- Add resolve_constraints_in_content() to handle ${constraint.path} patterns
- Integrate into all form loading functions (load_from_file, load_fragment_form, etc)
- Support nested path navigation (e.g., constraints.tracker.udp.max_items)
- Add test_constraint_interpolation() test
fix(nickel-roundtrip): apply constraint interpolation in roundtrip workflow
- Fix execute_form() to use load_from_file() instead of parse_toml()
- Ensures constraints are resolved in roundtrip mode
docs(examples): add constraint interpolation example
- Create examples/05-fragments/constraints.toml
- Update examples/05-fragments/array-trackers.toml to use ${constraint.*}
- Document constraint workflow in examples/05-fragments/README.md
Benefits:
- Single source of truth for validation limits
- Forms auto-resolve constraints at load time
- All layers (Forms, Nickel, Templates) sync automatically
- Fix has_unique flag reading from field definition (was scanning fragment fields)
- Implement duplicate validation in CLI and TUI backends
- Add item counter update in Web backend after add/delete operations
- Refactor Web JavaScript: remove global constants, use closure-based state per group
- Store repeating group config in data-* attributes instead of global variables
- Update documentation and examples with unique = true attribute
- All backends now enforce unique items validation consistently
Add contract parsing, i18n extraction, template rendering, and roundtrip
support for Nickel. Update backends and form parser for integration.
Add testing and build infrastructure.
