Baseline test battery that pins the current auth-decision behavior so
the upcoming consolidation refactor (single bypass site in
InternalDecider.Allow) is validated against a green baseline.
Each test names one invariant; failure messages identify exactly
which property regressed. Coverage:
- Un-elevated admin cannot bypass WORM (PUT to issued/ → 403).
- Un-elevated admin cannot edit .zddc (Principal.gate() blocks).
- Elevated admin bypasses WORM (positive control).
- Elevated subtree admin writes within scope, blocked outside it.
- Strict-ancestor rule: subtree admin cannot edit own subtree's
.zddc, can edit deeper .zddc.
- Empty email never matches.
- WORM cr survives for un-elevated document_controller (create OK,
overwrite still stripped).
- project_team has read-only outside their auto-own home.
- Forward-auth /.auth/admin gates strictly on ROOT admins:.
wormbypass_test.go retained as the original repro of the live bitnest
observation (un-elevated user write succeeded under --no-auth=1).
