2noise/chattts: technical due diligence, read from its repository
What Borehole read in 2noise/chattts's code and history at 77b89ee: 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
strongNo finding.
Engineering Process & SDLC Maturity
strongAlmost 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.

Product & Engineering Maturity
adequateChange keeps returning to the same few files
adequateFive files out of 157 absorb 35% of all file-level change. Concentration like this is where debt is usually being serviced rather than repaid: the same code is reopened because it is load-bearing, fragile, or both. A repository cannot tell you which — that is a conversation with the team.
ChatTTS/core.py — 121 commits touched it |
README.md — 67 commits touched it |
ChatTTS/model/gpt.py — 59 commits touched it |
examples/web/funcs.py — 34 commits touched it |
examples/web/webui.py — 33 commits touched it |
10% of bug fixes add or change a test
adequateOf 129 fixes in the last 24 months, 13 touched a test. A fix without the test that would have caught the bug can quietly come back, and the suite never learns from what went wrong.

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 96 tracked files; 0 present |
16 dependencies float, and no lockfile is committed
adequateDependency versions are declared as ranges and no lockfile is committed, so a build today does not necessarily produce what a build last month produced. That matters twice over in a transaction: the thing being bought cannot be reproduced exactly, and a compromised upstream release arrives without anyone choosing to take it.

adequateThe root licence changed 2 time(s). Code taken under earlier terms stays under them; check which terms any fork or customer relied on.
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.
Fit with the Acquirer
not assessableNot rated: structurally not assessable from a repository.
