Nothing significant. Questions worth asking about Security & Reliability Posture, Observability & Operations.

103 checks ran across 6 assessable dimensions. 2 findings are worth checking first. 15 findings, each with evidence. One dimension cannot be assessed without an acquirer.

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.

client/src/Pages/Settings/index.tsx is 1,205 lines, 16× this codebase's median file

adequate

The median source file here is 73 lines. 2 files exceed 1,000 lines, the largest being 1,205. 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.

Bus factor 1: recent work is concentrated in one contributor

adequate

In the last 24 months, one contributor authored more than half of 5,289 non-merge commits among 168 authors; across all history, more than half of 7,082. This is the single most expensive thing to discover after closing, and the repository cannot tell you whether that person is part of the transaction.

04.5

Effort is shifting from building to rewriting

adequate

Deleted lines per line added rose from 0.67 to 0.91 between the first and second halves of this history. Rework is normal and often healthy, but a rising ratio means an increasing share of the team's time is spent replacing code that already exists rather than building what does not. Whether that is deliberate repayment or churn is a question for the team.

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

33 locked dependencies have published vulnerabilities, 48 high or critical in what ships

adequate worth checking first

33 of 902 locked dependencies match 126 published advisories in OSV, 57 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.

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 server/package-lock.json and the 1 other file it cites settles it. If it holds when someone checks it, this finding is significant.

Manifest says ISC, licence file says AGPL-3.0

adequate worth checking first

package.json declares ISC. LICENSE contains the text of AGPL-3.0. Package managers and downstream users read the first; auditors and acquirers read the second. One of them is wrong, and until it is settled the terms this code is offered under are genuinely ambiguous.

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 package.json:19 and the 1 other file it cites settles it. If it holds when someone checks it, this finding is significant.

1 environment file is committed

adequate

client/.env.production is tracked in git. Environment files are where credentials usually live, and committing one usually means nobody decided how secrets reach the running application. Whatever is in it is in the history for good. Check 05.1 says whether it holds anything credential-shaped.

05.27

The build runs third-party code it does not pin

adequate

6 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.

4 of 4 Kubernetes workloads declare no resource limits

4 workload manifests set no CPU or memory limits. One pod that leaks memory or spins can starve everything else on its node, and the scheduler cannot plan capacity for what it cannot see.

9 advisories against this project in the last 24 months, 6 high or critical

adequate

The newest was published on 2026-09-03. 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 3.13.1. Answer lives in: the release you run, set against each fixed version. The record is incomplete: NVD: 1 record names checkmate with nothing tying it to this repository (CVE-2026-36102).

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 851 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 851 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

06.14

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
charts/helm/checkmate/templates/api/deployment.yaml charts/helm/checkmate/templates/api/deployment.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.

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

06.18

3 of 3 deployed images carry no version, or `latest`

3 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

11 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 0ecc2e2..a864bc0 · bursts explained 1 · largest net added 4,027

BOREHOLE READING NOT A CERTIFICATION RCTB-FF9H-CRGK 2026-10-28 · 47BDE88 BOREHOLE.DEV/VERIFY

Anyone can check this report against the authoritative record — click the stamp, or enter RCTB-FF9H-CRGK 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 RCTB-FF9H-CRGK, not a certification

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).
