Crate astrid_capsule 

Core runtime management for User-Space Capsules in Astrid OS.

Core capsule runtime implementing the “Manifest-First” architecture. It provides the definition for Capsule.toml manifests, handles discovery, and routes execution to the appropriate environments (WASM sandboxes or legacy host processes).

Modules

capsule

Capsule trait and core types.

context

Capsule context types.

discovery

Capsule manifest discovery from standard locations.

dispatcher

Event dispatcher for routing events to capsule interceptors.

engine

Execution engine trait for Composite Capsules.

error

fuel_ledger

Shared per-principal CPU accounting ledger.

loader

Factory and routing logic for instantiating Composite Capsules.

manifest

Capsule manifest types.

memory_ledger

Shared per-principal peak-memory accounting ledger + the per-Store limiter that feeds it.

principal_class

Bounded principal-class label for telemetry and IPC host-fn audit labels. Used only for emitting bounded-cardinality metrics labels (3 buckets) — dispatcher routing (mpsc queues and chain_locks) is now keyed on the unbounded PrincipalKey so distinct user principals do not collide on a single class-keyed queue.

profile_cache

Process-lifetime cache of PrincipalProfile values, keyed by PrincipalId.

registry

Capsule registry.

schema_catalog

Topic schema catalog for A2UI integration.

security

Security gate trait for capsule host function calls.

topic

IPC topic matching for interceptor event patterns.

toposort

Topological sort for capsule dependency ordering.
