# twohost-ladder-local.sh — run BOTH roles of crates/spt-daemon/tests/twohost.rs (the LADDER)
# on ONE box (peer ip 127.0.0.1) as gate leg 9b's witness. Sibling of twohost-web-local.sh,
# parametrized on the TEST binary rather than hardcoding it (doyle ruling 2026-09-08 10:37Z).
#
# Why it exists: XFER retirement (#246) rewrote the ladder's cross-host side-channel — B's
# drive sid, B's B-2 ticker sid and A's completion barrier moved off the retired transfer
# family onto replicated notif rows (SID_SIGNAL / SID2_SIGNAL / LADDER_DONE). A rewritten
# cross-host barrier that no leg runs is UNWITNESSED by construction.
#
# usage: twohost-ladder-local.sh <worktree> <label> [test-binary]
# Writes <worktree>/.spt/twohost-ladder/<label>/{build,b,a}.{raw,exit}
# Identity trio + SPT_HOME are scrubbed for every child (a perch-launched battery inherits the
# endpoint identity and every daemon-stopping arm refuses — memory 2026-09-06).
