Carom invites contributions on eleven open issues and had no CI at all: the only workflows were a dispatch-only publish, self-assign and solicitation flagging. So a well meant first pull request could break every consumer with nothing to catch it. This adds the missing gate and the pipeline to run it.

Standard being applied: DELIVERY.md, specifically a machine-checked record of the public surface and protection with no check is a turnstile.

What this adds

A public API approval test covering all seven packable projects, using the same PublicApiGenerator pattern already proven in Verdict. When the surface changes the test fails with a readable diff and quotes the versioning rule back: additions are a minor, anything removed or changed in place is a major.

A CI workflow. Restore, build, test and pack the whole solution on every pull request, in Release, because Release is what ships. It asserts a floor of 250 tests and that total equals passed, since a run that discovers nothing exits zero and would otherwise go green while proving nothing.

Three things found while doing it

Three published packages were absent from Carom.sln (issue #10): Carom.AspNetCore, Carom.EntityFramework and Carom.Telemetry.OpenTelemetry. They are on NuGet at 1.5.0 and were never built or tested by anything. Referencing them from the approval project pulled them in, and dotnet sln add brought the rest. Closes #10.

Carom.Examples.WebApi was packable. dotnet pack on the solution produced a Carom.Examples.WebApi package from sample code. It is not on NuGet, so no harm has been done, but any publish step iterating the solution would have pushed it. Marked IsPackable=false.

The repo's versions are behind NuGet. The csproj files say 1.0.0, 1.3.0 and 1.4.0; NuGet has 1.5.0 for six packages. So the source tree does not describe what shipped, and Carom.DependencyInjection is packable but has never been published at all. Not fixed here because it needs a decision about where versions live, but it should not stay this way: the approval test's versioning advice assumes the number in the repo means something.

Verification

Seven approved surfaces generated and committed. The suite passes at 7 of 7.

Proven by mutation, not asserted: removing one line from Carom.Http.approved.txt fails exactly that one test and reports

Added (1):
  + public static IHttpClientBuilder AddCaromResilience(this IHttpClientBuilder builder) { }

so it detects the change, names the member and classifies it correctly.

The full solution builds and packs in Release: seven packages, examples excluded.

Note on runtime

The test job has a 30 minute timeout because the suite currently takes around twelve minutes, nearly all of it in one test that uses 100 retries with no base delay so jitter saturates toward the 30 second cap. That is issue #11, and it is worth fixing before this becomes a required check on every pull request.

Summary by CodeRabbit

  • New Features

    • Added resilience tools for retries, timeouts, circuit breakers, fallbacks, throttling, rate limits, bulkheads, and hedging.
    • Added integrations for ASP.NET Core health checks, HTTP requests, Entity Framework operations, dependency injection, and OpenTelemetry diagnostics.
    • Added configurable synchronous and asynchronous execution with cancellation and timeout support.
  • Quality Improvements

    • Added automated public API compatibility checks and continuous test validation.
    • Expanded solution coverage for resilience components and integrations.
    • Improved package validation and excluded the Web API example from package creation.

📝 Walkthrough

Walkthrough

The change adds API approval tests, approved public API snapshots for seven Carom assemblies, solution wiring, CI build and test validation, TRX upload, Release packaging, and exact package-set validation.

Changes

Build and API coverage

Layer / File(s) Summary
Solution and packaging wiring
Carom.sln, examples/Carom.Examples.WebApi/Carom.Examples.WebApi.csproj
The solution includes the API approval test project with configuration mappings and test-folder nesting. The Web API example is marked non-packable.
Core resilience API contracts
tests/Carom.ApiApproval.Tests/ApprovedApi/Carom.approved.txt, tests/Carom.ApiApproval.Tests/ApprovedApi/Carom.DependencyInjection.approved.txt, tests/Carom.ApiApproval.Tests/ApprovedApi/Carom.Extensions.approved.txt
Approved snapshots define retry, pipeline, registry, resilience extension, builder, state, and exception APIs.
Integration API contracts
tests/Carom.ApiApproval.Tests/ApprovedApi/Carom.AspNetCore.approved.txt, tests/Carom.ApiApproval.Tests/ApprovedApi/Carom.EntityFramework.approved.txt, tests/Carom.ApiApproval.Tests/ApprovedApi/Carom.Http.approved.txt, tests/Carom.ApiApproval.Tests/ApprovedApi/Carom.Telemetry.OpenTelemetry.approved.txt
Approved snapshots define the ASP.NET Core, Entity Framework, HTTP, and OpenTelemetry APIs.
API approval test harness
tests/Carom.ApiApproval.Tests/Carom.ApiApproval.Tests.csproj, tests/Carom.ApiApproval.Tests/PublicApiTests.cs
The test project references seven Carom assemblies. PublicApiTests generates normalized APIs, compares snapshots, manages received files, and reports bounded diffs.
CI validation and packaging
.github/workflows/ci.yml
CI restores and builds the solution, runs Release tests, requires at least 250 passing tests, uploads TRX results, and validates the exact package set.

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

Merge Risk: 🟡 Moderate · up to 7d3bd

The new CI workflow runs repository-controlled build and packaging commands with checkout credentials still available, creating a bounded security exposure, and its packaging checks can pass without proving that all required packages are produced or that the Web API example is excluded. Merge should wait until these issues are fixed or explicitly accepted by the owner.

🚥 Pre-merge checks | ✅ 2 | ❌ 3

❌ Failed checks (3 warnings)

Check name Status Explanation Resolution
Linked Issues check ⚠️ Warning Issue #10 is not satisfied because the changes add only Carom.ApiApproval.Tests to Carom.sln, not the three required published projects under src. Add Carom.AspNetCore, Carom.EntityFramework, and Carom.Telemetry.OpenTelemetry to Carom.sln under src with all required platform configuration rows.
Out of Scope Changes check ⚠️ Warning The API approval baselines, CI workflow, and example packaging change are unrelated to the linked issue #10 solution membership requirement. Split unrelated CI, API approval, and example packaging changes into separate pull requests or link issues that define their objectives.
Docstring Coverage ⚠️ Warning Docstring coverage is 0.00% which is insufficient. The required threshold is 80.00%. Write docstrings for the functions missing them to satisfy the coverage threshold.

arnelirobles force-pushed the test/public-api-approval branch from 2471057 to bac352d Compare August 18, 2026 03:14
four test assemblies plus a fixed LogFileName means one surviving
file, so the count gate saw 196 of 295 and failed. verified locally:
four trx files, 295 total.
ls -la passes whenever any package exists, so a missing package or a
newly-packable example both went green. this branch exists to make
the set exactly right, so check the set. mutation tested five ways.

also read-only token and persist-credentials false: no step runs an
authenticated git or gh command.
