Wire the direct caller in a post-merge follow-up.

.github/workflows/mirror.yml is the only caller. It pins mirror-reusable.yml to d55304a01b5260b0511aae0d14ed8b8770b00293 and maps only the seven existing mirror secrets.

After the caller points to the landed reusable-workflow revision, add the two R2 credential mappings. Without them, the R2 job skips the upload when enabled. R2_AGE_RECIPIENT can come from either secrets.R2_AGE_RECIPIENT or vars.R2_AGE_RECIPIENT, so only the two access credentials are unconditionally missing from this caller.

Do not pin the caller to an unstable PR-only revision. Repin it after the reusable workflow lands on a stable revision.

P2 Badge Wire the R2 job into the repository caller

The repository's actual entry point, .github/workflows/mirror.yml, still invokes the immutable old reusable SHA d55304a… and forwards only the original seven forge secrets. Consequently pushes in this repository never load this new job and cannot pass either R2 credential or the age recipient, even if the new enablement variable is configured. Update the caller pin and its explicit secret mappings as part of adding this job.

Reject dots in R2 bucket names.

This expression accepts a value such as backup.store, but Cloudflare permits only lowercase letters, digits and hyphens in R2 bucket names. The verification step therefore passes an invalid bucket and the upload fails later. Remove . from the permitted characters. (developers.cloudflare.com)

P1 Badge Preserve immutable bundles instead of overwriting the backup

For an R2 bucket without separately configured object versioning, every run overwrites the same latest.bundle.age key. After a force-push or ref deletion, the next checkout and upload replaces the only bundle with one that no longer contains the removed refs, so this implementation cannot meet the cited D303 requirement to recover from history rewrites and deleted refs. Upload each bundle under an immutable timestamp/commit key and optionally update a separate latest pointer.

Document the R2 secret mappings for callers.

The R2 paragraph does not tell callers to pass R2 secrets through secrets:. A caller that sets R2_BUNDLE_MIRROR_ENABLED but does not map the secrets gets an empty R2_KEY_ID and R2_SECRET_KEY. The mirror-r2-bundle job then skips the upload and emits only a notice. Add a caller example to this section.

R2_AGE_RECIPIENT can come from a secret or a variable. Map it only when it is held as a secret. If it is a variable, the job reads it from vars without a mapping.

 `plaintext bundle`, and uploads only the `.bundle.age` ciphertext to Cloudflare

+Callers must pass the R2 secrets explicitly in the `secrets:` block. GitHub does
+not pass caller secrets to a reusable workflow automatically. Without these
+mappings, the `mirror-r2-bundle` job skips the upload and emits only a notice.

R2_ACCESS_KEY_ID and R2_SECRET_ACCESS_KEY, and show R2_AGE_RECIPIENT in the

`git bundle`, verifies it, encrypts it client-side with `age -r`, removes the
plaintext bundle, and uploads only the `.bundle.age` ciphertext to Cloudflare
R2.

`scripts/tests/science-ci-security-test.sh` launches the assertions in
`scripts/tests/science-ci-security-test.rb`, which exercise every actual SSH
verification step with the real `ssh-keygen` fingerprint implementation. It
tests approved, tampered, absent, malformed, and unapproved keys, including
that failure cannot export a trusted SSH configuration. The same suite checks
that failure cannot export a trusted SSH configuration, plus the R2 endpoint
and `age` recipient verification gate. The same suite checks
that the Hypatia source checkout matches its resolved cache identity.
