Context

This skill implements FPF Pattern G.6 (EvidenceGraph). In the experiment (Conditions C1/C2), files act as the carrier. Evidence must be immutable and addressable.

Instructions

Write the provided content to the telemetry/ or artifacts/ directory.

1. Naming Convention (Immutability)

You must generate a filename that guarantees uniqueness/immutability.

• Preferred: timestamp_sha256.json (e.g., 20240110-1200_a1b2c3...json)
• Alternate: uuid.json

2. Formats

• Content MUST be valid JSON.
• If content is not JSON, wrap it: {"content_type": "text/plain", "body": "..."}.

3. Output

Return the absolute path of the persisted artifact.
