LICENSE.md: Relicensed: BSD-3-Clause → BSD-3-Clause AND proprietary (2018-01-03) → BSD-3-Clause (2020-03-29).github/CONTRIBUTING.md:54: states a policy on AI-generated contributions.github/CONTRIBUTING.md:227: names Linux Foundation
Architecture & Codebase — including AI provenance
strongcalc.go is 19,693 lines, 45× this codebase's median file
adequateThe median source file here is 434 lines. 2 files exceed 4,340 lines, the largest being 19,693. Size is not a defect on its own — some problems genuinely live in one place — but these are where merge conflicts, review fatigue and single-owner knowledge concentrate, and they are the first thing that slows an inheriting engineer down.

19 advisories against this project in the last 24 months, 12 high or critical, 15 fixed in no release yet
adequateThe newest was published on 2026-10-03. A project that publishes advisories is telling its users about its fixes, and the count and pace say how much security work it carries. GHSA-mx22-3794-2vpv (high), GHSA-jw42-f3rr-4cc3 (high), GHSA-r7x5-4969-99p7 (high) and 12 more affect 2.11.0, the newest release, and not the surveyed commit: their fixes are in the surveyed commit and in no release. Answer lives in: the version you run.
| 2026-10-03: GHSA-mx22-3794-2vpv (high), fixed in the surveyed commit and in no release: Excelize: Unchecked pivot-cache field index in extractPivotTableFields causes unrecoverable panic |
| 2026-09-30: GHSA-jw42-f3rr-4cc3 (high), fixed in the surveyed commit and in no release: Excelize: Unbounded row number in Rows.Columns makes GetRows and the Rows iterator loop for days |
| 2026-09-29: GHSA-r7x5-4969-99p7 (high), fixed in the surveyed commit and in no release: Excelize: Nil-pointer dereference in GetSlicers when a worksheet has extLst present but no drawing element |
| 2026-09-15: GHSA-2j4c-ffch-9f23 (high), fixed in the surveyed commit and in no release: Excelize Decrypt: unrecoverable panics on malformed OLE/CFB encrypted workbooks |
| 2026-09-12: GHSA-x2q3-8cjh-766f (high), fixed in the surveyed commit and in no release: Excelize: extractPart allocates attacker-controlled, unbounded and negative-sized buffers from CFB directory entries: remote panic / OOM DoS |
