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.

05.26 27 locked dependencies have published vulnerabilities, 2 high or critical in what ships

0% of added lines arrived in commits declaring an AI agent as co-author

The surviving-lines measurement was not run on this repository.

1% of lines added in the last 12 months (since 2025-10-23) arrived in AI-declared commits: 3/601 commits, confidence low. Also a floor.

confidence: low

2% of non-merge commits carry any trailer at all
low trailer coverage: the convention may not be in consistent use
32% of commits show author/committer date divergence, which is the shape of replayed history that can drop trailers

43,110 lines excluded as lockfiles, vendored or generated.

This is a lower bound. It counts what the repository declares. Undeclared AI authorship is invisible here, and a single rebase removes the trailers this rests on. Absence of a declaration is absence of disclosure, not absence of AI authorship.

1 base image floats: no version, or `latest`

adequate

1 of 2 `FROM` lines in product Dockerfiles name an image without a version, or with `latest`. Each build pulls whatever the registry serves that day, so the image that ships can change without a commit, and last month's build cannot be reproduced. Pin a version, or a digest.

Evidence

01.3

Commit messages are templated rather than written

adequate

42% of commit subjects are exact repeats of another subject, and subject length varies by only 17.8 characters. A log written by someone explaining their reasoning to a future reader does not look like this. The log is therefore weak evidence of intent, whatever the code is like.

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

agent/src/config/handler.rs is 6,250 lines, 71× this codebase's median file

adequate

The median source file here is 87 lines. 78 files exceed 1,000 lines, the largest being 6,250. 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.

Almost no process scaffolding exists in the repository

adequate

Of five ordinary markers — CI workflows, CODEOWNERS, a pull-request template, pre-commit hooks, contribution guidance — 1 is present: CI workflows. Branch protection itself is a GitHub setting rather than a file, so this is a reading of proxies and not of the rules themselves. What it does establish is that the process is not written down anywhere a new engineer would find it.

106 direct dependencies in a single manifest

adequate

server/go.mod declares 106 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 52 months

v2 first appeared in Jun 2022, and v1 is still in the code 52 months later. Two versions mean two surfaces to secure, document and support. Ask who still calls the old one, and whether retiring it is planned.

Evidence

Go 1.21 is past end of life

adequate

The code is pinned to Go 1.21 (end of life 2024-08-13). None of these receives security fixes any more; the first stopped on 2024-08-13. Moving off an unsupported runtime is rarely a one-line change, so a buyer should ask whether the upgrade is planned and what it touches.

05.2

None of the standard security guard rails are configured

adequate

There is no disclosure policy, no automated dependency updates, no named code owners and no pre-commit configuration. None of these is load-bearing on its own. Their collective absence says that security posture here is whatever the current team happens to remember to do, which is not a posture that survives the team changing.

05.6

2 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.

05.26

27 locked dependencies have published vulnerabilities, 2 high or critical in what ships

adequate worth checking first

27 of 862 locked dependencies match 47 published advisories in OSV, 6 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 cli/go.mod and the 2 other files it cites settles it. If it holds when someone checks it, this finding is significant.

Evidence

5 workload settings give a container the host

adequate worth checking first

5 places in the deployment configuration run a container privileged or in the host's network, process or IPC namespace. A compromise of that container is a compromise of the machine, and most acquirers' security reviews block it. Node agents (network, storage, monitoring) are excluded.

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 agent/docker/deepflow-agent-ds.yaml:20 and the 1 other file it cites settles it. If it holds when someone checks it, this finding is significant.

Evidence

agent/docker/deepflow-agent-ds.yaml	`agent/docker/deepflow-agent-ds.yaml:20` — privileged or host namespace
agent/docker/deepflow-agent-ds.yaml	`agent/docker/deepflow-agent-ds.yaml:26` — privileged or host namespace

05.25

1 environment file is committed

adequate

manifests/deepflow-docker-compose/.env 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

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; 10 steps pipe 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.

7 outbound calls can wait forever

adequate

7 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.

1 SQL statement built from strings

adequate

1 places in product code build SQL by formatting or joining strings rather than passing parameters. In each, what the code shows going in is a table or column name, a constant, or something the line does not show, not a request's value. Ask whether any value reaches these strings, rather than a parameter.

2 of 2 Kubernetes workloads declare no resource limits

Not rated: structurally not assessable from a repository. What a person adds here.

Check it on the running system

12 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.

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).
