  "deviations": [
    "README 'Build from source' -> scripts/build-app.sh: requires macOS (swift build --triple *-apple-macosx14.0, sips, iconutil, lipo); not runnable on Ubuntu. Not executed.",
    "README 'Inside the app' -> swift scripts/check-strings.swift: requires a Swift toolchain, which is absent and not installable via apt in this guest. Not executed.",
    "No .github/workflows directory exists in the pinned checkout, so no CI command was available."

  "main_blocker": "macOS-only product and no Swift toolchain on Linux guest",
  "operation": "None exercised. Intended operation: scripts/build-app.sh (README 'Build from source'), which produces build/Tendedero.app; also 'swift scripts/check-strings.swift' (README Inside the app) for translation checks.",
  "operation_scope": "Product is a macOS 14+ AppKit/SwiftUI app. Build needs macOS Command Line Tools/Swift toolchain, swift build with apple-macosx14.0 triples, sips, iconutil, lipo. Guest is Ubuntu 24.04 Linux; no swift/swiftc on PATH and no Swift package in apt. Nothing runnable on Linux that exercises the product.",
  "outcome": "blocked",
  "steps": [
    "Read README.md (no install/build commands run on Linux beyond inspection)",
    "Read scripts/build-app.sh and scripts/check-strings.swift",

  "suggested_fix": "Run on a macOS 14+ host with Xcode or Command Line Tools: scripts/build-app.sh, then open build/Tendedero.app. Or install a Linux Swift toolchain (swift.org tarball, not apt) to run swift scripts/check-strings.swift, which is a translation checker and not product functionality."
