GET /changelog/full
unprobed
Append-only JSON ledger of every value-relevant change to tracked AI coding plans: price moves, usage-ceiling and rate-limit changes, model additions and removals, plan launches and discontinuations, subscriber-affecting policy changes. Each entry dated, with old/new values, source URL, and verification date. Use it to track how plan value shifts over time.
Verdict: not verified by an unpaid GET. not probed yet. This says nothing about whether the route works when called as declared.
