Fixed Assets

Revalue a fixed asset (IFRS IAS 16 mark-to-market write-up)

Write-up only. Increases the asset’s cost_basis to a new net book value, posting DR Fixed Asset / CR Revaluation Surplus (equity). Falls back to retained_earnings when no revaluation_surplus account is seeded. The new_book_value MUST exceed the current net book value; for write-downs use POST /impair instead. Two elections:

ifrs (default): standard IAS 16 revaluation model. Credit goes to revaluation_surplus (equity OCI).
us_gaap: rarely permitted under ASC 360. Use only when your accounting policy explicitly allows US GAAP write-ups; otherwise the impairment-recovery model in POST /recover_impairment is the conventional path.

Rule 21 enforces GL postability + balance inside postJournalEntry. Rule 23: this is the ONLY function besides createFixedAsset that writes fixed_assets.cost_basis. Idempotent when Idempotency-Key is supplied.
