Nothing significant. Questions worth asking about Organization & Key-Person Risk, Observability & Operations.

105 checks ran across 6 assessable dimensions. None found a significant problem; 3 raised something worth a question. 10 findings, each with evidence. One dimension cannot be assessed without an acquirer.

What the repository says about itself
What this survey read. This commit may not be the product users run: The newest pre-release, v2.15.1-RC.1, is not on the branch this survey read; the newest release on it is v2.15.0. Read this report as describing that commit, not the release users run. Survey the release branch or tag as well.
Published under today's rules. The verification code attests to this reading as it was stored. This page differs from it as follows.
  • 1 finding from checks Borehole's calibration found wrong more often than right is no longer published.
  • The file and line of 3 credential-shaped matches are withheld. File and line are shown to whoever GitHub says controls this repository, signed in, and to a buyer of this report.

server/filestore.go is 14,733 lines, 46× this codebase's median file

adequate

The median source file here is 317 lines. 17 files exceed 3,170 lines, the largest being 14,733. 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.

03.1

Bus factor 1: recent work is concentrated in one contributor

adequate

In the last 24 months, one contributor authored more than half of 2,206 non-merge commits among 90 authors; across all history, a quarter or more of 8,490. In a project with 90 recent contributors and 14 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

03.5

The contributor who wrote a quarter or more of this has not committed here for more than a year

adequate

One person authored a quarter or more of 8,490 commits and has not committed here for more than a year, while the repository has kept moving. The concentration figure alone would not show this. Whoever is changing this code now is not the person who wrote most of it, which is the situation an acquirer is usually told they are avoiding. The history shows only that no commits of theirs landed here, not why.

03.12

The next contributor after the top one has not committed here for more than a year

adequate

The #2 contributor of the last three years (less than a quarter of the commits) has not committed here for more than a year, while the repository is still active. These are the people a buyer assumes would step up if the top contributor stopped. The history shows only that no commits of theirs landed here, not why.

05.1

3 credential-shaped strings committed to the tree

adequate

Matches for JWT appear in tracked files outside test and fixture paths. They stay in the history even after they leave the tree, so what matters is whether each was rotated. The code cannot tell whether any of them is live, and that decides whether this matters: none sits in production configuration, and none is in a format its provider keeps for live keys. Is any of these live? Show that each was rotated after it was committed, and when.

Evidence
JWT 3 cited: JWT pattern matched

28 advisories against this project in the last 24 months, 13 high or critical

adequate

The newest was published on 2026-06-29. 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 1 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 2.15.0. Answer lives in: the release you run, set against each fixed version. The record is incomplete: NVD: 1 record names nats-server with nothing tying it to this repository (CVE-2021-3127).

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.

Observability & Operations

06 · adequate · ratings ↑
06.1

No telemetry or error reporting is wired in anywhere

adequate

None of 421 readable files references an instrumentation, metrics or error-reporting library. If this system is in production, nobody learns that it broke from the system itself — they learn it from a customer. That is a reliability finding before it is an observability one.

Evidence
telemetry-scan searched 421 tracked text files for 16 known instrumentation libraries; manifests for metrics, tracing and error-reporting families; locked dependencies for the packages that emit; 0 matched

06.2

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

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.

A note that does not affect this rating: notes like it are common in well-run projects.

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.

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

BOREHOLE READING NOT A CERTIFICATION Q8FY-ESS9-4MVG 2026-10-04 · 60B9679 BOREHOLE.DEV/VERIFY

Anyone can check this report against the authoritative record — click the stamp, or enter Q8FY-ESS9-4MVG 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/nats-io/nats-server/60b9679.svg "Borehole free reading: not for reliance. See the full report.")](https://borehole.dev/verify/Q8FYESS94MVG?via=badge)

Borehole reading Q8FY-ESS9-4MVG, not a certification

This commit has been surveyed 8 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 — 3 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).
