+### Workflow Optimization: Eliminate Redundant Builds (2026-05-04)
+- **Issue**: PR #274's `squad-preview.yml` had 4 full solution builds: 1 shared `build` job + 3 test jobs each rebuilding everything
+- **Problem pattern**: Separate build job with `needs: build` dependencies = sequential execution + redundant work
+- **Efficient pattern** (from `squad-test.yml`): Each test job restores once → builds only specific test projects → runs tests with `--no-build`
+- **Benefits**: 
+  - Eliminates 3 redundant full-solution builds
+  - Jobs run in parallel (no `needs:` dependencies)
+  - Each job only compiles what it tests (faster)
+- **Concurrency cancellation**: Added `concurrency: { group: ${{ github.workflow }}-${{ github.ref }}, cancel-in-progress: true }` to allow newer pushes to cancel in-progress 45-minute AppHost runs
+- **Squad hygiene**: Reverted unrelated `.squad/` file pollution (PR #276 Azurite work) using `git checkout dev -- .squad/`
+- **Key files**: `.github/workflows/squad-preview.yml`, `.github/workflows/squad-test.yml` (reference)

+# Azure Storage SDK + Azurite Emulator API Version Mismatch Pattern
+
+## Decision
+
+When Azure Storage SDK (Azure.Storage.Blobs) is upgraded and introduces a newer Azure Storage API version that Azurite emulator doesn't yet support, use the `--skipApiVersionCheck` flag to bypass the version check in integration tests until Azurite adds native support.
+
+## Context
+
+- **Problem:** Dependabot bumped Azure.Storage.Blobs from 12.20.0 to 12.27.0 in PR #276
+- **Impact:** Persistence.AzureStorage.Tests.Integration failed with: `The API version 2026-02-06 is not supported by Azurite`
+- **Root Cause:** Azure.Storage.Blobs 12.27.0 uses API version 2026-02-06, but Testcontainers.Azurite 4.11.0 bundles Azurite 3.35.0 which only supports up to 2024-11-04
+- **Azurite Lag:** Azurite emulator typically lags behind Azure Storage service API versions by several months (tracked in Azure/Azurite#2623)
+
+## Implementation
+
+In `tests/Persistence.AzureStorage.Tests.Integration/AzuriteFixture.cs`:
+
+```csharp
+public AzuriteFixture()
+{
+    _container = new AzuriteBuilder("mcr.microsoft.com/azure-storage/azurite:latest")
+        .WithCommand("azurite-blob --blobHost 0.0.0.0 --skipApiVersionCheck")
+        .Build();
+}
+```
+
+## Why This Works
+
+- The `--skipApiVersionCheck` flag tells Azurite to accept any API version without validation
+- This allows integration tests to run with newer SDK versions while Azurite catches up
+- The flag is officially documented in Azurite's command-line options
+- This is the recommended workaround by the Azurite maintainers
+
+## Trade-offs
+
+**Pros:**
+- Unblocks Dependabot PRs for Azure.Storage.Blobs upgrades
+- Maintains test coverage while waiting for Azurite updates
+- Simple one-line fix in test infrastructure
+
+**Cons:**
+- Tests may not catch API-specific behavior differences (new features in 2026-02-06 won't be validated)
+- Masks the version mismatch — team should monitor Azurite releases and remove the flag once native support is added
+
+## When to Revisit
+
+- Check Azurite releases periodically: https://github.com/Azure/Azurite/releases
+- When Azurite adds support for API version 2026-02-06, remove the `--skipApiVersionCheck` flag
+- Consider adding a TODO comment in the code with a link to the tracking issue

+## Related Patterns
+
+- **Testcontainers Command Customization:** Use `.WithCommand()` to pass custom startup arguments to Docker containers in integration tests
+- **Azure SDK Dependency Management:** Monitor Azure SDK upgrades for API version changes that may impact emulator compatibility
