+### Finding F3: Empty ScopedRepos Bypasses Scope Check on Tier 2 (Medium) — Open
 
-In `policy.go`, repo-scoped capability access previously skipped checks when
-`len(agent.ScopedRepos) == 0`.
-A Tier 2 agent with empty `ScopedRepos` (nil or `[]string{}`) was previously treated as
-unrestricted rather than as having no access.
+In `policy.go`, the repo scope check is conditioned on `len(agent.ScopedRepos) > 0`.
+A Tier 2 agent with empty `ScopedRepos` (nil or `[]string{}`) is treated as
+unrestricted rather than as having no access. If an admin registers a Tier 2
+agent without explicitly setting `ScopedRepos`, it gets access to all repositories
+for repo-scoped capabilities (`repo.push`, `pr.create`, `pr.merge`, `secrets.read`).
 
-Resolved by requiring an explicit scope for repo-scoped capabilities:
-- `[]string{}` / `nil` now denies all repo-scoped access by default.
-- `[]string{"*"}` grants unrestricted repo access.
-- Pattern matching with `host-uk/*` and `host-uk/**` still applies as before.
+Potential remediation: treat empty `ScopedRepos` as no access for Tier 2 agents,
+requiring explicit `["*"]` or `["org/**"]` for unrestricted access. This is a
