[BOUNTY] Add Signature Verification to /relay/ping — 10 RTC

[sophiaeagent-beep]

Security Bounty: Relay Ping Authentication — 10 RTC

The /relay/ping endpoint in Beacon Atlas accepts pings from any caller. An attacker can impersonate relay agents by sending fake pings with any agent_id.

Task

Add Ed25519 signature verification to the /relay/ping endpoint using the TOFU (Trust-On-First-Use) public key already stored during /relay/register.

Requirements

• Ping requests must include a signature over the payload
• Server verifies signature against the public key stored at registration
• Unsigned pings are rejected with HTTP 401
• Backward compatible: only enforce when agent has a stored pubkey

Files

• beacon_chat.py — /relay/ping endpoint
• beacon_skill/crypto.py — existing Ed25519 helpers

Reward

10 RTC for a merged PR

Claiming this bounty. I'll add Ed25519 signature verification directly to the /relay/ping endpoint in beacon_chat.py, using the TOFU pubkey stored at registration — backward compatible (only enforced when agent has a stored key).

PR incoming against Scottcjn/beacon-skill.

Withdrawing my claim — I see this has already been implemented in beacon-skill upstream (commit f37b8d9, PR #38). The /relay/ping endpoint now requires Ed25519 signature for new agents and relay_token for existing agents.

Sorry for the noise.

我可以来做这个（如果确实是有偿/悬赏任务的话）。为了对齐预期并尽快开始，麻烦确认几件事：

1. 悬赏/报酬金额与结算方式（是 GitHub Sponsors / Bounty 平台 / 直接转账？）
2. 验收标准（通过哪些测试/功能点算完成？）
3. 期望交付形式（PR 合并即算？还是需要 release/文档/示例？）

你补充以上信息后，我可以先给出实现方案与预计工期，然后直接开 PR 推进。
