Nothing significant. Questions worth asking about Security & Reliability Posture, Product & Engineering Maturity.

105 checks ran across 6 assessable dimensions. 1 finding is worth checking first. 13 findings, each with evidence. One dimension cannot be assessed without an acquirer.

What the repository says about itself
Worth checking first

Borehole's proprietary scoring is calibrated across hundreds of repositories. Each finding here reads significant, but its check has not yet held up often enough in that calibration to rate significant on its own. If one holds when someone checks it, it is significant.

pkg/ingester/ingester.go is 4,088 lines, 32× this codebase's median file

adequate

The median source file here is 126 lines. 9 files exceed 1,260 lines, the largest being 4,088. 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.

87 direct dependencies in a single manifest

go.mod declares 87 direct dependencies. Each one is a maintenance obligation, a supply-chain surface and a potential licence question that transfers with the asset. The count says nothing about whether any given dependency was a good choice; it says how many such choices a buyer inherits.

API v1 and v2 have been served together for 34 months

7 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.

Evidence

05.26

8 locked dependencies have published vulnerabilities, 3 high or critical in what ships

adequate worth checking first

8 of 350 locked dependencies match 13 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. This lockfile pins development tools alongside what ships and does not say which is which, so some of these may never reach a user.

The check that found this reads significant, but it has not yet held up often enough in Borehole's calibration to rate a finding significant on its own. Opening go.mod settles it. If it holds when someone checks it, this finding is significant.

Evidence
go.mod go.mod — github.com/prometheus/prometheus v0.309.1: GHSA-8rm2-7qqf-34qm (high), fixed in 0.311.3
go.mod go.mod — go.etcd.io/etcd/client/pkg/v3 v3.5.17: GO-2026-6107 (high), fixed in 3.5.33

5 workload settings can give a container the host, behind a chart value or in a stack built from source

adequate

5 places run a container privileged or in the host's namespaces only when a Helm value switches them on, or in a compose file that builds the product from this repository, which is how it is developed rather than how it ships. Neither is on by default in what ships. Ask whether production sets the value or runs that stack.

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.

3 outbound calls can wait forever

adequate

3 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.

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.

2 of 10 deployed images carry no version, or `latest`

2 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.

01.burst_import the largest burst was a branch merged by a merge commit, developed on its own branch and landed in one piece (100% of it), which explains the rate: translations arrive from a vendor in bulk, dependencies and generated code are committed whole, a merged pull request is dated when it merged, not when it was written, a branch merged by a merge commit was reviewed as one piece, and an export or mirror tool dates history when it replays itlargest commits 59f0c02..d4f1c5a · bursts explained 1 · largest net added 4,659

BOREHOLE READING NOT A CERTIFICATION F079-FG3D-JKP4 2026-11-03 · 23B90B8 BOREHOLE.DEV/VERIFY

Anyone can check this report against the authoritative record — click the stamp, or enter F079-FG3D-JKP4 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).
