feat(renovate): track the Keycloak operator (the real Keycloak version), never auto-merge it
The Keycloak CR has no spec.image, so the operator's RELATED_IMAGE_KEYCLOAK picks the server image; the three keycloak-k8s-resources release URLs in platform/keycloak/kustomization.yaml are therefore THE Keycloak version, and Renovate could not see them (no `# renovate:` marker). They now carry markers under one depName (one branch, groupName keycloak-operator), with a packageRule: automerge false, labels needs-review + blast-radius; majors still wait on the dashboard. The untagged quay.io/keycloak/keycloak in catalog/keycloak.yaml renders apps/wave-1/keycloak.yaml, which no kustomization lists. It is pinned to the operator's 26.0.6 as documentation, re-rendered, and Renovate is disabled for that image so it cannot raise PRs against a file nothing deploys. The render is kept (not deleted): it is the fixture for apps/wave-1/tests/app-slis.test.yaml's keycloak SLI rule tests. README: an "Upgrading Keycloak" section — an operator bump must be checked against passkey-reconciler.yaml's 26.0.6 Admin API assumptions. Co-Authored-By: Claude Opus 5.5 <[email protected]> |

fix(keycloak-passkey): bind only on git's say-so; protect real sub-flows; screen the requirement PUT by body id
Review findings on the passkey reconciler, fixed:
1. HIGH - the bind was automatic and rollback did not stick. A git-declared switch,
`bind-browser-flow` in passkey-desired-state.yaml, now decides whether pass 3 may
PUT browserFlow. Default "false": build + verify the candidate (or reuse a verified
one), log WOULD BIND <alias>, never touch the binding - including after an earlier
bind, so an operator's rollback sticks, and a hand-edited bound candidate is left
alone rather than shadowed by an -r2 build. "true" binds as before. The renderer
carries the one hand-edited line through and --check refuses anything but the
quoted strings "true"/"false". --no-bind can only narrow it.
2. HIGH - the protected-subtree guard read `alias` on sub-flow rows. Keycloak 26.0.6
AuthenticationManagementResource.recurseExecutions sets displayName =
flowRef.getAlias() and flowId on a sub-flow row and never sets alias (alias is the
CONFIG alias on authenticator rows), so the protected set was only the top-level
alias. Sub-flows are now named by displayName (getFlows() lists top-level flows
only, so flowId cannot be resolved through it); a sub-flow row without one leaves
the subtree undetermined and the flow pass fail-closed. The selftest stub now
returns 26.0.6-shaped rows, and a real run is asserted to refuse writes into
browser-mfa-forms and browser-mfa-conditional-otp.
3. MEDIUM - PUT /flows/{alias}/executions was screened on the path alias only, but
updateExecutions resolves the execution realm-wide by body id. body.id is now
screened against the protected ids AND required to be in the tree this run is
building (recorded from the build's own readback); the config POST is held to the
same build scope; and the body may carry only id/requirement/priority (the same
handler renames any flow named by flowId).
4. Stale "audit-only" docs rewritten (platform-config kustomization, chainsaw test,
desired-state header and its renderer template, README) to describe what ships.
5. backoffLimit 0 (a retried deterministic build failure burns the candidate-alias
budget); the stale "Renovate does not manage image: tags" comment corrected and the
image pinned by index digest.
6. The ~160-line header duplicated in the YAML and the script is now kept once, in the
script, with a short pointer above it.
Selftest: 259 assertions (was 216). mutations.py: 40 injected regressions (was 30),
including one per finding above, all caught.

feat(keycloak): reconcile the passkey realm config via GitOps, the browser flow blue/green
PR #72 declared the WebAuthn passwordless policy and a restructured browser-mfa flow in the realm import. That declaration could not take effect: a KeycloakRealmImport is a ONE-SHOT, and prod's reads Done=True / Started=False, so every realm-level field and flow declared after the first import is inert -- in git, applied by Flux, reported Ready, reaching the realm never. Merging it changed nothing about how anyone logs in, and nothing anywhere said so. Same failure class as the 2026-09-06 client-secret incident, third field over. A SIBLING reconciler converges all three declared things every 15 minutes. It is a sibling, not a second pass of client-secret-reconciler.yaml, so that reconciler's allow-list -- and its guarantee that prod's real user and the media-users / platform-admins / viewers groups are structurally unreachable -- stays literally true. Its selftest still passes unchanged. pass 1 webAuthnPolicyPasswordless* -- strict read-modify-write of GET/PUT /admin/realms/homelab, readback-verified. pass 2 webauthn-register-passwordless -- strict read-modify-write of ONE literally-named alias; enabled, defaultAction false so enrolment stays opt-in. pass 3 the browser flow -- BLUE/GREEN. PASS 3 NEVER MUTATES THE FLOW USERS ARE LOGGING IN THROUGH. Converging a five-flow, ten-execution tree needs create-subflow, create-execution, set-requirement and bind-config as SEPARATE untransacted calls; doing that to the BOUND flow means a run dying between them leaves a half-built login path for every SSO app and kubectl, and this repo has had a total SSO outage from a realm change. So instead: 1. BUILD under a NEW, unused alias (declared alias + a hash of the desired shape, applied to EVERY alias in the tree -- reusing browser-mfa-forms would mean writing INTO the bound tree). A failure leaves an orphaned, unbound flow and zero user-visible effect. 2. VERIFY by readback -- levels, ordering, authenticators, requirements, and the conditional-OTP config CONTENTS -- before anything is bound, so the regression that once 403'd every platform-admin is caught BEFORE it bites. 3. BIND with ONE atomic PUT setting browserFlow. 4. ROLLBACK is one write; no DELETE exists anywhere in the allow-list, so the old flow survives as the rollback target. The widened allow-list is made safe structurally. It cannot say "but not the bound flow" -- its write entries are alias-parameterised -- so a second guard screens every write against the live browserFlow's WHOLE subtree (sub-flow aliases and execution ids) before a socket opens, FAIL-CLOSED until that binding has been read. The create-flow endpoint carries no alias in its path, so it is screened on its request BODY; the selftest caught that it otherwise escaped the guard. Idempotence is load-bearing: a rebuild-and-reflip every 15 minutes would churn the login path on a schedule. The bound flow is compared STRUCTURALLY and a match produces zero writes and no new flow. Sub-flow and config ALIASES are deliberately not compared -- a built flow carries a hash suffix, so comparing labels would make it permanently unrecognisable as converged. Single source of truth: the desired state is GENERATED from the realm import by ci/render-keycloak-passkey-policy.py and gated with --check, so the RP ID -- baked into every credential at enrolment and never re-keyable -- is declared once. The pod keeps automountServiceAccountToken: false and reads a mounted ConfigMap, so no rbac.yaml is added anywhere. Read from Keycloak 26.0.6 source before being relied on: updateRealm (DefaultExportImportManager 725-894) makes no getUsers/getClients/getGroups/ getRoles/getRequiredActions/getAuthenticationFlows call; it DOES read getBrowserFlow(), which is what makes the atomic bind possible and why the policy write pins it; the passwordless policy is applied all-or-nothing only when RpEntityName is non-empty, with defaults substituted for omitted keys; and updateExecutions compares rep.getPriority(), so a body omitting `priority` would silently reshuffle the whole execution order. Gate coverage: a new whole-repo L0 check extracts the script and runs its --selftest (216 assertions, including a build killed at four different points each asserting the old flow is still bound and the bound subtree was never written), plus mutations.py (30 injected regressions, all caught) proving the selftest can fail. An earlier iteration of this work only AUDITED the flow and left the restructure manual; decisions/2026-10-18-keycloak-passkey-reconciler.md records that design and why it was reconsidered.

feat(keycloak): declare passkey (WebAuthn passwordless) login for the homelab realm
Adds the realm's WebAuthn Passwordless policy and restructures the browser-mfa
flow so a passkey is an ALTERNATIVE beside the password form. Additive and
optional by design: this IdP gates every SSO app plus kubectl, so a mandatory
passkey flow that misfires is a total lock-out. Enrolment is not forced.
Policy: RP ID is ${BASE_DOMAIN} (not the keycloak host) because a passkey's RP ID
is fixed at enrolment and must not be bound to a name that can move; resident key
required (a non-discoverable credential is a second factor, not a passkey); user
verification required (without it, possession alone is a complete login).
Flow: auth-username-password-form is split into auth-username-form +
auth-password-form, because the server must know who is logging in before it can
decide whether a passkey exists. Conditional OTP for platform-admins is relocated
intact onto the password branch only — a UV-required passkey is already two
phishing-resistant factors.
No requiredActions block is declared, deliberately: Keycloak 26.0.6 treats
requiredActions as REPLACE not merge, so declaring one would delete the default
set including CONFIGURE_TOTP and lock every platform-admin out of the OTP step
this flow still enforces. webauthn-register-passwordless is already registered
enabled-but-not-default by Keycloak's own defaults.
UNAPPLIED: the realm import is a one-shot resting at Done=True/Started=False, so
this reaches the live realm never. See the handoff entry and the README section.

docs(keycloak): record the URL-reconciliation decisions
Records K1-K9: extend-vs-sibling and why, the generated+gated desired state, verbatim token pass-through, per-pass fail-closed, order-insensitivity, unmanaged-means-untouched, public clients' URLs managed, one alert pair not two, and the mutation harness. Also records a process note: my first pass reported three false findings (reconciler absent from main, import not templated, BASE_DOMAIN dead) because I diffed against origin/main -- origin is dev's Gitea, stale at |
