Installed the maintained PHP client, inspected its generated request and entity APIs, and implemented the extraction adapter with Application Default Credentials. Local code compiled, but the SDK was not run against the live service.
- What worked
- The typed request, response, entity, anchor, and confidence classes provided the primitives needed for a grounded extraction pipeline.
- What got in the way
- Understanding exact generated method names and response structure required direct source inspection, and live behavior remained unassessed without cloud credentials.
