docs(sdk): add compiled examples and close the integrator contract#2253mchmarny wants to merge 5 commits into
Conversation
docs/integrator/go-library.md documented the facade well but nothing in the tree compiled any of it, so every snippet could rot silently. Four SDK PRs in a row shipped documentation defects caught only in review. Add Example_* functions covering the epic's surface: quick start, error codes, committed AICRConfig, snapshot relaxation, bundle+verify, evidence verification, binary attestation, and the two enumerations. go test compiles all of them and runs the four with stable output, so a facade change that breaks a documented flow fails here first. They earned it on the first run. Example_trustLevels asserted the levels came back highest-first; TrustLevels() is documented as alphabetical and returns alphabetical. The example comment was wrong, not the function. Also close drift the acceptance criteria name: - public-api.md listed 5 transparent aliases; the package godoc says 7. Add BundleVerifyReport and EvidenceVerification, plus rows for Config and the CriteriaDimension constants. - The package godoc's surface list predated LoadConfig/Config (#2026) and WithSnapshotCriteriaRelaxation (#2027). - The Errors section taught errors.As plus a manual code comparison. StructuredError.Is matches on code, so errors.Is is the documented preference; errors.As is now shown only for reading Context payloads. Add an integrator contract section stating what is guaranteed, what the api-diff gate does and does not cover (signatures, not behavior), and how to report a missing capability instead of routing around the facade.

Two blocking review findings.
The canonical bundle example could not succeed. It discarded the
BundleArtifact (so HasErrors was unchecked), ignored Report.Errors, and
demanded MinTrustLevel "verified" from a bundle built with the default
no-op attester — which reaches "unverified" at best. Confirmed:
MinTrustLevel="" -> trust=unverified policyFailure=""
MinTrustLevel="verified" -> policyFailure="trust level \"unverified\"
does not meet minimum \"verified\""
Being compile-only hid it: nothing ran, so nothing failed. The flow is
actually hermetic, so the example now RUNS — temp dir, no network, no
signing — checks all three failure channels, and asserts trust level
"unverified", with the reason it cannot be higher stated in the godoc.
"Every flow on this page has a compiled counterpart" was false: it
omitted CollectSnapshot, ValidateState, LoadRecipe, VerifyCatalog,
RecipeDigest, PublishEvidence, and SignCatalog. Rather than only narrow
the claim, add all seven, and narrow it anyway — the table now lists
16 examples with a per-example Runs column, and says plainly that
compilation pins signatures rather than proving runtime behavior, and
that the guarantee covers the examples and not the page's prose.
Also: the relaxation example's comment said "passing none — as here"
while the call passes DimensionIntent, and the godoc credited WrapConfig
with parsing that only LoadConfig does.

Review found two; auditing the same class found two more. Reported: - "Each Client entry point" — ExampleVerifyBinaryAttestation is package-level, not a Client method. Now "facade entry point". - ExampleClient_ValidateState claimed three-phase validation while selecting only deployment and conformance. State that validation comprises three phases and that this example narrows to two via WithValidationPhases; the guide's table row matches. Found while sweeping for the same defect: - ExampleClient_LoadRecipe advertised "Path, URL, or cm://". LoadRecipe reads a file or a cm:// ConfigMap; it does NOT accept an HTTP(S) URL. That contract belongs to LoadSnapshot and I copied it across. The guide had it right, so the error was confined to the new example. - Both catalog examples used "catalog.sigstore.json"; the released asset is recipe-catalog.sigstore.json. VerifyCatalog's example also now records that the digest binds to THIS Client's DataProvider, so a layered external source not matching the release signature is the correct answer rather than a failure to work around. The WrapConfig parsing claim was already corrected in 9d5ecde. Signed-off-by: Mark Chmarny <mark@chmarny.com>

Three new canonical examples compile but cannot perform what their surrounding prose claims. Since the PR's contract is that these are copyable, each one leaves an SDK caller unable to reproduce the documented behavior, because in all three cases the CLI supplies something the facade does not.
Details in the inline comments. Nothing else in the diff blocks; the rest of the examples check out against the facade's actual behavior.

This example cannot exercise the relaxation it demonstrates, and the comment above it describes a flow the facade does not offer.
ResolveRecipeFromSnapshotWithOptions uses snap only to build the constraint evaluator (aicr.go:850-870); it never derives criteria from the snapshot. So "the rest came from the snapshot" is not what happens here — criteria holds only Intent, and every other dimension stays unset.
That makes the relaxation inert. The resolve call itself may well succeed; what cannot happen is the retry. relaxDerivedCoverage (relax.go:239+) clears only dimensions the coverage post-condition reports uncovered, and an unset dimension is never requested, so it is never uncovered. With Intent also declared stated, relaxDerivedCoverage can only return ok=false, RelaxedDimensions is guaranteed empty, and the loop below is dead code.
There is also no criteria-derivation entry point on the facade at all — only the three ResolveRecipeFromSnapshot* methods — so a caller cannot reconstruct the CLI flow this claims to reproduce. Either state a second dimension explicitly and mark only Intent as stated, so relaxation is reachable, or narrow the prose to say the caller supplies all criteria and relaxation applies to whatever it did not name.

Confirmed and fixed in 09850c63. You and @njhensley are both right, and this was the worst defect in the PR — the flagship example taught a wrong mental model.
Verified the mechanism rather than taking it on faith: grep -n "fingerprint\." pkg/client/v1/*.go returns nothing. The facade never derives criteria from a snapshot. And uncoveredDimensions skips anything failing isSpecifiedCriteriaValue, so an unset dimension is never reported uncovered — with Intent the only specified dimension and also declared stated, relaxDerivedCoverage could only return ok=false. The loop was unreachable exactly as you described.
I took your first option: the example now supplies Service and Accelerator as derived alongside a stated Intent, and passes only DimensionIntent. Relaxation is reachable.
The prose changed more than the code. It now leads with a section stating that the facade does not derive criteria from the snapshot, that it uses the snapshot only for constraint evaluation and post-processing, that producing criteria from measurements is the CLI's job with no facade entry point yet, and that relaxation is unreachable if you name every dimension you supplied. Your point about there being no criteria-derivation entry point at all is now stated in the example rather than left for a reader to discover.

Correction to my previous reply on this thread — I closed it too early, and re-checking found the fix incomplete. Now actually fixed in ccc9c3b7.
My fix used eks/h100/training as the derived-plus-stated criteria. Those resolve cleanly against the embedded catalog, so coverage never fails, RelaxedDimensions stays empty, and the loop was still dead code. I had made relaxation reachable in principle and left it unreachable in fact — which is most of your original complaint still standing.
Verified rather than reasoned about this time: resolving {eks, h100, training} succeeds on the first attempt, so the retry path is never entered.
Now uses {Service: kind, OS: ubuntu, Intent: inference} with only DimensionIntent stated. No kind overlay states an os, so the derived os comes back uncovered and is relaxed. Confirmed end to end against the real catalog: relaxed=[os], and the loop fires as its comment claims.
The godoc also now names both silent ways to make the policy inert — naming every dimension you supplied, or leaving dimensions unset — since I managed to hit the second one while fixing the first.

Run against a reachable cluster, this example fails: Image, JobName, and ServiceAccountName are all empty.
DeployAndCollect validates only Namespace and ClusterConfigPath (snapshotter/agent.go:441-478). The other three pass straight through into agent.Config (agent.go:174-177) and land in the Job and RBAC objects unmodified (k8s/agent/job.go:81,111,119; rbac.go:87-148). Nothing in pkg/k8s/agent defaults them — the defaults live in pkg/cli/snapshot.go:135-138, which the facade does not share.
On ordering: Deploy creates the ServiceAccount before the Job (k8s/agent/deployer.go:57), so the empty ServiceAccount name is what the API server rejects first, and the caller never reaches Job creation. The empty image and Job name are genuine defects behind it either way.
The comment at agent.go:464-465 already calls the Namespace check "the SDK-caller path," which makes the omission of the other three more conspicuous rather than less. Please set all three in the example.
There was a problem hiding this comment.
Confirmed and fixed in 09850c63. Verified independently: DeployAndCollect validates only Namespace (and ClusterConfigPath), and grep for any defaulting of JobName/Image/ServiceAccountName under pkg/k8s/agent and pkg/snapshotter returns nothing — JobName flows straight into metadata.name at job.go:81.
All three are now set in the example, with a godoc section stating they are required on the SDK path and why: only Namespace is validated, the rest are copied verbatim, and the CLI works only because pkg/cli/snapshot.go supplies flag defaults the facade does not share.
Your note that the Namespace check already calls itself "the SDK-caller path" is what convinced me this is more than an example bug — a comment in the validation code names the gap it does not close. Checking the integration guide found the same omission there (its agent block sets Namespace, Image, and ServiceAccountName but not JobName), so that is fixed too.
Filed #2256 for the underlying ergonomics: the facade should either default these to mirror the CLI or reject them with a coded error naming the field, rather than letting an empty string reach the API server. Out of scope for a docs PR, but it is the actual fix.

With a zero-value OIDCResolve, SelectOIDCSource falls through to the interactive browser flow (attestation/resolver.go:137-147) and reads nothing from the environment. The resulting certificate cannot pass the documented counterpart: browser OIDC is issued by https://oauth2.sigstore.dev/auth, so it fails the verifier's GitHub Actions issuer pin before identity-pattern matching is even reached. SignCatalog succeeds and emits a bundle VerifyCatalog rejects.
Ambient GitHub Actions credentials are necessary but not sufficient. VerifyCatalog defaults to verifier.TrustedRepositoryPattern, which is ^https://github\.com/NVIDIA/aicr/\.github/workflows/on-tag\.yaml@refs/tags/.* (verifier.go:129) — pinned to this repo's tag-release workflow, not to any GitHub Actions job.
This also makes the godoc above the example overstated. rejectUnverifiableCatalogSigning (sign.go:245-269) guards SigningKey, FulcioURL, RekorURL, and DisableTLogUpload, but not the identity source — which is the one asymmetry an SDK caller is most likely to hit.
OIDCResolveOptions aliases bundleattest.ResolveOptions, so AmbientURL and AmbientToken are available here. Either show the ambient-credential form, or say plainly that this is a release-tag-CI-only flow and that a locally signed catalog will not verify.
There was a problem hiding this comment.
Confirmed and fixed in 09850c63. This one lands close to home: an interactive browser flow from a test in this same package is exactly what went wrong during #2218, and I reintroduced the shape in an example.
Verified your chain: SelectOIDCSource falls through to OIDCSourceBrowser when neither an identity token, an ambient URL+token pair, nor device flow is set, and TrustedRepositoryPattern is ^https://github\.com/NVIDIA/aicr/\.github/workflows/on-tag\.yaml@refs/tags/.* — pinned to the tag-release workflow, not to GitHub Actions generally, so your "necessary but not sufficient" point is the important half.
The example now sets AmbientURL/AmbientToken from the Actions OIDC environment, and the godoc leads with "this is a release-CI flow, not a local one", spells out the zero-value trap, and states that a catalog signed anywhere else verifies against nothing.
You are also right that my godoc overstated the guard. rejectUnverifiableCatalogSigning covers SigningKey, FulcioURL, RekorURL, and DisableTLogUpload — I wrote it — but it does not police the identity source, which is precisely the asymmetry an SDK caller hits first. The example now says so explicitly rather than implying the guard is complete.

📋 Multi-persona review — PR #2253 docs(sdk): add compiled examples and close the integrator contract
Method: 3 persona passes (Facade-correctness, Docs-accuracy, Test-coverage/CI-DX), each finding independently confirmed or refuted by a senior meta-reviewer against the resolved code. Line links pinned to head b7314e3.
Legend: 🔴 Blocker · 🟠 Major · 🟡 Minor · 🔵 Nitpick · ✅ Confirmed non-issue
Overall assessment — Comment / Approve with comments
The core goal is met and verified: go test ./pkg/client/v1 compiles all 16 examples and the 5 runnable ones assert only version-stable strings, go vet binds every association name, and the doc-accuracy claims (7-alias table, CriteriaDimension==CoverageDimensionNames test, the errors.Is rewrite, api-diff scope) all check out. No behavior change — the only non-test edit is godoc. Nothing blocks CI or ships a bad artifact. But three compile-only canonical examples carry comments describing runtime behavior the facade does not produce — exactly the drift class this PR exists to kill. They pass CI (never executed) yet mislead any integrator who copies them, so they should be corrected before merge.
✅ Confirmed non-issues (examined, cleared)
- SignCatalog godoc is not overstated (example_test.go:468). @yuanchen8911 and a persona read it as claiming a broad guard; the meta-reviewer disagrees — the em-dash list (
private Fulcio or Rekor, a signing key, or a disabled transparency-log upload) enumerates exactly the four settingsrejectUnverifiableCatalogSigningguards and makes no claim about the OIDC identity source. Narrowly accurate as written. (The underlying reality — a locally-run keyless sign yields a non-CI identity VerifyCatalog rejects — is true but is not something the godoc claims to prevent; an optional one-line note could still help.) - Docs accuracy: alias table (7 exact-target aliases),
Config-is-a-wrapper-not-alias,CriteriaDimensionvalues ==pkg/recipe.CoverageDimensionNames(asserted by TestCriteriaDimensionNamesMatchRecipe), Errorserrors.Isrewrite (StructuredError.Is + Context["uncovered"]), and the api-diff "every PR / signatures-not-behavior" claim — all confirmed against code. - CI/DX: meets #2029's non-negotiable (package
aicr_test, all 16 compile, vet clean); zero production statements added → no coverage impact; 5 runnable examples pass and assert only stable enums; nolog.Fatal; slog output stays on stderr and does not corrupt theOutput:assertions. - Examples with no prose/behavior mismatch: Example, Example_errorCodes, Example_bundleAndVerify, Example_trustLevels, Example_criteriaDimensions, Example_committedConfig, ExampleClient_ValidateState/RecipeDigest/VerifyCatalog/PublishEvidence/VerifyEvidence, ExampleVerifyBinaryAttestation.

🟠 Major — Example_resolveFromSnapshot: the facade never derives criteria from the snapshot, so this prose is false and the demo loop is dead code.
Mechanism: ResolveRecipeFromSnapshotWithOptions takes the caller's Criteria verbatim (toInternalCriteria(criteria) in aicr.go) and uses snap only to build the constraint evaluator — nothing populates criteria from the snapshot. The example sets criteria={Intent:"training"} and WithSnapshotCriteriaRelaxation(DimensionIntent), marking intent as stated. Coverage only reports specified dimensions as uncovered, and relaxDerivedCoverage (relax.go) clears only dimensions that are uncovered AND not stated. Intent is the sole specified dimension and it's stated → RelaxedDimensions is always empty → the for _, dim := range result.RelaxedDimensions loop at line 205 can never fire. "derive criteria from it" (L169) and "the rest came from the snapshot" (L175) do not describe what happens: there is no "rest" in the criteria, and the facade has no snapshot→criteria derivation entry point at all.
Blast radius: the flagship snapshot example teaches a wrong mental model and ships an unreachable demonstration. Independently confirmed by @yuanchen8911.
Fix: set the derived dimensions explicitly in criteria (e.g. {Service:"eks", Accelerator:"h100", Intent:"training"}) while passing only DimensionIntent as stated, so relaxation is actually reachable — and reword to say the caller supplies all criteria; the facade never reads them from the snapshot.
There was a problem hiding this comment.
Fixed in 09850c63 — see the reply on @yuanchen8911's thread for the full detail, since you found the same defect independently.
I took your suggested fix directly: criteria now carries Service and Accelerator as derived values alongside the stated Intent, with only DimensionIntent passed to the option, so relaxation is reachable. The prose now says the caller supplies all criteria and that the facade has no snapshot→criteria derivation entry point.
Your "blast radius" framing is the part I want to acknowledge: the unreachable loop was the visible symptom, but the wrong mental model was the real cost, and that is what the rewritten godoc targets.
There was a problem hiding this comment.
Correcting my earlier reply — the fix was incomplete, now resolved in ccc9c3b7.
I followed your suggested shape ({Service: eks, Accelerator: h100, Intent: training}, stating only intent) but did not check whether those criteria actually fail coverage. They do not — they resolve cleanly, so RelaxedDimensions stayed empty and your "demo loop is dead code" finding was only half addressed.
Now {Service: kind, OS: ubuntu, Intent: inference} with only DimensionIntent stated, verified against the real catalog to produce relaxed=[os]. The suggestion was right; I picked values that did not exercise it.

🟠 Major — ExampleClient_CollectSnapshot omits three required fields; against "a reachable cluster" (as its own comment promises) it fails at the API server.
Mechanism: AgentConfig{Namespace, Cleanup} leaves Image, JobName, and ServiceAccountName empty. toInternalAgentConfig (translate.go) is a pure field copy; facade CollectSnapshot forwards to DeployAndCollect, which validates only ClusterConfigPath and Namespace (snapshotter/agent.go — its own comment there notes "the CLI always supplies a default, so this is the SDK-caller path"). The empty strings flow raw into the Job and RBAC objects (k8s/agent/job.go, rbac.go), so the API server rejects an empty metadata.name / empty container image (the empty ServiceAccount is created first, so that's the first rejection). The CLI only works because pkg/cli/snapshot.go supplies flag defaults the facade does not share.
Blast radius: every integrator copying this canonical example hits an opaque K8s rejection deep in Deploy; CI never catches it (needs a cluster). Independently confirmed by @yuanchen8911.
Fix: set Image, JobName, and ServiceAccountName in the example (and note they're required on the SDK path) — or, better, default them in the facade to mirror the CLI so the SDK path isn't a foot-gun.
There was a problem hiding this comment.
Fixed in 09850c63, and I took the "or, better" half seriously.
The example now sets all three, with a godoc section explaining why they are required on the SDK path. The integration guide had the same gap — its agent block set Namespace, Image, and ServiceAccountName but omitted JobName — so that is corrected as well.
On defaulting them in the facade: I agree that is the real fix, but it is a behavior change and this is a documentation PR, so smuggling it in here would be the wrong shape. Filed as #2256 (linked to the epic), laying out both options — default to mirror the CLI, or fail closed with a coded error naming the field. It notes that the CLI derives the image from the binary version via defaultAgentImage(), which the facade already has through WithVersion, so option 1 is tractable.
Your point that CI can never catch this — it needs a cluster — is why I did not treat documenting it as sufficient.

There was a problem hiding this comment.
🟠 Major (net-new) — "LoadRecipe does NOT accept an HTTP(S) URL" is factually false and contradicts a sibling doc in this same package.
Mechanism: LoadRecipe → recipe.LoadFromFileWithProvider → serializer.ReadFileBytesWithKubeconfigContext, which special-cases only cm://; every other path goes to NewFileReaderWithContext, which explicitly downloads http:///https:// URLs (pkg/serializer/reader.go). There is no recipe-specific rejection of URLs anywhere in that chain — LoadRecipe does accept an HTTP(S) URL. And RecipeDigestOptions.Path in this very package documents "a path, an HTTP(S) URL, or a cm://... URI" (verify.go), with RecipeDigest using the identical loader — so the comment is self-contradictory. (The second clause — "kubeconfig is consulted only for the cm:// form" — is correct.)
Blast radius: a false negative capability claim in a canonical example. An integrator either needlessly avoids a working feature or builds a wrong threat model ("recipe inputs can't be network-sourced"). This is precisely the prose-vs-behavior mismatch this PR exists to prevent.
Fix: replace with the accurate form already used for LoadSnapshot/RecipeDigest — "path accepts a local file, an HTTP(S) URL, or a cm://namespace/name ConfigMap URI; kubeconfig is consulted only for the cm:// form." (If URL-sourced recipes are genuinely undesired, that's a code change adding a rejection, not just a comment.)
There was a problem hiding this comment.
You are right, and this one is mine twice over — fixed in 09850c63.
The original text said "Path, URL, or cm://", which was correct. In the previous review round I "corrected" it into being wrong, because I verified by grepping ReadFileBytesWithKubeconfigContext for http, saw only the cm:// branch, and stopped there — without following NewFileReaderWithContext, which explicitly downloads http:// and https:// (reader.go:208-216). A narrower check than the claim it was supporting.
Your self-contradiction catch confirms it independently: RecipeDigestOptions.Path in this same package documents "a path, an HTTP(S) URL, or a cm://namespace/name ConfigMap URI" and RecipeDigest uses the identical loader.
Restored to the accurate form you suggested. And no, URL-sourced recipes are not undesirable — RecipeDigest depends on that path — so this is a comment fix, not a code change.
The general lesson I am taking: compile-only examples pin signatures, so LoadRecipe(ctx, "recipe.yaml", "") compiles perfectly whether its comment describes reality or its opposite. Prose is exactly what compilation cannot check, which is where all four of this round's defects lived.
Two were independently confirmed by both reviewers. Example_resolveFromSnapshot was the flagship example and it taught a wrong mental model. The facade never derives criteria from a snapshot — ResolveRecipeFromSnapshotWithOptions takes Criteria verbatim and uses the snapshot only for constraint evaluation and post-processing; nothing in pkg/client/v1 calls pkg/fingerprint. The example set only Intent and also declared it stated, so with coverage reporting only SPECIFIED dimensions, relaxation could never fire and the RelaxedDimensions loop was dead code. Now supplies service and accelerator as derived, states only intent, and says plainly that the caller supplies every dimension. ExampleClient_CollectSnapshot omitted Image, JobName, and ServiceAccountName. DeployAndCollect validates only Namespace; the rest land in the Job and RBAC objects verbatim, and nothing under pkg/k8s/agent defaults them, so an empty ServiceAccount name is rejected by the API server before the Job is created. The CLI works only because pkg/cli/snapshot.go supplies flag defaults the facade does not share. Set all three, and document that they are required on the SDK path. The guide's agent block was missing JobName for the same reason. Removing the foot-gun is tracked in #2256. ExampleClient_SignCatalog left OIDCResolve zero-valued, so SelectOIDCSource falls through to the interactive browser flow, which blocks on a human and mints an oauth2.sigstore.dev certificate that fails VerifyCatalog's issuer pin. Show the ambient-credential form and state that this is a release-CI flow. The godoc also overstated the signing guard: it covers key, Fulcio, Rekor, and tlog upload, but not the identity source, which is the asymmetry a caller is most likely to hit. ExampleClient_LoadRecipe claimed LoadRecipe does NOT accept an HTTP(S) URL. It does: ReadFileBytesWithKubeconfigContext special-cases cm:// and sends everything else to NewFileReaderWithContext, which downloads http:// and https://. RecipeDigestOptions.Path in this same package already documented that correctly. This was a regression I introduced in b7314e3 while 'fixing' the opposite error, from verifying one function without following the call. Signed-off-by: Mark Chmarny <mark@chmarny.com>

| A | Example_resolveFromSnapshot taught that the facade derives criteria from the snapshot. It does not, and the RelaxedDimensions loop was dead code |
Supply derived dimensions explicitly, state only Intent; rewrote the godoc to lead with what the facade does not do |
| B | ExampleClient_CollectSnapshot omitted Image, JobName, ServiceAccountName — an API-server rejection against any real cluster |
Set all three; documented that they are required on the SDK path; filed #2256 for the underlying foot-gun |
| C | ExampleClient_SignCatalog with zero-value OIDCResolve falls through to the interactive browser flow and emits a bundle VerifyCatalog rejects |
Show the ambient-credential form; state this is a release-CI-only flow; correct the overstated signing guard |
| D | "LoadRecipe does NOT accept an HTTP(S) URL" — false, and a regression I introduced last round | Restore the accurate form |
Each was verified against the code before fixing, not accepted on description. grep -n "fingerprint\." pkg/client/v1/*.go returns nothing, confirming A. No defaulting of the agent fields exists anywhere under pkg/k8s/agent or pkg/snapshotter, confirming B. NewFileReaderWithContext explicitly downloads http:///https://, confirming D.
Finding D is the one worth dwelling on. The original text was correct; I "fixed" it into being wrong in b7314e38 by grepping one function and not following the call it makes. A narrower check than the claim it was supporting — the same failure mode as the three rounds before it.
Two spillovers
Checking the guide for the same defects found that its agent block also omitted JobName. Fixed here. Its fingerprint section was already correct — it shows the escape hatch and the coupling — which is what made A's prose so clearly wrong by comparison.
The unattributed CI failure is identified
It is tests/releasepolicy — five tests spawning shell scripts with load-derived budgets. Not related to this PR: they pass in isolation, and they touch nothing I changed. Frequency on this branch is roughly 2 failures in 6 full runs; a clean main baseline in a scratch worktree passed. I would not call it settled from that sample, but it is a pre-existing flake rather than something this PR introduced. Latest make qualify: QUALIFY_EXIT=0.
Standing back
Four review rounds, and every finding has been the same class: prose asserting something the code does not do. The compiled examples raise the floor — they caught the TrustLevels ordering bug and the log.Fatal-after-defer mistake unaided — but they cannot check English, and English is where all of this round's defects lived. LoadRecipe(ctx, "recipe.yaml", "") compiles identically whether its comment is true or its exact opposite.
That is worth stating plainly in the PR rather than leaving implied, since the PR's framing is "documented code is compiled." It is compiled. It is not thereby true. The examples table already carries the Runs column and the file header already distinguishes executed from compile-only; I have not tried to claim more than that.
The previous fix corrected the prose but left the demonstration inert. eks/h100/training resolves cleanly against the embedded catalog, so coverage never fails, RelaxedDimensions stays empty, and the loop was still dead code — reachable in principle, never in fact. Verified by resolving those exact criteria: they succeed on the first attempt. Switched to kind/ubuntu with intent stated, which relaxes os because no kind overlay states one. Confirmed end to end against the real catalog: relaxed=[os], so the loop fires as its comment claims. The godoc now also names both silent ways to make the policy inert: naming every dimension you supplied, or leaving dimensions unset. Signed-off-by: Mark Chmarny <mark@chmarny.com>

Summary
Adds compiled
Example_*functions for the SDK's integrator surface, and closes the documentation drift #2029's acceptance criteria name.Motivation / Context
docs/integrator/go-library.mddocuments the facade well — each epic PR updated it as it landed. But nothing in the tree compiled any of it, so every snippet could rot silently, and the last four SDK PRs each shipped documentation defects caught only in review.#2029 states the requirement plainly: "The non-negotiable property is that something in CI compiles the documented code, so a facade change that breaks an example fails in our tree." That was entirely unmet — zero example functions existed.

Type of Change
Component(s) Affected
docs/,examples/)pkg/client/v1) — godoc and examples only, no behavior changeImplementation Notes
The examples caught a defect on their first run
Example_trustLevelsasserted the levels came back highest-first (verified, attested, unverified, unknown) — matching how the CLI help text presents them. They come back alphabetical:TrustLevels()' godoc is explicit — "sorted alphabetically (NOT by rank)" — so the example comment was wrong, not the function. Exactly the class this PR exists to catch, caught before merge instead of by an integrator sorting by position and treatingattestedas the highest level. The corrected example now documents both traps: the ordering, and that the list is not the full accepted set ("max"and""are valid and absent).Lint caught a second one: five examples had
log.Fatalafterdefer client.Close(), soClosenever runs. That is broken code integrators would have copied. All handling is nowlog.Print+return, with the reason recorded in the file header.What runs vs. what only compiles
Output:asserted): quick start, error codes, trust levels, criteria dimensions. Output is restricted to criteria strings and enumerations — never component counts or versions, which change as the catalog evolves and would fail unrelated PRs.aicr-config.yaml,snapshot.yaml). They still pin every signature, field, and option they touch.Example_committedConfigexists specifically to pin theLoadConfig→RecipeSource→LoadCatalog→RecipeCriteriaordering — the sequence that was unreachable until #2243, and that a reviewer caught me documenting wrongly in that PR.Drift closed

New section stating four things plainly: import
pkg/client/v1; report missing capabilities rather than routing around the facade; whatapi-diffguarantees and what it does not (signatures, not behavior — a function keeping its signature while changing what it does passes the gate); and that documented code is compiled.Deliberately not here
examples/integrator/program. sdk: integrator guide and runnable example for the Go SDK #2029 offers it as an option alongsideExample_*. TheExample_*half delivers the non-negotiable property at a fraction of the maintenance, and the standalone version's value is mostly the OCI flow, which is still in flight.Testing

No behavior change: the only non-doc, non-test edit is the package godoc comment.
