Verified on this PR's own run rather than merged on the reasoning.
Across all 15 devices in the matrix:
```
Stage artifacts 15 success
Upload build artifacts 15 success
Send binary 15 skipped
Publish releases skipped
CI Gate success
```
15 `fw-*` artifacts produced, and the retention the fix was about is what
actually landed:
```
fw-hi3516ev300_ultimate_rvi-1ncmw2028
created 2026-08-27T21:17:00Z
expires 2026-09-03T21:16:58Z -> 7 days
```
So a pull request now keeps the images it built, for a week, while the two
paths that must stay closed to a PR -- the Telegram secret and shared release
assets -- are still closed.
