- Fix bash arithmetic crash on MobaXterm/Cygwin: $(date +%s) was returning CR-tainted values landing in $(( )) operands - Mouse mode off by default; opt in via LARRY_MOUSE=1 or /mouse on - Comprehensive CR-safety sweep across lib/*.sh and larry.sh — every command-substitution result, file read, and user input that feeds an arithmetic context, case dispatcher, or path/header is now CR-stripped at the source New shared helper lib/cygwin-safe.sh defines three primitives: coerce_int VAL [DEFAULT] — for arithmetic / integer-test operands strip_cr VAL — for case patterns, regex tests, paths, headers read_clean VAR [PROMPT] — read -r wrapper that strips CR pre-assign Hardened call sites (14 files, 60+ patch points): - larry.sh: status-line date/tput, 3 y/N approvals, auth menu, API key - lib/oauth.sh: cmd_login + cmd_refresh date+%s captures - lib/nc-engine.sh: 5 y/N action prompts + find|wc arithmetic - lib/nc-msgs.sh: parse_time_ms (4 date sites) + meta-TSV time + MSG_COUNT - lib/nc-regression.sh: tr|wc count + hl7-diff ?-fallback arithmetic - lib/nc-smat-diff.sh: A_COUNT/B_COUNT/DIFFS_TOTAL - lib/nc-insert-protocol.sh: every awk-emitted line number → head/tail math - lib/journal.sh: _next_seq wc -l arithmetic - lib/lessons.sh: _next_id/_count + 2 y/N prompts - lib/hl7-sanitize.sh: cmd_count + clear-table y/N - lib/ssh-helper.sh: 4 local+remote wc -c integer compares - lib/nc-find.sh, lib/nc-table.sh, lib/nc-document.sh, larry-rollback.sh Reproduces the exact error Bryan hit: bash: ...: arithmetic syntax error: invalid arithmetic operator (error token is "") lib/cygwin-safe.sh added to MANIFEST so it auto-syncs on next launch.

# ssh-helper.sh — secure SSH command execution via ControlMaster.
|
||
#
|
||
# Architecture:
|
||
# • Hosts configured in $LARRY_HOME/.ssh-hosts.tsv as
|
||
# alias \t user@host \t port
|
||
# • Passwords stored at $LARRY_HOME/.ssh-creds/<alias>, mode 0600.
|
||
# The password file is the single point of truth — to rotate (daily-changing
|
||
# passwords) just overwrite the file with the new one and re-run 'setup'.
|
||
# • sshpass reads the password via -f (file), so it never lands in argv or
|
||
# environment where Larry the LLM (or other processes via /proc) could see it.
|
||
# • The first 'setup' call opens a long-lived SSH ControlMaster connection
|
||
# (default ControlPersist=8h). Subsequent 'exec' calls multiplex through
|
||
# the master socket and need no password.
|
||
# • Larry's tool layer only sees: alias, command, command_output.
|
||
# Never the password. Never the user@host (unless added to the alias list).
|
||
#
|
||
# Subcommands:
|
||
# hosts list configured hosts
|
||
# add <alias> <user@host[:port]> add a host to the alias list
|
||
# remove <alias> remove an alias (also clears cred + socket)
|
||
# pass <alias> set/update the password (hidden interactive)
|
||
# setup <alias> open ControlMaster (uses stored password ONCE)
|
||
# close <alias> close ControlMaster
|
||
# status [alias] show open masters / cred presence
|
||
# exec <alias> <command...> run command via master (returns output)
|
||
# pull <alias> <remote> [local] scp remote → local via existing master
|
||
# push <alias> <local> <remote> scp local → remote via existing master
|
||
# pull-smat <alias> <site> <thread> [days_back]
|
||
# pull a thread's smatdb (full) or sample
|
||
# recent messages from it (sampled, TSV b64)
