Adds AWS rendering and validation regressions for required scalar and collection options, blank CLI JSON input, both network ACL directions, SNS attribute names, and the VPN type value.

The generated package and docs now come from #5174 on main. This PR changes only integration tests; scraper and generator fixes were merged separately.

Validation: authoritative AWS generation and integration CI passed; scoped test formatting passed. Final head 3231a4a passed the required Linux pipeline, Windows build, CodeQL, analyzers, Native AOT, and all reviews. The remaining macOS job was cancelled after the PR was merged. Local full AWS build and semantic formatting reached the existing 2 GB guard earlier; expensive validation runs in CI.

Refs #4337, #5149, #5158, #5164, #5169.

Code review

Reviewed the AWS required-options parsing change (AwsCliScraper.cs, regenerated AwsEc2CreateKeyPairOptions/AwsEc2TerminateInstancesOptions + facade signatures, and the new AwsCliScraperTests regression test).

Verification performed:

  • Read the full diff and cross-checked GetRequiredSynopsisOptions/AwsSynopsisOptionPattern against the existing ParseOptions/AwsOptionPattern section-scanning pattern already used for the OPTIONS block — the new synopsis scan reuses the same "find header, find next ALL-CAPS header, slice between" idiom, so it's consistent with established parsing conventions in this file.
  • Confirmed the primary-constructor-for-required-options pattern ([property: CliOption("--key-name")] string KeyName) is a pre-existing, already-used code path (e.g. AwsS3CpOptions, several ModularPipelines.Azure options), not a novel risk introduced here.
  • Confirmed via PublicAPI.Shipped.txt (src/ModularPipelines.AmazonWebServices/PublicAPI.Shipped.txt) that CreateKeyPairAsync/TerminateInstancesAsync and their options types are not in the shipped API surface, so the GeneratedApiCompatibilityPreserver's baseline/compat logic correctly does not block this change, and the "BREAKING CHANGE" called out in the PR description isn't actually breaking for any published consumer.
  • Built tools/ModularPipelines.OptionsGenerator/ModularPipelines.OptionsGenerator.slnx (Release) — succeeded, 0 warnings/0 errors.
  • Ran AwsCliScraperTests — all 9 tests pass, including the new Required_Options_Are_Preserved_In_Generated_Apis regression test, which asserts both the scraper-level IsRequired flags and the generated source text for the options records and IAwsEc2 interface.

No correctness bugs, CLAUDE.md violations, or architectural concerns found. The synopsis-parsing heuristic has a known, acceptable edge case (it skips unbracketed mutually-exclusive groups like --a | --b since it filters on " | "), but that's a pre-existing style of limitation matched to the narrow scope of this fix (two commands) and not a regression.

The exact-head P1 is valid. Required false must render --no-protected-from-scale-in.

PR #4358 already owns the generalized implementation this branch needs: CliFlagAttribute.NegatedName, runtime/source-generator propagation, paired AWS switch scraping, analyzers, and regression coverage. Duplicating that cross-cutting contract here would create overlapping public API and generator changes. I am deferring this PR until #4358 lands; then this branch can rebase and retain the paired switch metadata while applying its required-option parsing.

Rebased onto current main and resolved the generator conflict while preserving both the numeric-enum guard and required-option parsing. Required list constructor parameters retain GroupValues = true, with a focused regression.

Validation:

  • focused Required_Options_Are_Preserved_In_Generated_Apis: 1/1 passed
  • OptionsGenerator Release build: passed, 0 warnings/errors
  • scoped formatting: passed
  • AWS solution build: local 2 GB guard stopped the process tree at 2,126 MB; not retried per repository rules
  • live AWS regeneration is unavailable on Windows because the scraper's help pipeline invokes cat; in-memory production-generator regression covers the reconciled output

The exact-head boolean-negation finding remains intentionally dependent on #4358, as noted earlier.

Code review

Reviewed the current head (32ef65e) of the required-AWS-options change: AwsCliScraper.cs's new GetRequiredSynopsisOptions synopsis scan, the two new regexes (AwsSynopsisOptionPattern, AwsRequiredBooleanAlternativePattern), the regenerated EC2/Autoscaling options records and facade signatures, and the new Required_Options_Are_Preserved_In_Generated_Apis regression test.

What changed since the last review pass: the branch was rebased onto current main (resolving a generator conflict) and a GroupValues = true regression was added for the required list constructor parameter. The logic itself — required-marker detection from OPTIONS descriptions plus unbracketed-option detection in SYNOPSIS — is unchanged from what was already verified.

Verification performed on this pass:

  • Walked GetRequiredSynopsisOptions end-to-end against the new test fixtures (autoscaling set-instance-protection, ec2 terminate-instances, ec2 create-key-pair): section slicing (SYNOPSIS → next ALL-CAPS header), the [-prefixed skip for optional args, the --x | --no-x boolean-alternative capture, and the generic " | " skip for other mutually-exclusive groups all behave as intended against the fixture text.
  • Confirmed the primary-constructor conversion (AwsEc2CreateKeyPairOptions(...), AwsEc2TerminateInstancesOptions(...), AwsAutoscalingSetInstanceProtectionOptions(...)) correctly moves only the newly-required members into the constructor and leaves optional members (CliInputJson, GenerateCliSkeleton, Force, etc.) as settable properties — no duplicated members between the constructor and body.
  • Confirmed the facade method signature changes (options param losing its = null default) are consistent with these three APIs being unshipped (not referenced elsewhere in this diff, and the PR description/prior review already confirmed they're absent from PublicAPI.Shipped.txt), so this isn't actually a breaking change for any published consumer despite the "BREAKING CHANGE" note in the description.
  • Checked the previously-raised P1 (required-false booleans need to render --no-protected-from-scale-in) against the current diff: it's still not implemented here, but the author's 2026-08-31 comment explains this is intentionally deferred to #4358, which owns the general NegatedName mechanism this would need — reasonable scoping rather than an oversight, so not re-flagged as blocking.
  • No CLAUDE.md files exist under src/ModularPipelines.AmazonWebServices/ or tools/ModularPipelines.OptionsGenerator/ beyond the root CLAUDE.md, and none of its build/tooling guidance applies to this diff.

No correctness bugs or design concerns found. The regex-based synopsis scan is a pragmatic, narrowly-scoped extension of the existing "find header, find next ALL-CAPS header, slice between" idiom already used for the OPTIONS section in this file, so it doesn't introduce a new parsing strategy to maintain — reusing it here is the right call over building a separate synopsis-specific parser.

Code review

Reviewed the current head (3ea4b558) of this PR against the last two claude review passes (both CLEAR, at 92860f62 and 32ef65e1). Since 32ef65e1, two new commits landed: fix(aws): support alternate required input (b3a499a2) and test(aws): cover required negative flag (3ea4b558). These add a genuinely new feature — "alternate input mode" support (FromCliInputJson/ForCliSkeleton factories) for AWS commands that accept --cli-input-json/--generate-cli-skeleton in place of their required options — which wasn't present in the previously-reviewed heads, so it needed fresh verification rather than being covered by the prior CLEAR verdicts.

Verification performed:

  • Cloned the PR branch and diffed b3a499a2 / 3ea4b558 against 32ef65e1: only OptionsClassGenerator.cs and AwsCliScraperTests.cs changed — no generated *.Generated.cs files were touched in either commit.
  • Confirmed OptionsClassGenerator.SupportsAlternateInputModes (tools/ModularPipelines.OptionsGenerator/.../OptionsClassGenerator.cs:595-601) is satisfied by the checked-in AwsEc2CreateKeyPairOptions/AwsEc2TerminateInstancesOptions/AwsAutoscalingSetInstanceProtectionOptions commands (required options, no required positionals, --cli-input-json present), and ran the PR's own AwsCliScraperTests.Required_Options_Are_Preserved_In_Generated_Apis test — it does produce the new private-ctor + FromCliInputJson/ForCliSkeleton factory shape when generation runs.
  • Grepped the shipped AwsEc2CreateKeyPairOptions.Generated.cs, AwsEc2TerminateInstancesOptions.Generated.cs, and AwsAutoscalingSetInstanceProtectionOptions.Generated.cs — none contain FromCliInputJson/ForCliSkeleton; they're still the plain primary-constructor form from the earlier commits in this PR.

Findings:

  1. Stale generated artifacts — the new feature isn't actually shipped (blocking). src/ModularPipelines.AmazonWebServices/Options/AwsEc2CreateKeyPairOptions.Generated.cs:23 (and the other two files above) were never regenerated after b3a499a2 added the alternate-input-mode generator logic. Combined with this PR's earlier removal of the options = null default on CreateKeyPairAsync/TerminateInstancesAsync/SetInstanceProtectionAsync, a caller who wants to drive these calls purely via --cli-input-json (the scenario this feature exists for) has no FromCliInputJson factory to use and must supply the now-required positional args directly — the feature is untestable/unusable in the actual shipped API even though the generator and its unit test both prove the logic works. This needs a regeneration pass (or the PR's "AWS solution build" test-plan checkbox needs to include running the generator + committing the diff) before merge.

  2. AWS-specific strings hardcoded into the shared generator (design concern). SupportsAlternateInputModes/HasOption in OptionsClassGenerator.cs:595-604 hardcode "--cli-input-json" and "--generate-cli-skeleton" by literal string match in the tool-agnostic generator shared by every CLI integration (Docker, kubectl, Terraform, ...). Any other scraper whose CLI happens to expose an option with one of those exact names would silently pick up AWS-shaped alternate-constructor generation it never opted into, and extending this escape-hatch pattern to another AWS flag (or another tool's equivalent) means editing shared codegen rather than scraper-supplied data. Better fit: have AwsCliScraper set a flag/marker on CliCommandDefinition (e.g. SupportsAlternateInput or a list of "bypasses required options" option names) so the generator stays a generic consumer of scraper metadata instead of encoding AWS's CLI vocabulary directly.

  3. Duplicated section-boundary parsing (minor maintainability). AwsCliScraper.GetRequiredSynopsisOptions (Scrapers/Cli/AwsCliScraper.cs:456-473) re-implements the same "find ^SECTION\s*$, then the next all-caps header, else end-of-text" logic already used by ParseOptions (:332-343) for the OPTIONS block. Worth factoring into a shared ExtractSection(string helpText, string sectionName) helper so a future fix to section-boundary detection doesn't need to be applied twice.

  4. Boolean-alternative ordering gap (edge case, low severity). AwsRequiredBooleanAlternativePattern (Scrapers/Cli/AwsCliScraper.cs:607) only matches --foo | --no-foo ordering. If an AWS command's SYNOPSIS ever lists the pair as --no-foo | --foo, the regex misses it, the line falls through to the generic " | " skip, and --foo is left IsRequired=false — silently under-detecting requiredness. Given this is scoped to the three commands this PR targets today (verified all list the positive form first), it's not blocking, but worth a follow-up if the synopsis scan gets reused for more commands.

Item 1 is the one I'd treat as blocking: the PR description and generated test both describe a working alternate-input-mode feature, but the artifacts a consumer would actually compile against don't have it. Items 2–4 are design/maintainability suggestions for follow-up, not blockers.

Code review

Summary: This PR teaches the AWS options generator to detect [required]/unbracketed-synopsis options and (when a command also exposes --cli-input-json/--generate-cli-skeleton) to emit an explicit required constructor plus FromCliInputJson/ForCliSkeleton static factories instead of the plain primary-constructor form. It regenerates AwsEc2TerminateInstancesOptions, AwsEc2CreateKeyPairOptions, and AwsAutoscalingSetInstanceProtectionOptions/related facades, and adds a scraper unit test with a synthetic AWS help-text fixture.

Blocking: the committed generated files don't match what the new generator actually produces for these commands

OptionsClassGenerator.SupportsAlternateInputModes (tools/ModularPipelines.OptionsGenerator/src/ModularPipelines.OptionsGenerator/Generators/OptionsClassGenerator.cs:450-456) triggers the new required-constructor + FromCliInputJson/ForCliSkeleton factory path whenever a command has at least one required option, no required positional arguments, and exposes --cli-input-json or --generate-cli-skeleton. All three commands touched by this PR (ec2 terminate-instances, ec2 create-key-pair, autoscaling set-instance-protection) satisfy every one of these conditions against the real, currently-installed AWS CLI (2.36.29) — verified directly, not inferred: I built ModularPipelines.OptionsGenerator.slnx, then ran AwsCliScraper + OptionsClassGenerator against the actual aws ec2 terminate-instances help / aws ec2 create-key-pair help / aws autoscaling set-instance-protection help output. For all three, RequiredOptions.Count > 0, zero required positionals, and both --cli-input-json/--generate-cli-skeleton present — so SupportsAlternateInputModes is true, and the freshly generated code contains the new private AwsEc2TerminateInstancesOptions(), public static … FromCliInputJson(...), and public static … ForCliSkeleton(...) members.

None of that is present in the files actually committed in this PR (e.g. src/ModularPipelines.AmazonWebServices/Options/AwsEc2TerminateInstancesOptions.Generated.cs): they still use the plain positional-record form (public record AwsEc2TerminateInstancesOptions(IEnumerable<string> InstanceIds) : AwsOptions), with no FromCliInputJson/ForCliSkeleton factories and no private parameterless constructor.

So the shipped .Generated.cs files are stale relative to the generator code in the same PR — they look like they were produced by an earlier version of OptionsClassGenerator before GenerateRequiredConstructor/GenerateAlternateInputFactories/SupportsAlternateInputModes were finalized, and weren't re-regenerated afterward. Concretely this means:

  • The "alternate input modes" feature this PR advertises (per the PR's own CodeRabbit summary: "Generated APIs now support alternate input modes through FromCliInputJson and ForCliSkeleton") doesn't actually exist yet for any of the three commands this PR touches — it's only exercised by the new synthetic-fixture unit test, not by the real generated artifacts.
  • The scheduled generate-cli-options.yml workflow (or a manual --use-cli-first run) will produce a different diff than what's in this PR the next time it runs against the same generator code, since a true regeneration diverges from what's committed here.

Suggested fix: re-run the AWS generation step for ec2/autoscaling (e.g. --tools aws --use-cli-first) against the final generator code and commit the actual output, rather than the pre-final-changes snapshot. It'd also be worth adding a regression check that catches this class of drift going forward — e.g. a test that regenerates a couple of real, currently-installed-CLI-backed commands (not just the synthetic fixture) and asserts the checked-in .Generated.cs is byte-identical, so "generator changed but artifacts weren't regenerated" fails CI instead of just producing a surprise diff on the next scheduled run.

Design note: required properties lose their non-nullability in the new alternate-input-mode path

In the pre-existing primary-constructor path, a required option becomes a non-nullable primary-constructor parameter/property (e.g. [property: CliOption(...)] IEnumerable<string> InstanceIds). In the new GenerateRequiredConstructor/GenerateAlternateInputFactories path (OptionsClassGenerator.cs:462-512), required options are instead emitted as ordinary nullable auto-properties via the existing GenerateProperties/GenerateProperty (public string? KeyName { get; set; }), only assigned by the explicit constructor. The constructor still forces callers to supply a value up front, but the property's declared type no longer reflects that guarantee — e.g. options.KeyName.Length needs a null-forgiving operator/null check even though KeyName is required, and nothing stops options with { KeyName = null } later. Since this is exactly the kind of thing the primary-constructor path already gets right, it'd be more consistent (and preserve the compile-time guarantee this PR is trying to add) to generate required properties as non-nullable in this path too, matching the primary-constructor property style.

No other correctness issues found in the scraper regex changes (AwsSynopsisOptionPattern, AwsRequiredBooleanAlternativePattern) or the new test — the added unit test itself passes and correctly encodes the intended shape for its synthetic input.

Review

This PR is the authoritative full AWS CLI 2.36.46 regeneration (19,332 commands, up from 18,920) plus two new regression test files. Given the ~22k changed files are almost entirely generated output, I diffed pr-head/ against main at the non-generated layer first (generator/scraper source under tools/ModularPipelines.OptionsGenerator, hand-written code under src/ModularPipelines.AmazonWebServices outside Options/Services/Enums/Generated, and .csproj), confirmed those are byte-identical to main, and then spot-checked the generated files tied to the two open review findings from prior rounds and to the new tests.

Both previously-open P1 findings are fixed at this head (6ebf554074):

  • AwsSnsSetTopicAttributesOptions.Generated.csAttributeName is a required string, not an enum; Policy/DeliveryPolicy/FifoThroughputScope all render as plain string values. Matches AwsEnumBoundaryTests.Sns_Attribute_Names_Render_As_Required_Strings.
  • AwsEc2CreateVpnGatewayOptions.Generated.csType is a required string, so the single ipsec.1 value renders without a bullet marker. Matches AwsEnumBoundaryTests.Single_Vpn_Type_Renders_Without_A_Bullet_Marker.
  • Repo-wide grep for the bullet-marker artifact (EnumValue("o")) across all of src/ModularPipelines.AmazonWebServices returns zero matches, so this wasn't just patched for the one reported case.

Spot-checked required-argument generation, which lines up with AwsRequiredCollectionTests:

  • AwsEc2CreateNetworkAclEntryOptions/DeleteNetworkAclEntryOptions/ReplaceNetworkAclEntryOptions all keep [CliFlag("--egress", NegatedName = "--ingress")] on a required, non-nullable bool Egress constructor parameter — both directions render correctly.
  • AwsEc2TerminateInstancesOptions/AwsAutoscalingSetInstanceProtectionOptions materialize the required IEnumerable<string> before validating and throw ArgumentException only when every element is null, while still accepting (and rendering) a mix of null/non-null values — matches the "reject all-null, keep non-null" test pair.
  • FromCliInputJson on AwsEc2TerminateInstancesOptions/AwsEc2CreateKeyPairOptions/AwsAutoscalingSetInstanceProtectionOptions all use ArgumentException.ThrowIfNullOrWhiteSpace, so blank/whitespace JSON throws as asserted.

Coverage sanity check: Aws.CommandCoverage.json command count moved 18,920 → 19,332 with the version bump; I confirmed at least one command that could plausibly have been renamed/dropped (delete-service-linked-analyzer) is still present, consistent with the PR description's "no baseline removals" claim. I did not exhaustively diff all ~19k command names against main (impractical by hand at this file count); that's the kind of check the repo's own command-coverage regeneration gate is built for.

Housekeeping: no PublicAPI.Shipped.txt/PublicAPI.Unshipped.txt files were added for the AWS package, consistent with the repo rule that generated CLI packages don't track those baselines. The new Generated/Aws.Generation.json provenance file (tool version + source/tree hashes) is new but additive and matches the description's provenance claim.

CI status at review time: Fast fail, Classify changes, analyzers, CodeQL javascript-typescript/actions, and trim and Native AOT are green; full pipeline (ubuntu-latest), build (windows-latest), build (macos-latest), CodeQL csharp, and this claude-review job are still in progress. No failing checks observed. Per repo policy, pending checks aren't a blocker — just flagging that the full-pipeline/build results weren't available yet when I looked.

No actionable findings from this pass. Given the iteration history on this PR, nice work converging the enum/bullet-marker and ingress/egress fixes with source-generator-level regression coverage rather than hand-patching the generated files.

The enum findings are fixed in 6ebf554, but fresh generated-output review found a separate masking defect: seven MaxResults page-count properties carry SecretValue because their descriptions mention token values. The authoritative generated PR #5168 was closed per repository policy; source issue #5169 tracks the detector fix.

This PR remains blocked until that source fix merges and a fresh authoritative AWS snapshot is incorporated. The new masking finding remains unaddressed in the current snapshot; no generated file will be hand-edited.

Please review current head 6ebf554. The prior summary reports automatic reviews paused. The enum fixes and rendering tests are now pushed; the separately reported pagination masking defect remains tracked by #5169, and blocks merging until fresh output replaces the closed generated PR #5168.

The incremental checkpoint could not be recovered (comment 5693581311). Please review current head 6ebf554 and keep the summary compact. The pagination masking defect is already tracked in #5169 and remains a merge blocker.

The secret-metadata blocker in #4367 (comment) is fixed in 88ede22, now confirmed on the remote PR head. Source fix #5170 merged first; fresh authoritative output #5174 then passed generation, integration CI, and review and was merged into main. This branch includes that exact package/docs snapshot and latest main.

The generated audit confirms removal of 31 numeric metadata and 20 public enum SecretValue annotations, with genuine credential masking retained. No generated files were repaired by hand. The final PR diff is two regression-test files, 94 added lines. CI and reviews are running on the new head.

Code review

Recap: since the last `claude` review pass (head `6ebf5540`, CLEAR), the branch only picked up merge/regeneration commits from `main` (`fb697de5` merge, `0138629c` chore: update AWS CLI options, `2000e7e4` merge authoritative AWS output from #5174, `88ede22b` merge `main`). `gh pr diff` confirms the PR's actual changeset is unchanged: still exactly the two new test files, `test/ModularPipelines.AmazonWebServices.UnitTests/AwsEnumBoundaryTests.cs` and `AwsRequiredCollectionTests.cs`. No production or generated code is touched.

I re-verified every assertion in both files against the current generated option classes in `src/ModularPipelines.AmazonWebServices/Options/` and the shared `CommandArgumentBuilder`/`CommandModelProvider` rendering pipeline at this head: constructor signatures, thrown exception types (`ArgumentNullException` vs `ArgumentException`), enum members, flag negation names (`--egress`/`--ingress`), and null-filtering for grouped collection options all match the current generated output exactly. Tests correctly live in the matching `ModularPipelines.AmazonWebServices.UnitTests` project, and nothing generated was hand-edited.

Non-blocking nit

`AwsEnumBoundaryTests.cs:21` — `Single_Vpn_Type_Renders_Without_A_Bullet_Marker` doesn't exercise any bullet-marker-stripping logic. `Type` is a plain `string?` ([CliOption("--type")]), and `CommandArgumentBuilder.GetSingleValue` echoes string values verbatim — there's no runtime doc-bullet-stripping step; that would only happen at generation time in `tools/ModularPipelines.OptionsGenerator`. So the test really just guards that `Type` stays a `string` rather than becoming an enum, a narrower guarantee than the name implies. Consider renaming it (e.g. `Type_Is_A_Plain_String_Not_An_Enum`) or, if guarding against bullet-marker regressions is the intent, moving that assertion to the generator's own tests where the stripping actually happens.

No blocking issues found.

CodeRabbit completed the full review of 88ede22 with no actionable findings. Its docstring warning reports 30 functions across five files, while the final diff contains two regression-test files and introduces no public library API. Descriptive test names and assertions state the contracts; no documentation change is needed for this test-only update.

Addressed the naming nit in #4367 (comment) with 3231a4a, confirmed on the remote PR head. The test is now Single_Vpn_Type_Renders_As_String, matching its generated-API/rendering guarantee. Bullet extraction remains covered by the generator regressions merged in #5165. Scoped formatting passed; assertions and behavior are unchanged.

@thomhurst The test name now states the generated API and rendering contract clearly. I will review the current head.

Code review

Recap: since the last claude review pass (head 88ede22b06, CLEAR with one non-blocking naming nit), the only change is the current head, 3231a4a304, which renames Single_Vpn_Type_Renders_Without_A_Bullet_Marker to Single_Vpn_Type_Renders_As_String in AwsEnumBoundaryTests.cs. That addresses the nit exactly as suggested: the name now states what the test actually guards (Type stays a plain string) instead of implying bullet-marker-stripping logic that doesn't run at this layer.

I re-confirmed the PR's full changeset is still just the two new files — AwsEnumBoundaryTests.cs and AwsRequiredCollectionTests.cs in test/ModularPipelines.AmazonWebServices.UnitTests/ — with no production or generated code touched. I re-verified every assertion against the current generated option records in src/ModularPipelines.AmazonWebServices/Options/ and enums in .../Enums/, and against the rendering pipeline in CommandArgumentBuilder.cs:

  • AwsEc2CreateVpnGatewayOptions(string Type) / AwsSnsSetTopicAttributesOptions(string TopicArn, string AttributeName) — constructor signatures and --type/--topic-arn/--attribute-name option names match exactly.
  • AwsEc2CreateNetworkAclEntryOptions / AwsEc2DeleteNetworkAclEntryOptions / AwsEc2ReplaceNetworkAclEntryOptions — all three still emit [CliFlag("--egress", NegatedName = "--ingress")], matching the both-directions test.
  • FromCliInputJson on all three alternate-input types still calls ArgumentException.ThrowIfNullOrWhiteSpace, matching the blank-JSON rejection test.
  • AwsEc2CreateKeyPairOptions(string KeyName) / AwsAutoscalingSetInstanceProtectionOptions(..., string AutoScalingGroupName, ...) still use ArgumentNullException.ThrowIfNull, matching the null-rejection test.
  • AwsEc2TerminateInstancesOptions(IEnumerable<string> InstanceIds) still throws ArgumentException for an all-null collection, and CommandArgumentBuilder.GetCollectionValues still skips null items before rendering — so [null!, "i-example"] renders as ["--instance-ids", "i-example"], matching the last test in the file exactly.

No blocking issues found. No open findings remain from prior review rounds.
