getopenscreen/openscreen: technical due diligence, read from its repository
What Borehole read in getopenscreen/openscreen's code and history at 0891c9a: 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.

What the repository says
- Releases are cut from another branch than the one surveyed
Architecture & Codebase — including AI provenance
adequatecrates/compositor/src/frame_geometry.rs is 9,731 lines, 64× this codebase's median file
adequateThe median source file here is 150 lines. 35 files exceed 1,500 lines, the largest being 9,731. 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.

3 model weight files committed directly to git
adequate3 model weight files are stored in git itself, not in LFS, DVC or a model hub. Every clone carries them, the history keeps every version for good, and nothing records which run or data produced them.

Product & Engineering Maturity
strongReleases are cut from another branch than the one surveyed
adequateThe newest release, v2.2.1, is not on the branch this survey read; the newest release on it is v1.9.2. The shipped product may differ from what this report describes. Survey the release branch too.

Security & Reliability Posture
adequateThe build runs third-party code it does not pin
adequate4 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; 4 steps pipe a download straight into a shell. 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/build-whisper-stt.yml:119 — action pinned by tag |
.github/workflows/build.yml:1282 — action pinned by tag |
.github/workflows/aur-publish.yml:136 — download piped into a shell |
46 locked dependencies have published vulnerabilities, 32 high or critical in what ships
adequate46 of 1,827 locked dependencies match 102 published advisories in OSV, 56 of them rated high or critical. A lockfile says which version is installed, not whether the flawed code is reachable from this product, so each needs a look. Most are fixed by an upgrade, and the advisory names the version. This lockfile pins development tools alongside what ships and does not say which is which, so some of these may never reach a user.
website/package-lock.json — proxy-addr 2.0.7: GHSA-jqcg-44mw-7w3h (critical), fixed in 2.0.8; reached only by the build |
website/package-lock.json — shell-quote 1.9.0: GHSA-pqg4-j6r4-53mv (critical), fixed in 1.11.0; reached only by the build |
website/package-lock.json — tinypool 1.1.1: GHSA-5gmw-xhrv-c9v3 (critical), fixed in 2.1.1; reached only by the build |
