## What this PR does Adds an engine-agnostic controller that publishes a key-free `<release>.tenant-ca` Secret (only `ca.crt`) for a managed application, so a tenant can verify the application's TLS without ever seeing a private key. The source is declared, not guessed: a chart renders a namespaced `TenantProjection` sentinel (group `internal.cozystack.io`) naming the CA Secret to lift; the controller watches the sentinel, extracts `ca.crt`, and writes the projection owner-referenced to the sentinel, so garbage collection is native. The projection carries the `internal.cozystack.io/tenant-ca` label the lineage webhook turns into tenant visibility. Postgres is the first consumer. The trust boundary is RBAC: no tenant role grants any verb on `internal.cozystack.io`, so a tenant cannot forge a sentinel. A companion `ValidatingAdmissionPolicy` that pins the writer to helm-controller ships separately as defence in depth. This is the controller-and-CRD slice, split out from #3299 for focused review. It is the only piece required for the feature to work; the render-time helper, the writer policy, the capability-gate, and the release-prefix validation land as their own PRs. ### Downstream repositories Walked the trigger map against the diff. This adds an internal CRD and controller and a sentinel to the Postgres chart; no app is added or renamed and no `values.schema.json` changes, so the typed provider and Ansible are unaffected. The one to confirm is the Postgres README edit — if the website mirrors it, it needs a refresh. - [ ] No downstream repository is affected by this change - [ ] [cozystack/website](https://github.com/cozystack/website) - follow-up: ### Release note ```release-note feat(cozystack-controller): publish a key-free per-application CA trust anchor (`<release>.tenant-ca`) that tenants read to verify managed-application TLS, declared through a new `TenantProjection` CRD. Postgres is the first consumer. ``` <!-- This is an auto-generated comment: release notes by coderabbit.ai --> ## Summary by CodeRabbit * **New Features** * Added tenant-facing CA certificate projections for PostgreSQL deployments. * Tenant secrets now provide only the CA certificate, excluding private keys. * Added support for configuring and monitoring tenant CA projections. * **Documentation** * Updated PostgreSQL TLS instructions to retrieve certificates through tenant secrets. * **Bug Fixes** * Improved protection against invalid certificates, secret collisions, and accidental exposure of private key material. * Added validation to ensure projected certificates remain synchronized with their sources. <!-- end of auto-generated comment: release notes by coderabbit.ai -->
