lib-capabi

lib-capabi defines shared capability ABI primitives for EriX.

This repository centralizes capability-related constants and wire-level types used across kernel, root task, and early services.

Scope

lib-capabi is responsible for:

  • capability rights bitmasks and type identifiers
  • shared slot-ID constants for bootstrap contracts
  • transfer descriptor/layout types for capability handoff
  • validation helpers for rights and descriptor structure
  • common capability error/result enums

lib-capabi is not responsible for:

  • authority policy decisions
  • capability allocation strategy
  • revocation/recovery policy
  • service-specific delegation rules

Why this Exists

Without a shared capability ABI crate, slot IDs and rights semantics drift between kernel, root, and services, causing authority mismatches.

lib-capabi provides one canonical source for capability wire-level contracts.

Design Constraints

  • No external crates.
  • No ambient authority.
  • Validation-first for externally supplied descriptors.
  • Stable constants for v1 bootstrap slots and rights.

Relationship to Other Repos

  • kernel uses these types to expose capability semantics.
  • rootd uses them to validate and inventory received authority.
  • early services use them to validate startup capability intake.
  • lib-ipc and lib-bootstrap reference these types in payload schemas.

Status

Implemented baseline.

Current crate includes slot/rights registries, descriptor types, validation helpers, split Phase0 service role constants (memd, vspaced, pagerd, procd), and default intake-spec tables for each core service role.
