Crate oharness_core 

Core types, event schema, and context-plumbing traits for open-harness.

Zero-IO foundation. Every other crate in the workspace depends on this one.

Modules

assessment

Shared critic / reflector support types (plan §11.1, §11.4, §13.1).

capabilities

LlmCapabilities (§4.5). Returned by value from Llm::capabilities().

completion

Shared completion types (§4.9).

context

Context-plumbing traits (§4.6). Defined here so downstream crates can depend only on oharness-core when threading observability / budget / approval / cancellation.

event

Event schema (§4.7). The JSONL format is the source of truth for trajectory files.

ids

Identifier newtypes (§4.1).

message

Message & content types (§4.2).

outcome

RunOutcome and related types (§4.4) plus AgentError (§16.2).

task

Task and Attachment types (§4.3).

trajectory

TrajectoryHandle (§9.4) lives here in core so RunOutcome can carry it without every downstream crate depending on oharness-trace. The concrete sources a handle can point at (file, in-memory, stream) are enumerated here; the trace crate supplies the machinery that reads them.

view

ConversationView (§4.8). Read-only view over the conversation post memory-policy mangling — “what the LLM saw.”

Type Aliases

MetadataMap

Re-export of serde_json::Map<String, serde_json::Value> — the standard “metadata bag” type used on messages, events, tasks, etc.
