Pq Key Binding Ots

The raw OpenTimestamps proof (.ots) for the PQ key binding's event_id -- a real gap found 2026-07-30 (flagged in trustless-ai group by an independent reviewer, "M"): the binding's ots_anchor block pointed at a local file path that had no public route, unlike every /ledger entry's own /ledger/{entry}/ots (which does). Same pattern as that route: feed this to ots verify -d <event_id> <event_id>.ots to confirm the Bitcoin-PoW anchor against any explorer, no trust in us.
