#

# wrap can retry within the same session once the tree is clean. But nothing
# bounded that to the session: the sentinel outlived it and detonated in
# whatever session next happened to have a clean tree. work's 11:37 wrap left
# one armed; the 13:20 session committed during startup, went clean, and was
# torn down mid-work. archsetup's had been armed for two days on a live
# terminal.
#
# A new session means the wrap that armed the sentinel is gone, so its pending
# teardown is moot. session-start-disarm.sh clears it.
