## What this PR does A tapped (community-connected) repository followed a mutable OCI tag: the Flux `OCIRepository` carried only `spec.ref.tag` with a 5-minute interval, so whoever controlled the tag controlled what ran in the management cluster within that interval, down to the HelmReleases of already-running tenant application instances. Fixes #4979. A tap is now pinned to a digest. `cozypkg tap` and the connect API accept an explicit `oci://host/org/repo@sha256:...` reference; a tag reference is resolved and pinned to its digest by the tap materializer once the artifact for the current spec generation is ready, from the digest Flux reports in `status.artifact.revision`, with the tag kept informational. A tap connected before this change is pinned to its current digest on the first reconcile after upgrade, and a re-connect to a new tag waits for source-controller to re-resolve before pinning, so a stale revision is never pinned. Moving the tag upstream no longer changes anything in the cluster; an explicit re-connect moves the pin. Connect also accepts an optional keyless cosign verification policy (`--certificate-identity` / `--certificate-oidc-issuer` on the CLI, `spec.verify` on the API), anchored to an exact identity so a superstring cannot match, and preserves it, and the pull secret, across repeat connects rather than silently dropping them. With those flags the CLI verifies the signature at tap time and pins the verified digest before pulling, so the content it applies is what a trusted identity signed; it fails closed if the verified digest cannot be determined. ### Screenshots Not applicable: no UI changes. ### Downstream repositories I walked the trigger map against the diff. The change is confined to `cozypkg`, the `Tap` aggregated API (a virtual, cluster-scoped resource with no CRD), the tap materializer, and the community-index docs. It does not touch `packages/apps`, `packages/core/platform/values.yaml`, installer values, platform variants/components, release assets, `ApplicationDefinition` semantics, the `hack/` make targets, or the commit convention, so the provider, ansible, ccp and external-apps paths are not reached. One path is arguable and needs a human decision, so I have left every box unticked rather than tick or dismiss it: - `cozystack/website` — `cozypkg tap` gains flags and digest-pinning behaviour. The marketplace tap flow is new and I am not sure it has a reference page on the site yet, so whether a docs follow-up is warranted (and where) is a maintainer call. - [ ] No downstream repository is affected by this change - [ ] [cozystack/website](https://github.com/cozystack/website) - follow-up: - [ ] [cozystack/terraform-provider-cozystack](https://github.com/cozystack/terraform-provider-cozystack) - follow-up: - [ ] [cozystack/ansible-cozystack](https://github.com/cozystack/ansible-cozystack) - follow-up: - [ ] [cozystack/ccp](https://github.com/cozystack/ccp) - follow-up: - [ ] [cozystack/talm](https://github.com/cozystack/talm) - follow-up: - [ ] [cozystack/cozyhr](https://github.com/cozystack/cozyhr) - follow-up: - [ ] [cozystack/cozy-proxy](https://github.com/cozystack/cozy-proxy) - follow-up: - [ ] [cozystack/cozystack-telemetry-server](https://github.com/cozystack/cozystack-telemetry-server) - follow-up: - [ ] [cozystack/external-apps-example](https://github.com/cozystack/external-apps-example) - follow-up: - [ ] [cozystack/examples](https://github.com/cozystack/examples) - follow-up: - [ ] [cozystack/community](https://github.com/cozystack/community) - follow-up: ### Release note ```release-note fix(marketplace): a tapped repository is pinned to a digest instead of following a mutable tag, so moving the tag upstream no longer changes what runs in the cluster; connect accepts oci://...@sha256:... and an optional keyless cosign verify policy (anchored to an exact identity and preserved across re-connects), and with verify flags the CLI verifies the signature and pins the verified digest at tap time. ``` <!-- This is an auto-generated comment: release notes by coderabbit.ai --> <!-- coderabbit-ai-generated:v1 --> ## Summary by CodeRabbit - **New Features** - OCI repositories can be connected using a SHA-256 digest, with or without a tag. Tag-based sources are pinned to the resolved artifact digest. - Optional Cosign keyless verification is available during connection using certificate identity and OIDC issuer details. - Reconnecting preserves existing verification and pull-credential settings when replacement values aren’t provided. - **Bug Fixes** - Reconnecting with a new tag clears previous operator-managed pins so the requested tag can resolve to its current artifact. - **Documentation** - Clarified tag pinning, signature verification, and where tapped app charts run. <!-- end of auto-generated comment: release notes by coderabbit.ai -->
