Batch 1 (quick-fixes):
- Field.Copy attribute + IsCopyable() method for copy control
- Constraints now run in Write() (was only Create — bug fix)
- Readonly fields silently skipped in Write()
- active_test: auto-filter archived records in Search()
Batch 2 (Related field write-back):
- preprocessRelatedWrites() follows FK chain and writes to target model
- Enables Settings page to edit company name/address/etc.
- Loop protection via _write_related_depth context counter
Batch 3 (_inherits delegation):
- SetupAllInherits() generates Related fields from parent models
- preprocessInheritsCreate() auto-creates parent records on Create
- Declared on res.users, res.company, product.product
- Called in LoadModules before compute setup
Batch 4 (Copy method):
- Recordset.Copy(defaults) with blacklist, IsCopyable check
- M2M re-linking, rec_name "(copy)" suffix
- Replaces simplified copy case in server dispatch
Batch 5 (Onchange compute):
- RunOnchangeComputes() triggers dependent computes on field change
- Virtual record (ID=-1) with client values in cache
- Integrated into onchange RPC handler
