0.23.2 — patch release (no public API change). Merge after the protected-file bundle #420, so the "Detect .NET Projects" guard passes and full CI runs.

Contents (since 0.23.1)

Release mechanics

Order

  1. Merge chore(release): 0.23.2 protected-file bundle (ahead of the release PR) #420 (protected bundle) — admin-bypass.
  2. Merge this PR — full CI.
  3. Tomorrow: tag 0.23.2 + create the GitHub Release → release.yaml → NuGet publish. (Held tonight per one-release-per-day; 0.23.1 shipped 2026-08-17.)

The #346 mutation-test additions introduced 16 fixable InspectCode
findings. Per the .DotSettings policy (fix RedundantCast/S125 in code;
dismiss AccessToModifiedClosure-class per instance):

- RedundantCast x9: drop the `(IProgress<string>)null!` casts in
  OverloadDoubleCoverageTests — each overload set has a single one-arg
  progress method, so `null!` resolves unambiguously (build + 9 tests
  confirm the ArgumentNullException behavior is unchanged).
- S3241 / UnusedMethodReturnValue.Local: CallCreateProgressTimer's
  return is never consumed (3 call sites use it for its wiring side
  effect) -> make it void.
- S125 x5: reword descriptive/Stryker-directive comments to drop the
  code-like tokens (backticks, &&, ConfigureAwait(false), trailing ;)
  that trip the "commented-out code" heuristic. No behavior change; the
  `Stryker disable once Boolean` directive stays functional.

The remaining AccessToModifiedClosure/AccessToDisposedClosure/VSTHRD003
findings are structural false positives on idiomatic test code
(counter closures, a test gate's TaskCompletionSource) and are
dismissed per instance per the documented policy.

chore: clear InspectCode findings in mutation-test code (#361)
Microsoft.Coyote 1.7.11 pulls System.Text.Json 8.0.0 transitively into
tests/Wolfgang.Etl.Abstractions.Tests.Concurrency, which is vulnerable to
CVE-2024-30105 and CVE-2024-43485 (.NET DoS). It is test-only and never
shipped, but it is the sole remaining OSSF Scorecard Vulnerabilities
finding. Pin an explicit 8.0.5 reference (patches both) and regenerate
the lockfile.

fix(security): force System.Text.Json 8.0.5 in the Coyote test project
…Sdk to 18.7.0

Adopts "newest patch, kept consistent" for the first-party Microsoft runtime
packages, and fixes the existing floor drift (Abstractions was 10.0.5 while
TestKit/TestKit.Xunit were 10.0.10).

Shipped src floors -> 10.0.11 (Microsoft.Bcl.AsyncInterfaces, Microsoft.Bcl.Memory,
Microsoft.Extensions.Logging.Abstractions, System.Threading.Channels). On net8+
these are ExcludeAssets=runtime / framework-provided, so the floor only binds
down-level (net462/netstandard2.0) consumers — who now get the latest security
and bug fixes by default.

Cascade fixes (NU1605 package-downgrade) required by the src floor bump:
- 11 examples/Net4.8 projects: direct Microsoft.Bcl.AsyncInterfaces 10.0.5 -> 10.0.11.
- Abstractions.Tests.Unit: Microsoft.Bcl.Memory 10.0.10 -> 10.0.11 (it references
  TestKit, now >= 10.0.11).

Also folded in (was #413, superseded):
- Microsoft.NET.Test.Sdk: net8/9/10 slot 18.3.0 -> 18.7.0 across six test projects
  (older-TFM 17.13.0 blocks intentionally untouched).
- Abstractions.Tests.Unit: System.Linq.AsyncEnumerable 10.0.6 -> 10.0.11.

Lockfiles regenerated. Verified: solution restore clean (no downgrades); all four
src packages pack with PackageValidation passing against the 0.23.1 baseline;
net10.0 517/517 tests pass.

chore(deps): bump first-party 10.0.x deps to 10.0.11 + reconcile Test.Sdk to 18.7.0
…10.32.0.713

Both are minor-version bumps and the Release (TWAE) build is clean across all
TFMs — no new diagnostics to fix. The major-version analyzer bumps (Meziantou,
BannedApi/PublicApi 5.x, VS.Threading 18.x) are handled separately since each
may surface new rules.

Touches the protected Directory.Build.props — merge via admin-bypass.

- Meziantou.Analyzer 3.0.58 -> 3.0.163
- Microsoft.CodeAnalysis.BannedApiAnalyzers 4.14.0 -> 5.6.0
- Microsoft.CodeAnalysis.PublicApiAnalyzers 3.3.4 -> 5.6.0
- Microsoft.VisualStudio.Threading.Analyzers 17.14.15 -> 18.7.23

Full-solution Release (TWAE) build is clean across all TFMs — no new diagnostics
surfaced, including the PublicAPI baseline analyzer (RS0016/17/36/37 still
validate), so no code or baseline changes were needed.

…ml (#386)

Completes the ETL-Abstractions half of #386's phase-1 gate work.

Gate change — per-module threshold in all four coverage-gate implementations
(pr.yaml Stage-1 bash, Stage-2 pwsh, Stage-3 bash; scripts/build-pr.ps1):
unit-test assemblies (name ends in `.Tests.Unit`) must reach >= 99%; every
other assembly keeps CODECOV_MINIMUM (90). Implemented as a single raw-decimal
float comparison; since floor(x) >= N <=> x >= N, src behaviour is unchanged
and only the test-assembly rows get the stricter bar.

release.yaml alignment (step 5): the two coverage-collecting `dotnet test`
calls now pass `--settings coverlet.runsettings`, so release-time coverage
instruments test assemblies the same way PR-time does.

Validated: the bash and pwsh gate logic were run against a synthetic
Summary.txt of boundary cases (test 99.9->pass, 99.0->pass, 98.5->fail;
src 90->pass, 89.9->fail); the current real 99.9% test-assembly coverage
passes. pr.yaml/release.yaml still parse as valid YAML.

Touches protected pr.yaml + release.yaml — merge via admin-bypass. The
repo-template back-port is deferred (ETL-Abstractions-first, per decision).

ci: enforce >=99% coverage on unit-test assemblies + release.yaml alignment (#386)
- <Version> 0.23.1 -> 0.23.2 (patch: no public API change).
- CHANGELOG [0.23.2] section: Changed (10.0.11 dep floors, #415) + Internal
  (analyzer bumps #416/#417; >=99% test-assembly coverage gate + release.yaml
  coverage alignment #386/#418; test-only System.Text.Json 8.0.5 CVE #412).
- PackageValidationBaselineVersion 0.23.0 -> 0.23.1 (last published) on all four
  src packages — the 0.23.1 baseline bump never propagated to main/vNext.

Verified: all four src packages pack with PackageValidation passing against the
live 0.23.1 baseline.

Touches protected Directory.Build.props — merge via admin-bypass.

The >=99% coverage gate (#418) correctly failed the release: CI's merged report
put ErrorPolicies.Tests.Unit and TestKit.Tests.Unit at 98.7%. Two causes:

1. The SDK entry point (AutoGeneratedProgram / Microsoft.NET.Test.Sdk.Program.cs)
   was never actually excluded — coverlet's ExcludeByFile glob doesn't match its
   absolute Windows NuGet-cache path. Exclude it by type name
   (`<Exclude>[*]AutoGeneratedProgram</Exclude>`). Takes ErrorPolicies.Tests.Unit
   to 100% and drops the 1-line SDK gap from every test assembly.

2. The #346 mutation-test helpers. Excluded ONLY genuinely-never-executed code,
   at the MEMBER level (not whole classes), so code that IS tested stays measured:
   - IProgressTimer stub doubles' empty Start(int){}/Dispose(){} (never called) —
     their StopTimer(), which IS asserted on, stays measured.
   - explicit IEnumerator/IEnumerable impls (IEnumerable.GetEnumerator, IEnumerator.
     Current, Reset) never reached through the non-generic interface — the generic
     GetEnumerator/MoveNext/Current that the tests DO drive stay measured.
   - empty-source async iterators passed to pre-cancelled operations that throw
     before enumerating them, so the body never runs.
   Partially-executed helpers (cancel-mid sources) are left measured; their
   unreachable trailing yields honestly remain uncovered.

Result (net10.0): ErrorPolicies.Tests.Unit 100%, TestKit.Tests.Unit 99.7% — both
clear the >=99% gate with only never-executed code excluded.
