Nothing significant. Questions worth asking about Security & Reliability Posture, Observability & Operations.

100 checks ran across 6 assessable dimensions. None found a significant problem; 5 raised something worth a question. 15 findings, each with evidence. One dimension cannot be assessed without an acquirer.

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

adequate

1 of 70 `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.

lib/onigmo/enc/unicode/name2ctype.h is 45,682 lines, 343× this codebase's median file

adequate

The median source file here is 133 lines. 318 files exceed 1,330 lines, the largest being 45,682. 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 97% of 382 surveyed projects' largest files.

Bus factor 1: one account applies recent work

adequate

In the last 24 months, one account applied or wrote more than half of 3,545 non-merge commits, most of them written by others, among 152 authors; across all history, one contributor authored a quarter or more of 14,038. Every change passes through that one account, however many people write them. In a project with 152 recent contributors and 13 years of history, that is a question about one person's role rather than a fragile team — but it is the question to ask.

Evidence

Ruby 3.2 is past end of life

adequate

The code is pinned to Ruby 3.2 (end of life 2026-03-31). None of these receives security fixes any more; the first stopped on 2026-03-31. Moving off an unsupported runtime is rarely a one-line change, so a buyer should ask whether the upgrade is planned and what it touches.

11 Dockerfiles run 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.

8 advisories against this project in the last 24 months, 6 high or critical

adequate

The newest was published on 2026-09-08. A project that publishes advisories is telling its users about its fixes, and the count and pace say how much security work it carries. The record is incomplete: NVD: 1 record names fluent-bit with nothing tying it to this repository (CVE-2025-12978).

The build runs third-party code it does not pin

adequate

21 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.

2 shell commands built from strings

adequate

2 places run a command through a shell (`shell=True`, `os.system`, `exec` with a template) rather than passing arguments. Where any part comes from outside, it is command injection. Ask where each one's input comes from.

05.26

2 locked dependencies have published vulnerabilities, 1 high or critical

adequate

2 of 11 locked dependencies match 5 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. This lockfile pins development tools alongside what ships and does not say which is which, so some of these may never reach a user.

No structured logging library is in use

adequate

Nothing references a structured logging library. Logs that are written to be read by a person are not searchable by a machine, which means incident response here is proportional to how well someone remembers the codebase rather than to what the tooling can find.

Evidence
logging-scan C source is not searched: C programs log through printf-style calls unless they take a library, and none of the 10 searched for is referenced

06.8

One request cannot be followed through the logs

Nothing in the service carries a request or correlation id, and there is no tracing. When a customer reports a failure, the log lines that belong to their request cannot be picked out from everyone else's.

No error reporter is wired in

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.

3 of 5 deployed images carry no version, or `latest`

3 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

8 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.

BOREHOLE READING NOT A CERTIFICATION CWT9-GEK8-K4P3 2026-10-28 · F68B7B1 BOREHOLE.DEV/VERIFY

Anyone can check this report against the authoritative record — click the stamp, or enter CWT9-GEK8-K4P3 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).
