[Proposal] SwarmScore V1 + V2 Canary — Open Standard for Agent Reputation Scoring

Hi everyone,

I'd like to propose two complementary specifications for the community group's consideration:

**SwarmScore V1** (draft-stone-swarmscore-v1-00)
A transparent, community-governed open standard for agent reputation scoring in open marketplaces. Two-pillar scoring: Technical Execution (Conduit browser verification) and Commercial Reliability (AP2 escrow transactions). Produces cryptographically signed Execution Passports that travel with agents across marketplaces.

Key features:
- Deterministic formula (publicly auditable)
- Volume-scaled scoring (prevents single-transaction luck)
- Escrow modifier integration (score directly reduces required escrow hold)
- Trust tiers: NONE / STANDARD / ELITE
- Advisory Board governance (RFC 2026-style update process)
- Appeals process and legal framework for operators

**SwarmScore V2 Canary** (draft-stone-swarmscore-v2-canary-00)
Extends V1 with a Safety pillar measured via covert canary prompt testing. Five formally-analyzed design decisions covering: mandatory testing thresholds, hybrid pattern+LLM classification, dedicated test session placement, prompt library rotation, and session isolation.

Both specs are:
- IETF Internet-Drafts (submitted March 2026)
- Dual-licensed Apache 2.0 / MIT
- Backwards-compatible with each other (V2 adds fields, doesn't change V1 scores)
- Built on top of AP2 (escrow) and Conduit (verification) — both previously proposed to this group

These directly address the gap where AP2 defines payment flows but not agent trustworthiness signals. SwarmScore provides the reputation layer that marketplaces need to make routing decisions, set escrow amounts, and filter agents.

Happy to present at a biweekly meeting if there's interest.
