What problem does it solve? Web sources cited in investigations disappear, change, or sit behind paywalls, leaving findings unverifiable and legally indefensible. This Skill preserves evidence at the moment of discovery with tamper-evident snapshots and provenance records. ## Core Features & Use Cases - First-party Tier-0 snapshots: Capture pages as content-addressed MHTML archives plus full-page screenshots and response headers via the dev-browser CLI, with SHA-256 filenames for deduplication and integrity. - Third-party archiving: Submit URLs to the Wayback Machine and Archive.today for independent verifiability, including CDX API lookups for existing snapshots and dead-page recovery. - Chain of custody: Embed a provenance header in every archived file and record snapshots in evidence-bundle.json so hashes flow into a C2PA-signed provenance manifest. - Use Case: An investigator finds a key article supporting a claim. The Skill validates the URL, captures an MHTML snapshot and screenshot, submits the page to Wayback, and writes an archived copy with a chain-of-custody block before the URL is ever cited in findings.json. ## Quick Start Archive this URL before I cite it in my investigation: https://example.com/article.
