Shared _sanitize_ctl (unconditional, nc-document) and _sanitize_ctl_tty
(strips only when stdout is a terminal) now live in cygwin-safe.sh. nc-msgs,
nc-parse, and the hl7-* tools route stdout through the tty-gated variant, so a
terminal is protected from raw HL7/NetConfig control bytes while pipes and
redirects stay byte-exact (the 0x1c framing route_test needs is preserved).
Exit codes propagate via PIPESTATUS. ssh-helper _read_hidden installs its
restore trap before stty -echo on every path and saves/restores the prior trap.

nc-parse.sh
+ chain <name> [--depth N] [--direction both|up|down]
BFS over sources+destinations from a starting thread; returns the
reachable cluster as TSV (depth, direction, thread).
nc-msgs.sh
+ Filter operator additions:
> >= < <= numeric or lexical (works for HL7 YYYYMMDDHHMMSS timestamps)
>< range "LO..HI" inclusive
+ Filter group additions:
--field AND group (must match; existing behavior)
--or-field OR group (at least one must match)
--not-field NOT group (none may match)
All three groups combine; bug fixed where empty AND group bypassed
OR/NOT checks in the count format.
+ SmatHistory walk:
--include-history also walks $HCISITEDIR/exec/processes/*/SmatHistory/
--all cheat-sheet alias for --include-history
Confirmed working against the real ancout test data:
- chain IB_ADT_muxS finds all 7 downstream destinations
- event=A08 OR event=A03 → 20 (19+1 of 22)
- visit>400000000 → 22 (all numeric in range)
- visit><400000000..400450000 → 22 (range inclusive)
- --include-history → 22 active + 34 history rows = 56 total
