tidyverse/dplyr: technical due diligence, read from its repository
What Borehole read in tidyverse/dplyr's code and history at d5e94e7: 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
strongR/join-by.R is 1,100 lines, 12× this codebase's median file
adequateThe median source file here is 90 lines. 2 files exceed 1,000 lines, the largest being 1,100. 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.
R/join-by.R:1 — 1,100 lines (12× median) |
R/across.R:1 — 1,049 lines (11× median) |
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
strongThe build runs third-party code it does not pin
adequate17 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.
.github/workflows/R-CMD-check.yaml:46 — action pinned by tag |
.github/workflows/R-CMD-check.yaml:48 — action pinned by tag |
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.
