Constructs and validates AppContext, including database pools, configuration, registries, authorization and analytics handles used by the runtime.

Layer: App, orchestrates domain modules. Part of the systemprompt-core workspace.

Overview

This crate:

  • Builds and holds AppContext, the central runtime state container.
  • Registers module routes at compile time through inventory macros.
  • Validates system configuration and extensions before the server accepts traffic.
  • Coordinates domain services without implementing business logic.

Modules

Module Purpose
context AppContext and its planes (DataPlane, ConfigPlane, Plugins, Subsystems), plus the GeoIP and content-config loaders
builder AppContextBuilder fluent construction (with_extensions, with_marketplace_filter) and plane assembly
registry Compile-time module registration and routing (ModuleApiRegistry, ModuleApiRegistration, ModuleType, WellKnownRoute)
startup_validation StartupValidator across files, rate limits, web/content config, agents, MCP servers, AI providers, and extensions
database_context DatabaseContext, a database-only context for CLI tools that do not need the full runtime
span create_request_span, builds a tracing span with user, session, trace, and context IDs
wellknown .well-known endpoint metadata registry (WellKnownMetadata, get_wellknown_metadata)
validation Runtime prerequisite checks (validate_system, validate_database_path)
error RuntimeError / RuntimeResult, the typed error model for construction and validation

AppContext is assembled either through AppContextBuilder (the bootstrap path: ProfileBootstrap, database init, extension discovery, optional GeoIP and content config, tracing with database persistence) or directly through AppContext::from_parts(data, cfg, plugins, subsystems) for tests and embedders that own plane construction.
