Bot management on downloads.terraphim.ai answers the default Python-urllib User-Agent with 403, which has been failing the hourly r2-manifest-health workflow and local operator runs even though every channel object is healthy. Both fetch paths now send terraphim-r2-manifest-validator/1.0. Verified locally: all three binaries validate legacy=strict=1.21.16 with full size and SHA-256 checks. Refs #337

Problem
The dispatched
r2-manifest-health.ymlrun 36193817261 failed withHTTP Error 403: Forbidden, and the same failure reproduces locally. Cause: bot management ondownloads.terraphim.aianswers the defaultPython-urllibUser-Agent with 403 (verified: same URL returns 200 for curl's UA, 403 forPython-urllib/3.10), so the hourly health workflow has been red independently of channel health.Change
scripts/validate-r2-manifests.pynow sendsUser-Agent: terraphim-r2-manifest-validator/1.0from both fetch paths (manifest load and streamed asset verification). Verified against the live channel after the v1.21.16 promotion: all three binaries validatelegacy=strict=1.21.16with full declared-size and SHA-256 enforcement. Thefile://-based contract tests are unaffected (18/18 pass).Refs #337
