Offer Claims Registry

Use when the user asks to "register this claim", "log our current offers", or "where is the proof for this figure"; curates the canonical claims ledger and live-offers table under memory/claims/ — exact claim text, evidence provenance, approved wording, claim-level disclaimers, and offer terms — and resolves "[needs source]" flags from ad and content drafts. Not for scoring O1/O2 vetoes or issuing SHIP/FIX/BLOCK verdicts — use ad-account-auditor; not for gating creator content — use content-reviewer. 广告声明台账/优惠信息登记/证据溯源
