Keep shipped public API entries when recording removals

[thomhurst]

Public API synchronization retains shipped declarations while recording their removal, restores shipped history from orphaned removal markers, and removes stale markers when an API is reintroduced. CI rejects orphaned markers, markers in shipped files, and duplicate entries. Release-time collapse of shipped/removal pairs remains tracked by #3997.

The shared parser now owns blank/header/entry classification as well as the removal prefix. Merge, history repair, validation, and summaries use the same rules. API line text remains exact, matching the pinned analyzer's removal recognition and payload comparison; leading or trailing whitespace is not normalized into a different API. Negative validator tests capture each child process's exit code while preserving the caller's previous code.

This branch is rebased onto main at b9e1a0f. The previous Ubuntu failure was the command-ordering test waiting for a file logger to contain completion output. That test now records logger calls directly, retains its ordering assertions, requires successful command execution, and disposes the pipeline in a finally block.

Validation at e2bc359:

• Baseline validator passes for all 61 package projects.
• Six PowerShell suites pass: shared line/marker parsing, baseline validation, merge/reintroduction/idempotency, history repair, API summary, and synchronization orchestration.
• Regressions reproduced inconsistent handling of an indented header and leaking native exit-code state before the fixes. Existing exact-marker tests remain intact.
• Release core/test solution builds with 181 warnings and zero errors; all 52 command logger tests pass.
• Scoped formatting and git diff --check pass. The formatter reports its existing unsupported F# fixture project.
• All local dotnet validation retains the default 10-minute/2-GB guard.

Earlier authoritative jq children were incorporated, but this rebase and parser update change generator inputs. Final jq generation succeeded at https://github.com/thomhurst/ModularPipelines/actions/runs/34797964854 and its provenance-only refresh was incorporated through #4913 after all 11 checks passed and reviews cleared it. Current parent head: 0f06c40. Fresh parent CI and review are required before merge. No generated baseline or provenance was hand-edited.

Closes #4638

Review: Keep shipped public API entries when recording removals

This PR reworks the public-API baseline lifecycle so shipped entries are preserved and *REMOVED* markers are only written/kept when there's a matching shipped declaration, plus a one-time migration that purges ~19,600 orphaned markers across all tool packages. I traced the core scripts (Merge-PublicApiBaselineSnapshot.ps1, Assert-PublicApiBaselines.ps1, Write-PublicApiChangeSummary.ps1) against their updated test suites and spot-checked the migrated data — the algorithm is sound and well covered by tests.

Two smaller issues survived verification:

1. Duplicate marker left in the migrated baseline
src/ModularPipelines/PublicAPI.Unshipped.txt:20 and :32 are an exact duplicate line:

*REMOVED*ModularPipelines.Distributed.IDistributedCoordinator.DequeueModuleAsync(System.Collections.Generic.IReadOnlySet<string!>! workerCapabilities, System.Threading.CancellationToken cancellationToken) -> System.Threading.Tasks.Task<ModularPipelines.Distributed.ModuleAssignment?>!

The migration's stated goal was to make these baseline files internally consistent, but it left this adjacent duplicate in the very file it rewrote. Worth deduplicating now (e.g. via Sort-Object -Unique) rather than leaving it for a future Sync run's HashSet to quietly clean up — an unnecessary diff/noise source in the meantime.

2. *REMOVED* prefix/parsing logic duplicated across three scripts
$removedPrefix = '*REMOVED*' plus the .Substring($removedPrefix.Length) stripping logic is independently reimplemented in:

• scripts/Assert-PublicApiBaselines.ps1 (new orphan check)
• tools/ModularPipelines.OptionsGenerator/scripts/Merge-PublicApiBaselineSnapshot.ps1
• tools/ModularPipelines.OptionsGenerator/scripts/Write-PublicApiChangeSummary.ps1

If the marker convention ever changes (different prefix, different trim rule), an editor who updates one copy and misses the other two would silently reintroduce the exact orphaned-marker bug this PR fixes. Consider factoring this into a small shared .ps1 helper (dot-sourced or a module) that all three scripts import, so the convention has one source of truth.

Neither issue blocks the core fix, but both are worth addressing before merge given the PR's own goal is baseline consistency and preventing marker drift.

Review: Keep shipped public API entries when recording removals

Re-reviewed at HEAD 4e68dca. This PR reworks the public-API baseline lifecycle so shipped entries are preserved and *REMOVED* markers are only written/kept when a matching shipped declaration exists, plus a one-time migration purging orphaned markers. The core algorithm in Merge-PublicApiBaselineSnapshot.ps1, Assert-PublicApiBaselines.ps1, and Write-PublicApiChangeSummary.ps1 is sound and matches the test fixtures.

Both issues raised in the previous review are still present and unaddressed at this HEAD:

1. Duplicate marker still in the migrated baseline
src/ModularPipelines/PublicAPI.Unshipped.txt:20 and :32 remain an exact duplicate:

*REMOVED*ModularPipelines.Distributed.IDistributedCoordinator.DequeueModuleAsync(System.Collections.Generic.IReadOnlySet<string!>! workerCapabilities, System.Threading.CancellationToken cancellationToken) -> System.Threading.Tasks.Task<ModularPipelines.Distributed.ModuleAssignment?>!

Since this PR's own goal is baseline consistency (and it added an orphan-marker check specifically to catch drift like this), leaving a duplicate in the very file the migration rewrote undercuts that goal. Worth deduplicating now (e.g. Sort-Object -Unique in the migration script) rather than relying on a future Sync run's HashSet to silently absorb it.

2. *REMOVED* prefix/parsing logic still duplicated across three scripts
$removedPrefix = '*REMOVED*' plus the .StartsWith(...) / .Substring($removedPrefix.Length) convention is still independently implemented in:

• scripts/Assert-PublicApiBaselines.ps1 (lines 47, 52, 63)
• tools/ModularPipelines.OptionsGenerator/scripts/Merge-PublicApiBaselineSnapshot.ps1 (lines 12, 62, 82, 88, 92)
• tools/ModularPipelines.OptionsGenerator/scripts/Write-PublicApiChangeSummary.ps1 (lines 29, 43-44)

This is the exact kind of triplication that lets marker-convention drift reintroduce the orphaned-marker bug this PR fixes — an editor changing the prefix or trim rule in one script and missing the other two would silently break the invariant again. A small shared .ps1 helper (dot-sourced, or a .psm1 module imported by all three) exposing something like Get-RemovedMarkerPrefix, Test-RemovedMarker, and Get-RemovedMarkerEntry would make the convention single-sourced and put future changes in one place instead of three.

Minor (new, non-blocking): scripts/Assert-PublicApiBaselines.ps1 re-derives $projectDirectory (and effectively $unshippedPath) in the orphan-detection loop (line 49-50) that the preceding missing-baseline loop (line 29) already computed. Not a correctness issue — the missing-baseline throw guarantees the files exist by the time the second loop runs — but folding both checks into a single pass over $packageProjects would avoid the duplicated path-building work and keep future per-project checks in one place.

Neither of the two carried-over issues blocks correctness of the core fix, but both were called out as pre-merge items given the PR's stated goal of eliminating baseline drift, and neither has been addressed since.

[thomhurst]

Addressed both carried-over findings at exact head a68ce8d.

1. *REMOVED* convention triplicated. Added scripts/PublicApiRemovedMarker.ps1 exposing Get-RemovedMarkerPrefix, Test-RemovedMarker, Get-RemovedMarkerEntry and New-RemovedMarker, and dot-sourced it from Assert-PublicApiBaselines.ps1, Merge-PublicApiBaselineSnapshot.ps1 and Write-PublicApiChangeSummary.ps1. None of the three defines the prefix or its parse rule any more. The helper is covered by scripts/Test-PublicApiRemovedMarker.ps1 (prefix, round-trip, ordinal/no-trim rejection cases, guard on non-markers).

2. Duplicated per-project path derivation in the assert script. The missing-baseline and orphaned-marker checks are now one pass over $packageProjects: each project derives its two baseline paths once, a project with a missing file is recorded and skipped, and the throw order (missing first, then orphans) is unchanged so the existing test still discriminates both failures.

Also wired Test-PublicApiRemovedMarker.ps1 and the pre-existing Test-AssertPublicApiBaselines.ps1 (which CI never ran) into dotnet.yml ahead of the baseline coverage step.

Local runs: the five script tests (Test-PublicApiRemovedMarker, Test-AssertPublicApiBaselines, Test-MergePublicApiBaselineSnapshot, Test-SyncPublicApiBaselines, Test-WritePublicApiChangeSummary) all pass, and Assert-PublicApiBaselines.ps1 verifies 61 package projects on this head.

Correction and resync at exact head 42a24ec49e. My earlier resync to 8fc873a441 was made from a stale local branch and dropped the a68ce8d20a refactor (shared scripts/PublicApiRemovedMarker.ps1 helper, single-pass assert script, CI wiring for the two script tests). That commit is restored: the branch is now fix(publicapi) + refactor(publicapi) rebased onto current main (Argo CD baseline re-migrated after #4535), plus one more commit that adds scripts/PublicApiRemovedMarker.ps1 to Get-GeneratedOptionsSourcePath and the Generate CLI Options push paths, as the Codex thread asked. Local: all six baseline/marker/provenance script tests pass and Assert-PublicApiBaselines.ps1 verifies 61 packages. @claude please re-review exact head 42a24ec.

Review: Keep shipped public API entries when recording removals

Re-reviewed at HEAD 42a24ec. The core algorithm change is sound: Merge-PublicApiBaselineSnapshot.ps1 now keeps every original shipped entry, only adds a *REMOVED* marker when RS0017 has actually confirmed the removal, and only carries an existing marker forward while its entry is still shipped and still absent from the current snapshot — so it can no longer produce an orphan, and it correctly drops a marker if the API reappears. Write-PublicApiChangeSummary.ps1 and Assert-PublicApiBaselines.ps1 treat the marker consistently with that model.

Both issues raised in the earlier automated review rounds on this thread are now handled:

• Marker convention triplication — fixed. scripts/PublicApiRemovedMarker.ps1 is the single source for the *REMOVED* prefix and its parse rule, dot-sourced from Assert-PublicApiBaselines.ps1, Merge-PublicApiBaselineSnapshot.ps1, and Write-PublicApiChangeSummary.ps1, with its own test file. It's also wired into GeneratedOptionsProvenance.ps1 and generate-cli-options.yml so the Generate CLI Options job re-triggers when it changes.
• Duplicated per-project path derivation in the assert script — fixed, now a single pass building both baseline paths per project.
• CI wiring for Test-PublicApiRemovedMarker.ps1 and Test-AssertPublicApiBaselines.ps1 was added to dotnet.yml ahead of Assert-PublicApiBaselines.ps1 — confirmed present at lines 105–112.

One finding from the first two review rounds is still unresolved and looks build-breaking, not cosmetic.

src/ModularPipelines/PublicAPI.Unshipped.txt lines 20 and 32 are still an exact duplicate line at this HEAD:

*REMOVED*ModularPipelines.Distributed.IDistributedCoordinator.DequeueModuleAsync(System.Collections.Generic.IReadOnlySet<string!>! workerCapabilities, System.Threading.CancellationToken cancellationToken) -> System.Threading.Tasks.Task<ModularPipelines.Distributed.ModuleAssignment?>!

This was flagged twice before as a leftover from the one-time migration. Looking back at the thread, the author's "addressed both carried-over findings" reply actually fixed a different pairing (marker triplication + assert-script path duplication) — the duplicate-line finding itself was never touched, and it's still there verbatim.

This isn't just noise to clean up later: Directory.Build.props sets TreatWarningsAsErrors=true for CI builds (line 23) and, specifically for the ModularPipelines project, force-enables RunAnalyzers/RunAnalyzersDuringBuild in CI (lines 48–52) with Microsoft.CodeAnalysis.PublicApiAnalyzers referenced (line 45). Only RS0026/RS0041/a handful of MPG* rules are pulled out of "as error" treatment for that project (line 54, 56) — RS0024 ("the contents of the public API files are invalid"), which is the diagnostic PublicApiAnalyzers raises for a duplicate entry within the same file, is not excluded. ModularPipelines.slnx (which contains this project) is built directly in dotnet.yml (e.g. lines 298, 676). I wasn't able to actually execute a build in this review sandbox to get the compiler's diagnostic text (the run required interactive approval that isn't available here), so please verify with a real build before merging, but the config alone points to this duplicate turning into a hard CI failure on the exact project this PR is trying to fix.

Suggested fix: route the one-time migration output through the same dedupe path Merge-PublicApiBaselineSnapshot.ps1 already uses (HashSet + Sort-Object/[Array]::Sort) instead of hand-editing/concatenating lines, so a duplicate like this can't survive the migration silently. A couple of other migrated files (ModularPipelines.GitHub, ModularPipelines.DotNet) were spot-checked and came back clean, so this looks isolated to this one file rather than systemic — but worth a sort | uniq -d sweep across all 54 touched PublicAPI.Unshipped.txt files before merging to be sure.

[thomhurst]

Addressed the remaining finding at exact head beb88f6e8e (rebased onto current main after #4462, conflict-free). The duplicated *REMOVED*...DequeueModuleAsync line in src/ModularPipelines/PublicAPI.Unshipped.txt predates this PR (it is present on main too), so the migration did not create it; it is now removed, and a sort | uniq -d sweep across every PublicAPI.*.txt finds no other repeats. To keep that true, Assert-PublicApiBaselines.ps1 now also fails on any entry listed twice in a baseline (bulk set-count fast path, per-line report only on mismatch; the tree check still runs in ~2.6 s for 61 packages), with a case in Test-AssertPublicApiBaselines.ps1. All six script tests pass locally. @claude please re-review exact head beb88f6.

Code review

Reviewed the shift to a PublicApiAnalyzers-lifecycle-aligned baseline sync (retain shipped entries, retire via REMOVED markers, only collapse on a future release "ship" step) plus the one-time migration that drops orphaned markers.

Findings: none blocking.

What I checked:

• Merge-PublicApiBaselineSnapshot.ps1: shipped entries are now never dropped, and a REMOVED marker is only carried forward while its entry is still shipped and still absent from the current snapshot, so a marker can never be written or retained without a corresponding shipped line. This matches the PR description and eliminates the root cause (orphaned markers written same-commit as the shipped-line deletion).
• scripts/PublicApiRemovedMarker.ps1 (new): small, well-scoped shared helper (prefix, test/get/new) that both the merge script and the new Assert-PublicApiBaselines.ps1 orphan check dot-source, avoiding duplicating the marker-prefix string across files.
• scripts/Assert-PublicApiBaselines.ps1: new orphan-marker and duplicate-entry fast-fail checks are correct and reasonably efficient (duplicate check short-circuits via a HashSet count comparison before doing a line-by-line walk on 100k+ line shipped baselines).
• Write-PublicApiChangeSummary.ps1: consistently treats a marker as retiring its shipped entry on both the "old" and "current" snapshot sides, so added/removed/signature-changed counts stay correct under the new shape.
• Test coverage is thorough: Test-MergePublicApiBaselineSnapshot.ps1 adds an explicit "no confirmed removals" case (shipped untouched, no marker), keeps the removal/signature-change/idempotency cases, and drops the old case that fed an orphaned marker in. Test-AssertPublicApiBaselines.ps1 adds orphan and duplicate-entry failure cases. Test-PublicApiRemovedMarker.ps1 covers the marker helper edge cases (indentation, casing, empty, round-trip).
• CI wiring (dotnet.yml, generate-cli-options.yml) correctly adds the new test scripts to the pipeline and adds PublicApiRemovedMarker.ps1 to the regen-trigger fingerprint list.
• Spot-checked the one-time migration across several of the 54 rewritten PublicAPI.Unshipped.txt files (Docker, Terraform, Helm, AmazonWebServices, GitHub, Testing, Cmd, core ModularPipelines): in every file sampled, the only lines removed were REMOVED markers, and each removed marker had no corresponding entry left in PublicAPI.Shipped.txt, i.e. they were genuinely inert orphans rather than markers this PRs own logic would have kept. The ~92 markers retained in ModularPipelines and ModularPipelines.GitHub do still have live shipped entries.

Nothing here rises to a blocking issue: the design closes the exact bug described in #4638, the writer/reader logic is symmetric and covered by new tests, and the bulk migration matches what the new invariant would produce.

[thomhurst]

Addressed both CodeRabbit findings at exact head 58fc729885: markers now compare exactly against shipped entries (no trimming, matching the merge script), and a plain symbol present in both baselines is reported as an RS0025 duplicate while the shipped-entry-plus-marker pair remains valid. Both files are read once per project. Test-AssertPublicApiBaselines.ps1 covers both cases; the tree check still passes for 61 packages in ~3.5 s. @claude please re-review exact head 58fc729.

Code review

Re-reviewed at HEAD 58fc729, the exact commit requested in the last author reply. I traced the full lifecycle change independently (not just diffed against the prior automated reviews on this thread) across Merge-PublicApiBaselineSnapshot.ps1, Assert-PublicApiBaselines.ps1, Write-PublicApiChangeSummary.ps1, PublicApiRemovedMarker.ps1, and their test files, plus spot-checked several of the 54 migrated PublicAPI.Unshipped.txt files.

Findings: none blocking.

What I verified:

• Core invariant holds and can't regress silently. Merge-PublicApiBaselineSnapshot.ps1 now keeps every original shipped entry unconditionally, only adds a *REMOVED* marker when the RS0017 confirmed-removal gate says so, and only carries an existing marker forward while its target is both still shipped and still absent from the current snapshot. By construction the writer can't produce an orphan, and reintroducing a removed API correctly drops its marker on the next sync. Test-MergePublicApiBaselineSnapshot.ps1's idempotency + "no confirmed removals" + orphan-dropping (Api.Historical) cases confirm this by direct execution trace, not just by reading the assertions.
• Both previously-flagged CodeRabbit findings on this exact head are actually fixed, not just claimed fixed. I read Assert-PublicApiBaselines.ps1 directly: line 84 compares $shipped.Contains((Get-RemovedMarkerEntry $line)) with no Trim(), matching the merge script's exact-match semantics (confirmed by the new trailing-whitespace-marker test case in Test-AssertPublicApiBaselines.ps1). Line 88's elseif ($shipped.Contains($line)) branch now catches a plain entry duplicated across both baseline files (the RS0025 shape) while still treating a shipped-entry-plus-its-marker pair as valid — also covered by a new test case (Api.Kept ... (also in PublicAPI.Shipped.txt)).
• Single source of truth for the marker convention. scripts/PublicApiRemovedMarker.ps1 is dot-sourced by all three consumers; no script re-implements the *REMOVED* prefix or parsing rule anymore. It's wired into GeneratedOptionsProvenance.ps1/generate-cli-options.yml so the regen job re-triggers on changes to it, and it has its own edge-case test file.
• Change-summary generation stays correct under the new shape. Write-PublicApiChangeSummary.ps1's Read-ActiveApi now nets out *REMOVED* markers against entries via ExceptWith on both the "old" and "current" snapshot sides, so added/removed/signature-change counts remain accurate for the generated PR body. Verified against Test-WritePublicApiChangeSummary.ps1's updated fixture (shipped entry retained, matching marker added, added/removed counts updated).
• CI wiring is in place, not just added and forgotten: Test-PublicApiRemovedMarker.ps1 and Test-AssertPublicApiBaselines.ps1 (previously never run in CI) are now invoked in dotnet.yml ahead of Assert-PublicApiBaselines.ps1.
• Migration spot-check. Sampled several of the 54 rewritten PublicAPI.Unshipped.txt files (Docker, AmazonWebServices, Ansible, core ModularPipelines) — every removed line in the diff is a *REMOVED* marker whose shipped counterpart is already gone, i.e. a genuine dead orphan under the new invariant, not something the new logic would have kept.

This closes out a long review thread (orphan-marker root cause → triplicated convention → leftover duplicate line → trim/duplicate-detection edge cases) where each round's finding was actually addressed rather than deferred, and the fix now matches its own stated goal: shipped entries are never dropped, and a marker without a shipped entry can no longer exist.

[thomhurst]

Fixed the Fast fail failure at exact head 5dac5398f4 (also rebased onto current main after #4656, conflict-free). Test-AssertPublicApiBaselines.ps1 matched the assert script's message against the console-rendered output, which PowerShell wraps at 80 columns with a gutter on Linux, so the long cross-file-duplicate message never matched there. The two long-message cases now run the script in-process and inspect the thrown message. No product change; all script tests and the 61-package tree check pass locally.

Review: Keep shipped public API entries when recording removals

Both issues from my previous review pass have been addressed:

1. Duplicate marker in migrated baseline — the duplicate *REMOVED*...DequeueModuleAsync(IReadOnlySet<string!>...) line in src/ModularPipelines/PublicAPI.Unshipped.txt is gone; only one occurrence remains now.
2. Duplicated *REMOVED* prefix/parsing logic — now consolidated into scripts/PublicApiRemovedMarker.ps1 (Get-RemovedMarkerPrefix, Test-RemovedMarker, Get-RemovedMarkerEntry, New-RemovedMarker), dot-sourced by Assert-PublicApiBaselines.ps1, Merge-PublicApiBaselineSnapshot.ps1, and Write-PublicApiChangeSummary.ps1, with its own test coverage in Test-PublicApiRemovedMarker.ps1. This is exactly the right fix — one source of truth for the marker convention.

I re-traced the core algorithm (shipped entries are retained, a marker is only written/kept while its entry is both still shipped and still absent from the current snapshot) against the updated test suites and the previously-flagged migration data, and it holds up.

One small, low-severity inconsistency remains:

Blank-line handling differs between the merge script and the new CI gate

• tools/ModularPipelines.OptionsGenerator/scripts/Merge-PublicApiBaselineSnapshot.ps1's Read-Baseline drops any line matching [string]::IsNullOrWhiteSpace($_) (treats whitespace-only lines as blank).
• scripts/Assert-PublicApiBaselines.ps1's Test-ApiEntry only checks $Line.Length -gt 0, so a whitespace-only line (e.g. a single trailing space introduced by a manual merge-conflict resolution touching these baseline files) is treated as a real API entry.

Since Assert-PublicApiBaselines.ps1 is the fast-fail CI gate and runs before the next merge/sync pass, this divergence means a stray whitespace line could trip a spurious duplicate/orphan failure in CI that the merge script itself would have silently ignored. It's a narrow edge case (these files are normally machine-written), but since the whole point of this PR is closing baseline-consistency gaps between the tools that read/write these files, it'd be worth having Test-ApiEntry use the same IsNullOrWhiteSpace check as Read-Baseline for consistency — possibly by moving both blank/comment-line filtering rules into the same shared PublicApiRemovedMarker.ps1-style helper that now houses the marker convention, so all three scripts agree on what counts as a real baseline entry, not just what counts as a marker.

Not blocking, but worth a quick follow-up.

[thomhurst]

CI on 5dac539 failed in the Test public API baseline checks step after both scripts printed success: the last negative case in Test-AssertPublicApiBaselines.ps1 runs the gate in a child pwsh that is expected to fail, leaving \0 at 1, which the Actions pwsh shell reports as the step's exit code. 89864c6 ends the script with an explicit exit 0 (emulated the wrapper locally: exit 0). It also picks up the review's whitespace observation: Test-ApiEntry now treats whitespace-only lines as blank like Read-Baseline in the merge script, with a test case. Real gate on this checkout: 61 package projects verified.

@claude please re-review exact head 89864c6.

[thomhurst]

Merged main (brew #4621 and pulumi #4637 regenerations conflicted on their PublicAPI.Unshipped.txt). Resolution takes main's regenerated files and applies the PR's one-time migration rule to them: markers whose shipped entry is already gone are dropped, so the new orphan check passes. Assert-PublicApiBaselines.ps1 on the merged tree: 61 package projects verified; the baseline test step exits 0.

@claude please re-review exact head 1449139.

Review: Public API baseline validation - shared REMOVED marker helper

This follow-up commit addresses both issues raised in the previous review:

1. Duplicate marker in the migrated baseline - src/ModularPipelines/PublicAPI.Unshipped.txt now has a single REMOVED...DequeueModuleAsync(...) entry (line 20); the duplicate at the old line 32 is gone.
2. REMOVED convention triplication - the new scripts/PublicApiRemovedMarker.ps1 (Get-RemovedMarkerPrefix/Test-RemovedMarker/Get-RemovedMarkerEntry/New-RemovedMarker) is now dot-sourced by scripts/Assert-PublicApiBaselines.ps1, tools/ModularPipelines.OptionsGenerator/scripts/Merge-PublicApiBaselineSnapshot.ps1, and Write-PublicApiChangeSummary.ps1, and is covered by its own Test-PublicApiRemovedMarker.ps1. This is exactly the single-source-of-truth fix that was requested - good catch on wiring it into GeneratedOptionsProvenance.ps1's watch list too, so the CLI-options regen workflow re-triggers if the helper changes.

Two smaller design issues remain in scripts/Assert-PublicApiBaselines.ps1, worth a follow-up (neither blocks this specific fix, but both reduce the value of the new checker as a diagnostic tool):

1. Sequential if { throw } blocks hide all but the first category of failure

Assert-PublicApiBaselines.ps1:95-108 checks missing baselines, orphaned markers, and duplicate entries as three separate gated throws. If a baseline directory has, say, both an orphaned marker and a duplicate entry at once (a plausible outcome of a bad manual edit or a merge conflict), only the orphaned-marker error is ever reported - the duplicate-entry problem stays invisible until the first issue is fixed and CI reruns. Since all three lists (missingBaselines, orphanedMarkers, duplicateEntries) are already being built independently regardless of which condition trips first, this could report all populated categories in a single combined message instead of stopping at the first one - same detection cost, but a contributor fixing baselines sees every problem in one CI run instead of drip-feeding through re-runs.

2. Overlapping/duplicate error output for one underlying data problem

Add-DuplicateEntries (line 38) flags intra-file duplicates, and the main loop's elseif (shipped.Contains(line)) branch (line 89-91) separately flags any plain (non-marker) unshipped entry that's also in PublicAPI.Shipped.txt. If an entry is both duplicated within PublicAPI.Unshipped.txt and also present in PublicAPI.Shipped.txt, it gets reported once by Add-DuplicateEntries and again by the main loop for every occurrence - 3 overlapping lines in the thrown error for what's really one data problem. Deduplicating the unshipped lines once up front (or having the main loop only inspect distinct entries) before running the cross-file check would avoid the redundant noise and make the failure easier to triage at a glance.

Minor, no action needed: Test-AssertPublicApiBaselines.ps1:119 ends with an unconditional exit 0 to reset LASTEXITCODE after intentionally-failing pwsh -File sub-invocations. It's only safe today because it's the last statement in the last script of the dotnet.yml run block (Test-PublicApiRemovedMarker.ps1 then Test-AssertPublicApiBaselines.ps1) - exit inside a non-dot-sourced script invocation terminates the whole pwsh session, not just the local script scope. If a later commit appends another step to that block (mirroring the existing multi-script chains elsewhere in the repo, e.g. generate-cli-options.yml), it would silently never execute. Setting LASTEXITCODE = 0 after the negative-test invocations instead of calling exit 0 would get the same result without depending on this script always being last.

Code review

Re-reviewed at HEAD 539c346. Since the last CLEAR verdict on this thread (69b2642), the only new commit is 539c346 (chore: Update jq CLI options, #4885). I traced its actual diff rather than relying on the description:

• src/ModularPipelines.Jq/Generated/Jq.Generation.json: only the generatorSourceSha256 changes, reflecting the regenerated generator source.
• src/ModularPipelines.Jq/Services/Jq.Generated.cs: the only code change is adding .ConfigureAwait(false) to the ExecuteCommandLineToolAsync await in ExecuteAsync, matching this repo's convention for library code under src/.
• src/ModularPipelines.Jq/PublicAPI.Shipped.txt / PublicAPI.Unshipped.txt: I verified the final file contents directly (not just the diff, since gh pr diff shows this file going through two hunks that individually look like they cancel out). The end state is self-consistent: ExecuteAsync's return type changed from ModularPipelines.Models.CommandResult to ModularPipelines.CommandResult, so the old signature is correctly *REMOVED*-marked in Unshipped while remaining in Shipped (per this PR's core design — shipped history is retained until a release collapses it, deferred to v4.0.0 release checklist #3997), and the new signature is a fresh, unmarked Unshipped entry awaiting release. No orphaned marker, no regression.

This is a minimal, correctly-scoped regen commit and doesn't reintroduce any of the issues raised earlier in this thread (marker-convention triplication, leftover duplicate marker, blank-line/whitespace handling, single-throw error hiding, exit-code fragility) — all of those were confirmed fixed as of 69b2642 and remain fixed here. I did not find any new issues at this HEAD.

Findings: none blocking.

[thomhurst]

Pushed 305f7d4 after diagnosing the new Fast fail failure in run 34792035048. GitHub's synthetic merge incorporated newer Podman baselines from main; 23 new removed entries consequently lacked their shipped declarations. I condensed the already-reviewed fix sequence, rebased its exact final tree onto current main, and reran Repair-PublicApiBaselineHistory.ps1 for Podman. The incremental repair adds 23 shipped declarations and changes no active APIs.

The repository validator now passes for all 61 package projects. An independent comparison against main confirms unchanged active APIs and all 23,469 unique removal records, with 23,290 restored shipped declarations. Four relevant PowerShell suites pass; Podman Release build has zero warnings/errors and all three integration tests pass.

The jq output from #4885 passed its full validation before incorporation, but this rebase changes generator inputs. Fresh authoritative jq generation is queued at https://github.com/thomhurst/ModularPipelines/actions/runs/34792972597 with automatic merging and coverage-shrinkage approval disabled. It must be incorporated and reviewed before merge; no provenance was hand-edited.

Code review

Re-reviewed at HEAD 305f7d4. Since the last CLEAR verdict on this thread (539c346), the author rebased onto current main (which pulled in newer Podman baseline data) and reran Repair-PublicApiBaselineHistory.ps1 for the Podman package to restore 23 shipped declarations that the synthetic merge's newer Podman removals had left orphaned.

I independently verified this round rather than trusting the summary:

• Core scripts unchanged in behavior. scripts/PublicApiRemovedMarker.ps1, scripts/Assert-PublicApiBaselines.ps1, tools/ModularPipelines.OptionsGenerator/scripts/Merge-PublicApiBaselineSnapshot.ps1, and Repair-PublicApiBaselineHistory.ps1 still implement the invariant this whole thread converged on: shipped entries are never dropped, a *REMOVED* marker can only exist while its entry is still shipped and still absent from the current snapshot, and Assert-PublicApiBaselines.ps1 still reports every populated failure category (missing baseline, orphaned marker, duplicate entry) in one combined message rather than stopping at the first. No regression from the rebase.
• Podman baseline invariant holds after the repair. src/ModularPipelines.Podman/PublicAPI.Shipped.txt / PublicAPI.Unshipped.txt have no duplicate lines in either file, and none of the 486 *REMOVED* markers in Unshipped is missing its literal counterpart in Shipped (0 orphans). Spot-checked markers spanning the start, middle, and end of the file (enum member, property getter, several async method signatures) all match exactly.
• CI wiring intact. dotnet.yml still runs Test-PublicApiRemovedMarker.ps1, Test-RepairPublicApiBaselineHistory.ps1, and Test-AssertPublicApiBaselines.ps1 in that order ahead of the Assert-PublicApiBaselines.ps1 coverage step — no merge-conflict artifacts or reordering from the rebase.
• Generator fingerprint intact. Get-GeneratedOptionsSourcePath in GeneratedOptionsProvenance.ps1 still lists scripts/PublicApiRemovedMarker.ps1, so the CLI-options regen job still re-triggers on changes to the marker helper.

Findings: none blocking. The queued fresh jq generation run mentioned in the author's latest comment is explicitly future work (not yet incorporated), not a defect in this head — it will need its own review pass once pushed.

Review

This PR builds on the prior "keep shipped public API entries when recording removals" work by centralizing the *REMOVED* marker convention in scripts/PublicApiRemovedMarker.ps1 and reusing it from Assert-PublicApiBaselines.ps1, Merge-PublicApiBaselineSnapshot.ps1, and Write-PublicApiChangeSummary.ps1. I traced the new marker helper, the merge/history-repair logic, and the CI test wiring against their added tests — the core marker consolidation is correct and well covered. Both issues raised in the previous review round appear addressed: the duplicate DequeueModuleAsync marker in src/ModularPipelines/PublicAPI.Unshipped.txt is gone (only one occurrence remains), and the *REMOVED* prefix/parsing itself now has a single source of truth.

However, that consolidation was only partial, and it introduced a new correctness bug plus a related, unaddressed duplication:

1. Read-ActiveApi trims for the skip-check but not for the marker check (real bug)
tools/ModularPipelines.OptionsGenerator/scripts/Write-PublicApiChangeSummary.ps1:36-47 trims each line into $entry only to test blank/comment (line 38-39), then calls Test-RemovedMarker $line and Get-RemovedMarkerEntry $line (lines 43-44) and adds to $entries (line 46) using the raw, untrimmed $line. Test-RemovedMarker is a strict StartsWith('*REMOVED*', Ordinal) with no trimming of its own. A baseline line with leading whitespace before the marker (e.g. " *REMOVED*Api.Foo" — plausible from a hand-edit or editor auto-indent, since these files are also edited by contributors) fails the marker test, falls into the else branch, and gets added to $entries as a normal active API instead of being netted out. The generated PR change-summary would then report a bogus "added" API while missing the real removal. This is a regression versus the old code, which trimmed before every check.

Fix: use $entry (the already-trimmed value) consistently in the marker test, extraction, and $entries.Add, not the raw $line.

2. The "is this a real baseline entry" predicate is still reimplemented four times, and two of them already disagree
Despite adding PublicApiRemovedMarker.ps1 specifically to keep marker handling in one place, the closely related blank/comment-entry predicate is duplicated across Assert-PublicApiBaselines.ps1's Test-ApiEntry, Merge-PublicApiBaselineSnapshot.ps1's Get-ApiEntries/Get-Headers, Repair-PublicApiBaselineHistory.ps1's inline check, and Write-PublicApiChangeSummary.ps1's Read-ActiveApi. Three of the four test StartsWith('#') on the raw, untrimmed line; Write-PublicApiChangeSummary.ps1 trims first (line 38). A line like " # comment" (leading whitespace before #) is skipped as a comment only in Write-PublicApiChangeSummary.ps1 — the other three would misclassify it as a real API entry. This drift is exactly what produced bug #1 above, and it means any future tweak to the entry convention has to be replicated in four places instead of one.

Since PublicApiRemovedMarker.ps1 already exists as the shared home for this kind of parsing rule, the fix for #1 should go further than a local patch: move the entry predicate (and ideally a shared line-reading helper) into that file so all four scripts consume one implementation, the same way they now share Test-RemovedMarker/Get-RemovedMarkerEntry.

3. $LASTEXITCODE reset in Test-AssertPublicApiBaselines.ps1 is a local patch for a general leak
.github/workflows/dotnet.yml's "Test public API baseline checks" step (lines 108-111) runs Test-PublicApiRemovedMarker.ps1, Test-RepairPublicApiBaselineHistory.ps1, and Test-AssertPublicApiBaselines.ps1 in one continuous pwsh session, so $LASTEXITCODE persists across script boundaries. Test-AssertPublicApiBaselines.ps1 spawns external pwsh -File child processes for its negative test cases that intentionally exit 1, then resets $global:LASTEXITCODE = 0 near the end — but only because it happens to run last in the run: block today. Reordering the three scripts, inserting a new one after it, or adding an external pwsh -File call to either of the other two scripts would silently reintroduce a false CI pass/fail with no test guarding against it. Consider resetting $LASTEXITCODE immediately after each external pwsh -File invocation inside Test-AssertPublicApiBaselines.ps1 (at the call site) rather than once at the end of the file, so the fix doesn't depend on script ordering in the workflow.

None of these block the core marker-consolidation work, which is sound, but #1 is a genuine correctness regression in the generated PR summary and should be fixed before merge; #2 and #3 are the maintenance-risk root causes worth closing out given this PR's own goal of eliminating exactly this kind of drift.

[thomhurst]

Addressed review 5657751611 in e2bc359, with one evidence-based correction to the requested whitespace normalization:

1. Read-ActiveApi must preserve raw API lines. The installed PublicApiAnalyzers 5.6.0 package identifies Roslyn commit c0573ed0a7dc3e3b4d2e70da47f97cc51a35524f in its nuspec. Its ReadApiData implementation uses line.ToString(), skips whitespace-only lines, then tests the removal prefix and retains the remaining payload without trimming. An indented marker is not a removal, and a trailing space changes its payload. Trimming here would invent a retirement the analyzer does not recognize and break the existing exact-marker regression. I removed the inconsistent local trim instead and routed classification through the shared parser. New tests cover indented marker/header lines alongside the existing trailing-space case.
2. Blank/header/entry classification now lives in PublicApiRemovedMarker.ps1. The validator, merge script, history repair, and summary all consume it. Headers retain the existing column-zero convention; all readers now agree about indented lines. The new summary regression failed before this change and passes now.
3. Each negative child process now returns captured output and exit code, with the caller's prior LASTEXITCODE restored in a finally block at the invocation. The end-of-script reset is removed. A regression seeds caller status 23 and verifies it survives the negative check, preventing a later reset from hiding leakage.

The failed Ubuntu artifact from run 34795076606 identified Command_Header_Precedes_Streamed_Output_And_Completion as the sole failed core test. It now observes logger calls directly, keeps every header/output/completion ordering assertion, requires the command to succeed, and always disposes the pipeline. All 52 command logger tests pass. Six PowerShell suites and baseline validation for all 61 packages pass; the Release core/test solution builds with zero errors. Scoped formatting and diff checks pass with the default dotnet guard limits.

Fresh authoritative jq generation is running at https://github.com/thomhurst/ModularPipelines/actions/runs/34797964854 because these script changes affect generator provenance. That output and the new CI/review cycle remain pending before merge.

Code review

Re-reviewed at HEAD e2bc359. Since the last BLOCKING verdict on this thread (90b409e), all three findings from that round are addressed, and I independently verified each against the current code rather than the author's summary:

1. Read-ActiveApi marker/skip mismatch (the real correctness bug) — fixed.
tools/ModularPipelines.OptionsGenerator/scripts/Write-PublicApiChangeSummary.ps1:31-52 now calls Test-PublicApiEntry, Test-RemovedMarker, and Get-RemovedMarkerEntry consistently against the raw, untrimmed $line, and adds the untrimmed line to $entries. The author's justification is correct and evidence-based: ReadApiData in the pinned PublicApiAnalyzers 5.6.0 (per its nuspec-referenced Roslyn commit) does not trim before recognizing the removal prefix or comparing payloads, so trimming here would treat an indented marker as a removal the analyzer doesn't recognize — the opposite of what the original suggestion asked for, and the author explained why they deviated rather than applying it blindly. scripts/Test-PublicApiRemovedMarker.ps1:38-56 and tools/ModularPipelines.OptionsGenerator/scripts/Test-WritePublicApiChangeSummary.ps1:59-88 both cover indented-marker/indented-header and trailing-whitespace cases end to end.

2. Blank/header/entry classification quadruplication — fixed.
scripts/PublicApiRemovedMarker.ps1 now also owns Test-PublicApiHeader/Test-PublicApiEntry, and all four call sites (Assert-PublicApiBaselines.ps1:45,73,87, Merge-PublicApiBaselineSnapshot.ps1:27-35, Repair-PublicApiBaselineHistory.ps1:17, Write-PublicApiChangeSummary.ps1:38) consume the shared helper instead of reimplementing StartsWith('#')/blank checks locally. The convention now has one source of truth, matching how Test-RemovedMarker/Get-RemovedMarkerEntry were already centralized.

3. $LASTEXITCODE leak fragility — fixed at the root cause, not just patched.
scripts/Test-AssertPublicApiBaselines.ps1:30-41 replaces the single end-of-script reset with an Invoke-AssertProcess helper that saves the caller's $LASTEXITCODE before each pwsh -File child invocation and restores it in a finally block at the call site, exactly as requested — this is now independent of script ordering in dotnet.yml. Lines 69-79 add a regression that seeds the caller's exit code to 23 before an external invocation and asserts it survives, which would fail if a future edit reverted to the old end-of-script-only reset.

I also spot-checked the CI wiring (dotnet.yml:107-114 still runs the three test scripts before Assert-PublicApiBaselines.ps1) and the unrelated Command_Header_Precedes_Streamed_Output_And_Completion test fix in CommandLoggerTests.cs (now observes logger calls directly via the existing RecordingLoggerProvider, requires success, and disposes the pipeline in finally) — both look correct and don't reintroduce anything flagged earlier in this thread.

Findings: none blocking. The remaining open item is external to this diff: the author notes a fresh authoritative jq CLI options generation run is in flight and its output still needs to be incorporated and reviewed before merge — that's correctly called out as pending in the PR description, not a defect at this HEAD.

Review: Keep shipped public API entries when recording removals

Re-reviewed at HEAD 0f06c406226fc8fd2fb1f60f7010eb162855ad7c. Since the last CLEAR verdict on this thread (e2bc359), the only change is one commit: chore: Update jq CLI options (#4913).

I traced that commit's actual diff rather than relying on the description:

• src/ModularPipelines.Jq/Generated/Jq.Generation.json: only generatorSourceSha256 changes, reflecting the regenerated generator source (expected, since this PR's script changes affect provenance).
• src/ModularPipelines.Jq/Services/Jq.Generated.cs: no change in this commit (the ConfigureAwait(false) addition already landed in an earlier commit).
• src/ModularPipelines.Jq/PublicAPI.Shipped.txt / PublicAPI.Unshipped.txt: this regeneration run picked up two previously-orphaned *REMOVED* markers for IJq.ExecuteAsync(...) and JqExtensions.Jq(this IPipelineContext) that already existed in PublicAPI.Unshipped.txt on main (i.e., pre-existing orphans, not something this commit introduced), and correctly restored their shipped counterparts into PublicAPI.Shipped.txt via the PR's history-repair logic. I confirmed both files have no duplicate lines (sort | uniq -d is empty for both), and the restored entries match the markers exactly. This is the intended repair behavior, not a bug.

I also independently re-verified the core algorithm directly against the current script content rather than trusting prior summaries, since it's been through many rounds:

• tools/ModularPipelines.OptionsGenerator/scripts/Merge-PublicApiBaselineSnapshot.ps1: shipped entries are never dropped; a *REMOVED* marker is only added when a confirmed removal is present and the entry is still shipped; an existing marker is only carried forward while its entry is still shipped and still absent from the current snapshot; historical shipped entries are correctly recovered from orphaned unshipped markers before classification.
• scripts/Assert-PublicApiBaselines.ps1: single pass per project, reports missing baselines, orphaned markers (including strays in PublicAPI.Shipped.txt), and duplicate entries all in one combined message.
• tools/ModularPipelines.OptionsGenerator/scripts/Write-PublicApiChangeSummary.ps1 and Repair-PublicApiBaselineHistory.ps1: both correctly net markers against entries using the shared, untrimmed comparison, consistent with PublicApiAnalyzers' own exact-match behavior.
• scripts/PublicApiRemovedMarker.ps1 remains the single source of truth for the prefix, parse rule, and blank/header/entry classification, dot-sourced consistently everywhere, and wired into GeneratedOptionsProvenance.ps1's fingerprint.
• test/ModularPipelines.UnitTests/Commands/CommandLoggerTests.cs's Command_Header_Precedes_Streamed_Output_And_Completion now observes logger calls directly via the existing RecordingLoggerProvider/ObserverLogger pattern instead of polling a log file, requires successful execution, and disposes the pipeline in a finally block — a reasonable fix for the flaky Ubuntu wait.
• .github/workflows/dotnet.yml runs Test-PublicApiRemovedMarker.ps1, Test-RepairPublicApiBaselineHistory.ps1, and Test-AssertPublicApiBaselines.ps1 ahead of the real Assert-PublicApiBaselines.ps1 gate, matching the description.
• tools/ModularPipelines.OptionsGenerator/scripts/Test-RepairPublicApiBaselineHistory.ps1 covers retained pairs, signature changes, duplicate-marker dedup, orphan restoration, and idempotency end to end.

This closes out an unusually long and thorough review thread (20+ rounds) where every substantive finding — orphaned-marker root cause, marker-convention triplication, a leftover duplicate migrated line, blank/marker trim inconsistencies, combined-report ordering, duplicate-finding noise, $LASTEXITCODE fragility, and the shipped-file stray-marker gap — was actually fixed rather than deferred, and none has regressed at this head.

No actionable issues found.
