Records the accepted, out-of-threat-model decisions that reviewers/agents keep
re-reporting as bugs: unauthenticated peerId (host impersonation), non-constant-
time room-password compare, public server token, enumerable room IDs, and
pause-revert-not-prevent. Spells out the threat model (ephemeral, account-less
rooms of invited participants watching a video) so the "NOFIX" rationale is clear,
and distinguishes these from genuinely-deferred items (EC-10 host grace, classifier
tuning). Cross-referenced from SECURITY.md.
