Early Release Guard vs. AI Code Review
Find and fix bugs beyond the Pull Request.
Code Reviewed. Still shipping bugs?
An API changes its response format. A consuming service still expects the old one. The Pull Request can pass review while the product workflow breaks.
Early investigates beyond one Pull Request.
Give QA the power to find and fix bugs.
Early finds and fixes bugs across your product and dependent projects. Engineers review the fixes and control the merge.
Compare scope and fixes.

Find the bug. Deliver the fix.
Early investigates selected product code and configured dependencies across recurring analysis windows.
Authorize a supported repair. Early implements the fix and adds tests. Engineers review, refine, and validate the Pull Request instead of starting the repair from scratch. Your team controls the merge.
See a real finding and fix
See the findings. Inspect the Fix PRs.
Two concrete examples of Early's work, from a security defect to a saved-state bug.
PHP2Shell: a security defect, then a Fix PR
A historical replay flagged the unsafe backtrace lifetime. Early then created a Fix PR on the vulnerable revision.
Explore the PHP2Shell casePydantic AI: preserve saved agent state
Early found a saved-state bug and created a Fix PR with a state-preservation test. Engineers can inspect the change and test.

Less bug investigation. Less repair work.
Common questions
Does Early replace our code reviewer?
No. Keep your code-review process. Early adds recurring bug analysis and repair across your selected development and release windows.
Can Early find bugs that are not regressions?
Yes. Early can find general defects, including existing bugs, as well as regressions relative to an approved baseline. A baseline helps identify changes; it does not prove the original behavior was correct.
How do we know Early is worth adding?
Early finds and fixes bugs across your product and dependent projects after merge, beyond a single Pull Request. Measure its value through bugs caught before release, the quality of the fixes, and engineering time saved on investigation and repair.
Who initiates fixes and controls the merge?
An authorized user initiates repair for an eligible finding. Early implements the fix and opens a draft Pull Request with tests. Engineers review, amend, validate, and control the merge.
