+# Purpose and change boundary
+
+Approve a new consumer of the existing platform@coulomb.social SMTP mailbox,
+not a new mailbox, password rotation, shared namespace role or telemetry change.
+Related: CSOC-WP-0010, NK-WP-0047, CCR-2026-0035. Prepared review branch only.
+
+## Prepare fixed attended mailbox-consumer admission
+
+```task
+id: RPF-WP-0052-T01
+status: done
+priority: high
+```
+
+CCR-2026-0035 and scripts/authelia_smtp_delivery.py reuse the tested silent owner lane; exact sso/authelia-smtp-eso ServiceAccount, OpenBao audience, max15m token/no default policy. Preserve SMTP credential/version and telemetry consumer. Verify password/settings privately and SMTP AUTH without mail send; deny coding-agent direct data/metadata access; refuse different existing policy/role.
+
+## Execute attended owner admission
+
+```task
+id: RPF-WP-0052-T02
+status: wait
+priority: high
+```
+
+Founder exact approval and own interactive OpenBao platform-admin login required. Execute helper from approved owner checkout with a new mode0600 receipt. Success requires verified receipt and Warden actual child-completion outcome, not exit code alone. Never print mailbox fields/password or reuse static ESO token helpers.
+
+## Verify scoped delivery and owner handoff
+
+```task
+id: RPF-WP-0052-T03
+status: wait
+priority: high
+```
+
+NetKingdom applies dedicated service account/store/projection and checks Ready. Demonstrate correct consumer positive/other-consumer negative boundary, read-only path, credential untouched, actual package SMTP readiness. Record retained role/policy IDs and handoff to NK-WP-0047; do not claim inbox receipt from AUTH alone.
+
+Prepared evidence: ten SMTP admission tests passed; notifier/password-mount
+and password-only ESO projection parsed; server dry-run accepted package
+resources. Dedicated SMTP egress is required and drafted. Native runtime
+credential validation, admitted consumer and inbox receipt remain pending.
+No live activation or mail sent.
