### Security posture — 19/100 (Critical)

Excluded from scoring (no data or not applicable): Branch-Protection. Remaining weights renormalized. A dependency reported as a malicious package applies a 35% multiplier to Security posture and gives it a Critical ceiling of 19.

| Criterion | Status | Points | Detail |
|---|---|---|---|
| Binary-Artifacts | met | 7.5 / 7.5 | no binaries found in the repo |
| Branch-Protection | excluded | 0 / 7.5 | internal error: error during branchesHandler.setup: internal error: some github tokens can't read classic branch protection rules: https://github.com/ossf/scorecard-action/blob/main/docs/authentication/fine-grained-auth-token.md |

### Dependency advisories — 79/100 (Good)

Excluded from scoring (no data or not applicable): Indirect dependencies free of known advisories. Remaining weights renormalized. Matched 2524 resolved dependencies against OSV; 18 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 | 22.6 / 35 | 6 affected: rand 0.8.5 (low), rand 0.9.2 (low), tracing-subscriber 0.2.25 (low), +3 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 | 36.4 / 40 | 4 advisory-carrying package(s) unaddressed past 90 days; oldest published 384 days ago |

### Malicious dependencies — 35/100 (Weak)

1 resolved dependency(ies) resolve to a version the registry still serves and the OpenSSF corpus reports as malicious. Direct and indirect are treated alike: an install-time payload runs at any depth in the graph. A report here concerns the package as published, not the maintainers of this repository, which may have resolved it unknowingly.

| Criterion | Status | Points | Detail |
|---|---|---|---|
| No dependency reported as a malicious package | partial | 35 / 100 | 1 reported as malicious: fs 0.0.1-security |

### 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 — 95/100 (Exceptional)

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)

| Criterion | Status | Points | Detail |
|---|---|---|---|
| Agent instructions | met | 45 / 45 | CLAUDE.md |
| Machine-readable docs (llms.txt) | met | 15 / 15 | llms.txt served by the project website (https://docs.polkadot.com/llms.txt) |
| Legible commit history | met | 40 / 40 | 74 of 76 human commits state their intent (structured subject or explanatory body) |

### Verify loop (build / test / typecheck) — 89/100 (Excellent)

| Automated maintenance | met | 8 / 8 | 24 of the last 100 commits are automated dependency updates |
| OpenSSF Scorecard: Pinned-Dependencies | partial | 9 / 10 | dependency not pinned by hash detected -- score normalized to 9 |

| Criterion | Status | Points | Detail |
|---|---|---|---|
| Type-checkable code | met | 45 / 45 | Rust (statically typed) |
| Manageable file sizes | partial | 53.6 / 55 | 6/236 source files over 60KB |

### Machine-readable interfaces — 100/100 (Exceptional)

Excluded from scoring (no data or not applicable): MCP server. Remaining weights renormalized.

| Criterion | Status | Points | Detail |
|---|---|---|---|
