In `@script/generate_openapi_spec.py`:
- Around line 519-536: Update the result-collection loop around result_queue.get
to enforce an overall wall-clock deadline for each plugin, terminating or
reporting a timeout when the worker remains stuck. After process.is_alive()
becomes false, replace the immediate get_nowait() race with a short blocking
read to allow an already-produced result to arrive before reporting “exited
without returning a result”; preserve normal result handling and exit-code
reporting.
- Around line 906-907: The fast path around save_openapi_spec must preserve the
generic pipeline’s EA merge behavior and artifact cleanup, including merging any
existing openapi/ea/openapi.yaml into the root output and removing or otherwise
handling the EA artifact. Align its GA and final artifact generation with the
generic path’s transformations, or retain the generic pipeline instead of
enabling the incomplete fast path.

just a small nit on exception handling, otherwise looks great!

- Around line 565-566: Update the plugin collection handler around the exception
path and its finally cleanup to initialize name, success, and output before
collection begins, set consistent failure values when an exception occurs, and
terminate and join any still-running worker process before closing the queue.
Preserve per-plugin result isolation so later iterations cannot reuse stale
values.

Summary
Speeds up generated-artifact refresh by reducing OpenAPI generator noise, parallelizing plugin OpenAPI extraction more aggressively, cutting repeated OpenAPI file processing in the single-platform case, and generating CLI reference docs from one CLI import. Also fixes the web SDK lint wrappers so they invoke pnpm directly, and caps SDK service generation parallelism to avoid oversubscribing smaller runners.
OpenAPI profiling showed the remaining time was not just platform import: the single platform extraction was about 7s, while the old full refresh spent most of its time in plugin app construction plus repeated schema/file-processing passes. The latest default
make refresh-openapirun is 29.95s, down from 51.15s immediately before this pass and 77s in the originalout.txtrun.Changes
