run_job.sh was overwriting the log on every cron fire, making it impossible to see run history. Switch to append mode, print a ── YYYY-MM-DD HH:MM:SS ── separator before each run, and trim to the last 1000 lines after each run to keep logs bounded.

# Varaverk job runner — wraps script execution with JSON status tracking.
|
|
# Called by /etc/cron.d/varaverk for every scheduled job.
|

#
|
|
# Usage: bash run_job.sh <job_id> <script_path> [flags...]
|
|
#
|
|
# Writes: /var/log/varaverk/<id>.json — status, timestamps, exit code, pid
|
|
# /var/log/varaverk/<id>.log — appended per run, trimmed to LOG_MAX_LINES
|
|
#
|
|
# Status values: running → ok (exit 0) | warn (exit 1) | error (exit 2+)
