Nothing significant. Questions worth asking about Engineering Process & SDLC Maturity, Security & Reliability Posture.

101 checks ran across 6 assessable dimensions. None found a significant problem; 2 raised something worth a question. 7 findings, each with evidence. One dimension cannot be assessed without an acquirer.

Published under today's rules. The verification code attests to this reading as it was stored. This page differs from it as follows.
  • 3 findings from checks Borehole's calibration found wrong more often than right are no longer published.

Notes that do not affect this rating
01.3

Commit messages are templated rather than written

adequate

34% of commit subjects are exact repeats of another subject, and subject length varies by only 22.9 characters. A log written by someone explaining their reasoning to a future reader does not look like this. The log is therefore weak evidence of intent, whatever the code is like.

A note that does not affect this rating: in Borehole's calibration, this check's notes were usually true but overstated.

Respond to this finding

Your response is published beside the finding, not instead of it. A finding you can argue with is the point — and a wrong one is calibration data we want.

An owner's response is removed only when it is unlawful, impersonates someone, publishes personal data or a credential, or is not about the finding. Disagreeing with the report is never a reason. To report a response, or to reach us about one, write to takedown@borehole.dev.

src/gfx/vk/__bits/__vk_types.hpp is 4,814 lines, 24× this codebase's median file

adequate

The median source file here is 196 lines. 18 files exceed 1,960 lines, the largest being 4,814. 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 note that does not affect this rating: measured against its own codebase's median, it is below the 85th percentile of 382 surveyed projects' largest files, where this check begins to count.

Engineering Process & SDLC Maturity

02 · adequate · ratings ↑
02.1

Little of the recent change carries a trace of review

adequate

In the last 24 months, 23 of 407 commits (5.7%) carry any trace of review: a merge, a pull-request reference, a Reviewed-by or Reviewed-on trailer, a Closes/Fixes reference, a maintainer's sign-off on someone else's change, or a change applied by someone other than its author. That is low but not absent. Review may happen in a workflow this history does not record; a buyer should ask how change is approved before it ships.

02.5

33% of commit subjects say nothing about the change

adequate

128 of 393 subjects are either under twelve characters or one of the standard placeholders — wip, fix, update. The history is therefore not usable for reconstructing why a decision was taken, which is the main thing an inheriting engineer needs it for. It says nothing about code quality and a great deal about how much context transfers with the asset.

24% of recent commits change more than 2,000 lines

adequate

88 of 368 commits in the last 24 months changed over 2,000 lines of code, not counting reformatting, renames, vendored or generated code. A change that size is rarely reviewed line by line. Ask how they were reviewed, and what made them that large.

A note that does not affect this rating
02.6

Almost no process scaffolding exists in the repository

adequate

Of five ordinary markers — CI workflows, CODEOWNERS, a pull-request template, pre-commit hooks, contribution guidance — 1 is present: contribution guidance. 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.

A note that does not affect this rating: in Borehole's calibration, this check's notes were usually true but overstated.

Organization & Key-Person Risk

03 · not assessable · ratings ↑

Not rated: this repository belongs to a person rather than an organisation, so a finding about one contributor would be about someone the address names; the public report does not carry those, and does not rate this dimension without them. What a person adds here.

05.2

None of the standard security guard rails are configured

adequate

There 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.

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. See the tiers.

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.

07 · none coverage

Not rated: structurally not assessable from a repository.

  1. This is primarily a C++ codebase. Does your engineering organisation already run C++ in production, or would this be the first? 07.1
  2. The bulk of this system sits in src/, benches/, external/. Which of your existing systems would each of those have to absorb or replace? 07.10
  3. 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? 07.2
  4. 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?
  5. Which of these systems duplicate yours, and which get retired? Answer lives in: Your architecture07.11
  6. What will integration cost, and in what order? Answer lives in: The engagement07.12
  7. Where does the team land in your organisation, and who reports to whom? Answer lives in: Your org design07.13
  8. Are there earn-outs, retention packages or contractor IP to assign? Answer lives in: Deal terms07.14
  9. Do customer contracts limit hosting, regions or vendors? Answer lives in: Customer contracts07.15

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

Tied to this commit and this date, and it fades after 90 days — an honest badge is one that expires. A repository with significant findings gets a neutral "read" badge rather than a red one: the library is where the range is visible, not someone else's README.

Borehole reading AX2M-7VFK-4CPD, not a certification

Quoted evidence

4 pieces of evidence on this report quote the repository directly. Four checks quote text: up to five TODO-style comments, up to four commit subjects, up to five unpinned dependency lines and one status line from the README's first screen, such as “no longer maintained”. In each case the text is the evidence, which is why it is kept by default.

This rewrites every stored reading of this repository, and every later reading, including a re-read, is stored without the quoted text. The facts we keep to re-read it still hold the lines, as the privacy notice says. The pointers stay.

Where this scan ran

This scan ran on ordinary cloud infrastructure (cloud-run), not in a hardware-isolated confidential VM. Nothing about it is attested by Google.

What an attested survey proves, and what it does not.

What this scan did with the repository — 8 steps

Written by the steps themselves as they ran, not described afterwards. A hand-written account of a data flow drifts the first time somebody changes the flow and not the account.
