Issued 2026-10-23

Reads strong. AGPL-3.0 since 2024-05-21: open source; offering it over a network counts as distributing it, so a hosted product's changes must be published.

105 checks ran across 6 assessable dimensions. 3 of 5 rated dimensions are strong, 2 are adequate and none is significant. Security & Reliability Posture and Product & Engineering Maturity are adequate. 8 findings, each with evidence. One dimension cannot be assessed without an acquirer.

This repository reads strong. Show it in your README: the badge links to a page where anyone can check the reading. If you embed it: link it to the report, remove it if the report is delisted, and do not present it as a certification or an endorsement.

core/wren-core/core/src/mdl/mod.rs is 5,955 lines, 53× this codebase's median file

adequate

The median source file here is 112 lines. 15 files exceed 1,120 lines, the largest being 5,955. 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.

Fixes are 56% of recent work, up from 31%

adequate

In the last two quarters 56% of commits were fixes, against 31% in the quarters before. Rising fix work usually means quality debt is coming due, and it takes time that new work would have had.

Notes that do not affect this rating
04.5

Effort is shifting from building to rewriting

adequate

Deleted lines per line added rose from 0.50 to 1.15 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.

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

Licence text does not match a standard licence

adequate

LICENSE exists but its text does not match any standard licence. A bespoke or hand-edited licence is not wrong, but it cannot be cleared by recognising its name: counsel has to read it, and until they do neither side knows precisely what rights transfer with the code.

Evidence
LICENSE LICENSE:1 — 51 lines, unrecognised

Notes that do not affect this rating
05.27

The build runs third-party code it does not pin

adequate

9 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; 2 steps pipe 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.

10 locked dependencies have published vulnerabilities, 1 high or critical

adequate

10 of 601 locked dependencies match 19 published advisories in OSV, 1 of them rated high or critical. 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. None of the high or critical ones is in what the product ships: they are optional extras of a package, installed only on request. 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.

Evidence
core/wren/uv.lock core/wren/uv.lock — fsspec 2026.1.0: GHSA-27vj-qcqg-25rc (high), fixed in 2026.6.0; an optional extra

Relicensed: Apache-2.0 → AGPL-3.0 (2024-05-21)

adequate

The root licence changed 1 time(s). The latest terms restrict what users, hosts or a buyer may do in ways the earlier ones did not. Code taken under the old terms stays under them, so both matter in diligence.

A note that does not affect this rating: a licence change is a fact for the first screen, and only a narrowing of rights within two years of the surveyed commit costs "strong".

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.

07 · none coverage

Not rated: structurally not assessable from a repository.

  1. This is primarily a Python codebase, with Rust alongside (42% of source files). Does your engineering organisation already run Python in production, or would this be the first? 07.1
  2. The bulk of this system sits in core/, skills/, sdk/. Which of your existing systems would each of those have to absorb or replace? 07.10
  3. 42% of lines added in the last 12 months (17% of added lines) came through AI-declared commits. Does your organisation have a policy on inheriting and maintaining that code, and does your engineering team's tooling match how it was produced? 07.9
  4. 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
  5. 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?
  6. Which of these systems duplicate yours, and which get retired? Answer lives in: Your architecture07.11
  7. What will integration cost, and in what order? Answer lives in: The engagement07.12
  8. Where does the team land in your organisation, and who reports to whom? Answer lives in: Your org design07.13
  9. Are there earn-outs, retention packages or contractor IP to assign? Answer lives in: Deal terms07.14
  10. 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 NOT A CERTIFICATION RQW2-J022-K9A4 2026-10-23 · 86FCCA2 BOREHOLE.DEV/VERIFY

Anyone can check this report against the authoritative record — click the stamp, or enter RQW2-J022-K9A4 at borehole.dev/verify.

The code commits to the 106 checks this run performed, the bands they produced, and the commit they were read at. It does not cover checks written since.

Put the mark in your README

The image is wrapped in a link to the verification page, so a reader can check it rather than take it on trust. If you embed it: link it to the report, remove it if the report is delisted, and do not present it as a certification or an endorsement.

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 — 7 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.

An automated reading of a repository's code and its history up to one commit, with public advisory records. It may be wrong, it is not legal, financial, investment or security advice, and it does not replace diligence by a qualified person. It is provided for information: nobody may rely on it (Borehole's terms, section 3).
