oomol-lab/pdf-craft: technical due diligence, read from its repository
What Borehole read in oomol-lab/pdf-craft's code and history at 0307a26: its licence, security advisories, releases, review practice, tests, dependencies and operations. Every finding cites the file and line it rests on. The full report also covers the team and asks the questions the code cannot answer.

Architecture & Codebase — including AI provenance
strongpdf_craft/pipeline/pdf/text_layout.py is 2,809 lines, 20× this codebase's median file
adequateThe median source file here is 136 lines. 1 file exceed 1,360 lines, the largest being 2,809. 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.

Engineering Process & SDLC Maturity
adequateAlmost no process scaffolding exists in the repository
adequateOf 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.
| 1 of 5 markers present across 684 tracked files |
5% of recent commits change more than 2,000 lines
adequate17 of 311 commits in the last 24 months changed over 2,000 lines of code, not counting reformatting, renames, vendored or generated code. A change that size is rarely reviewed line by line. Ask how they were reviewed, and what made them that large.
| 17 commits over 2,000 lines |
Product & Engineering Maturity
strongNo finding.
Security & Reliability Posture
adequateNone of the standard security guard rails are configured
adequateThere 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.
| checked 5 kinds of guard rail across 684 tracked files; 0 present |
34 deserialisers that can run code
adequate34 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.
pdf_craft/_process_worker.py:24 — code-executing deserialiser |
pdf_craft/_progress.py:156 — code-executing deserialiser |

Observability & Operations
not assessableNot rated: only 5 of 16 checks could reach a conclusion here; the rest do not apply to this repository or could not read it.
