From an approval click to a merged pull request — rechecking file blobs and base before merging, the missing server route that left a card spinning, recording the merge first, separating the response from sync watching after a CloudFront 504, and replacing a stale AI answer with a code-written sentence.

From a chat request to an opened pull request — verifying GitHub App install callbacks, deciding between PR and kubectl per resource, steering the LLM with ModelRetry and a one-line history memo instead of prompts, code-chosen edits for plain YAML and Kustomize, and render comparison against an expected result.
