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

104 checks ran across 6 assessable dimensions. None found a significant problem; 3 raised something worth a question. 13 findings, each with evidence. One dimension cannot be assessed without an acquirer.

pkg/logql/syntax/ast.go is 2,919 lines, 20× this codebase's median file

adequate

The median source file here is 142 lines. 11 files exceed 1,420 lines, the largest being 2,919. 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.

135 direct dependencies in a single manifest

adequate

go.mod declares 135 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.

8 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

The build runs third-party code it does not pin

adequate

3 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. 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.

05.13

4 outbound calls can wait forever

adequate

4 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.

05.9

2 vendored components 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.

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

05.60

Relicensed: Apache-2.0 → AGPL-3.0 (2021-04-20)

adequate

The root licence changed 1 time(s). The latest terms restrict what users, hosts or a buyer may do in ways the earlier ones did not. Code taken under the old terms stays under them, so both matter in diligence.

A note that does not affect this rating: a licence change is a fact for the first screen, and only a narrowing of rights within two years of the surveyed commit costs "strong".

Evidence

4 advisories against this project in the last 24 months, 3 high or critical

adequate

The newest was published on 2026-10-15. 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 4 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 2.1.0. Answer lives in: the release you run, set against each fixed version. The record is incomplete: NVD: 1 record names loki with nothing tying it to this repository (CVE-2005-1943).

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.

Evidence

Readiness and liveness probes are identical in 1 of 2 workloads

adequate

Both probes call the same endpoint. When a dependency slows down, the liveness probe fails with the readiness probe, so the platform restarts pods that only needed taking out of rotation, and a partial outage becomes a full one. Liveness should ask whether the process is alive; readiness whether it can serve.

Evidence
production/helm/loki/values.yaml production/helm/loki/values.yaml — same probe endpoint twice

06.9

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.

06.18

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

adequate

6 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.

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

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.

  2. The bulk of this system sits in vendor/, pkg/, operator/. Which of your existing systems would each of those have to absorb or replace? 07.10
  3. The repository carries deployment configuration (clients/cmd/docker-driver/Dockerfile and 239 more). Does that match your deployment and on-call model, or does it need rehosting first? 07.2

BOREHOLE READING NOT A CERTIFICATION Z7RE-K837-CJ6H 2026-10-22 · BD029BC BOREHOLE.DEV/VERIFY

Anyone can check this report against the authoritative record — click the stamp, or enter Z7RE-K837-CJ6H 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/grafana/loki/bd029bc.svg "Borehole free reading: not for reliance. See the full report.")](https://borehole.dev/verify/Z7REK837CJ6H?via=badge)

Borehole reading Z7RE-K837-CJ6H, not a certification

Quoted evidence

1 piece of evidence on this report quotes the repository directly. Four checks quote text: up to five TODO-style comments, up to four commit subjects, up to five unpinned dependency lines and one status line from the README's first screen, such as “no longer maintained”. In each case the text is the evidence, which is why it is kept by default.

This rewrites every stored reading of this repository, and every later reading, including a re-read, is stored without the quoted text. The facts we keep to re-read it still hold the lines, as the privacy notice says. The pointers stay.

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).
