Live-stack smoke caught this: every state-changing endpoint emitted an audit event, the INSERT rolled back with invalid input syntax for type inet: \"[::1]\", and the user-facing operation kept working — so audit_log stayed silently empty.

Fixes:

  • Use net.SplitHostPort which returns IPv6 hosts without brackets.
  • Add stripBrackets() as belt-and-braces for X-Forwarded-For headers that wrap the IP themselves.

When a client connects over IPv6 loopback, net/http's RemoteAddr is
'[::1]:port'. The previous clientIP() returned '[::1]' (brackets and
all) which Postgres's INET type rejects with
'invalid input syntax for type inet: "[::1]" (SQLSTATE 22P02)'.

Live local-smoke caught this — every state-changing endpoint emitted
the audit event, the INSERT rolled back, and a warning landed in the
log. The user-facing operation succeeded so the caller never noticed,
but audit_log stayed empty.

Fix:
  - Use net.SplitHostPort which returns IPv6 hosts without brackets.
  - Add stripBrackets() as a belt-and-braces for X-Forwarded-For
    headers that wrap the IP themselves (some proxies do).
