An agent that +outputs this has satisfied the letter of the constraint but not the intent. + +Similarly, a partially-filled table: + +```md +| Name | Score | Notes | +|------|-------|-------| +| Alice | 95 | | +| | | | +| | | | +``` + +Has 3 rows by count, but only 1 row with any data. The 2 empty rows inflate the count +and mask the fact that the agent stopped filling after the first row. + +## Design + +### A: Drop Fully-Empty Rows on Normalization + +**Definition:** A "fully-empty row" is one where every cell has `state: 'skipped'` +(or equivalently, every cell value is empty/undefined after parsing). + +**Where to drop:** + +1. **At parse time** — in `parseMarkdownTable()` (`src/engine/table/parseTable.ts`), + after parsing all rows, filter out any row where every cell is `skipped`. This + means the parsed `TableValue` never contains fully-empty rows. + +2. **At patch apply time** — in the `set_table` and `append_table` handlers in + `apply.ts`, filter out fully-empty rows from the resulting row array. This handles + the case where an agent sends a patch with empty rows. + +**Helper function:** + +```typescript +/** + * Check if a table row is fully empty (all cells skipped/empty). + */ +function isRowFullyEmpty(row: TableRowResponse, columns: TableColumn[]): boolean { + return columns.every((col) => { + const cell = row[col.id]; + return !cell || cell.state === 'skipped' || cell.state === 'aborted' + || cell.value === undefined || cell.value === null || cell.value === ''; + }); +} +``` + +**Behavioral impact:** +- A template form with header + separator + 3 empty rows parses as a table with 0 rows +- Serialization of that table produces header + separator only (no empty data rows) +- `minRows` checks see the true count of substantive rows +- Progress computation sees the table as empty (not submitted) + +### B: Warn on Mostly-Empty Rows + +**Definition:** A "mostly-empty row" is one that has at least one answered cell, but +the majority of its cells (>= 50%) are empty/skipped. + +**Where to warn:** In `validateTableRow()` (`src/engine/validate.ts`), after +validating individual cells, check whether the row is mostly empty. If so, emit a +`warning`-severity issue. + +**Warning message:** + +``` +Row N of "TABLE_LABEL" has most cells empty (M of K filled). +Consider adding column constraints or making columns required. +``` + +**Severity:** `warning` (not `error`). This is advisory — a form author may +intentionally have sparse rows (e.g., an "optional notes" column). The warning helps +catch cases where an agent is producing low-quality output. + +**Threshold:** >= 50% of cells are empty in a row that has at least one filled cell. +This avoids warning on fully-empty rows (those are dropped by normalization) and on +rows that are mostly filled. + +### D: Strengthen minRows/maxRows Validation + +Since fully-empty rows are dropped during normalization (Part A), the `minRows` and +`maxRows` checks in `validateTableField()` will automatically count only substantive +rows. No additional filtering is needed in the validator itself — the normalization +layer guarantees that `rows.length` reflects substantive rows. + +**Changes needed in `validateTableField()`:** +- None for the `minRows`/`maxRows` logic itself (it already uses `rows.length`). +- The `isEmpty` check (`!value || rows.length === 0`) continues to work correctly + because normalization ensures that a table with only empty rows has `rows: []`. + +**Changes needed in `isFieldSubmitted()`** (`src/engine/summaries.ts:196-199`): +- No change needed — after normalization, `rows.length > 0` correctly means the table + has substantive data. + +**Documentation:** The spec and reference docs should clarify that `minRows` and +`maxRows` count only rows with at least one non-empty cell. + +## Components + +**Files to modify:** + +| File | Change | +| --- | --- | +| `src/engine/table/parseTable.ts` | Add `isRowFullyEmpty()` helper;
