### FT-01: universal help lists non-help commands

- **Given:** genfile binary is available
- **When:** `.` or `.help` is invoked
- **Then:** Exit code 0; output lists `.archive.new`, `.file.add`, and other non-help commands; no `.archive.new.help` entries in the list
- **Tests:** none — see task/001_fill_test_surface_gaps.md

### FT-02: per-command help shows parameters and examples

- **Given:** genfile binary is available
- **When:** `.archive.new.help` is invoked
- **Then:** Exit code 0; output describes `.archive.new`, lists its parameters with kinds/defaults, and shows usage examples
- **Tests:** none — see task/001_fill_test_surface_gaps.md

### FT-03: help commands filtered from normal listings

- **Given:** genfile binary is available
- **When:** `.` is invoked (universal help)
- **Then:** Output does NOT include `.archive.new.help` or any `*.help` entries
- **Tests:** none — see task/001_fill_test_surface_gaps.md

### FT-04: .help alias behaves identically to .

- **Given:** genfile binary is available
- **When:** `.help` is invoked
- **Then:** Exit code 0; output is equivalent to `.` invocation
- **Tests:** none — see task/001_fill_test_surface_gaps.md
