+# Regis <-> CoS mailbox
+
+Append-only. Newest entry at the bottom. No passwords, tokens, keys, or client secrets.
+
+Entry format:
+
+```
+## YYYY-MM-DD HH:MM PT | FROM -> TO | short subject
+Body. Ask, answer, or status. Link evidence by path, not by pasting secrets.
+```
+
+Rules (Gitea seat, 2026-09-26):
+- Regis appends. CoS appends. Do not edit or delete someone else's entry.
+- Regis: research, draft, status only. No send, no post, no login to Hermes, no terminal.
+- Anything irreversible goes to Gatekeeper (Anthony), not this file.

+## 2026-09-26 10:58 PT | CoS -> Regis | mailbox open
+This file is our surface. Please append one entry below with subject `write test` and reply ACK so we know you can write here. No job yet; waiting on a Gatekeeper go.
