-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.
-- **R's configure silently disables graphics devices when headers are missing.**
-It never fails the build, so a missing `-dev` package yields a working R whose `capabilities()` reports `cairo`, `png`, `jpeg` and `tiff` as `FALSE`.
-Installing the runtime libraries on the target system afterwards cannot bring compiled-out devices back; the binary has to be rebuilt.
-`builder/build.sh` therefore asserts `REQUIRED_CAPABILITIES` (set per Dockerfile) after `make install`.
-- **The `--with-x=no` on the Alpine images does not disable cairo.** R's bitmap and pangocairo checks run independently of `R_X11`, so `png()` and `svg()` work headless via cairo.
-- **Artifact filenames carry only the R version, not the builder image.**
-When a builder change alters the resulting binary, dedup would keep serving the stale artifact forever; set `FORCE_REBUILD` in `.crow/build.yaml` to rebuild and overwrite in place.
-- 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.
