### Dependency advisories — 49/100 (Weak)

Excluded from scoring (no data or not applicable): Indirect dependencies free of known advisories. Remaining weights renormalized. Matched 1204 resolved dependencies against OSV; 73 could not be assessed (no resolved version, an unsupported ecosystem, or beyond the reported package list). This repository publishes no package the index resolves, so the repository dependency graph was assessed instead. That graph mixes development and test pins with shipped dependencies, so only the declared runtime dependencies are scored; transitive findings are reported as context and excluded from the score. Reachability is not analyzed.

| Criterion | Status | Points | Detail |
|---|---|---|---|
| Direct dependencies free of known advisories | partial | 6.1 / 35 | 5 affected: google.golang.org/grpc v1.79.3 (critical 9.1), github.com/go-git/go-git/v5 v5.19.1 (high 7.1), bytes 1.10.0 (moderate 6.2), +2 more |
| Indirect dependencies free of known advisories | excluded | 0 / 25 | transitive set not separable from development and test dependencies in this scope |
| No advisories left outstanding | partial | 30.7 / 40 | 2 advisory-carrying package(s) unaddressed past 90 days; oldest published 205 days ago |

### Malicious dependencies — 100/100 (Exceptional)

| Criterion | Status | Points | Detail |
|---|---|---|---|
| No dependency reported as a malicious package | met | 100 / 100 | no dependency is reported as a malicious package |

### High-Risk Jurisdiction Exposure — 100/100 (Exceptional)

Only high-confidence self-published location evidence affects this multiplier. Ambiguous matches are review-only; country evidence is not proof of nationality, citizenship, legal registration, malicious intent, or sanctions status.

| Criterion | Status | Points | Detail |
|---|---|---|---|
| Policy exposure multiplier | met | 100 / 100 | no confirmed policy-scope location match |

## AI Readiness — 92/100 (Excellent)

How well is the repo equipped to be developed and maintained with AI coding agents? Carries a deliberately small weight: agent tooling is a real maintenance signal, but its absence must never gate the top of the scale (calibration saturates at raw 91, so 100/100 remains reachable with AI Readiness at zero).

### Agent context & guidance — 100/100 (Exceptional)
