# DoNotAct Evidence Model

DoNotAct v1.1 is a diagnostics API for public prediction-market evidence.

## Evidence Chain

1. Public venue fetch
2. Normalized market metadata
3. Normalized public orderbook, when available
4. Deterministic diagnostic checks
5. Verdict assembly
6. Structured `no_trade_reasons`
7. Structured `what_would_change_this`
8. Diagnostic event ledger

## What Evidence Can Mean

Evidence can show which public endpoint was queried, whether public market metadata was available, whether public orderbook data was fresh enough, whether prices aligned to venue rules, whether resolution text contained ambiguity patterns, and why the API returned `READY`, `DO_NOT_ACT`, or `INSUFFICIENT_EVIDENCE`.

Evidence does not show returns, settlement certainty, complete market coverage, a probability estimate, a trade recommendation, or a stake instruction.

## Agent Rule

Agents must preserve verdicts, reason classes, evidence gaps, caveats, and `not_advice=true`. Missing evidence is not favorable evidence.
