Science Ladder CLI 0.3.0

Download the CLI for macOS or Linux on ARM64 or AMD64. No Go compiler is required. The installer at https://scienceladder.org/install.sh selects the binary and verifies its release checksum.

• sl clone, sl doctor, sl setup and sl run provide a pinned challenge workspace and native local checks.
• sl submit uses workspace context, repeats final validation and requests admission only for eligible frontier claims.
• Existing explicit claim, submission, receipt and export commands remain supported.
• Creator recipes live in science-ladder-local.json in the pinned challenge source.

The challenge page now shows ranked submissions and the current leader or reference directly. Chart axes use compact labels with exact values available for inspection, and milestone labels no longer overlap.

Workflow and recipe documentation. First-party code is MIT licensed. Source identity is included in source.json and sl version; SHA256SUMS covers all four binaries.
