post(devops): it reported success, nothing had changed (EN+ZH) + og/banner

Three silent failures on a network-mounted share: a 403 MB upload that wrote 12.5 MB and returned OK
(the timeout toast arrived minutes later, asynchronously), an os.replace() that never landed while
getsize()/mtime served cached metadata (the destination was still the original H.264 file), and a
byte-count source check that agreed with a length-preserving bad copy. Adds read-back hashing at all
three boundaries (source copy, upload, install) and records the metric traps that hid them: a clean
decode test on wrong pictures, SSIM on near-flat frames, input-seek decoding of open-GOP sources,
stream-copy slices dropping frames, and fixed-name scratch files colliding across concurrent runs.
Audit after the fix: reported=30 landed=29 not-landed=0.
