📝 WalkthroughWalkthroughAdded ADR-021 for component upgrade safety. The design defines directional semver transition records, five verdicts, deployer-specific migration steps, strict gating, downgrade handling, offline artifact comparison, optional cluster scanning, ownership-aware reporting, generated migration releases, dual-version wrappers, Helm inventory reads, CRD handling, and KWOK/UAT validation. Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: 🟡 Moderate · up to The ADR proposes a machine-readable upgrade-safety contract, but its current schema and examples can still allow missing warnings or unsafe transition handling because verdict semantics, version detection, migration lifecycle, and component coverage are inconsistent. The document is not merge-ready until these contract gaps are corrected or explicitly accepted. Suggested reviewers: 🚥 Pre-merge checks | ✅ 4✅ Passed checks (4 passed)

In `@docs/design/021-component-upgrade-safety.md`:
- Line 255: Define the cross-component transition schema in the ADR, including
the field for affected components, how each component’s versions are sourced,
which component owns the verdict and migration steps, and how dependency cycles
are detected or handled. Update the YAML example and report behavior so coupled
components are explicitly represented and grouped consistently.
- Around line 385-397: Update the UAT design in “Decision 9: UAT covers upgrade
and rollback” to validate transition records, not only component health: run
upgrade-check, assert the selected safe/manual/reversible classification, and
execute listed manual steps where applicable. Map each real safe and reversible
record to a corresponding UAT transition, or narrow the documented claim to
runtime health only.
- Around line 317-319: Update the ADR’s component-set change section and
acceptance criteria to explicitly define verdicts for added, removed, and
replaced components, including their gating behavior, and add corresponding
tests; alternatively, clearly state that these changes are outside this ADR.
Keep the semantics consistent with the matcher’s component-to-version comparison
and cover the related section also identified by the review.
- Line 277: Add language identifiers to the three fenced code blocks in the
component upgrade safety documentation, using text or console as appropriate to
satisfy markdownlint MD040.
- Around line 293-301: Update the lifecycle specification for the generated
-premigrate release near the KindLocalHelm/localformat behavior: define
source-version-aware selection for fresh installs and upgrades, idempotent
execution, cleanup when no longer applicable, and explicit rollback ordering for
both the migration and component releases, including their side effects. Clarify
how the directional source-to-target record controls these decisions and require
UAT coverage for both releases.
- Around line 423-448: Update the example to use the record-schema identifiers
rename-crs-gitops and rename-crs-imperative instead of rename-crs, and correct
the Helm-scoped output to state the accurate number of applicable steps (two)
unless a third defined step is added.
- Around line 343-350: Update the semver calibration and strict-mode decision
logic to treat unassessed 0.x minor transitions, such as 0.17.2 to 0.18.1, as
breaking boundaries that fail closed. Add an acceptance test covering this
transition and preserve the existing behavior for assessed and non-0.x
transitions.
- Around line 319-321: Update the “Whether a cluster scan runs” and “Where the
from table comes from” discussion to avoid calling Helm release inventory ground
truth for live cluster state. Describe cluster input as Helm’s last recorded
release metadata and rendered manifest, or add an explicit live-resource drift
check and define how it affects upgrade verdicts.
- Around line 115-118: Update the upgrade precondition describing Skyhook status
so that, when no rollout is active and no nodes are in progress, it accepts
complete, paused, and disabled states; retain the restriction against upgrading
while a rollout or node work is in progress.
- Around line 285-311: Clarify the migration phase semantics around the
generated `-premigrate` release and the transition record: define whether
`phase: pre-upgrade` affects hook annotations, folder/release ordering, or
metadata, and specify the intended behavior for Argo CD’s repeated `PreSync`
execution. Document that migration hooks must be idempotent and include cleanup
handling for reruns.
- Around line 259-267: Expand the affectedResources scan specification to define
exact ownership markers and precedence for AICR, Helm, Argo CD, and Flux,
including how conflicting or partial metadata is classified. Document the
expected outcomes for owned, unmanaged, and partially managed resources, and add
tests covering each deployer’s ownership detection.
- Around line 353-373: Define the component-version matching precedence: use the
aicr.run/component-version annotation for AICR-generated wrappers, and fall back
to the upstream Helm release Chart.yaml.version when the annotation is absent.
Update the matcher and add tests covering both annotated wrappers and direct
third-party charts.

- Line 9: Update the scope statement in the ADR to acknowledge that Decision 4
changes the bundle layout by adding the -premigrate release folder and Decision
7 changes generated Chart.yaml fields and annotations. Describe the
compatibility and rollout impact of these observable artifact contract changes,
rather than stating that the bundle layout or deployer contract remains
unchanged.
- Around line 120-131: Update the deployer values in the rename-crs-gitops and
rename-crs-imperative records to use the canonical identifiers from the public
bundle API, replacing argocdhelm with argocd-helm and localformat with the
supported deployer identifier. If these records require internal aliases,
normalize them before filtering so every listed deployer remains selectable.
- Around line 285-291: Add the hooks field to the transition schema, or replace
its usage with the established steps field. Document the hook path base,
deployer filtering, relationship to -premigrate, and required validation failure
when a referenced migration file is missing; keep filesystem implementation
details out of the ADR.
- Around line 335-347: The rollback gating logic must honor the matched
transition’s reversible: false setting instead of treating a missing reverse
record as an ordinary unknown result. Update the reverse-check path and its
result classification to produce a blocking irreversible outcome, or consult the
forward record when no reverse record exists, while preserving strict-mode
behavior for genuinely unknown transitions. Add acceptance coverage for rollback
of an explicitly irreversible transition.
- Around line 63-68: Revise the ownership section to separate generated wrapper
authorship from input-content provenance. Define an explicit registry-owned
versus user-owned classification for each Kustomize source, including
git-sourced and local-path inputs, and state the corresponding versioning and
migration-hook owner instead of inferring ownership from source location alone.
- Around line 172-180: Update the verdict well-formedness requirements for the
report contract: require manual transitions to include executable steps, require
safe transitions to have no steps, and define the allowed relationship between
reversible and reversibleNotes so rollback claims cannot be misleading. State
the observable validation failures at the requirement level while leaving
detailed failure-path test matrices to implementation work.
- Around line 130-135: Update the rename-crs-imperative migration to define an
idempotent adoption action for each deployer: validate
nodewright.nvidia.com/mirrored-from and apply the required Helm ownership
metadata before the primary release. Document the Helm and helmfile command,
Flux HelmRelease dependency, and Argo CD PreSync or equivalent ordering and
cleanup behavior.

I think this is a good design and adds incrementally more value to what aicr provides that nothing else does: that high level view of what it means to move between versions. Keeping it up to date and correct over time will be a challenge.
Some open question opinions:
- escape hatch flag Does this need a flag? The command
upgrade-checkimplies this is a parallel command torecipeorbundlemeant to provide information to the caller. Not one that is within it and would block. - upgrade-check as the name seems fine to me. It is likely the most common behavior and from the example clearly the behavior with the most information. There is barely anything that can be supplied for rollbacks.
- values drift detection is its own issue and is really on the PR that is setting the new version and values not at
upgrade-checktime.

📋 Multi-persona review — ADR-021 Component Upgrade Safety
Method: 4 independent persona reviewers (Domain/Architecture, Correctness/grounding, Docs/Editorial, Operability/Supply-chain) → an adversarial senior meta-reviewer that re-derived every finding from the resolved doc + codebase. 19 raised → 14 confirmed, 5 down-tiered, 0 refuted. Anchored to 0c7fc921.
Tier legend: 🔴 Blocker · 🟠 Major · 🟡 Minor · 🔵 Nitpick
Note: @ayuskauskas already reviewed (L63, L217) and CodeRabbit posted inline. Several majors below independently land on CodeRabbit's lines (noted inline); the L63 finding echoes @ayuskauskas — credit to them.
Overall assessment
Genuinely strong ADR — tightly reasoned, honest about its own unproven claims, and well-grounded in real code (I verified ~15 file:line citations; all accurate except the deployer-id strings in C1/C2). The five-verdict model, directional records, and "ownership not mechanism" boundary are sound.
The confirmed majors are not "reject" issues — they're under-specifications and fail-open gaps to resolve before the implementation PRs. Three of them are worth folding into the ADR text now because they contradict the doc's own headline thesis of fail closed by default (L23):
- D1 / O2 / D2 are three doors into the same fail-open: a known-destructive rollback (D1), a breaking
0.xminor bump (O2), and a removed/replaced component (D2) each resolve tounknown/no-verdict and pass strict mode. Since nodewright — the worked example — is itself0.x, O2 hits the central use case. - O1 is a concrete supply-chain hole: the BOM/pin tooling walks only
manifests/, so the newmigrations/Job image the ADR says "must appear in the BOM" would ship unpinned and unscanned.
Confirmed non-issues / adjustments
- All code citations verified accurate —
ownsCRDs(components.go:129-154),writer.goranges,chart.yaml.tmpl:19,builder.go:231,validate.go:845,root.go:38,flux.go:994,.settings.yaml:84, kwok script lines, and counts (23 AICR-authored / 11 manifest-only / 43 assertFile / 4-crds). Only the deployer-id strings were wrong. - MD040 bare fences down-tiered → Nitpick: MD040 is not enforced by any repo gate (docs CI checks filenames + MDX only), so it's cosmetic, not a lint failure.
- Helm-v4 license risk down-tiered → Nitpick: the ADR already characterizes the policy correctly and defers it appropriately under Consequences + Open Questions.
Summary
| 🔴 Blocker | 🟠 Major | 🟡 Minor | 🔵 Nitpick |
|---|---|---|---|
| 0 | 7 | 5 | 7 |
Recommendation: 🟢 Approve as a proposal. Fold D1 / O1 / O2 into the ADR text now; track D2–D5 as decisions to firm up before their implementation-plan steps; C1/C2/Doc1/Doc2 are quick text fixes. Inline comments follow.

🔵 Nitpick — ADR-021 number may collide; renumber at merge (self-flagged)
L7 already self-documents the ADR-020/021 numbering collision (020-recipe-resolution-policy branch plus PR #2334 claiming ADR-020) and instructs 'Renumber at merge if 021 is also taken'. Legitimate merge-time reminder.
Blast radius: Merge-time coordination — filename and every 'ADR-021' reference would need updating if 021 is claimed.
Fix: At merge, confirm the next free ADR number and renumber the file + references if 021 is taken.

Agreed, no action, merge-time reminder. Still contested: the docs/adr-020-resolution-policy branch and PR #2334 both claim 020. Will confirm the next free number at merge and renumber the file and references if needed.

Read this closely — the reasoning is careful, particularly the fail-open analysis around directionality and unversioned, and Decision 9's point that rollback is not the inverse of upgrade.
Four comments, two threads:
Versioning — aicr.run/v1alpha1 isn't a version this repo accepts (line 97), and the record loader in Implementation Plan step 2 should fail closed on an unknown apiVersion rather than degrading to unknown. Related: I've opened #2373 (ADR-022) recording per-kind artifact maturity, which is where that question should have had an answer.
Gating — a suggestion to reuse ADR-019's qualification-gate shape so a pin bump is treated as a re-qualification event. That gives the verdicts a reviewable basis and, I think, answers your coverage-ratchet open question from the authoring side.
Besides the comments from @CodeRabbit and @njhensley; the v1alpha1 line is the only thing I'd call a defect.

| ### Decision 6: Strict by default, semver-calibrated |
There was a problem hiding this comment.
Structural suggestion: consider deriving these verdicts from an explicit gate checklist, reusing the shape ADR-019 established.
ADR-019 admitted k8s-aibom to the registry only after upstream v1.2.0 passed five categories of gate — release/supply chain, Helm and Kubernetes lifecycle, security and privacy, operational safety, and AICR qualification. What it doesn't cover is what happens next: nothing re-runs those gates when a pin moves. They ran once, for one release. That's the same seam this ADR stands on, approached from the other side.
The two are already describing the same things in different vocabularies:
| ADR-019 gate | This ADR |
|---|---|
| "CRD conversion, migration, and retention behavior is documented for the selected API" | the nodewright CRD rename, verbatim |
| "deterministic install, update, rollback, and uninstall ownership" | Decision 9, rollback is not the inverse of upgrade |
"renders consistently through helm, helmfile, argocd, argocd-helm, flux, localformat" |
the deployer-scoped steps in Decision 2 |
If a version bump is treated as a re-qualification event, the transition record becomes the natural carrier for which gates were re-checked and what they returned:
safe— applicable gates re-pass at the target versionmanual— gates pass, but a lifecycle gate needs operator stepsblocked— a gate fails and steps can't remediate itunknown— gates not run for this transition
This is complementary to Decision 9, not a replacement. UAT gives a tested claim for transitions you actually run; a gate checklist gives a reviewable basis for records authored before a UAT lane exists. You already name the gap — "every safe and every reversible: true is an unverified human assertion" — and this narrows what "unverified" means in the interim.
Two ADR-019 conventions worth stealing regardless: it separates gates from preferences explicitly ("A namespace- or label-scoped informer is a qualification preference, not a gate"), and it records accepted residuals as decisions rather than leaving them to be discovered.
ADR-019 isn't referenced anywhere in this ADR today. Even a pointer would help the two read as one system.
There was a problem hiding this comment.
Adopted, though not quite in the shape you proposed, so worth checking I read you right.
New Decision 11 says the authoring checklist is based on ADR-019s five gate categories, treating a pin bump as a re-qualification event, and it now references ADR-019 which the ADR did not do at all before. But the checklist itself lives in docs/contributor/, not in the ADR: a checklist evolves and embedding it would mean amending a decision record to add a bullet.
What I did not take is deriving the verdicts from the gate results. The verdict vocabulary stayed as is, with the checklist feeding the author rather than defining the enum. If you meant the stronger version, say so and I will reopen it.

🔁 Re-review — ADR-021 Component Upgrade Safety (delta)
Method: Re-review of my prior 4-persona review (@ 0c7fc921, 17 findings) against the fix commit a781ced9 ("correct ADR-021 deployer ids, semver calibration, and step schema"). Every prior finding was re-derived against the resolved doc and dispositioned; an adversarial senior meta-reviewer agreed with all 17 dispositions and confirmed the 6 net-new findings. Anchored to head a781ced9.
Tier legend: 🔴 Blocker · 🟠 Major · 🟡 Minor · 🔵 Nitpick · ✔️ Addressed · ◐ Partial · ✖️ Not addressed
Other human reviewers (not duplicating): @ayuskauskas — broadly positive. @mchmarny — flagged
aicr.run/v1alpha1(L97) as the one real defect; I verified and confirm it (inline below). CodeRabbit's latest round independently lands on the coupling schema and the precondition mismatch.
Prior-feedback status (17)
| # | Tier | Finding | Status |
|---|---|---|---|
| P7 | 🟠 | Strict-mode fails open for 0.x — 0.y minor is breaking | ✔️ Addressed — Decision 6 L357-359 now treats a 0.x minor as a breaking boundary |
| P9 | 🟡 | argocdhelm not canonical |
✔️ Addressed — argocd-helm at L121/L233/L395 |
| P11 | 🟡 | "renders three steps" should be two | ✔️ Addressed — L462 |
| P12 | 🟡 | Example step id not in record | ✔️ Addressed — record uses rename-crs in both groups; L231 permits reuse |
| P16 | 🔵 | Bare code fences (MD040) | ✔️ Addressed — ```text at L289/307/339 |
| P1 | 🟠 | reversible:false unreachable on rollback |
◐ Partial — 0.x calibration now fails the cited rollback closed, but the reverse path still surfaces generic unknown, never the authored reversible:false. Residual → 🔵 |
| P10 | 🟡 | localformat / "six deployers" |
◐ Partial — count fixed except one stray "six" (see inline L323) |
| P14 | 🔵 | Schema never consolidated | ◐ Partial — L186-188 consolidates only hooks; affectedResources still scattered |
| P2 | 🟠 | Add/remove/replace has no matcher verdict | ✖️ Not addressed |
| P3 | 🟠 | Cross-component coupling has no schema field | ✖️ Not addressed (CodeRabbit L188 concurs) |
| P4 | 🟠 | Online mode has no upstream-chart version source | ✖️ Not addressed |
| P5 | 🟠 | -premigrate conditionality/idempotency/rollback-order |
✖️ Not addressed |
| P6 | 🟠 | BOM walks only manifests/ → migrations/ image unpinned |
✖️ Not addressed |
| P8 | 🟡 | Verdicts ship before ownsCRDs gap fix | ✖️ Not addressed |
| P13 | 🔵 | Chart-author vs registry-contributor | ✖️ Not addressed |
| P15 | 🔵 | Helm-v4 license risk (optional de-risk) | ✖️ Not addressed — stands, low stakes |
| P17 | 🔵 | ADR-021 number collision | ⏳ Standing — self-flagged L7, merge-time action |
Score: 5 addressed · 3 partial · 8 not addressed · 1 standing. The fix commit cleanly closed the semver fail-open (P7 — the central one) and all the text-fix minors/nitpicks. The five still-open Majors (P2–P6) are the design under-specifications my prior review already flagged as "firm up before the implementation-plan steps," not proposal-blockers.
Net-new findings (6, all confirmed)
Six new inline comments follow — the most consequential:
- 🟡 N1 (L484): AC-1 still gates on a "major boundary" while the fixed Decision 6 gates on a "breaking boundary" (major or 0.x minor) — coding AC-1 verbatim reintroduces the fail-open P7 just closed.
- 🟡 N2 (L433): the worked-example precondition still says "complete" while the record now allows paused/disabled.
- 🟡 N3 (L97): the example stamps
aicr.run/v1alpha1, which the header validator rejects (v1alpha2is the supported version). (mchmarny's defect, verified.) - 🟡 A1 (L188): the new
stepsByDeployergrouping can render a steplessmanualverdict for a deployer the author forgot — worse thanunknown.
Summary
| 🔴 Blocker | 🟠 Major | 🟡 Minor | 🔵 Nitpick |
|---|---|---|---|
| 0 | 5 open (P2–P6) | 3 open + 4 new (N1/N2/N3/A1) | 6 open + 2 new (N4/A2) |
Recommendation: 🟢 Approve as a proposal — the fix commit strengthened the standing verdict. Worth folding in now as quick text fixes: N1, N2, N3, N4 (N3 especially — a rejected apiVersion in the canonical example is actively misleading). P2–P6 remain design gaps to firm up before their implementation-plan steps. A1 is the one genuinely new correctness gap the fix commit introduced and is cheap to close in the well-formedness rule.

- Around line 460-484: Update the migration example’s helm/helmfile transition
around stepsByDeployer and rename-crs to reference adopt-mirrored-crs.yaml
through hooks, defining execution before the component release so the
mirror-created NodeWright receives the required ownership metadata;
alternatively, make the manual adoption step explicitly perform that action
before rewriting manifests.
- Around line 359-372: Update the UAT safety model so a safe verdict is only
accepted for version pairs actually covered by the executed lane. Either require
coverage across every source-target pair supported by a semver record or
restrict safe records to explicitly tested transitions, and ensure the matcher
cannot report safe for an untested pair.
- Around line 301-307: Revise Decision 6 to resolve the mismatch between the
opt-in upgrade-check command and its fail-closed claims: either define
upgrade-check as a required pre-upgrade gate for every supported deployer,
including the required invocation path, or narrow the ADR to describe it as
advisory and remove claims that imply upgrades are protected by default. Keep
the documented exit-status behavior consistent with the chosen policy.

🔁 Re-review — ADR-021 Component Upgrade Safety (round 3, head 6a845d7d)
Method: Delta re-review of my two prior reviews (17 findings @ 0c7fc921 + 6 @ a781ced9 = 23) against the 4 new commits. The doc grew 558→667 lines — new Decisions 10 (coverage gate), 11 (authoring workflow), 12 (pins-not-releases), a full field-reference table, a fail-closed loader clause, and an Implementation-Plan reorder. Every prior finding was re-derived against the resolved head.
@lockwobr replied on ~30 inline threads with a resolving SHA for each, and the fixes check out. @mchmarny's
v1alpha1point and @ayuskauskas'sstepsByDeployergrouping were both adopted and credited in the doc.
Disposition of 23 prior findings
✔️ Addressed (17): P1 (reversible reframed as advisory, never gates a verdict — the fail-open premise is gone), P6 (migration content moved to manifests/migrations/ so the recursive BOM walk + pin test catch it with no tooling change — the root-cause fix), P7, P8 (ownsCRDs reordered to Implementation-Plan step 1), P9–P14 (incl. the field-reference table for P14 and the Decision 1 rewrite "the remedy is the record" for P13), P16, and all six round-2 findings N1–N4, A1, A2 (AC-1 breaking-boundary, example precondition, v1alpha2 + fail-closed loader + new AC-8, stray "six" gone, deployer-partition rule with remainder semantics).
◐ Documented as deliberate Open Questions (3): P2 (added/removed component, L606) and P3 (cross-component coupling, L605) are now explicit Open Questions — the right move for a proposal. P5 (-premigrate emission) resolved via Decision 12's to-range bounding; Job idempotency / rollback-pair ordering stay light.
⏳ Standing (2): P15 (Helm-v4 license, open question), P17 (ADR-number, merge-time).
New / still-open findings (4, inline)
- 🟡 F1 (L338): Decision 7 still says
aicr.run/component-versionis "the only field the matcher reads," but upstream charts carry no such annotation, so online mode has no version source for most of the registry (prior P4). Acknowledged on-thread but not recorded in the doc — add an Open Question with parity to P2/P3. - 🔵 F2 (L645): Consequences still lists "no coverage ratchet" as an unmitigated risk that Decision 10 now resolves.
- 🔵 F3 (L579): Testing-Strategy UAT row over-claims
reversiblevalidation that Decision 9 deliberately walked back. - 🔵 F4 (L649): "Strict-by-default … unassessed major bumps" drifts from Decision 6's rename and understates the 0.x-minor case.
Summary
| 🔴 Blocker | 🟠 Major | 🟡 Minor | 🔵 Nitpick |
|---|---|---|---|
| 0 | 0 | 1 (F1) | 3 (F2/F3/F4) |
Recommendation: 🟢 Approve. A genuinely strong response — 22 of 23 prior findings resolved or converted to documented Open Questions, including the two sharpest (P6's BOM-walk root-cause fix, P8's reorder). The only substantive leftover is F1: record the online-upstream-version gap in Open Questions for parity with P2/P3. F2–F4 are one-line rewrite-residual cleanups. Nothing blocks merge.

Re-review (delta @ 43ee3e6c) — since my earlier (force-push-dismissed) approval, the branch was rebased and 6 new substantive commits landed (+143/−25, doc only), reworking hooks-on-safe, upstream version source, cross-component coupling, add/remove/replace, rollback scope, and the coverage gate.
Legend: 🔴 Blocker · 🟠 Major · 🟡 Minor · 🔵 Nitpick · ✔️ Addressed · ⊘ No longer applicable
Overall
Unusually responsive revision — it closes every open thread from my prior rounds by deciding the questions rather than deferring them:
hooksonsafe(my 🟠 Major): now allowed on any verdict, with a clean rationale — a hook is AICR doing the work, so forbidding it would force an already-automated transition tomanual.- Upstream version source (my 🟠 Major, and last round's "largest unresolved gap"): resolved with a two-branch rule — read
aicr.run/component-versionwhen present, else the release's own chart version. - Cross-component coupling (my 🟠 Major): converted to an explicit non-goal, described in steps, with a persuasive cost argument (278
dependencyRefsedges, ~none imply migration). - add/remove/replace (my 🟠 Major): fully modelled — Added/Removed/Replaced table + top-level
replacesfield +kgateway → agentgatewayworked example. - Coverage gate hardening:
verifiedBy-required-on-safe+ forward-reach ban + inter-record gap check together make the gate measure assessment, not just coverage — closing the blanket-safeloophole. - Old D7 list break (my last 🟡): fixed; the paragraph is now standalone.
Checked the most likely regression from the new required field: no concrete safe YAML example is missing verifiedBy — the only verdict: safe snippet is the deliberate anti-pattern the rule rejects, and all worked examples are manual.

| **Three things make the gate measure assessment rather than coverage.** [Decision 2](#decision-2-transition-records) forbids a record's `to` from reaching past the current pin, so every bump forces an author back into the record; it requires `safe` to name what verified it; and the report states the span a verdict covers, so a wide `from` is visible in review. Any one alone is evadable. Together, the cheapest record that clears the gate is one somebody edited, substantiated, and can be seen to have overreached. | ||

| **The gate measures coverage; `verifiedBy` measures assessment.** On its own, a coverage assertion is satisfiable by a blanket `safe` record spanning a component's whole history, which is why [Decision 2](#decision-2-transition-records) requires `safe` to name what verified it. The two are a pair: the gate creates the obligation to have a record, and `verifiedBy` stops the cheapest record from being a lie. |

🔵 Nitpick — Decision 10 states the coverage-vs-assessment point twice in adjacent paragraphs
L508 ("Three things make the gate measure assessment rather than coverage") already names verifiedBy as one of its three levers and argues coverage-alone is evadable; L510 ("The gate measures coverage; verifiedBy measures assessment") restates that same thesis one paragraph later.
Blast radius: Reads as saying the same thing twice back-to-back.
Fix: Fold L510's one unique clause ("the two are a pair…") into L508 and drop the restated heading.

Summary
Adds ADR-021, a proposal for making "is this component version transition safe?" a machine-readable question with a machine-readable answer, attached to the artifact that encodes the version change.
Motivation / Context
Today AICR pins a chart version in
recipes/registry.yaml, generates a bundle, and the operator applies it. Nothing in the artifact says whether the transition from the version they are running to the version they are about to install is safe, requires manual work, or is unsupported. That knowledge exists in upstream release notes, a maintainer's head, or a GitHub issue, and none of it is machine-readable.The failure mode is silent: regenerate a bundle after a pin bump, apply it, discover the breaking change as an outage.
The nodewright
skyhook.nvidia.comtonodewright.nvidia.comrename is the worked example throughout, including the awkward part where AICR itself authors five of the affectedSkyhookCRs.Fixes: N/A

Proposal only, no code. Nine decisions; the load-bearing ones:
recipes/upgrades/<component>.yaml, mirroring the existinghealthCheck.assertFilepattern, keyed by semver ranges, with deployer-scoped steps. Under GitOps the nodewright rename and legacy deletion collapse into one atomic commit; under imperative Helm they are two steps in a load-bearing order.blockedrather than composed, because composing nodewright's two records would imply a jump that destroys data is fine. Widening a block is the escape hatch, so there is no flag anyone can forget to set.safe,manual,blocked,unknown,unversioned. The last two are distinct because their remedies differ: author a record versus pin something comparable.-premigraterelease, mirroring the-postinjectionlocalformatalready performs, so it works uniformly across manifest-only, Kustomize, and upstream-chart components.helm listcannot work, because it does not return the chart annotations the matcher reads.Claims the ADR does not yet stand behind are flagged in the doc rather than smoothed over:
