00:00:00.000 — Penguin Code. A genuine built-in agent session in a local demo, edited for time.

00:00:03.000 — The user asks Penguin to find the shared retry path, fix duplicate charging, and run the regressions.

00:00:10.000 — Repository context is retrieved. The recorded interface shows six candidates.

00:00:17.000 — Penguin identifies the shared retry function and runs the test. The first command is marked failed.

00:00:23.000 — The actual retry.js file changes: claim the attempt before charging, then update its status.

00:00:32.000 — The recorded summary reports two of two regression tests passing. The fixture uses no real payments.

00:00:37.000 — Inspect the diff. Review the checks. Keep control. A local demo with two regression tests.
