CaseHub

casehub-platform defines thin, domain-agnostic SPIs (Path, Preferences, CurrentPrincipal) that every module in the stack can implement without framework dependencies. The three-tier model keeps platform-api pure Java while optional config and OIDC layers integrate cleanly with Quarkus via CDI.

The ledger provides immutable entries, attestations, and Bayesian trust scores with Merkle frontier operations for verifiable case and actor accountability. It enables GDPR Art.17 erasure, trust bootstrapping, and W3C PROV-DM lineage export without knowledge of business domain.

WorkItem coordinates humans via formal SLA policy, delegation, escalation, spawn semantics, and skill profiling with optional ledger attachment and distributed queue views. Usable standalone or integrated with CaseHub and Qhorus for multi-agent coordination.

Qhorus models every agent interaction as a typed speech act with commitments, shared artefacts, and channels — grounded in speech act theory and deontic logic. All writes flow through a single dispatch gate enforcing ACL, rate limiting, and ledger recording without bypass paths.

Provides built-in implementations for Slack, Teams, Twilio SMS, WhatsApp, and email using pure HttpClient with no external messaging framework dependencies. This is the canonical outbound notification infrastructure; any module needing alerts or escalations uses this SPI rather than implementing its own.

Eidos enables agents to register with identity, slot, capabilities, and disposition — then discover agents by slot or capability and render system prompts from descriptors. Any Quarkus app depending on casehub-eidos gains structured agent identity without touching LLM implementation.

The engine coordinates workers (AI agents, humans) via declarative case definitions, binding rules, and optional synchronous orchestration — supporting adaptive routing, synchronous tasks, and ledger attachment. Cases are defined in YAML or Java and persist via pluggable repositories.

Claudony owns session lifecycle management, wires CaseHub + Qhorus together, and surfaces them in a browser/PWA dashboard with WebSocket streaming. It operates in two modes: server (owns sessions) and agent (MCP endpoint for a controller Claude instance).
