name: Clone Tracker (14-day rolling)

# GitHub's clone API only retains 14 days. We run every 13 days so we always
# catch the full window with a 24h safety margin. The job appends a snapshot
# to `data/clone-data.rvf` (RuVector vector store) + `data/clone-data.ledger.json`
# (chronological JSON), regenerates `data/clone-data.proof.json` with a fresh
# SHA-256 over the ledger, and commits the result back to main.
#
# Schedule: every 13 days at 06:17 UTC (off-peak; avoids the :00 mark to
# spread cron load).
#
# Why we own this rather than rely on a third-party traffic-tracker: GitHub's
# clone API requires push access, so we'd have to give a stranger our token.
# Running it ourselves keeps the data path inside the repo and signed.
