Use reasonable domain-based ranges\n   - Document your choice in the help text\n   - Examples:\n     - Timeouts: 1s-1hr range (1000-3600000 ms)\n     - Thread counts: 1-32 range\n     - Memory: 64MB-256GB range (use deployment modes)\n     - Ports: use `common.server.port` (1024-65535)\n\n## Testing\n\nAfter updating a fragment:\n\n```\n# 1. Verify fragment syntax\ncd provisioning/.typedialog/provisioning/platform/forms/fragments\ngrep -n 'min = \|max = ' <fragment-name>.toml | head -20\n\n# 2. Validate constraints exist\ncd ../..\ngrep -r "$(constraint path)" constraints/constraints.toml\n\n# 3. Test form rendering\ntypedialog-cli validate forms/<service>-form.toml\n```\n\n## Notes\n\n### Pattern Applied\nAll numeric fields now follow this structure:\n```\n[[elements]]\ndefault = 10\nhelp = "Field description (range: ${constraint.path.min}-${constraint.path.max})"\nmin = "${constraint.path.min}"\nmax = "${constraint.path.max}"\nname = "field_name"\nnickel_path = ["path", "to", "nickel"]\nprompt = "Field Label"\ntype = "number"\n```\n\n### Benefits Realized\n- ✅ Single source of truth in `constraints.toml`\n- ✅ Help text shows actual valid ranges to users\n- ✅ TypeDialog validates input against constraints\n- ✅ Jinja2 templates receive validated values\n- ✅ Easy to update limits globally (all forms auto-update)\n\n## Completion Summary\n\n**Final Status**: 33/33 fragments (100%) ✅ COMPLETE\n\n**Work Completed Today**:\n- ✅ orchestrator/performance-section.toml (5 fields with max bounds)\n- ✅ orchestrator/storage-section.toml (4 fields with max bounds)\n- ✅ control-center/policy-section.toml (3 fields with max bounds)\n- ✅ control-center/users-section.toml (3 fields with max bounds)\n- ✅ Fragments with no numeric fields (rbac, mode-selection, workspace) verified as complete\n\n**Total Progress This Session**:\n- Started: 12/33 (36%)\n- Ended: 33/33 (100%)\n- +21 fragments updated\n- +50+ numeric fields with constraint bounds added\n\n### Next Phase: Phase 8 - Nushell Scripts\nReady to proceed with implementation:\n- Interactive configuration wizard (configure.nu)\n- Config generation from Nickel → TOML (generate-configs.nu)\n- Validation and roundtrip workflows\n- Template rendering (Docker Compose, Kubernetes)\n\n## Files\n\n- `constraints/constraints.toml` - Source of truth for all validation limits\n- `constraint_interpolation_guide.md` - Complete mapping and best practices\n- `constraint_update_status.md` - This file (progress tracking)\n\n---\n\n**To contribute**: Pick any unchecked fragment above and follow the pattern in `constraint_interpolation_guide.md`. Each constraint update takes ~5 minutes per fragment.
