feat(health): render evidence signer class in recipe-health matrix - #3757
Add a Signer class column to docs/user/recipe-health.md that shows the allowlist class (first-party, community, partner) of each recipe's committed evidence pointers. This replaces the interim prose note that said the class was not rendered.
Motivation / Context
Readers could not tell from the matrix who signed a recipe's evidence without cross-referencing recipes/evidence/allowlist.yaml by hand.
pkg/evidence/index.SignerClasses() returns the distinct classes of each recipe id's committed pointers from the embedded pointers.yaml, in first-party, community, partner order. An unknown class fails closed with ErrCodeInternal. The generator stays hermetic and offline.
Rows join to pointers by attestation.RecipeNameFor, the same id --require-evidence checks. pkg/health.ComboHealth gains an omitempty Profile field (the resolved name=value selection) so a profiled row reads the pointer for its declaration-default value (<recipe>-gpustack-<value>). Without it, the GKE gke-default pointer would be missed and an unprofiled base pointer would be credited to a profiled resolve.
The join lives in tools/health, not pkg/health, because pkg/evidence/attestation pulls in the sigstore dependency tree.
Signer class is its own column. The Evidence cell keeps its deep-link and stays free for ADR-009's deferred freshness token.
First-party UAT ingests evidence directly and commits no pointer, so first-party cannot appear in this column today. The doc says an em dash means "no committed pointer," not "first-party." Every committed pointer is currently community, and no partner is onboarded.
Regenerating the matrix also picks up catalog drift already on main (74 to 81 recipes, updated coverage counts).
docs/contributor/evidence-publishing.md now tells publishers to run make recipe-health-docs after adding a pointer.
Testing
make generate
make recipe-health-docs
go test ./pkg/evidence/index/ -run TestPointersYAMLMatchesTree
make qualify
make qualify passed: total coverage 86.3% (threshold 83%), golangci-lint 0 issues, MDX checks, e2e, and API compatibility all green.
Coverage vs origin/main:
pkg/health: 100.0% → 100.0% (+0.0%)
pkg/evidence/index: 84.7% → 86.5% (+1.8%)
tools/health: 83.7% → 84.6% (+0.9%)
New tests: TestSignerClassesOf, TestSignerClassesCoversEmbeddedIndex, TestComputeComboProfile, TestSignerClassCell, TestRenderMatrixSignerClass, and TestRunRendersProfiledPointerClass (end to end over the embedded catalog for a profiled GKE recipe).
Risk Assessment
Low — Isolated change, well-tested, easy to revert
Medium — Touches multiple components or has broader impact
High — Breaking change, affects critical paths, or complex rollout
Rollout notes: N/A. The change adds a doc column and an omitempty report field. tools/testgrid-link-check reads presence.yaml, not the doc table, so the extra column does not affect it.

Add a Signer class column to docs/user/recipe-health.md. tools/health
reads each recipe's committed pointer classes from the embedded
pkg/evidence/index and joins rows by the same recipe id that
--require-evidence checks, so a profiled row reads the pointer for its
declaration-default value. pkg/health records the resolved profile
selection on each combination to form that id.
Replace the interim note about pointer classes with a description of
the column.

Walkthrough
The health generator now loads signer classes from the embedded evidence index and displays them in a new matrix column. It derives recipe evidence IDs using the selected profile when present. The health result includes the selected profile as name=value after successful resolution. The documentation explains signer-class display and updates the generated matrix from 74 to 81 recipes.
NVIDIA/aicr#3755 — Adds a recipe pointer and signer entry that the health generator can read.
NVIDIA/aicr#3720 — Adds recipe pointer entries and a signer entry that the health generator can read.
Suggested reviewers:njhensley
Merge Risk: Minimal · previous review fd190
No actionable issue remains in the signer-class display or its documentation; the change is mergeable after normal checks.
Security architecture risk: Minimal · up to fd190
The change displays committed signer metadata without granting new privileges or weakening evidence requirements. Profile-aware matching preserves evidence identity, and the documentation distinguishes signer attribution from signature verification and runtime validation.
Retained concerns
No architecture-level concerns identified.
Security review details
Security Blast Radius
inferred — The assessed new exposure is recipe/source-class attribution in generated documentation and selected-profile metadata in health reports. The inspected path does not confer credentials, tenant access, deployment authority, or evidence-verification authority.
Trust Boundaries and Controls
observed — The existing evidence requirement remains a committed-pointer presence check restricted to embedded recipe provenance. The new display lookup does not replace that check or turn attribution into signature verification; this presence-only behavior predates the PR.
observed — Normal profile identity comes from resolver-selected metadata and is passed through the shared attestation identity builder. Profile validation remains separate from displaying a class, and no inspected enforcement consumer accepts ComboHealth.Profile as authority.
Resilience and Maintainability Implications
observed — Repeated lookups allocate fresh maps and cloned class slices, preventing callers from mutating the cached pointer inventory through the new API. Index-load or unknown-class failures abort the generator before it creates or truncates output. Existing output publication behavior is otherwise unchanged.

Explanation
The changes support issue #2877. They load signer classes from committed evidence pointers, join profiled rows to the checked pointer ID, test the lookup and rendering, regenerate the recipe-health matrix, and update evidence-publishing guidance. No unrelated change is demonstrated.
Full details: Linked Issues check
Explanation
Issue #2877 requires the trust class in the Evidence cell alongside its deep link. The current renderer keeps evidenceCell link-only and adds a separate Signer class column in tools/health/markdown.go. The generated document follows that separate-column format. The class lookup, profiled-ID handling, tests, and regenerated matrix satisfy the data and generation parts, but they do not satisfy the required Evidence-cell placement.
Resolution
Render the signer class in the Evidence cell with the deep link, using a format that remains compatible with ADR-009's deferred freshness token. Update the generated matrix and golden expectations. Keep the no-pointer representation and profiled-pointer lookup behavior documented and tested.

Review — PR #3757 feat(health): render evidence signer class in recipe-health matrix
Method: balanced; 3 persona passes (correctness, domain & architecture / API contract, tests & docs), adjudicated by a fresh senior agent against head 67c7397.
Tier legend: 🔴 Blocker · 🟠 Major · 🟡 Minor · 🔵 Nitpick · ✅ Confirmed non-issue
Other reviews: CodeRabbit only (two trivial doc-wording notes and a linked-issue check asking for the class inside the Evidence cell). Not re-raised here. The PR body explains the choice of a separate column. No human reviews yet.
Overall assessment — Approve with comments
The new column takes the signer class from the embedded pointer index, using the same attestation.RecipeNameFor id that --require-evidence checks. An unknown class fails closed. The committed table matches what the generator produces at this head, byte for byte. One doc sentence is wrong for rows whose only pointer is under a non-default profile value. The rest are nitpicks.
Inline comments
🟡 Minor — F1: "An em dash means the recipe has no committed pointer" is wrong for three rows docs/user/recipe-health.md:50
evidenceID builds only the row's declaration-default id (<recipe>-gpustack-<default>). Pointers for other profile values are never read, and neither are base ids of profiled rows. Three rows render an em dash even though each has a committed community pointer under -gpustack-bundle-installer: gb200-gke-cos-inference-dynamo, gb200-gke-cos-training-kubeflow and gb200-gke-cos-training-slurm. Across the whole matrix, 10 of the 28 ids in pointers.yaml reach no row, in three groups:
Overlays with children get no row of their own, because rows are kept from presence.yaml only: gb200-eks-ubuntu-training, h100-gke-cos-training and h100-aks-ubuntu-training.
Base ids of profiled AKS rows: h100-aks-ubuntu-{inference-dynamo,training-kubeflow}.
The five gb200-gke -gpustack-bundle-installer ids.
Confirmed by running health.Compute and evidenceID over the embedded catalog at this head.
Consequence: on those rows, a reader takes "no committed pointer" for a fact when community evidence does exist for another profile value. That is the exact signal the column was added to show.
Fix: reword the bullet, e.g. "An em dash means no pointer is committed under this row's id. Pointers for other profile values, and for overlays that have no row, are not shown." Optionally add a test that every pointers.yaml id maps to a row or sits on an explicit not-rendered list, so new omissions are deliberate.
🔵 Nitpick — F2: ComboHealth.Profile is a name=value string that evidenceID splits straight back apart pkg/health/health.go:176
Compute joins SelectedProfile.Name and .Value with =, and tools/health parses the string back into a recipe.SelectedProfile. The field is now public through aicr.Client.ComputeHealth, so its shape gets harder to change later.
Fix: optionally carry the typed *recipe.SelectedProfile (still omitempty) and drop the parse.
Moving ClassFirstParty to the end of signerClassOrder leaves ./pkg/evidence/index and ./tools/health green. Swapping community and partner is caught. Today TestEmbeddedClassesAreAllowlisted keeps first-party pointers out of the index, so this is latent.
Fix: add a first-party entry to the "mixed" case.
The test asserts on h100-gke-cos-training-kubeflow's real pointers. An unrelated contributor PR that adds or reclassifies a pointer for that recipe would turn make test red. It is also the only end-to-end check that Profile reaches the rendered table, so the coupling may be deliberate.
Fix: optionally pick a profiled row with a pointer at test time, and assert that its cell matches SignerClasses() for its id.
✅ Confirmed non-issues
Class drift from allowlist.yaml: pointers.yaml takes its class from the allowlist, and TestPointersYAMLMatchesTree fails make test on any mismatch.
Profiled id: evidenceID and index.Check both go through attestation.RecipeNameFor, and the ids matched on every row that has a pointer.
Generated doc: regenerating at head (go run ./tools/health -deterministic) reproduces the committed block byte for byte. The move from 74 to 81 recipes is drift already on main.
API compatibility: Profile is an additive omitempty field. The CLI reads only Structure and LeafOverlay, no OpenAPI schema references ComboHealth, and testgrid-link-check reads presence.yaml.
Fallback to the unprofiled id when a profiled resolve fails (health.go:271): the mechanism is real but not reachable today. All 81 rows pass at head, and a failed row already shows fail or unknown in its Status cell.
Import boundary: no depguard rule restricts pkg/health or tools/health. The PR body's sigstore reason is inaccurate (pkg/evidence/index already imports attestation), but keeping the join in the renderer is still a sound placement.
Coverage and limitations
Source-inspected at the pinned head: all 9 changed files, plus RecipeNameFor, pointers.yaml, allowlist.yaml, the recipe-health-* Makefile targets, the refresh workflow, the depguard config and the ComboHealth consumers.
Ran on an export of the head:
the generator, followed by a byte-diff against the doc;
the focused new tests (all pass);
two mutation probes (dropping Profile from evidenceID fails the tests; reordering first-party does not);
a probe test listing every pointer id that no row renders.
Not run: full suite and lint.
The branch is BEHIND main. Main has since added gb200-nvke leaves, so the table will need regenerating after a rebase (advisory; the weekly refresh also covers it).
