Niklas Ye 048f4448c4 Stage 4: TerdutAlertSource
CI / test (push) Successful in 1m34s
Covers webhook Secret generation/ownership (DESIGN.md §4.5, §7), the
WebhookSecretLost fail-closed condition, and the kind-change
delete-and-recreate rotation path.

Idempotent-create here is deliberately neither adopt-on-409
(Team/service-account) nor list-and-match-by-name (TerdutDeadmanSwitch):
terdut-server shows the webhook key exactly once, at creation, and never
again, so no server-side lookup could ever recover it after a crash.
Instead the generated webhook Secret itself -- written immediately after
the POST, before status is ever touched -- is this CR's only durable
record that a create already succeeded; found with status.integrationID
still unset on a later reconcile, it's read back directly rather than
POSTing a second, orphaned integration. Found missing with
status.integrationID *set* instead, that's the already-designed
WebhookSecretLost case: fail closed, not self-healed, since the key is
genuinely gone and recreating it would rotate a live webhook URL with no
spec change to explain why.

Renaming (PATCH) never touches the key, so it's applied unconditionally
every reconcile, same as the escalation policy's whole-policy PUT. A
spec.kind change is the one case with no in-place update verb at all:
DELETE the old integration, delete the stale webhook Secret, then run the
same create path fresh -- fires a Warning event since this breaks whatever
still sends to the old URL.

Also: fakeTerdutServer grows POST/PATCH/DELETE .../integrations routes
behind a new handleIntegrationSubPath, split out of handleTeamSubPath to
stay under gocyclo's threshold; three goconst-flagged test literals
("does-not-exist", "unready") and one unparam-flagged test helper
parameter (bootstrapReadyTerdutServer's always-"default" namespace) get
shared/removed now that a fourth same-shaped caller made the repetition
concrete enough for the linter to flag.

DESIGN.md §13 gains one honest gap found while grounding this stage, not
introduced by it: no child CRD specially detects a mid-life teamRef
change; all three always resolve spec.teamRef fresh and trust the
already-stored server-side id remains valid there.

make fmt lint test build all clean; internal/controller envtest coverage
holds at 71.6%.

Niklas Ye fb9e6a38dc Stage 3: TerdutEscalationRule + TerdutDeadmanSwitch
CI / test (push) Has been cancelled
Both child CRDs resolve their own teamRef -> TerdutTeam.status via the new
shared resolveTeamAndClient helper (childref.go), never chaining up to
TerdutServer (DESIGN.md §5) -- TerdutTeam.status.serverEndpoint, added in
this same stage, is what makes that literally true.

TerdutEscalationRule: one PUT /api/teams/{id}/escalation per reconcile
(an upsert server-side, confirmed against source), resolving each "user"
target's username to a user_id via GET /api/users first and reporting
Ready: False, reason: UnknownUser if it doesn't resolve. No DELETE exists
for this resource, so its delete path PUTs an empty policy as the closest
available undo.

TerdutDeadmanSwitch: real create/update-in-place/delete, using
terdut-server v0.33.0's PUT (added specifically for this operator). No
unique-name constraint server-side, so idempotent-create here is
GET-list-and-match-by-name rather than adopt-on-409.

Extends tdclient with User/GetUserByUsername, the escalation request types
+ SetEscalation, and DeadmanSwitch + its CRUD methods. Also folds
ConditionTeamReady into the single shared ConditionReady constant, since
both were literally "Ready" and Stage 3 would otherwise have needed a
third same-valued constant.

internal/controller/terdutserver_controller_test.go's fakeTerdutServer
grows GET /api/users, PUT .../escalation, and the full dead man's switch
collection/item routes, replacing the old parseTeamPath/handleTeamByID
pair with a more general parseTeamSubPath/handleTeamSubPath dispatcher
that still covers every existing Stage 1/2 route unchanged.

make fmt lint test build all clean; envtest coverage for
internal/controller: 50.5% -> 71.7%.

Niklas Ye c9c52af2f7 Stage 2: TerdutTeam (create, mint team credential, rename/oidc-groups, delete)
CI / test (push) Successful in 1m41s
Implements ROADMAP.md Stage 2 against terdut-server's now-real
GET /api/teams?name= (TEAM-LOOKUP.md, landed in terdut-server just
before this commit) -- without it, the adopt-on-409 pattern this
controller depends on for team creation had no server-side lookup to
call, the same gap TerdutServer's own bootstrap flow hit and fixed in
Stage 1.

- api/v1alpha1: TerdutTeamSpec per DESIGN.md §4.2 (serverRef, displayName,
  oidc). status.credentialsSecretRef drops namespace for key, matching
  the fix already applied to TerdutServer's.
- internal/controller:
  - terdutteam_controller.go: resolves serverRef (same-namespace by
    default; cross-namespace gated by the target TerdutServer's
    spec.allowedTeams, DESIGN.md §4.6), waits for that TerdutServer to be
    Bootstrapped (no cross-controller RPC -- reads its
    status.credentialsSecretRef directly, DESIGN.md §5), creates the team
    and mints its team-scoped credential using the TerdutServer's
    instance-scoped one, then applies rename/oidc-groups with the
    team-scoped credential every reconcile (both are idempotent PUTs of
    the whole resource -- applied unconditionally rather than diffed
    against a stored last-applied value, same "cheap because it's small"
    reasoning §5 already gives the escalation policy's whole-policy PUT).
  - terdutteam_allowedteams.go: the §4.6 consent check in isolation from
    any client, unit-tested directly against hand-built inputs.
  - terdutteam_bootstrap.go: create-or-adopt-on-409 for the team itself
    (via TEAM-LOOKUP.md) and for its team-scoped service account (via the
    same GET-by-name+mint-new-key pattern Stage 1 already uses for the
    instance account).
  - secrets.go: extracted TerdutServer's write/read-credential-Secret
    helpers into free functions, now shared by both controllers rather
    than duplicated.
  - Finalizer deletes the team server-side (owner-gated, needs the
    team-scoped credential -- confirmed against source that an
    instance-scoped one does not satisfy requireTeamOwner, same finding
    as TEAM-LOOKUP.md's) and cleans up its credentials Secret. A team
    created but never fully reconciled to Ready (no team-scoped
    credential ever minted) is left orphaned server-side on delete -- a
    known, documented limitation (terdut-server has no delete path that
    doesn't require owner-equivalent access), not a silent gap.
- internal/tdclient: Team type, CreateTeam, GetTeamByName, RenameTeam,
  DeleteTeam, SetTeamOIDCGroups, CreateTeamServiceAccount -- matching
  terdut-server's real handlers' shapes field-for-field, same as Stage
  1's client additions.
- Tests: envtest covering the happy path, both not-ready reasons
  (ServerRefNotFound, WaitingForServer), cross-namespace allow/deny
  (default-closed and explicit All), both adopt-on-409 paths (team
  itself, team-scoped service account), and deletion. Extended the shared
  fakeTerdutServer (Stage 1) with team endpoints rather than writing a
  second, separately-drifting fake. 72.8%/30.6% coverage, 0 lint issues.

Verified locally: make fmt lint test build all clean.

Niklas Ye 1be7cf2b7f Stage 1: TerdutServer, bring-your-own bootstrap credentials
CI / test (push) Successful in 1m41s
Implements the narrowed Stage 1 scope from ROADMAP.md, against the
bootstrap-flow fix from DESIGN.md §4.1/§6 (the earlier self-registration
flow couldn't work unauthenticated against terdut-server's real
AuthMiddleware -- see that commit for the full trace).

- api/v1alpha1: TerdutServer with spec.endpoint + spec.credentialsSecretRef
  + spec.allowedTeams (image/replicas/networking/database deferred to
  Stage 5, per DESIGN.md's own narrowing). SecretKeyRef has no namespace
  field -- always the operator's own, by construction.
- internal/controller: TerdutServerReconciler implements exactly the
  bring-your-own path -- adopt spec.credentialsSecretRef if the Secret
  exists and has data under the given key, probe GET /api/version as a
  reachability check, set Ready/Bootstrapped conditions accordingly.
  Self-registration (the /api/bootstrap race) is not implemented; unset
  spec.credentialsSecretRef reports Ready: False, reason:
  CredentialsSecretRefRequired, not an attempt at a flow that would fail
  unauthenticated anyway. No finalizer: this stage creates nothing
  server-side and adopts rather than generates its Secret, so there's
  nothing to clean up on delete yet.
- internal/tdclient: minimal terdut-server API client (Version only, the
  one call this stage needs), styled after terdut-tui's own
  internal/api/client.go per terdut/CLAUDE.md's mirroring convention.
- Tests: envtest suite covering all four not-ready paths plus the happy
  path (fake terdut-server via httptest.Server, per DESIGN.md §11), and a
  focused unit suite for tdclient. 75.6%/82.4% coverage.
- Event recording uses the new events.k8s.io/v1 recorder API
  (mgr.GetEventRecorder), not the deprecated GetEventRecorderFor --
  caught by golangci-lint's staticcheck before it shipped.

Verified locally: make fmt lint test build all clean, 0 lint issues, all
specs pass.

Niklas Ye c97571c4c4 Scaffold project with Kubebuilder v4
kubebuilder init --domain ryuvia.com --repo git.ryuvia.com/niklas/terdut-operator
(--license none, no per-file header boilerplate -- terdut-server's source carries
none either). Go 1.26.0/controller-runtime v0.25.0/controller-tools v0.22.0, whatever
the current kubebuilder CLI (v4.16.0) scaffolds -- not pinned back to terdut-server's
go 1.25.9, since this is a separate module with its own toolchain.

Verified locally: build, vet, fmt all clean; `make lint` (golangci-lint, fetched into
bin/) 0 issues; `make test` (controller-gen + setup-envtest, fetched into bin/,
downloads real envtest binaries from storage.googleapis.com) passes.

Dropped kubebuilder's default .github/workflows/* -- this org runs on Gitea, not
GitHub; ci.yaml (next commit) is the only CI this repo gets.
