- Editor is a full screen, not a bottom sheet (§13.2). Amount input accepts digits, one decimal separator (`,` or `.`), at most two decimals, no sign, converted to öre by string parsing, never floating point (§9.6).
- Defaults: account = last used on this phone if active else oldest active; category = last used in that account if active else `other`; split mode `default`; payer = current user; date = today in the phone's zone (AC-8.3, AC-8.4, AC-8.6). Defaults come from `ExpenseEditorOptions`.
- Split modes `default` ("Account default 60/40"), `ratio`, `exact` (type one share, the other is amount minus it, read-only; a share larger than the amount blocks saving inline), `full` (one bearer); changing account in `default` re-copies the ratio; live preview from `ExpenseRepository.preview` (AC-8.5, AC-8.7, AC-8.8, §13.3 S-7).
- Validation errors come back as `SaveResult.Invalid` with §14.5.3 tokens or `required`; deleting asks for confirmation (AC-8.9).
- Validation errors come back as `SaveResult.Invalid` with §14.5.3 tokens, `required`, or `validation_failed` for a §9.6 limit without a domain token (lengths, dates) (§9.6, §14.2.4); deleting asks for confirmation (AC-8.9).
- Detail shows amount, description, category, account, date, payer, shares and mode, notes, "Recurring: <template>" when generated, and the timeline: newest last, one line per entry, field names in the UI language, ids resolved, pending line "Your change is waiting to sync"; a deleted state when opened from a deletion notification (AC-8.11, AC-12.4, AC-12.5, §13.3 S-8).
