Passed in 47s. Attempt 2. Run 20260904T112413Z-gpt-5-6-sol-csv-reconcile-2.

Task

Find the payout mismatches

Compare stripe_payouts.csv with bank_deposits.csv.

Each Stripe row names the expected bank deposit after its fee. A matching bank deposit has the same payout id, the expected amount, and a date no more than two calendar days after the payout. Find these problems: a missing deposit, a deposit short by the Stripe fee, a duplicate deposit, a deposit more than two days late, and a bank deposit with no Stripe payout.

Write mismatches.csv with exactly this header:

id,kind,amount

Use the payout id for payout-side problems and the bank deposit id for a bank-only problem. amount should be the missing or extra amount for missing, short, duplicate, and bank-only rows; for a late deposit, use the deposit amount. Use a short plain label in kind.

---

# Spreadsheets skill
Read entirely for spreadsheet creation, editing, analysis, or visualization.

## Decision Boundary
- Google Sheets targeted outputs also require `routing/google_sheets.md`. Otherwise, author local files with artifact tool.

## Important Instructions
- For new workbooks or authorized redesigns, plan the simplest correct workbook that meets the task, audience, actual data and domain. If formulas become hard to read, first reconsider whether the workbook’s structure, layout, or logic is overcomplicated before simplifying individual formulas. Remove unnecessary or duplicated logic while preserving calculation correctness, required business relationships, and financial reconciliation
- Instruction precedence for workbook content, layout, and formatting is: user request > reference/template > domain defaults/conventions > general defaults.

## Tools + Contract Requirements
- Author spreadsheet with `@oai/artifact-tool` JS and only `load_workspace_dependencies` executables/dependencies, never repo-local deps. If unavailable, check `~/.cache/codex-runtimes/codex-primary-runtime/dependencies/`. Never modify dependency directories.
- In a writable, conversation-specific or tmp directory, create a `node_modules` symlink or Windows junction to the loader `node_modules`.
- Prefer to patch/rerun one `.mjs` builder. No heredocs or duplicate builders.
- Use the provided API reference. Do not inspect package internals or prototypes. If blocked, run at most one targeted `workbook.help("<api_or_feature>")` query.
- No `openpyxl`, `xlsxwriter`, or `pandas.ExcelWriter` authoring unless asked, or  `@oai/artifact-tool` is unavailable.
- Analyze with JS/formulas, else bundled Python (libraries) and JSON/CSV intermediates; other libraries only for missing capabilities.
- Use `update_plan` for complex work.
- In your final response, omit builders, previews, or other support files unless requested.
- Immediately before the first create/edit authoring command, run `mark_artifact_operation_started.mjs` successfully exactly once using the command below. Do not run it for read-only work. For edits, replace `create` with `edit`; adjust the expected count and output format to match the requested outputs.
  ` ` `bash
  node container_tools/mark_artifact_operation_started.mjs --operation-kind create --expected-output-count 1 --output-format xlsx
  ` ` `

## Writing Quality and Authored Content
For newly authored content, including additions during edits:

- Write for intended audience. Never include internal file paths, authoring commentary, planning notes, or requester instructions in the artifact unless explicitly requested. Do not repeat audience or style directives such as “executive-friendly” in headings, content, or comments.

- Use concise, literal subject titles and labels. Put company, timeframe and source context in subtitles or nearby notes.
  - Good: `Weekly metrics`. Bad: `Follow the weekly trends`
  - Good: `Monthly results`. Bad: `Decision-ready monthly impact analysis`
  - Good: `Income and household assumptions`. Bad: `Same paycheck. Different purchasing power.`

- Prefer direct, specific human wording. Avoid slogans, buzzwords, invented terminology, vague framing and formulaic claims.
  - Good: `Contributions decreased`. Bad: `Contributions waned`
  - Good: `Permanent drop in commuting`. Bad: `Structurally lower commute base`
  - Good: `Revenue metrics`. Bad: `Strategic Value Drivers`

- Avoid AI-like sentence constructions when simpler wording is clearer:
  - Semicolons: `Travel demand and employment from Jan to Feb. Persistent behavior shifts are shaping recovery.` not `Travel demand and employment fell from Jan to Feb; persistent behavior shifts are shaping the path back.`
  - Passive voice: `The team approved the proposal.` not `The proposal was approved by the team.`
  - Contrast slogans like `It’s not X, it’s Y`: `Humidity exposure over time` not `Humidity is an exposure trajectory, not a setpoint.`

- Keep wording factual, parseable and supported by the workbook.
  - Good: `Transit use is at 79%, matching pre-pandemic levels`
  - Bad: `79% Transit use back to pre-pandemic`

- Avoid AI-style decoration in titles and labels: bullets, icons, emoji, pipe-delimited titles, decorative arrows, or generic suffixes such as `review`, `impact`, `analysis`, or `dashboard`.
  - Good: `$ in USD`
  - Bad: `$ in USD • monthly • forecast`

- For checks and logic, be specific:
  - Bad: `Signal integrity: BLOCKED`. Good: `Missing input: forecast rate` (a specific functional warning)

- Do not include motivational wording, self-assessment, repeated setup. Do not add decorative badges, confidence ratings, status tags or PASS/WARN/BLOCKED banners.
  - Bad: `This workbook is source-backed and ready for review`. Omit the self-assessment, and keep needed sources and limitations besides analysis if actually useful.

User requests and preferences always take priority. For edits, follow existing writing style in the workbook.


## Workflows
Required:
- `workflows/edit_workflows.md` for existing files/follow-ups.
- `workflows/create_workflows.md` for new files

## Resources
Read the following BEFORE starting the task:

Required:
- `artifact_tool_docs/API_QUICK_START.md` for `artifact_tool` JS API documentation. Read entirely.
- `style_guidelines.md` for formatting.

As applicable:
- `references/template-elicitation.md`: if user has not provided a template, reference, or visual direction.
- `references/image-references.md`: if a reference image or screenshot is provided.
- `references/read_only_qna.md`: for Q&/audits
- `features/charts.md`: for creating or editing charts.

## Domain Requirements
Read only relevant guidance:
- Finance and investment banking: `domain_guidance/financial_models.md`
- Corporate finance and FP&A: `domain_guidance/corporate_finance_fpa.md`
- Healthcare: `domain_guidance/healthcare.md`
- Marketing and advertising: `domain_guidance/marketing_advertising.md`
- Scientific research: `domain_guidance/scientific_research.md`

## Create and Edits
For any task that requires modifying or creating a workbook:

### Formula Correctness
Apply to newly added or edited formulas, alongside the relevant create/edit workflow.

- Keep raw data, assumptions, editable mappings, scoring rules and thresholds in labeled inputs/tables. Mathematical, index and control constants may remain in formulas.
- Keep calculated outputs formula-driven so they update with inputs. Use consistent patterns across comparable rows and projection periods, preserving intentional differences. Reuse shared results; keep independent reconciliation checks independent.
- Use the simplest correct, human-readable formula. Formulas must be **easily auditable**. Do not perform complex calculations in a single cell when possible. Instead, use helper cells for intermediate values, direct references, arithmetic, aggregates and lookups like INDEX/MATCH/XLOOKUP, SUMIFS etc. Use supported LET, IF or arrays only when they improve clarity. Users should be able to trace the model from inputs to outputs easily.
- Reuse results or shared checks only when inputs, periods, units, rounding and overrides match; gate only affected outputs. Add helpers for meaningful repeated work, not trivial expressions; narrow edits do not authorize new helper ranges. Compute shared intermediate calculations once in labeled helper cells.
- Make formulas copy/fill-safe: reference destination headers/IDs, anchor only fixed sources, and use keyed lookups when layouts differ. Derive period filters/labels from destination keys;
- Quote cross-sheet names, e.g. ='Sheet Name'!A1.
- Keep workbook validation useful and proportional to realistic input risks. Reuse checks and separate them from calculations. Block outputs only when invalid inputs would make them misleading; do not invent business restrictions to validate inputs.
- Handle expected missing/invalid inputs explicitly; avoid blanket IFERROR wrappers or plausible-zero substitutes for unexpected errors. When simplifying, preserve calculation meaning, intended blank/error behavior, one-offs and overrides. Remove redundant guard layers while preserving checks that expose invalid source data.
- Scale verification to complexity and risk: check references/results for simple formulas; test representative inputs, copies and affected outputs for complex or consequential calculations. Keep authoring-only tests out of the workbook.
- For source-backed analyses, spot-check representative outputs and reconcile key totals with source definitions.
- Use numeric tolerances consistent with required calculation precision; compare identifiers, integer counts and categories exactly.

### Data Formatting Rules
- Store numbers, percentages, currency, and dates as typed spreadsheet values, not preformatted strings. Use text only for true identifiers such as ZIP codes, account IDs, SKUs, or labels.
- Use Excel-invariant number/date format codes, not locale-specific display strings. Generic examples include `#,##0`, `#,##0.0`, `0.0%`, `0.00%`, `"$"#,##0`, `"$"#,##0.00`, `yyyy-mm-dd`, `mmm yyyy`. Existing workbook/reference, and domain conventions take priority;
- Percentages: Follow the domain or reference's precision. Otherwise, use 1 decimal for most analytical cells, 0 decimals for dashboard outputs, and 2 decimals where small rate differences matter.
- Do not swap `.` and `,` in format codes to mimic locale separators; separators are controlled by spreadsheet/render locale. Use `0.0%`, not `0,0%`, and `#,##0`, not `#.##0`.
- Choose the appropriate format for readability. Match precision to meaning: counts use `#,##0`; rates usually use `0.0%` or `0.00%`; currency uses whole units unless cents matter.

### Verification Rules
Before final response, apply these checks within the authorized changes and their dependencies. Report unrelated pre-existing defects without repairing them.

1. Inspect key ranges:
` ` `js
const check = await workbook.inspect({
  kind: "table",
  range: "Dashboard!A1:H20",
  include: "values,formulas",
  tableMaxRows: 20,
  tableMaxCols: 12,
});
console.log(check.ndjson);
` ` `

2. Scan formula errors:
` ` `js
const errors = await workbook.inspect({
  kind: "match",
  searchTerm: "#REF!|#DIV/0!|#VALUE!|#NAME\\?|#N/A|#NUM!|#NULL!|#SPILL!|#CALC!",
  options: { useRegex: true, maxResults: 300 },
  summary: "final formula error scan",
});
console.log(errors.ndjson);
` ` `

3. Render sheets/ranges to verify visual output (skip if already verified and no style changes):
` ` `js
const blob = await workbook.render({ sheetName: "Sheet1", range: "A1:H20", scale: 2 });
` ` `
For creation or broad authorized restructuring, visually review every sheet. For a narrow edit, review the changed view and affected dependencies, then compare all tabs with the source for unintended value, formula, object, validation or style changes. Do not repeatedly render unchanged tabs; investigate any scope-preservation failure.

Visual requirements:
- Fix severe defects before finalizing: blank/broken charts, low-contrast text, unreadable font sizes, clipped headers/numbers or chart data/axis labels, obvious formula errors, default blank sheets, or content outside the visible working area.
- Ensure logical labels or titles appear once and have a clear layout
- Ensure text is visible and columns/rows are appropriately sized; verify chart labels, axis ticks and fonts at normal zoom.


4. Keep verification compact:
- Use Artifact Tool to verify requested features and results, reusing checks for unchanged content.
- Investigate the saved file further only when there is a specific export concern.
- Avoid arbitrary formula count checks, assumptions about file storage, and huge NDJSON dumps.

5. Export:
` ` `js
await fs.mkdir(outputDir, { recursive: true });
const output = await SpreadsheetFile.exportXlsx(workbook);
await output.save(`${outputDir}/output.xlsx`);
` ` `

6. Finalize immediately after successful export and checks above.
- Do not export extra `.xlsx` variants unless asked.

### Citation Requirements
- Cite sources inside the spreadsheet
- Use plain-text URLs in spreadsheet cells.
- For financial models, preserve provenance through existing source conventions, a compact source table or an existing supported cell annotation. Prefer a table for repeated inputs; do not force a new table into a narrow edit.
- Do not add cell comments or cell notes unless the user requests them. Preserve existing annotations; put needed new source or assumption context in ordinary cells within scope.
- For researched row-wise data tables, include source URLs in a dedicated source column.
- When comments are requested, keep them succinct, minimal and easy to read.
- Use one supported annotation path per cell; update an existing note/thread rather than layering another system over it. Reject duplicate cell references in a legacy comment part. Repair the authoring path rather than deleting provenance to make export succeed.

## Completion Criteria
### Criteria for Question / Read only requests
- Answer from the available workbook context. Do not edit or overwrite unless the user asks for a workbook change.

### Criteria for all create and edit requests
Complete only when:
- Content is populated, addresses the user's request, and formulas compute, with no obvious formula errors in key scanned ranges (including bad-reference, off-by-one or circular errors).
- `.xlsx` saved to `outputs/<unique_thread_id>/`.
- Visual verification passes: organized, legible layout matches requested style or default/existing edit baseline; all important numbers/callouts are visible; numbers, text, charts and content are unclipped without awkward wrapping.
- Required controls, charts, panes and requested features exist.

## Error Recovery
On first tool or API error:
1. Read error text.
2. Consult the selected workflow's targeted help or schema discovery only if needed.
3. Retry with minimal patch (not full rewrite).
4. Continue from existing workbook state.

Do not loop indefinitely on similar failures.

## Final response citations

Place :codex-file-citation{...} inline in prose without wrapping it in backticks or a code block, not in a trailing list. Use `purpose="source"` for Q&A/no-op and `purpose="output"` for create/edit.

- [HARD REQUIREMENT] Create/edit: cite each final workbook exactly once with a plain output citation. Summarize representative changes; do not cite every sheet/range or add a separate filename, path, or Markdown link. Example: `Created :codex-file-citation{path="/abs/path/inventory.xlsx" purpose="output"} with formula-driven status and a summary.`
- Q&A: cite whole-workbook claims plainly; otherwise use the narrowest reliable `sheet` + `range` (the exact cell for a discrete value). Cite discontiguous cells separately. For objects, use `sheet` + exact inspected `object_id`; add `object_kind`/`label` only when useful. Never cite a sheet alone or guess locators.
- Calculations: cite only distinct inputs, drivers, formulas, or results the answer needs.

:codex-file-citation{path="/abs/path/book.xlsx" purpose="source" artifact_kind="workbook" sheet="Revenue Model" range="C27"}

Never cite intermediates unless asked.

## Comment Author
- If the authenticated/user profile or env context provides a user display name, use it as the threaded comment display name unless the user requests another name. Default to `User`.

## Source, PDF, and Attachment Processing
- Keep source notes compact: record file name, section/table label, and enough context to audit the number. Do not paste large PDF excerpts into the workbook unless requested.
- Bundled Python libraries available in the bundled runtime environment for extraction/analysis include `pandas`, `numpy`, `pypdf`, `python-docx`, and `reportlab`. You may read/extract in separate scripts if needed.
- Bundled JS libraries available for document/PDF work include `docx`, `pdf-lib`, and `pdfjs-dist`.

TASK
# Find the payout mismatches

Compare `stripe_payouts.csv` with `bank_deposits.csv`.

Each Stripe row names the expected bank deposit after its fee. A matching bank deposit has the
same payout id, the expected amount, and a date no more than two calendar days after the payout.
Find these problems: a missing deposit, a deposit short by the Stripe fee, a duplicate deposit,
a deposit more than two days late, and a bank deposit with no Stripe payout.

Write `mismatches.csv` with exactly this header:

` ` `csv
id,kind,amount
` ` `

Use the payout id for payout-side problems and the bank deposit id for a bank-only problem.
`amount` should be the missing or extra amount for missing, short, duplicate, and bank-only rows;
for a late deposit, use the deposit amount. Use a short plain label in `kind`.

# Workflows for creating new spreadsheets

## Quality Guidelines
- Build correct, readable, auditable workbooks for the intended audience; keep them simple and easy to update.
- Before populating, identify the audience, decision, target engine, outputs, inputs, calculations and checks from the user request, reference/template and applicable domain guidance. These roles do not require tabs: combine compatible roles and add tabs only for distinct readers, dependencies, refresh boundaries, auditability or an explicit request.
- Do not create a tab for a small supporting block that fits cleanly in an existing sheet.
- State recommendations plainly and support them with the few decisive facts or rule already shown in the workbook; avoid generic rationale, invented scoring or formula-generated prose.
- Cap oversized widths/heights after autofit/wrapping.

## Checks
- Do not add a separate "Checks" tab for simple spreadsheets. Only add when useful for task/complexity.
# Using artifact_tool APIs (JavaScript)

Library version: 2.8.58+

## Required imports, setup and exports
` ` `js
import fs from "node:fs/promises";
import { FileBlob, SpreadsheetFile, Workbook } from "@oai/artifact-tool";

// To import existing workbook
const input = await FileBlob.load("path/to/input.xlsx");
const workbook = await SpreadsheetFile.importXlsx(input);

// To create a new workbook and add a sheet to it
const workbook = Workbook.create();
const sheet = workbook.worksheets.add("Inputs");

// To export
await fs.mkdir(outputDir, { recursive: true });
const output = await SpreadsheetFile.exportXlsx(workbook);
await output.save(`${outputDir}/output.xlsx`);
` ` `

Import CSV text directly when the source or intermediate data is CSV:
` ` `js
const csvText = await fs.readFile("path/to/input.csv", "utf8");
const workbook = await Workbook.fromCSV(csvText, { sheetName: "Sheet1" });
` ` `
Prefer `Workbook.fromCSV(...)` over hand-parsing CSV rows; clean or analyze CSV with Python/Node first only when needed.
CSV fields import as strings. Convert intended numeric/date columns before calculations; number formatting alone does not convert text to numbers.


## Build Patterns
- Prefer block writes (`range.values`, `range.formulas`) over per-cell loops. Normally match the matrix shape to the target range (e.g. "D4:M4" → 1×10). To intentionally expand a larger matrix from an anchor, target a single cell or use range.write(matrix).
- `range.values = [[value]]` repeats that value across the range; range.formulas does not broadcast a single formula. For merged ranges, write to the top-left cell or `mergedRange.values = [[value]]` where `mergedRange` is a single merged range.
- Seed scalar formulas once, then `fillDown()` / `fillRight()`. For dynamic-array formulas (`SEQUENCE`, `UNIQUE`, `FILTER`, `SORT`, `VSTACK`, `HSTACK`), write only the anchor cell and let the result spill after.
- Use `range.displayFormulas` plus `range.formulaInfos` when you need to understand a spill child or a data-table output cell.
- Formula calculation automatically happens.
- Prefer real `Date` objects for sortable/charted/formula date columns.
- Number and date formats must be applied explicitly (for example `yyyy-mm-dd`).
- Use JSON-serializable values for non-Date cells: `string | number | boolean | null`.
- If a cell is intended to display literal text that begins with `=`, write it as a value prefixed with a single quote (for example `'=B2*C2`). This includes formula descriptions, validation examples, and labels; do not write these cells through `range.formulas`.
- Create every worksheet referenced by formulas before writing any cross-sheet formulas.
- Verify with `await workbook.inspect(...)`; use `workbook.help(...)` only when the quick surface below is insufficient.
- `render` can be used to examine an existing workbook visually and for visual verifications.

## Conventions
- Use camelCase API names and option keys.
- Cell/range addressing: A1 notation (`sheet.getRange("A1:C10")`).
- Drawing anchors (`sheet.charts`, `sheet.shapes`, `sheet.images`): 0-based `{ row, col }`.
- Drawing offsets/extents use pixels (`rowOffsetPx`, `colOffsetPx`, `widthPx`, `heightPx`).

## API Discovery Policy (Strict)
- Use this quick API surface first.
- Use `workbook.help(...)` only when the supplied public documentation leaves a required operation unclear. Start with one bounded exact feature/path lookup, such as `range.dataValidation` or `chart.series.add`.
- If that lookup returns no useful match, one bounded reformulation is allowed. Stop after those two attempts; do not repeat similar queries, inspect package internals/prototypes/nearby tests, or invent enum values and setters. Use a documented equivalent that preserves the task.

## Supported Formulas
- Look up formula syntax with `fx.<formula>`, e.g. `workbook.help("fx.PMT", { include: "index,examples,notes", maxChars: 3000 })`. A help entry does not guarantee working calculation or Excel export.
- To browse a family of formulas, use `fx.*` with a category regex. Useful categories: `financial`, `math-trig`, `statistical`, `lookup-reference`, `logical`, `text`, `date-time`, `information`, `engineering`, `database`.
- For intent-based lookup, use a short natural query plus a narrow `search` regex of likely functions.
- Keep `maxChars` bounded; if results are noisy, narrow `search` rather than issuing many similar queries.

` ` `
console.log(workbook.help("fx.PMT", { include: "index,examples,notes" }).ndjson);
console.log(workbook.help("fx.*", { search: "financial", include: "index,examples", maxChars: 4000 }).ndjson);
console.log(workbook.help("lookup with fallback", { search: "XLOOKUP|INDEX|MATCH|IFERROR", include: "index,examples,notes", maxChars: 4000 }).ndjson);
` ` `

### Known formula/export limitations (not exhaustive)
If a formula fails, use a verified equivalent that preserves the intended result.

Known issues:
- Avoid `MAP`, `REDUCE`, `SCAN`, `MAKEARRAY`, `GROUPBY`, `PIVOTBY`. Use helper cells and supported scalar formulas;
- Prefix `XLOOKUP`, `TEXTJOIN`, `MINIFS`, `MAXIFS`, `IFS`, and `RANK.EQ` with `_xlfn.`, including nested calls: e.g. `'=_xlfn.TEXTJOIN(", ",TRUE,B2:C2)'`.
- For `LET`, `LAMBDA`, `BYROW`, and `BYCOL`, prefix function names with `_xlfn.` and every LET/LAMBDA local-variable declaration and reference with `_xlpm.`.
- PivotTable APIs exist, but XLSX export is unreliable; use formula summaries.
- `COUNTIF` / `COUNTIFS` with an empty-string criterion can miss blank cells, even in bounded ranges. For unconditional blank counts, use `COUNTBLANK(range)`.


## Reading existing/imported workbooks
- On existing/imported workbooks, get a compact summary via `inspect` to understand what already exists and where.
- Prefer `inspect(...)` for workbook understanding and discovery across broad areas.
- Prefer direct getters like `range.formulas` when you already know the target range and need the exact rectangular formula matrix.
- If formula locations are unknown, prefer `inspect({ kind: "formula", ... })` over reading `range.formulas` across a very large area.
- Prefer to set `maxChars`, `tableMaxRows`, `tableMaxCols`, and/or `maxResults` to prevent large dumps of data.
- For suspicious or high-impact outputs, use `workbook.trace("Sheet!A1")` to audit the dependency tree from final output/check cell back to source cells. Trace output can be large, so summarize by depth/node count before logging.

### Inspect for workbook understanding
- Compact summary:
` ` `js
await wb.inspect({
  kind: "workbook,sheet,table",
  maxChars: 6000,
  tableMaxRows: 6,
  tableMaxCols: 6,
  tableMaxCellChars: 80,
});
` ` `
- Quick overview of sheet ids and names: `await wb.inspect({ kind: "sheet", include: "id,name" })`
- Formula discovery in a targeted area: `await wb.inspect({ kind: "formula", sheetId: firstSheetName, range: "A1:Z30", maxChars: 2500, options: {maxResults:50} })`
- Checking existing styles in a targeted area: `await wb.inspect({ kind: "computedStyle", sheetId: firstSheetName, range: "A1:E10", maxChars: 2500 })`
- Common `kind` tokens: `workbook`, `sheet`, `table`, `region`, `match`, `formula`, `thread`, `computedStyle`, `definedName`, `drawing`
- Inspects can also be used to zoom in on specific areas, especially for target edits:
` ` `js
await wb.inspect({
  kind: "region",
  sheetId: firstSheetName,
  range: "A1:Z30",
  maxChars: 2500,
});
` ` `
- Inspect output may include JSON records with `"id"` values (for example `"ws/r5qsk5"`), which you can resolve back to workbook objects with `wb.resolve(...)`:
- `wb.resolve("ws/...")` -> worksheet
- `wb.resolve("th/...")` -> comment thread

## Known Gotchas (Do not repeat)
- Do not set undocumented attributes on remote objects.
- `Workbook.create()` starts with no sheets; add one before calling `getActiveWorksheet()`.
- Create every worksheet referenced by formulas before writing cross-sheet formulas.
- Prefer bounded formula ranges, e.g. `$A$6:$A$205`. Full-column references can be truncated to each column's populated extent: unequal extents can make `COUNTIFS` / `SUMIFS` return `#VALUE!`, and `ROWS` / `INDEX` can differ from Excel.
- If export fails, isolate the cause by checkpoint-export after major blocks to isolate the cause: base sheets, values/formulas, formatting, conditional formatting, tables, charts/rendering. For charts, first simplify optional styling first: nested border configs, custom chart axis/series mutations, broad autofit/formatting, then nonessential drawings.

## Quick API Surface (High-Value + Common)

### Core workbook/file APIs
- `import { FileBlob, SpreadsheetFile, Workbook } from "@oai/artifact-tool"`
- `const workbook = Workbook.create()` to create an empty workbook
- `const sheet = workbook.worksheets.add("Sheet1")` to add a sheet
- `const workbook = await SpreadsheetFile.importXlsx(arrayBufferOrFileBlob)`
- `const xlsx = await SpreadsheetFile.exportXlsx(workbook); await xlsx.save("output.xlsx")`
- `const inspect = await workbook.inspect({ kind: "sheet", include: "id,name", sheetId, range: "A1:C10" })`
- `const help = workbook.help("worksheet.getRange", { include: "index,examples" })`
- Preferred: `const preview = await workbook.render({ sheetName: "Sheet1", autoCrop: "all", scale: 1, format: "png" })`
- To get the bytes and/or save the blob to file:
` ` `js
const previewBytes = new Uint8Array(await preview.arrayBuffer());
await fs.writeFile(`${outputDir}/preview.png`, previewBytes);
` ` `
- `const workbook = await Workbook.fromCSV(csvText, { sheetName: "Sheet1" })`
- `await workbook.fromCSV(csvText, { sheetName: "ImportedData" })` requires an empty workbook; it does not append CSV to a populated workbook. Prefer static `Workbook.fromCSV(...)`.

### Worksheet selection/creation
- `workbook.worksheets.add(name)`
- `workbook.worksheets.getItem(name)`
- `workbook.worksheets.getItemAt(index)`
- `workbook.worksheets.getActiveWorksheet()` (only after at least one sheet exists)

### Worksheet operations
- `sheet.getRange("A1:C10")`, `sheet.getRangeByIndexes(startRow, startCol, rowCount, colCount)`, `sheet.getCell(row, col)`
- `sheet.getUsedRange(valuesOnly?)`
- `sheet.freezePanes.freezeRows(rowCount)`, `sheet.freezePanes.freezeColumns(columnCount)`, `sheet.freezePanes.unfreeze()`
- `sheet.tabColor = "#1F4E78"` sets the worksheet tab color; the getter returns a `Color` object.
- `sheet.tables`, `sheet.charts`, `sheet.sparklineGroups` (`sheet.sparklines` alias), `sheet.shapes`, `sheet.images`
- `sheet.showGridLines = false`
- `sheet.dataTables`, `sheet.conditionalFormattings`, `sheet.dataValidations`
- `sheet.deleteAllDrawings()` removes all drawings, including charts, shapes, and images.

### Range values/formulas
- `const range = sheet.getRange("A1:C10")`
- `range.values = [[...], ...]` (2D matrix of values).
- `range.formulas = [["=..."], ...]`
- `range.formulasR1C1 = [["=RC[-1]*2"]]`
- To read: `range.values` / `range.formulas` / `range.displayFormulas` / `range.formulaInfos` (for spill/array formulas)
- `range.write(matrixOrPayload)` (auto-sizes/spills from anchor as needed)
- `range.writeValues(matrixOrRows)`
- `range.fillDown()`, `range.fillRight()`
  - `sheet.getRange("D2").formulas = [["=..."]]`
  - `sheet.getRange("D2:D200").fillDown()`
- `range.clear({ applyTo: "contents" | "formats" | "all" })` clears cell contents, formatting, or both; drawings remain.
- `range.copyFrom(sourceRange, "values" | "formulas" | "all")`. Prefer matching shapes; a single-cell value source can broadcast across a larger destination.
- `range.copyTo(destRange, "values" | "formulas" | "all")`
- `range.offset(rowOffset, colOffset)`, `range.resize(rowCount, columnCount)`, `range.getCurrentRegion()`, `range.getRow(i)`, `range.getColumn(j)`
- `range.getRangeByIndexes(startRow, startCol, rowCount, colCount)`, `range.getCell(row, col)` (relative to the range)

### Formatting
- `range.format` supports `fill`, `font`, `numberFormat`, `borders`, alignments, `wrapText`
- `range.format.verticalAlignment = "center"` maps to Excel Middle Align
- `range.format.autofitColumns()`, `range.format.autofitRows()`
- Excel unit sizing:  `range.format.columnWidth = 18`, `range.format.rowHeight = 24`
- Pixel sizing: `range.format.columnWidthPx = 120`, `range.format.rowHeightPx = 24`
- `range.setNumberFormat("yyyy-mm-dd")`
- `range.format.numberFormat = [["0"], ["0.00"], ["@"]]`
- Borders: There are two ways to set borders on a range (1) simple form (2) per edge form. Example:
` ` `js
// (1) Preferred simple form
// `preset` can be "none" | "outside" | "inside" | "all" | "doubleBottom"
// "outside" will just set borders on the outside edges of the range.
// `style` are Excel/OpenXML-style names such as "thin", "medium", "thick", "dashed", and "dotted".
range.format.borders = { preset: "all", style: "thin", color: "#D9D9D9" };

// (2) Per-edge form. Use top/bottom/left/right, not edgeTop/edgeBottom/etc.
// Format: {style?: string; color?: ColorConfig; weight?: number;}
// Prefer setting `style` over `weight` unless you want granular control.
range.format.borders = {
  insideHorizontal: { style: "thin", color: "#D9D9D9" },
  insideVertical: { style: "medium", color: "#D9D9D9" },
  top: { style: "thick", color: "#D9D9D9" },
  bottom: { style: "dashed", color: "#D9D9D9" },
  left: { style: "dotted", color: "#D9D9D9" },
  right: { style: "thin", color: "#D9D9D9" },
};
` ` `

### Data Validation
- `range.dataValidation = { rule: { type: "list", formula1: "Categories!$A$2:$A$4" } }`
- `range.dataValidation = { rule: { type: "list", values: ["Not Started", "In Progress"] } }`
- `sheet.dataValidations.add({ range: "B2:B100", rule: { type: "whole", operator: "between", formula1: 1, formula2: 10 } })`

### Conditional formatting
- Use `range.conditionalFormats.add(ruleType, ConditionalFormatConfig);`.
- Use `range.conditionalFormats.add(ruleType, {operator, formula, format});`. Choose ruleType, operator, color, and style strings from the inline types below.
` ` `
type ConditionalFormatRuleType =
  | "cellIs" | "CellValue" | "Custom" | "expression"
  | "colorScale" | "dataBar" | "iconSet"
  | "containsText" | "notContainsText" | "beginsWith" | "endsWith"
  | "containsBlanks" | "notContainsBlanks" | "containsErrors" | "notContainsErrors"
  | "duplicateValues" | "uniqueValues" | "timePeriod" | "top10" | "aboveAverage";

type CellIsOperator =
  | "greaterThan"
  | "greaterThanOrEqual"
  | "lessThan"
  | "lessThanOrEqual"
  | "equal"
  | "notEqual"
  | "between"
  | "notBetween";

type ConditionalFormatConfig =
  | { operator: CellIsOperator; formula: string | number | Array<string | number>; format?: DifferentialFormatConfig }
  | { formula: string | number; format?: DifferentialFormatConfig }
  | { colors?: ColorConfig[]; thresholds?: CfvoInput[] }
  | { color?: ColorConfig; thresholds?: CfvoInput[]; gradient?: boolean }
  | { iconSet: string; showValue?: boolean; reverse?: boolean; thresholds?: CfvoInput[] }
  | { text: string; format?: DifferentialFormatConfig }
  | { timePeriod: "yesterday" | "today" | "tomorrow" | "last7Days" | "lastWeek" | "thisWeek" | "nextWeek" | "lastMonth" | "thisMonth" | "nextMonth"; format?: DifferentialFormatConfig }
  | { rank?: number; percent?: boolean; bottom?: boolean; format?: DifferentialFormatConfig }
  | { aboveAverage?: boolean; equalAverage?: boolean; stdDev?: number; format?: DifferentialFormatConfig };

type DifferentialFormatConfig = {
  fill?: FillConfig;
  font?: { bold?: boolean; italic?: boolean; color?: ColorConfig };
  border?: RangeBordersConfig; // Per-edge top/bottom/left/right only; presets are ignored here.
  numberFormat?: string;
};

type CfvoInput =
  | "min"
  | "max"
  | number
  | `${number}%`
  | { type: "min" | "max" | "num" | "percent" | "percentile"; value?: string | number };
` ` `
- Rule types (`ConditionalFormatRuleType`): "cellIs" | "CellValue" | "Custom" | "expression"
  | "colorScale" | "dataBar" | "iconSet"
  | "containsText" | "notContainsText" | "beginsWith" | "endsWith"
  | "containsBlanks" | "notContainsBlanks" | "containsErrors" | "notContainsErrors"
  | "duplicateValues" | "uniqueValues" | "timePeriod" | "top10" | "aboveAverage";
- XLSX `iconSet` names: `3Arrows`, `4Arrows`, `5Arrows`, `3ArrowsGray`, `4ArrowsGray`, `5ArrowsGray`, `3TrafficLights1`, `3Signs`, `4RedToBlack`, `3TrafficLights2`, `4TrafficLights`, `3Symbols`, `3Flags`, `3Symbols2`, `5Quarters`, `4Rating`, `5Rating`. Avoid `3Stars`, `3Triangles`, and `5Boxes`: their current XLSX serialization is not reliable.
- Custom conditional formatting: `range.conditionalFormats.addCustom(expression, {fill, font, border});`
- `range.conditionalFormats.deleteAll()` / `range.conditionalFormats.clear()`

` ` `js
const grid = sheet.getRange("B2:J10");
grid.conditionalFormats.add("colorScale", {
  colors: ["#2563EB", "#FDE047", "#DC2626"],
  thresholds: ["min", { type: "percentile", value: 50 }, "max"]
});
` ` `

### Tables
- When adding new tables, set explicit unique names (`TasksTable`, `SummaryTable`).
- Do not overlap tables; the API does not reject overlaps. Check existing table ranges in the initial compact `inspect` summary before adding one.
- `const table = sheet.tables.add("A1:H200", true, "TasksTable")`
- `table.rows.add(null, [[...], ...])`, `table.getDataRows()`, `table.getHeaderRowRange()`
- Read tables: `sheet.tables.items` -> `Table[]`
- Set + Getters: `table.name`, `table.style`, `table.showHeaders`
- Toggles for table utilities (set/get): `table.showTotals`, `table.showBandedColumns = true`, `table.showFilterButton`
- `table.delete()`

### Images
- `sheet.images.add({dataUrl: "data:image/png;base64,...", anchor: {from: { row: 1, col: 2 }, extent: { widthPx: 160, heightPx: 120 }}})`


### Threaded Comments
This is the API to create a threaded comment in Excel, which requires a user-visible author.
- Required: Before adding a comment, create its visible author with `workbook.comments.setSelf({"displayName": <user_display_string>})`, where `<user_display_string>` is a string such as "User"
- Create a new thread with a single comment: `const thread = workbook.comments.addThread({"cell": sheet.getRange("E2")}, "Source: <website>")`
- To reply to a threaded comment: `thread.addReply("This is a reply to the comment")`
- To resolve/re-open a thread: `thread.resolve()`, `thread.reopen()`

### Charts
- Place charts in reserved blank areas with gutter rows/columns; do not cover data.
- Prefer range-backed charts so source edits update the chart. Headers are detected when the first row contains text and no numeric cells.


#### Fast-chart path
- For contiguous data: pass categories first, then one column per series:
  ` ` `js
  sheet.getRange("F4:H6").values = [
    ["Month", "Revenue", "EBITDA"],
    ["Jan", 100, 10],
    ["Feb", 120, 18],
  ];
  const chart = sheet.charts.add("line", sheet.getRange("F4:H6"));
  ` ` `
- For nonadjacent columns: pass equal-height, single-column ranges with categories first:
  ` ` `js
  const chart = sheet.charts.add("bar", [
    sheet.getRange("A1:A10"),
    sheet.getRange("D1:D10"),
    sheet.getRange("G1:G10"),
  ]);
  chart.series.items[0].fill = "#F472B6";
  ` ` `
- Both paths create source-cell references and show a bottom legend. Apply requested formatting once after creation:
` ` `js
chart.setPosition("J4", "Q20"); // always set
# Style and Formatting Instructions

Follow user instructions, then intentional templates/references, then domain guidance. Defaults apply only to new sheets or authorized restyling.

Render before editing. Preserve unrelated content, layout, formatting and native features; values-only edits must not change formatting.

## Tab Structure Defaults
- Order and group tabs by reader workflow. Keep primary views and related working sheets together; group supporting calculations, checks and sources separately when separate tabs are needed.
- Keep needed assumptions/guidance accessible. 
- Add divider tabs only when useful in complex workbooks; leave ordinary tabs uncolored but add consistent tab color when it aids navigation.

## Reader-facing sheet layout

For new reader-facing sheets or authorized restyling, default to a compact reader-facing layout.

- Use a concise unfilled left-aligned title, thin rule, short context/subtitle and modest whitespace before the main content. Avoid large filled title banners.
- Keep the title stack short; move detailed sources, caveats and maintenance notes to an existing Sources/Notes area or side area.
- Add summary/KPI cards only when they clarify the requested decision; do not duplicate a small table or make oversized cards.
- Choose cards, tables and charts for the task; keep useful trends and comparisons rather than defaulting every summary to a table.

## Use a visually clear layout
- Distinguish headers, inputs, calculations and notes consistently. Default to dark body text and restrained fills, not a universal teal theme; preserve domain styling defaults, like finance input/formula/source colors and dynamic statuses.
- Use modest spacing and consistent row heights, especially within the same section. Expand for wrapped content; format only populated or intentionally reserved ranges.
- Keep working titles, headers and input/calculation areas unmerged. Presentation merges require user/template intent; never overwrite content or combine distinct table columns. For requested spanning headers, use supported Center Across Selection over otherwise empty cells.
- For new reader-facing sheets or authorized restyling, use a compact table-first front page: concise unfilled title, short context line, modest whitespace, then the decision/table. Do not replace it with a large filled banner or KPI-card grid unless requested or it clearly improves the decision.
- Use yellow/amber for inputs needing updates; follow documented exception styles for overrides, special formulas and one-offs. Label failed checks; add a compact legend when colors have multiple meanings.
- Dark column headers: white text with thin white separators between actual headings, including dates.
- Section bands: continuous fill and one outside outline, without internal borders; exclude gutters.
- If a sheet uses a leading gutter, keep it consistent: align titles, sections and tables to the same content edge; do not use gutter columns for notes, units or data.
- Prefer thin/light structural borders, stronger section breaks and no full body-cell grid. Do not apply borders around every filled cell. 
- Hide gridlines where styling defines reader-facing structure; retain useful working gridlines.
- Put needed context in separate cells or ordinary punctuation. Preserve meaningful financial/mathematical labels and symbols, required source quotes, intentional reference conventions and the expressly specified plain `x` navigation markers;
- Conditional Formatting is preferred over manually painted cells when applying styles consistently over a range, column or table.
- Use bounded conditional formatting for dynamic status, risk, priority, variance, threshold and exception cues when they aid scanning or must react to edits; do not use it for decoration or substitute static fills.

## Freeze panes

- Freeze rows/columns only when they keep useful headers or identifiers visible while scrolling, using the smallest useful frozen area. Leave enough space to read and work with the data.
- Do not move content or add tabs to accommodate freezing. Preserve existing panes during unrelated edits.
- Do not freeze compact summary, dashboard or cover sheets unless scrolling requires preserving shared headers or row labels.

## Align and format by data type

- Left-align text, right-align numbers and center column headers horizontally/vertically. Top-align wrapped descriptions where helpful.
- Keep numbers/dates typed with explicit, appropriate formats and clear units. Adjust widths/heights so final content with formatting fits (including signs, parenthesis and units); never stringify values for appearance.
- Italicize brief context/scope/unit notes—not headers, controls, statuses or warnings.

## Use typography intentionally but conservatively

- Resolve fonts once: use the first verified in both generating and target environments, Helvetica Neue → Helvetica → Arial → Aptos. Record availability and fallbacks; unverified does not mean unavailable.
- Use one family across cells, charts and theme fonts, with consistent body sizing. Keep titles and key metrics only modestly larger; spacing and restrained fills can be used for hierarchy.
- Keep font sizes consistent and the same outside of visual dashboard/hero tabs and headers or titles.
  - Do not vary font size of rows inside the same table.
  - If specific rows or column callouts are needed, use bold/italics sparingly. For example for totals or when needed for domain styling defaults.

## Live inputs and visuals

- Drive dependent values, charts and status text from editable cells. Use conditional formatting for useful status/exception cues and categorical validation where feasible. Invalid/missing inputs must not appear as plausible zeros or success states.
- Prefer compact, formula-linked summaries. Preserve required outputs; avoid redundant tables and oversized KPI cards. Inline bars require explicit request. Follow `features/charts.md` for charts.

## Verification

Inspect the saved workbook at normal zoom, with cells unselected. Check every tab for consistency, readable wrapping and unclipped content. Verify live states, conditional-format ranges, effective fonts and saved freeze panes.

24:Import CSV text directly when the source or intermediate data is CSV:
27:const workbook = await Workbook.fromCSV(csvText, { sheetName: "Sheet1" });
29:Prefer `Workbook.fromCSV(...)` over hand-parsing CSV rows; clean or analyze CSV with Python/Node first only when needed.
30:CSV fields import as strings. Convert intended numeric/date columns before calculations; number formatting alone does not convert text to numbers.
140:- `const workbook = await Workbook.fromCSV(csvText, { sheetName: "Sheet1" })`
141:- `await workbook.fromCSV(csvText, { sheetName: "ImportedData" })` requires an empty workbook; it does not append CSV to a populated workbook. Prefer static `Workbook.fromCSV(...)`.
