Assert primary release order against recipe DeploymentOrder in the helm, helmfile, and argocd TestGenerateReportsLayout tests, since Releases order is normative and none of the three constrained it. Extract fileApplication/fileAppOfApps constants in argocd.go so the Manifest path built from Release.Path can't drift from the literal GenerateFromTemplate writes to. Signed-off-by: Mark Chmarny <mark@chmarny.com>
…egression The two-component fixtures (cert-manager, gpu-operator) had DeploymentOrder equal to alphabetical order, so a Releases() regression that sorted by name instead of preserving deployment order would produce the same sequence and pass unnoticed. Add nfd as a third component with DeploymentOrder cert-manager, nfd, gpu-operator - non-alphabetical, and also nfd's real dependency position ahead of gpu-operator - in all three deployer packages.

…ut fixtures ComponentRefs declaration order matched DeploymentOrder in all three TestGenerateReportsLayout fixtures, so a regression that used declaration order instead of the recipe's DeploymentOrder (e.g. a dropped SortComponentRefsByDeploymentOrder call) would produce the same sequence and pass unnoticed. Declare components as gpu-operator, cert-manager, nfd while keeping DeploymentOrder at cert-manager, nfd, gpu-operator, so declaration order, DeploymentOrder, and alphabetical order are all mutually distinct.

Regenerates the five per-deployer layout manifests with `make bundle-layout-baseline` to admit bundle-info.yaml, which runDeployer now writes at every bundle root (#2758). Purely additive: one line per manifest, no removals, confirmed by diff review before staging. Signed-off-by: Mark Chmarny <mark@chmarny.com>

repoURL, targetRevision and appName were recorded unconditionally, so a helm bundle claimed a repoURL whose effect appears in none of its files, and argocd-helm — the deployer built for OCI publication — stamped the GitOps URL the CLI warns it ignores into the only place in the artifact that mentioned it. Scope the three to the deployers whose own files show them: all three for argocd, repoURL and targetRevision for flux, appName for argocd-helm, none for helm and helmfile. The fields are omitempty, so the keys vanish. argocd-helm keeps appName alone even though buildDeployer hands it RepoURL and TargetRevision: that chart is URL-portable, rewrites both into .Values directives, and writes both keys empty in its root values.yaml, which a sentinel render over the emitted tree confirms. The new test pairs each deployer with the settings it may record and fails when a deployer is added without declaring its own scoping; the key-name allowlist cannot catch this, since the key is legitimate and the pairing is what is wrong. Signed-off-by: Mark Chmarny <mark@chmarny.com>
The path guard tested filepath.IsAbs, which lets "../../../etc" through; filepath.Join(outDir, path) then Cleans the traversal away and resolves outside the bundle without failing. Switch to filepath.IsLocal, the same primitive deployer.IsSafePathComponent uses, which rejects both shapes and still accepts benign names like "foo..bak". Read never called the guard at all, so the untrusted side — a record that arrived from an OCI registry or a GitOps clone — was the unguarded one. Call it there too, after the kind and apiVersion checks. Read also accepted aicr.run/v1alpha2 through the shared stable-track predicate. BundleInfo shipped at its ADR-022 target with no alpha to retire, so such a document never legitimately existed; gate it on a BundleInfo-specific predicate instead. Also document that Write overwrites the caller's apiVersion and kind, which is what keeps the header out of a caller's hands. Signed-off-by: Mark Chmarny <mark@chmarny.com>
helm was the one deployer still spelling its entrypoint as a literal at both the write site and the reported Entrypoint, the drift relationship the fileApplication / fileChart / fileKustomization constants exist to close. Document two contracts the layout index newly exposes: Release.Component is undefined for a recipe that declares both a base name and a name ending in a reserved -pre / -post / -readiness suffix, because the deployers disagree on which one such a folder belongs to; and argocd-helm's release order is os.ReadDir's lexical sort, correct only while the NNN- prefix stays padded to three digits. Switch helm's layout assertion to slices.Equal, matching the other four deployers. Signed-off-by: Mark Chmarny <mark@chmarny.com>
The layout index is reported by deployers and never re-derived, which is why Entrypoint and Releases are fields on deployer.Output. layout.provenance was the exception: runDeployer stat'd dir/provenance.yaml. provenance.yaml is written only when a run vendors charts, and localformat.pruneStaleFolders removes NNN-<name>/ directories and nothing else. Bundling with --vendor-charts and then without, into the same output directory, left the first run's file in place; the stat then recorded layout.provenance beside build.settings.vendorCharts=false, indexing a file the second run neither wrote nor covered by its checksums.txt -- outside that run's attestation subject. Add deployer.Output.Provenance, set it in the four deployers that emit the file, and take the value from there. argocd-helm emits none and reports none. Signed-off-by: Mark Chmarny <mark@chmarny.com>
Read documents its input as having arrived from an OCI registry or a GitOps clone, then opened it with os.Open. deployer.SafeJoin cannot help: it is a lexical check over the constant "bundle-info.yaml" and never touches the filesystem, and validateRelativePaths inspects decoded fields rather than the entry being opened. A bundle carrying a symlink there fed up to MaxBundleInfoBytes of an arbitrary process-reachable file to the YAML decoder, through a newly exported public API. Mirror verifier.readBoundedFileContext: O_RDONLY|O_NONBLOCK|O_NOFOLLOW, ELOOP rejected as ErrCodeInvalidRequest, and a regular-file check on the opened descriptor. The size cap is unchanged. Signed-off-by: Mark Chmarny <mark@chmarny.com>
The row justified aicr.run/v1 with "starts at its target under §7, with no alpha to retire". That is §7's wording for a beta start -- the same clause the ComponentUpgrades row uses for v1beta1 -- and §7 explicitly excludes a v1 start from that preference, holding it to the GA-readiness bar instead. Left as written, the row is a citable precedent for shipping any new kind straight to GA. Target unchanged; the rationale now makes the argument the clause requires.

bundleInfoSettings copied b.Config.RepoURL() and friends, so a bundle built without --repo recorded nothing while the deployer had already baked its own placeholder into the tree: flux writes sources/gitrepo-github-com-your-org-your-repo.yaml with url: https://github.com/YOUR_ORG/YOUR_REPO.git, and the record omitted repoURL entirely. A consumer read that as "nothing was configured" when the bundle in fact ships a URL that must be replaced before it applies. Report the effective values from each deployer through deployer.Output.Source, the same way Entrypoint, Releases and Provenance are already reported, rather than re-deriving them in the bundler. That deletes the per-deployer switch that mirrored buildDeployer and could drift from it, and keeps each placeholder in exactly one place. argocd reports repoURL, targetRevision and appName; argocd-helm reports appName only, since the chart rewrites the other two into .Values directives; flux reports repoURL and targetRevision, and only in git mode, because OCI mode writes no GitRepository for either to appear in; helm and helmfile report none. The test now runs each real generator and greps the emitted tree for every recorded repoURL, so "already observable in the bundle" is an assertion rather than a claim. Signed-off-by: Mark Chmarny <mark@chmarny.com>
Four fixes to the same pair of functions, which parse and emit a file that travels through OCI registries and GitOps clones. Read accepted a header-only document: it checked kind, apiVersion and path syntax, and validateRelativePaths skips empty values, so a record with an empty build.deployer, no recipe digest and no entrypoint parsed clean. It also accepted any deployer string. Reject a missing build.deployer, build.recipe.path, build.recipe.digest or layout.entrypoint, reject a deployer config.ParseDeployerType does not know, and require name/component/path on any release present. An empty release list stays legal: a recipe that resolves to no components emits exactly that. Write followed a symlink planted after checksum.ValidateOutputRoot's preflight, truncating its target (CWE-59). Open with O_NOFOLLOW and confirm the descriptor is regular, mirroring Read and verifier.readBoundedFileContext. Both functions mapped every dead context to ErrCodeTimeout, so a deliberate Ctrl-C looked like the retryable environmental fault ErrCodeCanceled exists to distinguish; errors.IsTransient splits on exactly that. Write skipped the size limit Read enforces, so an oversize record shipped inside checksums.txt and the attestation subject and failed only on the consumer's side. Signed-off-by: Mark Chmarny <mark@chmarny.com>
The row said the schema is additive-only by construction with "omitempty throughout", which it is not: apiVersion, kind, build, layout and the release identifier fields are required by their tags. The narrower statement is the true one and carries the same weight — every optional field has omitempty, so the schema extends without breaking an existing reader.

Read decoded only the first YAML document, so a valid record followed by --- and a second document passed every check while the trailing content was never validated. Read is the untrusted path; it now requires io.EOF after the first decode. Write skipped the required-field check Read enforces, so an exported API caller could persist a record our own reader rejects. The Write-side check surfaced a test deployer that never set Output.Entrypoint, unlike every real one; the fixture is fixed rather than the check loosened.

🧭 Multi-persona review — bundle-info.yaml
Method: 4 independent persona reviewers (Correctness/Determinism · Security/Supply-chain · Domain/Architecture · Test-coverage) → adversarial senior meta-review, each finding re-derived from the resolved code at head 4fa1f68b, then reproduced empirically where checkable.
Tier legend: 🔴 Blocker · 🟠 Major · 🟡 Minor · 🔵 Nitpick
Overall assessment
Unusually careful, fail-closed work. All three security-relevant axes hold up:
- Path traversal — every path-bearing field validated by
filepath.IsLocalon both Write and Read. - Determinism —
MarshalYAMLDeterministicsorts map keys recursively; no timestamp/uuid/abspath; every slice is deterministically ordered → SLSA-reproducible. - Attestation integrity —
bundle-info.yamlis written afterGenerateand before the finalWriteChecksums, always present for all 5 deployers, so it lands inside the checksum/attestation subject (same handling asrecipe.yaml), fail-closed on any Write error.
The six claimed test gates all genuinely exist and test what they claim (bidirectional index-vs-tree check, reflection-based settings allowlist, order-triangulated layout tests ×5, per-deployer Source scoping). No blocker, no security defect, no determinism defect.
Recommendation: Approve with comments. The one actionable code defect is the false-green Read-side path-traversal test (🟠); the v1-maturity rationale is correct in its conclusion but rests on an incorrect omitempty justification worth fixing before a v1 freeze locks it in.
Confirmed non-issues (examined, refuted)
- Ancestor-symlink CWE-59 (raised by CodeRabbit): not exploitable —
SafeJoinjoins a single constant component (bundle-info.yaml) onto a trusted dir, so there is no attacker-controlled intermediate path element; the final-componentO_NOFOLLOW+ regular-file check is complete here, and stronger than the siblingrecipe.yaml/values.yamlwrites. - Path-field coverage — complete (all 5 fields, both directions).
- Determinism / SLSA reproducibility — sound.
- Attestation ordering / always-present — sound, fail-closed.
- Size caps — 1 MiB enforced on both Write (pre-write) and Read (
LimitReadermax+1); no unbounded reads. - Info leak — nothing recorded beyond values already baked into the bundle's own emitted manifests.
- Namespace consistency — agrees across deployers (injected folders resolve to the parent namespace).
- Release ordering — correct and test-triangulated per deployer.
header.goBundleInfo gate — correct; no deprecation obligation skipped (no alpha predecessor).- "What vs how" separation + layering — sound; no import cycle;
deployer.Outputcoupling is the right seam. - Settings allowlist (incl.
Serial,Components) — principled and complete; enforced by reflection.
Reviewer note: CodeRabbit's earlier rounds were folded in; the author had already addressed most (O_NOFOLLOW, write-side size cap,
validateRequiredFields,context.Canceledsplit).
Summary
| Tier | Count |
|---|---|
| 🔴 Blocker | 0 |
| 🟠 Major | 1 |
| 🟡 Minor | 4 |
| 🔵 Nitpick | 3 |
Recommendation: Approve with comments.
The parent-traversal and absolute-entrypoint cases in TestReadFailsClosed omitted the build block, so Read rejected them at validateRequiredFields before validateRelativePaths ran. Both asserted only the shared ErrCodeInvalidRequest, which the missing-field error satisfies, so each passed identically with a safe path substituted and the Read-side path check was uncovered. Give each case a complete record and assert on the message fragment, which is the only thing that separates the two rejections. Cover layout.provenance from both sides: its only producer is a --vendor-charts run, which needs upstream chart bytes. Compare the whole struct after a round trip instead of three fields, and give the fixture a non-nil TolerationSeconds so the record's one pointer field is serialized by a test at all. Add the Write(nil) guard case. Signed-off-by: Mark Chmarny <mark@chmarny.com>
omitempty governs only what the writer emits. Read uses KnownFields(true) and IsSupportedBundleInfoAPIVersion accepts only the stable group version, so a field a later binary adds under v1 is rejected by an already-shipped v1 reader, not ignored. Additive safety comes from section 3's rule that mixed pipelines running an older binary are unsupported. Lead the cell with the stronger basis instead: BundleInfo is a mechanical projection of settled deployer and config state rather than an authoring surface, which is why the authoring and config kinds sit at beta while the bundle-root outputs do not. Signed-off-by: Mark Chmarny <mark@chmarny.com>
Component is deployer-dependent when a recipe declares a component whose own name ends in -pre, -post or -readiness alongside the matching base name. Freezing that into an aicr.run/v1 schema without saying so leaves a future maintainer to rediscover it as an accident rather than a decision. No shipped registry component has such a name and the fix is additive, so the schema stays as it is. Say in both the Go doc comment and the bundling guide that a later minor may add an explicit discriminator and that the value for that collision is not stable until then.

Summary
Every bundle now carries
bundle-info.yamlat its root: a deterministic build record naming the deployer that produced it, theaicrbinary that produced it, the resolved bundler settings that shaped it, and an index of which Helm release landed in which directory.Motivation / Context
ADR-021 Decision 5 and #2528 both specify
upgrade-check's deployer handling on top of a premise that was not true: "a bundle records the deployer it was built with." Nothing recorded it.runDeployerwroterecipe.yaml,checksums.txtand the attestation files, and discardedb.Config.Deployer()at that exact call site. The deployer was recoverable only by guessing from layout (app-of-apps.yaml→ argocd), which is the guessing Decision 5 forbids — showing an Argo CD operator the imperative "delete legacy CRs" step is the failure deployer-scoping exists to prevent.This is the second half of #2753, which fixed the
recipe.yamlhalf of the same premise.Fixes: #2758

The bundler maps them; it does not rebuildNNN-<component>from the recipe, because that convention is the deployer's and flux does not use it at all.build.settingsis admitted by a rule, and a test enforces the rule. A setting appears only when its effect is already observable in the bundle's own files. Endpoints and security posture that never shape bundle content — Fulcio/Rekor URLs, certificate identity pattern, registry TLS posture, output target, the--configpath — are excluded by construction, as are free-form--setoverrides.TestSettingsKeysAreAllowlistedfails on any unlisted key, so the nextConfigaccessor cannot join the artifact by accident. This matters because the file is pushed to registries and committed to GitOps repos.Releases, not components. The index is keyed on Helm releases, so injected
-pre/-post/-readinessfolders each get an entry naming their parent incomponent. ADR-021 Decision 4's-premigratefolder lands in that shape with no schema change. There is deliberately no ordinal field: list position is normative, which avoids restating theNNN-prefix and avoids implying a sequencing flux does not perform (flux orders bydependsOn, a graph rather than a line).One thing worth a maintainer's eye. The ADR-022 row starts
BundleInfoataicr.run/v1. §7draws a sharp line here: the "no alpha to retire" shortcut covers a beta start and explicitly does
not cover v1, which "remains subject to the GA bar" — the introducing decision must establish that
the public contract is already ready for GA obligations. The row therefore argues that bar on its
merits rather than citing the shortcut: the schema is small and gated by tests (a reflection-based
allowlist over
build.settings, a frozen per-deployer layout baseline, a self-description test),every optional field is
omitemptyso it extends additively, and it ships inside the attestationsubject from day one, which is itself a forcing function for stability. If you read the GA bar as
unmet, beta is the cheaper direction to correct — v1 takes on deprecation obligations that only a
documented window undoes.
Two versions, deliberately.
metadata.versionis the binary that ranbundle;build.recipe.versionis the binary that resolved the recipe. They differ whenever an olderrecipe.yamlis bundled with a newer binary — previously the bundle recorded only the latter.Testing

Risk Assessment
build.settingsrecords what the deployer actually resolved. The admission rule is that asetting appears only when its effect is observable in the bundle's own files, and the deployer
reports it rather than the bundler re-deriving it — the same mechanism as
layout.entrypointandlayout.releases. In practice: helm and helmfile report none ofrepoURL/targetRevision/appName(their generators have no such fields); argocd-helm reports only
appName, because it ignores--repoand rewritestargetRevisionto a chart-version template; argocd reports all three; andflux reports
repoURL/targetRevisiononly in git mode, since--flux-oci-source-nameemits noGitRepositoryfor them to appear in. Defaults count as resolved values: a flux bundle built with no--reporecords theYOUR_ORG/YOUR_REPOplaceholder that itssources/gitrepo-*.yamlactuallycarries, rather than omitting the key and implying nothing was configured.
Pre-existing gap this surfaced, not fixed here.
provenance.yamlis the one bundle-root filewritten conditionally (only when charts are vendored) and never pruned —
localformat.pruneStaleFoldersremoves only
NNN-<component>/directories. So a reused output directory can carry a staleprovenance.yamlfrom an earlier vendored run, and with checksums enabled the next run already failsat inventory finalization with "bundle contains an unexpected file". This PR makes the build record
honest about it (provenance is now reported by the deployer that wrote it, not inferred from a
directory stat) but does not prune the file.
helm.goalready removes a staleundeploy.shfor thesame reason; a matching
os.Removeis the obvious follow-up. Tracking separately.Rollout notes: Purely additive to the bundle. Bundles built before this change have no
bundle-info.yaml;bundleinfo.ReadreturnsErrCodeNotFoundnaming that reason so consumers treat it as a real state rather than falling back to guessing the deployer from directory layout. No CLI flag, no API change, no OpenAPI change — server-generated bundles acquire the file through the samerunDeployerpath.Checklist
