"""Regression anchor: serving artifacts must not block the event loop.
|
|
|
|
``get_artifact`` probes the artifact path (``exists`` / ``is_file``), reads
|
|
text/binary content (``read_text`` / ``read_bytes``), sniffs text-ness
|
|
(``is_text_file_by_content``), and extracts ``.skill`` archive members — all
|
|
blocking filesystem IO. The handler offloads each branch's IO via
|
|
``asyncio.to_thread``; if any regresses back onto the event loop, the strict
|
|
Blockbuster gate raises ``BlockingError`` and these tests fail.
|
|
|
|
The ``@require_permission`` decorator is bypassed via ``__wrapped__`` so the
|
|
anchor exercises the handler's own filesystem IO, not the authz layer. Imports
|
|
sit at module top so any import-time IO runs at collection, outside the gate.
