⚠ Remove Progressing condition from ClusterObjectSet

[perdasilva]

Description

Follow up to #2942 and step 2 in simplifying the ClusterObjectSet status conditions ahead of introducing the ClusterObjectDeployment API. The Progressing will be moved over there.

Removes the Progressing status condition type from the experimental ClusterObjectSet (COS) CRD. Progress/retry/block/deadline semantics now live at the ClusterExtension (CE) layer; COS exposes only revision state (Available) and a done latch (status.completedAt). This continues the direction of #2942 (completedAt in lieu of the COS Succeeded condition).

Scope: experimental channel only — COS is experimental-only. No standard-channel CRD/manifest changes.

What changed

• COS controller now expresses all rollout state through a single Available condition with an expanded reason set, and never writes Progressing. Available reports the state of the revision — True = all objects are at the desired state, False = one or more objects are not (whether still rolling out or in error), and Unknown is the initial state before the first reconciliation evaluates the revision (i.e. never written explicitly by the controller):

  status	reason	meaning
  True	ProbesSucceeded	rolled out, all probes pass (paired with completedAt)
  False	ProbeFailure	rolling out, objects failing probes
  False	RollingOut	rolling out, not yet complete
  False	Reconciling	reconcile error prevented observing probes (was Retrying)
  False	Blocked	terminal error, manual intervention required
  False	ProgressDeadlineExceeded	deadline exceeded before rollout
  False	Archived	archived / torn down

• operator-controller now reconstructs the CE Progressing condition from COS Available + completedAt (progressingFromAvailable), instead of mirroring COS Progressing. The CE Progressing/Installed public contract is preserved byte-compatibly on status/reason:

  input	CE Progressing
  completedAt set	True/Succeeded
  Available False/Blocked	False/Blocked
  Available False/ProgressDeadlineExceeded	False/ProgressDeadlineExceeded
  Available False/Reconciling	True/Retrying
  otherwise (ProbeFailure/RollingOut)	True/RollingOut

  The reconstruction keys on the Available reason, not its status, so the Unknown→False change above does not affect the CE contract; archived revisions are excluded from reconstruction entirely.

• Removed the COS Progressing type constant and printcolumn; regenerated CRDs, manifests, applyconfigurations, and API reference docs.

• Updated the ClusterObjectSetIsArchived e2e step to wait on Available=False/Archived.

Accepted deviations

• Single reason surfaced: Available carries one reason at a time, so when several conditions apply (e.g. a revision that is blocked or past its deadline while still rolling out), the most significant blocking reason is reported rather than a separate probe/rollout value. Intentional — block/deadline take precedence in the single remaining condition.
• Reconstructed CE Progressing messages are best-effort (reused from Available); reason + status match the frozen contract, messages may differ.

Test plan

• make test-unit — passing (incl. new progressingFromAvailable, determineFailureReason, and COS reconcile tests for first-reconcile retry and deadline-wins-over-probe-failure).
• make verify / make lint — clean, generated code in sync.
• Standard-channel CRDs/manifests confirmed unchanged.

Summary by CodeRabbit

• Changes
  • ClusterObjectSet status now uses the Available condition to report rollout progress, probe failures, reconciliation errors, deadline expiry, and archival.
  • The separate Progressing status column has been removed. Rollout completion time is reported separately.
  • ClusterExtension progress status continues to reflect revision availability, with clearer reporting of failures when no bundle is installed.

📝 Walkthrough

Walkthrough

ClusterObjectSet reconciliation now records rollout and health states through the Available condition. The Progressing printer column and condition declaration were removed. The operator controller derives Progressing status from revision Available conditions.

Layer / File(s)	Summary
Available condition contract api/v1/clusterobjectset_types.go, applyconfigurations/api/v1/clusterobjectsetstatus.go, helm/olmv1/base/operator-controller/crd/experimental/*, manifests/experimental*.yaml	The API documentation and CRD schemas describe rollout and health outcomes through Available, remove the Progressing printer column, and identify status.completedAt as the rollout completion record.
Object set reconciliation conditions internal/object-controller/controllers/clusterobjectset_controller.go, internal/object-controller/controllers/clusterobjectset_controller_test.go, test/e2e/steps/steps.go, test/e2e/features/*.feature	Reconciliation writes retry, rollout, probe, deadline, blocking, and archive states to Available. Tests check condition values, including deadline precedence over probe failures.
Operator status projection internal/operator-controller/controllers/boxcutter_reconcile_steps.go, internal/operator-controller/controllers/common_controller.go, internal/operator-controller/controllers/common_controller_test.go	The operator controller copies revision Available conditions into status, derives Progressing from Available, and detects reconciliation failures from the latest rolling revision. Tests cover the mappings and failure selection.

Loading

Merge Risk: 🔵 Low · up to af3e0

A ClusterExtension can briefly show a stale or missing Progressing status before its first revision reconcile. Existing ClusterObjectSet resources may also keep the old Progressing condition. Both effects are status-only and bounded, so the change is mergeable, but the missing-condition fix should be applied.

Security Architecture Review

Security architecture risk: 🟡 Moderate · up to af3e0

A completed extension can continue to report Progressing as Succeeded after its revision becomes blocked or unavailable. Available still reports the failure, but consumers that rely on Progressing alone may miss it. The change is limited to the experimental API; no new privilege or attacker-controlled path was established.

Retained concerns

• Medium · security · inferred: After a revision has completed, a later Blocked or unavailable state can coexist with ClusterExtension Progressing=True/Succeeded. A consumer using Progressing as its sole rollout-health signal could miss a subsequent failure, including a referenced-Secret verification failure.

Security review details

Security Blast Radius

• inferred — The identified inconsistency affects experimental CE status consumers that use Progressing without checking Available. CE Available still receives the installed revision’s current Available condition, limiting the misleading signal to consumers of only part of the contract.

Security Findings and Attack Paths

• inferred — After first completion, a failed referenced-Secret verification can produce COS Available=False/Blocked while CE Progressing remains Succeeded on the next successful projection. No ability for a weaker identity to cause or forge that transition was established.

Trust Boundaries and Controls

• observed — The operator selects COS revisions by owner-name label and consumes their status; this selection predates the change. The inspected deployment manifests did not establish who can write the COS status subresource, so attacker-controlled status is not assumed.

Resilience and Maintainability Implications

• inferred — Keeping completion and current revision health as distinct signals is workable only if downstream status preserves that distinction consistently; the unconditional Succeeded mapping obscures a later blocked state in one CE condition.

Hardening Proposals

• proposed — Define whether CE Progressing represents historical completion or current rollout health, then make the completed-revision mapping and consumer guidance explicit for subsequent Blocked and unavailable states.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Honor an unavailable condition on completed revisions.

CompletedAt remains set after a later ClusterObjectSet reconciliation reports Available=False. Revision-state retrieval still classifies that revision as installed, so the installed path calls progressingFromAvailable(avail, true). The completed branch returns Progressing=True/Succeeded before it evaluates Available=Blocked or ProgressDeadlineExceeded.
