Conversation
Grants id-token + attestations at the caller jobs so the reusable workflows can keyless-sign + attest this pack's images and chart once the signing-enabled reusable workflows ship under @v1. Permissions only; inert until then.

What
Grants the
id-token+attestationspermissions the reusablepack-build-image/pack-releaseworkflows need so this pack's containerimages and Helm chart get keyless-signed + attested (provenance + SBOM) once the
signing-enabled reusable workflows ship under
@v1.Permissions only - no
uses:ref change (stays@v1), no chart version bump, noother behavior change.
Why it's blocked
@v1does not include signing yet; that's nebari-dev/.github#46. Until #46merges and
v1is retagged, these permission grants are inert (unused, harmless).Merge order: #46 →
v1retag → this PR.Validated
The full signing path (these exact caller permissions + the reusable workflows)
was already exercised end-to-end against this pack from a throwaway test branch:
all 4 images signed on both ghcr and quay, the chart
.tgzsigned, everythingcosign verify-ed successfully. See the validation comment onnebari-dev/.github#46. The canonical OCI chart signing is nebari-dev/helm-repository#64.
