## Health v2 (maintenance only)
Score: 59/100 (v2, computed 2026-09-02T17:46:02.011165+00:00)
- activity 82, release rhythm 35, longevity 48
- inputs: {"age_days": 678, "days_push": 110, "days_rel": null, "gap_med": null, "n_releases_24m": 0}
- flags: no_releases, no_license
- formula: round(0.45*activity + 0.35*rhythm + 0.20*longevity); archived -> min(score, 10)

## What it is
Apple's source code for Private Cloud Compute (PCC), the infrastructure that runs Apple Intelligence requests in a privacy-preserving cloud environment. It is published so security researchers can independently verify PCC's security and privacy mechanisms.

## Use cases
- verify Apple Private Cloud Compute security claims
- audit privacy mechanisms in Apple's AI cloud infrastructure
- research verifiable cloud AI inference security
- study how Apple enforces privacy policies server-side
- security research on Apple Intelligence infrastructure

## When to choose
- you are a security researcher auditing Apple's PCC implementation
- you want to independently verify PCC's privacy and security properties
- you study secure cloud AI inference architectures

## When to avoid
- you want a ready-to-deploy cloud AI service
- you need production code to integrate into your own product
- you expect community contributions or general-purpose usage - it is published for verification only

## Facets
- artifact type: library
- maturity: active
- function: security, cryptography, privacy
- domain: security, privacy, large-language-models, cloud-computing
- platform: -
- tags: private-cloud-compute, apple, security-research, verifiable-computing, ai-privacy, macos, swift
