Pre-launch review blocker. AdminAuth's Tier-1 fail-open fired whenever
the workspace_auth_tokens table was empty — including the window between
a hosted tenant EC2 booting and the first workspace being created. In
that window, every admin-gated route (POST /org/import, POST /workspaces,
POST /bundles/import, etc.) was reachable without a bearer, letting an
attacker pre-empt the first real user by importing a hostile workspace
into a freshly provisioned instance.
Fix: fail-open is now ONLY applied when ADMIN_TOKEN is unset (self-
hosted dev with zero auth configured). Hosted SaaS always sets
ADMIN_TOKEN at provision time, so the branch never fires in prod and
requests with no bearer get 401 even before the first token is minted.
Tier-2 / Tier-3 paths unchanged.
The old TestAdminAuth_684_FailOpen_AdminTokenSet_NoGlobalTokens test
was codifying exactly this bug (asserting 200 on fresh install with
ADMIN_TOKEN set). Renamed and flipped to
TestAdminAuth_C4_AdminTokenSet_FreshInstall_FailsClosed asserting 401.
