Nothing significant. Questions worth asking about Engineering Process & SDLC Maturity, Product & Engineering Maturity.

103 checks ran across 6 assessable dimensions. 1 finding is worth checking first. 5 findings, each with evidence. One dimension cannot be assessed without an acquirer.

What the repository says about itself
Worth checking first

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.

Tests cover a thin slice of the codebase

adequate worth checking first

32 test files against 1,350 source files (2.4%). 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.

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.

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.

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. The findings below are what it could still read.

Regular contributors fell from 7 to 2 in a year

5 people who committed regularly the year before made no commits in the last year, and 1 new regular contributors arrived. Ask whether the work they did is still covered.

Notes that do not affect this rating
05.27

The build runs third-party code it does not pin

adequate

15 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; 1 step pipes 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.

A note that does not affect this rating: notes like it are common in well-run projects.

3 locked dependencies have published vulnerabilities

adequate

3 of 548 locked dependencies match 3 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.

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

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. 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

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 yazi-core/, yazi-plugin/, yazi-shared/. 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.

This commit has been surveyed 6 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.

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

What this scan did with the repository — 4 steps
