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

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

What the repository says about itself
  • 04.62 Releases are cut from another branch than the one surveyed
Degraded run. History truncated at 50,000 commits, the most a hosted survey reads. Signals needing the full history are reported as inconclusive rather than clean.
What this survey read. This commit may not be the product users run: The newest release, v7.2.4, is not on the branch this survey read; the newest release on it is v8.1.0.beta1. Read this report as describing that commit, not the release users run. Survey the release branch or tag as well.
An earlier reading. This is the survey of 2026-09-29 by borehole 0.7.6, which is what its verification code attests to. A newer reading of the same commit exists: read the newest.

This is a lower bound. It counts what the repository declares. Undeclared AI authorship is invisible here, and a single rebase removes the trailers this rests on. Absence of a declaration is absence of disclosure, not absence of AI authorship.

guides/assets/javascripts/@hotwired--turbo.js is 3,939 lines, 62× this codebase's median file

adequate

The median source file here is 63 lines. 27 files exceed 1,000 lines, the largest being 3,939. 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.

Releases are cut from another branch than the one surveyed

adequate

The newest release, v7.2.4, is not on the branch this survey read; the newest release on it is v8.1.0.beta1. The shipped product may differ from what this report describes. Survey the release branch too. This was read from the most recent 50,000 commits (5 Dec 2014 to 25 Sep 2026) only; older history was not read.

12 deserialisers that can run code

adequate

12 places read data with a deserialiser that executes what it reads (pickle, `yaml.load` without a safe loader, object streams, `unserialize`). That is safe on data the system wrote itself and remote code execution on anything else. Ask where each one's input comes from.

43 locked dependencies have published vulnerabilities, 41 high or critical

adequate

43 of 981 locked dependencies match 130 published advisories in OSV, 41 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.

Evidence
Gemfile.lock Gemfile.lock — rack-session 2.1.1: GHSA-33qg-7wpp-89cq (critical), fixed in 2.1.2
Gemfile.lock Gemfile.lock — addressable 2.8.7: GHSA-h27x-rffw-24p4 (high), fixed in 2.9.0

05.65

18 advisories against this project in the last 24 months, 2 high or critical

adequate

The newest was published on 2026-07-29. A project that publishes advisories is telling its users about its fixes, and the count and pace say how much security work it carries. Whether 18 of them are fixed in the code you ship could not be told from this history. Answer lives in: the release you run, set against each fixed version.

Evidence
GHSA-xr9x-r78c-5hrm 2026-07-29: GHSA-xr9x-r78c-5hrm (critical), fixed in 7.2.3.2: Possible arbitrary file read and remote code execution in Active Storage variant processing

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

3 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 Ruby codebase. Does your engineering organisation already run Ruby in production, or would this be the first? 07.1
  2. The bulk of this system sits in activerecord/, guides/, activesupport/. Which of your existing systems would each of those have to absorb or replace? 07.10
  3. The repository carries deployment configuration (railties/lib/rails/generators/rails/app/templates/Dockerfile.tt). 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.

BOREHOLE READING NOT A CERTIFICATION QMYJ-R7SC-NAT9 2026-09-29 · 7D52E01 BOREHOLE.DEV/VERIFY

Anyone can check this report against the authoritative record — click the stamp, or enter QMYJ-R7SC-NAT9 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/rails/rails/7d52e01.svg "Borehole free reading: not for reliance. See the full report.")](https://borehole.dev/verify/QMYJR7SCNAT9?via=badge)

Borehole reading QMYJ-R7SC-NAT9, not a certification

This commit has been surveyed 17 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).
