docs(rfc-ws-6): v1.3 amendment — listener queueing, invariant cleanup, failure-UX
Five refinements from the 2026-05-07 architectural review:
- Q1: TriggerPersonIdentityMatchOnFormSubmit moves to queued; sync-chain reduced to ApplyBindings only; queued-listener gating invariant; sync-chain deadline wrapper.
- Q2: Failsafe pad in TriggerPersonIdentityMatch removed in favour of strict invariant + throw; RequiresIdentityKeyBinding unconditional for event_registration; FormSubmissionResource.identity_match=null contract for non-person purposes.
- Q3: Three failure-UX additions (GlitchTip alert, custom exception hierarchy + error_code, BACKLOG entries for partial-success and schema-drift).
Spine unchanged: pre-publish guards, strict service / log-and-swallow listener, two-transaction pattern, single identity-key per target_entity.
Refs: dev-docs/RFC-WS-6.md (now v1.3), dev-docs/ARCH-BINDINGS.md (now v1.1), dev-docs/BACKLOG.md (PARTIAL-BINDING-SUCCESS, FORM-SCHEMA-DRIFT-DETECTION added)
