Detailed Description

Storage interface for conversation persistence.

Injected by the facade. Allows core.so to persist conversations, delegation records, and compaction snapshots without depending on storage.so. All callbacks are optional (nullptr = no-op).

Version

1.8.8

Member Data Documentation

complete_delegation

bool(* entropic::StorageInterface::complete_delegation) (const char *delegation_id, const char *status, const char *summary, void *user_data) = nullptr

Complete a delegation record.

Parameters

delegation_id	Delegation ID.
status	"completed" or "failed".
summary	Result summary (may be nullptr).
user_data	Opaque pointer.

Returns

true on success.

Definition at line 458 of file engine_types.h.

create_conversation

bool(* entropic::StorageInterface::create_conversation) (const char *title, std::string &conversation_id, void *user_data) = nullptr

Create a root conversation row.

Called once at AgentEngine::run() init when storage is wired so the engine's LoopContext::conversation_id is populated for the rest of the session. Pre-v2.1.12 (gh#48): no callback existed, root conversation_id stayed empty, every delegation's foreign-key insert into delegations(parent_conversation_id) failed silently against the empty parent string.

Parameters

	title	Display title (e.g., session description).
[out]	conversation_id	Newly created conversation ID.
	user_data	Opaque pointer.

Returns

true on success and conversation_id populated.

Version

2.1.12

Definition at line 417 of file engine_types.h.

create_delegation

bool(* entropic::StorageInterface::create_delegation) (const char *parent_id, const char *delegating_tier, const char *target_tier, const char *task, int max_turns, std::string &delegation_id, std::string &child_conversation_id, void *user_data) = nullptr

Create a delegation record with child conversation.

Parameters

	parent_id	Parent conversation ID.
	delegating_tier	Source tier.
	target_tier	Target tier.
	task	Task description.
	max_turns	Turn limit (0 = unlimited).
[out]	delegation_id	Created delegation ID.
[out]	child_conversation_id	Created child conversation ID.
	user_data	Opaque pointer.

Returns

true on success.

Definition at line 442 of file engine_types.h.

load_delegation_with_messages

bool(* entropic::StorageInterface::load_delegation_with_messages) (const char *delegation_id, std::string &result_json, void *user_data) = nullptr

Load a delegation's full child conversation (gh#32, v2.1.6).

Resolves the delegation by id, then loads the child conversation it spawned. Returns a JSON object whose top-level fields include target_tier, messages (array), and delegation_id. The engine uses this on resume_delegation to seed a fresh child context with the prior conversation history.

Parameters

	delegation_id	Delegation id (storage PK).
[out]	result_json	Conversation JSON (target_tier + messages).
	user_data	Opaque pointer (storage backend).

Returns

true on success and the delegation+conversation were found.

Definition at line 486 of file engine_types.h.

save_conversation

bool(* entropic::StorageInterface::save_conversation) (const char *conversation_id, const char *messages_json, void *user_data) = nullptr

Save messages to a conversation.

Parameters

conversation_id	Conversation ID.
messages_json	JSON array of message objects.
user_data	Opaque pointer.

Returns

true on success.

Definition at line 469 of file engine_types.h.

save_snapshot

bool(* entropic::StorageInterface::save_snapshot) (const char *conversation_id, const char *messages_json, void *user_data) = nullptr

Save a compaction snapshot (full history before compaction).

Parameters

conversation_id	Conversation to snapshot.
messages_json	JSON array of all messages.
user_data	Opaque pointer.

Returns

true on success.

Definition at line 427 of file engine_types.h.

user_data

void* entropic::StorageInterface::user_data = nullptr

Opaque pointer (storage backend)

Definition at line 491 of file engine_types.h.
