Delete branch "agent/roster-stale-member-20260819"
Deleting a branch is permanent. Although the deleted branch may continue to exist for a short time before it actually gets removed, it CANNOT be undone in most cases. Continue?
Why
An exact remote candidate can become obsolete while it builds because one PR head moves. Today the dispatcher returns a generic infrastructure failure, so the stable peers retry with the obsolete member until the entire roster is infrastructure-ejected for one hour.
What
RosterStalelane outcomeVerification
No local build was run. Forgejo CI is the compilation and test authority. Added pure policy and real-dispatch subprocess coverage for valid and malformed protocol paths.
Superseded by #160, which pointed to the exact same commit/tree and merged normally. Forgejo had cached #158 as conflicting even though its update endpoint reported the head already up to date and git merge-tree was clean.
