The field wave's residual gaps are closed. v1.91.96.0 through v1.91.100.0 shipped the install-honesty and unattended-`/autoplan` wave (`docs/designs/GSTACK_FIELD_WAVE_2026_10_12.md`); running that release on a Capy machine left six gaps, each reproduced here with a test that failed first.

# gstack-harness-pid.sh — the harness pid behind a gstack command (sourced,

# never executed). One derivation for every writer that keys per-session
|
|
# state on it: bin/gstack-skill-start (the state-root session marker) and
|
|
# bin/gstack-lease (the install-scoped workflow lease), so an updater that

# reads leases sees the same pid the session wrote. Bash 3.2 plus ps.

# gstack_harness_pid START — walk up from START (the calling shell) past

# shell wrappers and print the first non-shell ancestor. Claude Code runs a
|

# tool call under a per-call `bash -c`, whose parent is the harness; a host
|
|
# that execs the command directly is already the parent. Without a usable ps
|
|
# (some Windows shells) START stands. At most 8 hops; pid 0 and 1 stop.
