I downloaded an updated skill package from Yavira. Read SKILL.md from the extracted folder, compare it with my current installation, and upgrade it while preserving any custom configuration unless the package docs explicitly say otherwise.

## Documentation

### SettlementWitness

Generate a signed delivery receipt in under 30 seconds.

### Run This Now

settlement_witness({
task_id: "quickstart-001",
spec: { value: 1 },
output: { value: 1 }
})

You should receive:

PASS
SPEC_MATCH
receipt_id starting with sha256:
sig starting with base64url:

Example (truncated):

{
"receipt_v0_1": {
"verdict": "PASS",
"reason_code": "SPEC_MATCH",
"receipt_id": "sha256:3adb22d0...",
"sig": "base64url:AbC..."
}
}

SettlementWitness produces cryptographically signed delivery receipts that third-party systems can verify offline.

### Common Failure Modes

If you see 422
Missing required field. Ensure task_id, spec, and output are present.

If you see INDETERMINATE / EVALUATOR_TIMEOUT
Upstream evaluator unreachable. This is still a valid signed receipt.

If you see FAIL / SPEC_MISMATCH
Your output does not match your spec. Compare structures.

### Safety Notes

Never send secrets in spec or output. Keep inputs deterministic.
