Catch a service worker update between two page loads
Test waiting workers, mixed asset versions, cache cleanup, and recovery.
Readiness check
Is the handoff ready?
Use this table before you send the first ticket. Fix the weak spots while access is still limited.
| Area | Ready | Needs work |
|---|---|---|
| Question | One observable service-worker updates outcome | A request to inspect the whole system |
| Fixture | a test origin with two labelled builds and clean browser profiles | Customer data or shared credentials |
| Evidence | page build, worker state, cache names, asset response, reload path, and recovery | A pass label without observed values |
| Approval | The web owner approves activation policy and production release. | The contractor changes production alone |
Reproduce the service-worker updates failure safely
A page can run new code against old cached assets or retain a broken worker. Start with one case that can fail without touching customer records or production infrastructure. Write the expected result, stop condition, and reviewer beside the fixture.
Use a test origin with two labelled builds and clean browser profiles. Label every identity and artifact so a reviewer can distinguish test evidence from a live record.
Leave enough evidence for a second person
Capture page build, worker state, cache names, asset response, reload path, and recovery. Include the source revision and test time. If behavior changes between runs, retain both results.
The web owner approves activation policy and production release. A remote programmer can prepare the fixture, run bounded checks, and explain the result. New policy, privileged access, and release approval stay with the named owner.
