rxhanson/rectangle: technical due diligence, read from its repository
What Borehole read in rxhanson/rectangle's code and history at b2e5709: its licence, security advisories, releases, review practice, tests, dependencies and operations. Every finding cites the file and line it rests on. The full report also covers the team and asks the questions the code cannot answer.

Architecture & Codebase — including AI provenance
strongRectangle/WindowManager+CooperativeCornerResize.swift is 1,546 lines, 31× this codebase's median file
adequateThe median source file here is 49 lines. 3 files exceed 1,000 lines, the largest being 1,546. 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.
Rectangle/WindowManager+CooperativeCornerResize.swift:1 — 1,546 lines (31× median) |
Rectangle/CooperativeCornerResize.swift:1 — 1,452 lines (29× median) |
Rectangle/WindowAction.swift:1 — 1,174 lines (23× median) |
Engineering Process & SDLC Maturity
adequateTests cover a thin slice of the codebase
adequate5 test files against 199 source files (2.5%). This does not measure whether the tests are good, only whether enough of them exist for the codebase to be changed safely by someone who did not write it — which is exactly the situation after an acquisition.
