CF Access multi-aud: CF_ACCESS_AUD now accepts a comma-separated
allow-list so requests through either the void.hynesy.com or
void2-app.hynesy.com CF Access app are honoured as owner. Fails
closed; unlisted auds rejected. Adds multi-aud test.
Void 1 (CT 301) becomes legacy but stays running untouched as an
instant rollback. -alpha tag kept pending owner sign-off.

A cryptographically-verified CF Access JWT (signature vs team JWKS + audience +
email allow-list) now counts as the owner, so browser requests through the CF
tunnel don't need the owner token copied onto each device. Fails closed → owner
token remains the fallback (LAN-direct + dev/tests unaffected). Opt-in via
CF_ACCESS_TEAM_DOMAIN / CF_ACCESS_AUD / CF_ACCESS_OWNER_EMAILS.

Owner bearer token was compared with === / !==, which short-circuits on the
first differing byte and leaks token length+prefix via response timing
(security-sweep-2026-06-01.md). New timingSafeStrEqual (crypto.timingSafeEqual
with a length pre-check so it never throws on length mismatch); wired into both
owner.js and agent_auth.js.
