+# Evidence Quick Reference — Wizards
+*One-page summary of the evidence law for draft artifacts.*
+
+---
+
+## The Law (3 rules)
+
+1. **Prepared ≠ Observed.** A plan, a stub, or a "will do" is not a build, a test, or a result.
+2. **Executor ≠ Witness.** "The executor said done" is not "a test passed."
+3. **Evidence on every claim.** Every claim must attach a source, a timestamp, and an owner.
+
+---
+
+## Claim Anatomy
+
+```
+[CLAIM] <one sentence, no vague language>
+[SOURCE] <file path | URL | tool call | person + timestamp>
+[MEASURED] <command / observation> | [CLAIMED] <label + falsifier>
+[OWNER] <who observed, not who requested>
+```
+
+---
+
+## Verdict Block (required on every artifact)
+
+```
+VERDICT: <pass | fail | partial> — <one-line evidence summary>
+CHECK: <single bare shell command whose exit code IS the verdict>
+```
+
+- No `|| true`, no `; echo …`, no hard-coded success.
+- The command must inspect the artifact, not print a constant.
+
+---
+
+## Common Failures
+
+| Failure | Fix |
+|---|---|
+| "Seems likely" | Replace with measured value or label `CLAIMED` + falsifier |
+| No source | Add `[SOURCE]` with exact path, URL, or tool call |
+| No timestamp | Add ISO-8601 UTC observation time |
+| Owner is the requester | Owner must be the witness who observed the evidence |
+| Tautological CHECK | Make the command inspect the artifact (e.g. `grep -c 'VERDICT:' file`) |
+| Stale claim (>24 h) | Flag and re-measure, or note the staleness |
+
+---
+
+## Minimal Checklist
+
+- [ ] Every claim has `[SOURCE]`.
+- [ ] Every measured result has the reproduction command.
+- [ ] Every claimed-only item is labeled `CLAIMED` with a falsifier.
+- [ ] Timestamps are ISO-8601 UTC.
+- [ ] Owner is the observer, not the requester.
+- [ ] `VERDICT:` line is present and evidence-backed.
+- [ ] `CHECK:` is a single bare command; exit code matches verdict.
