# jj-aware statusline for Claude Code
# jj-aware statusline for Claude Code — Synthwave powerline edition
# Receives JSON session data on stdin, outputs a single status line
#
# Layout:
# [Model] bookmark change-id description TRUNK_STATE | N% [2x] status
# Layout (powerline badges with transitions):
# Model bookmark change-id description TRUNK N% 2x status ⚙ countdown
#
# Trunk states:
# @trunk — sitting on trunk
# +N — N changes ahead of trunk (linear)
# ⎇ — divergent (not descended from trunk)
#
# Extras (after context %):
# 2x — Claude March 2026 2x usage promotion is active
# ✓/⚠/✗ — Claude Code status (operational/degraded/outage)
# ⚙ Nd/Nh/Nm — upcoming scheduled maintenance with countdown
# Requires: Nerd Font / powerline-patched font, 24-bit true color terminal
# Palette: Synthwave — all bg+fg pairs meet WCAG AA contrast
