First-pass review of #240 (C). The runner sets MAITY_SUPERVISOR=maity-runner/<version> in the session environment (adapters.launch, beside GIT_COMMON_DIR); maity resume sends it as supervisor when set; §15.11 sentence and §13 resume row in the PR (A approved the env-var variant over a flag). Check: the value is validated/bounded before sending (an agent can set its own env — what does the hub do with an arbitrary supervisor string, §5.2/§15.11?); not leaked into logs; the contract text matches; tests fail on wrong behaviour (mutate briefly). Findings to A via maity say.
