# mcode-status — z.ai GLM 5-hour usage segment for the MiniMax Code statusline.
#
# Output (one line, Aygea palette):
# 🔥 23% · 4:12p(2h14m) (+ optional 🧠 mem segment, see AYGEA_SL_MEM)
#
# Registered in ~/.minimax/config.yaml as tui.customStatusLine.command with
# colorMode: ansi. MiniMax Code re-runs it every intervalSeconds and renders
# stdout as the "custom-command" item — mcode is the scheduler, so there is
# NO cron/systemd dependency. Network refreshes happen in a detached,
# flock-guarded background job; the statusline call itself never blocks.
#
# Credentials (checked in order):
# 1. SecretVault secret $AYGEA_SL_SECRET_NAME (default zai_api_key) via
# `secretvault run` — the public-repo-safe path. Endpoint defaults to
# https://api.z.ai (override with AYGEA_SL_URL).
# 2. Legacy ~/.secretvault/credential.json (url + clientKey, the Aygea
# Claude-statusline layout) → endpoint ${url}/proxy/zai/api/...
#
# Cache (shared with the Aygea Claude statusline):
# ~/.cache/aygea-sl/quota.json { "pct": 23, "reset_iso": "...", "ts": ... }
#
# Env tunables:
# AYGEA_SL_SECRET_NAME vault secret name (default zai_api_key)
# AYGEA_SL_URL quota base URL (default https://api.z.ai)
# AYGEA_SL_NO_VAULT=1 skip SecretVault, use credential.json only
# AYGEA_SL_CRED_FILE credential.json path (default ~/.secretvault/credential.json)
# AYGEA_SL_QUOTA_CACHE cache path (default ~/.cache/aygea-sl/quota.json)
# AYGEA_SL_REFRESH_AFTER refresh when cache older (default 150 sec)
# AYGEA_SL_MAX_AGE hide when cache older (default 360 sec)
# AYGEA_SL_CURL_TIMEOUT curl --max-time (default 6)
# AYGEA_SL_ONLY_GLM=1 show only when session model name contains "glm"
# AYGEA_SL_MEM=1 prepend an 🧠 system-memory segment (Linux/macOS)
# NO_COLOR plain text output
#
# Modes: (none) statusline mode — always exit 0, print segment or nothing
# --refresh one foreground refresh, exit non-zero on failure
#
# Requires: jq, curl. Optional: secretvault, flock, setsid.
