# /greendot — mark a Claude session's iTerm2 tab GREEN = "WORKING — running or monitoring, nothing needed from Steve".
# A fixed SEMANTIC color (not /color's rotating golden-angle hue): green always means
# "this session is WORKING or monitoring — nothing is needed from Steve." The default resting state.
# Steve, 2026-09-02: every window always shows exactly one dot; green closes the "no dot" gap.
# Sibling of /yellowdot (needs direction), /purpledot (gated memo), /orangedot (paste in terminal),
# /pinkdot (parked).
#
# Mechanism (shared with all dot painters via paint-lib.sh): the Claude Bash tool runs with NO
# controlling tty, so OSC escapes on stdout never reach the terminal. We resolve the OWNING `claude`
# process's pty by ancestry and write the OSC straight to /dev/ttysNNN — in a SINGLE atomic write so
# it can never be torn mid-sequence. Two hard safety rails (see paint-lib.sh header for the proven
# root cause): (1) refuse to paint from a subagent — a subagent's ancestry resolves to the PARENT
# session's pty, so painting would corrupt Steve's live pane; (2) no background pulse loop — the old
# rapid-fire loop is what leaked the OSC payload ("1;bg;green;brightness;0") into the Claude input.
#
# Usage:
#   greendot.sh                 # green-dot THIS session (title "🟢 WORKING")
#   greendot.sh "TK-11098 x3"   # green tint + custom title text (🟢 prefixed) — put the TK + count
#   greendot.sh --all           # green-dot EVERY live claude tab (rare)
#   greendot.sh --off           # clear the tint on THIS session
set -u

# HARD RAIL: a subagent has no tab of its own; painting would write to the parent session's
# live pane (the input-field-pollution bug). Refuse and no-op.
