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.

ptr727 added 4 commits August 29, 2026 20:48
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.
…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.
…packages

xunit.v3 4.0.0 drops the VSTest bridge, so `dotnet test --collect:"XPlat Code
Coverage"` fails outright on the .NET 10 SDK with "Testing with VSTest target is
no longer supported by Microsoft.Testing.Platform". That is what has been
blocking the nuget-deps bumps in #545 and #546, and it blocks every later bump
until the runner moves.

Follow WORKFLOW.md D1.6 as the hub settled it in ptr727/ProjectTemplate#1111,
which chose Microsoft.Testing.Extensions.CodeCoverage over coverlet:

- `global.json` opts into the `Microsoft.Testing.Platform` runner. It carries no
  `sdk` section, so SDK resolution and roll-forward are untouched.
- `xunit.runner.visualstudio` is dropped, the VSTest adapter having no role under
  native MTP.
- `coverlet.collector` becomes `Microsoft.Testing.Extensions.CodeCoverage`
  18.9.0, whose predecessor's VSTest data collector MTP ignores without failing.
  The floor is load-bearing rather than cautionary: below 18.1.0 the extension is
  built against Microsoft.Testing.Platform 1.x and throws a `TypeLoadException`
  against the 2.x platform xunit.v3 4.0.0 carries, running zero tests while still
  writing a well-formed Cobertura file that reports full coverage.
- The CI unit-test step becomes
  `dotnet test --coverage --coverage-output-format cobertura --results-directory ./coverage`,
  then prefixes each report to `coverage-<guid>.cobertura.xml`. Both halves are
  load-bearing and neither reds the job on its own: `--coverage-output` stays
  unset so a second test project could not overwrite the first, and the default
  `<guid>.cobertura.xml` that produces is a name codecov-cli's finder does not
  match, its patterns being `*coverage*.*` and an exact `cobertura.xml`.

Bundle the four 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, and
`xunit.runner.visualstudio` removed rather than bumped to 4.0.0.

`.gitignore` gains the hub's coverage block. The output was untracked and
unignored, so a blanket `git add -A` after a local coverage run would have staged
it.

Verified against the real invocation, not the documented one: 21 tests ran and
passed (not the zero the version-floor trap produces), the extension resolved at
18.9.0 on Microsoft.Testing.Platform 2.3.3, the run wrote
`<guid>.cobertura.xml` and the prefix step renamed it as intended, both filename
shapes are ignored while nothing tracked is, and the build, CSharpier,
`dotnet format style --verify-no-changes`, editorconfig-checker, actionlint,
markdownlint and cspell gates are all clean.
…nfig

Closes the mechanical half of the ProjectTemplate resync. Audit run
`2026-08-30T03:26:30Z | hub a378121`, re-measured against hub f3b4cc9.

- `.github/skills/` (36 files) is a manifest-owned tree, carried with
  `scripts/carry.py apply`. Source and target digests match
  (`c5475deb46bfbf1f9253bc6128a40b7686687597ebe38a6cd1c580a39817f03e`), so it is
  the hub's content byte for byte rather than a hand copy.
- `host-tools.json` is 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; 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, since it
  resolves to a hub-only path.
- `.markdownlint-cli2.jsonc` is verbatim-fidelity, re-vendored whole.
- `.editorconfig-checker.json` takes the hub's `Exclude` list. The entries are
  Python cache directories and inert here, carried whole per the fleet's
  config-carry model.
- `cspell.json` becomes the union of the hub's list, this repo's own domain words
  and the 29 words that existed only in `NxWitness.code-workspace`, which is now
  the single source of truth. The workspace file's `cSpell.words` block is
  removed, per CODESTYLE.md "Markdown and Spelling".

Verified: markdownlint clean across all 45 markdown files (up from 8), cspell
clean, every touched JSON/JSONC file still parses, the workspace file still
parses as JSONC with no `cSpell` key, editorconfig-checker clean, and no tracked
file carries a CR.

Estimated code review effort: 4 (Complex) | ~60 minutes

Merge Risk: 🟡 Moderate · up to 462d2

This PR adds shared repository guidance and configuration, but the carried procedures still include instructions that could permit destructive overwrites or cleanup, unintended release actions, incompatible shell execution, and ambiguous merge authorization. The PR needs fixes or explicit owner acceptance for these bounded operational risks before merge.

Carry Hub Skills and Consolidate Shared Tooling Configuration

AI Description

• Carries the hub-managed skills tree for consistent agent guidance.
• Adds repository host-tool and shared lint configuration overlays.
• Consolidates all spelling terms into the root CSpell configuration.

High-Level Assessment

The chosen approach is appropriate: use the hub carry mechanism for manifest-owned content, retain a tighten-only local host-tool overlay, and centralize spelling terms in cspell.json. Hand-copying skills or retaining workspace-specific spelling words would create avoidable drift and duplicate configuration.

🟢 Approval recommended

Changes are mechanical/configuration-only (carried Skills + lint/spell/host-tool declarations) with no code-path behavior changes identified in the reviewed diffs.

Pull request overview

This PR performs the mechanical half of the ProjectTemplate resync by carrying the hub-owned GitHub Copilot Skills tree into this repo and aligning shared lint/tooling configuration so local/editor and CI checks consume the same sources of truth.

Changes:

  • Carry the hub’s .github/skills/ tree (37 Markdown files) into the repo.
  • Add a repo-local host-tools.json overlay (empty tools list) for host_gate.py layering.
  • Consolidate spelling configuration by moving workspace cSpell.words into cspell.json, plus small shared-lint config updates (.markdownlint-cli2.jsonc, .editorconfig-checker.json).

@ptr727
ptr727 changed the base branch from resync/dotnet-mtp to develop August 30, 2026 21:23
ptr727 added 2 commits August 30, 2026 14:28
Both parents squash-merged into develop, so develop's tree is byte-identical to
this branch's ancestor dc48c3b while carrying different commit ids. Recorded with
the branch's tree, which already contains every one of those changes plus the
conformance carry on top.

Verified before recording: `git diff origin/develop dc48c3b` is empty and
dc48c3b is reachable from this branch, so develop carries nothing this branch
lacks.
`validate-task.yml` declared no `permissions:` block at all, so its job ran with
whatever the repository default grants. That default is `write` here, with
`can_approve_pull_request_reviews` true, so a workflow that only reads the tree
and runs linters and tests held a read/write `GITHUB_TOKEN` on every pull request,
including the smoke path. GOVERNANCE.md "Workflow YAML Conventions" requires least
privilege, and the hub's own copy of this workflow declares `contents: read` on
each of its three jobs.

`contents: read` is sufficient and proven: the hub's lint job runs the same
markdownlint, cspell, actionlint and editorconfig-checker actions under it, and
the Codecov upload authenticates with `CODECOV_TOKEN` rather than the workflow
token.

`test-pull-request.yml` gets the same on the two jobs that own their own steps.
Its `validate` and `smoke-build` jobs are `uses:` calls, and a callee's scope is
granted by the caller, so they take the callee's own declaration rather than one
imposed here.

Raised by CodeRabbit as a merge-risk note on #553, outside that diff and so
carrying no thread. Pre-existing rather than introduced there.

Verified: actionlint, markdownlint, cspell and editorconfig-checker all clean.

Inline comments:
In @.github/skills/carried-instruction-file-guard/SKILL.md:
- Line 17: Update the probe guidance in the carried-instruction file guard so
every hub comparison uses a freshly fetched main checkout immediately before the
probe. Align this requirement with the existing fresh-checkout behavior
referenced by copilot-instructions-keeper, rather than permitting reuse of an
arbitrary existing checkout.

In @.github/skills/code-review/SKILL.md:
- Around line 17-22: Update the sibling-skill list in the review skill
instructions to include operational-vs-release-workflow, and direct applicable
branch or publishing reviews to load branch-protection-and-promotion.md or
release-publish-mechanics.md according to the documented change type.

In @.github/skills/comment-and-doc-style/references/line-endings.md:
- Around line 69-75: Update the byte-preserving directory guidance near the
`.editorconfig` override to require a matching `.gitattributes` rule using
`<dir>/** -text` or `binary`, preventing the global `* text=auto eol=lf` rule
from normalizing text-like files. Keep the existing editor settings for
disabling all normalization.

In @.github/skills/copilot-instructions-keeper/SKILL.md:
- Around line 54-55: Require downstream content to be preserved, promoted, or
relocated before any re-vendoring overwrites it: in
.github/skills/copilot-instructions-keeper/SKILL.md lines 54-55, limit updates
to hub-owned sections and preserve or relocate other local sections; in
.github/skills/resync-a-repo/SKILL.md lines 63-65, stop processing modified
findings until their content is promoted or preserved.

In @.github/skills/drive-pr/SKILL.md:
- Around line 46-47: Update the drive-pr skill’s merge authorization guidance so
naming the skill or answering its how-far question is not treated as approval.
Require an independent, explicit maintainer authorization check before Step 4
executes gh pr merge --squash, consistent with AGENTS.md.

In @.github/skills/fleet-conformance-check/SKILL.md:
- Around line 36-39: Update the conformance checks in the fleet-conformance
skill to validate that CLAUDE.md exists and contains the required fixed
`@AGENTS.md` import, using the baseline defined by standup-a-repo/SKILL.md;
otherwise narrow the stated conformance claim so it does not imply CLAUDE.md is
covered.

In @.github/skills/git-commit-conventions/references/history-rewrite.md:
- Around line 3-10: Correct the history-rewrite guidance to state that git
filter-repo removes signatures from rewritten commits rather than re-signing
them. Document an explicit post-rewrite signing step, then require verification
of every rewritten commit before pushing to a branch protected by signed-commit
rules.

In @.github/skills/git-commit-conventions/SKILL.md:
- Line 80: Update the sign-check probe to validate the commit email against the
authenticated account’s exact valid ID-based or username-based noreply address,
rather than accepting any address ending in `@users.noreply.github.com`; apply the
same account-specific check to both author and committer email comparisons while
preserving signature validation.
- Line 80: Update the sign-check probe to validate the target repository’s
effective configuration rather than only global user.email: initialize or
inspect the target repository context and resolve local overrides for
user.email, commit.gpgsign, gpg.format, and user.signingkey before the git add
gate. Ensure the validation reflects the identity and signing behavior that an
actual target commit will use, while preserving the existing rejection behavior
for unsigned or disallowed identities.

In @.github/skills/merge-and-release/SKILL.md:
- Around line 204-207: Update the branch-deletion workflow around the headRefOid
verification, local git branch -D, and remote git push origin --delete steps so
deletion proceeds only if the branch tip still matches the verified OID. Use a
supported atomic compare-and-delete operation where available; otherwise recheck
the ref immediately before each deletion and stop with a clear report if it
changed, preserving the existing prohibition on force-with-lease.
- Around line 70-75: Update the releaseTrigger validation in step 5 to accept
only the four documented values: none, two-phase, dispatch-only, and
publish-on-merge. Treat an omitted or null value, along with any unknown value,
as invalid and stop without dispatching; preserve the existing no-release
behavior for none and dispatch behavior for the three configured modes.

In
@.github/skills/operational-vs-release-workflow/references/branch-protection-and-promotion.md:
- Line 38: Update the branch comparison guidance around the normalized diff
command to verify that develop contains all main changes before using git
checkout --theirs; do not treat any nonzero diff as sufficient. Use an explicit
superset check, and direct ambiguous or main-only differences to manual conflict
resolution instead of discarding content.
- Around line 107-109: Update the version guidance in the
create-github-app-token section to state that client-id is supported starting
with v3.1.0, making v3.1.0+ the minimum for that input; preserve the existing
instruction to use client-id and not reintroduce app-id or CODEGEN_APP_ID.

In @.github/skills/python-codestyle/references/profiles.md:
- Around line 5-8: Update the default Python profile description to say
“development dependencies in [dependency-groups]” while preserving the existing
statement that runtime dependencies belong in [project].dependencies.

In @.github/skills/repo-worktree/SKILL.md:
- Around line 175-177: Update the continuation rule for returning a shared
checkout from task-branch so a clean working tree alone is insufficient; require
positive proof of ownership or explicit approval before switching branches, and
otherwise stop and use an independent clone.

In @.github/skills/shell-codestyle/SKILL.md:
- Around line 41-48: Separate the shell guidance into Bash and POSIX sh
patterns: keep set -Eeuo pipefail and BASH_SOURCE requirements only for scripts
identified as Bash, and provide portable POSIX sh guidance without those
features. Update the relevant shell-codestyle sections while preserving the
existing Bash requirements.

In @.github/skills/standup-a-repo/SKILL.md:
- Around line 82-83: Update the repository configuration workflow around the
check and apply commands so a non-zero check result triggers apply only when the
check completed successfully and explicitly reported drift. Preserve failure
handling for recorded API errors in check_security and check_secrets and for
other command failures, preventing apply after an incomplete or failed check.

In @.github/workflows/test-pull-request.yml:
- Around line 110-111: Set workflow-level permissions to empty, retain contents:
read only for the changes, validate, and smoke-build jobs, and set
check-workflow-status permissions to empty while preserving its needs-result
checks and shell commands.

Refines the previous commit per review. A per-job block hardens the jobs that
exist; it does nothing about the next one added, which would silently inherit the
repository default of write. `permissions: {}` at the workflow level makes the
default nothing, so a new job grants what it needs or gets none.

That inverts the requirement for the two `uses:` jobs, which now need the caller
to grant at least what the callee declares, so `validate` and `smoke-build` carry
`contents: read` explicitly. Both chains only check out the tree: Docker Hub
authentication uses `DOCKER_HUB_USERNAME` and `DOCKER_HUB_ACCESS_TOKEN` rather
than the workflow token, and the smoke caller passes `push: false`.

`check-workflow-status` drops to `permissions: {}`. It reads `needs.*.result` and
runs shell, and touches no GitHub resource at all.

Verified: actionlint clean. This pull request exercises `changes`, `validate` and
`check-workflow-status`; it changes no image file, so `smoke-build` skips and its
tightening is reasoned from the callee's steps rather than observed here.

🔵 Needs a closer look

The updated workflow/skill contract expects set -Eeuo pipefail in multi-line bash steps and the diff still leaves some steps using set -euo pipefail, plus the spell-check docs reference in AGENTS.md becomes inaccurate after removing workspace-local words.

Review details

Suppressed comments (4)

Previously missed (4) — in code that hasn't changed since the last review.

.github/workflows/validate-task.yml:26

  • The new workflow CI contract skill states that every multi-line bash run block should start with set -Eeuo pipefail, but the Check code style step still uses set -euo pipefail. Aligning this keeps the workflow consistent with the carried contract and ensures ERR traps propagate into functions/subshells if they get added later.
    .github/workflows/test-pull-request.yml:38
  • The carried workflow CI contract requires multi-line bash run blocks to start with set -Eeuo pipefail, but the Filter changed paths step still uses set -euo pipefail. Since this workflow is already being touched, it would be good to make the run header match the contract to avoid future style drift.
    NxWitness.code-workspace:10
  • This change removes the workspace-local cSpell.words list (moving words to cspell.json), but AGENTS.md currently states that spell-check words live in NxWitness.code-workspace. That statement becomes inaccurate after this PR, so it should be updated in the upcoming instruction-set/split PR (or otherwise reconciled) to avoid confusing contributors.
    .github/workflows/test-pull-request.yml:119
  • The carried workflow CI contract requires multi-line bash run blocks to start with set -Eeuo pipefail, but the aggregator's Check workflow results step still uses set -euo pipefail. Updating it keeps the workflow consistent with the newly carried contract.

… contract

Carrying the skills tree brought a contract this repo did not meet.
`workflow-ci-contract/SKILL.md` requires every multi-line bash `run:` to start
`set -Eeuo pipefail`, while `WORKFLOW.md` stated `set -euo pipefail` and 12 of the
13 blocks used it. The one exception was the unit-test step added with the runner
migration, copied from the hub, so the file was inconsistent with itself as well.

All 13 blocks now use `set -Eeuo pipefail`, and `WORKFLOW.md`'s shell convention
and D9.3 say the same. `-E` makes an ERR trap inherit into functions and
subshells; there is no `trap` anywhere in `.github/workflows/`, so this changes no
behavior today and guards the case where one is added later.

`AGENTS.md` still said spell-check words live in `NxWitness.code-workspace`. This
pull request is what made that false, by folding that list into `cspell.json` and
deleting the workspace copy, so the sentence is corrected here rather than left
for the file that later removes the whole section.

Verified: actionlint clean, markdownlint clean, and every `run:` block in the tree
now matches the carried rule.

Answering the four suppressed findings from round 4 here, since a suppressed finding opens no thread to resolve. All four accepted, fixed in f398db9.

The carried workflow CI contract requires multi-line bash run blocks to start with set -Eeuo pipefail, but the Filter changed paths step still uses set -euo pipefail.

Three of the four were this, against validate-task.yml:26, test-pull-request.yml:38 and test-pull-request.yml:119. The finding is right and understates the scope, so I swept the tree rather than the three lines reached.

This is a conflict this pull request created. Carrying the skills tree brought workflow-ci-contract/SKILL.md:26, which requires set -Eeuo pipefail, into a repo whose own WORKFLOW.md:95 and D9.3 stated set -euo pipefail, and where 12 of 13 blocks used it. The 13th was the unit-test step added with the runner migration, copied from the hub, so validate-task.yml disagreed with itself. Leaving it would have meant carrying a contract the repo violates in twelve places.

All 13 blocks across the eight workflow files now use set -Eeuo pipefail, and WORKFLOW.md's shell convention and D9.3 say the same, so the carried rule and the repo's own statement of it agree.

On risk: -E makes an ERR trap inherit into functions and subshells. grep -rn "trap " .github/workflows/ returns nothing, so this changes no behavior today and only guards the case where a trap is added later. actionlint is clean.

This change removes the workspace-local cSpell.words list (moving words to cspell.json), but AGENTS.md currently states that spell-check words live in NxWitness.code-workspace.

Correct, and this pull request is what made it false. Fixed here rather than deferred: the sentence now sends editor settings and extension recommendations to the workspace file and spell-check words to cspell.json. #551 later removes that whole section as part of the AGENTS.md split, but deferring would have left develop carrying a false statement in the window between the two merges, which is exactly the window this pull request opens.

11 checks passed
ptr727 added a commit that referenced this pull request Aug 30, 2026
A real merge rather than the `-s ours` the two earlier reconciles used. Those were
safe because develop reproduced an ancestor of the branch exactly; this one is
not, because #550 gained work after this branch forked from it, so develop now
carries content this branch lacks. Checked before choosing: `git merge-base
--is-ancestor f398db9 HEAD` fails.

Ten conflicts, resolved by what each side actually owns.

`WORKFLOW.md` needed both sides and is the only genuine interleave. This branch
repointed the retired `repo-config` references and anchored the Release Model
pointer; develop tightened the shell header to `set -Eeuo pipefail` in the
convention and in D9.3. Each hunk took the side that changed it, so the file now
carries all four.

`cspell.json` is the union. develop's 216 words turned out to be a strict subset
of this branch's 230, the difference being the words the newly carried prose uses,
so nothing was dropped in either direction.

The four `repo-config/` files were deleted here and only line-ending-normalized on
develop, so the deletion stands. That retirement is this branch's purpose.

`AGENTS.md`, `CODESTYLE.md`, `.github/copilot-instructions.md` and
`NxWitness.slnx` take this branch's version. Verified first that nothing
develop-only is lost: the last two have no content change on develop at all, and
develop's two `AGENTS.md` changes both landed in sections this split moves, whose
replacements in `OPERATIONS.md` already say the same thing or better. `CODESTYLE.md`
already carries develop's line-ending item verbatim.

Verified after: all 13 `run:` blocks still carry `set -Eeuo pipefail`, both
permissions-hardened workflows keep their blocks, the skills tree is intact,
`repo-config/` is gone, the solution builds, and markdownlint, cspell, actionlint
and editorconfig-checker are clean.

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.

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.
