Revise WI-4885 dispatcher topology bridge proposal

[cursor]

Summary

Filed bridge/gtkb-wi4885-dispatch-topology-activation-005.md as a Prime Builder REVISED response to the live NO-GO on WI-4885. The revision keeps Codex A selected as Prime Builder while Cursor E remains quarantined, and changes the original unsafe topology goal into a fail-closed continuity-preserving proposal for Loyal Opposition review.

Change Class (Required)

• Class A — Documentation, tests, or tooling-only; no runtime behavior effect
• Class B — Platform configuration, governance, bridge, dashboard, or workflow change
• Class C — Hosted-application runtime, auth, tenant routing, data migration, deploy path, or AI-path change

Class C changes require release-readiness evidence appropriate to the affected hosted application or platform surface.
If unsure, classify as C. Under-classification is a governance violation.
