Normalize line endings to LF and pin the generator's output to LF - #547
Conversation
Carry the hub's line-ending governance: `.gitattributes` becomes `* text=auto eol=lf` with the `*.bat`/`*.cmd` CRLF exception, and `.editorconfig` declares `end_of_line = lf` on `[*]` with the same single CRLF exception, replacing the per-type CRLF pins the old model needed. The repo-specific LF pins for `*.sh`, `.husky/pre-commit`, `Docker/s6-overlay/**` and the Dockerfiles are dropped because the global LF default now covers them. Renormalize the 85 tracked CRLF files to LF in the same pass. The generator has to move with the tree, or the codegen App would rewrite its own outputs back to CRLF on its next scheduled run and fight `.gitattributes` indefinitely. The four `JsonSourceGenerationOptions` newline pins become `\n`, and `AppendLineCrlf` becomes `AppendLineLf`. `ComposeFile.Create` now normalizes at the write, the way `Dockerfile.Create` already did, so the output ending no longer depends on how the C# source itself is stored. Verified: `Make/Matrix.json`, `Make/Version.json` and the three `Make/Test*.yml` compose files regenerate byte-identical to the LF-normalized tree, 21/21 tests pass, and CSharpier, `dotnet format style --verify-no-changes`, editorconfig-checker, markdownlint and cspell are all clean.

🟢 Approval recommended
The line-ending policy change is consistently applied and the generator changes ensure future codegen outputs remain LF-stable.
Pull request overview
This PR updates repository line-ending governance to normalize all text files to LF and aligns the CreateMatrix generator to emit LF so generated outputs remain stable under the new .gitattributes/.editorconfig rules.
Changes:
- Normalize repo-wide line endings to LF via
.gitattributes+.editorconfig, keeping*.bat/*.cmdas the sole CRLF exception. - Update
CreateMatrixJSON source-generation and compose-file writing paths to use\n(and normalize at write) to prevent future CRLF drift. - Renormalize tracked text files so the working tree and index are consistent with the new policy.

…nd modifier `ComposeFile.Create` appended a section separator after the last service, so every generated compose file ended with two blank lines and yamllint reported `too many blank lines`. It now trims to a single trailing newline, matching what `Dockerfile.Create` already did. Pre-existing, but this is the commit that rewrites that writer. `HISTORY.md` line 10 used `version-forward-release only` as a compound modifier. Both raised by CodeRabbit on #547. Verified: the three compose files regenerate with a single trailing newline, still parse as YAML, and 21/21 tests pass.

🟢 Approval recommended
The substantive generator changes consistently enforce LF output and repository-wide LF governance is coherent with the declared CRLF exceptions.

#547 squash-merged into develop, so develop's tree is now byte-identical to this branch's ancestor 2efaeb2 while carrying a different commit id. The textual conflicts that produces are all cases where both sides made the same change, so this merge is recorded with the branch's tree, which already contains every one of those changes plus the runner migration on top. Verified before recording: `git diff origin/develop 2efaeb2` is empty, so the squash reproduced the branch's ancestor exactly and develop carries nothing this branch lacks.
…packages (#553) Unblocks the Dependabot nuget PRs (#545, #546) and every later nuget bump. **Replaces #549**, which GitHub closed automatically when its base branch `resync/eol-lf` was deleted on #547's merge. Same branch, same content, same review history on the closed PR. This one targets `develop` directly. The branch carries a `-s ours` merge of `develop` recorded after #547 squashed. That is lossless here and was verified before recording: `git diff origin/develop 2efaeb2` is empty, so the squash reproduced this branch's own ancestor exactly, and that ancestor is reachable from this branch, so `develop` carries nothing the branch lacks. The diff against `develop` is the five files below and nothing else. > Reworked after ptr727/ProjectTemplate#1111 merged. The first revision used > `coverlet.MTP`, which was the open recommendation at the time. The hub has since > settled WORKFLOW.md D1.6 on `Microsoft.Testing.Extensions.CodeCoverage`, and this > PR now follows that instead. ## The problem `xunit.v3` 4.0.0 removed the VSTest bridge, so the CI unit-test step's `dotnet test --collect:"XPlat Code Coverage"` now fails outright on the .NET 10 SDK: ```text error : Testing with VSTest target is no longer supported by Microsoft.Testing.Platform on .NET 10 SDK and later. If you use dotnet test, you should opt-in to the new dotnet test experience. ``` That is what #545 and #546 have been red on, and it blocks every later bump until the runner moves. ## The fix, per WORKFLOW.md D1.6 | Change | Why | | --- | --- | | `global.json` with `{"test":{"runner":"Microsoft.Testing.Platform"}}` | opts into the native MTP runner. No `sdk` section, so SDK resolution and roll-forward are untouched. | | drop `xunit.runner.visualstudio` | the VSTest adapter MTP replaces | | `coverlet.collector` -> `Microsoft.Testing.Extensions.CodeCoverage` 18.9.0 | coverlet's VSTest data collector is ignored under MTP without failing | | CI step -> `dotnet test --coverage --coverage-output-format cobertura --results-directory ./coverage`, then prefix each report to `coverage-<guid>.cobertura.xml` | matches the hub's `validate-task.yml` byte for byte | Three details are load-bearing, and none of them reds the job on its own: - **The 18.9.0 floor.** Below 18.1.0 the extension is built against Microsoft.Testing.Platform 1.x and throws `TypeLoadException` against the 2.x platform xunit.v3 4.0.0 carries. It then runs **zero tests** and still writes a well-formed Cobertura file reporting full coverage. - **`--coverage-output` stays unset.** Pinning one filename would give every test project in a solution the same path, and the last to finish would overwrite the rest. - **The prefix rename.** The default `<guid>.cobertura.xml` that the unset flag produces is a name codecov-cli's finder does not match (its patterns are `*coverage*.*` and an exact `cobertura.xml`), so an unprefixed report uploads nothing while the step still exits green. Package bumps the runner change unblocks: AwesomeAssertions 9.5.0 -> 9.6.0, xunit.analyzers 1.27.0 -> 2.0.0, xunit.v3 3.2.2 -> 4.0.0. `Microsoft.NET.Test.Sdk` stays at 18.9.0 (already current). `.gitignore` gains the hub's dotnet coverage block verbatim. The output was untracked and unignored, so a blanket `git add -A` after a local coverage run would have staged it. ## Verification Against the real invocation, not the documented one: - 21 tests **ran** and passed, which is the check that matters given the zero-test failure mode above. - Resolved graph (from `obj/project.assets.json`, not the csproj text): `Microsoft.Testing.Extensions.CodeCoverage/18.9.0`, `Microsoft.Testing.Platform/2.3.3`, `xunit.v3/4.0.0` with the `mtp-v2` variants. No coverlet, no `xunit.runner.visualstudio`. - The run wrote `bbfde807-....cobertura.xml` and the prefix step renamed it to `coverage-bbfde807-....cobertura.xml`, confirming the rename is genuinely needed rather than defensive. - `git check-ignore` covers both filename shapes; `git ls-files -z | xargs -0 git check-ignore -v` is empty. - `validate-task.yml` is the only `dotnet test` caller; `publish-release.yml` and `test-pull-request.yml` both reach it via `uses:`, so the publish gate and the PR gate move together. No `--collect` survives anywhere. - Build, CSharpier, `dotnet format style --verify-no-changes`, editorconfig-checker, actionlint, markdownlint and cspell all clean. **One thing worth knowing:** the reported coverage number moves, because the engine does. Line rate goes from 0.59 under coverlet to 0.26 here, with lines-valid 1350 -> 3143, since this engine instruments more of the graph. It cannot gate anything: `codecov.yml` sets `informational: true` on both project and patch, and the only ruleset-required check is `Check pull request workflow status job`. ## Notes - Dependabot dual-targets `develop` and `main`, so #546 (the `main` copy) stays blocked until this reaches `main` via the promotion PR. `main`'s tree is not broken in the meantime, it just cannot take the bump. - The fleet audit flags this repo's local `validate-task.yml` as `hub-only`. Now that ptr727/ProjectTemplate#1111 has landed MTP support in the hub's reusable workflow, that migration is unblocked, but it is a separate interface change covering five workflow files and belongs in its own PR rather than here. <!-- This is an auto-generated comment: release notes by coderabbit.ai --> ## Summary by CodeRabbit * **Improvements** * Improved automated test execution and code coverage reporting in continuous integration. * Coverage reports are now generated in a standardized format for more reliable analysis. * **Documentation** * Added guidance for running tests locally and understanding coverage validation. * **Chores** * Updated testing tools and configuration to use the modern test platform. * Added rules to keep generated test and coverage files out of source control. <!-- end of auto-generated comment: release notes by coderabbit.ai -->
…nfig (#550) The mechanical half of the ProjectTemplate resync. Audit run `2026-08-30T03:26:30Z | hub a378121`, re-measured against hub `f3b4cc9`. Stacked on #549 (which is stacked on #547), so this PR is based on `resync/dotnet-mtp` and will retarget as its parents merge. Its own diff is the five items below. ## What changed **`.github/skills/` (37 files), carried whole.** A manifest-owned tree, applied with the hub's own `scripts/carry.py apply` rather than by hand. `carry.py check` now reports `sourceDigest == targetDigest == c5475deb46bfbf1f9253bc6128a40b7686687597ebe38a6cd1c580a39817f03e` with `extra`, `missing` and `modified` all empty, so this is the hub's content byte for byte. **`host-tools.json`**, the repo's own tighten-only overlay on the fleet host-tool declaration. The `tools` list is empty because this repo needs nothing the fleet declaration does not already carry, and the file is present anyway so the declaration is somewhere a reader can find rather than somewhere they have to know to look. The hub's `$schema` pointer is deliberately not carried: it is a relative path to a hub-only schema, and the hub's own note instructs a copying repo to leave it behind. **`.markdownlint-cli2.jsonc`** re-vendored whole, it being `verbatim` fidelity. The only real change is two comment lines, `markdown` -> `Markdown`. **`.editorconfig-checker.json`** takes the hub's `Exclude` list. The entries are Python cache directories, inert here, carried whole per the fleet's config-carry model. `Exclude` is additive to the tool's built-in defaults, so it can only narrow the scan, never widen it. The `Disable` block is untouched. **`cspell.json` becomes the single source of truth.** It is now the union of three lists: the hub's 134 words, this repo's existing 164, and the 97-word `cSpell.words` block that lived in `NxWitness.code-workspace`, 29 of which existed nowhere else. That workspace block is deleted, per CODESTYLE.md "Markdown and Spelling". ## Verification - Set-checked the word union against all three sources: **zero words dropped**, zero extras not traceable to a source, zero exact duplicates. Every non-`words` key (`version`, `language`, `ignorePaths`, `ignoreRegExpList`) preserved with its value and position. The original carried no JSONC comment to lose. - `NxWitness.code-workspace` still parses as JSONC. Diffing the parsed objects before and after, `settings` differs by exactly one removed key and nothing else; `folders` and `extensions` are identical. The `streetsidesoftware.code-spell-checker` recommendation is retained, so the editor still reads `cspell.json` from the workspace root. - `.markdownlint-cli2.jsonc` byte-matches the hub, as `verbatim` requires. - `host_gate.py --repo <this checkout>` returns `0 issue(s) over 8 declared tool(s)`, and the file validates against the hub's `spec/host-tools-local.schema.json`, which marks `$schema` optional. - markdownlint clean across all 45 markdown files (up from 8), cspell clean at the CI scope, editorconfig-checker clean, every touched JSON/JSONC file parses, and no tracked file carries a CR. ## Deliberately not in this PR Three audit findings are real but do not belong to the mechanical class, and one is not a defect at all: - **The `AGENTS.md` split** into `CLAUDE.md`, `GOVERNANCE.md`, `ARCHITECTURE.md` and `OPERATIONS.md`. A distinctive-phrase probe against the hub canonical found that this repo's `AGENTS.md` predates the router split and mixes stale fleet law with substantial local content, including the entire "Template adaptations" record of deliberate deviations. Re-vendoring over it would delete that silently, which is the exact incident the fleet's `carried-instruction-file-guard` exists to prevent. That needs its own PR and its own review. - **The `repo-config/` retirement.** `spec/divergences.json` marks the whole tree `retire`, but the deletion owes a tree-wide reference sweep, and the live inbound references are in `AGENTS.md` and `WORKFLOW.md`, both of which the split PR rewrites. Doing the deletion here would edit those files twice. - **README structure** (10 letter-class findings). Content work, grouped with the doc PR. - **The two `interface` findings are not drift to fix.** `publish-release.yml` "missing required job `publish`" and `merge-bot-pull-request.yml` "missing required job `merge-bot`" both resolve to *calling a hub-hosted task workflow* (`build-release-task.yml`, `merge-bot-task.yml`) that this repo has not adopted. `spec/divergences.json` states adoption "is a separate, later change per repo". This repo's multi-image, shared-base fan-out is a documented deviation, so renaming jobs to satisfy the checker would misreport the state rather than fix it. <!-- This is an auto-generated comment: release notes by coderabbit.ai --> ## Summary by CodeRabbit * **Documentation** * Added guidance for repository setup, coding standards, testing, reviews, releases, worktrees, contributions, host tools, and instruction preservation. * Added references for Markdown links, line endings, project configuration, testing, release publishing, and workflow guarantees. * **Maintenance** * Expanded spelling and Markdown terminology coverage. * Excluded Python caches and virtual environments from configuration checks. * Added a repository-level host-tools configuration placeholder. * Removed the workspace-specific spelling dictionary. * **Security** * Restricted validation workflows to read-only repository permissions. <!-- end of auto-generated comment: release notes by coderabbit.ai -->
…551) The judgment half of the ProjectTemplate resync: the `AGENTS.md` split, and the `repo-config/` retirement that depends on it. Stacked on #550 (which is stacked on #549 and #547), so this PR is based on `resync/hub-conformance` and will retarget as its parents merge. ## Why this is not a re-vendor This repo's `AGENTS.md` predated the hub's `AGENTS.md`/`GOVERNANCE.md` router split, so it held two different things in one 243-line file: stale copies of fleet law, and local rules written for faults the fleet has not seen elsewhere. Copying the hub canonical over it would have deleted the second kind silently, with no error and nothing in the diff that looks wrong. That is the exact incident the fleet's `carried-instruction-file-guard` exists to prevent. So every unit was probed by distinctive phrase against the hub canonical first, and each one that turned out to be local got a destination rather than a deletion. A 29-phrase preservation checklist taken from the pre-split file confirms every unit has a home. ## What moved where | | | | --- | --- | | `AGENTS.md` | 243 lines -> 115. Only the three declared sections, all three byte-identical to the hub. | | `CLAUDE.md` | New, byte-matches the hub. Claude Code reads `CLAUDE.md` and never `AGENTS.md`, so without it that provider had no rules at all. | | `GOVERNANCE.md` | New, 21 sections. The 18 verbatim ones byte-match the hub; `Devcontainer` and `Repository Layout` are intent-fidelity and written for this repo. | | `ARCHITECTURE.md` | New. Product and variant matrix, codegen data flow, base/derived image relationship, CI pipeline with its do-not-reintroduce list, and the Template Adaptations record. | | `OPERATIONS.md` | New. The six mandated headings, `Local Verification` first. | | `CODESTYLE.md` | Gains the encoding rule and the human-authored-comment rule, both stated in the old `AGENTS.md`. | **`Where the Rules Live` is carried unedited.** The first draft added two table rows pointing at the new docs. That section is declared `verbatim`, and `spec/fidelity-model.md` normalizes only line endings, action pins and job `needs:`, so those rows would have made it modified fixed content with no disposition on file, rendering UNTRIAGED in the divergence report. The two docs are routed from the preamble instead, which is not a declared section. **The Template Adaptations record is the piece that most needed preserving.** All ten bullets survive. Without them, every one of this repo's deliberate deviations from the fleet template reads as unexplained drift to the next audit. **Two rules were nearly lost and are restored.** "Leave human-authored comments exactly as written" is now a `CODESTYLE.md` item, and it matters because the carried comment rules push the other way: they tell an agent to collapse a short two-line comment, with nothing telling it to leave a maintainer's alone. The encoding rule survived only as `.editorconfig`'s `charset` and is now stated. **One claim the old file carried is false and is corrected, not copied.** "Linting is editor-only (no CI lint job)" is contradicted by `validate-task.yml`, which runs markdownlint, cspell, actionlint and editorconfig-checker inside the required check. `OPERATIONS.md` says what actually runs. ## The `repo-config/` retirement `spec/divergences.json` marks the payloads, the script and the reference as hub-hosted, so this repo reaches them rather than carrying a copy that drifts. The deletion swept every inbound reference: - six sites in `WORKFLOW.md`, which now name the behavior and the hub-hosted command instead of a local path, - a comment in `test-pull-request.yml`, - and the `Repo Config` solution folder in `NxWitness.slnx`, which would otherwise have shown five missing files in Visual Studio while `dotnet sln list` stayed silent about it. ## Pointers that moved with the sections Splitting a file moves the anchors other files point into, so those move too: four anchors in `.github/copilot-instructions.md` and three in `CODESTYLE.md` now resolve to `GOVERNANCE.md`, `WORKFLOW.md`'s D3.3 aside names the section that holds the rule, and `publish-release.yml`'s comment names `ARCHITECTURE.md`. `.github/copilot-instructions.md` also gains its declared `Reviewing Carried Fleet Content` section, and its closing paragraph states the behavior rather than naming the template repo and an anchor that no longer exists, which closes the audit's `carried:` finding against that file. ## Verification - The 29-phrase preservation checklist: every unit has a home. - All three `AGENTS.md` sections, all 18 verbatim `GOVERNANCE.md` sections, and `CLAUDE.md` byte-match the hub. Only the two declared-`intent` sections differ. - `OPERATIONS.md` carries exactly the six mandated headings in the mandated order, each with content. - `NxWitness.slnx` still parses as XML and the solution still builds clean. - Every relative Markdown link in a changed file resolves. - No `repo-config/` reference survives outside carried hub content that legitimately means the hub's own copy. - markdownlint (48 files), cspell, editorconfig-checker and actionlint all clean. ## Known, not fixed here `README.md` has a pre-existing broken relative link (`./LSIO/etc/s6-overlay/s6-rc.d/init-nx-relocate/run`). It is untouched by this commit and belongs with the README-structure work, which is the last audit class still open. <!-- This is an auto-generated comment: release notes by coderabbit.ai --> ## Summary by CodeRabbit - **Documentation** - Added architecture and operations guides covering products, build workflows, verification, CI/CD, troubleshooting, and recovery. - Added governance guidance for repository standards, releases, security, reviews, tooling, and supported platforms. - Added a Claude Code entry point and updated contributor guidance, workflow documentation, and coding standards. - Expanded the spelling dictionary with project-specific terminology. - **Chores** - Moved repository-configuration references from local files to centrally maintained configuration. - Removed obsolete repository configuration files and solution-folder entries. - Updated workflow comments and documentation links to reflect the new structure. <!-- end of auto-generated comment: release notes by coderabbit.ai -->
Promotes the ProjectTemplate resync to `main`. Five pull requests, merged to `develop` in order: #547, #553, #550, #551, #552. **Replaces #555.** That one opened `develop` directly into `main` and went `DIRTY`, which is the spurious EOL-only promotion conflict the fleet's own branching guidance names: `develop` flipped the `.editorconfig` line-ending default to LF and `main` has not caught up, so every renormalized path conflicts whole-file. `develop`'s squash-only ruleset and required linear history forbid resolving on `develop` itself, so the resolution is prepared on this throwaway branch off `main`, exactly as that guidance prescribes. Five files conflicted. Each was checked with the documented test rather than resolved on the shape of the conflict. `CreateMatrix/CreateMatrix.csproj`, `Make/Matrix.json` and `Make/Version.json` are content-identical modulo EOL. `CODESTYLE.md` and `CreateMatrixTests/CreateMatrixTests.csproj` genuinely differ, so each was proved a superset instead: every line present only on `main` is a superseded version, being the `AGENTS.md` routing that `develop` repointed to `GOVERNANCE.md`, the CRLF line-endings item, two list items renumbered when the encoding rule was inserted, and the pre-MTP test packages. **The merged tree is byte-identical to `develop`**, so nothing on `main` survives that `develop` had not already replaced. ## What lands | | | | --- | --- | | **Line endings** | `.gitattributes` becomes `* text=auto eol=lf` and `.editorconfig` declares `end_of_line = lf` on `[*]`, with `*.bat`/`*.cmd` the one CRLF exception. 85 tracked files renormalized. The `CreateMatrix` generator moves with them, or the codegen App would rewrite its own outputs back to CRLF on its next scheduled run. | | **Test runner** | Native Microsoft.Testing.Platform per WORKFLOW.md D1.6, as the hub settled it in ptr727/ProjectTemplate#1111. Unblocks the Dependabot bumps that had been red since xunit.v3 4.0.0 dropped the VSTest bridge. | | **Carried content** | The hub's `.github/skills/` tree (37 files, digest-verified), `host-tools.json`, `CLAUDE.md`, `GOVERNANCE.md`, and the shared lint config. | | **Instruction set** | `AGENTS.md` split onto the router model, from 243 lines to 115, with the repo-specific half moved to new `ARCHITECTURE.md` and `OPERATIONS.md`. `repo-config/` retired. | | **README** | Restructured to the fleet shape, eleven `readme-structure` findings closed, and the 2.15 release documented. | | **Security** | `validate-task.yml` and `test-pull-request.yml` given least privilege. They ran with the repository default, which is `write` on this repo with `can_approve_pull_request_reviews` true, while only ever reading the tree. | ## Reviewing the diff `git diff --ignore-cr-at-eol origin/main origin/develop` reduces the 143-file diff to the substantive changes. Everything else is the CRLF-to-LF renormalization, which is the EOL-only promotion conflict the fleet's own branching guidance names. ## Checks before opening this `main` carries no content `develop` lacks. `git diff --ignore-cr-at-eol origin/develop origin/main` shows 980 lines present only on `main`, and every one is a superseded version of something `develop` deliberately changed: `main`'s CRLF `.editorconfig` pins, its `* -text` `.gitattributes`, its pre-split 243-line `AGENTS.md`, its `AppendLineCrlf` generator, its `set -euo` run blocks. No file has content on `main` that is not either carried forward or intentionally replaced. The three commits labelled main-only were checked individually rather than assumed, since those are the ones the develop-staleness rule exists for: the cspell CI scope from #515/#517 is byte-identical on both branches, `CODESTYLE.md`'s "Spelling CI scope" from #516 is present, and the author-identity rule from #511 is in the carried `GOVERNANCE.md`. The commit counts look alarming and are not: `develop` is 19 ahead and 99 behind, but 70 of those 99 are bot merges that dual-target both branches as separate commits, and most of the rest are `main`'s own promotion merge commits, which never flow back by construction. ## Not in this promotion - **Two `interface` audit findings stay open by decision.** `publish-release.yml` missing job `publish` and `merge-bot-pull-request.yml` missing job `merge-bot` both resolve to adopting hub-hosted task workflows this repo has not adopted, and `spec/divergences.json` states adoption "is a separate, later change per repo". Renaming jobs to satisfy the checker would report conformance without adopting anything. - **The publish chain's workflow permissions**, filed as #554. Least privilege there is not `contents: read`, a wrong scope breaks publishing rather than failing a lint, and it would surface on a weekly scheduled run. - **An inert xUnit sequential collection**, filed as #548. ## Filed upstream Four issues against `ptr727/ProjectTemplate` from work this resync exposed: promotion candidates and two misleading interface findings (#1116, including my own correction retracting six of ten), the MTP zero-tests-locally behaviour (#1122), the version-floor guardrail (#1124), and 18 findings against carried canonical content that cannot be fixed downstream (#1131). ## Owed after merge The GitHub About description still carries the retired tagline. It feeds the Docker Hub short description through the docker-readme task, so that surface disagrees with the README until it is set by hand. `registry/repos.json` declares no `description` for this repo, so the configure script cannot write it. <!-- This is an auto-generated comment: release notes by coderabbit.ai --> ## Summary by CodeRabbit - **Documentation** - Reorganized project documentation around NxWitness, including build, distribution, releases, product variants, troubleshooting, and release notes. - Added architecture, governance, operations, and comprehensive development guidance. - **Developer Experience** - Added editor tasks for building, formatting, validation, testing, and linting. - Standardized line endings and formatting across project files. - **CI and Quality** - Improved shell error reporting and workflow permission safety. - Updated coverage generation and test tooling. - Added stricter Markdown and spelling validation. <!-- end of auto-generated comment: release notes by coderabbit.ai -->
Part 1 of the ProjectTemplate resync, the line-ending drift class on its own so the
whitespace churn stays reviewable. Audit run
2026-08-30T03:26:30Z | hub a378121.What changed
Line-ending governance carried from the hub.
.gitattributesbecomes* text=auto eol=lfwith the*.bat/*.cmdCRLF exception, matching the hub canonicalbyte for byte.
.editorconfigdeclaresend_of_line = lfon[*]and keeps only thatsame CRLF exception. The per-type CRLF pins (
[*.md],[*.{xml,csproj,props,targets}],[*.{yml,yaml}],[*.{json,jsonc}],[*.cs]) and the now-redundant LF pins(
[.github/workflows/*],[*.sh],.husky/pre-commit,Docker/s6-overlay/**,Dockerfile,*.Dockerfile) are removed, because the global LF default covers every oneof them. The repo has no
.bat,.cmdor.ps1file, so the CRLF exception is carriedinert, per the fleet's carry-both-files-whole model.
85 tracked CRLF files renormalized to LF. Every tracked text file now reports
i/lf w/lfundergit ls-files --eol; the two PNGs stay-textand byte-preserved.The generator moves with the tree. This is the part that is not cosmetic.
CreateMatrixemitted CRLF explicitly, so the codegen App would have rewritten its own committed outputs
back to CRLF on its next scheduled run and fought
.gitattributesindefinitely. FourJsonSourceGenerationOptionsNewLinepins become"\n",AppendLineCrlfbecomesAppendLineLf, andComposeFile.Createnormalizes at the write the wayDockerfile.Createalready did. That last one matters beyond this PR: C# raw string literals carry whatever
ending the
.cssource is stored with, so normalizing at the write makes the outputindependent of how a contributor's editor saves the source.
The carried docs that stated the old rule.
AGENTS.md"Line Endings",CODESTYLE.mditem 5, and
WORKFLOW.md's workflow-YAML bullet each described the CRLF-default model andwould have told the next agent to write CRLF into a tree that now normalizes to LF.
WORKFLOW.md's bullet was already wrong before this change (it claimed workflow YAML wasCRLF while
.editorconfigpinned it LF); this is the commit that touches the governance itmisstated, so it is corrected here.
Verification
Make/Matrix.json,Make/Version.jsonand the threeMake/Test*.ymlcompose filesregenerate byte-identical to the LF-normalized tree (
matrixandmakecommands runagainst the committed
Version.json, no drift).dotnet format style --verify-no-changes --severity=inforeportsFormatted 0 of 31 files.editorconfig-checker(the same container image and invocationvalidate-task.ymluses)passes on the tracked tree; it fails on 79 files under the old
.editorconfig, as expected.Reviewing this diff
git diff --ignore-cr-at-eolreduces the 86-file diff to the 12 files with substantivechanges. Everything else is line endings only.
