# Release regression QA recipes

Check upgrades, feature flags, migrations and compatibility using recorded revisions, stable acceptance criteria and recoverable environments.

Keep the release candidate and fixture revision together. Compare behavior against approved requirements and retain original failure artifacts during repairs.

## Pages (10)

- [Verify a cached application shell survives candidate assets](https://vostride.com/agent-library/release-regression/cached-shell-loads-new-chunk.md): Test an externally prepared cached sandbox shell after a release, checking lazy navigation recovery and build consistency when assets have changed.
- [Verify candidate configuration stays inside the sandbox](https://vostride.com/agent-library/release-regression/configuration-target-isolation.md): Inspect a candidate release in an owned sandbox to confirm displayed environment identity and a harmless write both resolve to the intended isolated target.
- [Verify a candidate workflow persists across browser engines](https://vostride.com/agent-library/release-regression/cross-browser-saved-workflow.md): Test a sandbox record authored in one browser and read in another, separating browser-specific interaction failures from shared data persistence.
- [Verify disabling a feature preserves existing records safely](https://vostride.com/agent-library/release-regression/feature-flag-off-with-existing-data.md): Test a sandbox release feature flag with previously created feature data, checking documented access, fallback navigation, and unchanged stored content.
- [Verify a release check detects its known broken control](https://vostride.com/agent-library/release-regression/known-failure-control-verdict.md): Evaluate a release regression test against externally prepared correct and broken sandbox builds, ensuring its verdict depends on the required outcome.
- [Verify legacy permalinks reach the same record after release](https://vostride.com/agent-library/release-regression/legacy-permalink-destination.md): Test saved sandbox record links across a route change, checking exact destination identity, preserved query intent, and a useful missing-record outcome.
- [Verify a release permission migration preserves account boundaries](https://vostride.com/agent-library/release-regression/permission-migration-retains-boundaries.md): Test sandbox roles after a prepared release migration, checking one allowed action and one forbidden path against independently recorded grants.
- [Verify a previous client works with the candidate server](https://vostride.com/agent-library/release-regression/previous-client-new-server.md): Test an externally prepared previous-version client against a candidate sandbox server, checking a real edit journey and the saved record contract.
- [Verify candidate workers process previously queued jobs](https://vostride.com/agent-library/release-regression/queued-job-old-payload.md): Test an externally preserved sandbox job created by the previous release, checking candidate worker compatibility and the resulting user-visible record.
- [Verify a prepared rollback can read candidate-created data](https://vostride.com/agent-library/release-regression/rollback-reads-newly-created-record.md): Check an externally rolled-back sandbox release against records created by the candidate, verifying readable detail and supported edits after rollback.

## Apply a recipe

These are test designs to adapt to an application's acceptance criteria and fixtures. They are not recorded runs or a claim that a listed application has been tested. Use the [recipe execution guide](https://vostride.com/agent-library/software-factory/turn-a-recipe-into-an-agent-qa-test.md) to author, validate, run and inspect a test.
