Promote Develop to Main

[ptr727]

Promotes the hub resync (#451) to main.

Why this is a promote/ branch rather than develop itself

main carried its own copies of work develop had done independently: the Microsoft.Testing.Platform migration (#448 against #447) and an AwesomeAssertions bump (#450 against #449). Combined with the CRLF-to-LF renormalization, develop -> main conflicts on seven paths, and develop's required_linear_history plus its PR ruleset forbid resolving them on develop. This is the documented remedy: resolve on a throwaway branch off main, then open that into main.

The resolution is provably exactly develop

Every conflict was resolved to develop's side, and the result is byte-identical to develop's tree:

merged tree 503594305d3fe69900452453c806dedded8f1243
develop tree 503594305d3fe69900452453c806dedded8f1243

Each was confirmed lossless before develop was taken, per the documented check:

Path	Why taking develop drops nothing
global.json	Content-identical modulo EOL. main added it CRLF, develop renormalized it.
UtilitiesTests/UtilitiesTests.csproj	Content-identical modulo EOL.
UtilitiesTests/ExtensionsTests.cs	Content-identical modulo EOL.
Directory.Packages.props	Differs in one line, the coverage extension, where develop is the newer 18.10.0 against main's 18.9.0.
Utilities.slnx	main's extra entries are a duplicate dependabot.yml, a Data/ folder naming three files this repository does not contain, and the two workflow tasks develop deleted because the hub now hosts them. Verified each path is absent on develop, and that dependabot.yml is still listed there under GitHub Actions.
.github/workflows/build-release-task.yml	Deleted on develop per its retire disposition.
.github/workflows/validate-task.yml	Deleted on develop, which now calls the hub-hosted validator by pin.

Verification

Run against this branch's tree, not inferred from #451:

dotnet build 0 warnings, 0 errors
dotnet csharpier check . 43 files, clean
dotnet format style --verify-no-changes clean
dotnet test (MTP + coverage) 183/183 passed
markdownlint-cli2 '**/*.md' 48 files, 0 issues
actionlint clean
editorconfig-checker clean
repo_gate.py eol, eol-coverage, sha-pin all clean
prose_lint.py --diff origin/main clean

Merging

The head is promote/develop-to-main, not develop, so the delete-develop trap does not apply here. Merge with a merge commit rather than a squash, per the main ruleset.

📝 Walkthrough

Walkthrough

The pull request centralizes repository governance and agent procedures, adds fleet Skills and documentation, updates GitHub workflow composition, normalizes line endings and formatting, upgrades code coverage tooling, and adds the public StringHistory class with tests.

Changes

Repository governance and Skills

Layer / File(s)	Summary
Centralized governance and agent procedures AGENTS.md, GOVERNANCE.md, CODESTYLE.md, AUDIT.md, ARCHITECTURE.md, OPERATIONS.md, .github/copilot-instructions.md	Repository rules now use concise indexes and shared governance documents. Agent conduct, auditing, resynchronization, worktrees, review, release, and contribution procedures are defined in Skills.
Language, workflow, and documentation Skills .github/skills/*	New Skills define .NET, Python, Shell, workflow, Git, review, release, repository, and documentation procedures with supporting references.
Repository documentation and entry points README.md, CLAUDE.md, HISTORY.md, Utilities.slnx	Project documentation, release history, Claude entry-point guidance, and solution-item organization were updated.

Workflow and repository configuration

Layer / File(s)	Summary
Pinned validation and release workflows .github/workflows/test-pull-request.yml, .github/workflows/publish-release.yml, .github/workflows/merge-bot-pull-request.yml	Workflows now call pinned external reusable tasks, use scoped permissions and secrets, detect release-relevant changes, conditionally run smoke builds, and aggregate skipped jobs correctly.
Removed local reusable workflows .github/workflows/build-release-task.yml, .github/workflows/publish-plan-task.yml, .github/workflows/validate-task.yml	The local release, publish-plan, and validation workflow interfaces were deleted.
Formatting, line endings, and tooling configuration .editorconfig, .gitattributes, .editorconfig-checker.json, .markdownlint-cli2.jsonc, cspell.json, .gitignore, .husky/*, Directory.Packages.props, host-tools.json	LF is now the default with CRLF reserved for batch files. Checker exclusions, Markdown HTML rules, spelling scope, ignore patterns, host-tool declaration, and coverage package version were updated.

Library and tests

Layer / File(s)	Summary
StringHistory implementation and coverage Utilities/StringHistory.cs, UtilitiesTests/StringHistoryTests.cs	Added configurable first-line and last-line retention, bounded rolling behavior, validation, read-only storage, and newline rendering.
Existing source and test normalization Utilities/*.cs, UtilitiesTests/*.cs, Sandbox/*, project files, workspace files	Existing implementations, APIs, tests, assertions, and project settings were reformatted or normalized without stated behavioral changes.

Estimated code review effort: 3 (Moderate) | ~25 minutes

Merge Risk:🟠 High · up to 8af98

The promoted tree contains a malformed .NET tool manifest that blocks tool restoration, mutable history limits that can violate retention or throw on invalid input, and automation/workspace controls that can permit unintended merges or primary-checkout writes. These correctness and security risks make the PR not ready to merge until fixed.

High-Level Assessment

The following are alternative approaches to this PR:

1. Keep reusable workflows in-repo

• ➕ Workflow changes can be exercised directly from the repository head.
• ➕ The repository remains independent of hub availability.
• ➖ Duplicates generic orchestration across the fleet.
• ➖ Requires repeated synchronization and allows stale CI copies to report false conformance.

2. Resolve the promotion directly on develop

• ➕ Would avoid a temporary promotion branch.
• ➕ Keeps the promotion head on the normal integration branch.
• ➖ Develop's linear-history and pull-request rules prevent the required merge resolution.
• ➖ A back-merge would violate the forward-only branch model.

Recommendation: Use the current throwaway branch from main, resolve verified conflicts to develop's tree, and consume generic CI through commit-pinned hub workflows. This preserves branch protections, produces the proven develop-equivalent tree, and removes duplicated workflow maintenance while retaining repository-owned caller configuration.

🐞 Bugs (0)📘 Rule violations (0)📜 Skill insights (0)

1. README edits mixed with normalization✗ Dismissed📘 Rule violation⚙ Maintainability

Description

README.md combines a whole-file CRLF-to-LF rewrite with substantive additions including a table of
contents and new sections. This prevents the normalization from being reviewed as an isolated
EOL-only change.

Code

README.md[R39-42]

+## Table of Contents++- [Build and Distribution](#build-and-distribution)+ - [Build Status](#build-status)

Relevance

●●● Strong

The finding identifies substantive README additions in a file also rewritten for EOL normalization,
directly violating the isolation rule.

ⓘ Recommendations generated based on similar findings in past PRs

Evidence

Rule 2826678 allows EOL normalization only when visible content is unchanged. The patch replaces the
full 84-line base file with a 154-line file, and the cited newly added table of contents is a
substantive content change.

2. Comments cite requirement identifiers✗ Dismissed📘 Rule violation⚙ Maintainability

Description

The workflow comments cite D1.1, D1.4, S2, and S3 while explaining the job. These
governance-style identifiers are not change-local implementation context and violate the restriction
on policy or standard references in code-review comments.

Code

.github/workflows/test-pull-request.yml[R27-29]

+ # This repository builds one release target, the NuGet package (D1.1).+ # The filter 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.+ # Naming the inputs rather than excluding workflow files means a documentation-only or workflow-only pull request skips the smoke build rather than packing the library for nothing (D1.4, and scenarios S2 and S3).

Relevance

●●● Strong

Explicit comment rule directly prohibits governance identifiers; removing those references is a
deterministic local edit.

ⓘ Recommendations generated based on similar findings in past PRs

Evidence

Rule 2826588 explicitly prohibits comments that cite governance documents, standards, or policy IDs.
The cited added comment block contains multiple such identifiers.

3. Comment references external hub✗ Dismissed📘 Rule violation⚙ Maintainability

Description

The new merge-bot comment refers to the hub and to every fleet repo, describing cross-repository
architecture rather than only the local workflow. The checklist disallows comments that name or
discuss another repository, service, or project.

Code

.github/workflows/merge-bot-pull-request.yml[R3-4]

+# Thin caller: the merge-bot is the hub's reusable merge-bot-task.yml, which every fleet repo reaches rather than carries.+# The trigger is pull_request_target so the called workflow resolves from the trusted base rather than the PR head, and no job checks out PR code.

Relevance

●●● Strong

Explicit repository rule directly prohibits external-repository discussion; removing the comment is
a straightforward local fix.

ⓘ Recommendations generated based on similar findings in past PRs

Evidence

Rule 2826588 restricts comments to the surrounding file and prohibits references to other
repositories, services, or projects. The cited added comment explicitly discusses the hub's reusable
task and fleet repositories.

4. Workflow embeds extensive rationale✗ Dismissed📘 Rule violation⚙ Maintainability

Description

The changes job is preceded by a multi-line architectural rationale covering release targets,
publisher inputs, and several requirement scenarios. Workflow guidance requires this high-level
rationale to be consolidated into a single-line top summary rather than scattered above jobs.

Code

.github/workflows/test-pull-request.yml[R27-29]

+ # This repository builds one release target, the NuGet package (D1.1).+ # The filter 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.+ # Naming the inputs rather than excluding workflow files means a documentation-only or workflow-only pull request skips the smoke build rather than packing the library for nothing (D1.4, and scenarios S2 and S3).

Relevance

●●● Strong

Explicit workflow-comment rule directly requires concise summaries instead of scattered multi-line
architectural rationale.

ⓘ Recommendations generated based on similar findings in past PRs

Evidence

Rule 2826632 disallows large top-level rationale comments scattered across workflow jobs. The cited
three-line block explains release architecture and multiple scenarios rather than a short local
implementation detail.

5. Package bump mixed with normalization✗ Dismissed📘 Rule violation⚙ Maintainability

Description

Directory.Packages.props is wholly rewritten for CRLF-to-LF normalization while also changing the
code-coverage package from 18.9.0 to 18.10.0. Mixing a substantive dependency edit into the
normalized file violates the required isolation of EOL-only changes.

Code

Directory.Packages.props[8]

+ <PackageVersion Include="Microsoft.Testing.Extensions.CodeCoverage" Version="18.10.0" />

Relevance

●●● Strong

The finding identifies a concrete token change inside an EOL-normalized file, directly violating the
stated isolation rule.

ⓘ Recommendations generated based on similar findings in past PRs

Evidence

Rule 2826678 requires an EOL-normalized file to contain no token changes. The diff removes and
re-adds all 16 lines while the cited declaration changes Microsoft.Testing.Extensions.CodeCoverage
from 18.9.0 to 18.10.0.

🔵 Needs a closer look

It combines broad CI/publish workflow rewiring (hub-hosted calls, permissions/secrets scoping) with large-scale repo normalization and retirements that warrants final human validation.

Pull request overview

Promotes the develop branch state into main by aligning repository configuration, documentation, tooling, and CI wiring with the hub-resynced setup (including LF normalization and hub-hosted reusable workflows).

Changes:

• Normalize/standardize repo files (formatting and LF line endings) and refresh solution/workspace metadata.
• Move CI orchestration to hub-hosted reusable workflows and retire repo-local workflow task implementations/config payloads.
• Add/refresh carried skills and governance/architecture documentation to match the current fleet model.

[ptr727]

Answering the two Qodo review-body findings here, since they carry no thread to resolve. Both also have inline threads, which are answered and resolved there.

"Comments cite requirement identifiers" (test-pull-request.yml, citing D1.1, D1.4, S2, S3). Declined. Those identifiers are defined in WORKFLOW.md, which this repository carries and which this pull request changes, so they are pointers into this repository's own CI contract rather than an external policy reference. D1.1 and D1.4 are the guarantees the changes job implements, and S2 and S3 are the scenarios in that same file's test-methodology table asserting that a documentation-only and a workflow-only pull request skip the smoke build. The reference caller stub this file is adopted from carries the same citations verbatim, including (D1.1) on the filter and (D1.5, D7.4) on the aggregator.

"Comment references external hub" (merge-bot-pull-request.yml). Half declined, half taken. The rule invoked governs carried template files and states its own boundary, that a repository's own content is outside it, and a workflow is repository-owned. The reference is also in the runnable body rather than only the prose, since the job is uses: ptr727/ProjectTemplate/.github/workflows/merge-bot-task.yml@f3b4cc9. The wording point is fair though: "which every fleet repo reaches rather than carries" describes other repositories, and this repository's file has no reason to. That reword goes to develop rather than here, because this promotion's tree is byte-identical to develop's and editing it would leave main ahead on that file, which is the drift this promotion exists to remove.

The remaining two Qodo findings from the first round, on mixing the package bump and the README rewrite with the line-ending normalization, are answered in their own threads: the line-endings rule permits a broader maintenance change to normalize alongside content edits when it is called out and the content is verified separately with git diff --ignore-cr-at-eol, and both conditions are met.

Inline comments:
In @.config/dotnet-tools.json:
- Line 19: Close the root JSON object in the dotnet-tools manifest after the
tools object so the document is valid JSON and dotnet tool restore can parse it
successfully.
In @.github/skills/drive-pr/SKILL.md:
- Around line 46-48: Update the drive skill’s authorization guidance so
answering the how-far question only selects the target and cannot authorize a
feature-to-develop squash merge. Require separate explicit confirmation naming
that merge action before step 4 proceeds, or enforce an authenticated
maintainer-only invocation boundary, while preserving the prohibition on
develop-to-main promotion and release dispatch authorization.
In @.github/skills/git-commit-conventions/SKILL.md:
- Around line 89-90: Update the PowerShell instructions around the git init and
commit command to declare PowerShell 7 or later as a prerequisite, or replace
the && chain with explicit exit-code checks so the commands remain compatible
with Windows PowerShell 5.1.
In
@.github/skills/operational-vs-release-workflow/references/branch-protection-and-promotion.md:
- Around line 35-38: Update the merge-resolution workflow after resolving
EOL-conflicted files with git checkout --theirs <file>: stage every
resolved path using git add or git rm, then complete the merge with git commit
or git merge --continue before opening the promotion PR.
In @.github/skills/repo-worktree/SKILL.md:
- Around line 141-142: Update gh-write-guard.py so
GH_WRITE_GUARD_ALLOW_PRIMARY_CHECKOUT bypasses protection only for the approved
standalone-clone fallback path, validating the target path before allowing the
mutation. Keep primary-checkout writes denied even when the session variable is
non-falsy, and preserve the existing fallback checkout behavior.
In @.vscode/tasks.json:
- Line 142: Update the four lint task definitions in tasks.json to invoke
scripts/docker_lint.py instead of direct docker run commands, preserving each
task’s lint purpose and arguments. Ensure they use the governed wrapper’s digest
resolution, read-only workspace mounts, disabled networking, and timeout
controls rather than :latest images and writable mounts.
In `@AUDIT.md`:
- Line 28: Update the prose in AUDIT.md to replace “afterwards” with “afterward”
near the Fleet Bootstrap guidance, and replace “all-drifts” with a clear phrase
such as “PR that addresses all drift classes” at the later occurrence.
In `@GOVERNANCE.md`:
- Line 221: Update the boolean-input guidance in GOVERNANCE.md (lines 221-221)
and .github/skills/workflow-ci-contract/SKILL.md (lines 27-27): use direct
Boolean checks through inputs.foo, and only compare against string values when
reading github.event.inputs.foo. Keep the documented workflow_call and
workflow_dispatch declarations accurate in both documents.
In `@OPERATIONS.md`:
- Around line 27-30: Update the Docker image references in the documented
validation commands, including the repeated commands around the actionlint and
editorconfig-checker entries, to use approved immutable digests instead of
mutable tags such as latest. Preserve each command’s existing arguments and
update digests deliberately when changing image versions.
In `@Utilities/StringHistory.cs`:
- Around line 84-90: Update MaxFirstLines and MaxLastLines so limits cannot be
negative and changing them preserves retention immediately: either make the
properties initialization-only or, in their setters, re-partition _stringList
and synchronize _firstLines and _lastLines. Ensure subsequent appends never
retain more than the configured first and last limits.
- Line 82: Update the limit documentation near AppendLine and the corresponding
constructor parameter to describe one-sided zero behavior accurately: when one
limit is zero and the other is positive, retain entries only according to the
positive limit on that side, rather than stating that zero means no limit.

Promotes the hub resync (#451) to main.

Why this is a promote/ branch rather than develop itself

main carried its own copies of work develop had done independently: the Microsoft.Testing.Platform migration (#448 against #447) and an AwesomeAssertions bump (#450 against #449). Combined with the CRLF-to-LF renormalization, develop -> main conflicts on seven paths, and develop's required_linear_history plus its PR ruleset forbid resolving them on develop. This is the documented remedy: resolve on a throwaway branch off main, then open that into main.

The resolution is provably exactly develop

Every conflict was resolved to develop's side, and the result is byte-identical to develop's tree:

merged tree 503594305d3fe69900452453c806dedded8f1243
develop tree 503594305d3fe69900452453c806dedded8f1243

Each was confirmed lossless before develop was taken, per the documented check:

Path	Why taking develop drops nothing
global.json	Content-identical modulo EOL. main added it CRLF, develop renormalized it.
UtilitiesTests/UtilitiesTests.csproj	Content-identical modulo EOL.
UtilitiesTests/ExtensionsTests.cs	Content-identical modulo EOL.
Directory.Packages.props	Differs in one line, the coverage extension, where develop is the newer 18.10.0 against main's 18.9.0.
Utilities.slnx	main's extra entries are a duplicate dependabot.yml, a Data/ folder naming three files this repository does not contain, and the two workflow tasks develop deleted because the hub now hosts them. Verified each path is absent on develop, and that dependabot.yml is still listed there under GitHub Actions.
.github/workflows/build-release-task.yml	Deleted on develop per its retire disposition.
.github/workflows/validate-task.yml	Deleted on develop, which now calls the hub-hosted validator by pin.

Verification

Run against this branch's tree, not inferred from #451:

dotnet build 0 warnings, 0 errors
dotnet csharpier check . 43 files, clean
dotnet format style --verify-no-changes clean
dotnet test (MTP + coverage) 183/183 passed
markdownlint-cli2 '**/*.md' 48 files, 0 issues
actionlint clean
editorconfig-checker clean
repo_gate.py eol, eol-coverage, sha-pin all clean
prose_lint.py --diff origin/main clean

Merging

The head is promote/develop-to-main, not develop, so the delete-develop trap does not apply here. Merge with a merge commit rather than a squash, per the main ruleset.

📝 Walkthrough

Walkthrough

The pull request centralizes repository governance and agent procedures, adds fleet Skills and documentation, updates GitHub workflow composition, normalizes line endings and formatting, upgrades code coverage tooling, and adds the public StringHistory class with tests.

Changes

Repository governance and Skills

Layer / File(s)	Summary
Centralized governance and agent procedures AGENTS.md, GOVERNANCE.md, CODESTYLE.md, AUDIT.md, ARCHITECTURE.md, OPERATIONS.md, .github/copilot-instructions.md	Repository rules now use concise indexes and shared governance documents. Agent conduct, auditing, resynchronization, worktrees, review, release, and contribution procedures are defined in Skills.
Language, workflow, and documentation Skills .github/skills/*	New Skills define .NET, Python, Shell, workflow, Git, review, release, repository, and documentation procedures with supporting references.
Repository documentation and entry points README.md, CLAUDE.md, HISTORY.md, Utilities.slnx	Project documentation, release history, Claude entry-point guidance, and solution-item organization were updated.

Workflow and repository configuration

Layer / File(s)	Summary
Pinned validation and release workflows .github/workflows/test-pull-request.yml, .github/workflows/publish-release.yml, .github/workflows/merge-bot-pull-request.yml	Workflows now call pinned external reusable tasks, use scoped permissions and secrets, detect release-relevant changes, conditionally run smoke builds, and aggregate skipped jobs correctly.
Removed local reusable workflows .github/workflows/build-release-task.yml, .github/workflows/publish-plan-task.yml, .github/workflows/validate-task.yml	The local release, publish-plan, and validation workflow interfaces were deleted.
Formatting, line endings, and tooling configuration .editorconfig, .gitattributes, .editorconfig-checker.json, .markdownlint-cli2.jsonc, cspell.json, .gitignore, .husky/*, Directory.Packages.props, host-tools.json	LF is now the default with CRLF reserved for batch files. Checker exclusions, Markdown HTML rules, spelling scope, ignore patterns, host-tool declaration, and coverage package version were updated.

Library and tests

Layer / File(s)	Summary
StringHistory implementation and coverage Utilities/StringHistory.cs, UtilitiesTests/StringHistoryTests.cs	Added configurable first-line and last-line retention, bounded rolling behavior, validation, read-only storage, and newline rendering.
Existing source and test normalization Utilities/*.cs, UtilitiesTests/*.cs, Sandbox/*, project files, workspace files	Existing implementations, APIs, tests, assertions, and project settings were reformatted or normalized without stated behavioral changes.

Estimated code review effort: 3 (Moderate) | ~25 minutes

Merge Risk:🟠 High · up to 8af98

The promoted tree contains a malformed .NET tool manifest that blocks tool restoration, mutable history limits that can violate retention or throw on invalid input, and automation/workspace controls that can permit unintended merges or primary-checkout writes. These correctness and security risks make the PR not ready to merge until fixed.

High-Level Assessment

The following are alternative approaches to this PR:

1. Keep reusable workflows in-repo

• ➕ Workflow changes can be exercised directly from the repository head.
• ➕ The repository remains independent of hub availability.
• ➖ Duplicates generic orchestration across the fleet.
• ➖ Requires repeated synchronization and allows stale CI copies to report false conformance.

2. Resolve the promotion directly on develop

• ➕ Would avoid a temporary promotion branch.
• ➕ Keeps the promotion head on the normal integration branch.
• ➖ Develop's linear-history and pull-request rules prevent the required merge resolution.
• ➖ A back-merge would violate the forward-only branch model.

Recommendation: Use the current throwaway branch from main, resolve verified conflicts to develop's tree, and consume generic CI through commit-pinned hub workflows. This preserves branch protections, produces the proven develop-equivalent tree, and removes duplicated workflow maintenance while retaining repository-owned caller configuration.

🐞 Bugs (0)📘 Rule violations (0)📜 Skill insights (0)

1. README edits mixed with normalization✗ Dismissed📘 Rule violation⚙ Maintainability

Description

README.md combines a whole-file CRLF-to-LF rewrite with substantive additions including a table of
contents and new sections. This prevents the normalization from being reviewed as an isolated
EOL-only change.

Code

README.md[R39-42]

+## Table of Contents++- [Build and Distribution](#build-and-distribution)+ - [Build Status](#build-status)

Relevance

●●● Strong

The finding identifies substantive README additions in a file also rewritten for EOL normalization,
directly violating the isolation rule.

ⓘ Recommendations generated based on similar findings in past PRs

Evidence

Rule 2826678 allows EOL normalization only when visible content is unchanged. The patch replaces the
full 84-line base file with a 154-line file, and the cited newly added table of contents is a
substantive content change.

2. Comments cite requirement identifiers✗ Dismissed📘 Rule violation⚙ Maintainability

Description

The workflow comments cite D1.1, D1.4, S2, and S3 while explaining the job. These
governance-style identifiers are not change-local implementation context and violate the restriction
on policy or standard references in code-review comments.

Code

.github/workflows/test-pull-request.yml[R27-29]

+ # This repository builds one release target, the NuGet package (D1.1).+ # The filter 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.+ # Naming the inputs rather than excluding workflow files means a documentation-only or workflow-only pull request skips the smoke build rather than packing the library for nothing (D1.4, and scenarios S2 and S3).

Relevance

●●● Strong

Explicit comment rule directly prohibits governance identifiers; removing those references is a
deterministic local edit.

ⓘ Recommendations generated based on similar findings in past PRs

3. Comment references external hub✗ Dismissed📘 Rule violation⚙ Maintainability

Description

The new merge-bot comment refers to the hub and to every fleet repo, describing cross-repository
architecture rather than only the local workflow. The checklist disallows comments that name or
discuss another repository, service, or project.

Code

.github/workflows/merge-bot-pull-request.yml[R3-4]

+# Thin caller: the merge-bot is the hub's reusable merge-bot-task.yml, which every fleet repo reaches rather than carries.+# The trigger is pull_request_target so the called workflow resolves from the trusted base rather than the PR head, and no job checks out PR code.

Relevance

●●● Strong

Explicit repository rule directly prohibits external-repository discussion; removing the comment is
a straightforward local fix.

ⓘ Recommendations generated based on similar findings in past PRs

Evidence

Rule 2826588 restricts comments to the surrounding file and prohibits references to other
repositories, services, or projects. The cited added comment explicitly discusses the hub's reusable
task and fleet repositories.

4. Workflow embeds extensive rationale✗ Dismissed📘 Rule violation⚙ Maintainability

Description

The changes job is preceded by a multi-line architectural rationale covering release targets,
publisher inputs, and several requirement scenarios. Workflow guidance requires this high-level
rationale to be consolidated into a single-line top summary rather than scattered above jobs.

Code

.github/workflows/test-pull-request.yml[R27-29]

+ # This repository builds one release target, the NuGet package (D1.1).+ # The filter 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.+ # Naming the inputs rather than excluding workflow files means a documentation-only or workflow-only pull request skips the smoke build rather than packing the library for nothing (D1.4, and scenarios S2 and S3).

Explicit workflow-comment rule directly requires concise summaries instead of scattered multi-line
architectural rationale.

5. Package bump mixed with normalization✗ Dismissed📘 Rule violation⚙ Maintainability

Description

Directory.Packages.props is wholly rewritten for CRLF-to-LF normalization while also changing the
code-coverage package from 18.9.0 to 18.10.0. Mixing a substantive dependency edit into the
normalized file violates the required isolation of EOL-only changes.

Code

Directory.Packages.props[8]

+ <PackageVersion Include="Microsoft.Testing.Extensions.CodeCoverage" Version="18.10.0" />

Relevance

●●● Strong

The finding identifies a concrete token change inside an EOL-normalized file, directly violating the
stated isolation rule.

ⓘ Recommendations generated based on similar findings in past PRs

Evidence

Rule 2826678 requires an EOL-normalized file to contain no token changes. The diff removes and
re-adds all 16 lines while the cited declaration changes Microsoft.Testing.Extensions.CodeCoverage
from 18.9.0 to 18.10.0.

🔵 Needs a closer look

It combines broad CI/publish workflow rewiring (hub-hosted calls, permissions/secrets scoping) with large-scale repo normalization and retirements that warrants final human validation.

Pull request overview

Promotes the develop branch state into main by aligning repository configuration, documentation, tooling, and CI wiring with the hub-resynced setup (including LF normalization and hub-hosted reusable workflows).

Changes:

• Normalize/standardize repo files (formatting and LF line endings) and refresh solution/workspace metadata.
• Move CI orchestration to hub-hosted reusable workflows and retire repo-local workflow task implementations/config payloads.
• Add/refresh carried skills and governance/architecture documentation to match the current fleet model.

[ptr727]

Answering the two Qodo review-body findings here, since they carry no thread to resolve. Both also have inline threads, which are answered and resolved there.

"Comments cite requirement identifiers" (test-pull-request.yml, citing D1.1, D1.4, S2, S3). Declined. Those identifiers are defined in WORKFLOW.md, which this repository carries and which this pull request changes, so they are pointers into this repository's own CI contract rather than an external policy reference. D1.1 and D1.4 are the guarantees the changes job implements, and S2 and S3 are the scenarios in that same file's test-methodology table asserting that a documentation-only and a workflow-only pull request skip the smoke build. The reference caller stub this file is adopted from carries the same citations verbatim, including (D1.1) on the filter and (D1.5, D7.4) on the aggregator.

"Comment references external hub" (merge-bot-pull-request.yml). Half declined, half taken. The rule invoked governs carried template files and states its own boundary, that a repository's own content is outside it, and a workflow is repository-owned. The reference is also in the runnable body rather than only the prose, since the job is uses: ptr727/ProjectTemplate/.github/workflows/merge-bot-task.yml@f3b4cc9. The wording point is fair though: "which every fleet repo reaches rather than carries" describes other repositories, and this repository's file has no reason to. That reword goes to develop rather than here, because this promotion's tree is byte-identical to develop's and editing it would leave main ahead on that file, which is the drift this promotion exists to remove.

The remaining two Qodo findings from the first round, on mixing the package bump and the README rewrite with the line-ending normalization, are answered in their own threads: the line-endings rule permits a broader maintenance change to normalize alongside content edits when it is called out and the content is verified separately with git diff --ignore-cr-at-eol, and both conditions are met.

- Line 28: Update the prose in AUDIT.md to replace “afterwards” with “afterward”
near the Fleet Bootstrap guidance, and replace “all-drifts” with a clear phrase
such as “PR that addresses all drift classes” at the later occurrence.
In `@GOVERNANCE.md`:
- Line 221: Update the boolean-input guidance in GOVERNANCE.md (lines 221-221)
and .github/skills/workflow-ci-contract/SKILL.md (lines 27-27): use direct
Boolean checks through inputs.foo, and only compare against string values when
reading github.event.inputs.foo. Keep the documented workflow_call and
workflow_dispatch declarations accurate in both documents.
In `@OPERATIONS.md`:
- Around line 27-30: Update the Docker image references in the documented
validation commands, including the repeated commands around the actionlint and
editorconfig-checker entries, to use approved immutable digests instead of
mutable tags such as latest. Preserve each command’s existing arguments and
update digests deliberately when changing image versions.
In `@Utilities/StringHistory.cs`:
- Around line 84-90: Update MaxFirstLines and MaxLastLines so limits cannot be
negative and changing them preserves retention immediately: either make the
properties initialization-only or, in their setters, re-partition _stringList
and synchronize _firstLines and _lastLines. Ensure subsequent appends never
retain more than the configured first and last limits.
- Line 82: Update the limit documentation near AppendLine and the corresponding
constructor parameter to describe one-sided zero behavior accurately: when one
limit is zero and the other is positive, retain entries only according to the
positive limit on that side, rather than stating that zero means no limit.

Promotes the hub resync (#451) to main.

Why this is a promote/ branch rather than develop itself

main carried its own copies of work develop had done independently: the Microsoft.Testing.Platform migration (#448 against #447) and an AwesomeAssertions bump (#450 against #449). Combined with the CRLF-to-LF renormalization, develop -> main conflicts on seven paths, and develop's required_linear_history plus its PR ruleset forbid resolving them on develop. This is the documented remedy: resolve on a throwaway branch off main, then open that into main.

The resolution is provably exactly develop

Every conflict was resolved to develop's side, and the result is byte-identical to develop's tree:

merged tree 503594305d3fe69900452453c806dedded8f1243
develop tree 503594305d3fe69900452453c806dedded8f1243

Each was confirmed lossless before develop was taken, per the documented check:

Path	Why taking develop drops nothing
global.json	Content-identical modulo EOL. main added it CRLF, develop renormalized it.
UtilitiesTests/UtilitiesTests.csproj	Content-identical modulo EOL.
UtilitiesTests/ExtensionsTests.cs	Content-identical modulo EOL.
Directory.Packages.props	Differs in one line, the coverage extension, where develop is the newer 18.10.0 against main's 18.9.0.
Utilities.slnx	main's extra entries are a duplicate dependabot.yml, a Data/ folder naming three files this repository does not contain, and the two workflow tasks develop deleted because the hub now hosts them. Verified each path is absent on develop, and that dependabot.yml is still listed there under GitHub Actions.
.github/workflows/build-release-task.yml	Deleted on develop per its retire disposition.
.github/workflows/validate-task.yml	Deleted on develop, which now calls the hub-hosted validator by pin.

Verification

Run against this branch's tree, not inferred from #451:

dotnet build 0 warnings, 0 errors
dotnet csharpier check . 43 files, clean
dotnet format style --verify-no-changes clean
dotnet test (MTP + coverage) 183/183 passed
markdownlint-cli2 '**/*.md' 48 files, 0 issues
actionlint clean
editorconfig-checker clean
repo_gate.py eol, eol-coverage, sha-pin all clean
prose_lint.py --diff origin/main clean

Merging

The head is promote/develop-to-main, not develop, so the delete-develop trap does not apply here. Merge with a merge commit rather than a squash, per the main ruleset.

📝 Walkthrough

Walkthrough

The pull request centralizes repository governance and agent procedures, adds fleet Skills and documentation, updates GitHub workflow composition, normalizes line endings and formatting, upgrades code coverage tooling, and adds the public StringHistory class with tests.

Changes

Repository governance and Skills

Layer / File(s)	Summary
Centralized governance and agent procedures AGENTS.md, GOVERNANCE.md, CODESTYLE.md, AUDIT.md, ARCHITECTURE.md, OPERATIONS.md, .github/copilot-instructions.md	Repository rules now use concise indexes and shared governance documents. Agent conduct, auditing, resynchronization, worktrees, review, release, and contribution procedures are defined in Skills.
Language, workflow, and documentation Skills .github/skills/*	New Skills define .NET, Python, Shell, workflow, Git, review, release, repository, and documentation procedures with supporting references.
Repository documentation and entry points README.md, CLAUDE.md, HISTORY.md, Utilities.slnx	Project documentation, release history, Claude entry-point guidance, and solution-item organization were updated.

Workflow and repository configuration

Layer / File(s)	Summary
Pinned validation and release workflows .github/workflows/test-pull-request.yml, .github/workflows/publish-release.yml, .github/workflows/merge-bot-pull-request.yml	Workflows now call pinned external reusable tasks, use scoped permissions and secrets, detect release-relevant changes, conditionally run smoke builds, and aggregate skipped jobs correctly.
Removed local reusable workflows .github/workflows/build-release-task.yml, .github/workflows/publish-plan-task.yml, .github/workflows/validate-task.yml	The local release, publish-plan, and validation workflow interfaces were deleted.
Formatting, line endings, and tooling configuration .editorconfig, .gitattributes, .editorconfig-checker.json, .markdownlint-cli2.jsonc, cspell.json, .gitignore, .husky/*, Directory.Packages.props, host-tools.json	LF is now the default with CRLF reserved for batch files. Checker exclusions, Markdown HTML rules, spelling scope, ignore patterns, host-tool declaration, and coverage package version were updated.

Library and tests

Layer / File(s)	Summary
StringHistory implementation and coverage Utilities/StringHistory.cs, UtilitiesTests/StringHistoryTests.cs	Added configurable first-line and last-line retention, bounded rolling behavior, validation, read-only storage, and newline rendering.
Existing source and test normalization Utilities/*.cs, UtilitiesTests/*.cs, Sandbox/*, project files, workspace files	Existing implementations, APIs, tests, assertions, and project settings were reformatted or normalized without stated behavioral changes.

Estimated code review effort: 3 (Moderate) | ~25 minutes

Merge Risk:🟠 High · up to 8af98

The promoted tree contains a malformed .NET tool manifest that blocks tool restoration, mutable history limits that can violate retention or throw on invalid input, and automation/workspace controls that can permit unintended merges or primary-checkout writes. These correctness and security risks make the PR not ready to merge until fixed.

High-Level Assessment

The following are alternative approaches to this PR:

1. Keep reusable workflows in-repo

• ➕ Workflow changes can be exercised directly from the repository head.
• ➕ The repository remains independent of hub availability.
• ➖ Duplicates generic orchestration across the fleet.
• ➖ Requires repeated synchronization and allows stale CI copies to report false conformance.

2. Resolve the promotion directly on develop

• ➕ Would avoid a temporary promotion branch.
• ➕ Keeps the promotion head on the normal integration branch.
• ➖ Develop's linear-history and pull-request rules prevent the required merge resolution.
• ➖ A back-merge would violate the forward-only branch model.

Recommendation: Use the current throwaway branch from main, resolve verified conflicts to develop's tree, and consume generic CI through commit-pinned hub workflows. This preserves branch protections, produces the proven develop-equivalent tree, and removes duplicated workflow maintenance while retaining repository-owned caller configuration.

🐞 Bugs (0)📘 Rule violations (0)📜 Skill insights (0)

1. README edits mixed with normalization✗ Dismissed📘 Rule violation⚙ Maintainability

Description

README.md combines a whole-file CRLF-to-LF rewrite with substantive additions including a table of
contents and new sections. This prevents the normalization from being reviewed as an isolated
EOL-only change.

Code

README.md[R39-42]

+## Table of Contents++- [Build and Distribution](#build-and-distribution)+ - [Build Status](#build-status)

Relevance

●●● Strong

The finding identifies substantive README additions in a file also rewritten for EOL normalization,
directly violating the isolation rule.

ⓘ Recommendations generated based on similar findings in past PRs

Evidence

Rule 2826678 allows EOL normalization only when visible content is unchanged. The patch replaces the
full 84-line base file with a 154-line file, and the cited newly added table of contents is a
substantive content change.

2. Comments cite requirement identifiers✗ Dismissed📘 Rule violation⚙ Maintainability

Description

The workflow comments cite D1.1, D1.4, S2, and S3 while explaining the job. These
governance-style identifiers are not change-local implementation context and violate the restriction
on policy or standard references in code-review comments.

Code

.github/workflows/test-pull-request.yml[R27-29]

+ # This repository builds one release target, the NuGet package (D1.1).+ # The filter 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.+ # Naming the inputs rather than excluding workflow files means a documentation-only or workflow-only pull request skips the smoke build rather than packing the library for nothing (D1.4, and scenarios S2 and S3).

Relevance

●●● Strong

Explicit comment rule directly prohibits governance identifiers; removing those references is a
deterministic local edit.

ⓘ Recommendations generated based on similar findings in past PRs

Evidence

Rule 2826588 explicitly prohibits comments that cite governance documents, standards, or policy IDs.
The cited added comment block contains multiple such identifiers.

3. Comment references external hub✗ Dismissed📘 Rule violation⚙ Maintainability

Description

The new merge-bot comment refers to the hub and to every fleet repo, describing cross-repository
architecture rather than only the local workflow. The checklist disallows comments that name or
discuss another repository, service, or project.

Code

.github/workflows/merge-bot-pull-request.yml[R3-4]

+# Thin caller: the merge-bot is the hub's reusable merge-bot-task.yml, which every fleet repo reaches rather than carries.+# The trigger is pull_request_target so the called workflow resolves from the trusted base rather than the PR head, and no job checks out PR code.

Relevance

●●● Strong

Explicit repository rule directly prohibits external-repository discussion; removing the comment is
a straightforward local fix.

ⓘ Recommendations generated based on similar findings in past PRs

Evidence

Rule 2826588 restricts comments to the surrounding file and prohibits references to other
repositories, services, or projects. The cited added comment explicitly discusses the hub's reusable
task and fleet repositories.

4. Workflow embeds extensive rationale✗ Dismissed📘 Rule violation⚙ Maintainability

Description

The changes job is preceded by a multi-line architectural rationale covering release targets,
publisher inputs, and several requirement scenarios. Workflow guidance requires this high-level
rationale to be consolidated into a single-line top summary rather than scattered above jobs.

Code

.github/workflows/test-pull-request.yml[R27-29]

+ # This repository builds one release target, the NuGet package (D1.1).+ # The filter 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.+ # Naming the inputs rather than excluding workflow files means a documentation-only or workflow-only pull request skips the smoke build rather than packing the library for nothing (D1.4, and scenarios S2 and S3).

Relevance

●●● Strong

Explicit workflow-comment rule directly requires concise summaries instead of scattered multi-line
architectural rationale.

ⓘ Recommendations generated based on similar findings in past PRs

Evidence

Rule 2826632 disallows large top-level rationale comments scattered across workflow jobs. The cited
three-line block explains release architecture and multiple scenarios rather than a short local
implementation detail.

5. Package bump mixed with normalization✗ Dismissed📘 Rule violation⚙ Maintainability

Description

Directory.Packages.props is wholly rewritten for CRLF-to-LF normalization while also changing the
code-coverage package from 18.9.0 to 18.10.0. Mixing a substantive dependency edit into the
normalized file violates the required isolation of EOL-only changes.

Code

Directory.Packages.props[8]

+ <PackageVersion Include="Microsoft.Testing.Extensions.CodeCoverage" Version="18.10.0" />

Relevance

●●● Strong

The finding identifies a concrete token change inside an EOL-normalized file, directly violating the
stated isolation rule.

ⓘ Recommendations generated based on similar findings in past PRs

Evidence

Rule 2826678 requires an EOL-normalized file to contain no token changes. The diff removes and
re-adds all 16 lines while the cited declaration changes Microsoft.Testing.Extensions.CodeCoverage
from 18.9.0 to 18.10.0.

🔵 Needs a closer look

It combines broad CI/publish workflow rewiring (hub-hosted calls, permissions/secrets scoping) with large-scale repo normalization and retirements that warrants final human validation.

Pull request overview

Promotes the develop branch state into main by aligning repository configuration, documentation, tooling, and CI wiring with the hub-resynced setup (including LF normalization and hub-hosted reusable workflows).

Changes:

• Normalize/standardize repo files (formatting and LF line endings) and refresh solution/workspace metadata.
• Move CI orchestration to hub-hosted reusable workflows and retire repo-local workflow task implementations/config payloads.
• Add/refresh carried skills and governance/architecture documentation to match the current fleet model.

[ptr727]

Answering the two Qodo review-body findings here, since they carry no thread to resolve. Both also have inline threads, which are answered and resolved there.

"Comments cite requirement identifiers" (test-pull-request.yml, citing D1.1, D1.4, S2, S3). Declined. Those identifiers are defined in WORKFLOW.md, which this repository carries and which this pull request changes, so they are pointers into this repository's own CI contract rather than an external policy reference. D1.1 and D1.4 are the guarantees the changes job implements, and S2 and S3 are the scenarios in that same file's test-methodology table asserting that a documentation-only and a workflow-only pull request skip the smoke build. The reference caller stub this file is adopted from carries the same citations verbatim, including (D1.1) on the filter and (D1.5, D7.4) on the aggregator.

"Comment references external hub" (merge-bot-pull-request.yml). Half declined, half taken. The rule invoked governs carried template files and states its own boundary, that a repository's own content is outside it, and a workflow is repository-owned. The reference is also in the runnable body rather than only the prose, since the job is uses: ptr727/ProjectTemplate/.github/workflows/merge-bot-task.yml@f3b4cc9. The wording point is fair though: "which every fleet repo reaches rather than carries" describes other repositories, and this repository's file has no reason to. That reword goes to develop rather than here, because this promotion's tree is byte-identical to develop's and editing it would leave main ahead on that file, which is the drift this promotion exists to remove.

The remaining two Qodo findings from the first round, on mixing the package bump and the README rewrite with the line-ending normalization, are answered in their own threads: the line-endings rule permits a broader maintenance change to normalize alongside content edits when it is called out and the content is verified separately with git diff --ignore-cr-at-eol, and both conditions are met.

Inline comments:
In @.config/dotnet-tools.json:
- Line 19: Close the root JSON object in the dotnet-tools manifest after the
tools object so the document is valid JSON and dotnet tool restore can parse it
successfully.
In @.github/skills/drive-pr/SKILL.md:
- Around line 46-48: Update the drive skill’s authorization guidance so
answering the how-far question only selects the target and cannot authorize a
feature-to-develop squash merge. Require separate explicit confirmation naming
that merge action before step 4 proceeds, or enforce an authenticated
maintainer-only invocation boundary, while preserving the prohibition on
develop-to-main promotion and release dispatch authorization.
In @.github/skills/git-commit-conventions/SKILL.md:
- Around line 89-90: Update the PowerShell instructions around the git init and
commit command to declare PowerShell 7 or later as a prerequisite, or replace
the && chain with explicit exit-code checks so the commands remain compatible
with Windows PowerShell 5.1.
In
@.github/skills/operational-vs-release-workflow/references/branch-protection-and-promotion.md:
- Around line 35-38: Update the merge-resolution workflow after resolving
EOL-conflicted files with git checkout --theirs <file>: stage every
resolved path using git add or git rm, then complete the merge with git commit
or git merge --continue before opening the promotion PR.
In @.github/skills/repo-worktree/SKILL.md:
- Around line 141-142: Update gh-write-guard.py so
GH_WRITE_GUARD_ALLOW_PRIMARY_CHECKOUT bypasses protection only for the approved
standalone-clone fallback path, validating the target path before allowing the
mutation. Keep primary-checkout writes denied even when the session variable is
non-falsy, and preserve the existing fallback checkout behavior.
In @.vscode/tasks.json:
- Line 142: Update the four lint task definitions in tasks.json to invoke
scripts/docker_lint.py instead of direct docker run commands, preserving each
task’s lint purpose and arguments. Ensure they use the governed wrapper’s digest
resolution, read-only workspace mounts, disabled networking, and timeout
controls rather than :latest images and writable mounts.
In `@AUDIT.md`:
- Line 28: Update the prose in AUDIT.md to replace “afterwards” with “afterward”
near the Fleet Bootstrap guidance, and replace “all-drifts” with a clear phrase
such as “PR that addresses all drift classes” at the later occurrence.
In `@GOVERNANCE.md`:
- Line 221: Update the boolean-input guidance in GOVERNANCE.md (lines 221-221)
and .github/skills/workflow-ci-contract/SKILL.md (lines 27-27): use direct
Boolean checks through inputs.foo, and only compare against string values when
reading github.event.inputs.foo. Keep the documented workflow_call and
workflow_dispatch declarations accurate in both documents.
In `@OPERATIONS.md`:
- Around line 27-30: Update the Docker image references in the documented
validation commands, including the repeated commands around the actionlint and
editorconfig-checker entries, to use approved immutable digests instead of
mutable tags such as latest. Preserve each command’s existing arguments and
update digests deliberately when changing image versions.
In `@Utilities/StringHistory.cs`:
- Around line 84-90: Update MaxFirstLines and MaxLastLines so limits cannot be
negative and changing them preserves retention immediately: either make the
properties initialization-only or, in their setters, re-partition _stringList
and synchronize _firstLines and _lastLines. Ensure subsequent appends never
retain more than the configured first and last limits.
- Line 82: Update the limit documentation near AppendLine and the corresponding
constructor parameter to describe one-sided zero behavior accurately: when one
limit is zero and the other is positive, retain entries only according to the
positive limit on that side, rather than stating that zero means no limit.

Promotes the hub resync (#451) to main.

Why this is a promote/ branch rather than develop itself

main carried its own copies of work develop had done independently: the Microsoft.Testing.Platform migration (#448 against #447) and an AwesomeAssertions bump (#450 against #449). Combined with the CRLF-to-LF renormalization, develop -> main conflicts on seven paths, and develop's required_linear_history plus its PR ruleset forbid resolving them on develop. This is the documented remedy: resolve on a throwaway branch off main, then open that into main.

The resolution is provably exactly develop

Every conflict was resolved to develop's side, and the result is byte-identical to develop's tree:

merged tree 503594305d3fe69900452453c806dedded8f1243
develop tree 503594305d3fe69900452453c806dedded8f1243

Each was confirmed lossless before develop was taken, per the documented check:

Path	Why taking develop drops nothing
global.json	Content-identical modulo EOL. main added it CRLF, develop renormalized it.
UtilitiesTests/UtilitiesTests.csproj	Content-identical modulo EOL.
UtilitiesTests/ExtensionsTests.cs	Content-identical modulo EOL.
Directory.Packages.props	Differs in one line, the coverage extension, where develop is the newer 18.10.0 against main's 18.9.0.
Utilities.slnx	main's extra entries are a duplicate dependabot.yml, a Data/ folder naming three files this repository does not contain, and the two workflow tasks develop deleted because the hub now hosts them. Verified each path is absent on develop, and that dependabot.yml is still listed there under GitHub Actions.
.github/workflows/build-release-task.yml	Deleted on develop per its retire disposition.
.github/workflows/validate-task.yml	Deleted on develop, which now calls the hub-hosted validator by pin.

Verification

Run against this branch's tree, not inferred from #451:

dotnet build 0 warnings, 0 errors
dotnet csharpier check . 43 files, clean
dotnet format style --verify-no-changes clean
dotnet test (MTP + coverage) 183/183 passed
markdownlint-cli2 '**/*.md' 48 files, 0 issues
actionlint clean
editorconfig-checker clean
repo_gate.py eol, eol-coverage, sha-pin all clean
prose_lint.py --diff origin/main clean

Merging

The head is promote/develop-to-main, not develop, so the delete-develop trap does not apply here. Merge with a merge commit rather than a squash, per the main ruleset.

📝 Walkthrough

Walkthrough

The pull request centralizes repository governance and agent procedures, adds fleet Skills and documentation, updates GitHub workflow composition, normalizes line endings and formatting, upgrades code coverage tooling, and adds the public StringHistory class with tests.

Changes

Repository governance and Skills

Layer / File(s)	Summary
Centralized governance and agent procedures AGENTS.md, GOVERNANCE.md, CODESTYLE.md, AUDIT.md, ARCHITECTURE.md, OPERATIONS.md, .github/copilot-instructions.md	Repository rules now use concise indexes and shared governance documents. Agent conduct, auditing, resynchronization, worktrees, review, release, and contribution procedures are defined in Skills.
Language, workflow, and documentation Skills .github/skills/*	New Skills define .NET, Python, Shell, workflow, Git, review, release, repository, and documentation procedures with supporting references.
Repository documentation and entry points README.md, CLAUDE.md, HISTORY.md, Utilities.slnx	Project documentation, release history, Claude entry-point guidance, and solution-item organization were updated.

Workflow and repository configuration

Layer / File(s)	Summary
Pinned validation and release workflows .github/workflows/test-pull-request.yml, .github/workflows/publish-release.yml, .github/workflows/merge-bot-pull-request.yml	Workflows now call pinned external reusable tasks, use scoped permissions and secrets, detect release-relevant changes, conditionally run smoke builds, and aggregate skipped jobs correctly.
Removed local reusable workflows .github/workflows/build-release-task.yml, .github/workflows/publish-plan-task.yml, .github/workflows/validate-task.yml	The local release, publish-plan, and validation workflow interfaces were deleted.
Formatting, line endings, and tooling configuration .editorconfig, .gitattributes, .editorconfig-checker.json, .markdownlint-cli2.jsonc, cspell.json, .gitignore, .husky/*, Directory.Packages.props, host-tools.json	LF is now the default with CRLF reserved for batch files. Checker exclusions, Markdown HTML rules, spelling scope, ignore patterns, host-tool declaration, and coverage package version were updated.

Library and tests

Layer / File(s)	Summary
StringHistory implementation and coverage Utilities/StringHistory.cs, UtilitiesTests/StringHistoryTests.cs	Added configurable first-line and last-line retention, bounded rolling behavior, validation, read-only storage, and newline rendering.
Existing source and test normalization Utilities/*.cs, UtilitiesTests/*.cs, Sandbox/*, project files, workspace files	Existing implementations, APIs, tests, assertions, and project settings were reformatted or normalized without stated behavioral changes.

Estimated code review effort: 3 (Moderate) | ~25 minutes

Merge Risk:🟠 High · up to 8af98

The promoted tree contains a malformed .NET tool manifest that blocks tool restoration, mutable history limits that can violate retention or throw on invalid input, and automation/workspace controls that can permit unintended merges or primary-checkout writes. These correctness and security risks make the PR not ready to merge until fixed.

High-Level Assessment

The following are alternative approaches to this PR:

1. Keep reusable workflows in-repo

• ➕ Workflow changes can be exercised directly from the repository head.
• ➕ The repository remains independent of hub availability.
• ➖ Duplicates generic orchestration across the fleet.
• ➖ Requires repeated synchronization and allows stale CI copies to report false conformance.

2. Resolve the promotion directly on develop

• ➕ Would avoid a temporary promotion branch.
• ➕ Keeps the promotion head on the normal integration branch.
• ➖ Develop's linear-history and pull-request rules prevent the required merge resolution.
• ➖ A back-merge would violate the forward-only branch model.

Recommendation: Use the current throwaway branch from main, resolve verified conflicts to develop's tree, and consume generic CI through commit-pinned hub workflows. This preserves branch protections, produces the proven develop-equivalent tree, and removes duplicated workflow maintenance while retaining repository-owned caller configuration.

🐞 Bugs (0)📘 Rule violations (0)📜 Skill insights (0)

1. README edits mixed with normalization✗ Dismissed📘 Rule violation⚙ Maintainability

Description

README.md combines a whole-file CRLF-to-LF rewrite with substantive additions including a table of
contents and new sections. This prevents the normalization from being reviewed as an isolated
EOL-only change.

Code

README.md[R39-42]

+## Table of Contents++- [Build and Distribution](#build-and-distribution)+ - [Build Status](#build-status)

Relevance

●●● Strong

The finding identifies substantive README additions in a file also rewritten for EOL normalization,
directly violating the isolation rule.

ⓘ Recommendations generated based on similar findings in past PRs

Evidence

Rule 2826678 allows EOL normalization only when visible content is unchanged. The patch replaces the
full 84-line base file with a 154-line file, and the cited newly added table of contents is a
substantive content change.

2. Comments cite requirement identifiers✗ Dismissed📘 Rule violation⚙ Maintainability

Description

The workflow comments cite D1.1, D1.4, S2, and S3 while explaining the job. These
governance-style identifiers are not change-local implementation context and violate the restriction
on policy or standard references in code-review comments.

Code

.github/workflows/test-pull-request.yml[R27-29]

+ # This repository builds one release target, the NuGet package (D1.1).+ # The filter 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.+ # Naming the inputs rather than excluding workflow files means a documentation-only or workflow-only pull request skips the smoke build rather than packing the library for nothing (D1.4, and scenarios S2 and S3).

Relevance

●●● Strong

Explicit comment rule directly prohibits governance identifiers; removing those references is a
deterministic local edit.

3. Comment references external hub✗ Dismissed📘 Rule violation⚙ Maintainability

Description

The new merge-bot comment refers to the hub and to every fleet repo, describing cross-repository
architecture rather than only the local workflow. The checklist disallows comments that name or
discuss another repository, service, or project.

Code

.github/workflows/merge-bot-pull-request.yml[R3-4]

+# Thin caller: the merge-bot is the hub's reusable merge-bot-task.yml, which every fleet repo reaches rather than carries.+# The trigger is pull_request_target so the called workflow resolves from the trusted base rather than the PR head, and no job checks out PR code.

Relevance

●●● Strong

Explicit repository rule directly prohibits external-repository discussion; removing the comment is
a straightforward local fix.

ⓘ Recommendations generated based on similar findings in past PRs

Rule 2826588 restricts comments to the surrounding file and prohibits references to other
repositories, services, or projects. The cited added comment explicitly discusses the hub's reusable
task and fleet repositories.

4. Workflow embeds extensive rationale✗ Dismissed📘 Rule violation⚙ Maintainability

Description

The changes job is preceded by a multi-line architectural rationale covering release targets,
publisher inputs, and several requirement scenarios. Workflow guidance requires this high-level
rationale to be consolidated into a single-line top summary rather than scattered above jobs.

Code

+ # This repository builds one release target, the NuGet package (D1.1).+ # The filter 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.+ # Naming the inputs rather than excluding workflow files means a documentation-only or workflow-only pull request skips the smoke build rather than packing the library for nothing (D1.4, and scenarios S2 and S3).

Explicit workflow-comment rule directly requires concise summaries instead of scattered multi-line
architectural rationale.

5. Package bump mixed with normalization✗ Dismissed📘 Rule violation⚙ Maintainability

Description

Directory.Packages.props is wholly rewritten for CRLF-to-LF normalization while also changing the
code-coverage package from 18.9.0 to 18.10.0. Mixing a substantive dependency edit into the
normalized file violates the required isolation of EOL-only changes.

Code

Directory.Packages.props[8]

+ <PackageVersion Include="Microsoft.Testing.Extensions.CodeCoverage" Version="18.10.0" />

Relevance

●●● Strong

The finding identifies a concrete token change inside an EOL-normalized file, directly violating the
stated isolation rule.

ⓘ Recommendations generated based on similar findings in past PRs

Evidence

Rule 2826678 requires an EOL-normalized file to contain no token changes. The diff removes and
re-adds all 16 lines while the cited declaration changes Microsoft.Testing.Extensions.CodeCoverage

🔵 Needs a closer look

It combines broad CI/publish workflow rewiring (hub-hosted calls, permissions/secrets scoping) with large-scale repo normalization and retirements that warrants final human validation.

Pull request overview

Promotes the develop branch state into main by aligning repository configuration, documentation, tooling, and CI wiring with the hub-resynced setup (including LF normalization and hub-hosted reusable workflows).

Changes:

• Normalize/standardize repo files (formatting and LF line endings) and refresh solution/workspace metadata.
• Move CI orchestration to hub-hosted reusable workflows and retire repo-local workflow task implementations/config payloads.
• Add/refresh carried skills and governance/architecture documentation to match the current fleet model.

[ptr727]

Answering the two Qodo review-body findings here, since they carry no thread to resolve. Both also have inline threads, which are answered and resolved there.

"Comments cite requirement identifiers" (test-pull-request.yml, citing D1.1, D1.4, S2, S3). Declined. Those identifiers are defined in WORKFLOW.md, which this repository carries and which this pull request changes, so they are pointers into this repository's own CI contract rather than an external policy reference. D1.1 and D1.4 are the guarantees the changes job implements, and S2 and S3 are the scenarios in that same file's test-methodology table asserting that a documentation-only and a workflow-only pull request skip the smoke build. The reference caller stub this file is adopted from carries the same citations verbatim, including (D1.1) on the filter and (D1.5, D7.4) on the aggregator.

"Comment references external hub" (merge-bot-pull-request.yml). Half declined, half taken. The rule invoked governs carried template files and states its own boundary, that a repository's own content is outside it, and a workflow is repository-owned. The reference is also in the runnable body rather than only the prose, since the job is uses: ptr727/ProjectTemplate/.github/workflows/merge-bot-task.yml@f3b4cc9. The wording point is fair though: "which every fleet repo reaches rather than carries" describes other repositories, and this repository's file has no reason to. That reword goes to develop rather than here, because this promotion's tree is byte-identical to develop's and editing it would leave main ahead on that file, which is the drift this promotion exists to remove.

The remaining two Qodo findings from the first round, on mixing the package bump and the README rewrite with the line-ending normalization, are answered in their own threads: the line-endings rule permits a broader maintenance change to normalize alongside content edits when it is called out and the content is verified separately with git diff --ignore-cr-at-eol, and both conditions are met.

Inline comments:
In @.config/dotnet-tools.json:
- Line 19: Close the root JSON object in the dotnet-tools manifest after the
tools object so the document is valid JSON and dotnet tool restore can parse it
successfully.
In @.github/skills/drive-pr/SKILL.md:
- Around line 46-48: Update the drive skill’s authorization guidance so
answering the how-far question only selects the target and cannot authorize a
feature-to-develop squash merge. Require separate explicit confirmation naming
that merge action before step 4 proceeds, or enforce an authenticated
maintainer-only invocation boundary, while preserving the prohibition on
develop-to-main promotion and release dispatch authorization.
In @.github/skills/git-commit-conventions/SKILL.md:
- Around line 89-90: Update the PowerShell instructions around the git init and
commit command to declare PowerShell 7 or later as a prerequisite, or replace
the && chain with explicit exit-code checks so the commands remain compatible
with Windows PowerShell 5.1.
In
@.github/skills/operational-vs-release-workflow/references/branch-protection-and-promotion.md:
- Around line 35-38: Update the merge-resolution workflow after resolving
EOL-conflicted files with git checkout --theirs <file>: stage every
resolved path using git add or git rm, then complete the merge with git commit
or git merge --continue before opening the promotion PR.
In @.github/skills/repo-worktree/SKILL.md:
- Around line 141-142: Update gh-write-guard.py so
GH_WRITE_GUARD_ALLOW_PRIMARY_CHECKOUT bypasses protection only for the approved
standalone-clone fallback path, validating the target path before allowing the
mutation. Keep primary-checkout writes denied even when the session variable is
non-falsy, and preserve the existing fallback checkout behavior.
In @.vscode/tasks.json:
- Line 142: Update the four lint task definitions in tasks.json to invoke
scripts/docker_lint.py instead of direct docker run commands, preserving each
task’s lint purpose and arguments. Ensure they use the governed wrapper’s digest
resolution, read-only workspace mounts, disabled networking, and timeout
controls rather than :latest images and writable mounts.
In `@AUDIT.md`:
- Line 28: Update the prose in AUDIT.md to replace “afterwards” with “afterward”
near the Fleet Bootstrap guidance, and replace “all-drifts” with a clear phrase
such as “PR that addresses all drift classes” at the later occurrence.
In `@GOVERNANCE.md`:
- Line 221: Update the boolean-input guidance in GOVERNANCE.md (lines 221-221)
and .github/skills/workflow-ci-contract/SKILL.md (lines 27-27): use direct
Boolean checks through inputs.foo, and only compare against string values when
reading github.event.inputs.foo. Keep the documented workflow_call and
workflow_dispatch declarations accurate in both documents.
In `@OPERATIONS.md`:
- Around line 27-30: Update the Docker image references in the documented
validation commands, including the repeated commands around the actionlint and
editorconfig-checker entries, to use approved immutable digests instead of
mutable tags such as latest. Preserve each command’s existing arguments and
update digests deliberately when changing image versions.
In `@Utilities/StringHistory.cs`:
- Around line 84-90: Update MaxFirstLines and MaxLastLines so limits cannot be
negative and changing them preserves retention immediately: either make the
properties initialization-only or, in their setters, re-partition _stringList
and synchronize _firstLines and _lastLines. Ensure subsequent appends never
retain more than the configured first and last limits.
- Line 82: Update the limit documentation near AppendLine and the corresponding
constructor parameter to describe one-sided zero behavior accurately: when one
limit is zero and the other is positive, retain entries only according to the
positive limit on that side, rather than stating that zero means no limit.

Promotes the hub resync (#451) to main.

Why this is a promote/ branch rather than develop itself

main carried its own copies of work develop had done independently: the Microsoft.Testing.Platform migration (#448 against #447) and an AwesomeAssertions bump (#450 against #449). Combined with the CRLF-to-LF renormalization, develop -> main conflicts on seven paths, and develop's required_linear_history plus its PR ruleset forbid resolving them on develop. This is the documented remedy: resolve on a throwaway branch off main, then open that into main.

The resolution is provably exactly develop

Every conflict was resolved to develop's side, and the result is byte-identical to develop's tree:

merged tree 503594305d3fe69900452453c806dedded8f1243
develop tree 503594305d3fe69900452453c806dedded8f1243

Each was confirmed lossless before develop was taken, per the documented check:

Path	Why taking develop drops nothing
global.json	Content-identical modulo EOL. main added it CRLF, develop renormalized it.
UtilitiesTests/UtilitiesTests.csproj	Content-identical modulo EOL.
UtilitiesTests/ExtensionsTests.cs	Content-identical modulo EOL.
Directory.Packages.props	Differs in one line, the coverage extension, where develop is the newer 18.10.0 against main's 18.9.0.
Utilities.slnx	main's extra entries are a duplicate dependabot.yml, a Data/ folder naming three files this repository does not contain, and the two workflow tasks develop deleted because the hub now hosts them. Verified each path is absent on develop, and that dependabot.yml is still listed there under GitHub Actions.
.github/workflows/build-release-task.yml	Deleted on develop per its retire disposition.
.github/workflows/validate-task.yml	Deleted on develop, which now calls the hub-hosted validator by pin.

Verification

Run against this branch's tree, not inferred from #451:

dotnet build 0 warnings, 0 errors
dotnet csharpier check . 43 files, clean
dotnet format style --verify-no-changes clean
dotnet test (MTP + coverage) 183/183 passed
markdownlint-cli2 '**/*.md' 48 files, 0 issues
actionlint clean
editorconfig-checker clean
repo_gate.py eol, eol-coverage, sha-pin all clean
prose_lint.py --diff origin/main clean

Merging

The head is promote/develop-to-main, not develop, so the delete-develop trap does not apply here. Merge with a merge commit rather than a squash, per the main ruleset.

📝 Walkthrough

Walkthrough

The pull request centralizes repository governance and agent procedures, adds fleet Skills and documentation, updates GitHub workflow composition, normalizes line endings and formatting, upgrades code coverage tooling, and adds the public StringHistory class with tests.

Changes

Repository governance and Skills

Layer / File(s)	Summary
Centralized governance and agent procedures AGENTS.md, GOVERNANCE.md, CODESTYLE.md, AUDIT.md, ARCHITECTURE.md, OPERATIONS.md, .github/copilot-instructions.md	Repository rules now use concise indexes and shared governance documents. Agent conduct, auditing, resynchronization, worktrees, review, release, and contribution procedures are defined in Skills.
Language, workflow, and documentation Skills .github/skills/*	New Skills define .NET, Python, Shell, workflow, Git, review, release, repository, and documentation procedures with supporting references.
Repository documentation and entry points README.md, CLAUDE.md, HISTORY.md, Utilities.slnx	Project documentation, release history, Claude entry-point guidance, and solution-item organization were updated.

Workflow and repository configuration

Layer / File(s)	Summary
Pinned validation and release workflows .github/workflows/test-pull-request.yml, .github/workflows/publish-release.yml, .github/workflows/merge-bot-pull-request.yml	Workflows now call pinned external reusable tasks, use scoped permissions and secrets, detect release-relevant changes, conditionally run smoke builds, and aggregate skipped jobs correctly.
Removed local reusable workflows .github/workflows/build-release-task.yml, .github/workflows/publish-plan-task.yml, .github/workflows/validate-task.yml	The local release, publish-plan, and validation workflow interfaces were deleted.
Formatting, line endings, and tooling configuration .editorconfig, .gitattributes, .editorconfig-checker.json, .markdownlint-cli2.jsonc, cspell.json, .gitignore, .husky/*, Directory.Packages.props, host-tools.json	LF is now the default with CRLF reserved for batch files. Checker exclusions, Markdown HTML rules, spelling scope, ignore patterns, host-tool declaration, and coverage package version were updated.

Library and tests

Layer / File(s)	Summary
StringHistory implementation and coverage Utilities/StringHistory.cs, UtilitiesTests/StringHistoryTests.cs	Added configurable first-line and last-line retention, bounded rolling behavior, validation, read-only storage, and newline rendering.
Existing source and test normalization Utilities/*.cs, UtilitiesTests/*.cs, Sandbox/*, project files, workspace files	Existing implementations, APIs, tests, assertions, and project settings were reformatted or normalized without stated behavioral changes.

Estimated code review effort: 3 (Moderate) | ~25 minutes

Merge Risk:🟠 High · up to 8af98

The promoted tree contains a malformed .NET tool manifest that blocks tool restoration, mutable history limits that can violate retention or throw on invalid input, and automation/workspace controls that can permit unintended merges or primary-checkout writes. These correctness and security risks make the PR not ready to merge until fixed.

High-Level Assessment

The following are alternative approaches to this PR:

1. Keep reusable workflows in-repo

• ➕ Workflow changes can be exercised directly from the repository head.
• ➕ The repository remains independent of hub availability.
• ➖ Duplicates generic orchestration across the fleet.
• ➖ Requires repeated synchronization and allows stale CI copies to report false conformance.

2. Resolve the promotion directly on develop

• ➕ Would avoid a temporary promotion branch.
• ➕ Keeps the promotion head on the normal integration branch.
• ➖ Develop's linear-history and pull-request rules prevent the required merge resolution.
• ➖ A back-merge would violate the forward-only branch model.

Recommendation: Use the current throwaway branch from main, resolve verified conflicts to develop's tree, and consume generic CI through commit-pinned hub workflows. This preserves branch protections, produces the proven develop-equivalent tree, and removes duplicated workflow maintenance while retaining repository-owned caller configuration.

1. README edits mixed with normalization✗ Dismissed📘 Rule violation⚙ Maintainability

Description

README.md combines a whole-file CRLF-to-LF rewrite with substantive additions including a table of
contents and new sections. This prevents the normalization from being reviewed as an isolated
EOL-only change.

Code

README.md[R39-42]

+## Table of Contents++- [Build and Distribution](#build-and-distribution)+ - [Build Status](#build-status)

Relevance

●●● Strong

The finding identifies substantive README additions in a file also rewritten for EOL normalization,
directly violating the isolation rule.

ⓘ Recommendations generated based on similar findings in past PRs

Evidence

Rule 2826678 allows EOL normalization only when visible content is unchanged. The patch replaces the
full 84-line base file with a 154-line file, and the cited newly added table of contents is a
substantive content change.

2. Comments cite requirement identifiers✗ Dismissed📘 Rule violation⚙ Maintainability

Description

The workflow comments cite D1.1, D1.4, S2, and S3 while explaining the job. These
governance-style identifiers are not change-local implementation context and violate the restriction
on policy or standard references in code-review comments.

Code

.github/workflows/test-pull-request.yml[R27-29]

+ # This repository builds one release target, the NuGet package (D1.1).+ # The filter 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.+ # Naming the inputs rather than excluding workflow files means a documentation-only or workflow-only pull request skips the smoke build rather than packing the library for nothing (D1.4, and scenarios S2 and S3).

Relevance

●●● Strong

Explicit comment rule directly prohibits governance identifiers; removing those references is a
deterministic local edit.

ⓘ Recommendations generated based on similar findings in past PRs

Evidence

Rule 2826588 explicitly prohibits comments that cite governance documents, standards, or policy IDs.
The cited added comment block contains multiple such identifiers.

3. Comment references external hub✗ Dismissed📘 Rule violation⚙ Maintainability

Description

The new merge-bot comment refers to the hub and to every fleet repo, describing cross-repository
architecture rather than only the local workflow. The checklist disallows comments that name or
discuss another repository, service, or project.

Code

.github/workflows/merge-bot-pull-request.yml[R3-4]

+# Thin caller: the merge-bot is the hub's reusable merge-bot-task.yml, which every fleet repo reaches rather than carries.+# The trigger is pull_request_target so the called workflow resolves from the trusted base rather than the PR head, and no job checks out PR code.

Relevance

●●● Strong

Explicit repository rule directly prohibits external-repository discussion; removing the comment is
a straightforward local fix.

ⓘ Recommendations generated based on similar findings in past PRs

Evidence

Rule 2826588 restricts comments to the surrounding file and prohibits references to other
repositories, services, or projects. The cited added comment explicitly discusses the hub's reusable
task and fleet repositories.

4. Workflow embeds extensive rationale✗ Dismissed📘 Rule violation⚙ Maintainability

Description

The changes job is preceded by a multi-line architectural rationale covering release targets,
publisher inputs, and several requirement scenarios. Workflow guidance requires this high-level
rationale to be consolidated into a single-line top summary rather than scattered above jobs.

+ # This repository builds one release target, the NuGet package (D1.1).+ # The filter 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.+ # Naming the inputs rather than excluding workflow files means a documentation-only or workflow-only pull request skips the smoke build rather than packing the library for nothing (D1.4, and scenarios S2 and S3).

Explicit workflow-comment rule directly requires concise summaries instead of scattered multi-line
architectural rationale.

The finding identifies a concrete token change inside an EOL-normalized file, directly violating the
stated isolation rule.

ⓘ Recommendations generated based on similar findings in past PRs

Evidence

Rule 2826678 requires an EOL-normalized file to contain no token changes. The diff removes and
re-adds all 16 lines while the cited declaration changes Microsoft.Testing.Extensions.CodeCoverage

🔵 Needs a closer look

It combines broad CI/publish workflow rewiring (hub-hosted calls, permissions/secrets scoping) with large-scale repo normalization and retirements that warrants final human validation.

Pull request overview

Promotes the develop branch state into main by aligning repository configuration, documentation, tooling, and CI wiring with the hub-resynced setup (including LF normalization and hub-hosted reusable workflows).

Changes:

• Normalize/standardize repo files (formatting and LF line endings) and refresh solution/workspace metadata.
• Move CI orchestration to hub-hosted reusable workflows and retire repo-local workflow task implementations/config payloads.
• Add/refresh carried skills and governance/architecture documentation to match the current fleet model.

[ptr727]

Answering the two Qodo review-body findings here, since they carry no thread to resolve. Both also have inline threads, which are answered and resolved there.

"Comments cite requirement identifiers" (test-pull-request.yml, citing D1.1, D1.4, S2, S3). Declined. Those identifiers are defined in WORKFLOW.md, which this repository carries and which this pull request changes, so they are pointers into this repository's own CI contract rather than an external policy reference. D1.1 and D1.4 are the guarantees the changes job implements, and S2 and S3 are the scenarios in that same file's test-methodology table asserting that a documentation-only and a workflow-only pull request skip the smoke build. The reference caller stub this file is adopted from carries the same citations verbatim, including (D1.1) on the filter and (D1.5, D7.4) on the aggregator.

"Comment references external hub" (merge-bot-pull-request.yml). Half declined, half taken. The rule invoked governs carried template files and states its own boundary, that a repository's own content is outside it, and a workflow is repository-owned. The reference is also in the runnable body rather than only the prose, since the job is uses: ptr727/ProjectTemplate/.github/workflows/merge-bot-task.yml@f3b4cc9. The wording point is fair though: "which every fleet repo reaches rather than carries" describes other repositories, and this repository's file has no reason to. That reword goes to develop rather than here, because this promotion's tree is byte-identical to develop's and editing it would leave main ahead on that file, which is the drift this promotion exists to remove.

The remaining two Qodo findings from the first round, on mixing the package bump and the README rewrite with the line-ending normalization, are answered in their own threads: the line-endings rule permits a broader maintenance change to normalize alongside content edits when it is called out and the content is verified separately with git diff --ignore-cr-at-eol, and both conditions are met.

Inline comments:
In @.config/dotnet-tools.json:
- Line 19: Close the root JSON object in the dotnet-tools manifest after the
tools object so the document is valid JSON and dotnet tool restore can parse it
successfully.
In @.github/skills/drive-pr/SKILL.md:
- Around line 46-48: Update the drive skill’s authorization guidance so
answering the how-far question only selects the target and cannot authorize a
feature-to-develop squash merge. Require separate explicit confirmation naming
that merge action before step 4 proceeds, or enforce an authenticated
maintainer-only invocation boundary, while preserving the prohibition on
develop-to-main promotion and release dispatch authorization.
In @.github/skills/git-commit-conventions/SKILL.md:
- Around line 89-90: Update the PowerShell instructions around the git init and
commit command to declare PowerShell 7 or later as a prerequisite, or replace
the && chain with explicit exit-code checks so the commands remain compatible
with Windows PowerShell 5.1.
In
@.github/skills/operational-vs-release-workflow/references/branch-protection-and-promotion.md:
- Around line 35-38: Update the merge-resolution workflow after resolving
EOL-conflicted files with git checkout --theirs <file>: stage every
resolved path using git add or git rm, then complete the merge with git commit
or git merge --continue before opening the promotion PR.
In @.github/skills/repo-worktree/SKILL.md:
- Around line 141-142: Update gh-write-guard.py so
GH_WRITE_GUARD_ALLOW_PRIMARY_CHECKOUT bypasses protection only for the approved
standalone-clone fallback path, validating the target path before allowing the
mutation. Keep primary-checkout writes denied even when the session variable is
non-falsy, and preserve the existing fallback checkout behavior.
In @.vscode/tasks.json:
- Line 142: Update the four lint task definitions in tasks.json to invoke
scripts/docker_lint.py instead of direct docker run commands, preserving each
task’s lint purpose and arguments. Ensure they use the governed wrapper’s digest
resolution, read-only workspace mounts, disabled networking, and timeout
controls rather than :latest images and writable mounts.
In `@AUDIT.md`:
- Line 28: Update the prose in AUDIT.md to replace “afterwards” with “afterward”
near the Fleet Bootstrap guidance, and replace “all-drifts” with a clear phrase
such as “PR that addresses all drift classes” at the later occurrence.
In `@GOVERNANCE.md`:
- Line 221: Update the boolean-input guidance in GOVERNANCE.md (lines 221-221)
and .github/skills/workflow-ci-contract/SKILL.md (lines 27-27): use direct
Boolean checks through inputs.foo, and only compare against string values when
reading github.event.inputs.foo. Keep the documented workflow_call and
workflow_dispatch declarations accurate in both documents.
In `@OPERATIONS.md`:
- Around line 27-30: Update the Docker image references in the documented
validation commands, including the repeated commands around the actionlint and
editorconfig-checker entries, to use approved immutable digests instead of
mutable tags such as latest. Preserve each command’s existing arguments and
update digests deliberately when changing image versions.
In `@Utilities/StringHistory.cs`:
- Around line 84-90: Update MaxFirstLines and MaxLastLines so limits cannot be
negative and changing them preserves retention immediately: either make the
properties initialization-only or, in their setters, re-partition _stringList
and synchronize _firstLines and _lastLines. Ensure subsequent appends never
retain more than the configured first and last limits.
- Line 82: Update the limit documentation near AppendLine and the corresponding
constructor parameter to describe one-sided zero behavior accurately: when one
limit is zero and the other is positive, retain entries only according to the
positive limit on that side, rather than stating that zero means no limit.

Promotes the hub resync (#451) to main.

Why this is a promote/ branch rather than develop itself

main carried its own copies of work develop had done independently: the Microsoft.Testing.Platform migration (#448 against #447) and an AwesomeAssertions bump (#450 against #449). Combined with the CRLF-to-LF renormalization, develop -> main conflicts on seven paths, and develop's required_linear_history plus its PR ruleset forbid resolving them on develop. This is the documented remedy: resolve on a throwaway branch off main, then open that into main.

The resolution is provably exactly develop

Every conflict was resolved to develop's side, and the result is byte-identical to develop's tree:

merged tree 503594305d3fe69900452453c806dedded8f1243
develop tree 503594305d3fe69900452453c806dedded8f1243

Each was confirmed lossless before develop was taken, per the documented check:

Path	Why taking develop drops nothing
global.json	Content-identical modulo EOL. main added it CRLF, develop renormalized it.
UtilitiesTests/UtilitiesTests.csproj	Content-identical modulo EOL.
UtilitiesTests/ExtensionsTests.cs	Content-identical modulo EOL.
Directory.Packages.props	Differs in one line, the coverage extension, where develop is the newer 18.10.0 against main's 18.9.0.
Utilities.slnx	main's extra entries are a duplicate dependabot.yml, a Data/ folder naming three files this repository does not contain, and the two workflow tasks develop deleted because the hub now hosts them. Verified each path is absent on develop, and that dependabot.yml is still listed there under GitHub Actions.
.github/workflows/build-release-task.yml	Deleted on develop per its retire disposition.
.github/workflows/validate-task.yml	Deleted on develop, which now calls the hub-hosted validator by pin.

Verification

Run against this branch's tree, not inferred from #451:

dotnet build 0 warnings, 0 errors
dotnet csharpier check . 43 files, clean
dotnet format style --verify-no-changes clean
dotnet test (MTP + coverage) 183/183 passed
markdownlint-cli2 '**/*.md' 48 files, 0 issues
actionlint clean
editorconfig-checker clean
repo_gate.py eol, eol-coverage, sha-pin all clean
prose_lint.py --diff origin/main clean

Merging

The head is promote/develop-to-main, not develop, so the delete-develop trap does not apply here. Merge with a merge commit rather than a squash, per the main ruleset.

📝 Walkthrough

Walkthrough

The pull request centralizes repository governance and agent procedures, adds fleet Skills and documentation, updates GitHub workflow composition, normalizes line endings and formatting, upgrades code coverage tooling, and adds the public StringHistory class with tests.

Changes

Repository governance and Skills

Layer / File(s)	Summary
Centralized governance and agent procedures AGENTS.md, GOVERNANCE.md, CODESTYLE.md, AUDIT.md, ARCHITECTURE.md, OPERATIONS.md, .github/copilot-instructions.md	Repository rules now use concise indexes and shared governance documents. Agent conduct, auditing, resynchronization, worktrees, review, release, and contribution procedures are defined in Skills.
Language, workflow, and documentation Skills .github/skills/*	New Skills define .NET, Python, Shell, workflow, Git, review, release, repository, and documentation procedures with supporting references.
Repository documentation and entry points README.md, CLAUDE.md, HISTORY.md, Utilities.slnx	Project documentation, release history, Claude entry-point guidance, and solution-item organization were updated.

Workflow and repository configuration

Layer / File(s)	Summary
Pinned validation and release workflows .github/workflows/test-pull-request.yml, .github/workflows/publish-release.yml, .github/workflows/merge-bot-pull-request.yml	Workflows now call pinned external reusable tasks, use scoped permissions and secrets, detect release-relevant changes, conditionally run smoke builds, and aggregate skipped jobs correctly.
Removed local reusable workflows .github/workflows/build-release-task.yml, .github/workflows/publish-plan-task.yml, .github/workflows/validate-task.yml	The local release, publish-plan, and validation workflow interfaces were deleted.
Formatting, line endings, and tooling configuration .editorconfig, .gitattributes, .editorconfig-checker.json, .markdownlint-cli2.jsonc, cspell.json, .gitignore, .husky/*, Directory.Packages.props, host-tools.json	LF is now the default with CRLF reserved for batch files. Checker exclusions, Markdown HTML rules, spelling scope, ignore patterns, host-tool declaration, and coverage package version were updated.

Library and tests

Layer / File(s)	Summary
StringHistory implementation and coverage Utilities/StringHistory.cs, UtilitiesTests/StringHistoryTests.cs	Added configurable first-line and last-line retention, bounded rolling behavior, validation, read-only storage, and newline rendering.
Existing source and test normalization Utilities/*.cs, UtilitiesTests/*.cs, Sandbox/*, project files, workspace files	Existing implementations, APIs, tests, assertions, and project settings were reformatted or normalized without stated behavioral changes.

Estimated code review effort: 3 (Moderate) | ~25 minutes

Merge Risk:🟠 High · up to 8af98

The promoted tree contains a malformed .NET tool manifest that blocks tool restoration, mutable history limits that can violate retention or throw on invalid input, and automation/workspace controls that can permit unintended merges or primary-checkout writes. These correctness and security risks make the PR not ready to merge until fixed.

High-Level Assessment

The following are alternative approaches to this PR:

1. Keep reusable workflows in-repo

• ➕ Workflow changes can be exercised directly from the repository head.
• ➕ The repository remains independent of hub availability.
• ➖ Duplicates generic orchestration across the fleet.
• ➖ Requires repeated synchronization and allows stale CI copies to report false conformance.

2. Resolve the promotion directly on develop

• ➕ Would avoid a temporary promotion branch.
• ➕ Keeps the promotion head on the normal integration branch.
• ➖ Develop's linear-history and pull-request rules prevent the required merge resolution.
• ➖ A back-merge would violate the forward-only branch model.

Recommendation: Use the current throwaway branch from main, resolve verified conflicts to develop's tree, and consume generic CI through commit-pinned hub workflows. This preserves branch protections, produces the proven develop-equivalent tree, and removes duplicated workflow maintenance while retaining repository-owned caller configuration.

Code Review by Qodo

🐞 Bugs (0)📘 Rule violations (0)📜 Skill insights (0)

1. README edits mixed with normalization✗ Dismissed📘 Rule violation⚙ Maintainability

Description

README.md combines a whole-file CRLF-to-LF rewrite with substantive additions including a table of
contents and new sections. This prevents the normalization from being reviewed as an isolated
EOL-only change.

Code

README.md[R39-42]

+## Table of Contents++- [Build and Distribution](#build-and-distribution)+ - [Build Status](#build-status)

Relevance

●●● Strong

The finding identifies substantive README additions in a file also rewritten for EOL normalization,
directly violating the isolation rule.

ⓘ Recommendations generated based on similar findings in past PRs

Evidence

Rule 2826678 allows EOL normalization only when visible content is unchanged. The patch replaces the
full 84-line base file with a 154-line file, and the cited newly added table of contents is a
substantive content change.

## Issue description
Substantive README additions are mixed with whole-file EOL normalization.

2. Comments cite requirement identifiers✗ Dismissed📘 Rule violation⚙ Maintainability

Description

The workflow comments cite D1.1, D1.4, S2, and S3 while explaining the job. These
governance-style identifiers are not change-local implementation context and violate the restriction
on policy or standard references in code-review comments.

Code

.github/workflows/test-pull-request.yml[R27-29]

+ # This repository builds one release target, the NuGet package (D1.1).+ # The filter 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.+ # Naming the inputs rather than excluding workflow files means a documentation-only or workflow-only pull request skips the smoke build rather than packing the library for nothing (D1.4, and scenarios S2 and S3).

Relevance

●●● Strong

Explicit comment rule directly prohibits governance identifiers; removing those references is a
deterministic local edit.

ⓘ Recommendations generated based on similar findings in past PRs

Evidence

Rule 2826588 explicitly prohibits comments that cite governance documents, standards, or policy IDs.
The cited added comment block contains multiple such identifiers.

3. Comment references external hub✗ Dismissed📘 Rule violation⚙ Maintainability

Description

The new merge-bot comment refers to the hub and to every fleet repo, describing cross-repository
architecture rather than only the local workflow. The checklist disallows comments that name or
discuss another repository, service, or project.

Code

.github/workflows/merge-bot-pull-request.yml[R3-4]

+# Thin caller: the merge-bot is the hub's reusable merge-bot-task.yml, which every fleet repo reaches rather than carries.+# The trigger is pull_request_target so the called workflow resolves from the trusted base rather than the PR head, and no job checks out PR code.

Relevance

●●● Strong

Explicit repository rule directly prohibits external-repository discussion; removing the comment is
a straightforward local fix.

ⓘ Recommendations generated based on similar findings in past PRs

Evidence

Rule 2826588 restricts comments to the surrounding file and prohibits references to other
repositories, services, or projects. The cited added comment explicitly discusses the hub's reusable
task and fleet repositories.

4. Workflow embeds extensive rationale✗ Dismissed📘 Rule violation⚙ Maintainability

Description

The changes job is preceded by a multi-line architectural rationale covering release targets,
publisher inputs, and several requirement scenarios. Workflow guidance requires this high-level
rationale to be consolidated into a single-line top summary rather than scattered above jobs.

Code

.github/workflows/test-pull-request.yml[R27-29]

+ # This repository builds one release target, the NuGet package (D1.1).+ # The filter 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.+ # Naming the inputs rather than excluding workflow files means a documentation-only or workflow-only pull request skips the smoke build rather than packing the library for nothing (D1.4, and scenarios S2 and S3).

Relevance

●●● Strong

Explicit workflow-comment rule directly requires concise summaries instead of scattered multi-line
architectural rationale.

ⓘ Recommendations generated based on similar findings in past PRs

Evidence

Rule 2826632 disallows large top-level rationale comments scattered across workflow jobs. The cited
three-line block explains release architecture and multiple scenarios rather than a short local
implementation detail.

5. Package bump mixed with normalization✗ Dismissed📘 Rule violation⚙ Maintainability

Description

Directory.Packages.props is wholly rewritten for CRLF-to-LF normalization while also changing the
code-coverage package from 18.9.0 to 18.10.0. Mixing a substantive dependency edit into the
normalized file violates the required isolation of EOL-only changes.

Code

Directory.Packages.props[8]

+ <PackageVersion Include="Microsoft.Testing.Extensions.CodeCoverage" Version="18.10.0" />

Relevance

●●● Strong

The finding identifies a concrete token change inside an EOL-normalized file, directly violating the
stated isolation rule.

ⓘ Recommendations generated based on similar findings in past PRs

Evidence

Rule 2826678 requires an EOL-normalized file to contain no token changes. The diff removes and
re-adds all 16 lines while the cited declaration changes Microsoft.Testing.Extensions.CodeCoverage
from 18.9.0 to 18.10.0.

🔵 Needs a closer look

It combines broad CI/publish workflow rewiring (hub-hosted calls, permissions/secrets scoping) with large-scale repo normalization and retirements that warrants final human validation.

Pull request overview

Promotes the develop branch state into main by aligning repository configuration, documentation, tooling, and CI wiring with the hub-resynced setup (including LF normalization and hub-hosted reusable workflows).

Changes:

• Normalize/standardize repo files (formatting and LF line endings) and refresh solution/workspace metadata.
• Move CI orchestration to hub-hosted reusable workflows and retire repo-local workflow task implementations/config payloads.
• Add/refresh carried skills and governance/architecture documentation to match the current fleet model.

[ptr727]

Answering the two Qodo review-body findings here, since they carry no thread to resolve. Both also have inline threads, which are answered and resolved there.

"Comments cite requirement identifiers" (test-pull-request.yml, citing D1.1, D1.4, S2, S3). Declined. Those identifiers are defined in WORKFLOW.md, which this repository carries and which this pull request changes, so they are pointers into this repository's own CI contract rather than an external policy reference. D1.1 and D1.4 are the guarantees the changes job implements, and S2 and S3 are the scenarios in that same file's test-methodology table asserting that a documentation-only and a workflow-only pull request skip the smoke build. The reference caller stub this file is adopted from carries the same citations verbatim, including (D1.1) on the filter and (D1.5, D7.4) on the aggregator.

"Comment references external hub" (merge-bot-pull-request.yml). Half declined, half taken. The rule invoked governs carried template files and states its own boundary, that a repository's own content is outside it, and a workflow is repository-owned. The reference is also in the runnable body rather than only the prose, since the job is uses: ptr727/ProjectTemplate/.github/workflows/merge-bot-task.yml@f3b4cc9. The wording point is fair though: "which every fleet repo reaches rather than carries" describes other repositories, and this repository's file has no reason to. That reword goes to develop rather than here, because this promotion's tree is byte-identical to develop's and editing it would leave main ahead on that file, which is the drift this promotion exists to remove.

The remaining two Qodo findings from the first round, on mixing the package bump and the README rewrite with the line-ending normalization, are answered in their own threads: the line-endings rule permits a broader maintenance change to normalize alongside content edits when it is called out and the content is verified separately with git diff --ignore-cr-at-eol, and both conditions are met.

answering the how-far question only selects the target and cannot authorize a
feature-to-develop squash merge. Require separate explicit confirmation naming

- Around line 35-38: Update the merge-resolution workflow after resolving
EOL-conflicted files with git checkout --theirs <file>: stage every
resolved path using git add or git rm, then complete the merge with git commit
or git merge --continue before opening the promotion PR.
In @.github/skills/repo-worktree/SKILL.md:
- Around line 141-142: Update gh-write-guard.py so
GH_WRITE_GUARD_ALLOW_PRIMARY_CHECKOUT bypasses protection only for the approved
standalone-clone fallback path, validating the target path before allowing the
mutation. Keep primary-checkout writes denied even when the session variable is
non-falsy, and preserve the existing fallback checkout behavior.
In @.vscode/tasks.json:
- Line 142: Update the four lint task definitions in tasks.json to invoke
scripts/docker_lint.py instead of direct docker run commands, preserving each
task’s lint purpose and arguments. Ensure they use the governed wrapper’s digest
resolution, read-only workspace mounts, disabled networking, and timeout
controls rather than :latest images and writable mounts.
In `@AUDIT.md`:
- Line 28: Update the prose in AUDIT.md to replace “afterwards” with “afterward”
near the Fleet Bootstrap guidance, and replace “all-drifts” with a clear phrase
such as “PR that addresses all drift classes” at the later occurrence.
In `@GOVERNANCE.md`:
- Line 221: Update the boolean-input guidance in GOVERNANCE.md (lines 221-221)
and .github/skills/workflow-ci-contract/SKILL.md (lines 27-27): use direct
Boolean checks through inputs.foo, and only compare against string values when
reading github.event.inputs.foo. Keep the documented workflow_call and
workflow_dispatch declarations accurate in both documents.
In `@OPERATIONS.md`:
- Around line 27-30: Update the Docker image references in the documented
validation commands, including the repeated commands around the actionlint and
editorconfig-checker entries, to use approved immutable digests instead of
mutable tags such as latest. Preserve each command’s existing arguments and
update digests deliberately when changing image versions.
In `@Utilities/StringHistory.cs`:
- Around line 84-90: Update MaxFirstLines and MaxLastLines so limits cannot be
negative and changing them preserves retention immediately: either make the
properties initialization-only or, in their setters, re-partition _stringList
and synchronize _firstLines and _lastLines. Ensure subsequent appends never
retain more than the configured first and last limits.
- Line 82: Update the limit documentation near AppendLine and the corresponding
constructor parameter to describe one-sided zero behavior accurately: when one
limit is zero and the other is positive, retain entries only according to the
positive limit on that side, rather than stating that zero means no limit.

Promotes the hub resync (#451) to main.

Why this is a promote/ branch rather than develop itself

main carried its own copies of work develop had done independently: the Microsoft.Testing.Platform migration (#448 against #447) and an AwesomeAssertions bump (#450 against #449). Combined with the CRLF-to-LF renormalization, develop -> main conflicts on seven paths, and develop's required_linear_history plus its PR ruleset forbid resolving them on develop. This is the documented remedy: resolve on a throwaway branch off main, then open that into main.

The resolution is provably exactly develop

Every conflict was resolved to develop's side, and the result is byte-identical to develop's tree:

merged tree 503594305d3fe69900452453c806dedded8f1243
develop tree 503594305d3fe69900452453c806dedded8f1243

Each was confirmed lossless before develop was taken, per the documented check:

Path	Why taking develop drops nothing
global.json	Content-identical modulo EOL. main added it CRLF, develop renormalized it.
UtilitiesTests/UtilitiesTests.csproj	Content-identical modulo EOL.
UtilitiesTests/ExtensionsTests.cs	Content-identical modulo EOL.
Directory.Packages.props	Differs in one line, the coverage extension, where develop is the newer 18.10.0 against main's 18.9.0.
Utilities.slnx	main's extra entries are a duplicate dependabot.yml, a Data/ folder naming three files this repository does not contain, and the two workflow tasks develop deleted because the hub now hosts them. Verified each path is absent on develop, and that dependabot.yml is still listed there under GitHub Actions.
.github/workflows/build-release-task.yml	Deleted on develop per its retire disposition.
.github/workflows/validate-task.yml	Deleted on develop, which now calls the hub-hosted validator by pin.

Verification

Run against this branch's tree, not inferred from #451:

dotnet build 0 warnings, 0 errors
dotnet csharpier check . 43 files, clean
dotnet format style --verify-no-changes clean
dotnet test (MTP + coverage) 183/183 passed
markdownlint-cli2 '**/*.md' 48 files, 0 issues
actionlint clean
editorconfig-checker clean
repo_gate.py eol, eol-coverage, sha-pin all clean
prose_lint.py --diff origin/main clean

Merging

The head is promote/develop-to-main, not develop, so the delete-develop trap does not apply here. Merge with a merge commit rather than a squash, per the main ruleset.

Pinned validation and release workflows .github/workflows/test-pull-request.yml, .github/workflows/publish-release.yml, .github/workflows/merge-bot-pull-request.yml	Workflows now call pinned external reusable tasks, use scoped permissions and secrets, detect release-relevant changes, conditionally run smoke builds, and aggregate skipped jobs correctly.
Removed local reusable workflows .github/workflows/build-release-task.yml, .github/workflows/publish-plan-task.yml, .github/workflows/validate-task.yml	The local release, publish-plan, and validation workflow interfaces were deleted.
Formatting, line endings, and tooling configuration .editorconfig, .gitattributes, .editorconfig-checker.json, .markdownlint-cli2.jsonc, cspell.json, .gitignore, .husky/*, Directory.Packages.props, host-tools.json	LF is now the default with CRLF reserved for batch files. Checker exclusions, Markdown HTML rules, spelling scope, ignore patterns, host-tool declaration, and coverage package version were updated.

Library and tests

Layer / File(s)	Summary
StringHistory implementation and coverage Utilities/StringHistory.cs, UtilitiesTests/StringHistoryTests.cs	Added configurable first-line and last-line retention, bounded rolling behavior, validation, read-only storage, and newline rendering.
Existing source and test normalization Utilities/*.cs, UtilitiesTests/*.cs, Sandbox/*, project files, workspace files	Existing implementations, APIs, tests, assertions, and project settings were reformatted or normalized without stated behavioral changes.

Estimated code review effort: 3 (Moderate) | ~25 minutes

Merge Risk:🟠 High · up to 8af98

The promoted tree contains a malformed .NET tool manifest that blocks tool restoration, mutable history limits that can violate retention or throw on invalid input, and automation/workspace controls that can permit unintended merges or primary-checkout writes. These correctness and security risks make the PR not ready to merge until fixed.

High-Level Assessment

The following are alternative approaches to this PR:

1. Keep reusable workflows in-repo

• ➕ Workflow changes can be exercised directly from the repository head.
• ➕ The repository remains independent of hub availability.
• ➖ Duplicates generic orchestration across the fleet.
• ➖ Requires repeated synchronization and allows stale CI copies to report false conformance.

2. Resolve the promotion directly on develop

• ➕ Would avoid a temporary promotion branch.
• ➕ Keeps the promotion head on the normal integration branch.
• ➖ Develop's linear-history and pull-request rules prevent the required merge resolution.
• ➖ A back-merge would violate the forward-only branch model.

Recommendation: Use the current throwaway branch from main, resolve verified conflicts to develop's tree, and consume generic CI through commit-pinned hub workflows. This preserves branch protections, produces the proven develop-equivalent tree, and removes duplicated workflow maintenance while retaining repository-owned caller configuration.

1. README edits mixed with normalization✗ Dismissed📘 Rule violation⚙ Maintainability

Description

README.md combines a whole-file CRLF-to-LF rewrite with substantive additions including a table of
contents and new sections. This prevents the normalization from being reviewed as an isolated
EOL-only change.

Code

README.md[R39-42]

+## Table of Contents++- [Build and Distribution](#build-and-distribution)+ - [Build Status](#build-status)

Relevance

●●● Strong

The finding identifies substantive README additions in a file also rewritten for EOL normalization,
directly violating the isolation rule.

ⓘ Recommendations generated based on similar findings in past PRs

Evidence

Rule 2826678 allows EOL normalization only when visible content is unchanged. The patch replaces the
full 84-line base file with a 154-line file, and the cited newly added table of contents is a
substantive content change.

2. Comments cite requirement identifiers✗ Dismissed📘 Rule violation⚙ Maintainability

Description

The workflow comments cite D1.1, D1.4, S2, and S3 while explaining the job. These
governance-style identifiers are not change-local implementation context and violate the restriction
on policy or standard references in code-review comments.

Code

.github/workflows/test-pull-request.yml[R27-29]

+ # This repository builds one release target, the NuGet package (D1.1).+ # The filter 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.+ # Naming the inputs rather than excluding workflow files means a documentation-only or workflow-only pull request skips the smoke build rather than packing the library for nothing (D1.4, and scenarios S2 and S3).

Relevance

●●● Strong

Explicit comment rule directly prohibits governance identifiers; removing those references is a
deterministic local edit.

ⓘ Recommendations generated based on similar findings in past PRs

Evidence

Rule 2826588 explicitly prohibits comments that cite governance documents, standards, or policy IDs.
The cited added comment block contains multiple such identifiers.

3. Comment references external hub✗ Dismissed📘 Rule violation⚙ Maintainability

Description

The new merge-bot comment refers to the hub and to every fleet repo, describing cross-repository
architecture rather than only the local workflow. The checklist disallows comments that name or
discuss another repository, service, or project.

Code

.github/workflows/merge-bot-pull-request.yml[R3-4]

+# Thin caller: the merge-bot is the hub's reusable merge-bot-task.yml, which every fleet repo reaches rather than carries.+# The trigger is pull_request_target so the called workflow resolves from the trusted base rather than the PR head, and no job checks out PR code.

Relevance

●●● Strong

Explicit repository rule directly prohibits external-repository discussion; removing the comment is
a straightforward local fix.

ⓘ Recommendations generated based on similar findings in past PRs

Evidence

Rule 2826588 restricts comments to the surrounding file and prohibits references to other
repositories, services, or projects. The cited added comment explicitly discusses the hub's reusable
task and fleet repositories.

4. Workflow embeds extensive rationale✗ Dismissed📘 Rule violation⚙ Maintainability

Description

The changes job is preceded by a multi-line architectural rationale covering release targets,
publisher inputs, and several requirement scenarios. Workflow guidance requires this high-level
rationale to be consolidated into a single-line top summary rather than scattered above jobs.

Code

.github/workflows/test-pull-request.yml[R27-29]

+ # This repository builds one release target, the NuGet package (D1.1).+ # The filter 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.+ # Naming the inputs rather than excluding workflow files means a documentation-only or workflow-only pull request skips the smoke build rather than packing the library for nothing (D1.4, and scenarios S2 and S3).

Relevance

●●● Strong

Explicit workflow-comment rule directly requires concise summaries instead of scattered multi-line
architectural rationale.

ⓘ Recommendations generated based on similar findings in past PRs

Evidence

Rule 2826632 disallows large top-level rationale comments scattered across workflow jobs. The cited
three-line block explains release architecture and multiple scenarios rather than a short local
implementation detail.

Rule 2826632: Workflow YAML files must start with a single-line summary comment instead of extensive inline rationale

5. Package bump mixed with normalization✗ Dismissed📘 Rule violation⚙ Maintainability

Description

Directory.Packages.props is wholly rewritten for CRLF-to-LF normalization while also changing the
code-coverage package from 18.9.0 to 18.10.0. Mixing a substantive dependency edit into the
normalized file violates the required isolation of EOL-only changes.

Code

Directory.Packages.props[8]

+ <PackageVersion Include="Microsoft.Testing.Extensions.CodeCoverage" Version="18.10.0" />

Relevance

●●● Strong

The finding identifies a concrete token change inside an EOL-normalized file, directly violating the
stated isolation rule.

ⓘ Recommendations generated based on similar findings in past PRs

Evidence

Rule 2826678 requires an EOL-normalized file to contain no token changes. The diff removes and
re-adds all 16 lines while the cited declaration changes Microsoft.Testing.Extensions.CodeCoverage
from 18.9.0 to 18.10.0.

Rule 2826678: Isolate EOL normalization from content changes

## Issue Context
Keep CRLF-to-LF normalization isolated from substantive dependency updates so each changeset has only one kind of change.

🔵 Needs a closer look

It combines broad CI/publish workflow rewiring (hub-hosted calls, permissions/secrets scoping) with large-scale repo normalization and retirements that warrants final human validation.

Pull request overview

Promotes the develop branch state into main by aligning repository configuration, documentation, tooling, and CI wiring with the hub-resynced setup (including LF normalization and hub-hosted reusable workflows).

Changes:

• Normalize/standardize repo files (formatting and LF line endings) and refresh solution/workspace metadata.
• Move CI orchestration to hub-hosted reusable workflows and retire repo-local workflow task implementations/config payloads.
• Add/refresh carried skills and governance/architecture documentation to match the current fleet model.

[ptr727]

Answering the two Qodo review-body findings here, since they carry no thread to resolve. Both also have inline threads, which are answered and resolved there.

"Comments cite requirement identifiers" (test-pull-request.yml, citing D1.1, D1.4, S2, S3). Declined. Those identifiers are defined in WORKFLOW.md, which this repository carries and which this pull request changes, so they are pointers into this repository's own CI contract rather than an external policy reference. D1.1 and D1.4 are the guarantees the changes job implements, and S2 and S3 are the scenarios in that same file's test-methodology table asserting that a documentation-only and a workflow-only pull request skip the smoke build. The reference caller stub this file is adopted from carries the same citations verbatim, including (D1.1) on the filter and (D1.5, D7.4) on the aggregator.

"Comment references external hub" (merge-bot-pull-request.yml). Half declined, half taken. The rule invoked governs carried template files and states its own boundary, that a repository's own content is outside it, and a workflow is repository-owned. The reference is also in the runnable body rather than only the prose, since the job is uses: ptr727/ProjectTemplate/.github/workflows/merge-bot-task.yml@f3b4cc9. The wording point is fair though: "which every fleet repo reaches rather than carries" describes other repositories, and this repository's file has no reason to. That reword goes to develop rather than here, because this promotion's tree is byte-identical to develop's and editing it would leave main ahead on that file, which is the drift this promotion exists to remove.

The remaining two Qodo findings from the first round, on mixing the package bump and the README rewrite with the line-ending normalization, are answered in their own threads: the line-endings rule permits a broader maintenance change to normalize alongside content edits when it is called out and the content is verified separately with git diff --ignore-cr-at-eol, and both conditions are met.

Inline comments:
In @.config/dotnet-tools.json:
- Line 19: Close the root JSON object in the dotnet-tools manifest after the
tools object so the document is valid JSON and dotnet tool restore can parse it
successfully.
In @.github/skills/drive-pr/SKILL.md:
- Around line 46-48: Update the drive skill’s authorization guidance so
answering the how-far question only selects the target and cannot authorize a
feature-to-develop squash merge. Require separate explicit confirmation naming
that merge action before step 4 proceeds, or enforce an authenticated
maintainer-only invocation boundary, while preserving the prohibition on
develop-to-main promotion and release dispatch authorization.
In @.github/skills/git-commit-conventions/SKILL.md:
- Around line 89-90: Update the PowerShell instructions around the git init and
commit command to declare PowerShell 7 or later as a prerequisite, or replace
the && chain with explicit exit-code checks so the commands remain compatible
with Windows PowerShell 5.1.
In
@.github/skills/operational-vs-release-workflow/references/branch-protection-and-promotion.md:
- Around line 35-38: Update the merge-resolution workflow after resolving
EOL-conflicted files with git checkout --theirs <file>: stage every
resolved path using git add or git rm, then complete the merge with git commit
or git merge --continue before opening the promotion PR.
In @.github/skills/repo-worktree/SKILL.md:
- Around line 141-142: Update gh-write-guard.py so
GH_WRITE_GUARD_ALLOW_PRIMARY_CHECKOUT bypasses protection only for the approved
standalone-clone fallback path, validating the target path before allowing the
mutation. Keep primary-checkout writes denied even when the session variable is
non-falsy, and preserve the existing fallback checkout behavior.
In @.vscode/tasks.json:
- Line 142: Update the four lint task definitions in tasks.json to invoke
scripts/docker_lint.py instead of direct docker run commands, preserving each
task’s lint purpose and arguments. Ensure they use the governed wrapper’s digest
resolution, read-only workspace mounts, disabled networking, and timeout
controls rather than :latest images and writable mounts.
In `@AUDIT.md`:
- Line 28: Update the prose in AUDIT.md to replace “afterwards” with “afterward”
near the Fleet Bootstrap guidance, and replace “all-drifts” with a clear phrase
such as “PR that addresses all drift classes” at the later occurrence.
In `@GOVERNANCE.md`:
- Line 221: Update the boolean-input guidance in GOVERNANCE.md (lines 221-221)
and .github/skills/workflow-ci-contract/SKILL.md (lines 27-27): use direct
Boolean checks through inputs.foo, and only compare against string values when
reading github.event.inputs.foo. Keep the documented workflow_call and
workflow_dispatch declarations accurate in both documents.
In `@OPERATIONS.md`:
- Around line 27-30: Update the Docker image references in the documented
validation commands, including the repeated commands around the actionlint and
editorconfig-checker entries, to use approved immutable digests instead of
mutable tags such as latest. Preserve each command’s existing arguments and
update digests deliberately when changing image versions.
In `@Utilities/StringHistory.cs`:
- Around line 84-90: Update MaxFirstLines and MaxLastLines so limits cannot be
negative and changing them preserves retention immediately: either make the
properties initialization-only or, in their setters, re-partition _stringList
and synchronize _firstLines and _lastLines. Ensure subsequent appends never
retain more than the configured first and last limits.
- Line 82: Update the limit documentation near AppendLine and the corresponding
constructor parameter to describe one-sided zero behavior accurately: when one
limit is zero and the other is positive, retain entries only according to the
positive limit on that side, rather than stating that zero means no limit.

Promotes the hub resync (#451) to main.

Why this is a promote/ branch rather than develop itself

main carried its own copies of work develop had done independently: the Microsoft.Testing.Platform migration (#448 against #447) and an AwesomeAssertions bump (#450 against #449). Combined with the CRLF-to-LF renormalization, develop -> main conflicts on seven paths, and develop's required_linear_history plus its PR ruleset forbid resolving them on develop. This is the documented remedy: resolve on a throwaway branch off main, then open that into main.

The resolution is provably exactly develop

Every conflict was resolved to develop's side, and the result is byte-identical to develop's tree:

merged tree 503594305d3fe69900452453c806dedded8f1243
develop tree 503594305d3fe69900452453c806dedded8f1243

Each was confirmed lossless before develop was taken, per the documented check:

Path	Why taking develop drops nothing
global.json	Content-identical modulo EOL. main added it CRLF, develop renormalized it.
UtilitiesTests/UtilitiesTests.csproj	Content-identical modulo EOL.
UtilitiesTests/ExtensionsTests.cs	Content-identical modulo EOL.
Directory.Packages.props	Differs in one line, the coverage extension, where develop is the newer 18.10.0 against main's 18.9.0.
Utilities.slnx	main's extra entries are a duplicate dependabot.yml, a Data/ folder naming three files this repository does not contain, and the two workflow tasks develop deleted because the hub now hosts them. Verified each path is absent on develop, and that dependabot.yml is still listed there under GitHub Actions.
.github/workflows/build-release-task.yml	Deleted on develop per its retire disposition.
.github/workflows/validate-task.yml	Deleted on develop, which now calls the hub-hosted validator by pin.

Verification

Run against this branch's tree, not inferred from #451:

dotnet build 0 warnings, 0 errors
dotnet csharpier check . 43 files, clean
dotnet format style --verify-no-changes clean
dotnet test (MTP + coverage) 183/183 passed
markdownlint-cli2 '**/*.md' 48 files, 0 issues
actionlint clean
editorconfig-checker clean
repo_gate.py eol, eol-coverage, sha-pin all clean
prose_lint.py --diff origin/main clean

Merging

The head is promote/develop-to-main, not develop, so the delete-develop trap does not apply here. Merge with a merge commit rather than a squash, per the main ruleset.

📝 Walkthrough

Walkthrough

The pull request centralizes repository governance and agent procedures, adds fleet Skills and documentation, updates GitHub workflow composition, normalizes line endings and formatting, upgrades code coverage tooling, and adds the public StringHistory class with tests.

Changes

Repository governance and Skills

Layer / File(s)	Summary
Centralized governance and agent procedures AGENTS.md, GOVERNANCE.md, CODESTYLE.md, AUDIT.md, ARCHITECTURE.md, OPERATIONS.md, .github/copilot-instructions.md	Repository rules now use concise indexes and shared governance documents. Agent conduct, auditing, resynchronization, worktrees, review, release, and contribution procedures are defined in Skills.
Language, workflow, and documentation Skills .github/skills/*	New Skills define .NET, Python, Shell, workflow, Git, review, release, repository, and documentation procedures with supporting references.
Repository documentation and entry points README.md, CLAUDE.md, HISTORY.md, Utilities.slnx	Project documentation, release history, Claude entry-point guidance, and solution-item organization were updated.

Workflow and repository configuration

Layer / File(s)	Summary
Pinned validation and release workflows .github/workflows/test-pull-request.yml, .github/workflows/publish-release.yml, .github/workflows/merge-bot-pull-request.yml	Workflows now call pinned external reusable tasks, use scoped permissions and secrets, detect release-relevant changes, conditionally run smoke builds, and aggregate skipped jobs correctly.
Removed local reusable workflows .github/workflows/build-release-task.yml, .github/workflows/publish-plan-task.yml, .github/workflows/validate-task.yml	The local release, publish-plan, and validation workflow interfaces were deleted.
Formatting, line endings, and tooling configuration .editorconfig, .gitattributes, .editorconfig-checker.json, .markdownlint-cli2.jsonc, cspell.json, .gitignore, .husky/*, Directory.Packages.props, host-tools.json	LF is now the default with CRLF reserved for batch files. Checker exclusions, Markdown HTML rules, spelling scope, ignore patterns, host-tool declaration, and coverage package version were updated.

Library and tests

Layer / File(s)	Summary
StringHistory implementation and coverage Utilities/StringHistory.cs, UtilitiesTests/StringHistoryTests.cs	Added configurable first-line and last-line retention, bounded rolling behavior, validation, read-only storage, and newline rendering.
Existing source and test normalization Utilities/*.cs, UtilitiesTests/*.cs, Sandbox/*, project files, workspace files	Existing implementations, APIs, tests, assertions, and project settings were reformatted or normalized without stated behavioral changes.

Estimated code review effort: 3 (Moderate) | ~25 minutes

Merge Risk:🟠 High · up to 8af98

The promoted tree contains a malformed .NET tool manifest that blocks tool restoration, mutable history limits that can violate retention or throw on invalid input, and automation/workspace controls that can permit unintended merges or primary-checkout writes. These correctness and security risks make the PR not ready to merge until fixed.

High-Level Assessment

The following are alternative approaches to this PR:

1. Keep reusable workflows in-repo

• ➕ Workflow changes can be exercised directly from the repository head.
• ➕ The repository remains independent of hub availability.
• ➖ Duplicates generic orchestration across the fleet.
• ➖ Requires repeated synchronization and allows stale CI copies to report false conformance.

2. Resolve the promotion directly on develop

• ➕ Would avoid a temporary promotion branch.
• ➕ Keeps the promotion head on the normal integration branch.
• ➖ Develop's linear-history and pull-request rules prevent the required merge resolution.
• ➖ A back-merge would violate the forward-only branch model.

Recommendation: Use the current throwaway branch from main, resolve verified conflicts to develop's tree, and consume generic CI through commit-pinned hub workflows. This preserves branch protections, produces the proven develop-equivalent tree, and removes duplicated workflow maintenance while retaining repository-owned caller configuration.

🐞 Bugs (0)📘 Rule violations (0)📜 Skill insights (0)

1. README edits mixed with normalization✗ Dismissed📘 Rule violation⚙ Maintainability

Description

README.md combines a whole-file CRLF-to-LF rewrite with substantive additions including a table of
contents and new sections. This prevents the normalization from being reviewed as an isolated
EOL-only change.

Code

README.md[R39-42]

+## Table of Contents++- [Build and Distribution](#build-and-distribution)+ - [Build Status](#build-status)

Relevance

●●● Strong

The finding identifies substantive README additions in a file also rewritten for EOL normalization,
directly violating the isolation rule.

ⓘ Recommendations generated based on similar findings in past PRs

Evidence

Rule 2826678 allows EOL normalization only when visible content is unchanged. The patch replaces the
full 84-line base file with a 154-line file, and the cited newly added table of contents is a
substantive content change.

2. Comments cite requirement identifiers✗ Dismissed📘 Rule violation⚙ Maintainability

Description

The workflow comments cite D1.1, D1.4, S2, and S3 while explaining the job. These
governance-style identifiers are not change-local implementation context and violate the restriction
on policy or standard references in code-review comments.

Code

.github/workflows/test-pull-request.yml[R27-29]

+ # This repository builds one release target, the NuGet package (D1.1).+ # The filter 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.+ # Naming the inputs rather than excluding workflow files means a documentation-only or workflow-only pull request skips the smoke build rather than packing the library for nothing (D1.4, and scenarios S2 and S3).

Relevance

●●● Strong

Explicit comment rule directly prohibits governance identifiers; removing those references is a
deterministic local edit.

ⓘ Recommendations generated based on similar findings in past PRs

Evidence

Rule 2826588 explicitly prohibits comments that cite governance documents, standards, or policy IDs.
The cited added comment block contains multiple such identifiers.

3. Comment references external hub✗ Dismissed📘 Rule violation⚙ Maintainability

Description

The new merge-bot comment refers to the hub and to every fleet repo, describing cross-repository
architecture rather than only the local workflow. The checklist disallows comments that name or
discuss another repository, service, or project.

Code

.github/workflows/merge-bot-pull-request.yml[R3-4]

+# Thin caller: the merge-bot is the hub's reusable merge-bot-task.yml, which every fleet repo reaches rather than carries.+# The trigger is pull_request_target so the called workflow resolves from the trusted base rather than the PR head, and no job checks out PR code.

Relevance

●●● Strong

Explicit repository rule directly prohibits external-repository discussion; removing the comment is
a straightforward local fix.

ⓘ Recommendations generated based on similar findings in past PRs

Evidence

Rule 2826588 restricts comments to the surrounding file and prohibits references to other
repositories, services, or projects. The cited added comment explicitly discusses the hub's reusable
task and fleet repositories.

4. Workflow embeds extensive rationale✗ Dismissed📘 Rule violation⚙ Maintainability

Description

The changes job is preceded by a multi-line architectural rationale covering release targets,
publisher inputs, and several requirement scenarios. Workflow guidance requires this high-level
rationale to be consolidated into a single-line top summary rather than scattered above jobs.

Code

.github/workflows/test-pull-request.yml[R27-29]

+ # This repository builds one release target, the NuGet package (D1.1).+ # The filter 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.+ # Naming the inputs rather than excluding workflow files means a documentation-only or workflow-only pull request skips the smoke build rather than packing the library for nothing (D1.4, and scenarios S2 and S3).

Relevance

●●● Strong

Explicit workflow-comment rule directly requires concise summaries instead of scattered multi-line
architectural rationale.

ⓘ Recommendations generated based on similar findings in past PRs

Evidence

Rule 2826632 disallows large top-level rationale comments scattered across workflow jobs. The cited
three-line block explains release architecture and multiple scenarios rather than a short local
implementation detail.

5. Package bump mixed with normalization✗ Dismissed📘 Rule violation⚙ Maintainability

Description

Directory.Packages.props is wholly rewritten for CRLF-to-LF normalization while also changing the
code-coverage package from 18.9.0 to 18.10.0. Mixing a substantive dependency edit into the
normalized file violates the required isolation of EOL-only changes.

Code

Directory.Packages.props[8]

+ <PackageVersion Include="Microsoft.Testing.Extensions.CodeCoverage" Version="18.10.0" />

Relevance

●●● Strong

The finding identifies a concrete token change inside an EOL-normalized file, directly violating the
stated isolation rule.

ⓘ Recommendations generated based on similar findings in past PRs

Evidence

Rule 2826678 requires an EOL-normalized file to contain no token changes. The diff removes and
re-adds all 16 lines while the cited declaration changes Microsoft.Testing.Extensions.CodeCoverage
from 18.9.0 to 18.10.0.

🔵 Needs a closer look

It combines broad CI/publish workflow rewiring (hub-hosted calls, permissions/secrets scoping) with large-scale repo normalization and retirements that warrants final human validation.

Pull request overview

Promotes the develop branch state into main by aligning repository configuration, documentation, tooling, and CI wiring with the hub-resynced setup (including LF normalization and hub-hosted reusable workflows).

Changes:

• Normalize/standardize repo files (formatting and LF line endings) and refresh solution/workspace metadata.
• Move CI orchestration to hub-hosted reusable workflows and retire repo-local workflow task implementations/config payloads.
• Add/refresh carried skills and governance/architecture documentation to match the current fleet model.

[ptr727]

Answering the two Qodo review-body findings here, since they carry no thread to resolve. Both also have inline threads, which are answered and resolved there.

"Comments cite requirement identifiers" (test-pull-request.yml, citing D1.1, D1.4, S2, S3). Declined. Those identifiers are defined in WORKFLOW.md, which this repository carries and which this pull request changes, so they are pointers into this repository's own CI contract rather than an external policy reference. D1.1 and D1.4 are the guarantees the changes job implements, and S2 and S3 are the scenarios in that same file's test-methodology table asserting that a documentation-only and a workflow-only pull request skip the smoke build. The reference caller stub this file is adopted from carries the same citations verbatim, including (D1.1) on the filter and (D1.5, D7.4) on the aggregator.

"Comment references external hub" (merge-bot-pull-request.yml). Half declined, half taken. The rule invoked governs carried template files and states its own boundary, that a repository's own content is outside it, and a workflow is repository-owned. The reference is also in the runnable body rather than only the prose, since the job is uses: ptr727/ProjectTemplate/.github/workflows/merge-bot-task.yml@f3b4cc9. The wording point is fair though: "which every fleet repo reaches rather than carries" describes other repositories, and this repository's file has no reason to. That reword goes to develop rather than here, because this promotion's tree is byte-identical to develop's and editing it would leave main ahead on that file, which is the drift this promotion exists to remove.

The remaining two Qodo findings from the first round, on mixing the package bump and the README rewrite with the line-ending normalization, are answered in their own threads: the line-endings rule permits a broader maintenance change to normalize alongside content edits when it is called out and the content is verified separately with git diff --ignore-cr-at-eol, and both conditions are met.

Inline comments:
In @.config/dotnet-tools.json:
- Line 19: Close the root JSON object in the dotnet-tools manifest after the
tools object so the document is valid JSON and dotnet tool restore can parse it
successfully.
In @.github/skills/drive-pr/SKILL.md:
- Around line 46-48: Update the drive skill’s authorization guidance so
answering the how-far question only selects the target and cannot authorize a
feature-to-develop squash merge. Require separate explicit confirmation naming
that merge action before step 4 proceeds, or enforce an authenticated
maintainer-only invocation boundary, while preserving the prohibition on
develop-to-main promotion and release dispatch authorization.
In @.github/skills/git-commit-conventions/SKILL.md:
- Around line 89-90: Update the PowerShell instructions around the git init and
commit command to declare PowerShell 7 or later as a prerequisite, or replace
the && chain with explicit exit-code checks so the commands remain compatible
with Windows PowerShell 5.1.
In
@.github/skills/operational-vs-release-workflow/references/branch-protection-and-promotion.md:
- Around line 35-38: Update the merge-resolution workflow after resolving
EOL-conflicted files with git checkout --theirs <file>: stage every
resolved path using git add or git rm, then complete the merge with git commit
or git merge --continue before opening the promotion PR.
In @.github/skills/repo-worktree/SKILL.md:
- Around line 141-142: Update gh-write-guard.py so
GH_WRITE_GUARD_ALLOW_PRIMARY_CHECKOUT bypasses protection only for the approved
standalone-clone fallback path, validating the target path before allowing the
mutation. Keep primary-checkout writes denied even when the session variable is
non-falsy, and preserve the existing fallback checkout behavior.
In @.vscode/tasks.json:
- Line 142: Update the four lint task definitions in tasks.json to invoke
scripts/docker_lint.py instead of direct docker run commands, preserving each
task’s lint purpose and arguments. Ensure they use the governed wrapper’s digest
resolution, read-only workspace mounts, disabled networking, and timeout
controls rather than :latest images and writable mounts.
In `@AUDIT.md`:
- Line 28: Update the prose in AUDIT.md to replace “afterwards” with “afterward”
near the Fleet Bootstrap guidance, and replace “all-drifts” with a clear phrase
such as “PR that addresses all drift classes” at the later occurrence.
In `@GOVERNANCE.md`:
- Line 221: Update the boolean-input guidance in GOVERNANCE.md (lines 221-221)
and .github/skills/workflow-ci-contract/SKILL.md (lines 27-27): use direct
Boolean checks through inputs.foo, and only compare against string values when
reading github.event.inputs.foo. Keep the documented workflow_call and
workflow_dispatch declarations accurate in both documents.
In `@OPERATIONS.md`:
- Around line 27-30: Update the Docker image references in the documented
validation commands, including the repeated commands around the actionlint and
editorconfig-checker entries, to use approved immutable digests instead of
mutable tags such as latest. Preserve each command’s existing arguments and
update digests deliberately when changing image versions.
In `@Utilities/StringHistory.cs`:
- Around line 84-90: Update MaxFirstLines and MaxLastLines so limits cannot be
negative and changing them preserves retention immediately: either make the
properties initialization-only or, in their setters, re-partition _stringList
and synchronize _firstLines and _lastLines. Ensure subsequent appends never
retain more than the configured first and last limits.
- Line 82: Update the limit documentation near AppendLine and the corresponding
constructor parameter to describe one-sided zero behavior accurately: when one
limit is zero and the other is positive, retain entries only according to the
positive limit on that side, rather than stating that zero means no limit.
