Platform Matrix

The pyhall compiler generates governed adapters from a single canonical skill manifest. This page documents which platforms are supported, at what tier, and what each adapter provides.

Tier definitions

TierMeaning
Tier 1First-class support. Ships with the core compiler. Full attestation + governance chain.
Tier 2Framework adapters. Ships after Tier 1 is stable. Same governance model.
Tier 3Integration guides + HTTP adapter. Any platform that speaks HTTP can use the pyhall governance gate.
GenericPortable schema export. No framework-specific runtime wrappers.

What every adapter includes

Regardless of platform, every generated adapter:

  • References the canonical manifest hash
  • Carries the registry certification ID
  • Wraps execution in the pyhall governance gate call
  • Emits structured audit events on every invocation
  • Respects deny-by-default: if attestation fails, execution is denied

Governance chain

Caller invokes skill
        │
        ▼
pyhall decision gate
  ├─ validate manifest hash
  ├─ check worker attestation
  ├─ evaluate WCP policy
  ├─ check ban list
  └─ ALLOW or DENY
        │
        ▼
   Platform adapter
   executes tool
        │
        ▼
   Audit record written

No platform adapter can bypass this chain. Generated wrappers do not contain direct execution logic — they route through the governance gate.

Version compatibility

Platform APIs change. When a breaking change is detected:

  • The adapter is marked degraded in the registry
  • pyhall skill certify blocks certification for the affected target
  • Docs and warnings are updated
  • The canonical manifest is unaffected — only the specific adapter target is flagged
