feat(recipe): per-value readiness constraints for configuration profiles#2347atif1996 wants to merge 4 commits into
Conversation
A profile value's distinguishing signal can be a post-deployment property (ADR-015 Deferred Decision 5): something the value's own deployment creates, such as a node label its installer DaemonSet applies. Such a signal cannot be declared today — profile-value constraints are evaluated at snapshot-based generation, where the property cannot yet exist, and the overlay-level readiness block cannot vary per value. Add ProfileValue.readinessConstraints: - validated at catalog load like constraints (non-empty name/value, per-list dedupe) and covered by the measurement-path gate, reported as spec.profile.values.<value>.readinessConstraints[i] - never evaluated at generation: applyEffectiveProfile routes the selected value's list into spec.validation.readiness.constraints, where the aicr validate readiness pre-flight evaluates it fail closed - names deduplicate per phase: the same measurement path may carry a generation-time pre-condition and a readiness-time post-deployment state (the DD5 shape reads NodeTopology.gpu-nodes.label in both phases) - ValidationConfig is cloned before mutation so a cached overlay's pointer is never aliased No embedded declaration uses the field yet, so resolved recipes, digests, and committed evidence are byte-identical. ADR-015 is amended with the DD5 resolution direction and a correction to the operator-selfdriver sketch: the component gate must be a nested key (installer.enabled), not top-level install, which is a component-presence gate and would deadlock resolution.

Address review: the sketch now declares the readinessConstraints it claims (positive marker on operator-selfdriver, symmetric absence on operator), the deferred gke-gpu-driver-version hardening is stated as deferred rather than landing (one constraint per measurement path per phase; needs a label conjunction grammar), a stale shared-namespace test comment now describes per-phase namespaces, and fail-closed is hyphenated as a compound modifier.

One issue in the amended ADR example — details inline. Nothing structural; the mechanism itself reads right to me.

Flagging a direction question that bears on this PR's motivation — raised in more detail on #2348. If we drop the That doesn't invalidate My line comment above stands either way: the ADR example's union-totality issue is independent of this. |

Updating this now that the stack has been reworked. With GKE decoupled, #2355 is Not arguing the mechanism is wrong — a validate-time-only constraint is a reasonable thing to have. But this PR's body and ADR amendment still carry the GKE/DD5 rationale, which no longer applies, and the replacement rationale is the one under discussion on #2355. Worth settling that before this lands, since it merges first. The union-totality comment above is independent and stands either way. |
Address review: the amended example broke the union-totality rule this PR introduces — operator-selfdriver owned the nested installer.enabled while operator and csp-managed still drew the top-level install. All three drawn values now own installer.enabled, and the ownedPaths example records the nested path. The mechanism amendment no longer carries the GKE marker rationale (settled separately by value replacement) and instead records the two rules that govern readinessConstraints use: the self-falsifying pre-condition trap (a pre-condition the value's success erases must not be a generation constraint, since those are re-evaluated at validate), and that self-rendered readings (deployed ClusterPolicy fields) are drift checks, not qualification — a value's distinguishing constraint must read cluster state independent of the bundle's own output.

📋 Multi-persona review — 4 persona passes (Correctness, Domain/Architecture, Test-coverage, Docs), each finding independently confirmed or refuted by a senior meta-reviewer against the resolved code. Line links pinned to head 9d8f6b47.
Tier legend: 🔴 Blocker · 🟠 Major · 🟡 Minor · 🔵 Nitpick · ✅ Confirmed non-issue
Prior reviewers: @yuanchen8911's union-totality finding on the ADR sketch was real and is now fixed at head (9ed09df / 9d8f6b4) — re-verified. CodeRabbit's items are addressed or reasonably declined.
Overall assessment — Approve with comments
This is a high-quality, tightly-scoped additive change. The mechanism is correctly built: applyEffectiveProfile routes readinessConstraints into spec.validation.readiness.constraints with a separate per-phase collision map, never invokes the generation evaluator on them (test-proven), and checkReadiness evaluates them fail-closed. Catalog-load path validation and the #2126 diagnostic both cover the new list; the clone-before-mutate deep-copies correctly; and no recipe data changes, so goldens/digests/evidence are genuinely byte-identical. Nothing blocks merge or CI. The one substantive finding is a PR-body prose contradiction — the OKE motivation cites the exact distinguisher pattern the PR's own ADR rule disqualifies — but it doesn't touch the merged artifact and the ADR text itself is self-consistent.
✅ Confirmed non-issues (checked and cleared)
- Aliasing guard is sound —
cloneValidationPhasedoesmake+copyon Constraints, andConstraintis a pure value struct → full deep copy; the append can't mutate a cached overlay. - Union totality / lock surface —
readinessConstraintscorrectly do not contribute toownedPaths; consistent with per-valueconstraints. No path is locked by a readiness constraint. - Determinism — readiness append order is deterministic (overlay-merge order + declaration slice order); no digest or
sort.StringsAreSortedconsumer requires them sorted. - Strict-decode contract — the struct field is the allowlist (
KnownFields(true));docs/contributor/recipe.mdupdated to listreadinessConstraints. - Routing target actually consumed —
validation.readiness.constraintsis evaluated fail-closed bycheckReadiness(validator.go:56,296,407). - Catalog-load path validation — covers
spec.profile.values.<v>.readinessConstraints(constraint_paths.go:100). - ADR sketch at head is union-total & consistent — all three drawn values own
installer.enabled+devicePlugin.enabled; no stale top-levelinstall:YAML key;ownedPathsrecords[enabled, installer.enabled]. - Docs "fail-closed" hyphenation (flagged by a persona/CodeRabbit) — refuted: hyphenated is the plurality form in
docs/**(46 vs 31), not an outlier. - Tests pass —
go test ./pkg/recipe/... -run 'Readiness|ProfileReadiness'→ PASS.

Recommendation: Approve with comments. Nothing blocks merge. Worth acting on before the OKE follow-up: the PR-body↔ADR contradiction (a prose fix — repoint OKE's stated distinguisher at bundle-independent state). The DD5 same-name-both-phases test is cheap, valuable hardening; the 🔵s are optional.

🟡 Minor — PR-body OKE motivation contradicts the self-rendered-readings rule this PR adds
The PR-body Motivation names OKE's durable distinguishers as "the deployed ClusterPolicy readings (K8s.policy.driver.enabled, K8s.policy.devicePlugin.enabled)", but the ADR rule this same PR adds (this line) disqualifies exactly that: a reading the selected bundle itself renders ("e.g. deployed ClusterPolicy fields") is satisfied by construction under every value and cannot distinguish. Verified: K8s.policy.driver.enabled reads ClusterPolicy .spec (pkg/collector/k8s/policy.go:132), not .status — so it's purely self-rendered and can't fail-closed on a wrong-value selection (each value's own bundle renders the .spec it then reads back).
Blast radius: None on this PR (additive, unused, byte-identical goldens; the mechanism's valid leg — the self-falsifying-precondition trap, "no driver loaded" erased by success — justifies it independently, and the ADR text is internally consistent). It's a coherence gap in the justification and a trap for the follow-up OKE PR, which will hit this rule at catalog load.
Fix: In the PR body, repoint OKE's stated distinguisher at bundle-independent cluster state (a provisioning-set node label or provider property) — which the ADR carve-out and DD5.5 already prescribe. No ADR/code change needed.

🟡 Minor — No end-to-end test for the DD5 same-name-in-both-phases invariant
This routing block plus the two independent collision maps (constraintNames vs readinessNames) exist so one value can carry the same measurement path in both its own constraints (generation) and readinessConstraints (readiness). No test drives that literal shape — the closest case reuses a composed-recipe constraint name, not the value's own generation constraint.
Blast radius: Low today (the maps are provably independent), but this is the marquee invariant the PR exists to enable; a future refactor merging the two maps would pass every current test and silently break it.
Fix: Add a readinessDecl variant where readiness carries the same name as the value's own generation constraint; assert gen-X lands in spec.Constraints (and is evaluated), readiness-X lands in Validation.Readiness (and is not), with no false collision.

🔵 Nitpick — Clone-before-append is defensively redundant; comment overstates the aliasing risk
Both callers already hand in a mergedSpec whose Validation is deep-cloned (initBaseMergedSpec, RecipeMetadataSpec.Merge), and cloneValidationPhase does a real make+copy of the Constraints slice — so mergedSpec.Validation.Readiness can't alias cached metadata here. The comment's analogy is imperfect: Overrides genuinely alias (a shallow struct copy shares the map), whereas Validation is genuinely deep-cloned.
Blast radius: None — harmless defensive hardening; safe to keep. Only the comment is slightly overstated.
Fix: Optional: soften the comment to "defensive clone; callers already deep-clone Validation."

🔵 Nitpick — Empty-ReadinessConstraints guard has no negative assertion
The len(value.ReadinessConstraints) > 0 guard is self-evidently correct, but no test asserts that an empty list leaves mergedSpec.Validation untouched (no spurious clone, no empty Readiness phase synthesized).
Blast radius: Low; a regression could synthesize an empty Readiness phase onto recipes that declared none, perturbing downstream validation/serialization.
Fix: Call applyEffectiveProfile with a value that has no readiness constraints and spec.Validation == nil; assert spec.Validation stays nil. Cheap if you add the same-name-both-phases test anyway.

🔵 Nitpick — No YAML round-trip test for the readinessConstraints struct tag
No test deserializes readinessConstraints from YAML, so a struct-tag typo isn't caught at this seam.
Blast radius: Largely mitigated already: profiled artifacts decode under KnownFields(true), so a typo'd tag would make a real readinessConstraints: key an unknown field → hard reject at load (fail-loud), not a silent drop.
Fix: Optional round-trip assertion on a ProfileValue with readinessConstraints:. Low priority.

Summary
Adds
readinessConstraintsto profile values (ADR-015): per-value constraints that are validated at catalog load likeconstraints, but never evaluated at generation time — they route intospec.validation.readiness.constraintsand are evaluated fail closed by theaicr validatereadiness pre-flight.Motivation / Context
Some profile values are distinguishable only by deployment-created state, which cannot be declared today: profile-value constraints are evaluated at snapshot-based generation (
applyEffectiveProfile), where such a signal cannot yet exist, and the overlay-levelspec.validation.readiness.constraintscannot vary per value.The first consumer is the OKE gpuStack family (follow-up PR): its three values are three distinct production pool shapes (Oracle image + OKE plugin / Oracle image + operator plugin / operator-managed everything), so no ambiguous sibling can be withdrawn — and
operator-pluginvsoperator-managedhas a destroyed-by-success structure (a generation-time "no driver loaded" gate would fail every post-deployment validate on a healthy cluster). The durable distinguishers are the deployed ClusterPolicy readings (K8s.policy.driver.enabled,K8s.policy.devicePlugin.enabled) — readiness-scoped by necessity.Fixes: N/A
