description	Implement and maintain currency localization plus explicit property surface model for Anclora Nexus. Use when touching price formatting, currency selector behavior, area fields (useful/built/plot), and origin-based editability contracts for properties/contacts.

Currency & Surface Localization

Workflow

1. Read:

• sdd/features/currency-surface-localization/currency-surface-localization-INDEX.md
• sdd/features/currency-surface-localization/currency-surface-localization-spec-v1.md
• sdd/features/currency-surface-localization/currency-surface-localization-spec-migration.md
• .agent/rules/feature-currency-surface-localization.md

2. Implement in order:

• DB migration and backfill
• Backend contract and validation
• Frontend formatting/unit UX
• QA and release gate

3. Preserve compatibility:

• keep legacy surface_m2 operational during v1 rollout.

Minimal v1 contract

• Currency toggle independent from language.
• Formatters for EUR/GBP/USD/DEM/RUB.
• Surface trio: useful_area_m2, built_area_m2, plot_area_m2.
• Origin-based editability policy enforced.

Stop rules

• Do not mix unrelated feature scopes.
• 1 prompt = 1 commit.
• Agent must stop after its assigned block.
