Addressed both blocking generator findings. The metadata generator now matches root ModularPipelines.Module and root generic ModularPipelines.DependsOn, and the source-generator test infrastructure now models the v4 namespaces. Also rebased onto current main. Validation: core Release build passed (0 warnings/errors); ModuleMetadataGeneratorTests 24/24 passed; ModuleEventMetadataGeneratorTests 7/7 passed. The full source-generator test project hit the mandated 2 GB agent guard (exit 137), so it was not retried. |

Review: #4264 — reorganize namespaces
This is a large, mostly-mechanical namespace reorg (~3,800 files) plus a generator follow-up fix. I diffed with rename detection to isolate the ~340 lines of real content changes (new root-level Module<T>, IModuleContext, IPipelineContext, ModuleResult<T>, ModuleConfigurationBuilder, None, the touched source generators, DI setup, ModuleRunner/ModuleStateTracker/DistributedModuleExecutor, and secret-related types), and grepped the tree for stale fully-qualified-name string literals used by generators/analyzers for symbol matching. The rename itself is clean and consistent. Two concrete bugs remain, both in the Roslyn analyzer/code-fix project, where a namespace string-replace pass over embedded source-code literals was applied too broadly/narrowly:
1. Test fixture references a namespace that no longer matches its own declaration (blocking)
src/ModularPipelines.Analyzers/ModularPipelines.Analyzers.Test/ModularPipelinesAnalyzersUnitTests.cs:20-45
GeneratedAccessorSource still declares Module1 inside namespace ModularPipelines.Examples.Modules, but the generated extension methods in the same embedded string now reference it as ModularPipelines.Examples.ModularPipelines.Module1 — a type path that doesn't exist. This fixture is compiled inside VerifyCS.VerifyAnalyzerAsync(GeneratedAccessorSource, ...), so it will fail with CS0234/CS0246 rather than exercising the analyzer as intended.
CodeRabbit already flagged this exact spot in a prior review comment ("Update GetModule1Module and GetModule1ModuleIfRegistered to reference ModularPipelines.Examples.Modules.Module1"), but it's still present at the current head (e755ce4), so it hasn't been addressed yet.
Suggestion: fix the two FQN references back to ModularPipelines.Examples.Modules.Module1. Longer term, embedding source as raw C# string literals is exactly what makes this class of bug easy to introduce during a mechanical rename — a search-and-replace can't distinguish "namespace segment" from "arbitrary substring." Where feasible, prefer referencing shared fixture snippets by nameof/constants for the namespace/type parts, or add a compile-check test that actually compiles the fixture strings (not just runs the analyzer against them) so a mismatch fails loudly instead of only manifesting as an obscure diagnostic-count mismatch.
2. Code-fix inserts a using that no longer contains the attribute it's fixing (blocking)
src/ModularPipelines.Analyzers/ModularPipelines.Analyzers.CodeFixes/Extensions/SyntaxNodeExtensions.cs:13
AddUsings() still adds using ModularPipelines.Attributes; to support the generated [DependsOn<T>] attribute. This PR moved DependsOnAttribute out of ModularPipelines.Attributes into the root ModularPipelines namespace (src/ModularPipelines/DependsOnAttribute.cs:4) — and ModularPipelines.Attributes still exists as a real namespace (many other attributes live there), so this isn't a dangling using that the compiler would flag; it silently fails to bring DependsOnAttribute into scope. Any consumer applying MissingDependsOnAttributeCodeFixProvider without the package's implicit global using ModularPipelines; (older SDK, ImplicitUsings disabled, or the code fix exercised in isolation/tests) ends up with code that still doesn't compile (CS0246) after "fixing" the diagnostic — the code fix's entire purpose is defeated.
Suggestion: change the hardcoded string in AddUsings() to "ModularPipelines" to match the attribute's new home. More robust: since this generator/analyzer pair is presumably reading the actual DependsOnAttribute symbol to build the diagnostic in the first place, derive the using from that symbol's ContainingNamespace rather than hardcoding the namespace as a string — that removes this whole class of drift the next time the attribute moves.
Non-blocking observation
The new buildTransitive/ModularPipelines.props adds an implicit global using ModularPipelines; to every consuming project, and the root namespace now holds very generic identifiers (None, Module, IsCI, IsLocal, OnWindows, etc.). RELEASE_NOTES_V4.md calls this out as an intentional breaking change, so I'm not raising it as a finding, but it's worth being aware it can produce CS0104 ambiguous-reference errors for any consumer whose own code or other dependencies already export a same-named type (e.g. option/functional libraries exporting None).

Addressed the remaining blocking review findings in 02f1d61: the analyzer fixture now references ModularPipelines.Examples.Modules.Module1, and the code fix inserts using ModularPipelines for DependsOn. Also completed the namespace fixture migration and extracted the three CodeFactor complexity hotspots without behavior changes. Validation: analyzer suite 505/505 passed; OptionsGenerator suite 1232/1232 passed; focused ModuleResult JSON contracts 22/22 passed; CodeFactor is green. |

Review: Reorganize public namespaces for v4
This is a very large (3800+ file) but almost entirely mechanical namespace-reorganization refactor. I verified a broad, representative sample across the core engine, source generators, options generator, test suite (including the largest/most-suspicious test diffs and the new NamespaceOrganizationTests.cs API-surface lock-in test), and found the refactor internally consistent and correctly propagated in nearly every case — no weakened assertions, no deleted test coverage, no logic changes hidden in the mechanical diff noise.
Three minor issues survived verification:
1. Generated-file header comment pushed off line 1 (src/ModularPipelines.AmazonWebServices/Services/Aws.cs:1)
A new using ModularPipelines.Context; was inserted before the // <auto-generated> header comment, so the comment is no longer the first content in the file. Roslyn's generated-code heuristic (used by analyzers, StyleCop, dotnet format, and coverage tooling) detects generated files by checking that the <auto-generated> marker is in the leading trivia of the file's very first token. This file has no *.Generated.cs filename pattern and no [GeneratedCode]/[ExcludeFromCodeCoverage] attribute to fall back on, so it relied solely on being first. With this repo's TreatWarningsAsErrors=true, this could surface new analyzer diagnostics on the file or make dotnet format --verify-no-changes want to reformat it. This is the only file in the entire diff where this ordering regression occurs — looks like a one-off slip in whatever bulk-fixup tooling added the missing using. Suggest moving the using below the header comment.
2. Redundant self-referencing using directives
src/ModularPipelines/Context/ModuleContext.cs, ModuleHookContext.cs, and PipelineContext.cs each gained a using ModularPipelines.Context; despite already being declared inside namespace ModularPipelines.Context;. Not a build break, but dead code left behind by the bulk fixup that would trip IDE0005 if code-style enforcement is ever turned on, and could mislead a reader into thinking a same-namespace type comes from elsewhere. Worth stripping these three.
3. Duplicated ReadState helper in ModuleResult.cs (~line 649)
The JSON-read-state extraction introduced two near-identical private ReadState classes — one in ModuleResultNonGenericJsonConverter, one in ModuleResultJsonConverter<T> — duplicating the same fields (Discriminator, ModuleName, ModuleTypeName, ModuleDuration, ModuleStart, ModuleEnd, ModuleStatus, Exception, SkipDecision), differing only by the generic converter's extra ValueTypeName/ValueElement. Not a correctness bug — the refactor preserves original defaults/control flow — but it's a maintenance trap: a future property added to ModuleResult metadata needs updating in both classes' fields and both ReadProperty switches, and missing one would silently desync generic vs. non-generic deserialization. A shared base type (or record) for the common fields, with the generic converter's state deriving from it, would remove the duplication and make future additions single-point-of-change.
None of these block the mechanical correctness of the refactor, but they're easy fixes worth cleaning up before merge.

Fixed the cross-solution namespace compile failures in a8316cf. Removed the invalid analyzer-test project import, migrated its root Module/CommandResult/SecretValue fixtures, updated ModuleExtensionsGenerator output and snapshot to use the root namespace, and synced the stale generated Pulumi secret import with current generator behavior. Validation: Pulumi solution Release build passed (0 warnings/errors); Development.Analyzers tests 30/30 passed; ModuleExtensionsGenerator tests 7/7 passed. |

Review update — head a8316cf132
This PR has already been reviewed twice by Claude at earlier heads (e755ec4, 02f1d61b). Since the last review, one follow-up commit landed: a8316cf132 — "fix(api): finish namespace consumers", a small 6-file/10-line diff.
Verified: both prior blocking findings are now fixed
- The analyzer test fixture (
ModularPipelinesAnalyzersUnitTests.cs) now correctly referencesModularPipelines.Examples.Modules.Module1in both the source and the generated-accessor comparison string — the CS0246-causing mismatch is resolved. SyntaxNodeExtensions.AddUsings()now insertsusing ModularPipelines;(notModularPipelines.Attributes), matchingDependsOnAttribute's new root namespace — the code fix no longer silently produces non-compiling output.
Verified: this commit's own changes are correct
ModuleExtensionsGenerator.cscollapsed threeusingdirectives (Context,Models,Modules) intousing ModularPipelines;. ConfirmedIModuleContext,ModuleResult<T>, andIModuleContext.GetModule<TModule>()all now live in the rootModularPipelinesnamespace, so the generated extension file still compiles with the single using. Test fixtures and the verified snapshot (ModuleExtensionsGenerator.BuildModule.verified.txt) were updated consistently.- The added
using ModularPipelines.Secrets;inPulumiEnvProviderAzureLoginStaticOptions.Generated.csis needed for the[SecretValue]attribute onClientSecretand matches what the options generator's own test suite (GeneratorHardeningTests.cs,GlobalOptionsBaseGeneratorTests.cs) already asserts it emits — this looks like a stale generated file getting back in sync with the generator, not a hand-edit that fights it. IncrementalGeneratorCachingTests.csandVirtualCommandAnalyzerTests.csfixture namespaces were updated in lockstep with the same root-namespace move, keeping the caching/analyzer test infrastructure consistent with the real API shape.
Not yet addressed (carried over from the previous review, still present at this head)
These were flagged as non-blocking cleanup in the prior review and are still outstanding — repeating so they aren't lost given the PR's size:
src/ModularPipelines.AmazonWebServices/Services/Aws.cs:1— theusing ModularPipelines.Context;is still ahead of the// <auto-generated>header comment, which can defeat Roslyn's "generated file" detection (based solely on the marker being the first token) for the one file in the diff where this happened.src/ModularPipelines/Context/ModuleContext.cs,ModuleHookContext.cs,PipelineContext.cs— each still has a redundantusing ModularPipelines.Context;despite being declared insidenamespace ModularPipelines.Context;.src/ModularPipelines/ModuleResult.cs(ReadStatehelper) — the two near-identical privateReadStateclasses for the generic/non-generic JSON converters are still duplicated rather than sharing a common base for the overlapping fields.
None of these are correctness-blocking on their own, but since the instructions here treat any outstanding actionable item as blocking the verdict, they're called out again rather than silently dropped now that a new commit has landed.

Code review
This is a very large, mostly mechanical PR (3,883 files changed) that moves module-authoring types into the root ModularPipelines namespace and reorganizes contexts/hooks/secrets/reporting into feature namespaces, plus a build-transitive global using. Automated size-limited reviewers (Greptile, CodeRabbit) couldn't fully process this diff, so I focused on:
- Every file whose diff wasn't a pure
Enums.X→X/Attributes.DependsOn<T>→DependsOn<T>rename (identified the ~50 non-trivial files viagit diff --numstat, after filtering out the ~3,800 files that are single-line namespace-only renames or regeneratedPublicAPI.Unshipped.txt/*.Generated.csentries). - The hand-written logic changes:
ModuleResult.cs's JSON-converter refactor,OptionsClassGenerator.cs's newusing ModularPipelines.Secrets;emission (spot-checked several of the ~600 regeneratedOptions/*.Generated.csfiles to confirm they match),ModuleMetadataGenerator.cs/ModuleExtensionsGenerator.cs's namespace-matcher constants, the newNamespaceOrganizationTests.cs, and thePublicAPI.Shipped.txt/Unshipped.txtbookkeeping. - Whether the two P1 findings from the earlier Codex review (on commit
741309d) were addressed at the current head.
Findings:
- Confirmed both earlier Codex P1 findings are fixed at head
c034039:ModuleMetadataGenerator's module-namespace matcher and the source generator's generic[DependsOn<T>]recognition now point at the rootModularPipelinesnamespace instead ofModularPipelines.Modules/ModularPipelines.Attributes, so relocated modules/attributes get the trim/AOT-safe generated registration path again instead of falling back to reflection. ModuleResult.cs's move + refactor (deduplicating the generic/non-generic JSON converter property-reading loops into sharedModuleResultReadState/ModuleResultValueReadStateclasses) preserves the original branch logic exactly while removing real duplication — good opportunistic cleanup riding along with the namespace move.PublicAPI.Shipped.txtloses ~900 lines whilePublicAPI.Unshipped.txtgains matching*REMOVED*markers plus new root-namespace entries — traced a sample (DependsOnAttributeand friends) end to end and the bookkeeping is internally consistent with the Roslyn PublicAPI analyzer's contract. One process note for consideration rather than a bug: the more conventional approach is to leavePublicAPI.Shipped.txtuntouched until v4 actually ships and letPublicAPI.Unshipped.txtalone carry the removed/added bookkeeping in the meantime — that keeps an accurate historical record of what's actually live on NuGet today (v3.2.1239) if anyone needs to diff against it before release. Given how much back-and-forth this file already caused across the PR's history, you may have already weighed this tradeoff deliberately.- New
test/ModularPipelines.UnitTests/Api/NamespaceOrganizationTests.csaccurately asserts the new namespace locations against the actual moved types and that the old locations are gone — a solid regression guard for exactly the kind of migration this PR performs.
No blocking issues found. Given the scale of this diff I couldn't hand-verify all ~3,800 files individually, but every file I sampled follows a highly consistent, mechanical pattern, and the generated-file regenerations are internally consistent with their generator's source changes. I'd treat the still-pending CI jobs (analyzers, build (windows-latest), build (macos-latest), pipeline (ubuntu-latest), trim and Native AOT) as the real gate at this scale rather than manual review alone.
