serde-rs/serde: technical due diligence, read from its repository
What Borehole read in serde-rs/serde's code and history at 6693a89: 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
strongserde/src/private/de.rs is 3,502 lines, 218× this codebase's median file
adequateThe median source file here is 16 lines. 9 files exceed 1,000 lines, the largest being 3,502. 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
strongNo finding.
Product & Engineering Maturity
not assessableNot rated: only 8 of 19 checks could reach a conclusion here; the rest do not apply to this repository or could not read it.
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 361 tracked files; 0 present |
Observability & Operations
not assessableNot rated: only 4 of 16 checks could reach a conclusion here; the rest do not apply to this repository or could not read it.
Fit with the Acquirer
not assessableNot rated: structurally not assessable from a repository.
