✓ Chain verified — 1 indexing event, hash-chained and tamper-evident. Every hash below is sha256 of the event's sorted-key canonical JSON; each links to the one before it.

Every indexing proves two things — authorization (were agents welcome? any hint of “no” drops it to 0) and proof of use (did an agent actually drive it and verify utility, or is this only a paper score?) — plus the agent-native review. All three are recorded in each event below.
