files-community/files: technical due diligence, read from its repository
What Borehole read in files-community/files's code and history at 0e3c17c: 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
strongsrc/Files.App/ViewModels/ShellViewModel.cs is 3,579 lines, 63× this codebase's median file
adequateThe median source file here is 56 lines. 11 files exceed 1,000 lines, the largest being 3,579. 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.

Engineering Process & SDLC Maturity
adequateTests cover a thin slice of the codebase
adequate22 test files against 1,171 source files (1.9%). 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.
| 22 test files / 1,171 source files |
Product & Engineering Maturity
adequate1% of bug fixes add or change a test
adequateOf 329 fixes in the last 24 months, 2 touched a test. A fix without the test that would have caught the bug can quietly come back, and the suite never learns from what went wrong.

Security & Reliability Posture
strongThe build runs third-party code it does not pin
adequate7 third-party CI actions are referenced by a tag or branch rather than a commit, so they run whatever that tag points to on the day. Tags have been moved to malicious commits in real supply-chain attacks, and a piped script is whatever the server returns that minute. Pinning to a commit is the fix, and it is small.
.github/workflows/cd-sideload-preview.yml:46 — action pinned by tag |
.github/workflows/cd-sideload-preview.yml:48 — action pinned by tag |

adequateThe root licence changed 5 time(s). Code taken under earlier terms stays under them; check which terms any fork or customer relied on.
