fix: unblock promotion after an interrupted run — resume + runner-owned evidence
The two defects that stopped c43e's already-passing host gate: - promote refused its own leftovers: the runner writes host-gate records and skill-use receipts into the base between runs, so run N+1 was blocked by run N's artifacts. runner_owned_promotion_path now accepts those for any run id, shape-matched to the runner's own filenames — nested paths, traversal, foreign extensions, and every user-source path are still refused. - resume deadlock: after that refusal the supervisor's --resume re-required a verifier node the same run had already marked succeeded, which 'ready' correctly never re-offers, so the run spun restarts until HALTED. verifier_gate_admits treats already-succeeded-this-run as admitted; all other states still fail closed. tests: test-promote-scope.sh (21), test-verifier-resume.sh (9). Suite 4110/0. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
