Module normalize 

Lossless conversation-history validation before provider requests.

Validation never repairs history by deleting records or inventing tool outcomes. A missing, orphaned, duplicate, or misplaced record is returned as an explicit error so the host can recover it from durable state or block the request without changing canonical history.

Structs

NormalizeReport

Counts observed while validating a complete history.

Enums

HistoryValidationError

Why canonical history cannot be sent to a provider.

SyntheticReason

A terminal outcome proven by durable host state.

Constants

SYNTHETIC_CANCELLED_MARKER

Substring present in every explicitly recorded cancelled result body.

SYNTHETIC_ERROR_MARKER

Substring present in every explicitly recorded error result body.

Functions

normalize_history

Validate canonical tool call/result structure without modifying messages.

normalize_provider_messages

Validate the JSON message vector immediately before an LlmDriver request. The input remains byte-for-byte unchanged on success and failure.

synthetic_tool_result

Build a typed terminal result after the host has verified durable evidence.
