To gate pull requests on proven security bugs, have your coding agent verify the diff through the kernel, then add one deterministic CI step: redmirror-reflect audit. It reads the kernel's checkpoint and fails the build only when a finding is left un-grounded, using no model and no network. Every red build traces to a kernel verdict, not a guess, so there is no false-positive flood and teams keep the gate on.
redmirror-reflect init ci; it prints the pipeline step to paste, a single run: redmirror-reflect audit.redmirror-reflect audit reads the kernel's checkpoint and exits 0 (pass) or 2 (fail). No model, no network, no tokens.It is two steps in your pipeline. First, your coding agent verifies the changed files: for each suspected bug it drives RedMirror Reflection's propose-then-gate loop, and the compiled kernel either grounds the finding with a concrete, replayable attack path or sends it back to revise. Grounded outcomes are checkpointed locally to .redmirror-reflect/session.jsonl. Second, a deterministic step, redmirror-reflect audit, reads that checkpoint and sets the build's exit code. The agent step is where the thinking happens; the audit step is a dumb, reproducible check over what the kernel already decided, which is why it belongs in CI.
Security gates get ripped out when they cry wolf. In the Pixee / Black Duck 2025 DevSecOps Report, 71 to 91 percent of SAST findings are false positives and 22 percent of teams have disabled a security tool because of false-positive fatigue. This gate has nothing to flood a PR with: it reads only the kernel's checkpoint, runs no model, and makes no network call, so it cannot invent a warning. A red build is always a real, kernel-adjudicated result you can go look at.
| CI gate | What turns the build red | Noise on a PR | Risk teams disable it |
|---|---|---|---|
| Pattern SAST gate (Semgrep, SonarQube, CodeQL) | Any rule match on the diff, proven or not | High: style plus unproven warnings, many false positives | High: often set non-blocking or removed |
| LLM-review gate | Whatever the model flags this run | Variable and non-deterministic: plausible bugs it cannot back | High: output changes run to run |
RedMirror proof gate (redmirror-reflect audit) | A finding the kernel adjudicated and your agent left un-grounded | None: reads only kernel verdicts, no model at the gate | Low: deterministic, no flood |
The audit command is deterministic and takes no flags. It reads the kernel's local checkpoint and exits:
REVISE, or when a coverage cell is still pending.Because the outcome is a pure function of a checkpoint file, the same commit always produces the same verdict. No model runs at this step, so there is no run-to-run drift and no token spend on the gate.
Install and license the binary on the runner, print the step with init ci, and paste it after your agent's verify step.
# On the CI runner: install + license curl -fsSL https://dist.redmirror.io/install.sh | sh redmirror-reflect license activate <your-key> # Print the pipeline step to add redmirror-reflect init ci
init ci prints a ready-to-paste step. Run your coding agent on the diff first, then the gate:
# .github/workflows — run the agent, then gate on what it proved - name: Verify the diff # your agent verifies the changed files run: <your coding agent, headless> # Claude Code / Cursor / codex / gemini / pi ... - name: RedMirror Reflection gate run: redmirror-reflect audit # exits 2 if any finding is left un-grounded
Any CI runner works: redmirror-reflect audit is a plain shell command, so GitLab CI, CircleCI, Jenkins, and Buildkite gate on its exit code the same way. Full per-system setup is in the docs.
Use it as a required check on pull requests that touch reachable-state risk: authentication and authorization, payments and pricing, access control and multi-tenant boundaries, quotas and rate limits, and anything a coding agent generated near those. It is a strong fit precisely because it stays quiet until there is a kernel-decided reason not to. It is not a secrets scanner or a dependency-CVE scanner; keep those gates too. It also assumes a coding agent runs the verify step first: the agent is what proposes the claim the kernel then grounds, so a pipeline with no agent step has nothing for audit to check.
Run your coding agent's verify flow on the changed files, then add one deterministic step to CI: redmirror-reflect audit. The agent proposes each suspected bug and the kernel either grounds it with a concrete, replayable attack path or sends it back to revise. The audit step reads the kernel's checkpoint and fails the build if any finding was left un-grounded, so only kernel-decided results can turn the build red.
No flood. The gate reads only the kernel's checkpoint, a record of verdicts the kernel reached, never a model's guess. It uses no model and no network, so it cannot invent warnings. A clean run, whether no bugs were found or every finding was grounded, exits zero and stays silent. That is why the gate is safe to make a required check.
redmirror-reflect audit exits 2 (build fails) when a finding was raised but left un-grounded, meaning its last gate outcome was revise, or when a coverage cell is still pending. It exits 0 (build passes) when there is nothing to check, or when every finding is grounded and every coverage cell is grounded or cleared. The check is deterministic: it reads a JSONL checkpoint and runs no model.
No. The audit step reads a local checkpoint file and exits on its contents. It uses no model, no API key, no network, and no tokens. The coding agent that ran before it needs a model, but the deterministic gate that decides the build's exit code does not.
Any CI runner that can run a shell command and gate on its exit code, including GitHub Actions, GitLab CI, CircleCI, Jenkins, and Buildkite. redmirror-reflect init ci prints a ready-to-paste GitHub Actions step; on other systems, run redmirror-reflect audit as a build step and let a non-zero exit fail the job.
