Reads strong: 3 of 5 rated dimensions are strong, 2 are adequate and none is significant.

93 checks ran across 6 assessable dimensions. Security & Reliability Posture and Architecture & Codebase — including AI provenance are adequate. 3 findings, each with evidence. One dimension cannot be assessed without an acquirer.

An earlier reading. This is the survey of 2026-09-26 by borehole 0.6.2, which is what its verification code attests to. A newer reading of the same commit exists: read the newest.
Published under today's rules. The verification code attests to this reading as it was stored. This page differs from it as follows.

  • 18% of non-merge commits carry any trailer at all
  • low trailer coverage: the convention may not be in consistent use
  • 29% of commits show author/committer date divergence, which is the shape of replayed history that can drop trailers

This is a lower bound. It counts what the repository declares. Undeclared AI authorship is invisible here, and a single rebase removes the trailers this rests on. Absence of a declaration is absence of disclosure, not absence of AI authorship.

src/vscreen.rs is 1,170 lines, 12× this codebase's median file

adequate

The median source file here is 92 lines. 2 files exceed 1,000 lines, the largest being 1,170. 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.

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.

20 dependencies float, and no lockfile is committed

adequate

Dependency versions are declared as ranges and no lockfile is committed, so a build today does not necessarily produce what a build last month produced. That matters twice over in a transaction: the thing being bought cannot be reproduced exactly, and a compromised upstream release arrives without anyone choosing to take it.

4 locked dependencies have published vulnerabilities

adequate

4 of 317 locked dependencies match 4 published advisories in OSV. 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.

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. 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.

Architecture & Codebase — including AI provenance

01 · full coverage
  1. measured No architecture or design document is in the tree, across 298 product files. Where does the design live, and who holds it? Answer lives in: The team01.38
  2. 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? Answer lives in: The team and the submodule owners01.35
  3. Is the architecture right for the next three years of the product? Answer lives in: Your architects, with the product roadmap01.39
  4. Were the home-grown components reasonable choices when they were made, and are they now? Answer lives in: The team's reasoning at the time01.40

Engineering Process & SDLC Maturity

02 · high coverage
  1. Is review real or a rubber stamp? Comment depth and time to approve need the pull request history. Answer lives in: The code host's pull request data02.32
  2. Is delivery planned and measured, or heroic? Answer lives in: The issue tracker: backlog, sprint history, estimate accuracy02.38
  3. How are incidents run, reviewed and learned from? Answer lives in: Tickets, chat and postmortems02.37

Organization & Key-Person Risk

03 · partial coverage

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.

  1. Which of them are you acquiring, and which are you replacing? Answer lives in: The deal terms03.29
  2. Who mentors whom, and would that survive a departure? Answer lives in: The team; review history only suggests candidates03.28
  3. Can the team grow, and who stands behind the top three contributors? Answer lives in: Recruiting data and the org chart03.30
  4. Is the seniority mix sound, and will pay survive your salary bands? Answer lives in: HR data03.31
  5. Is the pace sustainable? Commit times cannot say: git keeps no reliable local time. Answer lives in: Interviews and on-call history03.14
  6. Does the team want to stay after close? Answer lives in: Interviews03.32
  7. How are decisions made and disagreements resolved? Answer lives in: Time with the team03.33

Product & Engineering Maturity

04 · minimal coverage
  1. Can this team deliver the stated roadmap on the stated timeline? Answer lives in: The data room and the team's record of estimates04.32
  2. Does leadership know about the debt, and is time budgeted to repay it? Answer lives in: Budget and roadmap decisions04.31
  3. Is the engineering shape consistent with the commercial story? Answer lives in: Revenue, customer and churn data04.33

Security & Reliability Posture

05 · partial coverage
  1. What has actually broken, how often, and how badly? Answer lives in: Ticketing and chat05.41
  2. What did external testing find, and was it fixed? Answer lives in: Reports in the data room05.42
  3. What is the SOC 2, ISO 27001 or GDPR status, and where is the evidence? Answer lives in: Audit reports; policy files in the tree are not evidence05.44

Observability & Operations

06 · partial coverage
  1. Are the dashboards opened, the alerts acknowledged and the pages answered? Answer lives in: Pager history and dashboard logs06.29
  2. Are the service-level objectives actually met? Answer lives in: Production metrics06.30
  3. Who carries the pager, and how often does it go off? Answer lives in: Pager exports and interviews06.31
  4. What does it cost to run, and how much headroom is there? Answer lives in: Cloud billing and capacity plans06.32

Fit with the Acquirer

07 · none coverage

Not rated: structurally not assessable from a repository.

  1. This is primarily a Rust codebase. Does your engineering organisation already run Rust in production, or would this be the first? 07.1
  2. The bulk of this system sits in assets/, src/, build/. 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 B5TV-P8B8-1S54, not a certification

Quoted evidence

5 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.

This commit has been surveyed 16 times

A survey is a reading by a particular version of the assessor. Older readings are kept rather than replaced, because a verification mark attests to the survey it was issued for — overwriting one would make every code already in circulation read as tampered.

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.
