…ket clients From konstellation PR #14: - contracts.md: cosmos/evm v0.7.3 lists a "vesting" precompile at 0x…0803 but ships no implementation; PR #14 drops it from ActiveStaticPrecompiles, so the active set is ten (0x100, 0x400, 0x800–0x802, 0x804–0x807, 0x900). The table now shows 0x…0803 as unassigned instead of "vesting". - rpc-endpoints.md: new "WebSocket from a browser" section — [json-rpc] ws-origins holds browser Origin hosts (no scheme, no port; hostname compare), default ["127.0.0.1", "localhost"]; matching Origin → 101, non-matching → 403, absent Origin always admitted; note that binaries before PR #14 flattened the array and returned 403 for every browser Origin. - troubleshooting.md: matching entry for the 403 symptom, with the old-binary case and the --json-rpc.ws-origins command-line workaround. npm run build: green.
