covers added lines from every non-merge commit between the resolved base ref and

Scan each outgoing commit when the push scan protects remote history.
An agent commit in the protected shim path already runs the commit-time scan, so the original agent-created commit scenario does not apply to the normal path. However, a credential can enter the outgoing history through a human or non-shim commit, an earlier commit, or AGENTFLARE_GIT_ALLOW_SECRETS=1. If a later commit removes it, the current net-range push scan can pass while the earlier commit is published.
If push scanning must cover all commits sent to the remote, resolve the base ref separately and scan the added lines from git log --no-merges --patch --format= <base>..HEAD. Keep scope checking on the existing <base>...HEAD range. run_in_lines_bounded and added_lines_by_path already provide the required bounded execution and diff parsing. Update the removal-commit test to expect denial.

Agent-driven commits and pushes in tracked repositories now scan added diff lines with the existing
secret_scan::check_fieldsdetector before git runs. Commits cover staged and unstaged changes; pushes scan net added lines in the upstream range or remote merge-base range. Denials name the file and rule with redacted diagnostics, and diff failures fail closed.AGENTFLARE_GIT_ALLOW_SECRETS=1permits deliberate fixtures with an audit entry while preserving the other guards. The existing whole-shim bypass remains available. Human and untracked-repository invocations retain their existing behavior.Review fixes in
