Nothing significant. Questions worth asking about Architecture & Codebase — including AI provenance, Organization & Key-Person Risk.
92 checks ran across 6 assessable dimensions. 1 finding is worth checking first. 7 findings, each with evidence. One dimension cannot be assessed without an acquirer.
Borehole's proprietary scoring is calibrated across hundreds of repositories. Each finding here reads significant, but its check has not yet held up often enough in that calibration to rate significant on its own. If one holds when someone checks it, it is significant.
- 02.1 Change lands on the trunk with no trace of review
- Words about people are today's: bands rather than exact shares, dates or day counts, and what the history measured rather than why.
- 1 finding rated significant by a check that has not yet held up in Borehole's calibration is now worth checking first.
- 2 findings from checks Borehole's calibration found wrong more often than right are no longer published.

Architecture & Codebase — including AI provenance
01 · adequate · ratings ↑libobs-metal/OBSShader.swift is 1,604 lines, 15× this codebase's median file
adequateThe median source file here is 101 lines. 1 file exceed 1,010 lines, the largest being 1,604. 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.

A move from Objective-C to Swift began 40 months ago and is 50% done
adequate39 product files are in the new language and 39 are still in the old one, 40 months after the first new file appeared. The new language's share of the lines rose from 6% to 42%, and moved 1 percentage points in the last year. Two languages for one job doubles what an engineer has to know, and the unmoved half is usually what nobody wants to touch. Ask whether finishing it is planned, and what it costs.

Engineering Process & SDLC Maturity
02 · adequate · ratings ↑Change lands on the trunk with no trace of review
adequate worth checking firstIn the last 24 months, 23 of 1,232 commits (1.9%) carry any trace of review: a merge, a pull-request reference, a Reviewed-by or Reviewed-on trailer, a Closes/Fixes reference, or a maintainer's sign-off on someone else's change. Every common review workflow leaves at least one of those, so either review happens somewhere this history cannot see, or it is not happening. A buyer should establish which before relying on the review story they are told.
The check that found this reads significant, but it has not yet held up often enough in Borehole's calibration to rate a finding significant on its own. If it holds when someone checks it, this finding is significant.

Organization & Key-Person Risk
03 · adequate · ratings ↑The contributor who wrote a quarter or more of this has not committed here for more than three years
adequateOne person authored a quarter or more of 14,039 commits and has not committed here for more than three years, while the repository has kept moving. The concentration figure alone would not show this. Whoever is changing this code now is not the person who wrote most of it, which is the situation an acquirer is usually told they are avoiding. The history shows only that no commits of theirs landed here, not why.

Security & Reliability Posture

adequateThird-party code is committed into this repository without any statement of the terms it arrived under. Unknown terms are harder to deal with than inconvenient ones: an awkward licence can be complied with, an absent one cannot. Each of these needs its origin established before the code changes hands.

Observability & Operations
06 · strong · ratings ↑No finding. 15 checks ran and none fired; the rejection log below says why each did not.
Fit with the Acquirer
07 · not assessable · ratings ↑Not rated: structurally not assessable from a repository. What a person adds here.
Check it on the running system
2 checks against the running system follow from the findings above: what a buyer's engineer will try, how to run it first, and what to have ready. A paid survey of this repository includes them.
A paid survey of a public repository is also reviewed: a language model reads each finding against the code and withdraws only findings it judges the code contradicts, each listed with its reason. The review is a language model's reading of the findings against the code, and it can be wrong. It never adds a finding, never raises a band, and never removes a finding from a proven check or an advisory that affects the surveyed version.
What a person adds
The survey reads what the repository can show. The code cannot settle these questions, and on them this report states nothing. Each says where its answer lives: your own engineer, the company, or an assessor you choose can settle it. Questions marked measured open with something this repository shows.
Architecture & Codebase — including AI provenance
01 · full coverage- measured No architecture or design document is in the tree, across 4,876 product files. Where does the design live, and who holds it?
- measured The repository pulls code in through git submodules (.gitmodules). A buyer receives pointers, not that code. Can every submodule be fetched without the team's credentials, and who owns each one?
- Is the architecture right for the next three years of the product?
- Were the home-grown components reasonable choices when they were made, and are they now?
Engineering Process & SDLC Maturity
02 · high coverage- Is review real or a rubber stamp? Comment depth and time to approve need the pull request history.
- Is delivery planned and measured, or heroic?
- How are incidents run, reviewed and learned from?
Organization & Key-Person Risk
03 · partial coverage- measured 806 people have committed here. Which of them are you acquiring, and which are you replacing?
- Who mentors whom, and would that survive a departure?
- Can the team grow, and who stands behind the top three contributors?
- Is the seniority mix sound, and will pay survive your salary bands?
- Is the pace sustainable? Commit times cannot say: git keeps no reliable local time.
- Does the team want to stay after close?
- How are decisions made and disagreements resolved?
Product & Engineering Maturity
04 · minimal coverage- Can this team deliver the stated roadmap on the stated timeline?
- Does leadership know about the debt, and is time budgeted to repay it?
- Is the engineering shape consistent with the commercial story?
Security & Reliability Posture
05 · partial coverage- What has actually broken, how often, and how badly?
- What did external testing find, and was it fixed?
- What is the SOC 2, ISO 27001 or GDPR status, and where is the evidence?
Observability & Operations
06 · partial coverage- Are the dashboards opened, the alerts acknowledged and the pages answered?
- Are the service-level objectives actually met?
- Who carries the pager, and how often does it go off?
- What does it cost to run, and how much headroom is there?
Fit with the Acquirer
07 · none coverageNot rated: structurally not assessable from a repository.
- This is primarily a C codebase, with C++ alongside (38% of source files). Does your engineering organisation already run C in production, or would this be the first?
- The bulk of this system sits in frontend/, plugins/, libobs-opengl/. Which of your existing systems would each of those have to absorb or replace?
- Nothing in the repository says how this is deployed. Is it shipped as a library, a binary or a service, and if it runs somewhere, who owns that environment?
- What is your tolerance for the findings above remaining unaddressed for the first two quarters after close, given everything else that will compete for this team's time?
- Which of these systems duplicate yours, and which get retired?
- What will integration cost, and in what order?
- Where does the team land in your organisation, and who reports to whom?
- Are there earn-outs, retention packages or contractor IP to assign?
- Do customer contracts limit hosting, regions or vendors?
A human assessment is Borehole's own paid service, €12,000+ (total price is determined per engagement; travel billed at cost). It is not independent of this report: the same business produced both. It is a separate contract, with its own scope, terms and reliance.
Embed the badge
