feat(recipe): per-value readiness constraints for configuration profiles - #2347
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.

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.

The mechanism reads correctly to me and my earlier ADR finding is fully addressed — all three drawn values now own installer.enabled, ownedPaths records [enabled, installer.enabled], and the adoption step matches. Thanks.
Two things before merge, both inline.
The first is a contract conflict: the field comment and the integrator guide both tell integrators to use readinessConstraints for a marker the value's own workload creates, while the ADR rule added in the same PR requires state independent of the bundle's own output. These need to be one coherent rule.
That also leaves the PR without a confirmed consumer. The agreed direction in #2360 withdraws the ambiguous GKE value, and #2363 has not chosen between Option A (grounded OCI pool projection), Option B (two-value profile), and Option E (defer) — two of those three need no readinessConstraints at all. Strict decoding means a catalog using this field is hard-rejected by older aicr binaries, so shipping it unused carries a real compatibility cost. I would rather resolve #2363 first and merge this alongside a consumer.
To be clear about what I am not saying: the self-falsifying pre-condition trap this PR documents is a genuine hole in ADR-015, independent of any family, and both use-rules added to the ADR are worth keeping regardless. If we ship the mechanism ahead of demand on that basis, that is defensible — I would just like it made deliberately and reflected in the body.
Operational: tests / Test is failing on TestRunReportsCurrentAliasMappings in tools/api-diff-closure (120s timeout), unrelated to this diff but blocking gate. The branch is 4 ahead / 42 behind main; the rebase itself simulates cleanly, but this PR and #2360 have a confirmed ADR content conflict in the sketch, the ownedPaths example, and the adoption step, so expect manual resolution if #2360 lands first.
…traints The ReadinessConstraints godoc and integrator guide presented a marker the value's own workload writes as a distinguishing signal, contradicting the ADR rule that qualification requires bundle-independent state. The contract now names both legal kinds — deployment-outcome checks (post-forms of self-falsified pre-conditions, workload-written markers: they verify execution and can fail, unlike a rendered .spec readback) and externally-grounded state — and states that only the latter qualifies a value, in the ADR mechanism section, the godoc, and the integrator guide.

…iagnostics Adds the same-path-in-both-phases routing test (gen pre-condition evaluated and kept in spec.constraints; readiness post-form routed unevaluated), the no-readiness negative (nil Validation stays nil), and a strict-decode YAML round-trip for the readinessConstraints tag. The duplicate-name diagnostic now names which list the repeat is in (the same path is legal in both), and the clone comment no longer overstates the aliasing risk.

State the consumer status accurately.
The Motivation says OKE is the first consumer, calls the provisioning-set label “#2363's chosen direction,” and says it is readiness-scoped by necessity. #2363 remains open with no option selected. Its Option A uses grounded provider state as ordinary durable profile constraints and needs no readinessConstraints; B and E also do not establish a consumer. The label addresses only the advertiser axis, while operator-plugin versus operator-managed still needs an independent driver-ownership signal. The current node-set evaluator is also GKE-specific: its GPU-node universe is hardcoded to cloud.google.com/gke-accelerator (gpu_nodes.go).
Please remove the claim that OKE is a confirmed consumer and state instead that no embedded consumer currently uses the field, #2363 remains unresolved, and this PR deliberately ships the generic mechanism ahead of demand to close the independent self-falsifying-precondition gap. This does not require waiting for #2363.
Qualify what a deployment-created marker proves.
The guide and ADR say a workload-written marker proves the workload or deployment ran. The readiness gate only compares the snapshot value; it has no deployment identity, owner, timestamp, or attempt binding (validator.go). An unversioned marker left by an earlier deployment can therefore satisfy a later outcome check.
Document that an outcome check observes post-deployment state but does not establish which deployment produced it. A workload-written marker is valid only when its producer owns the full lifecycle and clears or versions it when the outcome no longer holds; otherwise soften or remove the marker example. No generic freshness machinery is needed in checkReadiness.
Align the remaining routing comments with the two-kind contract.
The routing comment says all readiness constraints name properties that cannot exist in the pre-deployment snapshot (profile_resolution.go); the new test comment repeats that statement (profile_readiness_test.go). That is no longer true under the updated contract, which also permits externally grounded provider properties and provisioning labels evaluated at readiness. Reword both comments to describe the two legal kinds without asserting universal pre-deployment absence.
Out of scope
None.
An outcome check observes post-deployment state but binds no deployment identity — the readiness gate compares only the snapshot value, so a stale marker from an earlier deployment satisfies a later check; workload-written markers are valid only when their producer owns the marker lifecycle.

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.No embedded consumer uses the field yet, and this PR does not depend on one landing: it deliberately ships the generic mechanism ahead of demand, because the self-falsifying-precondition gap is independent of any one family — a value whose deployment erases its own pre-condition (e.g. a generation-time "no driver loaded" gate on a value whose operator installs the driver) currently has NO legal home for that state: as a generation constraint it fails every post-deployment validate on a healthy cluster. The likeliest first consumer is the OKE gpuStack family (#2363, unresolved — its Option A would use grounded provider state as ordinary durable constraints and need no
readinessConstraintsat all; note also the node-set evaluator's GPU-node universe is currently GKE-specific,gpu_nodes.go). Whatever #2363 selects, deployed ClusterPolicy readings (K8s.policy.*) cannot serve as distinguishers: the collector flattens.spec, the bundle's own rendered output, which every value satisfies by construction (#2363 Option C, rejected).Fixes: N/A

New tests:

pkg/recipe89.4% → 89.5% (+0.1%).Risk Assessment
Rollout notes: Additive schema field; unused by any embedded declaration until the follow-up PR. Strict decoding means older aicr versions reject a catalog that uses the field — the first consumer, when one lands, ships with the binary that understands it.
