Nothing significant. Questions worth asking about Architecture & Codebase — including AI provenance, Product & Engineering Maturity.

105 checks ran across 6 assessable dimensions. None found a significant problem; 3 raised something worth a question. 12 findings, each with evidence. One dimension cannot be assessed without an acquirer.

internal/xsql/parser.go is 1,899 lines, 16× this codebase's median file

adequate

The median source file here is 118 lines. 5 files exceed 1,180 lines, the largest being 1,899. 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.

111 direct dependencies in a single manifest

adequate

The build runs third-party code it does not pin

adequate

14 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.

12 outbound calls can wait forever

adequate

12 HTTP calls use a client with no timeout (Python `requests` without `timeout=`, or Go's default client). When a dependency slows down, each one holds a worker until the connection gives up, and enough of them take the service down with the dependency.

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

6 SQL statements built from strings

adequate

6 places in product code build SQL by formatting or joining strings rather than passing parameters. 2 of them put a value into the string; in the rest, what the code shows going in is a table or column name, a constant, or something the line does not show. Ask whether any value reaches these strings, rather than a parameter.

05.26

1 locked dependency has published vulnerabilities

adequate

1 of 417 locked dependencies match 1 published advisories in OSV. 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.

10 advisories against this project in the last 24 months, 4 high or critical

adequate

The newest was published on 2026-09-07. 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 5 of them are fixed in the code you ship could not be told from this history: its version is only known to be at least 2.4.0. Answer lives in: the release you run, set against each fixed 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.

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 deployments run a single replica

adequate

1 deployments set `replicas: 1`, and nothing (an autoscaler, a disruption budget) adds more. Every deploy and every node drain is downtime, and the availability the buyer inherits has a ceiling.

Fit with the Acquirer

07 · not assessable · ratings ↑

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.

  1. This is primarily a Go codebase. Does your engineering organisation already run Go in production, or would this be the first? 07.1
  2. The bulk of this system sits in internal/, extensions/, pkg/. Which of your existing systems would each of those have to absorb or replace? 07.10
  3. The repository carries deployment configuration (deploy/docker/Dockerfile and 7 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?

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.

Anyone can check this report against the authoritative record — click the stamp, or enter XK5Q-6XMY-EJ9X 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).
