Nothing significant. Questions worth asking about Security & Reliability Posture, Architecture & Codebase — including AI provenance.

104 checks ran across 6 assessable dimensions. None found a significant problem; 4 raised something worth a question. 10 findings, each with evidence. One dimension cannot be assessed without an acquirer.

What the repository says about itself
An earlier reading. This is the survey of 2026-10-03 by borehole 0.7.11, which is what its verification code attests to. A newer reading of the same commit exists: read the newest.

1 base image floats: no version, or `latest`

adequate

1 of 2 `FROM` lines in product Dockerfiles name an image without a version, or with `latest`. Each build pulls whatever the registry serves that day, so the image that ships can change without a commit, and last month's build cannot be reproduced. Pin a version, or a digest.

Evidence
Dockerfile Dockerfile:1 — base image without a version

crates/ty_python_semantic/src/types/infer/builder.rs is 13,223 lines, 264× this codebase's median file

adequate

The median source file here is 50 lines. 173 files exceed 1,000 lines, the largest being 13,223. 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. Measured against its own codebase's median, it is larger than 94% of 382 surveyed projects' largest files.

CI runs tests that cannot fail the build

1 test command in CI ends in `|| true` or an equivalent, so the pipeline passes whatever the tests say. A green build then means the tests ran, not that they passed.

5 files still carry code deprecated more than two years ago

adequate

5 files were marked deprecated over two years ago and still are, the oldest since Jul 2023. A deprecation is a promise to remove. Ask what still depends on these, and whether removing them is scheduled.

1 Dockerfile runs the application as root

adequate

No USER instruction switches away from root, so the process runs with full privileges inside the container. It is a one-line fix and an ordinary expectation, which is why its absence is worth asking about: it usually says more about whether anyone has reviewed the deployment than about this container specifically.

Evidence
no-USER-instruction Dockerfile — runs as root

The build runs third-party code it does not pin

adequate

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.

05.26

6 locked dependencies have published vulnerabilities, 4 high or critical

adequate

6 of 787 locked dependencies match 10 published advisories in OSV, 4 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 development dependencies. 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
uv.lock uv.lock — anyio 4.14.1: GHSA-82r6-8w77-94w6 (critical), fixed in 4.14.2; a development dependency

1 vendored component with no licence

adequate

Third-party code is committed into this repository without any statement of the terms it arrived under. Unknown terms are harder to deal with than inconvenient ones: an awkward licence can be complied with, an absent one cannot. Each of these needs its origin established before the code changes hands.

One request cannot be followed through the logs

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.

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

Check it on the running system

7 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.

Not rated: structurally not assessable from a repository.

  3. The repository carries deployment configuration (Dockerfile). Does that match your deployment and on-call model, or does it need rehosting first? 07.2

  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.

BOREHOLE READING NOT A CERTIFICATION XVX9-BSWK-7QE4 2026-10-03 · 7D73E4B BOREHOLE.DEV/VERIFY

Anyone can check this report against the authoritative record — click the stamp, or enter XVX9-BSWK-7QE4 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, not a certification](https://borehole.dev/badge/astral-sh/ruff/7d73e4b.svg "Borehole free reading: not for reliance. See the full report.")](https://borehole.dev/verify/XVX9BSWK7QE4?via=badge)

Borehole reading XVX9-BSWK-7QE4, not a certification

This commit has been surveyed 9 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.

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).
