Nothing significant. Questions worth asking about Observability & Operations, Engineering Process & SDLC Maturity. People was not rated.

102 checks ran across 6 assessable dimensions. None found a significant problem; 3 raised something worth a question. 10 findings, each with evidence. One dimension cannot be assessed without an acquirer. Last commit 30 October 2026.

Published under today's rules. The verification code attests to this reading as it was stored. This page differs from it as follows.
  • 1 finding from checks Borehole's calibration found wrong more often than right is no longer published.
  • 3 findings about one contributor are withheld: one author wrote nearly all of this repository's commits; a buyer of this report reads them.

crates/duckdb-engine/src/plan/builders.rs is 11,654 lines, 56× this codebase's median file

adequate

The median source file here is 208 lines. 17 files exceed 2,080 lines, the largest being 11,654. 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.

02.1

Little of the recent change carries a trace of review

adequate

In the last 24 months, 158 of 1,779 commits (8.9%) 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.

The build runs third-party code it does not pin

adequate

11 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.

20 locked dependencies have published vulnerabilities, 2 high or critical

adequate

20 of 1,636 locked dependencies match 32 published advisories in OSV, 2 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. 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.

16 places insert HTML from a variable without sanitising it

adequate

16 places set HTML from a value that is neither a literal nor passed through a sanitiser. Where the value can come from a user, that is stored cross-site scripting, and it is the first thing a buyer's security review looks for in a frontend.

7 advisories against this project in the last 24 months, 3 high or critical

adequate

The newest was published on 2026-09-23. A project that publishes advisories is telling its users about its fixes, and the count and pace say how much security work it carries. None of them affects the surveyed version.

A note that does not affect this rating: it describes the project's advisory record, and no advisory in it is known to affect the surveyed commit.

GHSA-6xvv-58mg-4gxx 2026-09-23: GHSA-6xvv-58mg-4gxx (moderate), fixed in 0.7.4: Serve console pipeline id breaks out of an inline onclick handler because HTML-entity escaping is decoded first

No error reporter is wired in

adequate

Nothing in the service initialises an error reporter (Sentry, Rollbar, Bugsnag, Honeybadger or an APM agent). An exception in production reaches a person only if someone is reading the logs, which usually means a customer reports it first.

1 of 1 deployed images carry no version, or `latest`

1 images in the deployment configuration are named without a version or as `latest`. A redeploy can change the software without a commit, a rollback has nothing to roll back to, and nobody can say from the repository what is running.

Not rated: structurally not assessable from a repository. What a person adds here.

Check it on the running system

6 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 Rust codebase, with TypeScript alongside (46% of source files). 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 crates/, frontend/, website/. Which of your existing systems would each of those have to absorb or replace? 07.10
  3. The repository carries deployment configuration (Dockerfile.web and 2 more). Does that match your deployment and on-call model, or does it need rehosting first? 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.

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 BAXN-DZW9-FTCJ 2026-11-03 · 772C19D BOREHOLE.DEV/VERIFY

Anyone can check this report against the authoritative record — click the stamp, or enter BAXN-DZW9-FTCJ 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.

Borehole reading BAXN-DZW9-FTCJ, not a certification

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).
