Docs: select the SDMA tests by marker in the testing skill's recipe

[ChaoWao]

Summary

Follow-up to #1609 and #1617 — the same two defects, in the file whose stated purpose is reproducing CI.

1. The recipe contradicted the instruction three lines above it. The skill says quarantines "are markers on the tests, so mirror the sweep with -m "not sdma" rather than copying a path list" — and then the command block copied a path list:

pytest examples/a2a3/tensormap_and_ringbuffer/sdma_async_completion_demo \
       examples/a2a3/tensormap_and_ringbuffer/prefetch_async_demo

That is exactly the fragility #1609 removed from ci.yml. It is now pytest examples tests/st -m sdma — the same corpus and the same selector as the workflow's SDMA_TESTS, so the recipe cannot drift from the job it mirrors.

2. "Their own devices" is aarch64-only, in three places (prose, the quarantine table's "runs instead in" cell, and the command comment). Only the aarch64 branch gives the SDMA step task-submit --device auto --device-num 2; x86_64 has no task-submit and both steps use ${DEVICE_RANGE}. What holds on both is ordering — SDMA runs after the sweep, so no fault-injection case meets a device that has already provisioned SDMA. Same correction #1617 made to docs/ci.md.

Testing

• Both recipes now match ci.yml verbatim in corpus and selector: sweep examples tests/st -m "not sdma", SDMA step examples tests/st -m sdma (ci.yml:627)
• No hardcoded demo path remains in any command; the demo names survive only in the table's "Excludes" column, which describes what the marker covers rather than being copied
• .claude/ is in NON_CODE, so every gated job should report skipping

📝 Walkthrough

Walkthrough

The testing skill updates SDMA quarantine guidance. It documents marker-based exclusion from the general sweep and a dedicated post-sweep -m sdma run on two devices.

Poem

A rabbit reads the markers bright,
SDMA hops beyond the sweep tonight.
Two devices wait in a later run,
The testing guide now matches CI’s plan.
“Binky!” says the rabbit, “The path is clear!”
