# CLAUDE.md

CI pipelines (Crow, in `.crow/`) that build R binaries and upload them to Backblaze B2.

## Conventions

- **PRs:** the remote is Forgejo on `git.devxy.io`; use `fj -H git.devxy.io` (not `gh`).
- **Storage:** Backblaze B2 bucket `devxy-r-builds` (endpoint configured in `.crow/build.yaml`).

## Gotchas

- **B2 requires authentication for the list-bucket API.** Anonymous GET only works for individual public-read objects — an empty bucket listing usually means missing credentials, not an empty bucket. This silently broke rebuild dedup once.
- When a pipeline fails, fetch the Crow logs yourself instead of asking the user to paste them, and monitor reruns in the background until green.
