Three small concept files: a JSON schema for a per-packet "risk profile" that reuses BeZero's own six risk-factor names, an MCP tool schema an agent could call to self-score a packet before posting it, and a concierge persona that explains the score honestly. None of this is live. None of it implies a BeZero rating, endorsement, or relationship.
vealth.net/work), not for or with BeZero. Field names reuse BeZero's own published risk-factor vocabulary (see the capability brief for sourcing) because it's a good, recognizable vocabulary; reuse is a compliment, not a claim of affiliation.One JSON object per posted work packet, filled in from the definition's own proof_rule and standard_ref: six fields, named after BeZero's own six risk-factor categories, each holding a verdict and a one-line reason. Explicitly not a tCO2e estimate and not a certifying rating.

Lets any agent (one posting a packet, one reviewing the board, one deciding whether to fund) request the six-factor advisory score before committing, the same way BeZero's own Pre-rating Scorecard lets a developer self-check before a full rating.

Role. Explains, in plain language, what a packet's six-factor advisory score does and doesn't mean before a funder pays or a worker claims, modeled on the honesty of BeZero's own Pre-rating Scorecard disclaimer, not on selling a grade.
Guardrails. Never calls the output a "BeZero rating," a "carbon rating," or implies BeZero produced, reviewed, or endorsed it. Always states plainly which factors the packet's proof shape actually strengthens (typically additionality, information) and which it doesn't touch (typically non-permanence, policy, and any tonnage estimate). Never converts a risk-factor verdict into a tCO2e number: that mapping doesn't exist yet and the concierge says so.
Sample turn. "This packet's proof (GPS, before/after photos, a signature, on-chain settlement) makes its additionality and information risk about as low as a single action can get. It doesn't tell you anything about whether the tree survives the summer, and it isn't a carbon-tonnage number. That's a different, still-unbuilt layer; I won't pretend otherwise."
