checkCoverage compared consecutive from intervals and never compared the merged upper against the pin, so a record whose coverage stops below the pin was accepted while every version in between matched no transition. That is the shape a record has right after a pin bump nobody extended it for. The len(trs) < 2 early return also skipped single-transition records entirely; it drops to len(trs) == 0. The rule 2 and rule 7 tables now assert on their own rule's wording: the three rules constrain the same two ranges from different directions, so a fixture isolating one is often not well-formed under another. Signed-off-by: Alex Yuskauskas <ayuskauskas@nvidia.com>
checkPinCeiling refuses to presume Load ran, but checkVerdictFields' unknown/unversioned arm was an empty no-op justified by the opposite reasoning, the switch had no default, and nothing checked summary. A Set built directly with a garbage verdict, no verifiedBy, no steps and no summary validated clean, which also left Load's own gates deletable with a green suite. Both arms now report a non-authorable verdict and the summary check moves in beside them, replacing checkReplaces' duplicate of it. Signed-off-by: Alex Yuskauskas <ayuskauskas@nvidia.com>
Rule 8 keyed only on the to floor, so two transitions reaching one boundary from disjoint from domains were rejected — but under ADR:182's applies predicate at most one of them can ever match a given source, so the 'would resolve to blocked' justification does not hold for that shape. The two duplicate shapes the spec names both intersect, so requiring an overlap is strictly compatible with the stated intent. reversibleNotes now follows Ruling 10: only reversible: true requires them. ADR-021's own worked example carries reversible: false with none. Signed-off-by: Alex Yuskauskas <ayuskauskas@nvidia.com>
ADR:245 specifies the location and ADR:310 explains why it is load-bearing: tools/bom walks only .../manifests and recipes/manifest_images_test.go skips paths without /manifests/, so a hook anywhere else carries an image nothing pins and the BOM never sees. A hook at values.yaml was accepted. Signed-off-by: Alex Yuskauskas <ayuskauskas@nvidia.com>
IsSupportedAuthoringAPIVersion also admits aicr.run/v1alpha2, which contradicts ADR-021:149 and ADR-022:103/:283 — the kind starts at its target precisely so there is no alpha version to emit and later retire. Load also panicked on a nil Source when a component named a file; it now returns ErrCodeInvalidRequest naming the file. Test fixtures using real registry component names are renamed to synthetic ones. Signed-off-by: Alex Yuskauskas <ayuskauskas@nvidia.com>
Every Validate test used a single-key Set, so deleting sort.Strings left the suite green while multi-component output order became randomized map iteration. The new test runs the walk repeatedly, because one range over a small map can land on ascending order by luck. Nothing anywhere asserted that a realistic multi-transition record satisfies all nine rules at once, and replaces had never been exercised through a YAML decode. Signed-off-by: Alex Yuskauskas <ayuskauskas@nvidia.com>
go test -run exits 0 with [no tests to run] when the pattern matches nothing, so renaming the test disabled the gate silently and forever. The script now anchors the pattern and asserts the PASS line; both -run and the grep were unanchored, so a renamed test still matched by prefix. The gate was also only as wide as the registry: a record whose upgrades.file path, embed pattern, or filename is wrong is never read, and every rule then passes vacuously over the empty component list that leaves. Records under upgrades/ that no entry references now fail. The test's doc comment claimed it walked the committed tree when it walked the registry; now it does both. Signed-off-by: Alex Yuskauskas <ayuskauskas@nvidia.com>
Rule 1 is the loader's apiVersion and kind gate and was named nowhere in the package, so a reader told there are nine rules found eight, numbered 2 to 9. The godoc now maps every rule to the function that enforces it. Signed-off-by: Alex Yuskauskas <ayuskauskas@nvidia.com>
checkHooks tested the manifests/migrations/ prefix against the raw hook file string. filepath.IsLocal only rejects paths that escape the bundle root, so a ".." that stays under the root while still walking back out of the tree (e.g. manifests/migrations/../../values.yaml, which cleans to values.yaml) satisfied both checks and was accepted. Test the cleaned, slash-normalized path instead. Signed-off-by: Alex Yuskauskas <ayuskauskas@nvidia.com>
Rule 2 (checkPinCeiling) only ever compares upper(to) against the pin, so an inverted or otherwise empty to range (e.g. ">=0.30.0 <=0.19.0") validated clean: its upper bound sits below the pin even though the range matches no version at all. checkDirectional already guards the symmetric case for an empty from; add the equivalent guard for to, in checkPinCeiling since it already owns to's structural well-formedness checks. Signed-off-by: Alex Yuskauskas <ayuskauskas@nvidia.com>
grove is pinned at a prerelease (v0.1.0-alpha.12), and a record whose upgrade history crosses more than one prerelease boundary before that pin needs a prerelease floor on from, not only a prerelease ceiling on to. The prereleasePolicy knob that forbade it in from is now dead configuration (no caller can select the forbidden mode), so it is removed along with the parameter on parseBounds/parseRangeVersion.

Reviewed at 5048678. I verified each finding below by running code against the branch rather than by reading, so the three marked confirmed are reproducible rather than suspected.
Three inline comments are confirmed defects; two are smaller notes. Nothing here is structural, and the design holds up well under probing (see the last section).
One note on the PR description rather than the code
a restricted grammar (a single AND-group of simple comparators) is parsed here while Masterminds still decides membership
That is not true in this PR yet. Nothing in production calls Masterminds: newConstraint and bounds.contains are referenced only from bounds_test.go. They are forward-looking helpers for #2528, and TestBoundsAgreeWithMasterminds is a tripwire for a future consumer rather than a guard on current behaviour.
Worth correcting, because a reviewer reading that sentence assesses the dual-representation divergence risk as live when it is not yet. The tripwire is still the right thing to have; it just is not load-bearing today.
What I checked that came back clean
I built the same data model independently against ADR-021 before finding this PR, which made it easy to probe where the two disagree. Several of your calls are better than mine, and it is worth recording why:
checkCoverageis right, and literal adjacency is genuinely weaker. Your argument that the ADR's wording is vacuous for<X-shapedfromranges holds. A concrete shape that adjacency passes and coverage catches:A.from "<1.0.0" / A.to [5.0,5.0]withB.from ">=4.0.0 <6.0.0" / B.to [6.0,6.0]. Thefromunion has a hole at[1.0, 4.0), butB.fromdoes intersectA.to, so adjacency reports nothing. Both transitions satisfy rule 7, so it is reachable, not theoretical. I also confirmed coverage catches interior holes and short-of-pin gaps, does not false-positive on a wholly contained range, and validates ADR-021's own nodewright worked example with zero violations.- Declaring
canonicalDeployerslocally with a drift test instead of importingpkg/bundler/configand its 621 transitive packages. - Rejecting build metadata in ranges. I accepted it, which is wrong for a ceiling rule, and your comment explains exactly why.
tools/check-upgrade-recordsgreps for the--- PASSline becausego test -runexits 0 on "no tests to run". That closes the spuriously-passing-negative-check anti-pattern in CLAUDE.md deliberately.
Tests green locally: pkg/upgrade 97.3%, pkg/recipe 90.2%.

Confirmed: a multi-document record file silently drops everything after the first document.
decodeRecord calls Decode once and never checks for a trailing document. I appended a second, entirely valid ComponentUpgrades document to a good file and it loaded clean with 1 transition and no error; the second document vanished.
That is the silent-failure class this package exists to prevent, arriving inside the loader: an author who appends a record to a file gets it ignored with nothing to tell them. It is the same shape as the apiVersion argument in the package doc, since "a record exists and I could not read it" and "a record exists and I did not look at it" are both not "no record exists".
One block fixes it, after the first Decode succeeds:
switch err := dec.Decode(new(ComponentUpgrades)); {
case errors.Is(err, io.EOF):
// The sole document was the last one, as required.
case err == nil:
return nil, errors.New(errors.ErrCodeInvalidRequest, fmt.Sprintf(
"%s contains more than one YAML document; a %s file holds exactly one", c.File, ComponentUpgradesKind))
default:
return nil, errors.Wrap(errors.ErrCodeInvalidRequest, fmt.Sprintf(
"failed to parse %s past its first document", c.File), err)
}(stdlib errors is aliased stderrors in files importing pkg/errors.)

Fixed in 28e89290.
Took your block as written. One decision beyond it: a bare trailing --- with no second document is also rejected. yaml.v3 decodes that to err == nil with a zero-value struct rather than io.EOF, so it would have needed explicit special-casing to allow — and distinguishing "intentionally empty second document" from "truncated file" is exactly the ambiguity this rule fails closed on everywhere else.
Also added TestLoadRejectsUnparseableSecondDocument to cover the default branch, which was otherwise the one newly-added path with no test.

Confirmed: this ordering leaves a hole in ADR-021 Acceptance Criterion 11.
AC11 requires that a record with an unrecognized apiVersion fail "naming both values". This check runs before the kind gate on L105 and the apiVersion gate on L112, so a record that is both on the wrong apiVersion and empty reports the emptiness instead:
apiVersion: aicr.run/v1alpha2
kind: ComponentUpgrades
component: c1
[INVALID_REQUEST] upgrades/c1.yaml declares neither transitions nor a replaces block; a record that asserts nothing must not read as well-formed
Neither v1alpha2 nor v1beta1 appears, so an author on the wrong schema version is told the wrong thing.
Narrow, but the fix is free: move the kind and apiVersion checks above this one. Header identity should be established before the document's contents are judged anyway, since an empty transitions list is only meaningful once you know it is a ComponentUpgrades at all.
There was a problem hiding this comment.
Fixed in 655f5c00. kind and apiVersion now gate at loader.go:123 and :130, ahead of the emptiness check at :137, so a record that is both wrong-version and empty now names both version strings.
Worth recording that this was a known deferral on my side, not a discovery: I had it in my notes from the task that wrote this function, graded it message-only because the record is rejected either way, and carried it. Connecting it to AC11 is what makes it not message-only, and I missed that. Good catch.

Confirmed: Set{"c": nil}.Validate(...) panics with a nil pointer dereference on u.Transitions.
CodeRabbit raised this as well; I reproduced it independently rather than take it on trust.
It is worth more than the usual "caller did something odd" weight here, because the package already reasons about exactly this path. checkPinCeiling re-parses bounds specifically because "Validate is exported on an exported map type, so a Set can be built without ever going through Load" — so the unvalidated-caller path is acknowledged in one rule and unguarded in the function that dispatches all of them.
A skip with a violation rather than a panic keeps Validate's aggregate contract:
if u == nil {
return []string{fmt.Sprintf("component %q has a nil record", name)}
}There was a problem hiding this comment.
Fixed in 60fa96e7, using your named form — Validate now threads the map key through so the violation reads component "c" has a nil record rather than an anonymous message.
Your framing is the part that decided it: checkPinCeiling re-parses bounds specifically because a Set can be built without Load, so guarding one rule while the dispatcher panics on the same class of input was incoherent. Test asserts a violation and no panic.

A fourth deviation from ADR-021 that the PR description does not flag.
This rejects partial versions, so ADR-021:208's stated ordinary idiom does not parse:
range ">=25.0 <26.0": version "25.0" is not a full X.Y.Z version; a partial version silently expands and reads as approximate
To be clear, I think the strictness is correct. I accepted partials and coerced them in my own attempt, and silent expansion is the worse behaviour for a rule whose whole job is bounding a ceiling.
The ask is bookkeeping, not a code change: the description flags three deviations and two additions, and a reader reconciling the PR against the ADR will hit this one unannounced. Since deviations 1 and 2 already require amending the ADR, ADR:208's "one-character edit" example needs to land in the same amendment, because that example does not parse under this rule.
There was a problem hiding this comment.
Agreed on both halves — the strictness stays, and the bookkeeping was my miss.
Updating the PR description to declare this as a fourth deviation. And you are right that it belongs in the same ADR amendment as deviations 1 and 2 rather than a separate one: ADR:208's example is already being rewritten there, because from: ">=25.0 <26.0" / to: ">=25.0 <=25.3" also fails rule 7 under ADR:182's own applies predicate — it matches a 25.3 to 25.1 downgrade. So that example needs to change for two independent reasons, and the "one-character edit" framing around it changes with it.
Related consequence worth having in the same amendment: with rule 3 enforcing coverage up to the pin, rules 2, 3 and 7 jointly force a single-transition record's to to sit exactly at the pin — so no single-transition per-major-line record is expressible at all, and the minimum is two per line.

Minor: PropagateOrWrap returns the inner error unchanged when it already carries a *StructuredError, which LayeredDataProvider.ReadFile does (it wraps through aicrerrors in pkg/recipe/provider.go). So on the path this message is written for, the component name and file path are both dropped and the author sees only the underlying read error.
PropagateOrWrap is the right tool when you want to preserve an inner code you would otherwise clobber. Here the added value is context, not classification, so errors.Wrap with the same code gives you both:
return nil, errors.Wrap(errors.ErrCodeInternal, fmt.Sprintf(
"failed to read upgrades file for component %q from %q", c.Name, c.File), err)I hit this identical trap in my own version of this loader, which is the only reason I spotted it.

Fixed in da29155a. You are right about the mechanism — I checked pkg/errors before changing anything: PropagateOrWrap returns the inner error unchanged when it is already a *StructuredError, so on the LayeredDataProvider path the component name and file path were both discarded.
Switched to errors.Wrap with the same code. TestLoadPropagatesReadError still passes, because Wrap sets Cause, Unwrap returns it, and StructuredError.Is matches on Code — so stderrors.Is(err, errors.New(ErrCodeNotFound, "")) still finds the inner code through the chain. Extended that test to also assert the message now carries the component name and path.

Second pass, same commit 5048678. I ran a separate review lane over the diff and it surfaced things my first review missed. I verified each before posting; two held up, the rest are smaller or turned out weaker than first stated.
The manifests/migrations/ one is the notable one, and it is a better find than anything in my first round.
Calibrated down after checking
- Overlay pins vs
pinnedVersionFor. The concern was thatpinnedVersionForreads onlyhelm.defaultVersion, so an overlay pinning a chart above the registry default ships a version rule 3 never requires afromdomain to cover. The mechanism is real, but the one divergence in the tree points the other way:recipes/overlays/aks.yaml:190pinskube-prometheus-stackat83.7.0against the registry's84.4.0, so coverage to the registry pin is a superset and nothing is uncovered today. Worth carrying to #2535 where the coverage gate actually lands, rather than treating it as a defect here. orphanUpgradeRecordsand the embed interlock. I said in my first review that the interlock is covered, and for a referenced record it is:LoadcallsReadFilethrough the embedded provider and fails loudly when the pattern is missing. The narrower gap is real though. A record that is on disk, not embedded, and not referenced fires nothing at all, becauseWalkDirover the embedded FS cannot see it. So the helper's doc comment atupgrade_records_test.go:80over-claims slightly when it says the check catches "a record whose ...//go:embedpattern ... is wrong". Only the referenced half is caught, and byLoadrather than by this helper. A sentence fix, not a code fix.- Two trivia in the same helper:
strings.HasSuffix(p, ".yaml")misses a.ymlrecord, andMakefile:111's##help text was not extended whencheck-upgrade-recordsjoined thelintchain.

This rationale does not hold, and rule 9 currently steers hooks into a blind spot rather than out of one.
The comment justifies manifests/migrations/ on the grounds that recipes/manifest_images_test.go skips any path without /manifests/. That test walks the embedded FS (fs.WalkDir(FS, "components", ...)), and the glob in recipes/data.go:21 is:
components/*/manifests/*.yaml
* does not cross / in a //go:embed pattern, so components/<name>/manifests/migrations/x.yaml is never embedded, and the image-pin gate never sees it.
I verified this rather than inferring it. I dropped a real file at recipes/components/nodewright-customizations/manifests/migrations/probe-hook.yaml carrying a Job image nvcr.io/nvidia/probe-migrate:1.0 (tag, not digest), then walked the embedded FS and ran the gate:
embedded files under that manifests dir:
[bcm-setup.yaml no-op.yaml tuning-generic.yaml tuning-gke.yaml tuning-rke2.yaml tuning.yaml]
--- PASS: TestComponentManifestImagesAreFullyQualified
The file is absent from the embedded FS and the gate passes green with an unpinned tag sitting on disk. Only the tools/bom half of the rationale is true, since it walks on-disk recursively.
That inverts the intent: hooks are the one field that lets a safe verdict carry work, and this rule points them at the single subdirectory depth the pin gate cannot reach. Nothing validates that a hook path resolves either, so a typo'd hook also passes make lint silently.
This is the same embed interlock the PR already flags for upgrades.file, one directory deeper and unflagged. Adding components/*/manifests/*/*.yaml to the embed patterns alongside the first hook would close it. At minimum the comment should not claim a property the tree does not have.
There was a problem hiding this comment.
Fixed in f8dd9fc1 — you were right, and I reproduced it before changing anything rather than taking the write-up on trust. tools/bom/main.go does use a recursive filepath.WalkDir and reaches the tree; recipes/manifest_images_test.go walks the embedded recipes.FS, and the pattern is components/*/manifests/*.yaml, so nothing under migrations/ is ever embedded and that gate is blind to it.
The comment no longer claims the property. It now states which gate covers the tree and which does not, and why — and records the interlock: the first PR adding a real hook manifest must also add components/*/manifests/*/*.yaml to recipes/data.go, or those images sit outside the pin gate. I also corrected the runtime error string, which carried the same claim.
The real fix cannot land here for the same reason as the upgrades/*.yaml one: a //go:embed pattern matching zero files fails to compile. That is now two embed interlocks this branch hands forward, both landing on whoever authors first — so I have pulled them into a single place in the PR description rather than leaving them in two code comments.

The new registry field needs its docs in this PR.
CLAUDE.md is explicit that a recipe/registry field addition updates docs/ in the same PR rather than deferring. This PR touches no docs/ file, and upgrades appears nowhere under docs/contributor/.
Two concrete targets, both of which already carry healthCheck.assertFile as the precedent this field is modelled on:
docs/contributor/recipe.md, theComponentConfigfield table (healthCheck.assertFileis the row at :101)docs/contributor/component.md, both the "Optional blocks" bullet list and the field table near the bottom
recipes/registry.yaml's own header comment enumerates the registry fields too, and did not gain upgrades.
Worth a short Transition records subsection under the Registry heading in recipe.md while you are there: the authorable-vs-computed verdict split and the fail-closed rules are exactly the things a first-time record author needs and cannot get from the field table alone.
There was a problem hiding this comment.
Fixed in a758de61. Straightforward miss on my side — CLAUDE.md is explicit and I shipped no docs/ change at all.
Followed the healthCheck.assertFile precedent to each place it appears: the ComponentConfig field table in docs/contributor/recipe.md, both the Optional blocks list and the field table in docs/contributor/component.md, and recipes/registry.yaml's header comment.
Also took the Transition records subsection you suggested, covering the things a field table cannot: the authorable-versus-computed verdict split, safe requiring verifiedBy, the loader failing closed rather than degrading to unknown, and the remainder-group rule where an omitted deployers and an explicit deployers: [] mean opposite things. Linked ADR-021 for the full field reference instead of duplicating it.
decodeRecord decoded only the first YAML document in an upgrades file and never checked for a trailing one, so an appended second ComponentUpgrades document loaded clean and silently vanished — no different from the apiVersion mismatch this package already fails closed on. After the first document decodes successfully, a second Decode call now distinguishes io.EOF (the sole document, as required) from a well-formed second document (rejected by name) from an unparseable one (rejected with the parse error). A bare trailing --- decodes to a well-formed empty document rather than io.EOF, so it is rejected the same as any other second document rather than special-cased as harmless.

Set is an exported map type, so a caller can build one without going
through Load — e.g. Set{"c": nil} — and validateRecord dereferenced
the record unconditionally, turning that into a panic instead of a
reported violation. Validate is exported specifically to let a Set be
built without Load, so a nil entry has to be a violation like anything
else Load itself would already reject, not a crash. validateRecord now
takes the map key so it can name the offending component.

decodeRecord ran the "declares neither transitions nor a replaces block" check before the kind and apiVersion gates, so a record that was both on the wrong apiVersion and empty reported only the emptiness — neither the actual nor the expected apiVersion appeared in the error. ADR-021 AC11 requires an unrecognized apiVersion to fail naming both values. Header identity has to be established before the document's contents are judged: an empty transitions list is only meaningful once the document is known to be a ComponentUpgrades at all, so the kind and apiVersion checks now run first.

LayeredDataProvider.ReadFile already returns a *StructuredError, so PropagateOrWrap returned it unchanged on the exact path this call site was written for, dropping the component name and file path that Sprintf built for it. PropagateOrWrap is for preserving an inner code that would otherwise be clobbered; here the added value was context, not classification, so this now uses Wrap, which sets Cause and keeps the inner code reachable through errors.Is via Unwrap. Signed-off-by: Alex Yuskauskas <ayuskauskas@nvidia.com>
TestComponentUpgradesDecode asserted len(...) != 0, which also passes when Deployers decodes to a non-nil empty slice — the exact shape checkStepGroups treats as a bug rather than the remainder group (an explicit deployers: [] is rejected, only an absent key means remainder). A decoder regression converting an omitted key to [] would have passed this test unnoticed. Asserting != nil pins the distinction the production code actually depends on.

recipes/manifest_images_test.go walks the embedded recipes.FS, and recipes/data.go's //go:embed pattern components/*/manifests/*.yaml does not cross the / before migrations/, so a hook manifest under manifests/migrations/ is never embedded and that test never sees it. Only tools/bom, which walks the on-disk tree with filepath.WalkDir, actually covers hookDir today. Correct both the hookDir doc comment and the runtime validation message to state this accurately, and record the embed-pattern interlock the first real hook manifest must close - mirroring the one pkg/recipe/upgrade_records_test.go already documents for recipes/upgrades/*.yaml.

CLAUDE.md requires a registry field addition to update docs/ in the same PR. upgrades.file had no documentation anywhere, modeled here on its existing healthCheck.assertFile precedent: a row in the ComponentConfig field table and an entry in the registry header comment's field enumeration, plus the "Optional blocks" bullet list and field table in component.md. Adds a short Transition records subsection under docs/contributor/recipe.md's Registry heading covering the record location, semver-range keying, the three authorable verdicts, the fail-closed loader, and deployer step grouping, linking ADR-021 for the full field reference.

CI is green on Noting the cause of the earlier red, since it looked like a failure in this PR and was not one. One test built its "alpha" fixture as Fixed in Verified against the merge commit rather than the branch head, since that is what CI builds: The branch is 8 commits behind. I have not rebased — that is a force-push, and it would outdate the inline comment anchors on this PR while review is still open. Happy to do it whenever it is wanted for the merge gate. |
Question on record placement, not a blockerThanks for turning the earlier round around so fast. Everything I raised is fixed, and I verified each one by running it rather than reading the commits. One design question before this merges, while it is still free to change. Why I know ADR-021 Decision 2 specifies the former and says it mirrors
All 45 Three things make co-location look better here specifically: 1. It removes the embed interlock entirely. _, err := FS.ReadFile("components/nodewright-operator/upgrades.yaml")
// RESULT: already embedded by the existing components/*/*.yaml patternThat erases the zero-match 2. The record would sit beside the manifests it references. ADR-021 puts hook files under 3. Deleting a component becomes one directory instead of three. The cost is a fifth ADR-021 amendment on top of the four already pending, which is not nothing. Against that: zero records are authored today, so moving it is a path string and a test fixture now, versus a migration later. Genuinely your call and the maintainers', and you may have a reason that does not show up in the diff. If the answer is "the ADR says so and the amendment budget is already spent," that is a fine answer and I will drop it. Flagging it now only because the window where this is free closes when the first record lands. |
PR #2704 landed ADR-021 Decision 2's data model: the record schema, a fail-closed loader, and the well-formedness rules (no matcher, no CLI yet). Implementation disproved six points in the decision text: - Rule 3 is interior-hole coverage over the from domains, not the adjacency check this decision described, which was vacuous for the <X-shaped from ranges the ADR's own example uses. AC10 restated the same wrong wording and needed the same fix. - The stated ordinary idiom (one record per major line) fails directionality once a matcher exists, and forces a two-transition minimum (a boundary transition plus a rolling head) per line. The cost argument built on it is rewritten accordingly. - Range bounds require a full X.Y.Z; the "one-character edit" example used partial versions that the implementation rejects. - A non-comparable pin (a Kustomize defaultTag on a branch or commit) is now also rejected at authoring time, not only assigned the unversioned verdict at check time. Currently theoretical: the registry has zero Kustomize components. - The well-formedness check enforces nine rules, not seven: rule 8 (distinct boundaries) and rule 9 (hook validation) were added by adversarial review. - Records live at recipes/components/<component>/upgrades.yaml, not the top-level recipes/upgrades/<component>.yaml this decision specified, because the per-component location is already covered by recipes/data.go's existing embed pattern. Every path reference is updated to match, including the Testing Strategy table and AC7. Status remains Proposed; the Status block records the revision and implementation state per the ADR-022 convention. Signed-off-by: Alex Yuskauskas <ayuskauskas@nvidia.com>

Summary
Adds
pkg/upgrade— the schema, fail-closed loader, and well-formedness rules for ADR-021 component upgrade transition records — plus theupgrades.fileregistry field and amake lintgate. This is the data model every later issue in the epic reads.Motivation / Context
ADR-021 makes "is this component version transition safe?" a machine-readable question. Records live at
recipes/components/<component>/upgrades.yaml, referenced fromregistry.yaml, and carry semver-range-keyed transitions with a verdict, operator steps grouped by deployer, and the evidence backing asafeclaim.Fixes: #2527
Related: #2424 (epic), #2528, #2529, #2532, #2535, #2536 (all consume this data model)

Component(s) Affected
pkg/recipe)pkg/errors,pkg/k8s) — new siblingpkg/upgradeMakefile,tools/check-upgrade-recordsImplementation Notes
Scope. Schema, loader and rules only. No matcher, no CLI, no cluster reads — those are #2528 and later. Nothing calls
Loadin production yet, and themake lintgate is inert until the first record is authored.LoadvsValidate.Loadanswers "can I read this?" — strict decode (KnownFields(true)), theapiVersion/kindgate, verdict-independent required fields. It fails closed: an unreadable record returns an error naming what was found and expected, and is never skipped or degraded to theunknownverdict, because "a record exists and I could not read it" is not "no record exists".Validateanswers "is this well-formed?" and aggregates every violation rather than the first.Range bounds are parsed in-package, deliberately. Four rules need a semver constraint's lower/upper bounds, and no Go library exposes them — Masterminds, hashicorp, aquasecurity and blang all model a constraint as an opaque predicate. So a restricted grammar (a single AND-group of simple comparators) is parsed here while Masterminds still decides membership, with
TestBoundsAgreeWithMastermindsguarding the two representations against divergence.Four deliberate deviations from ADR-021, and two additions — all flagged rather than absorbed:
<X-shaped examples (lower("<0.18.0")is −∞, so the comparison always holds) and passes on a real gap. This implements the property the ADR's next sentence states — "a hole between them". The ADR asserts adjacency in two places (Decision 2's prose and Acceptance Criterion 10); both need amending.from: ">=25.0 <26.0"/to: ">=25.0 <=25.3"genuinely matches a 25.3→25.1 downgrade under the ADR's ownappliespredicate. Consequently no single-transition per-major-line record is expressible; the minimum is two transitions per line. ADR:208's cost argument does not survive this.unversionedverdict at check time and does not make them an authoring error. Currently theoretical — the registry has zero Kustomize components.from: ">=25.0 <26.0") does not parse. The strictness is deliberate — silent expansion is the worse behaviour for a rule whose job is bounding a ceiling — but it means ADR:208's example needs rewriting in the same amendment as deviations 1 and 2. That example already has to change for an independent reason (it fails rule 7), so the "one-character edit" framing around it changes with it.tolower bound. Overlappingfromdomains stay legal — a jump crossing two blocks must resolve toblocked— but two records describing the same boundary silently convert it frommanualtoblocked.hooks[].phasemust be pre-/post-upgrade andfilemust be local and undermanifests/migrations/. Hooks are the one field that can justify asafeverdict, and nothing validated them.Prereleases are permitted in both
fromandto.groveis pinned atv0.1.0-alpha.12; without this, rules 2, 3 and 7 are jointly unsatisfiable for it and the one registry component documenting a manual CRD migration could not be given a record. Safe becauseIncludePrereleaseis set globally in the single constraint-construction helper.Records are co-located per component, not under a top-level
recipes/upgrades/tree — so there is no record-side//go:embedinterlock.recipes/data.go's existingcomponents/*/*.yamlembed pattern already matchescomponents/<component>/upgrades.yaml, so the first record's author adds nothing to it.One

Rule 9's comment records this; thanks to @lockwobr for disproving the original rationale by experiment.Testing
All green.
make qualifywas deliberately not run locally — CI is the first full-gate run (its e2e lanes provision against a cluster, and the local default context is a production cluster).Coverage:
pkg/upgrade97.3% (new package; floor is 83%). No function at 0%.Testing discipline, per ADR-021: no test asserts a verdict for a real component. Verdicts are validated empirically by #2533/#2534; pinning one here would turn "keep the suite green" into pressure to weaken records. The registry gate asserts well-formedness only, so it cannot be satisfied by writing
safe.The gate was proven falsifiable rather than assumed: a temporary malformed record was added,
make check-upgrade-recordsconfirmed failing onverifiedBy, then reverted. Several rules were additionally mutation-tested — reverting the implementation must fail the covering test — after an earlier round found tests that passed while the behaviour they claimed to protect was unpinned.Risk Assessment
Rollout notes: Additive only. The new
upgrades:registry key is optional and absent everywhere, so every existing entry decodes unchanged.pkg/upgradehas no production caller and no client-go dependency. Themake lintgate iterates zero components until a record is authored. Reverting is a branch revert with no migration.Checklist
