Adopt the Hub Reusable Workflows and Relocate the NuGet Push

[ptr727]

Replaces this repository's three local copies of hub-hosted task workflows with caller stubs pinned to the hub at 2.0.539, and reshapes the publisher so the NuGet push runs from this repository rather than from a hub task.

Second of three PRs against audit run 2026-09-02T00:53:04Z | hub a9afa1d. It closes every remaining interface: and hub-only: finding in that run.

Why the push has to move

NuGet.org validates the OIDC token's job_workflow_ref claim against the package owner, so a push running from ptr727/ProjectTemplate's build-release-task.yml is rejected with HTTP 401 (ptr727/ProjectTemplate#1126). The hub task therefore builds and uploads nuget-build-<branch>, and the new publish-nuget job here downloads that artifact and pushes, which is what makes the claim name this repository.

A smoke build never reaches either push, so no pull request can catch this. The first real release is where it would have surfaced.

The dispatch safeguards, verified rather than assumed

main and develop both dispatch, and they cannot cross channels:

• publish-plan-task.yml accepts workflow_dispatch from main or develop only. Any other ref is a hard ::error:: exit, not a silent skip.
• build-release-task.yml's validate-release job runs before any build or push, and refuses a main version carrying a prerelease suffix, or a non-main version lacking one.
• The GitHub release is stamped prerelease: ${{ inputs.branch != 'main' }}.
• version.json already pins publicReleaseRefSpec to ^refs/heads/main$, so NBGV stamps the suffix correctly on both legs.

The push trigger narrows to main, because the plan task's push arm publishes only for main plus a bot actor, so listing develop would be inert.

What changed

• Deletedbuild-release-task.yml, validate-task.yml, and run-codegen-pull-request-task.yml, per the retire dispositions in the hub's spec/divergences.json.
• publish-release.yml gains the required plan job and the needs.validate.result == 'success' gate the audit reported missing, plus publish-nuget.
• merge-bot-pull-request.yml gains the required merge-bot job as a hub stub.
• test-pull-request.yml gains a changes paths-filter job whose entries are the publisher's own shipped-input list, so the smoke gate and the publish gate agree on what affects the package by construction. CODECOV_TOKEN is mapped explicitly rather than inherited, since secrets: inherit on a cross-repository call would hand the hub validator every secret this repository holds.
• Two new hooks the hub tasks call: .github/actions/validate/action.yml carries the codegen-drift guard that used to live in the local validate task, and .github/actions/codegen/action.yml carries the generator invocation.
• Coverage package swapped from coverlet.MTP to Microsoft.Testing.Extensions.CodeCoverage 18.9.0, which is what the hub validator's coverage invocation drives, per WORKFLOW.md D1.6.
• WORKFLOW.md carried whole from the hub, which brings D9.3's set -Eeuo pipefail with it and closesWorkflows and WORKFLOW.md State set -euo pipefail Where the Hub Requires set -Eeuo pipefail #335.
• OPERATIONS.md corrected in three places where it still described the replaced pipeline, and LanguageTags.slnx's GitHub folder refreshed.

Behavior changes worth knowing

• The GitHub release asset is renamed. The deleted local leaf archived to LanguageTags.7z; the hub default archives to nuget.7z and attaches it as release-asset-<branch>-nuget. Nothing in the repo links the old name.
• A develop -> main promotion merge no longer publishes. That is the point of the plan gate, and it closes the auto-publish gap CodeRabbit raised on Promote develop to main #329. Releasing a promotion is now a deliberate dispatch against main.
• A shipped-input merge to develop no longer publishes a prerelease. A develop prerelease is dispatch-only.
• The nuget.org trusted-publishing policy has already been repointed at publish-release.yml by the maintainer, so the first release after this merge is not blocked on it.

Verification

• All 18 CI checks green, which is the real proof: this is the first run in which the hub reusable workflows actually execute for this repository, including the smoke build going through build-release-task.yml by pin and the codegen-drift guard running as the new validate hook.
• dotnet build: 0 warnings, 0 errors. The offline codegen regeneration produces no drift.
• All four workflows pass actionlint; both composite actions parse.
• Repo gate resolved all 7 hub pins against GitHub. eol, eol-coverage, sha-pin clean.
• Full Docker doc-lint set: 6 linters completed. Diff-scoped prose gate: clean.
• A local strict review pass checked each hub call's input, secret, and permission contract against the task definition at the pinned commit, plus the artifact-name match on the OIDC seam and the job gating. It raised 6 findings; four were real prose gaps this change created, fixed before the PR opened.

Review loop

3 rounds across Copilot, CodeRabbit, and Qodo. 5 threads, all resolved.

Fixed:README.md added to both shipped-input lists, after verifying LanguageTags.csproj packs it (PackageReadmeFile plus a Pack="true" item). Without it a README-only bot push to main would not republish, leaving a stale readme on the gallery page, and a README-only PR would skip the smoke build. The PR title was also 77 characters against the 72-character limit and is now 60.

Declined with evidence: that the smoke build omits ref (it is required: false, default: '', and actions/checkout resolves an empty ref to the triggering event's ref, which on a pull_request is the merge ref; the publish job does pass ref: ${{ github.sha }}, where pinning matters). That GOVERNANCE.md should capitalize "Hub" (lowercase is the carried convention, 31 times in the canonical GOVERNANCE.md alone). And that the .snupkg is never pushed, which is answered in the conversation: the hub action uploads *.snupkg alongside *.nupkg into the artifact, dotnet nuget push pushes a co-located symbol package unless --no-symbols is passed, and the deleted local task carried the identical command, so symbol publishing is unchanged rather than newly broken.

Known remaining

Coverage is PARTIAL, 14 of 15 files, and no round names the unread file. The tooling reports that a re-request has never cleared this and routes the decision to the maintainer.

One suppressed finding stays counted on head, the .snupkg one above. It is declined rather than unanswered; a suppressed finding has no resolve API, so it is counted from the round it is raised in regardless of the answer.

High-Level Assessment

The following are alternative approaches to this PR:

1. Keep the release task local

• ➕ Preserves a repository-local OIDC workflow claim
• ➕ Keeps build, release, and NuGet publication in one reusable workflow
• ➖ Continues duplicating fleet release logic
• ➖ Misses centralized hub fixes and contract improvements
• ➖ Requires this repository to maintain versioning and artifact orchestration

2. Use a long-lived NuGet API key

• ➕ Avoids dependency on the OIDC job_workflow_ref claim
• ➕ Could leave publication inside the hub workflow
• ➖ Introduces a persistent high-value secret
• ➖ Weakens least-privilege and credential-rotation posture
• ➖ Conflicts with the fleet trusted-publishing contract

Recommendation: Use the PR's artifact-handoff design. It centralizes reusable planning, validation, and build behavior while keeping only the identity-sensitive NuGet push local, preserving OIDC trusted publishing and tightly scoping id-token permission. Keeping the entire release task local would solve the claim issue but retain substantial duplicated infrastructure; an API key would solve it at an unacceptable security cost.

🔵 Needs a closer look

It substantially changes release/publish workflow behavior (including OIDC NuGet publishing seams) in ways that are difficult to fully validate without end-to-end release execution.

Pull request overview

This PR adopts the hub’s reusable GitHub Actions workflows (pinned to 2.0.539) and reshapes the release pipeline so the NuGet push executes in this repository’s workflow context (to satisfy NuGet.org OIDC job_workflow_ref validation). It also updates the repo’s workflow/runbook documentation and aligns test coverage tooling with the hub validator.

Changes:

• Replaced locally-carried reusable workflows with caller stubs pinned to the hub, and introduced repo-owned composite hooks for validation (codegen drift guard) and codegen execution.
• Updated the publisher to add a plan gate and moved the NuGet push into a repo-local publish-nuget job that consumes the hub build artifact.
• Swapped coverage tooling from coverlet.MTP to Microsoft.Testing.Extensions.CodeCoverage and refreshed operational/workflow documentation accordingly.

[ptr727]

Answering Qodo's two open findings, which track separately from the review threads.

1. "Smoke build omits ref" (Bug / Correctness). Disproven.

Omitting ref on a smoke call is the contract rather than a gap. Checked against the hub task at the pinned commit a9afa1d:

• build-release-task.yml declares ref as required: false with default: ''. Only branch is required, and both callers here supply it.
• The one use of that input passes it to get-version-task.yml, whose checkout is actions/checkout with ref: ${{ inputs.ref }}. actions/checkout treats an empty ref as unset, resolving to the triggering event's ref, which on a pull_request is the merge ref. So the smoke build versions and packs exactly the tree under review.
• The fleet's reference adoption of this same pattern omits ref on its smoke job too, and supplies it only on the publish job.

publish-release.yml here does pass ref: ${{ github.sha }} on the publish job, because a release must pin the exact commit NBGV versioned rather than a moving ref. Adding it to the smoke job would be actively wrong on a pull_request, where github.sha is the merge commit and pinning it would discard the correct event-ref resolution.

All 18 checks on the reviewed head were green, and that run included the smoke build going through this exact call.

2. "PR title exceeds limit" (Rule violation / Maintainability). Fixed.

The title was 77 characters against the 72-character limit in GOVERNANCE.md "Pull Request Title and Commit Message Conventions". It now reads "Adopt the Hub Reusable Workflows and Relocate the NuGet Push", 60 characters, and the lead commit's subject matches.

🟡 Changes recommended

The new shipped-input path filters omit README.md, but the NuGet package embeds it, so README-only changes won’t trigger smoke/publish and can leave the package readme stale.

🔵 Needs a closer look

The new NuGet publish job only pushes *.nupkg, so the repo’s *.snupkg symbol packages will not be published despite symbols being enabled.

Review details

Suppressed comments (1)

Previously missed (1) — in code that hasn't changed since the last review.

.github/workflows/publish-release.yml:120

• The NuGet publish step only pushes *.nupkg, so the symbol package (*.snupkg) produced by this repo (LanguageTags.csproj sets <IncludeSymbols>true</IncludeSymbols> and SymbolPackageFormat=snupkg) will never be uploaded. This also makes the preceding comment inaccurate: dotnet nuget push does not implicitly upload the co-located .snupkg when you push a .nupkg. Push the .snupkg explicitly (or remove symbol generation).

[ptr727]

Answering the Suppressed comments (1) block from the Copilot review on 015471f, which opens no thread to resolve, and re-answering one Qodo finding that is already fixed.

1. .github/workflows/publish-release.yml:120 — "The NuGet publish step only pushes *.nupkg, so the symbol package (*.snupkg) ... will never be uploaded. This also makes the preceding comment inaccurate: dotnet nuget push does not implicitly upload the co-located .snupkg when you push a .nupkg." Disproven.

The finding is right that this repository produces a .snupkg (LanguageTags.csproj sets IncludeSymbols and SymbolPackageFormat=snupkg) and right that it must reach nuget.org. It is wrong about the mechanism, on two independently checkable points.

The .snupkg is in the artifact. The hub's nuget-build-default/action.yml uploads both patterns into nuget-build-<branch>:

path: | ${{ runner.temp }}/publish/*.nupkg ${{ runner.temp }}/publish/*.snupkg

So after download-artifact into ./nuget, the two files are co-located, which is the precondition the push relies on. (*.nupkg does not glob the .snupkg, since that name ends in .snupkg.)

dotnet nuget push does push a co-located symbol package. That is what its --no-symbols flag exists to suppress: the documented description is "Doesn't push symbols (even if present)", which only means something if the default is to push them. No --no-symbols is passed here.

And this exact mechanism is what has been shipping this package. The build-release-task.yml this PR deletes carried the same command and the same comment, dotnet nuget push .../publish/*.nupkg with no --no-symbols, against a directory holding both files. This PR moves where that step runs, for the OIDC job_workflow_ref reason in the description, and changes nothing about how symbols are pushed. If the claim held, symbol publishing would already have been broken for every release to date rather than newly broken here.

The comment is accurate as written and stays.

2. Qodo, "PR title exceeds limit". Already fixed and reported in a previous comment. The title is now "Adopt the Hub Reusable Workflows and Relocate the NuGet Push", 60 characters against the 72-character limit, and the lead commit subject matches. Qodo appears not to re-evaluate a title change within a run, so the finding stays open on its side with nothing left to do on this one.

[ptr727]

Follow-up now that this has merged and a release has actually run, because two things in this PR could only be proven by a real publish and one of them was a finding I declined.

The publisher was dispatched on develop at run 33592206733. All 12 jobs succeeded, and it produced prerelease 1.5.71-ge44eb09d39.

The relocated OIDC push works. This is the change this PR exists for, and no pull request could exercise it, since a smoke build never reaches a push:

Pushing ***.LanguageTags.1.5.71-ge44eb09d39.nupkg to 'https://www.nuget.org/api/v2/package'...
Created https://www.nuget.org/api/v2/package/ 416ms
Your package was pushed.

No HTTP 401. The job_workflow_ref claim now names this repository's own publish-release.yml, which is what nuget.org validates against the package owner.

The .snupkg finding is settled, and the decline was right. The suppressed finding on publish-release.yml:120 claimed the symbol package "will never be uploaded" and that "dotnet nuget push does not implicitly upload the co-located .snupkg". The same run, same step, immediately after the line above:

Pushing ***.LanguageTags.1.5.71-ge44eb09d39.snupkg to 'https://www.nuget.org/api/v2/symbolpackage'...
Created https://www.nuget.org/api/v2/symbolpackage/ 153ms
Your package was pushed.

One dotnet nuget push ./nuget/*.nupkg invocation, two packages pushed, the symbol one to the symbol server. The comment this PR carries is accurate and no change was owed.

The coverage package swap works.Microsoft.Testing.Extensions.CodeCoverage 18.9.0 under the hub validator's own invocation reported total: 310, failed: 0, succeeded: 310. Worth stating explicitly because the PR description flagged that dotnet test reports "Zero tests ran" on the authoring host: that is confirmed local-only, and it reproduced on a pristine develop checkout there before this change too.

The release-asset rename is confirmed, as the description predicted: the release carries LICENSE, nuget.7z, and README.md, where previous releases carried LanguageTags.7z.

One observation, pre-existing rather than introduced here: the develop prerelease is 1.5.71 while main is at 1.5.90, because NBGV computes git height and develop takes squash merges (one commit each) while main takes merge commits (which bring the whole develop commit list). The previous develop prerelease sat at 1.5.65 against a 1.5.88 main for the same reason. Flagging it rather than treating it as this PR's business.

[ptr727]

Replaces this repository's three local copies of hub-hosted task workflows with caller stubs pinned to the hub at 2.0.539, and reshapes the publisher so the NuGet push runs from this repository rather than from a hub task.

Second of three PRs against audit run 2026-09-02T00:53:04Z | hub a9afa1d. It closes every remaining interface: and hub-only: finding in that run.

Why the push has to move

NuGet.org validates the OIDC token's job_workflow_ref claim against the package owner, so a push running from ptr727/ProjectTemplate's build-release-task.yml is rejected with HTTP 401 (ptr727/ProjectTemplate#1126). The hub task therefore builds and uploads nuget-build-<branch>, and the new publish-nuget job here downloads that artifact and pushes, which is what makes the claim name this repository.

A smoke build never reaches either push, so no pull request can catch this. The first real release is where it would have surfaced.

The dispatch safeguards, verified rather than assumed

main and develop both dispatch, and they cannot cross channels:

• publish-plan-task.yml accepts workflow_dispatch from main or develop only. Any other ref is a hard ::error:: exit, not a silent skip.
• build-release-task.yml's validate-release job runs before any build or push, and refuses a main version carrying a prerelease suffix, or a non-main version lacking one.
• The GitHub release is stamped prerelease: ${{ inputs.branch != 'main' }}.
• version.json already pins publicReleaseRefSpec to ^refs/heads/main$, so NBGV stamps the suffix correctly on both legs.

The push trigger narrows to main, because the plan task's push arm publishes only for main plus a bot actor, so listing develop would be inert.

What changed

• Deletedbuild-release-task.yml, validate-task.yml, and run-codegen-pull-request-task.yml, per the retire dispositions in the hub's spec/divergences.json.
• publish-release.yml gains the required plan job and the needs.validate.result == 'success' gate the audit reported missing, plus publish-nuget.
• merge-bot-pull-request.yml gains the required merge-bot job as a hub stub.
• test-pull-request.yml gains a changes paths-filter job whose entries are the publisher's own shipped-input list, so the smoke gate and the publish gate agree on what affects the package by construction. CODECOV_TOKEN is mapped explicitly rather than inherited, since secrets: inherit on a cross-repository call would hand the hub validator every secret this repository holds.
• Two new hooks the hub tasks call: .github/actions/validate/action.yml carries the codegen-drift guard that used to live in the local validate task, and .github/actions/codegen/action.yml carries the generator invocation.
• Coverage package swapped from coverlet.MTP to Microsoft.Testing.Extensions.CodeCoverage 18.9.0, which is what the hub validator's coverage invocation drives, per WORKFLOW.md D1.6.
• WORKFLOW.md carried whole from the hub, which brings D9.3's set -Eeuo pipefail with it and closesWorkflows and WORKFLOW.md State set -euo pipefail Where the Hub Requires set -Eeuo pipefail #335.
• OPERATIONS.md corrected in three places where it still described the replaced pipeline, and LanguageTags.slnx's GitHub folder refreshed.

Behavior changes worth knowing

• The GitHub release asset is renamed. The deleted local leaf archived to LanguageTags.7z; the hub default archives to nuget.7z and attaches it as release-asset-<branch>-nuget. Nothing in the repo links the old name.
• A develop -> main promotion merge no longer publishes. That is the point of the plan gate, and it closes the auto-publish gap CodeRabbit raised on Promote develop to main #329. Releasing a promotion is now a deliberate dispatch against main.
• A shipped-input merge to develop no longer publishes a prerelease. A develop prerelease is dispatch-only.
• The nuget.org trusted-publishing policy has already been repointed at publish-release.yml by the maintainer, so the first release after this merge is not blocked on it.

Verification

• All 18 CI checks green, which is the real proof: this is the first run in which the hub reusable workflows actually execute for this repository, including the smoke build going through build-release-task.yml by pin and the codegen-drift guard running as the new validate hook.
• dotnet build: 0 warnings, 0 errors. The offline codegen regeneration produces no drift.
• All four workflows pass actionlint; both composite actions parse.
• Repo gate resolved all 7 hub pins against GitHub. eol, eol-coverage, sha-pin clean.
• Full Docker doc-lint set: 6 linters completed. Diff-scoped prose gate: clean.
• A local strict review pass checked each hub call's input, secret, and permission contract against the task definition at the pinned commit, plus the artifact-name match on the OIDC seam and the job gating. It raised 6 findings; four were real prose gaps this change created, fixed before the PR opened.

Review loop

3 rounds across Copilot, CodeRabbit, and Qodo. 5 threads, all resolved.

Fixed:README.md added to both shipped-input lists, after verifying LanguageTags.csproj packs it (PackageReadmeFile plus a Pack="true" item). Without it a README-only bot push to main would not republish, leaving a stale readme on the gallery page, and a README-only PR would skip the smoke build. The PR title was also 77 characters against the 72-character limit and is now 60.

Declined with evidence: that the smoke build omits ref (it is required: false, default: '', and actions/checkout resolves an empty ref to the triggering event's ref, which on a pull_request is the merge ref; the publish job does pass ref: ${{ github.sha }}, where pinning matters). That GOVERNANCE.md should capitalize "Hub" (lowercase is the carried convention, 31 times in the canonical GOVERNANCE.md alone). And that the .snupkg is never pushed, which is answered in the conversation: the hub action uploads *.snupkg alongside *.nupkg into the artifact, dotnet nuget push pushes a co-located symbol package unless --no-symbols is passed, and the deleted local task carried the identical command, so symbol publishing is unchanged rather than newly broken.

Known remaining

Coverage is PARTIAL, 14 of 15 files, and no round names the unread file. The tooling reports that a re-request has never cleared this and routes the decision to the maintainer.

One suppressed finding stays counted on head, the .snupkg one above. It is declined rather than unanswered; a suppressed finding has no resolve API, so it is counted from the round it is raised in regardless of the answer.

High-Level Assessment

The following are alternative approaches to this PR:

1. Keep the release task local

• ➕ Preserves a repository-local OIDC workflow claim
• ➕ Keeps build, release, and NuGet publication in one reusable workflow
• ➖ Continues duplicating fleet release logic
• ➖ Misses centralized hub fixes and contract improvements
• ➖ Requires this repository to maintain versioning and artifact orchestration

2. Use a long-lived NuGet API key

• ➕ Avoids dependency on the OIDC job_workflow_ref claim
• ➕ Could leave publication inside the hub workflow
• ➖ Introduces a persistent high-value secret
• ➖ Weakens least-privilege and credential-rotation posture
• ➖ Conflicts with the fleet trusted-publishing contract

Recommendation: Use the PR's artifact-handoff design. It centralizes reusable planning, validation, and build behavior while keeping only the identity-sensitive NuGet push local, preserving OIDC trusted publishing and tightly scoping id-token permission. Keeping the entire release task local would solve the claim issue but retain substantial duplicated infrastructure; an API key would solve it at an unacceptable security cost.

This PR adopts the hub’s reusable GitHub Actions workflows (pinned to 2.0.539) and reshapes the release pipeline so the NuGet push executes in this repository’s workflow context (to satisfy NuGet.org OIDC job_workflow_ref validation). It also updates the repo’s workflow/runbook documentation and aligns test coverage tooling with the hub validator.

Changes:

• Replaced locally-carried reusable workflows with caller stubs pinned to the hub, and introduced repo-owned composite hooks for validation (codegen drift guard) and codegen execution.
• Updated the publisher to add a plan gate and moved the NuGet push into a repo-local publish-nuget job that consumes the hub build artifact.
• Swapped coverage tooling from coverlet.MTP to Microsoft.Testing.Extensions.CodeCoverage and refreshed operational/workflow documentation accordingly.

[ptr727]

Answering Qodo's two open findings, which track separately from the review threads.

1. "Smoke build omits ref" (Bug / Correctness). Disproven.

Omitting ref on a smoke call is the contract rather than a gap. Checked against the hub task at the pinned commit a9afa1d:

• build-release-task.yml declares ref as required: false with default: ''. Only branch is required, and both callers here supply it.
• The one use of that input passes it to get-version-task.yml, whose checkout is actions/checkout with ref: ${{ inputs.ref }}. actions/checkout treats an empty ref as unset, resolving to the triggering event's ref, which on a pull_request is the merge ref. So the smoke build versions and packs exactly the tree under review.
• The fleet's reference adoption of this same pattern omits ref on its smoke job too, and supplies it only on the publish job.

publish-release.yml here does pass ref: ${{ github.sha }} on the publish job, because a release must pin the exact commit NBGV versioned rather than a moving ref. Adding it to the smoke job would be actively wrong on a pull_request, where github.sha is the merge commit and pinning it would discard the correct event-ref resolution.

All 18 checks on the reviewed head were green, and that run included the smoke build going through this exact call.

2. "PR title exceeds limit" (Rule violation / Maintainability). Fixed.

The title was 77 characters against the 72-character limit in GOVERNANCE.md "Pull Request Title and Commit Message Conventions". It now reads "Adopt the Hub Reusable Workflows and Relocate the NuGet Push", 60 characters, and the lead commit's subject matches.

🟡 Changes recommended

The new shipped-input path filters omit README.md, but the NuGet package embeds it, so README-only changes won’t trigger smoke/publish and can leave the package readme stale.

Once you've addressed the issues Copilot identified, you can request another Copilot review.

🔵 Needs a closer look

The new NuGet publish job only pushes *.nupkg, so the repo’s *.snupkg symbol packages will not be published despite symbols being enabled.

Review details

Suppressed comments (1)

Previously missed (1) — in code that hasn't changed since the last review.

.github/workflows/publish-release.yml:120

• The NuGet publish step only pushes *.nupkg, so the symbol package (*.snupkg) produced by this repo (LanguageTags.csproj sets <IncludeSymbols>true</IncludeSymbols> and SymbolPackageFormat=snupkg) will never be uploaded. This also makes the preceding comment inaccurate: dotnet nuget push does not implicitly upload the co-located .snupkg when you push a .nupkg. Push the .snupkg explicitly (or remove symbol generation).

Answering the Suppressed comments (1) block from the Copilot review on 015471f, which opens no thread to resolve, and re-answering one Qodo finding that is already fixed.

1. .github/workflows/publish-release.yml:120 — "The NuGet publish step only pushes *.nupkg, so the symbol package (*.snupkg) ... will never be uploaded. This also makes the preceding comment inaccurate: dotnet nuget push does not implicitly upload the co-located .snupkg when you push a .nupkg." Disproven.

The finding is right that this repository produces a .snupkg (LanguageTags.csproj sets IncludeSymbols and SymbolPackageFormat=snupkg) and right that it must reach nuget.org. It is wrong about the mechanism, on two independently checkable points.

The .snupkg is in the artifact. The hub's nuget-build-default/action.yml uploads both patterns into nuget-build-<branch>:

path: | ${{ runner.temp }}/publish/*.nupkg ${{ runner.temp }}/publish/*.snupkg

So after download-artifact into ./nuget, the two files are co-located, which is the precondition the push relies on. (*.nupkg does not glob the .snupkg, since that name ends in .snupkg.)

dotnet nuget push does push a co-located symbol package. That is what its --no-symbols flag exists to suppress: the documented description is "Doesn't push symbols (even if present)", which only means something if the default is to push them. No --no-symbols is passed here.

And this exact mechanism is what has been shipping this package. The build-release-task.yml this PR deletes carried the same command and the same comment, dotnet nuget push .../publish/*.nupkg with no --no-symbols, against a directory holding both files. This PR moves where that step runs, for the OIDC job_workflow_ref reason in the description, and changes nothing about how symbols are pushed. If the claim held, symbol publishing would already have been broken for every release to date rather than newly broken here.

The comment is accurate as written and stays.

2. Qodo, "PR title exceeds limit". Already fixed and reported in a previous comment. The title is now "Adopt the Hub Reusable Workflows and Relocate the NuGet Push", 60 characters against the 72-character limit, and the lead commit subject matches. Qodo appears not to re-evaluate a title change within a run, so the finding stays open on its side with nothing left to do on this one.

[ptr727]

Follow-up now that this has merged and a release has actually run, because two things in this PR could only be proven by a real publish and one of them was a finding I declined.

The publisher was dispatched on develop at run 33592206733. All 12 jobs succeeded, and it produced prerelease 1.5.71-ge44eb09d39.

The relocated OIDC push works. This is the change this PR exists for, and no pull request could exercise it, since a smoke build never reaches a push:

Pushing ***.LanguageTags.1.5.71-ge44eb09d39.nupkg to 'https://www.nuget.org/api/v2/package'...
Created https://www.nuget.org/api/v2/package/ 416ms
Your package was pushed.

No HTTP 401. The job_workflow_ref claim now names this repository's own publish-release.yml, which is what nuget.org validates against the package owner.

The .snupkg finding is settled, and the decline was right. The suppressed finding on publish-release.yml:120 claimed the symbol package "will never be uploaded" and that "dotnet nuget push does not implicitly upload the co-located .snupkg". The same run, same step, immediately after the line above:

Pushing ***.LanguageTags.1.5.71-ge44eb09d39.snupkg to 'https://www.nuget.org/api/v2/symbolpackage'...
Created https://www.nuget.org/api/v2/symbolpackage/ 153ms
Your package was pushed.

One dotnet nuget push ./nuget/*.nupkg invocation, two packages pushed, the symbol one to the symbol server. The comment this PR carries is accurate and no change was owed.

The coverage package swap works.Microsoft.Testing.Extensions.CodeCoverage 18.9.0 under the hub validator's own invocation reported total: 310, failed: 0, succeeded: 310. Worth stating explicitly because the PR description flagged that dotnet test reports "Zero tests ran" on the authoring host: that is confirmed local-only, and it reproduced on a pristine develop checkout there before this change too.

The release-asset rename is confirmed, as the description predicted: the release carries LICENSE, nuget.7z, and README.md, where previous releases carried LanguageTags.7z.

One observation, pre-existing rather than introduced here: the develop prerelease is 1.5.71 while main is at 1.5.90, because NBGV computes git height and develop takes squash merges (one commit each) while main takes merge commits (which bring the whole develop commit list). The previous develop prerelease sat at 1.5.65 against a 1.5.88 main for the same reason. Flagging it rather than treating it as this PR's business.

[ptr727]

Replaces this repository's three local copies of hub-hosted task workflows with caller stubs pinned to the hub at 2.0.539, and reshapes the publisher so the NuGet push runs from this repository rather than from a hub task.

Second of three PRs against audit run 2026-09-02T00:53:04Z | hub a9afa1d. It closes every remaining interface: and hub-only: finding in that run.

Why the push has to move

NuGet.org validates the OIDC token's job_workflow_ref claim against the package owner, so a push running from ptr727/ProjectTemplate's build-release-task.yml is rejected with HTTP 401 (ptr727/ProjectTemplate#1126). The hub task therefore builds and uploads nuget-build-<branch>, and the new publish-nuget job here downloads that artifact and pushes, which is what makes the claim name this repository.

A smoke build never reaches either push, so no pull request can catch this. The first real release is where it would have surfaced.

The dispatch safeguards, verified rather than assumed

main and develop both dispatch, and they cannot cross channels:

• publish-plan-task.yml accepts workflow_dispatch from main or develop only. Any other ref is a hard ::error:: exit, not a silent skip.
• build-release-task.yml's validate-release job runs before any build or push, and refuses a main version carrying a prerelease suffix, or a non-main version lacking one.
• The GitHub release is stamped prerelease: ${{ inputs.branch != 'main' }}.
• version.json already pins publicReleaseRefSpec to ^refs/heads/main$, so NBGV stamps the suffix correctly on both legs.

The push trigger narrows to main, because the plan task's push arm publishes only for main plus a bot actor, so listing develop would be inert.

What changed

• Deletedbuild-release-task.yml, validate-task.yml, and run-codegen-pull-request-task.yml, per the retire dispositions in the hub's spec/divergences.json.
• publish-release.yml gains the required plan job and the needs.validate.result == 'success' gate the audit reported missing, plus publish-nuget.
• merge-bot-pull-request.yml gains the required merge-bot job as a hub stub.
• test-pull-request.yml gains a changes paths-filter job whose entries are the publisher's own shipped-input list, so the smoke gate and the publish gate agree on what affects the package by construction. CODECOV_TOKEN is mapped explicitly rather than inherited, since secrets: inherit on a cross-repository call would hand the hub validator every secret this repository holds.
• Two new hooks the hub tasks call: .github/actions/validate/action.yml carries the codegen-drift guard that used to live in the local validate task, and .github/actions/codegen/action.yml carries the generator invocation.
• Coverage package swapped from coverlet.MTP to Microsoft.Testing.Extensions.CodeCoverage 18.9.0, which is what the hub validator's coverage invocation drives, per WORKFLOW.md D1.6.
• WORKFLOW.md carried whole from the hub, which brings D9.3's set -Eeuo pipefail with it and closesWorkflows and WORKFLOW.md State set -euo pipefail Where the Hub Requires set -Eeuo pipefail #335.
• OPERATIONS.md corrected in three places where it still described the replaced pipeline, and LanguageTags.slnx's GitHub folder refreshed.

Behavior changes worth knowing

• The GitHub release asset is renamed. The deleted local leaf archived to LanguageTags.7z; the hub default archives to nuget.7z and attaches it as release-asset-<branch>-nuget. Nothing in the repo links the old name.
• A develop -> main promotion merge no longer publishes. That is the point of the plan gate, and it closes the auto-publish gap CodeRabbit raised on Promote develop to main #329. Releasing a promotion is now a deliberate dispatch against main.
• A shipped-input merge to develop no longer publishes a prerelease. A develop prerelease is dispatch-only.
• The nuget.org trusted-publishing policy has already been repointed at publish-release.yml by the maintainer, so the first release after this merge is not blocked on it.

Verification

• All 18 CI checks green, which is the real proof: this is the first run in which the hub reusable workflows actually execute for this repository, including the smoke build going through build-release-task.yml by pin and the codegen-drift guard running as the new validate hook.
• dotnet build: 0 warnings, 0 errors. The offline codegen regeneration produces no drift.
• All four workflows pass actionlint; both composite actions parse.
• Repo gate resolved all 7 hub pins against GitHub. eol, eol-coverage, sha-pin clean.
• Full Docker doc-lint set: 6 linters completed. Diff-scoped prose gate: clean.
• A local strict review pass checked each hub call's input, secret, and permission contract against the task definition at the pinned commit, plus the artifact-name match on the OIDC seam and the job gating. It raised 6 findings; four were real prose gaps this change created, fixed before the PR opened.

Review loop

3 rounds across Copilot, CodeRabbit, and Qodo. 5 threads, all resolved.

Fixed:README.md added to both shipped-input lists, after verifying LanguageTags.csproj packs it (PackageReadmeFile plus a Pack="true" item). Without it a README-only bot push to main would not republish, leaving a stale readme on the gallery page, and a README-only PR would skip the smoke build. The PR title was also 77 characters against the 72-character limit and is now 60.

Declined with evidence: that the smoke build omits ref (it is required: false, default: '', and actions/checkout resolves an empty ref to the triggering event's ref, which on a pull_request is the merge ref; the publish job does pass ref: ${{ github.sha }}, where pinning matters). That GOVERNANCE.md should capitalize "Hub" (lowercase is the carried convention, 31 times in the canonical GOVERNANCE.md alone). And that the .snupkg is never pushed, which is answered in the conversation: the hub action uploads *.snupkg alongside *.nupkg into the artifact, dotnet nuget push pushes a co-located symbol package unless --no-symbols is passed, and the deleted local task carried the identical command, so symbol publishing is unchanged rather than newly broken.

Known remaining

Coverage is PARTIAL, 14 of 15 files, and no round names the unread file. The tooling reports that a re-request has never cleared this and routes the decision to the maintainer.

One suppressed finding stays counted on head, the .snupkg one above. It is declined rather than unanswered; a suppressed finding has no resolve API, so it is counted from the round it is raised in regardless of the answer.

High-Level Assessment

The following are alternative approaches to this PR:

1. Keep the release task local

• ➕ Preserves a repository-local OIDC workflow claim
• ➕ Keeps build, release, and NuGet publication in one reusable workflow
• ➖ Continues duplicating fleet release logic
• ➖ Misses centralized hub fixes and contract improvements
• ➖ Requires this repository to maintain versioning and artifact orchestration

2. Use a long-lived NuGet API key

• ➕ Avoids dependency on the OIDC job_workflow_ref claim
• ➕ Could leave publication inside the hub workflow
• ➖ Introduces a persistent high-value secret
• ➖ Weakens least-privilege and credential-rotation posture
• ➖ Conflicts with the fleet trusted-publishing contract

Recommendation: Use the PR's artifact-handoff design. It centralizes reusable planning, validation, and build behavior while keeping only the identity-sensitive NuGet push local, preserving OIDC trusted publishing and tightly scoping id-token permission. Keeping the entire release task local would solve the claim issue but retain substantial duplicated infrastructure; an API key would solve it at an unacceptable security cost.

🔵 Needs a closer look

It substantially changes release/publish workflow behavior (including OIDC NuGet publishing seams) in ways that are difficult to fully validate without end-to-end release execution.

Pull request overview

This PR adopts the hub’s reusable GitHub Actions workflows (pinned to 2.0.539) and reshapes the release pipeline so the NuGet push executes in this repository’s workflow context (to satisfy NuGet.org OIDC job_workflow_ref validation). It also updates the repo’s workflow/runbook documentation and aligns test coverage tooling with the hub validator.

Changes:

• Replaced locally-carried reusable workflows with caller stubs pinned to the hub, and introduced repo-owned composite hooks for validation (codegen drift guard) and codegen execution.
• Updated the publisher to add a plan gate and moved the NuGet push into a repo-local publish-nuget job that consumes the hub build artifact.
• Swapped coverage tooling from coverlet.MTP to Microsoft.Testing.Extensions.CodeCoverage and refreshed operational/workflow documentation accordingly.

File summaries

[ptr727]

Answering Qodo's two open findings, which track separately from the review threads.

1. "Smoke build omits ref" (Bug / Correctness). Disproven.

Omitting ref on a smoke call is the contract rather than a gap. Checked against the hub task at the pinned commit a9afa1d:

• build-release-task.yml declares ref as required: false with default: ''. Only branch is required, and both callers here supply it.
• The one use of that input passes it to get-version-task.yml, whose checkout is actions/checkout with ref: ${{ inputs.ref }}. actions/checkout treats an empty ref as unset, resolving to the triggering event's ref, which on a pull_request is the merge ref. So the smoke build versions and packs exactly the tree under review.
• The fleet's reference adoption of this same pattern omits ref on its smoke job too, and supplies it only on the publish job.

publish-release.yml here does pass ref: ${{ github.sha }} on the publish job, because a release must pin the exact commit NBGV versioned rather than a moving ref. Adding it to the smoke job would be actively wrong on a pull_request, where github.sha is the merge commit and pinning it would discard the correct event-ref resolution.

All 18 checks on the reviewed head were green, and that run included the smoke build going through this exact call.

2. "PR title exceeds limit" (Rule violation / Maintainability). Fixed.

The title was 77 characters against the 72-character limit in GOVERNANCE.md "Pull Request Title and Commit Message Conventions". It now reads "Adopt the Hub Reusable Workflows and Relocate the NuGet Push", 60 characters, and the lead commit's subject matches.

🟡 Changes recommended

The new shipped-input path filters omit README.md, but the NuGet package embeds it, so README-only changes won’t trigger smoke/publish and can leave the package readme stale.

🔵 Needs a closer look

The new NuGet publish job only pushes *.nupkg, so the repo’s *.snupkg symbol packages will not be published despite symbols being enabled.

Review details

Suppressed comments (1)

Previously missed (1) — in code that hasn't changed since the last review.

.github/workflows/publish-release.yml:120

• The NuGet publish step only pushes *.nupkg, so the symbol package (*.snupkg) produced by this repo (LanguageTags.csproj sets <IncludeSymbols>true</IncludeSymbols> and SymbolPackageFormat=snupkg) will never be uploaded. This also makes the preceding comment inaccurate: dotnet nuget push does not implicitly upload the co-located .snupkg when you push a .nupkg. Push the .snupkg explicitly (or remove symbol generation).

[ptr727]

Answering the Suppressed comments (1) block from the Copilot review on 015471f, which opens no thread to resolve, and re-answering one Qodo finding that is already fixed.

1. .github/workflows/publish-release.yml:120 — "The NuGet publish step only pushes *.nupkg, so the symbol package (*.snupkg) ... will never be uploaded. This also makes the preceding comment inaccurate: dotnet nuget push does not implicitly upload the co-located .snupkg when you push a .nupkg." Disproven.

The finding is right that this repository produces a .snupkg (LanguageTags.csproj sets IncludeSymbols and SymbolPackageFormat=snupkg) and right that it must reach nuget.org. It is wrong about the mechanism, on two independently checkable points.

The .snupkg is in the artifact. The hub's nuget-build-default/action.yml uploads both patterns into nuget-build-<branch>:

path: | ${{ runner.temp }}/publish/*.nupkg ${{ runner.temp }}/publish/*.snupkg

So after download-artifact into ./nuget, the two files are co-located, which is the precondition the push relies on. (*.nupkg does not glob the .snupkg, since that name ends in .snupkg.)

dotnet nuget push does push a co-located symbol package. That is what its --no-symbols flag exists to suppress: the documented description is "Doesn't push symbols (even if present)", which only means something if the default is to push them. No --no-symbols is passed here.

And this exact mechanism is what has been shipping this package. The build-release-task.yml this PR deletes carried the same command and the same comment, dotnet nuget push .../publish/*.nupkg with no --no-symbols, against a directory holding both files. This PR moves where that step runs, for the OIDC job_workflow_ref reason in the description, and changes nothing about how symbols are pushed. If the claim held, symbol publishing would already have been broken for every release to date rather than newly broken here.

The comment is accurate as written and stays.

2. Qodo, "PR title exceeds limit". Already fixed and reported in a previous comment. The title is now "Adopt the Hub Reusable Workflows and Relocate the NuGet Push", 60 characters against the 72-character limit, and the lead commit subject matches. Qodo appears not to re-evaluate a title change within a run, so the finding stays open on its side with nothing left to do on this one.

[ptr727]

Follow-up now that this has merged and a release has actually run, because two things in this PR could only be proven by a real publish and one of them was a finding I declined.

The publisher was dispatched on develop at run 33592206733. All 12 jobs succeeded, and it produced prerelease 1.5.71-ge44eb09d39.

The relocated OIDC push works. This is the change this PR exists for, and no pull request could exercise it, since a smoke build never reaches a push:

Pushing ***.LanguageTags.1.5.71-ge44eb09d39.nupkg to 'https://www.nuget.org/api/v2/package'...
Created https://www.nuget.org/api/v2/package/ 416ms
Your package was pushed.

No HTTP 401. The job_workflow_ref claim now names this repository's own publish-release.yml, which is what nuget.org validates against the package owner.

The .snupkg finding is settled, and the decline was right. The suppressed finding on publish-release.yml:120 claimed the symbol package "will never be uploaded" and that "dotnet nuget push does not implicitly upload the co-located .snupkg". The same run, same step, immediately after the line above:

Pushing ***.LanguageTags.1.5.71-ge44eb09d39.snupkg to 'https://www.nuget.org/api/v2/symbolpackage'...
Created https://www.nuget.org/api/v2/symbolpackage/ 153ms
Your package was pushed.

One dotnet nuget push ./nuget/*.nupkg invocation, two packages pushed, the symbol one to the symbol server. The comment this PR carries is accurate and no change was owed.

The coverage package swap works.Microsoft.Testing.Extensions.CodeCoverage 18.9.0 under the hub validator's own invocation reported total: 310, failed: 0, succeeded: 310. Worth stating explicitly because the PR description flagged that dotnet test reports "Zero tests ran" on the authoring host: that is confirmed local-only, and it reproduced on a pristine develop checkout there before this change too.

The release-asset rename is confirmed, as the description predicted: the release carries LICENSE, nuget.7z, and README.md, where previous releases carried LanguageTags.7z.

One observation, pre-existing rather than introduced here: the develop prerelease is 1.5.71 while main is at 1.5.90, because NBGV computes git height and develop takes squash merges (one commit each) while main takes merge commits (which bring the whole develop commit list). The previous develop prerelease sat at 1.5.65 against a 1.5.88 main for the same reason. Flagging it rather than treating it as this PR's business.

[ptr727]

Replaces this repository's three local copies of hub-hosted task workflows with caller stubs pinned to the hub at 2.0.539, and reshapes the publisher so the NuGet push runs from this repository rather than from a hub task.

Second of three PRs against audit run 2026-09-02T00:53:04Z | hub a9afa1d. It closes every remaining interface: and hub-only: finding in that run.

Why the push has to move

NuGet.org validates the OIDC token's job_workflow_ref claim against the package owner, so a push running from ptr727/ProjectTemplate's build-release-task.yml is rejected with HTTP 401 (ptr727/ProjectTemplate#1126). The hub task therefore builds and uploads nuget-build-<branch>, and the new publish-nuget job here downloads that artifact and pushes, which is what makes the claim name this repository.

A smoke build never reaches either push, so no pull request can catch this. The first real release is where it would have surfaced.

The dispatch safeguards, verified rather than assumed

main and develop both dispatch, and they cannot cross channels:

• publish-plan-task.yml accepts workflow_dispatch from main or develop only. Any other ref is a hard ::error:: exit, not a silent skip.
• build-release-task.yml's validate-release job runs before any build or push, and refuses a main version carrying a prerelease suffix, or a non-main version lacking one.
• The GitHub release is stamped prerelease: ${{ inputs.branch != 'main' }}.
• version.json already pins publicReleaseRefSpec to ^refs/heads/main$, so NBGV stamps the suffix correctly on both legs.

The push trigger narrows to main, because the plan task's push arm publishes only for main plus a bot actor, so listing develop would be inert.

What changed

• Deletedbuild-release-task.yml, validate-task.yml, and run-codegen-pull-request-task.yml, per the retire dispositions in the hub's spec/divergences.json.
• publish-release.yml gains the required plan job and the needs.validate.result == 'success' gate the audit reported missing, plus publish-nuget.
• merge-bot-pull-request.yml gains the required merge-bot job as a hub stub.
• test-pull-request.yml gains a changes paths-filter job whose entries are the publisher's own shipped-input list, so the smoke gate and the publish gate agree on what affects the package by construction. CODECOV_TOKEN is mapped explicitly rather than inherited, since secrets: inherit on a cross-repository call would hand the hub validator every secret this repository holds.
• Two new hooks the hub tasks call: .github/actions/validate/action.yml carries the codegen-drift guard that used to live in the local validate task, and .github/actions/codegen/action.yml carries the generator invocation.
• Coverage package swapped from coverlet.MTP to Microsoft.Testing.Extensions.CodeCoverage 18.9.0, which is what the hub validator's coverage invocation drives, per WORKFLOW.md D1.6.
• WORKFLOW.md carried whole from the hub, which brings D9.3's set -Eeuo pipefail with it and closesWorkflows and WORKFLOW.md State set -euo pipefail Where the Hub Requires set -Eeuo pipefail #335.
• OPERATIONS.md corrected in three places where it still described the replaced pipeline, and LanguageTags.slnx's GitHub folder refreshed.

Behavior changes worth knowing

• The GitHub release asset is renamed. The deleted local leaf archived to LanguageTags.7z; the hub default archives to nuget.7z and attaches it as release-asset-<branch>-nuget. Nothing in the repo links the old name.
• A develop -> main promotion merge no longer publishes. That is the point of the plan gate, and it closes the auto-publish gap CodeRabbit raised on Promote develop to main #329. Releasing a promotion is now a deliberate dispatch against main.
• A shipped-input merge to develop no longer publishes a prerelease. A develop prerelease is dispatch-only.
• The nuget.org trusted-publishing policy has already been repointed at publish-release.yml by the maintainer, so the first release after this merge is not blocked on it.

Verification

• All 18 CI checks green, which is the real proof: this is the first run in which the hub reusable workflows actually execute for this repository, including the smoke build going through build-release-task.yml by pin and the codegen-drift guard running as the new validate hook.
• dotnet build: 0 warnings, 0 errors. The offline codegen regeneration produces no drift.
• All four workflows pass actionlint; both composite actions parse.
• Repo gate resolved all 7 hub pins against GitHub. eol, eol-coverage, sha-pin clean.
• Full Docker doc-lint set: 6 linters completed. Diff-scoped prose gate: clean.
• A local strict review pass checked each hub call's input, secret, and permission contract against the task definition at the pinned commit, plus the artifact-name match on the OIDC seam and the job gating. It raised 6 findings; four were real prose gaps this change created, fixed before the PR opened.

Review loop

3 rounds across Copilot, CodeRabbit, and Qodo. 5 threads, all resolved.

Fixed:README.md added to both shipped-input lists, after verifying LanguageTags.csproj packs it (PackageReadmeFile plus a Pack="true" item). Without it a README-only bot push to main would not republish, leaving a stale readme on the gallery page, and a README-only PR would skip the smoke build. The PR title was also 77 characters against the 72-character limit and is now 60.

Declined with evidence: that the smoke build omits ref (it is required: false, default: '', and actions/checkout resolves an empty ref to the triggering event's ref, which on a pull_request is the merge ref; the publish job does pass ref: ${{ github.sha }}, where pinning matters). That GOVERNANCE.md should capitalize "Hub" (lowercase is the carried convention, 31 times in the canonical GOVERNANCE.md alone). And that the .snupkg is never pushed, which is answered in the conversation: the hub action uploads *.snupkg alongside *.nupkg into the artifact, dotnet nuget push pushes a co-located symbol package unless --no-symbols is passed, and the deleted local task carried the identical command, so symbol publishing is unchanged rather than newly broken.

Known remaining

Coverage is PARTIAL, 14 of 15 files, and no round names the unread file. The tooling reports that a re-request has never cleared this and routes the decision to the maintainer.

One suppressed finding stays counted on head, the .snupkg one above. It is declined rather than unanswered; a suppressed finding has no resolve API, so it is counted from the round it is raised in regardless of the answer.

High-Level Assessment

The following are alternative approaches to this PR:

1. Keep the release task local

• ➕ Preserves a repository-local OIDC workflow claim
• ➕ Keeps build, release, and NuGet publication in one reusable workflow
• ➖ Continues duplicating fleet release logic
• ➖ Misses centralized hub fixes and contract improvements
• ➖ Requires this repository to maintain versioning and artifact orchestration

2. Use a long-lived NuGet API key

• ➕ Avoids dependency on the OIDC job_workflow_ref claim
• ➕ Could leave publication inside the hub workflow
• ➖ Introduces a persistent high-value secret
• ➖ Weakens least-privilege and credential-rotation posture
• ➖ Conflicts with the fleet trusted-publishing contract

Recommendation: Use the PR's artifact-handoff design. It centralizes reusable planning, validation, and build behavior while keeping only the identity-sensitive NuGet push local, preserving OIDC trusted publishing and tightly scoping id-token permission. Keeping the entire release task local would solve the claim issue but retain substantial duplicated infrastructure; an API key would solve it at an unacceptable security cost.

1. Smoke build omits ref✗ Dismissed🐞 Bug≡ Correctness

Description

The new smoke-build call does not pass the required ref input to build-release-task.yml, so
target-changing pull requests cannot successfully invoke the reusable build. The required aggregator
will consequently fail instead of validating the package.

The reusable smoke-build invocation omits the required `ref` input, preventing the hub build task from receiving the commit it must check out and build.
## Issue Context
The reusable-task contract requires the release task to take `ref`, `branch`, and the relevant `smoke` value. The publishing invocation already passes `ref: ${{ github.sha }}`, but the pull-request smoke invocation does not.

🔵 Needs a closer look

It substantially changes release/publish workflow behavior (including OIDC NuGet publishing seams) in ways that are difficult to fully validate without end-to-end release execution.

Pull request overview

This PR adopts the hub’s reusable GitHub Actions workflows (pinned to 2.0.539) and reshapes the release pipeline so the NuGet push executes in this repository’s workflow context (to satisfy NuGet.org OIDC job_workflow_ref validation). It also updates the repo’s workflow/runbook documentation and aligns test coverage tooling with the hub validator.

Changes:

• Replaced locally-carried reusable workflows with caller stubs pinned to the hub, and introduced repo-owned composite hooks for validation (codegen drift guard) and codegen execution.
• Updated the publisher to add a plan gate and moved the NuGet push into a repo-local publish-nuget job that consumes the hub build artifact.
• Swapped coverage tooling from coverlet.MTP to Microsoft.Testing.Extensions.CodeCoverage and refreshed operational/workflow documentation accordingly.

[ptr727]

Answering Qodo's two open findings, which track separately from the review threads.

1. "Smoke build omits ref" (Bug / Correctness). Disproven.

Omitting ref on a smoke call is the contract rather than a gap. Checked against the hub task at the pinned commit a9afa1d:

• build-release-task.yml declares ref as required: false with default: ''. Only branch is required, and both callers here supply it.
• The one use of that input passes it to get-version-task.yml, whose checkout is actions/checkout with ref: ${{ inputs.ref }}. actions/checkout treats an empty ref as unset, resolving to the triggering event's ref, which on a pull_request is the merge ref. So the smoke build versions and packs exactly the tree under review.
• The fleet's reference adoption of this same pattern omits ref on its smoke job too, and supplies it only on the publish job.

publish-release.yml here does pass ref: ${{ github.sha }} on the publish job, because a release must pin the exact commit NBGV versioned rather than a moving ref. Adding it to the smoke job would be actively wrong on a pull_request, where github.sha is the merge commit and pinning it would discard the correct event-ref resolution.

All 18 checks on the reviewed head were green, and that run included the smoke build going through this exact call.

2. "PR title exceeds limit" (Rule violation / Maintainability). Fixed.

The title was 77 characters against the 72-character limit in GOVERNANCE.md "Pull Request Title and Commit Message Conventions". It now reads "Adopt the Hub Reusable Workflows and Relocate the NuGet Push", 60 characters, and the lead commit's subject matches.

🟡 Changes recommended

The new shipped-input path filters omit README.md, but the NuGet package embeds it, so README-only changes won’t trigger smoke/publish and can leave the package readme stale.

🔵 Needs a closer look

The new NuGet publish job only pushes *.nupkg, so the repo’s *.snupkg symbol packages will not be published despite symbols being enabled.

Review details

Suppressed comments (1)

Previously missed (1) — in code that hasn't changed since the last review.

.github/workflows/publish-release.yml:120

• The NuGet publish step only pushes *.nupkg, so the symbol package (*.snupkg) produced by this repo (LanguageTags.csproj sets <IncludeSymbols>true</IncludeSymbols> and SymbolPackageFormat=snupkg) will never be uploaded. This also makes the preceding comment inaccurate: dotnet nuget push does not implicitly upload the co-located .snupkg when you push a .nupkg. Push the .snupkg explicitly (or remove symbol generation).

[ptr727]

Answering the Suppressed comments (1) block from the Copilot review on 015471f, which opens no thread to resolve, and re-answering one Qodo finding that is already fixed.

1. .github/workflows/publish-release.yml:120 — "The NuGet publish step only pushes *.nupkg, so the symbol package (*.snupkg) ... will never be uploaded. This also makes the preceding comment inaccurate: dotnet nuget push does not implicitly upload the co-located .snupkg when you push a .nupkg." Disproven.

The finding is right that this repository produces a .snupkg (LanguageTags.csproj sets IncludeSymbols and SymbolPackageFormat=snupkg) and right that it must reach nuget.org. It is wrong about the mechanism, on two independently checkable points.

The .snupkg is in the artifact. The hub's nuget-build-default/action.yml uploads both patterns into nuget-build-<branch>:

path: | ${{ runner.temp }}/publish/*.nupkg ${{ runner.temp }}/publish/*.snupkg

So after download-artifact into ./nuget, the two files are co-located, which is the precondition the push relies on. (*.nupkg does not glob the .snupkg, since that name ends in .snupkg.)

dotnet nuget push does push a co-located symbol package. That is what its --no-symbols flag exists to suppress: the documented description is "Doesn't push symbols (even if present)", which only means something if the default is to push them. No --no-symbols is passed here.

And this exact mechanism is what has been shipping this package. The build-release-task.yml this PR deletes carried the same command and the same comment, dotnet nuget push .../publish/*.nupkg with no --no-symbols, against a directory holding both files. This PR moves where that step runs, for the OIDC job_workflow_ref reason in the description, and changes nothing about how symbols are pushed. If the claim held, symbol publishing would already have been broken for every release to date rather than newly broken here.

The comment is accurate as written and stays.

2. Qodo, "PR title exceeds limit". Already fixed and reported in a previous comment. The title is now "Adopt the Hub Reusable Workflows and Relocate the NuGet Push", 60 characters against the 72-character limit, and the lead commit subject matches. Qodo appears not to re-evaluate a title change within a run, so the finding stays open on its side with nothing left to do on this one.

[ptr727]

Follow-up now that this has merged and a release has actually run, because two things in this PR could only be proven by a real publish and one of them was a finding I declined.

The publisher was dispatched on develop at run 33592206733. All 12 jobs succeeded, and it produced prerelease 1.5.71-ge44eb09d39.

The relocated OIDC push works. This is the change this PR exists for, and no pull request could exercise it, since a smoke build never reaches a push:

Pushing ***.LanguageTags.1.5.71-ge44eb09d39.nupkg to 'https://www.nuget.org/api/v2/package'...
Created https://www.nuget.org/api/v2/package/ 416ms
Your package was pushed.

No HTTP 401. The job_workflow_ref claim now names this repository's own publish-release.yml, which is what nuget.org validates against the package owner.

The .snupkg finding is settled, and the decline was right. The suppressed finding on publish-release.yml:120 claimed the symbol package "will never be uploaded" and that "dotnet nuget push does not implicitly upload the co-located .snupkg". The same run, same step, immediately after the line above:

Pushing ***.LanguageTags.1.5.71-ge44eb09d39.snupkg to 'https://www.nuget.org/api/v2/symbolpackage'...
Created https://www.nuget.org/api/v2/symbolpackage/ 153ms
Your package was pushed.

One dotnet nuget push ./nuget/*.nupkg invocation, two packages pushed, the symbol one to the symbol server. The comment this PR carries is accurate and no change was owed.

The coverage package swap works.Microsoft.Testing.Extensions.CodeCoverage 18.9.0 under the hub validator's own invocation reported total: 310, failed: 0, succeeded: 310. Worth stating explicitly because the PR description flagged that dotnet test reports "Zero tests ran" on the authoring host: that is confirmed local-only, and it reproduced on a pristine develop checkout there before this change too.

The release-asset rename is confirmed, as the description predicted: the release carries LICENSE, nuget.7z, and README.md, where previous releases carried LanguageTags.7z.

One observation, pre-existing rather than introduced here: the develop prerelease is 1.5.71 while main is at 1.5.90, because NBGV computes git height and develop takes squash merges (one commit each) while main takes merge commits (which bring the whole develop commit list). The previous develop prerelease sat at 1.5.65 against a 1.5.88 main for the same reason. Flagging it rather than treating it as this PR's business.

[ptr727]

Replaces this repository's three local copies of hub-hosted task workflows with caller stubs pinned to the hub at 2.0.539, and reshapes the publisher so the NuGet push runs from this repository rather than from a hub task.

Second of three PRs against audit run 2026-09-02T00:53:04Z | hub a9afa1d. It closes every remaining interface: and hub-only: finding in that run.

Why the push has to move

NuGet.org validates the OIDC token's job_workflow_ref claim against the package owner, so a push running from ptr727/ProjectTemplate's build-release-task.yml is rejected with HTTP 401 (ptr727/ProjectTemplate#1126). The hub task therefore builds and uploads nuget-build-<branch>, and the new publish-nuget job here downloads that artifact and pushes, which is what makes the claim name this repository.

A smoke build never reaches either push, so no pull request can catch this. The first real release is where it would have surfaced.

The dispatch safeguards, verified rather than assumed

main and develop both dispatch, and they cannot cross channels:

• publish-plan-task.yml accepts workflow_dispatch from main or develop only. Any other ref is a hard ::error:: exit, not a silent skip.
• build-release-task.yml's validate-release job runs before any build or push, and refuses a main version carrying a prerelease suffix, or a non-main version lacking one.
• The GitHub release is stamped prerelease: ${{ inputs.branch != 'main' }}.
• version.json already pins publicReleaseRefSpec to ^refs/heads/main$, so NBGV stamps the suffix correctly on both legs.

The push trigger narrows to main, because the plan task's push arm publishes only for main plus a bot actor, so listing develop would be inert.

What changed

• Deletedbuild-release-task.yml, validate-task.yml, and run-codegen-pull-request-task.yml, per the retire dispositions in the hub's spec/divergences.json.
• publish-release.yml gains the required plan job and the needs.validate.result == 'success' gate the audit reported missing, plus publish-nuget.
• merge-bot-pull-request.yml gains the required merge-bot job as a hub stub.
• test-pull-request.yml gains a changes paths-filter job whose entries are the publisher's own shipped-input list, so the smoke gate and the publish gate agree on what affects the package by construction. CODECOV_TOKEN is mapped explicitly rather than inherited, since secrets: inherit on a cross-repository call would hand the hub validator every secret this repository holds.
• Two new hooks the hub tasks call: .github/actions/validate/action.yml carries the codegen-drift guard that used to live in the local validate task, and .github/actions/codegen/action.yml carries the generator invocation.
• Coverage package swapped from coverlet.MTP to Microsoft.Testing.Extensions.CodeCoverage 18.9.0, which is what the hub validator's coverage invocation drives, per WORKFLOW.md D1.6.
• WORKFLOW.md carried whole from the hub, which brings D9.3's set -Eeuo pipefail with it and closesWorkflows and WORKFLOW.md State set -euo pipefail Where the Hub Requires set -Eeuo pipefail #335.
• OPERATIONS.md corrected in three places where it still described the replaced pipeline, and LanguageTags.slnx's GitHub folder refreshed.

Behavior changes worth knowing

• The GitHub release asset is renamed. The deleted local leaf archived to LanguageTags.7z; the hub default archives to nuget.7z and attaches it as release-asset-<branch>-nuget. Nothing in the repo links the old name.
• A develop -> main promotion merge no longer publishes. That is the point of the plan gate, and it closes the auto-publish gap CodeRabbit raised on Promote develop to main #329. Releasing a promotion is now a deliberate dispatch against main.
• A shipped-input merge to develop no longer publishes a prerelease. A develop prerelease is dispatch-only.
• The nuget.org trusted-publishing policy has already been repointed at publish-release.yml by the maintainer, so the first release after this merge is not blocked on it.

Verification

• All 18 CI checks green, which is the real proof: this is the first run in which the hub reusable workflows actually execute for this repository, including the smoke build going through build-release-task.yml by pin and the codegen-drift guard running as the new validate hook.
• dotnet build: 0 warnings, 0 errors. The offline codegen regeneration produces no drift.
• All four workflows pass actionlint; both composite actions parse.
• Repo gate resolved all 7 hub pins against GitHub. eol, eol-coverage, sha-pin clean.
• Full Docker doc-lint set: 6 linters completed. Diff-scoped prose gate: clean.
• A local strict review pass checked each hub call's input, secret, and permission contract against the task definition at the pinned commit, plus the artifact-name match on the OIDC seam and the job gating. It raised 6 findings; four were real prose gaps this change created, fixed before the PR opened.

Review loop

3 rounds across Copilot, CodeRabbit, and Qodo. 5 threads, all resolved.

Fixed:README.md added to both shipped-input lists, after verifying LanguageTags.csproj packs it (PackageReadmeFile plus a Pack="true" item). Without it a README-only bot push to main would not republish, leaving a stale readme on the gallery page, and a README-only PR would skip the smoke build. The PR title was also 77 characters against the 72-character limit and is now 60.

Declined with evidence: that the smoke build omits ref (it is required: false, default: '', and actions/checkout resolves an empty ref to the triggering event's ref, which on a pull_request is the merge ref; the publish job does pass ref: ${{ github.sha }}, where pinning matters). That GOVERNANCE.md should capitalize "Hub" (lowercase is the carried convention, 31 times in the canonical GOVERNANCE.md alone). And that the .snupkg is never pushed, which is answered in the conversation: the hub action uploads *.snupkg alongside *.nupkg into the artifact, dotnet nuget push pushes a co-located symbol package unless --no-symbols is passed, and the deleted local task carried the identical command, so symbol publishing is unchanged rather than newly broken.

Known remaining

Coverage is PARTIAL, 14 of 15 files, and no round names the unread file. The tooling reports that a re-request has never cleared this and routes the decision to the maintainer.

One suppressed finding stays counted on head, the .snupkg one above. It is declined rather than unanswered; a suppressed finding has no resolve API, so it is counted from the round it is raised in regardless of the answer.

High-Level Assessment

The following are alternative approaches to this PR:

1. Keep the release task local

• ➕ Preserves a repository-local OIDC workflow claim
• ➕ Keeps build, release, and NuGet publication in one reusable workflow
• ➖ Continues duplicating fleet release logic
• ➖ Misses centralized hub fixes and contract improvements
• ➖ Requires this repository to maintain versioning and artifact orchestration

2. Use a long-lived NuGet API key

• ➕ Avoids dependency on the OIDC job_workflow_ref claim
• ➕ Could leave publication inside the hub workflow
• ➖ Introduces a persistent high-value secret
• ➖ Weakens least-privilege and credential-rotation posture
• ➖ Conflicts with the fleet trusted-publishing contract

Recommendation: Use the PR's artifact-handoff design. It centralizes reusable planning, validation, and build behavior while keeping only the identity-sensitive NuGet push local, preserving OIDC trusted publishing and tightly scoping id-token permission. Keeping the entire release task local would solve the claim issue but retain substantial duplicated infrastructure; an API key would solve it at an unacceptable security cost.

• Adds a composite action invoked by the hub codegen task. It retains only the repository-specific generator command while the hub owns checkout, SDK setup, formatting, credentials, and pull-request creation.

.github/actions/codegen/action.yml

action.ymlAdd deterministic codegen drift validation hook+44/-0

Add deterministic codegen drift validation hook

• Adds the repository hook used by the hub validator to regenerate committed data offline, apply CSharpier formatting, and fail on tracked or untracked drift. The check avoids upstream network access and reports concise status and diff statistics.

merge-bot-pull-request.ymlReplace local merge-bot logic with a pinned hub caller+13/-120

Replace local merge-bot logic with a pinned hub caller

• Reduces the workflow to a least-privilege caller of the hub merge-bot task pinned at 2.0.539. It preserves pull-request-target triggering, per-PR concurrency, and explicitly maps the GitHub App credentials.

.github/workflows/merge-bot-pull-request.yml

run-periodic-codegen-pull-request.ymlDelegate scheduled code generation to the hub task+14/-10

Delegate scheduled code generation to the hub task

• Switches the periodic codegen entry workflow from a local reusable workflow to the pinned hub implementation. It removes default token permissions and explicitly passes only the required GitHub App credentials.

.github/workflows/run-periodic-codegen-pull-request.yml

test-pull-request.ymlAdopt hub CI tasks and target-aware smoke builds+74/-28

Adopt hub CI tasks and target-aware smoke builds

• Changes CI to run for pull requests and merged results on main and develop, and adds a shipped-input paths filter for NuGet smoke builds. Validation and release smoke work now call pinned hub workflows with explicit secrets and permissions, while the aggregator accepts intentionally skipped smoke jobs but still blocks failures and cancellations.

.github/workflows/test-pull-request.yml

Directory.Packages.propsReplace Coverlet MTP with Microsoft coverage tooling+6/-3

Replace Coverlet MTP with Microsoft coverage tooling

• Replaces coverlet.MTP with Microsoft.Testing.Extensions.CodeCoverage 18.9.0. The documented minimum avoids incompatible Microsoft.Testing.Platform 1.x assemblies that can execute zero tests while producing misleading coverage output.

Directory.Packages.props

LanguageTags.slnxRefresh workflow and action files in the solution+5/-2

Refresh workflow and action files in the solution

• Adds the new codegen and validation hooks and current entry workflows to the GitHub solution folder. It removes stale workflow names that no longer represent the repository layout.

LanguageTags.slnx

LanguageTagsTests.csprojUse Microsoft Testing Platform coverage extension+4/-8

Use Microsoft Testing Platform coverage extension

• Replaces the coverlet.MTP reference with Microsoft.Testing.Extensions.CodeCoverage. The package remains available on the test project's compile-time closure so its native MTP registration code can compile.

The new smoke-build call does not pass the required ref input to build-release-task.yml, so
target-changing pull requests cannot successfully invoke the reusable build. The required aggregator

🔵 Needs a closer look

It substantially changes release/publish workflow behavior (including OIDC NuGet publishing seams) in ways that are difficult to fully validate without end-to-end release execution.

Pull request overview

This PR adopts the hub’s reusable GitHub Actions workflows (pinned to 2.0.539) and reshapes the release pipeline so the NuGet push executes in this repository’s workflow context (to satisfy NuGet.org OIDC job_workflow_ref validation). It also updates the repo’s workflow/runbook documentation and aligns test coverage tooling with the hub validator.

Changes:

• Replaced locally-carried reusable workflows with caller stubs pinned to the hub, and introduced repo-owned composite hooks for validation (codegen drift guard) and codegen execution.
• Updated the publisher to add a plan gate and moved the NuGet push into a repo-local publish-nuget job that consumes the hub build artifact.
• Swapped coverage tooling from coverlet.MTP to Microsoft.Testing.Extensions.CodeCoverage and refreshed operational/workflow documentation accordingly.

[ptr727]

Answering Qodo's two open findings, which track separately from the review threads.

1. "Smoke build omits ref" (Bug / Correctness). Disproven.

Omitting ref on a smoke call is the contract rather than a gap. Checked against the hub task at the pinned commit a9afa1d:

• build-release-task.yml declares ref as required: false with default: ''. Only branch is required, and both callers here supply it.
• The one use of that input passes it to get-version-task.yml, whose checkout is actions/checkout with ref: ${{ inputs.ref }}. actions/checkout treats an empty ref as unset, resolving to the triggering event's ref, which on a pull_request is the merge ref. So the smoke build versions and packs exactly the tree under review.
• The fleet's reference adoption of this same pattern omits ref on its smoke job too, and supplies it only on the publish job.

publish-release.yml here does pass ref: ${{ github.sha }} on the publish job, because a release must pin the exact commit NBGV versioned rather than a moving ref. Adding it to the smoke job would be actively wrong on a pull_request, where github.sha is the merge commit and pinning it would discard the correct event-ref resolution.

All 18 checks on the reviewed head were green, and that run included the smoke build going through this exact call.

2. "PR title exceeds limit" (Rule violation / Maintainability). Fixed.

The title was 77 characters against the 72-character limit in GOVERNANCE.md "Pull Request Title and Commit Message Conventions". It now reads "Adopt the Hub Reusable Workflows and Relocate the NuGet Push", 60 characters, and the lead commit's subject matches.

🟡 Changes recommended

The new shipped-input path filters omit README.md, but the NuGet package embeds it, so README-only changes won’t trigger smoke/publish and can leave the package readme stale.

🔵 Needs a closer look

The new NuGet publish job only pushes *.nupkg, so the repo’s *.snupkg symbol packages will not be published despite symbols being enabled.

Review details

Suppressed comments (1)

Previously missed (1) — in code that hasn't changed since the last review.

.github/workflows/publish-release.yml:120

• The NuGet publish step only pushes *.nupkg, so the symbol package (*.snupkg) produced by this repo (LanguageTags.csproj sets <IncludeSymbols>true</IncludeSymbols> and SymbolPackageFormat=snupkg) will never be uploaded. This also makes the preceding comment inaccurate: dotnet nuget push does not implicitly upload the co-located .snupkg when you push a .nupkg. Push the .snupkg explicitly (or remove symbol generation).

[ptr727]

Answering the Suppressed comments (1) block from the Copilot review on 015471f, which opens no thread to resolve, and re-answering one Qodo finding that is already fixed.

1. .github/workflows/publish-release.yml:120 — "The NuGet publish step only pushes *.nupkg, so the symbol package (*.snupkg) ... will never be uploaded. This also makes the preceding comment inaccurate: dotnet nuget push does not implicitly upload the co-located .snupkg when you push a .nupkg." Disproven.

The finding is right that this repository produces a .snupkg (LanguageTags.csproj sets IncludeSymbols and SymbolPackageFormat=snupkg) and right that it must reach nuget.org. It is wrong about the mechanism, on two independently checkable points.

The .snupkg is in the artifact. The hub's nuget-build-default/action.yml uploads both patterns into nuget-build-<branch>:

path: | ${{ runner.temp }}/publish/*.nupkg ${{ runner.temp }}/publish/*.snupkg

So after download-artifact into ./nuget, the two files are co-located, which is the precondition the push relies on. (*.nupkg does not glob the .snupkg, since that name ends in .snupkg.)

dotnet nuget push does push a co-located symbol package. That is what its --no-symbols flag exists to suppress: the documented description is "Doesn't push symbols (even if present)", which only means something if the default is to push them. No --no-symbols is passed here.

And this exact mechanism is what has been shipping this package. The build-release-task.yml this PR deletes carried the same command and the same comment, dotnet nuget push .../publish/*.nupkg with no --no-symbols, against a directory holding both files. This PR moves where that step runs, for the OIDC job_workflow_ref reason in the description, and changes nothing about how symbols are pushed. If the claim held, symbol publishing would already have been broken for every release to date rather than newly broken here.

The comment is accurate as written and stays.

2. Qodo, "PR title exceeds limit". Already fixed and reported in a previous comment. The title is now "Adopt the Hub Reusable Workflows and Relocate the NuGet Push", 60 characters against the 72-character limit, and the lead commit subject matches. Qodo appears not to re-evaluate a title change within a run, so the finding stays open on its side with nothing left to do on this one.

[ptr727]

Follow-up now that this has merged and a release has actually run, because two things in this PR could only be proven by a real publish and one of them was a finding I declined.

The publisher was dispatched on develop at run 33592206733. All 12 jobs succeeded, and it produced prerelease 1.5.71-ge44eb09d39.

The relocated OIDC push works. This is the change this PR exists for, and no pull request could exercise it, since a smoke build never reaches a push:

Pushing ***.LanguageTags.1.5.71-ge44eb09d39.nupkg to 'https://www.nuget.org/api/v2/package'...
Created https://www.nuget.org/api/v2/package/ 416ms
Your package was pushed.

No HTTP 401. The job_workflow_ref claim now names this repository's own publish-release.yml, which is what nuget.org validates against the package owner.

The .snupkg finding is settled, and the decline was right. The suppressed finding on publish-release.yml:120 claimed the symbol package "will never be uploaded" and that "dotnet nuget push does not implicitly upload the co-located .snupkg". The same run, same step, immediately after the line above:

Pushing ***.LanguageTags.1.5.71-ge44eb09d39.snupkg to 'https://www.nuget.org/api/v2/symbolpackage'...
Created https://www.nuget.org/api/v2/symbolpackage/ 153ms
Your package was pushed.

One dotnet nuget push ./nuget/*.nupkg invocation, two packages pushed, the symbol one to the symbol server. The comment this PR carries is accurate and no change was owed.

The coverage package swap works.Microsoft.Testing.Extensions.CodeCoverage 18.9.0 under the hub validator's own invocation reported total: 310, failed: 0, succeeded: 310. Worth stating explicitly because the PR description flagged that dotnet test reports "Zero tests ran" on the authoring host: that is confirmed local-only, and it reproduced on a pristine develop checkout there before this change too.

The release-asset rename is confirmed, as the description predicted: the release carries LICENSE, nuget.7z, and README.md, where previous releases carried LanguageTags.7z.

One observation, pre-existing rather than introduced here: the develop prerelease is 1.5.71 while main is at 1.5.90, because NBGV computes git height and develop takes squash merges (one commit each) while main takes merge commits (which bring the whole develop commit list). The previous develop prerelease sat at 1.5.65 against a 1.5.88 main for the same reason. Flagging it rather than treating it as this PR's business.

[ptr727]

Replaces this repository's three local copies of hub-hosted task workflows with caller stubs pinned to the hub at 2.0.539, and reshapes the publisher so the NuGet push runs from this repository rather than from a hub task.

Second of three PRs against audit run 2026-09-02T00:53:04Z | hub a9afa1d. It closes every remaining interface: and hub-only: finding in that run.

Why the push has to move

NuGet.org validates the OIDC token's job_workflow_ref claim against the package owner, so a push running from ptr727/ProjectTemplate's build-release-task.yml is rejected with HTTP 401 (ptr727/ProjectTemplate#1126). The hub task therefore builds and uploads nuget-build-<branch>, and the new publish-nuget job here downloads that artifact and pushes, which is what makes the claim name this repository.

A smoke build never reaches either push, so no pull request can catch this. The first real release is where it would have surfaced.

The dispatch safeguards, verified rather than assumed

main and develop both dispatch, and they cannot cross channels:

• publish-plan-task.yml accepts workflow_dispatch from main or develop only. Any other ref is a hard ::error:: exit, not a silent skip.
• build-release-task.yml's validate-release job runs before any build or push, and refuses a main version carrying a prerelease suffix, or a non-main version lacking one.
• The GitHub release is stamped prerelease: ${{ inputs.branch != 'main' }}.
• version.json already pins publicReleaseRefSpec to ^refs/heads/main$, so NBGV stamps the suffix correctly on both legs.

The push trigger narrows to main, because the plan task's push arm publishes only for main plus a bot actor, so listing develop would be inert.

What changed

• Deletedbuild-release-task.yml, validate-task.yml, and run-codegen-pull-request-task.yml, per the retire dispositions in the hub's spec/divergences.json.
• publish-release.yml gains the required plan job and the needs.validate.result == 'success' gate the audit reported missing, plus publish-nuget.
• merge-bot-pull-request.yml gains the required merge-bot job as a hub stub.
• test-pull-request.yml gains a changes paths-filter job whose entries are the publisher's own shipped-input list, so the smoke gate and the publish gate agree on what affects the package by construction. CODECOV_TOKEN is mapped explicitly rather than inherited, since secrets: inherit on a cross-repository call would hand the hub validator every secret this repository holds.
• Two new hooks the hub tasks call: .github/actions/validate/action.yml carries the codegen-drift guard that used to live in the local validate task, and .github/actions/codegen/action.yml carries the generator invocation.
• Coverage package swapped from coverlet.MTP to Microsoft.Testing.Extensions.CodeCoverage 18.9.0, which is what the hub validator's coverage invocation drives, per WORKFLOW.md D1.6.
• WORKFLOW.md carried whole from the hub, which brings D9.3's set -Eeuo pipefail with it and closesWorkflows and WORKFLOW.md State set -euo pipefail Where the Hub Requires set -Eeuo pipefail #335.
• OPERATIONS.md corrected in three places where it still described the replaced pipeline, and LanguageTags.slnx's GitHub folder refreshed.

Behavior changes worth knowing

• The GitHub release asset is renamed. The deleted local leaf archived to LanguageTags.7z; the hub default archives to nuget.7z and attaches it as release-asset-<branch>-nuget. Nothing in the repo links the old name.
• A develop -> main promotion merge no longer publishes. That is the point of the plan gate, and it closes the auto-publish gap CodeRabbit raised on Promote develop to main #329. Releasing a promotion is now a deliberate dispatch against main.
• A shipped-input merge to develop no longer publishes a prerelease. A develop prerelease is dispatch-only.
• The nuget.org trusted-publishing policy has already been repointed at publish-release.yml by the maintainer, so the first release after this merge is not blocked on it.

Verification

• All 18 CI checks green, which is the real proof: this is the first run in which the hub reusable workflows actually execute for this repository, including the smoke build going through build-release-task.yml by pin and the codegen-drift guard running as the new validate hook.
• dotnet build: 0 warnings, 0 errors. The offline codegen regeneration produces no drift.
• All four workflows pass actionlint; both composite actions parse.
• Repo gate resolved all 7 hub pins against GitHub. eol, eol-coverage, sha-pin clean.
• Full Docker doc-lint set: 6 linters completed. Diff-scoped prose gate: clean.
• A local strict review pass checked each hub call's input, secret, and permission contract against the task definition at the pinned commit, plus the artifact-name match on the OIDC seam and the job gating. It raised 6 findings; four were real prose gaps this change created, fixed before the PR opened.

Review loop

3 rounds across Copilot, CodeRabbit, and Qodo. 5 threads, all resolved.

Fixed:README.md added to both shipped-input lists, after verifying LanguageTags.csproj packs it (PackageReadmeFile plus a Pack="true" item). Without it a README-only bot push to main would not republish, leaving a stale readme on the gallery page, and a README-only PR would skip the smoke build. The PR title was also 77 characters against the 72-character limit and is now 60.

Declined with evidence: that the smoke build omits ref (it is required: false, default: '', and actions/checkout resolves an empty ref to the triggering event's ref, which on a pull_request is the merge ref; the publish job does pass ref: ${{ github.sha }}, where pinning matters). That GOVERNANCE.md should capitalize "Hub" (lowercase is the carried convention, 31 times in the canonical GOVERNANCE.md alone). And that the .snupkg is never pushed, which is answered in the conversation: the hub action uploads *.snupkg alongside *.nupkg into the artifact, dotnet nuget push pushes a co-located symbol package unless --no-symbols is passed, and the deleted local task carried the identical command, so symbol publishing is unchanged rather than newly broken.

Known remaining

Coverage is PARTIAL, 14 of 15 files, and no round names the unread file. The tooling reports that a re-request has never cleared this and routes the decision to the maintainer.

One suppressed finding stays counted on head, the .snupkg one above. It is declined rather than unanswered; a suppressed finding has no resolve API, so it is counted from the round it is raised in regardless of the answer.

High-Level Assessment

The following are alternative approaches to this PR:

1. Keep the release task local

• ➕ Preserves a repository-local OIDC workflow claim
• ➕ Keeps build, release, and NuGet publication in one reusable workflow
• ➖ Continues duplicating fleet release logic
• ➖ Misses centralized hub fixes and contract improvements
• ➖ Requires this repository to maintain versioning and artifact orchestration

2. Use a long-lived NuGet API key

• ➕ Avoids dependency on the OIDC job_workflow_ref claim
• ➕ Could leave publication inside the hub workflow
• ➖ Introduces a persistent high-value secret
• ➖ Weakens least-privilege and credential-rotation posture
• ➖ Conflicts with the fleet trusted-publishing contract

Recommendation: Use the PR's artifact-handoff design. It centralizes reusable planning, validation, and build behavior while keeping only the identity-sensitive NuGet push local, preserving OIDC trusted publishing and tightly scoping id-token permission. Keeping the entire release task local would solve the claim issue but retain substantial duplicated infrastructure; an API key would solve it at an unacceptable security cost.

🔵 Needs a closer look

It substantially changes release/publish workflow behavior (including OIDC NuGet publishing seams) in ways that are difficult to fully validate without end-to-end release execution.

Pull request overview

This PR adopts the hub’s reusable GitHub Actions workflows (pinned to 2.0.539) and reshapes the release pipeline so the NuGet push executes in this repository’s workflow context (to satisfy NuGet.org OIDC job_workflow_ref validation). It also updates the repo’s workflow/runbook documentation and aligns test coverage tooling with the hub validator.

Changes:

• Replaced locally-carried reusable workflows with caller stubs pinned to the hub, and introduced repo-owned composite hooks for validation (codegen drift guard) and codegen execution.
• Updated the publisher to add a plan gate and moved the NuGet push into a repo-local publish-nuget job that consumes the hub build artifact.
• Swapped coverage tooling from coverlet.MTP to Microsoft.Testing.Extensions.CodeCoverage and refreshed operational/workflow documentation accordingly.

File summaries

File	Description
WORKFLOW.md	Replaced prior workflow contract text with the hub-aligned contract and updated conventions (notably set -Eeuo pipefail) and seam model.

[ptr727]

Answering Qodo's two open findings, which track separately from the review threads.

1. "Smoke build omits ref" (Bug / Correctness). Disproven.

Omitting ref on a smoke call is the contract rather than a gap. Checked against the hub task at the pinned commit a9afa1d:

• build-release-task.yml declares ref as required: false with default: ''. Only branch is required, and both callers here supply it.
• The one use of that input passes it to get-version-task.yml, whose checkout is actions/checkout with ref: ${{ inputs.ref }}. actions/checkout treats an empty ref as unset, resolving to the triggering event's ref, which on a pull_request is the merge ref. So the smoke build versions and packs exactly the tree under review.
• The fleet's reference adoption of this same pattern omits ref on its smoke job too, and supplies it only on the publish job.

publish-release.yml here does pass ref: ${{ github.sha }} on the publish job, because a release must pin the exact commit NBGV versioned rather than a moving ref. Adding it to the smoke job would be actively wrong on a pull_request, where github.sha is the merge commit and pinning it would discard the correct event-ref resolution.

All 18 checks on the reviewed head were green, and that run included the smoke build going through this exact call.

2. "PR title exceeds limit" (Rule violation / Maintainability). Fixed.

The title was 77 characters against the 72-character limit in GOVERNANCE.md "Pull Request Title and Commit Message Conventions". It now reads "Adopt the Hub Reusable Workflows and Relocate the NuGet Push", 60 characters, and the lead commit's subject matches.

🟡 Changes recommended

The new shipped-input path filters omit README.md, but the NuGet package embeds it, so README-only changes won’t trigger smoke/publish and can leave the package readme stale.

The new NuGet publish job only pushes *.nupkg, so the repo’s *.snupkg symbol packages will not be published despite symbols being enabled.

Review details

Suppressed comments (1)

Previously missed (1) — in code that hasn't changed since the last review.

.github/workflows/publish-release.yml:120

• The NuGet publish step only pushes *.nupkg, so the symbol package (*.snupkg) produced by this repo (LanguageTags.csproj sets <IncludeSymbols>true</IncludeSymbols> and SymbolPackageFormat=snupkg) will never be uploaded. This also makes the preceding comment inaccurate: dotnet nuget push does not implicitly upload the co-located .snupkg when you push a .nupkg. Push the .snupkg explicitly (or remove symbol generation).

[ptr727]

Answering the Suppressed comments (1) block from the Copilot review on 015471f, which opens no thread to resolve, and re-answering one Qodo finding that is already fixed.

1. .github/workflows/publish-release.yml:120 — "The NuGet publish step only pushes *.nupkg, so the symbol package (*.snupkg) ... will never be uploaded. This also makes the preceding comment inaccurate: dotnet nuget push does not implicitly upload the co-located .snupkg when you push a .nupkg." Disproven.

The finding is right that this repository produces a .snupkg (LanguageTags.csproj sets IncludeSymbols and SymbolPackageFormat=snupkg) and right that it must reach nuget.org. It is wrong about the mechanism, on two independently checkable points.

The .snupkg is in the artifact. The hub's nuget-build-default/action.yml uploads both patterns into nuget-build-<branch>:

path: | ${{ runner.temp }}/publish/*.nupkg ${{ runner.temp }}/publish/*.snupkg

So after download-artifact into ./nuget, the two files are co-located, which is the precondition the push relies on. (*.nupkg does not glob the .snupkg, since that name ends in .snupkg.)

dotnet nuget push does push a co-located symbol package. That is what its --no-symbols flag exists to suppress: the documented description is "Doesn't push symbols (even if present)", which only means something if the default is to push them. No --no-symbols is passed here.

And this exact mechanism is what has been shipping this package. The build-release-task.yml this PR deletes carried the same command and the same comment, dotnet nuget push .../publish/*.nupkg with no --no-symbols, against a directory holding both files. This PR moves where that step runs, for the OIDC job_workflow_ref reason in the description, and changes nothing about how symbols are pushed. If the claim held, symbol publishing would already have been broken for every release to date rather than newly broken here.

The comment is accurate as written and stays.

2. Qodo, "PR title exceeds limit". Already fixed and reported in a previous comment. The title is now "Adopt the Hub Reusable Workflows and Relocate the NuGet Push", 60 characters against the 72-character limit, and the lead commit subject matches. Qodo appears not to re-evaluate a title change within a run, so the finding stays open on its side with nothing left to do on this one.

[ptr727]

Follow-up now that this has merged and a release has actually run, because two things in this PR could only be proven by a real publish and one of them was a finding I declined.

The publisher was dispatched on develop at run 33592206733. All 12 jobs succeeded, and it produced prerelease 1.5.71-ge44eb09d39.

The relocated OIDC push works. This is the change this PR exists for, and no pull request could exercise it, since a smoke build never reaches a push:

Pushing ***.LanguageTags.1.5.71-ge44eb09d39.nupkg to 'https://www.nuget.org/api/v2/package'...
Created https://www.nuget.org/api/v2/package/ 416ms
Your package was pushed.

No HTTP 401. The job_workflow_ref claim now names this repository's own publish-release.yml, which is what nuget.org validates against the package owner.

The .snupkg finding is settled, and the decline was right. The suppressed finding on publish-release.yml:120 claimed the symbol package "will never be uploaded" and that "dotnet nuget push does not implicitly upload the co-located .snupkg". The same run, same step, immediately after the line above:

Pushing ***.LanguageTags.1.5.71-ge44eb09d39.snupkg to 'https://www.nuget.org/api/v2/symbolpackage'...
Created https://www.nuget.org/api/v2/symbolpackage/ 153ms
Your package was pushed.

One dotnet nuget push ./nuget/*.nupkg invocation, two packages pushed, the symbol one to the symbol server. The comment this PR carries is accurate and no change was owed.

The coverage package swap works.Microsoft.Testing.Extensions.CodeCoverage 18.9.0 under the hub validator's own invocation reported total: 310, failed: 0, succeeded: 310. Worth stating explicitly because the PR description flagged that dotnet test reports "Zero tests ran" on the authoring host: that is confirmed local-only, and it reproduced on a pristine develop checkout there before this change too.

The release-asset rename is confirmed, as the description predicted: the release carries LICENSE, nuget.7z, and README.md, where previous releases carried LanguageTags.7z.

One observation, pre-existing rather than introduced here: the develop prerelease is 1.5.71 while main is at 1.5.90, because NBGV computes git height and develop takes squash merges (one commit each) while main takes merge commits (which bring the whole develop commit list). The previous develop prerelease sat at 1.5.65 against a 1.5.88 main for the same reason. Flagging it rather than treating it as this PR's business.

[ptr727]

Replaces this repository's three local copies of hub-hosted task workflows with caller stubs pinned to the hub at 2.0.539, and reshapes the publisher so the NuGet push runs from this repository rather than from a hub task.

Second of three PRs against audit run 2026-09-02T00:53:04Z | hub a9afa1d. It closes every remaining interface: and hub-only: finding in that run.

Why the push has to move

NuGet.org validates the OIDC token's job_workflow_ref claim against the package owner, so a push running from ptr727/ProjectTemplate's build-release-task.yml is rejected with HTTP 401 (ptr727/ProjectTemplate#1126). The hub task therefore builds and uploads nuget-build-<branch>, and the new publish-nuget job here downloads that artifact and pushes, which is what makes the claim name this repository.

A smoke build never reaches either push, so no pull request can catch this. The first real release is where it would have surfaced.

The dispatch safeguards, verified rather than assumed

main and develop both dispatch, and they cannot cross channels:

• publish-plan-task.yml accepts workflow_dispatch from main or develop only. Any other ref is a hard ::error:: exit, not a silent skip.
• build-release-task.yml's validate-release job runs before any build or push, and refuses a main version carrying a prerelease suffix, or a non-main version lacking one.
• The GitHub release is stamped prerelease: ${{ inputs.branch != 'main' }}.
• version.json already pins publicReleaseRefSpec to ^refs/heads/main$, so NBGV stamps the suffix correctly on both legs.

The push trigger narrows to main, because the plan task's push arm publishes only for main plus a bot actor, so listing develop would be inert.

What changed

• Deletedbuild-release-task.yml, validate-task.yml, and run-codegen-pull-request-task.yml, per the retire dispositions in the hub's spec/divergences.json.
• publish-release.yml gains the required plan job and the needs.validate.result == 'success' gate the audit reported missing, plus publish-nuget.
• merge-bot-pull-request.yml gains the required merge-bot job as a hub stub.
• test-pull-request.yml gains a changes paths-filter job whose entries are the publisher's own shipped-input list, so the smoke gate and the publish gate agree on what affects the package by construction. CODECOV_TOKEN is mapped explicitly rather than inherited, since secrets: inherit on a cross-repository call would hand the hub validator every secret this repository holds.
• Two new hooks the hub tasks call: .github/actions/validate/action.yml carries the codegen-drift guard that used to live in the local validate task, and .github/actions/codegen/action.yml carries the generator invocation.
• Coverage package swapped from coverlet.MTP to Microsoft.Testing.Extensions.CodeCoverage 18.9.0, which is what the hub validator's coverage invocation drives, per WORKFLOW.md D1.6.
• WORKFLOW.md carried whole from the hub, which brings D9.3's set -Eeuo pipefail with it and closesWorkflows and WORKFLOW.md State set -euo pipefail Where the Hub Requires set -Eeuo pipefail #335.
• OPERATIONS.md corrected in three places where it still described the replaced pipeline, and LanguageTags.slnx's GitHub folder refreshed.

Behavior changes worth knowing

• The GitHub release asset is renamed. The deleted local leaf archived to LanguageTags.7z; the hub default archives to nuget.7z and attaches it as release-asset-<branch>-nuget. Nothing in the repo links the old name.
• A develop -> main promotion merge no longer publishes. That is the point of the plan gate, and it closes the auto-publish gap CodeRabbit raised on Promote develop to main #329. Releasing a promotion is now a deliberate dispatch against main.
• A shipped-input merge to develop no longer publishes a prerelease. A develop prerelease is dispatch-only.
• The nuget.org trusted-publishing policy has already been repointed at publish-release.yml by the maintainer, so the first release after this merge is not blocked on it.

Verification

• All 18 CI checks green, which is the real proof: this is the first run in which the hub reusable workflows actually execute for this repository, including the smoke build going through build-release-task.yml by pin and the codegen-drift guard running as the new validate hook.
• dotnet build: 0 warnings, 0 errors. The offline codegen regeneration produces no drift.
• All four workflows pass actionlint; both composite actions parse.
• Repo gate resolved all 7 hub pins against GitHub. eol, eol-coverage, sha-pin clean.
• Full Docker doc-lint set: 6 linters completed. Diff-scoped prose gate: clean.
• A local strict review pass checked each hub call's input, secret, and permission contract against the task definition at the pinned commit, plus the artifact-name match on the OIDC seam and the job gating. It raised 6 findings; four were real prose gaps this change created, fixed before the PR opened.

Review loop

3 rounds across Copilot, CodeRabbit, and Qodo. 5 threads, all resolved.

Fixed:README.md added to both shipped-input lists, after verifying LanguageTags.csproj packs it (PackageReadmeFile plus a Pack="true" item). Without it a README-only bot push to main would not republish, leaving a stale readme on the gallery page, and a README-only PR would skip the smoke build. The PR title was also 77 characters against the 72-character limit and is now 60.

Declined with evidence: that the smoke build omits ref (it is required: false, default: '', and actions/checkout resolves an empty ref to the triggering event's ref, which on a pull_request is the merge ref; the publish job does pass ref: ${{ github.sha }}, where pinning matters). That GOVERNANCE.md should capitalize "Hub" (lowercase is the carried convention, 31 times in the canonical GOVERNANCE.md alone). And that the .snupkg is never pushed, which is answered in the conversation: the hub action uploads *.snupkg alongside *.nupkg into the artifact, dotnet nuget push pushes a co-located symbol package unless --no-symbols is passed, and the deleted local task carried the identical command, so symbol publishing is unchanged rather than newly broken.

Known remaining

Coverage is PARTIAL, 14 of 15 files, and no round names the unread file. The tooling reports that a re-request has never cleared this and routes the decision to the maintainer.

One suppressed finding stays counted on head, the .snupkg one above. It is declined rather than unanswered; a suppressed finding has no resolve API, so it is counted from the round it is raised in regardless of the answer.

High-Level Assessment

The following are alternative approaches to this PR:

1. Keep the release task local

• ➕ Preserves a repository-local OIDC workflow claim
• ➕ Keeps build, release, and NuGet publication in one reusable workflow
• ➖ Continues duplicating fleet release logic
• ➖ Misses centralized hub fixes and contract improvements
• ➖ Requires this repository to maintain versioning and artifact orchestration

2. Use a long-lived NuGet API key

• ➕ Avoids dependency on the OIDC job_workflow_ref claim
• ➕ Could leave publication inside the hub workflow
• ➖ Introduces a persistent high-value secret
• ➖ Weakens least-privilege and credential-rotation posture
• ➖ Conflicts with the fleet trusted-publishing contract

Recommendation: Use the PR's artifact-handoff design. It centralizes reusable planning, validation, and build behavior while keeping only the identity-sensitive NuGet push local, preserving OIDC trusted publishing and tightly scoping id-token permission. Keeping the entire release task local would solve the claim issue but retain substantial duplicated infrastructure; an API key would solve it at an unacceptable security cost.

🔵 Needs a closer look

It substantially changes release/publish workflow behavior (including OIDC NuGet publishing seams) in ways that are difficult to fully validate without end-to-end release execution.

Pull request overview

This PR adopts the hub’s reusable GitHub Actions workflows (pinned to 2.0.539) and reshapes the release pipeline so the NuGet push executes in this repository’s workflow context (to satisfy NuGet.org OIDC job_workflow_ref validation). It also updates the repo’s workflow/runbook documentation and aligns test coverage tooling with the hub validator.

Changes:

• Replaced locally-carried reusable workflows with caller stubs pinned to the hub, and introduced repo-owned composite hooks for validation (codegen drift guard) and codegen execution.
• Updated the publisher to add a plan gate and moved the NuGet push into a repo-local publish-nuget job that consumes the hub build artifact.
• Swapped coverage tooling from coverlet.MTP to Microsoft.Testing.Extensions.CodeCoverage and refreshed operational/workflow documentation accordingly.

File summaries

[ptr727]

Answering Qodo's two open findings, which track separately from the review threads.

1. "Smoke build omits ref" (Bug / Correctness). Disproven.

Omitting ref on a smoke call is the contract rather than a gap. Checked against the hub task at the pinned commit a9afa1d:

• build-release-task.yml declares ref as required: false with default: ''. Only branch is required, and both callers here supply it.
• The one use of that input passes it to get-version-task.yml, whose checkout is actions/checkout with ref: ${{ inputs.ref }}. actions/checkout treats an empty ref as unset, resolving to the triggering event's ref, which on a pull_request is the merge ref. So the smoke build versions and packs exactly the tree under review.
• The fleet's reference adoption of this same pattern omits ref on its smoke job too, and supplies it only on the publish job.

publish-release.yml here does pass ref: ${{ github.sha }} on the publish job, because a release must pin the exact commit NBGV versioned rather than a moving ref. Adding it to the smoke job would be actively wrong on a pull_request, where github.sha is the merge commit and pinning it would discard the correct event-ref resolution.

All 18 checks on the reviewed head were green, and that run included the smoke build going through this exact call.

2. "PR title exceeds limit" (Rule violation / Maintainability). Fixed.

The title was 77 characters against the 72-character limit in GOVERNANCE.md "Pull Request Title and Commit Message Conventions". It now reads "Adopt the Hub Reusable Workflows and Relocate the NuGet Push", 60 characters, and the lead commit's subject matches.

The new shipped-input path filters omit README.md, but the NuGet package embeds it, so README-only changes won’t trigger smoke/publish and can leave the package readme stale.

Once you've addressed the issues Copilot identified, you can request another Copilot review.

🔵 Needs a closer look

The new NuGet publish job only pushes *.nupkg, so the repo’s *.snupkg symbol packages will not be published despite symbols being enabled.

Review details

Suppressed comments (1)

Previously missed (1) — in code that hasn't changed since the last review.

.github/workflows/publish-release.yml:120

• The NuGet publish step only pushes *.nupkg, so the symbol package (*.snupkg) produced by this repo (LanguageTags.csproj sets <IncludeSymbols>true</IncludeSymbols> and SymbolPackageFormat=snupkg) will never be uploaded. This also makes the preceding comment inaccurate: dotnet nuget push does not implicitly upload the co-located .snupkg when you push a .nupkg. Push the .snupkg explicitly (or remove symbol generation).

Answering the Suppressed comments (1) block from the Copilot review on 015471f, which opens no thread to resolve, and re-answering one Qodo finding that is already fixed.

1. .github/workflows/publish-release.yml:120 — "The NuGet publish step only pushes *.nupkg, so the symbol package (*.snupkg) ... will never be uploaded. This also makes the preceding comment inaccurate: dotnet nuget push does not implicitly upload the co-located .snupkg when you push a .nupkg." Disproven.

The finding is right that this repository produces a .snupkg (LanguageTags.csproj sets IncludeSymbols and SymbolPackageFormat=snupkg) and right that it must reach nuget.org. It is wrong about the mechanism, on two independently checkable points.

The .snupkg is in the artifact. The hub's nuget-build-default/action.yml uploads both patterns into nuget-build-<branch>:

path: | ${{ runner.temp }}/publish/*.nupkg ${{ runner.temp }}/publish/*.snupkg

So after download-artifact into ./nuget, the two files are co-located, which is the precondition the push relies on. (*.nupkg does not glob the .snupkg, since that name ends in .snupkg.)

dotnet nuget push does push a co-located symbol package. That is what its --no-symbols flag exists to suppress: the documented description is "Doesn't push symbols (even if present)", which only means something if the default is to push them. No --no-symbols is passed here.

And this exact mechanism is what has been shipping this package. The build-release-task.yml this PR deletes carried the same command and the same comment, dotnet nuget push .../publish/*.nupkg with no --no-symbols, against a directory holding both files. This PR moves where that step runs, for the OIDC job_workflow_ref reason in the description, and changes nothing about how symbols are pushed. If the claim held, symbol publishing would already have been broken for every release to date rather than newly broken here.

The comment is accurate as written and stays.

2. Qodo, "PR title exceeds limit". Already fixed and reported in a previous comment. The title is now "Adopt the Hub Reusable Workflows and Relocate the NuGet Push", 60 characters against the 72-character limit, and the lead commit subject matches. Qodo appears not to re-evaluate a title change within a run, so the finding stays open on its side with nothing left to do on this one.

[ptr727]

Follow-up now that this has merged and a release has actually run, because two things in this PR could only be proven by a real publish and one of them was a finding I declined.

The publisher was dispatched on develop at run 33592206733. All 12 jobs succeeded, and it produced prerelease 1.5.71-ge44eb09d39.

The relocated OIDC push works. This is the change this PR exists for, and no pull request could exercise it, since a smoke build never reaches a push:

Pushing ***.LanguageTags.1.5.71-ge44eb09d39.nupkg to 'https://www.nuget.org/api/v2/package'...
Created https://www.nuget.org/api/v2/package/ 416ms
Your package was pushed.

No HTTP 401. The job_workflow_ref claim now names this repository's own publish-release.yml, which is what nuget.org validates against the package owner.

The .snupkg finding is settled, and the decline was right. The suppressed finding on publish-release.yml:120 claimed the symbol package "will never be uploaded" and that "dotnet nuget push does not implicitly upload the co-located .snupkg". The same run, same step, immediately after the line above:

Pushing ***.LanguageTags.1.5.71-ge44eb09d39.snupkg to 'https://www.nuget.org/api/v2/symbolpackage'...
Created https://www.nuget.org/api/v2/symbolpackage/ 153ms
Your package was pushed.

One dotnet nuget push ./nuget/*.nupkg invocation, two packages pushed, the symbol one to the symbol server. The comment this PR carries is accurate and no change was owed.

The coverage package swap works.Microsoft.Testing.Extensions.CodeCoverage 18.9.0 under the hub validator's own invocation reported total: 310, failed: 0, succeeded: 310. Worth stating explicitly because the PR description flagged that dotnet test reports "Zero tests ran" on the authoring host: that is confirmed local-only, and it reproduced on a pristine develop checkout there before this change too.

The release-asset rename is confirmed, as the description predicted: the release carries LICENSE, nuget.7z, and README.md, where previous releases carried LanguageTags.7z.

One observation, pre-existing rather than introduced here: the develop prerelease is 1.5.71 while main is at 1.5.90, because NBGV computes git height and develop takes squash merges (one commit each) while main takes merge commits (which bring the whole develop commit list). The previous develop prerelease sat at 1.5.65 against a 1.5.88 main for the same reason. Flagging it rather than treating it as this PR's business.

[ptr727]

Replaces this repository's three local copies of hub-hosted task workflows with caller stubs pinned to the hub at 2.0.539, and reshapes the publisher so the NuGet push runs from this repository rather than from a hub task.

Second of three PRs against audit run 2026-09-02T00:53:04Z | hub a9afa1d. It closes every remaining interface: and hub-only: finding in that run.

Why the push has to move

NuGet.org validates the OIDC token's job_workflow_ref claim against the package owner, so a push running from ptr727/ProjectTemplate's build-release-task.yml is rejected with HTTP 401 (ptr727/ProjectTemplate#1126). The hub task therefore builds and uploads nuget-build-<branch>, and the new publish-nuget job here downloads that artifact and pushes, which is what makes the claim name this repository.

A smoke build never reaches either push, so no pull request can catch this. The first real release is where it would have surfaced.

The dispatch safeguards, verified rather than assumed

main and develop both dispatch, and they cannot cross channels:

• publish-plan-task.yml accepts workflow_dispatch from main or develop only. Any other ref is a hard ::error:: exit, not a silent skip.
• build-release-task.yml's validate-release job runs before any build or push, and refuses a main version carrying a prerelease suffix, or a non-main version lacking one.
• The GitHub release is stamped prerelease: ${{ inputs.branch != 'main' }}.
• version.json already pins publicReleaseRefSpec to ^refs/heads/main$, so NBGV stamps the suffix correctly on both legs.

The push trigger narrows to main, because the plan task's push arm publishes only for main plus a bot actor, so listing develop would be inert.

What changed

• Deletedbuild-release-task.yml, validate-task.yml, and run-codegen-pull-request-task.yml, per the retire dispositions in the hub's spec/divergences.json.
• publish-release.yml gains the required plan job and the needs.validate.result == 'success' gate the audit reported missing, plus publish-nuget.
• merge-bot-pull-request.yml gains the required merge-bot job as a hub stub.
• test-pull-request.yml gains a changes paths-filter job whose entries are the publisher's own shipped-input list, so the smoke gate and the publish gate agree on what affects the package by construction. CODECOV_TOKEN is mapped explicitly rather than inherited, since secrets: inherit on a cross-repository call would hand the hub validator every secret this repository holds.
• Two new hooks the hub tasks call: .github/actions/validate/action.yml carries the codegen-drift guard that used to live in the local validate task, and .github/actions/codegen/action.yml carries the generator invocation.
• Coverage package swapped from coverlet.MTP to Microsoft.Testing.Extensions.CodeCoverage 18.9.0, which is what the hub validator's coverage invocation drives, per WORKFLOW.md D1.6.
• WORKFLOW.md carried whole from the hub, which brings D9.3's set -Eeuo pipefail with it and closesWorkflows and WORKFLOW.md State set -euo pipefail Where the Hub Requires set -Eeuo pipefail #335.
• OPERATIONS.md corrected in three places where it still described the replaced pipeline, and LanguageTags.slnx's GitHub folder refreshed.

Behavior changes worth knowing

• The GitHub release asset is renamed. The deleted local leaf archived to LanguageTags.7z; the hub default archives to nuget.7z and attaches it as release-asset-<branch>-nuget. Nothing in the repo links the old name.
• A develop -> main promotion merge no longer publishes. That is the point of the plan gate, and it closes the auto-publish gap CodeRabbit raised on Promote develop to main #329. Releasing a promotion is now a deliberate dispatch against main.
• A shipped-input merge to develop no longer publishes a prerelease. A develop prerelease is dispatch-only.
• The nuget.org trusted-publishing policy has already been repointed at publish-release.yml by the maintainer, so the first release after this merge is not blocked on it.

Verification

• All 18 CI checks green, which is the real proof: this is the first run in which the hub reusable workflows actually execute for this repository, including the smoke build going through build-release-task.yml by pin and the codegen-drift guard running as the new validate hook.
• dotnet build: 0 warnings, 0 errors. The offline codegen regeneration produces no drift.
• All four workflows pass actionlint; both composite actions parse.
• Repo gate resolved all 7 hub pins against GitHub. eol, eol-coverage, sha-pin clean.
• Full Docker doc-lint set: 6 linters completed. Diff-scoped prose gate: clean.
• A local strict review pass checked each hub call's input, secret, and permission contract against the task definition at the pinned commit, plus the artifact-name match on the OIDC seam and the job gating. It raised 6 findings; four were real prose gaps this change created, fixed before the PR opened.

Review loop

3 rounds across Copilot, CodeRabbit, and Qodo. 5 threads, all resolved.

Fixed:README.md added to both shipped-input lists, after verifying LanguageTags.csproj packs it (PackageReadmeFile plus a Pack="true" item). Without it a README-only bot push to main would not republish, leaving a stale readme on the gallery page, and a README-only PR would skip the smoke build. The PR title was also 77 characters against the 72-character limit and is now 60.

Declined with evidence: that the smoke build omits ref (it is required: false, default: '', and actions/checkout resolves an empty ref to the triggering event's ref, which on a pull_request is the merge ref; the publish job does pass ref: ${{ github.sha }}, where pinning matters). That GOVERNANCE.md should capitalize "Hub" (lowercase is the carried convention, 31 times in the canonical GOVERNANCE.md alone). And that the .snupkg is never pushed, which is answered in the conversation: the hub action uploads *.snupkg alongside *.nupkg into the artifact, dotnet nuget push pushes a co-located symbol package unless --no-symbols is passed, and the deleted local task carried the identical command, so symbol publishing is unchanged rather than newly broken.

Known remaining

Coverage is PARTIAL, 14 of 15 files, and no round names the unread file. The tooling reports that a re-request has never cleared this and routes the decision to the maintainer.

One suppressed finding stays counted on head, the .snupkg one above. It is declined rather than unanswered; a suppressed finding has no resolve API, so it is counted from the round it is raised in regardless of the answer.

High-Level Assessment

The following are alternative approaches to this PR:

1. Keep the release task local

• ➕ Preserves a repository-local OIDC workflow claim
• ➕ Keeps build, release, and NuGet publication in one reusable workflow
• ➖ Continues duplicating fleet release logic
• ➖ Misses centralized hub fixes and contract improvements
• ➖ Requires this repository to maintain versioning and artifact orchestration

2. Use a long-lived NuGet API key

• ➕ Avoids dependency on the OIDC job_workflow_ref claim
• ➕ Could leave publication inside the hub workflow
• ➖ Introduces a persistent high-value secret
• ➖ Weakens least-privilege and credential-rotation posture
• ➖ Conflicts with the fleet trusted-publishing contract

Recommendation: Use the PR's artifact-handoff design. It centralizes reusable planning, validation, and build behavior while keeping only the identity-sensitive NuGet push local, preserving OIDC trusted publishing and tightly scoping id-token permission. Keeping the entire release task local would solve the claim issue but retain substantial duplicated infrastructure; an API key would solve it at an unacceptable security cost.

🔵 Needs a closer look

It substantially changes release/publish workflow behavior (including OIDC NuGet publishing seams) in ways that are difficult to fully validate without end-to-end release execution.

Pull request overview

This PR adopts the hub’s reusable GitHub Actions workflows (pinned to 2.0.539) and reshapes the release pipeline so the NuGet push executes in this repository’s workflow context (to satisfy NuGet.org OIDC job_workflow_ref validation). It also updates the repo’s workflow/runbook documentation and aligns test coverage tooling with the hub validator.

Changes:

• Replaced locally-carried reusable workflows with caller stubs pinned to the hub, and introduced repo-owned composite hooks for validation (codegen drift guard) and codegen execution.
• Updated the publisher to add a plan gate and moved the NuGet push into a repo-local publish-nuget job that consumes the hub build artifact.
• Swapped coverage tooling from coverlet.MTP to Microsoft.Testing.Extensions.CodeCoverage and refreshed operational/workflow documentation accordingly.

Answering Qodo's two open findings, which track separately from the review threads.

1. "Smoke build omits ref" (Bug / Correctness). Disproven.

Omitting ref on a smoke call is the contract rather than a gap. Checked against the hub task at the pinned commit a9afa1d:

• build-release-task.yml declares ref as required: false with default: ''. Only branch is required, and both callers here supply it.
• The one use of that input passes it to get-version-task.yml, whose checkout is actions/checkout with ref: ${{ inputs.ref }}. actions/checkout treats an empty ref as unset, resolving to the triggering event's ref, which on a pull_request is the merge ref. So the smoke build versions and packs exactly the tree under review.
• The fleet's reference adoption of this same pattern omits ref on its smoke job too, and supplies it only on the publish job.

publish-release.yml here does pass ref: ${{ github.sha }} on the publish job, because a release must pin the exact commit NBGV versioned rather than a moving ref. Adding it to the smoke job would be actively wrong on a pull_request, where github.sha is the merge commit and pinning it would discard the correct event-ref resolution.

All 18 checks on the reviewed head were green, and that run included the smoke build going through this exact call.

2. "PR title exceeds limit" (Rule violation / Maintainability). Fixed.

The title was 77 characters against the 72-character limit in GOVERNANCE.md "Pull Request Title and Commit Message Conventions". It now reads "Adopt the Hub Reusable Workflows and Relocate the NuGet Push", 60 characters, and the lead commit's subject matches.

🟡 Changes recommended

The new shipped-input path filters omit README.md, but the NuGet package embeds it, so README-only changes won’t trigger smoke/publish and can leave the package readme stale.

🔵 Needs a closer look

The new NuGet publish job only pushes *.nupkg, so the repo’s *.snupkg symbol packages will not be published despite symbols being enabled.

Review details

Suppressed comments (1)

Previously missed (1) — in code that hasn't changed since the last review.

.github/workflows/publish-release.yml:120

• The NuGet publish step only pushes *.nupkg, so the symbol package (*.snupkg) produced by this repo (LanguageTags.csproj sets <IncludeSymbols>true</IncludeSymbols> and SymbolPackageFormat=snupkg) will never be uploaded. This also makes the preceding comment inaccurate: dotnet nuget push does not implicitly upload the co-located .snupkg when you push a .nupkg. Push the .snupkg explicitly (or remove symbol generation).

Answering the Suppressed comments (1) block from the Copilot review on 015471f, which opens no thread to resolve, and re-answering one Qodo finding that is already fixed.

1. .github/workflows/publish-release.yml:120 — "The NuGet publish step only pushes *.nupkg, so the symbol package (*.snupkg) ... will never be uploaded. This also makes the preceding comment inaccurate: dotnet nuget push does not implicitly upload the co-located .snupkg when you push a .nupkg." Disproven.

The finding is right that this repository produces a .snupkg (LanguageTags.csproj sets IncludeSymbols and SymbolPackageFormat=snupkg) and right that it must reach nuget.org. It is wrong about the mechanism, on two independently checkable points.

The .snupkg is in the artifact. The hub's nuget-build-default/action.yml uploads both patterns into nuget-build-<branch>:

path: | ${{ runner.temp }}/publish/*.nupkg ${{ runner.temp }}/publish/*.snupkg

So after download-artifact into ./nuget, the two files are co-located, which is the precondition the push relies on. (*.nupkg does not glob the .snupkg, since that name ends in .snupkg.)

dotnet nuget push does push a co-located symbol package. That is what its --no-symbols flag exists to suppress: the documented description is "Doesn't push symbols (even if present)", which only means something if the default is to push them. No --no-symbols is passed here.

And this exact mechanism is what has been shipping this package. The build-release-task.yml this PR deletes carried the same command and the same comment, dotnet nuget push .../publish/*.nupkg with no --no-symbols, against a directory holding both files. This PR moves where that step runs, for the OIDC job_workflow_ref reason in the description, and changes nothing about how symbols are pushed. If the claim held, symbol publishing would already have been broken for every release to date rather than newly broken here.

The comment is accurate as written and stays.

2. Qodo, "PR title exceeds limit". Already fixed and reported in a previous comment. The title is now "Adopt the Hub Reusable Workflows and Relocate the NuGet Push", 60 characters against the 72-character limit, and the lead commit subject matches. Qodo appears not to re-evaluate a title change within a run, so the finding stays open on its side with nothing left to do on this one.

Follow-up now that this has merged and a release has actually run, because two things in this PR could only be proven by a real publish and one of them was a finding I declined.

The publisher was dispatched on develop at run 33592206733. All 12 jobs succeeded, and it produced prerelease 1.5.71-ge44eb09d39.

The relocated OIDC push works. This is the change this PR exists for, and no pull request could exercise it, since a smoke build never reaches a push:

Pushing ***.LanguageTags.1.5.71-ge44eb09d39.nupkg to 'https://www.nuget.org/api/v2/package'...
Created https://www.nuget.org/api/v2/package/ 416ms
Your package was pushed.

No HTTP 401. The job_workflow_ref claim now names this repository's own publish-release.yml, which is what nuget.org validates against the package owner.

The .snupkg finding is settled, and the decline was right. The suppressed finding on publish-release.yml:120 claimed the symbol package "will never be uploaded" and that "dotnet nuget push does not implicitly upload the co-located .snupkg". The same run, same step, immediately after the line above:

Pushing ***.LanguageTags.1.5.71-ge44eb09d39.snupkg to 'https://www.nuget.org/api/v2/symbolpackage'...
Created https://www.nuget.org/api/v2/symbolpackage/ 153ms
Your package was pushed.

One dotnet nuget push ./nuget/*.nupkg invocation, two packages pushed, the symbol one to the symbol server. The comment this PR carries is accurate and no change was owed.

The coverage package swap works.Microsoft.Testing.Extensions.CodeCoverage 18.9.0 under the hub validator's own invocation reported total: 310, failed: 0, succeeded: 310. Worth stating explicitly because the PR description flagged that dotnet test reports "Zero tests ran" on the authoring host: that is confirmed local-only, and it reproduced on a pristine develop checkout there before this change too.

The release-asset rename is confirmed, as the description predicted: the release carries LICENSE, nuget.7z, and README.md, where previous releases carried LanguageTags.7z.

One observation, pre-existing rather than introduced here: the develop prerelease is 1.5.71 while main is at 1.5.90, because NBGV computes git height and develop takes squash merges (one commit each) while main takes merge commits (which bring the whole develop commit list). The previous develop prerelease sat at 1.5.65 against a 1.5.88 main for the same reason. Flagging it rather than treating it as this PR's business.
