📝 WalkthroughWalkthroughThe pull request adds site certificate rotation and enrollment administration. The enrollment service handles renewal requests and reserved-site seeds. The operator schedules renewal, updates identity status, and can roll gateway Deployments. Charts, API schemas, tests, and documentation are also updated. ChangesIdentity Rotation and Enrollment

Merge Risk: 🟡 Moderate · up to The current instructions can leave a site without automatic certificate renewal or a usable re-enrollment invite. Correct those procedures before merging; the remaining schema and template concerns should also be addressed. Security Architecture ReviewSecurity architecture risk: 🟡 Moderate · up to Renewal has strong identity and authorization checks. However, compromised certificates remain usable until expiry, and a trust-mode change can interrupt gateway recovery after credentials have already changed.

docs/installation/enrollment.md:202
📐 Maintainability & Code Quality | 🟡 Minor | ⚡ Quick winUpdate the
site name already enrolledtroubleshooting entry to match the new Recovery section.The Recovery bullet on Line 93 now says an enrollment admin can delete the site's enrollment, and the site then re-enrolls under the same name. Line 202 still tells the operator to "Enroll under a new site name, as the known limit in Recovery describes." That known limit no longer exists in Recovery.
Point the entry at the delete-and-reinvite procedure. Keep "a new site name" only as a fallback for users who have no enrollment-admin access.
Proposed fix
-- **Operator logs `site name already enrolled`**: an earlier attempt spent a token for this name. Enroll under a new site name, as the known limit in Recovery describes. +- **Operator logs `site name already enrolled`**: an earlier attempt spent a token for this name. An enrollment admin deletes the site's enrollment and invites it again, as Recovery describes. Without that access, enroll under a new site name.🤖 Prompt for AI Agents

Inline comments:
Review comments at @api/enrollment-v1alpha1.yaml:
- Around line 461-477: Update the `Error` schema in `enrollment-v1alpha1.yaml`
to keep `error` as a string and describe the known codes in its description or
examples, rather than constraining it with a closed enum. Preserve clients’
ability to decode unknown future error codes.
Review comments at @charts/grid-enrollment/README.md:
- Line 90: Update the hub-namespace permissions description near the hub
bootstrap instructions to list every verb granted by the Role in
ca-bootstrap-rbac.yaml, including delete on hubSite.identitySecretName and get
on hubSite.swimKeySecretName; retain the existing permissions accurately.
Review comments at @charts/grid-operator/templates/_helpers.tpl:
- Around line 139-143: Ensure the grid.id/site-name validation in
grid-operator.validateGrid runs for every grid template, including gridsite.yaml
and inferenceprovider.yaml, by including the helper in those templates; preserve
the existing fail condition and message.
Review comments at @charts/grid-operator/templates/gridsite.yaml:
- Around line 1-6: Add the grid-operator.validateGrid include to the
gridsite.yaml template after grid-operator.normalize and before the grid.id
conditional, so missing site names fail with the established validation message
during partial renders.
Review comments at @charts/praxis-gateway/tests/config_checksum_test.yaml:
- Around line 41-55: Update the first checksum test for the 10.96.0.20 backend
to assert that checksum/config equals the hash used by “a changed backend
endpoint changes the checksum.” Keep the format assertion and the second test’s
notEqual assertion so the tests verify both the baseline hash and its change.
Review comments at @enrollment/Cargo.toml:
- Around line 72-73: Update the reqwest and rustls dev-dependency configuration
in Cargo.toml so the TLS test dependencies are included only in non-FIPS test
builds, keeping ring out of the FIPS test dependency graph. Update the FIPS CI
dependency assertion to inspect dev-dependencies and verify that ring is absent.
Review comments at @enrollment/src/bootstrap.rs:
- Around line 430-432: Update the early return in ensure_seed to require both a
matching site_name and a key_sha256 matching the public key of leaf_pem. Reuse
the computed key hash when building the SeedRecord so a mismatched held seed
proceeds through re-signing with a higher generation.
Review comments at @enrollment/tests/renewal.rs:
- Line 3: Replace the `#![allow(clippy::tests_outside_test_module, ...)]`
suppression in `renewal.rs` with a reasoned `#[expect(...)]` in the existing
expectation block. Make the same change in `renewal_tls.rs`, ensuring the
expectation is not unfulfilled when built with `--features fips` and the
crate-level FIPS cfg excludes its tests.
Review comments at @operator/src/controller/grid_network.rs:
- Around line 888-896: Update the identity failure handling in `identity_status`
and the phase decision using `site_identity_status`: when identity material
cannot be read or validated and `siteSecretRef` is configured, preserve the
prior identity or report an explicit unreadable status, and ensure the phase is
not healthy. Also prevent the expiry gauge from retaining a stale last-good
value after a failed read.
Review comments at @operator/src/main.rs:
- Around line 138-148: Update GridModes::restart_for in
operator/src/controller/grid_network.rs to restart when declared.renews()
differs from self.renews(), and update a_trust_change_restarts_only_under_poll
to cover this behavior; this keeps renewal aligned with declared trust changes.
In docs/architecture/signals.md, revise lines 31–34 to remove the claim that
only the poll path reads peer trust and state that trust changes switching
renewal on or off also restart the operator. The operator/src/main.rs lines
138–148 anchor requires no direct change; it shows where renewal is started
based on the startup mode.
Review comments at @scripts/verify-helm-chart.sh:
- Line 140: Replace the PID-based `/tmp` render paths in the Helm template
commands with files created securely using `mktemp`; place CI render files in
the workspace so the artifact upload can access them after the script exits.
Update the gateway image check to read the new gateway render file and align the
workflow artifact path with the workspace render files.

Review comments at @charts/grid-operator/README.md:

that `peerTrust` defaults to `pin` only when a `GridNetwork` exists and omits
the setting. Preserve the distinction that without a `GridNetwork`,
`GridModes::WITHOUT_NETWORK` uses `spiffe` trust, so renewal runs.

- Around line 124-132: Update the “Site name held” recovery procedure to delete
the existing grid-invite-<siteName> Secret on the hub, run helm upgrade
with the site still in invites to mint a replacement token, and copy that token
to the site before re-enrolling. Preserve the existing enrollment deletion
permission guidance.
- Around line 144-147: Update the enrollment instructions to require both
`grid.peerTrust` and the site's `GridNetwork` `spec.peerTrust.mode` to be
`spiffe`. Clarify that an unset `grid.peerTrust` only selects SPIFFE before a
`GridNetwork` exists, while a network without `spec.peerTrust` defaults to pin;
retain the existing pin-mode rotation and re-enrollment guidance.
Review comments at @operator/src/crd/grid_network.rs:
- Around line 1057-1082: Replace the free-form `SiteIdentityStatus.reason`
string with an `Option<IdentityReason>` enum for the two supported failure
reasons, using explicit Serde names to preserve the existing wire values and
omitting `None` during serialization. Update the controller’s constructors and
failure check, along with affected tests, to use `Some` and `None`.

Delete the old invite Secret in the held-name recovery path.
When a redeemed invite still has grid-invite-<siteName>, the invite Job skips it and mints no replacement. The redeemed token cannot be used again, so this procedure leaves the site without a usable token to re-enroll. The expired/revoked-token step removes the Secret, but the held-name step must do so too.
Suggested fix

name. An enrollment admin runs `DELETE /v1alpha1/enrollments/<siteName>`, then

Represent identity failure reasons with an enum.
SiteIdentityStatus.reason has two valid values. The type-design rule in docs/developing/type-design.md says never use String for a fixed value set. The current schemars regex constrains the generated CRD schema, but it does not make Serde reject other strings. Use an Option<IdentityReason> with explicit Serde names to preserve the wire values and omit the field when no reason applies. Update the controller’s constructors, failure check, and tests to use Some/None.

…rk exists An operator installed before its GridNetwork started in gossip, then restarted into poll when the network appeared. The chart now passes grid.signals and grid.peerTrust, and with no GridNetwork the operator starts in those modes, so a fresh install never restarts. Signed-off-by: Sam Batschelet <sbatsche@redhat.com>
POST /v1alpha1/renewals authenticates the site by the grid certificate it presents over mutual TLS and signs a CSR for a new key under the same name. The listener requests a client certificate without requiring one, so enroll is unchanged. The record keeps the replaced key so a renewal whose response was lost can retry. A reserved name, issued by bootstrap with no token, gets its record on first renewal, and a newer bootstrap leaf supersedes it. Signed-off-by: Sam Batschelet <sbatsche@redhat.com>
…te an enrollment
A reserved name's record comes only from a seed bootstrap signs with the CA
key, so the service registers the hub without trusting the first leaf that
renews. A replaced key asking for any key but the current one means two
parties hold the identity, and the record freezes.
A grid-admin reads a site's record with GET /v1alpha1/enrollments/{siteName}
(state, key digests, notAfter) and deletes it with DELETE, which ends
renewal and releases the name. enrollment.renewal.enabled=false refuses
every renewal with 503. Error codes are a closed set in the spec, and every
503 carries Retry-After.
Signed-off-by: Sam Batschelet <sbatsche@redhat.com>
…hub identity with a mismatched key When the CA key Secret was lost, the next bootstrap minted a fresh CA and overwrote the bundle, splitting the grid across two CAs. Bootstrap now decides the CA once, before it writes anything, and mints only when no CA is distributed. It fails naming the recovery when the key is gone or does not match. Only ca.forceRegenerate starts a new grid CA. A placeholder hub identity is replaced only if unchanged since bootstrap read it, an identity whose tls.key does not match its certificate is issued again, and a hub seed that names another key is signed again. Signed-off-by: Sam Batschelet <sbatsche@redhat.com>
A 30-day leaf renewing at a third remaining expires after about 10 days without the hub. 180 days renews around day 120 and leaves about 60. A renewed leaf takes the service's lifetime when it is issued, so existing 30-day leaves move to 180 days at their first renewal. Signed-off-by: Sam Batschelet <sbatsche@redhat.com>
…he gateway after When a third of the lifetime remains, the operator presents the current certificate to the enrollment service and writes the renewed certificate and key into the same Secret. It stores the new key before sending, so a lost response retries with the key the service recorded, and rechecks soon after a renewal so the next is scheduled from the new leaf. GridNetwork status.identity reports the expiry, and an expired or unreadable identity is Degraded. Renewal follows the GridNetwork's declared peer trust on every check and is off under pin, because a pinned peer refuses a renewed leaf. The gateway loads its client certificate only at start, so after a renewal the operator rolls the gateway Deployment. The chart grants patch on that one Deployment while renewal is on. The operator also self-signs a grid CA only when both TLS Secrets are absent and never overwrites one. Signed-off-by: Sam Batschelet <sbatsche@redhat.com>
A deterministic model drives enroll, renew, lost responses, cloned keys, database restores, enrollment deletes, hub seeds, and CA key loss over a simulated clock. After every step it checks that no two keys renew one site, that a frozen site recovers through the documented steps, and that the grid CA never changes without a deliberate regeneration. Signed-off-by: Sam Batschelet <sbatsche@redhat.com>
Covers the renewal flow and recovery, the 180-day lifetime, why pin trust does not renew, the gateway roll, reading and deleting an enrollment, and turning renewal off. Signed-off-by: Sam Batschelet <sbatsche@redhat.com>
With RENEWAL_LIFETIME set, the spiffe leg issues short-lived site certificates and polls signals, then asserts that the hub and the site each renew twice with an advancing notBefore and one INFO per renewal, that both gateway mutual TLS paths and peer polls answer across every rotation, that each gateway rolls onto its current leaf, that a replaced leaf asking for a new key freezes the site, and that a grid-admin delete and a new invite re-enroll it. The pin leg asserts that renewal stays off. NET_PREFIX runs calls to LoadBalancer addresses through a rootless podman network. Signed-off-by: Sam Batschelet <sbatsche@redhat.com>

Summary
Adds automatic certificate rotation for site identities under spiffe peer trust. A site rotates its certificate for a new key before it expires, with no new invite. The grid CA does not rotate. Today a certificate lasts 30 days and is replaced by hand.
