Runtime Terms¶

Use these terms consistently across architecture docs, code review, and issue planning.

Stable IDs¶

Term	Meaning
`strategy_id`	Stable identity for one registered strategy instance
`execution_id`	Stable identity for one execution context
`route_id`	Stable identity for one named execution route
`broker_id`	Identity for the underlying broker or adapter binding behind a route
`snapshot_id`	Identity for one immutable shared runtime snapshot

Term	Meaning
Session	High-level owner for shared runtime construction and registrations
Reference data	Canonical instrument and venue metadata used by execution, simulation, and risk
State coordinator	Shared owner of observed state, projections, and snapshot materialization
Shared snapshot	The immutable per-step state view produced once for the active graph
Filtered view	The strategy-scoped slice of the shared snapshot handed to one strategy
Strategy registration	Binding of a strategy to a `strategy_id`, subscriptions, and optional execution/risk references
Execution context	Named execution surface that groups one or more routes
Route	Stable execution target bound to a broker/account adapter

Term	Meaning
Execution intent	Attributed request to submit, cancel, or modify execution behavior against a route
Order report	Normalized order lifecycle update emitted by the runtime or adapter
Fill report	Normalized fill lifecycle update with attribution and execution metadata
Inventory service	Central application point for execution reports into positions and exposure
Exposure view	Read model over inventory grouped by route, execution context, or symbol
Risk decision	Structured allow/reject outcome applied before execution submission
Post-trade sink	Hook that consumes normalized post-trade records after runtime processing
Control plane	Lightweight runtime surface for route status, operational gating, and kill-switch semantics

These terms still appear, but should not be treated as the whole architecture:

Term	How to read it now
Cerebro	Important compatibility/runtime entrypoint, not the whole system map
Feed	Market input surface within a broader shared-state runtime
Broker	One execution adapter or route binding within a broader execution model
Store	Exchange I/O and transport owner, not the owner of runtime orchestration
