💡 Inter-Market Vendor Reputation & Reference Network

[github-actions[bot]]

Summary

Enable market managers to leave positive attestations for vendors who participate in their markets, creating a cross-market reputation layer. When a vendor applies to a new market, the receiving manager can view attestations from other markets — like a professional reference network for the farmers market ecosystem.

Market Signal

No competitor in the space (Seen Markets, Marketspread, ManageMyMarket, MarketWurks) offers cross-market vendor reputation infrastructure. The farmers market ecosystem relies entirely on word-of-mouth, social media presence, and informal phone calls for vendor vetting. As the number of multi-market vendors grows — a trend confirmed by the multi-market architecture in the Markets PRD and by industry reports showing vendors increasingly selling at 2-4 markets per week — structured trust signals become critical infrastructure. Seen Markets has DMs between hosts and vendors but no formalized reputation or reference system.

User Signal

Discussion #480 (Manager Vendor Recruitment & Outreach Pipeline) demonstrates demand for vendor recruitment tooling but lacks the trust-verification layer that makes recruitment decisions confident. Discussion #431 (Vendor Compliance & Market Rules Acknowledgment) covers rules compliance but not experiential reputation — knowing a vendor signed the rules is different from knowing they were a reliable, professional participant. Discussion #395 (Vendor Attendance Track Record) provides quantitative attendance reliability data but not qualitative manager assessments like "great communicator" or "consistently high quality products."

Technical Opportunity

The multi-market data model (FR5, FR6, FR7) already supports vendors associated with multiple markets and managers with market-scoped permissions — the data relationships for cross-market attestations are already in place. Attestations are append-only records, aligning naturally with the audit architecture (NFR12). The vendor profile (FR11) is the natural display surface. The GraphQL schema can extend the vendor type with an attestations connection scoped to manager visibility during application review (FR10, FR10a). The manager-on-behalf action attribution pattern (FR20a, FR44) provides the model for tracking which manager left which attestation.

Assessment

Dimension	Score	Rationale
Feasibility	med	New data model (attestation records) but straightforward CRUD. No external integrations needed. Builds on existing vendor-market associations.
Impact	high	Reduces vendor vetting friction for managers, strengthens trust in the multi-market ecosystem, and creates a defensible network effect (vendor reputation data is locked in the platform).
Urgency	med	No competitor has this. Multi-market vendor growth creates increasing demand for structured vetting. First-mover advantage on reputation data creates a compounding moat.

Adversarial Review

Strongest objection: Farmers market communities are tight-knit. A formalized reputation system could create social friction and legal liability concerns if managers feel pressured to leave negative references or fear defamation claims from vendors they decline to endorse.

Rebuttal: Design as a positive-only attestation system: managers can attest "I would welcome this vendor back" with optional notes, but cannot leave negative reviews. Absence of attestation is itself a signal without the toxicity of negative feedback. Combined with the quantitative attendance track record (Discussion #395), managers get both social proof and objective reliability data without anyone needing to say something negative. This mirrors how professional references work in other domains — you only list people who will speak well of you. The positive-only constraint also eliminates defamation liability.

Suggested Next Step

Design the attestation data model (attesting manager, vendor, market context, date, optional structured note). Mock up the attestation display on the vendor application review screen (FR10). Survey 5 market managers about their current vendor vetting process, what information they wish they had, and whether they would provide positive attestations for good vendors.
