v0 state

limiter

limiter starts at 0.5 tokens/block (one every two blocks), capacity 5.

Allow

Allow consumes one token for the calling realm/user at the current block height and reports whether the request is permitted. Returns false (and consumes nothing) when the caller's bucket is empty.

SetConfig

SetConfig updates the shared rate (tokens per block) and burst (capacity). rate is clamped to >= 0, burst to >= 1.

Tokens

Tokens reports how many whole tokens \`addr\` has available at the current block height, without mutating any state.

ftoa

Render

Render shows the limiter config and a table of known callers with their current tokens and last-seen height. Path "/addr/\<address>" focuses one caller.
