations from Plan
+
+None — plan executed exactly as written. Human reviewer approved all verification scenarios.
+
+## Issues Encountered
+
+None.
+
+## User Setup Required
+
+None - no external service configuration required.
+
+## Next Phase Readiness
+
+Phase 6 is complete. The web chat feature is production-ready:
+- WebSocket-based real-time chat integrated with the full agent pipeline
+- Conversation history persisted in PostgreSQL
+- Markdown rendering and typing indicators fully functional
+- RBAC enforced across all three roles (platform_admin, customer_admin, customer_operator)
+
+No blockers. Phase 6 is the final planned phase — v1.0 feature set is complete.
+
+## Self-Check: PASSED
+
+- `06-03-SUMMARY.md` — FOUND
+- STATE.md updated (progress recalculated: 25/25, 100%)
+- ROADMAP.md updated (Phase 6 marked Complete, 3/3 summaries)
+- Metrics recorded for phase 06-web-chat plan 03
