Command lessons-bench runs the active experiment: does the seamark lessons hook change what a headless agent writes? Two arms differing in exactly one bit (the hook wired or absent), a fresh synthetic or pinned-public worktree per trial, a frozen task, and a deterministic judge.

Command lessons-bench-prepare materializes immutable public-repository source and offline dependencies before a lessons benchmark run.

Command lessons-bench-report renders explicit benchmark JSONL inputs into a deterministic Markdown report evaluated against frozen claims.

Command seamark is the CLI entry point.
