Nothing significant. Questions worth asking about Security & Reliability Posture, Architecture & Codebase — including AI provenance.

104 checks ran across 6 assessable dimensions. 1 finding is worth checking first. 12 findings, each with evidence. One dimension cannot be assessed without an acquirer.

What the repository says about itself
  • 6 submodule(s) this survey does not read: packages/leann-backend-diskann/third_party/DiskANN, packages/leann-backend-hnsw/third_party/faiss, packages/leann-backend-hnsw/third_party/msgpack-c .gitmodules:1
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 28 locked dependencies have published vulnerabilities, 47 high or critical in what ships
What this survey read. This commit may not be the product users run: the product's code is in submodules this survey did not read (packages/leann-backend-diskann/third_party/DiskANN/, packages/leann-backend-hnsw/third_party/faiss/, packages/leann-backend-hnsw/third_party/msgpack-c/), beside 92 source files of its own. No dimension is rated strong: most of the product was not read. Survey the submodules' repositories 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.

  • low trailer coverage: the convention may not be in consistent use
  • no widespread author/committer date divergence

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.

The repository begins with most of itself already written

adequate

The first commit carries 278,432 lines — 56% of every line ever added. Whatever happened before that commit happened somewhere this repository cannot show you, so the early history is not available as evidence of how the system was designed.

Your response is published beside the finding, not instead of it. A finding you can argue with is the point — and a wrong one is calibration data we want.

An owner's response is removed only when it is unlawful, impersonates someone, publishes personal data or a credential, or is not about the finding. Disagreeing with the report is never a reason. To report a response, or to reach us about one, write to takedown@borehole.dev.

Notes that do not affect this rating
01.6

packages/leann-core/src/leann/cli.py is 4,026 lines, 21× this codebase's median file

adequate

The median source file here is 184 lines. 2 files exceed 1,840 lines, the largest being 4,026. 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.

68 errors caught and discarded in product code

adequate

68 places catch an error and do nothing with it, across 20 files (1.1 per thousand lines). Each is a failure the system will not report. They surface later as problems nobody can explain, and they are cheap to fix now.

Fixes are 52% of recent work, up from 33%

adequate

In the last two quarters 52% of commits were fixes, against 33% in the quarters before. Rising fix work usually means quality debt is coming due, and it takes time that new work would have had.

Evidence
fix share by quarter 57%, 48%, 40%, 27%, 38%, 25%

05.6

1 Dockerfile runs 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
no-USER-instruction docker/Dockerfile — runs as root

05.26

28 locked dependencies have published vulnerabilities, 47 high or critical in what ships

adequate worth checking first

28 of 242 locked dependencies match 120 published advisories in OSV, 49 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 uv.lock settles it. If it holds when someone checks it, this finding is significant.

Evidence
uv.lock uv.lock — anyio 4.11.0: GHSA-82r6-8w77-94w6 (critical), fixed in 4.14.2
uv.lock uv.lock — certifi 2025.8.3: GHSA-6q48-6c7w-9gw2 (critical), fixed in 2026.10.19

Notes that do not affect this rating
05.13

6 outbound calls can wait forever

adequate

6 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.

Evidence
packages/leann-core/src/leann/chat.py packages/leann-core/src/leann/chat.py:484 — outbound call without a timeout

6 deserialisers that can run code

adequate

6 places read data with a deserialiser that executes what it reads (pickle). That is safe on data the system wrote itself and remote code execution on anything else. Ask where each one's input comes from.

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.

Observability & Operations

06 · adequate · ratings ↑
06.1

No telemetry or error reporting is wired in anywhere

adequate

None of 278 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 278 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
logging-scan searched 278 files for 10 structured logging libraries; 0 matched

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

9 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.

07 · none coverage

Not rated: structurally not assessable from a repository.

  1. This is primarily a Python codebase. Does your engineering organisation already run Python in production, or would this be the first? 07.1
  2. The bulk of this system sits in packages/, apps/, data/. Which of your existing systems would each of those have to absorb or replace? 07.10
  3. The repository carries deployment configuration (docker/Dockerfile and 2 more). Does that match your deployment and on-call model, or does it need rehosting first? 07.2
  4. What is your tolerance for the findings above remaining unaddressed for the first two quarters after close, given everything else that will compete for this team's time?
  5. Which of these systems duplicate yours, and which get retired? Answer lives in: Your architecture07.11
  6. What will integration cost, and in what order? Answer lives in: The engagement07.12
  7. Where does the team land in your organisation, and who reports to whom? Answer lives in: Your org design07.13
  8. Are there earn-outs, retention packages or contractor IP to assign? Answer lives in: Deal terms07.14
  9. Do customer contracts limit hosting, regions or vendors? Answer lives in: Customer contracts07.15

A human assessment is Borehole's own paid service, €12,000+ (total price is determined per engagement; travel billed at cost). It is not independent of this report: the same business produced both. It is a separate contract, with its own scope, terms and reliance.

BOREHOLE READING NOT A CERTIFICATION WM4S-SAEY-MFAT 2026-10-23 · B415DF8 BOREHOLE.DEV/VERIFY

Anyone can check this report against the authoritative record — click the stamp, or enter WM4S-SAEY-MFAT 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/startrail-org/leann/b415df8.svg "Borehole free reading: not for reliance. See the full report.")](https://borehole.dev/verify/WM4SSAEYMFAT?via=badge)

Borehole reading WM4S-SAEY-MFAT, 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).
