The tangled pr merge 3mfkhmqrg562f command fails with:
Error: Invalid target repo AT-URI: at://did:plc:meotu43t6usg4qdwzenk4s2t/sh.tangled.repo/3mfkdl5hcvf22
The PR (Objective-C runtime FFI) was merged via git into main and pushed, so the code is correct. But the Tangled PR remains open because the CLI merge command can't parse the target field.
Workaround: The branch was merged locally and pushed to main. The PR should auto-detect the merge, or needs manual closure.
