doitsujin/dxvk: technical due diligence, read from its repository
What Borehole read in doitsujin/dxvk's code and history at 02e2028: 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

Architecture & Codebase — including AI provenance
strongsrc/dxvk/dxvk_context.cpp is 11,004 lines, 80× this codebase's median file
adequateThe median source file here is 136 lines. 23 files exceed 1,360 lines, the largest being 11,004. 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.
src/dxvk/dxvk_context.cpp:1 — 11,004 lines (80× median) |
src/d3d9/d3d9_device.cpp:1 — 9,269 lines (68× median) |
src/d3d11/d3d11_context.cpp:1 — 6,095 lines (44× median) |

Engineering Process & SDLC Maturity
adequateTests are absent or token
adequate0 test files against 531 source files (0.0%). 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.
| 0 test files / 531 source files |
Almost no process scaffolding exists in the repository
adequateOf five ordinary markers — CI workflows, CODEOWNERS, a pull-request template, pre-commit hooks, contribution guidance — 1 is present: CI workflows. Branch protection itself is a GitHub setting rather than a file, so this is a reading of proxies and not of the rules themselves. What it does establish is that the process is not written down anywhere a new engineer would find it.
| 1 of 5 markers present across 591 tracked files |
Product & Engineering Maturity
not assessableEffort is shifting from building to rewriting
adequateDeleted lines per line added rose from 0.32 to 0.84 between the first and second halves of this history. Rework is normal and often healthy, but a rising ratio means an increasing share of the team's time is spent replacing code that already exists rather than building what does not. Whether that is deliberate repayment or churn is a question for the team.
| first half 0.32, second half 0.84 (split 2022-04-16) |
Security & Reliability Posture
adequateNone of the standard security guard rails are configured
adequateThere is no disclosure policy, no automated dependency updates, no named code owners and no pre-commit configuration. None of these is load-bearing on its own. Their collective absence says that security posture here is whatever the current team happens to remember to do, which is not a posture that survives the team changing.
| checked 5 kinds of guard rail across 591 tracked files; 0 present |
Observability & Operations
not assessableNot rated: only 4 of 16 checks could reach a conclusion here; the rest do not apply to this repository or could not read it.
Fit with the Acquirer
not assessableNot rated: structurally not assessable from a repository.
