## How to Continue

1. **Reference the mapping**: See `constraint_interpolation_guide.md` for complete field → constraint mappings

2. **For fragments with existing constraints** (e.g., `security-section.toml`):
   ```bash
   # Update fields using the pattern from completed fragments
   # Example: jwt_token_expiration → control_center.jwt.token_expiration
   ```

3. **For fragments without existing constraints** (e.g., `performance-section.toml`):
   - Use reasonable domain-based ranges
   - Document your choice in the help text
   - Examples:
     - Timeouts: 1s-1hr range (1000-3600000 ms)
     - Thread counts: 1-32 range
     - Memory: 64MB-256GB range (use deployment modes)
     - Ports: use `common.server.port` (1024-65535)

## Testing

After updating a fragment:

```toml
# 1. Verify fragment syntax
cd provisioning/.typedialog/provisioning/platform/forms/fragments
grep -n 'min = \|max = ' <fragment-name>.toml | head -20

# 2. Validate constraints exist
cd ../..
grep -r "$(constraint path)" constraints/constraints.toml

# 3. Test form rendering
typedialog-cli validate forms/<service>-form.toml
```

## Notes

### Pattern Applied
All numeric fields now follow this structure:
```toml
[[elements]]
default = 10
help = "Field description (range: ${constraint.path.min}-${constraint.path.max})"
min = "${constraint.path.min}"
max = "${constraint.path.max}"
name = "field_name"
nickel_path = ["path", "to", "nickel"]
prompt = "Field Label"
type = "number"
```

### Benefits Realized
- ✅ Single source of truth in `constraints.toml`
- ✅ Help text shows actual valid ranges to users
- ✅ TypeDialog validates input against constraints
- ✅ Jinja2 templates receive validated values
- ✅ Easy to update limits globally (all forms auto-update)

## Completion Summary

**Final Status**: 33/33 fragments (100%) ✅ COMPLETE

**Work Completed Today**:
- ✅ orchestrator/performance-section.toml (5 fields with max bounds)
- ✅ orchestrator/storage-section.toml (4 fields with max bounds)
- ✅ control-center/policy-section.toml (3 fields with max bounds)
- ✅ control-center/users-section.toml (3 fields with max bounds)
- ✅ Fragments with no numeric fields (rbac, mode-selection, workspace) verified as complete

**Total Progress This Session**:
- Started: 12/33 (36%)
- Ended: 33/33 (100%)
- +21 fragments updated
- +50+ numeric fields with constraint bounds added

### Next Phase: Phase 8 - Nushell Scripts
Ready to proceed with implementation:
- Interactive configuration wizard (configure.nu)
- Config generation from Nickel → TOML (generate-configs.nu)
- Validation and roundtrip workflows
- Template rendering (Docker Compose, Kubernetes)

## Files

- `constraints/constraints.toml` - Source of truth for all validation limits
- `constraint_interpolation_guide.md` - Complete mapping and best practices
- `constraint_update_status.md` - This file (progress tracking)

**To contribute**: Pick any unchecked fragment above and follow the pattern in `constraint_interpolation_guide.md`. Each constraint update takes ~5 minutes per fragment.
