excel-toolchain
description (verbatim frontmatter)
Durable, autoresolving Excel toolchain for cwc-finance on the developer Mac (darwin-arm64) — typed manifest (toolchain.json) + validate.py doctor/resolve, modeled on cwc-engineering's durable-mac-toolchain. Use on "excel toolchain", "fix excel setup", "xlwings", "recalc setup", when an Excel script fails with "command not found: uv", an import error on openpyxl/xlwings/pydantic/yaml, or AppleScript error -1743, and as step 0 of EVERY cwc-finance Excel script (validate.py --resolve, programmatic). Never free-recall a check or install command — copy validator output verbatim.
