Detailed Description

librentropic facade — C API implementation.

Owns the EntropicEngine handle struct and implements lifecycle (create/configure/destroy), generation, and subsystem stubs. Stubs are wired to real subsystems across Phases 0-5.

Version

2.0.0

Definition in file entropic.cpp.

Function Documentation

alloc_cstr() [1/2]

static char * alloc_cstr ( const char *  src )

static

Allocate a C string copy via the engine allocator.

Uses entropic_alloc so the caller can free with entropic_free(). Returns NULL on allocation failure (OOM).

Parameters

src	Source string (null-terminated).

Returns

Heap-allocated copy, or NULL on OOM. @utility

Version

2.0.1

Definition at line 46 of file entropic.cpp.

alloc_cstr() [2/2]

static char * alloc_cstr ( const std::string &  src )

static

Allocate a C string copy from std::string.

Parameters

src	Source string.

Returns

Heap-allocated copy, or NULL on OOM. @utility

Version

2.0.1

Definition at line 61 of file entropic.cpp.

apply_identity_frontmatter()

static void apply_identity_frontmatter ( entropic_handle_t  h, const std::string &  name, const entropic::prompts::IdentityFrontmatter &  fm  )

static

Cache per-tier frontmatter fields (allowed_tools, validation_rules, relay).

Parameters

h	Engine handle with config + engine constructed.
data_dir	Bundled data directory.

Apply a parsed identity's frontmatter to the engine handle.

Parameters

h	Engine handle.
name	Tier name.
fm	Parsed frontmatter.

Definition at line 762 of file entropic.cpp.

build_assembled_prompt_for_tier()

static std::string build_assembled_prompt_for_tier ( entropic_engine *  h, const std::string &  tier_name  )

static

Build the assembled system prompt the engine would send for a given tier (constitution + app_context + identity body + tool defs).

Returns "" on any failure.

Demo ask #3 (v2.1.0). Static parts only — does NOT include the per-turn iteration / validation reminders, since those are runtime-dependent. Runtime augmentations live in ResponseGenerator::inject_engine_state_reminder.

@utility

Version

2.1.0

Definition at line 1007 of file entropic.cpp.

build_loop_config()

static entropic::LoopConfig build_loop_config ( entropic_handle_t  h )

static

Build LoopConfig from parsed config.

Parameters

h	Engine handle with config populated.

Returns

Populated LoopConfig. @utility

Version

2.0.6

Definition at line 1324 of file entropic.cpp.

build_shared_prompt_prefix()

static std::string build_shared_prompt_prefix ( entropic_handle_t  h, const std::filesystem::path &  data_dir  )

static

Build shared system prompt prefix (constitution + app_context).

Parameters

h	Engine handle with config loaded.
data_dir	Bundled data directory.

Returns

Concatenated prefix string. @utility

Version

2.0.4

Definition at line 731 of file entropic.cpp.

build_storage_iface()

static entropic::StorageInterface build_storage_iface ( entropic::SqliteStorageBackend *  sb )

static

Build a populated StorageInterface bound to sb.

gh#32 (v2.1.6): pre-2.1.6 nothing called AgentEngine::set_storage so the engine's StorageInterface fields were all nullptr and the delegation/compaction storage paths were dead code. This builder closes that gap.

Parameters

sb	Storage backend (non-owning).

Returns

StorageInterface ready to pass to AgentEngine::set_storage.

Definition at line 633 of file entropic.cpp.

cache_tier_allowed_tools()

static void cache_tier_allowed_tools ( entropic_handle_t  h, const std::filesystem::path &  data_dir  )

static

Cache per-tier frontmatter fields from identity files.

Parameters

h	Engine handle with config + engine constructed.
data_dir	Bundled data directory.

Definition at line 784 of file entropic.cpp.

check_identity()

static entropic_error_t check_identity ( entropic_handle_t  h )

static

Check handle prerequisites for identity manager APIs.

Parameters

h	Engine handle.

Returns

ENTROPIC_OK if valid, error code otherwise.

Definition at line 134 of file entropic.cpp.

check_mcp_auth()

static entropic_error_t check_mcp_auth ( entropic_handle_t  h )

static

Check handle prerequisites for MCP auth APIs.

Parameters

h	Engine handle.

Returns

ENTROPIC_OK if valid, error code otherwise.

Definition at line 119 of file entropic.cpp.

check_orchestrator()

static entropic_error_t check_orchestrator ( entropic_handle_t  h )

static

Check handle prerequisites for orchestrator APIs.

Parameters

h	Engine handle.

Returns

ENTROPIC_OK if valid, error code otherwise.

Definition at line 104 of file entropic.cpp.

collect_delegatable_tiers()

static std::vector< std::string > collect_delegatable_tiers ( const entropic::ParsedConfig &  config )

static

Collect valid delegation targets from handoff_rules.

Only tiers that appear as TARGETS in handoff_rules are included. Sources are excluded — a tier should not appear in its own delegate enum (self-delegation creates a worktree cycle for no purpose and confuses small models).

When handoff_rules is empty, falls back to all configured tiers except the default tier (preserves delegation for simple configs that define multiple tiers without explicit routing).

Parameters

config

Parsed engine config.

Returns

Deduplicated tier names for delegate/pipeline schemas. @utility

		const char *	adapter_name,
		const char *	adapter_path,
		const char *	base_model_path,
		float	scale

	)

Enqueue a follow-up user message while a run is in flight.

Queue a user message to be injected at the next top-level turn boundary.

Pure passthrough to the engine's thread-safe queue primitive.

The orchestrator fires the lambda synchronously on each load / evict / activation_swap transition; the lambda forwards to the C callback with the residency-event enum, tier name, model path, and footprint.

entropic_set_state_observer()

entropic_error_t entropic_set_state_observer	(	entropic_handle_t	handle,
		void(*)(int state, void *user_data)	observer,
		void *	user_data
	)

Register a state-change observer on the handle.

Register an engine state-change observer.

v2.1.10 (gh#40 fallout): routes through the engine's persistent state_observer slot rather than the legacy EngineCallbacks.on_state_change. The legacy path is wiped by run_streaming's set_callbacks() shuffle, which silently broke the documented external-MCP-bridge use case for streaming runs.

Parameters

handle	Engine handle.
observer	State observer (NULL to clear).
user_data	Forwarded to observer.

Returns

ENTROPIC_OK on success.

Definition at line 2129 of file entropic.cpp.

entropic_set_stream_observer()

entropic_error_t entropic_set_stream_observer	(	entropic_handle_t	handle,
		void(*)(const char *token, size_t len, void *user_data)	observer,
		void *	user_data
	)

Set a global stream observer callback.

Parameters

handle	Engine handle.
observer	Token callback (NULL to clear).
user_data	Forwarded to observer.

Returns

ENTROPIC_OK on success.

entropic_speculative_compat()

entropic_error_t entropic_speculative_compat	(	entropic_handle_t	handle,
		int *	compatible,
		char **	diagnostic
	)

Query speculative-decoding compatibility for the configured target/draft pair.

Query whether the configured target/draft pair is compatible for speculative decoding.

Delegates to ModelOrchestrator::check_speculative_compat(). The orchestrator owns both sides of the pairing (active main tier as target, "draft" role on the secondary loader as draft) and runs the architecture + tokenizer rules from entropic::speculative::check_compat.

Parameters

handle	Engine handle.
compatible	Required out-param: 1 when compatible.
diagnostic	Optional out-param: heap-allocated diagnostic string on incompatibility (NULL on compatible pair). Caller frees with entropic_free_string.

Returns

ENTROPIC_OK / ENTROPIC_ERROR_INVALID_HANDLE / ENTROPIC_ERROR_INVALID_STATE.

Definition at line 3516 of file entropic.cpp.

entropic_throughput_reset()

void entropic_throughput_reset	(	entropic_handle_t	handle,

Parameters

handle	Engine handle returned by entropic_create.
model_path	Path or registry key identifying the model whose throughput should be reset.

Definition at line 2940 of file entropic.cpp.

entropic_throughput_tok_per_sec()

		const char *	model_path
	)

Get EWMA throughput estimate in tokens per second.

Get current throughput estimate for a model.

Delegates to ThroughputTracker::tok_per_sec(). Returns the smoothed estimate from recent generations. model_path is accepted for API compatibility but the orchestrator tracks a single global throughput (one tracker, not per-model).

Returns

Tokens per second estimate, or 0.0 on error/no data.

static void init_engine_and_interfaces ( entropic_handle_t  h, const std::filesystem::path &  data_dir  )

static

Build the engine + inference interfaces (configure step 2).

Extracted from configure_common to keep it knots-clean. Creates the MCP-auth + identity managers, the per-handle orchestrator interface (gh#58), the AgentEngine, and rewires observers/interrupt/tools.

Parameters

h	Engine handle.
data_dir	Resolved data directory.

Definition at line 1432 of file entropic.cpp.

init_mcp_servers()

static void init_mcp_servers ( entropic_handle_t  h, const std::filesystem::path &  data_dir  )

static

Shared body of all entropic_configure* entry points.

Construct the orchestrator + grammar fallback for a handle.

Extracted from configure_common in v2.2.9 to keep SLOC under the knots gate after v2.2.6's per-handle InterfaceContext wiring grew the body past 50 lines.

static

Parse messages_json and check vision-tier availability (gh#37/gh#41).

Parses the wire-format messages array via the shared utility and, if any message carries image content_parts, verifies that the orchestrator has at least one tier whose capabilities includes "vision". Returns the parsed vector on success; throws on parse failure (caller catches and maps to ENTROPIC_ERROR_*).

Parameters

data_dir	Resolved data directory for identity files.
shared_prefix	Prefix assembled from constitution + app context. @utility

Version

2.0.6-rc18

Definition at line 451 of file entropic.cpp.

reject_if_configured()

static entropic_error_t reject_if_configured ( entropic_handle_t  h )

static

Post-parse config setup: subsystem construction + wiring.

v2.1.10 (gh#40 + fallout): observer rewiring at engine construction is bundled into rewire_observers so pre-configure stream, queue, and state observers all survive engine construction AND the EngineCallbacks shuffle that run_streaming performs.

Parameters

h	Engine handle with config populated.

Returns

ENTROPIC_OK or error code.

Refuse a second configure on the same handle (gh#58).

Re-configure would leak raw pointers captured during the first pass into subsystems that already wired against the original orchestrator/engine/mcp_auth.

Definition at line 1382 of file entropic.cpp.

require_active_backend()

static entropic::InferenceBackend * require_active_backend ( entropic_handle_t  h, const char *  tier_name  )

Post-parse config setup: load bundled models, set configured.

Parameters

h	Engine handle.

Returns

ENTROPIC_OK or error code.

Pre-load bundled models from default locations.

Tries compile-time and source-tree data dirs before config is parsed, so registry keys resolve during config loading.

Parameters

h	Engine handle.

Resolve allowed_tools list for a tier.

Checks identity config first, then model config fallback. Empty result means all tools are allowed (no filter).

Parameters

h	Engine handle.
tier	Tier name.

Returns

Allowed tool names (empty = all allowed). @utility

Version

2.0.4

rewire_critique_callbacks()

static void rewire_critique_callbacks ( entropic_handle_t  h )

static

Propagate pre-configure critique callbacks to a newly- constructed ConstitutionalValidator (gh#50, v2.1.12).

Same pattern as rewire_state_observer: the handle owns the authoritative slot; configure_common reconstructs the validator each call, so the rewire helper re-applies the consumer's registered callbacks after every (re)construction.

Parameters

h	Engine handle with validator just constructed (or NULL). @utility

Version

2.1.12

Definition at line 411 of file entropic.cpp.

rewire_observers()

static void rewire_observers ( entropic_handle_t  h )

static

Re-bind every pre-configure observer to the new engine.

Aggregates the three rewire helpers so configure_common stays under the SLOC ceiling. (gh#40 fallout, v2.1.10)

Parameters

h	Engine handle with engine just constructed. @utility

Version

2.1.12

Definition at line 431 of file entropic.cpp.

rewire_queue_observer()

static void rewire_queue_observer ( entropic_handle_t  h )

static

Propagate any pre-configure queue observer to the new engine.

Sibling of rewire_stream_observer for the mid-gen queue consumption callback (gh#40, v2.1.10). Re-binds the handle-stored observer when the AgentEngine is constructed so observers never miss queue-consumption events on a late-bound engine.

Parameters

h	Engine handle with engine just constructed. @utility

Version

2.1.10

Definition at line 372 of file entropic.cpp.

rewire_state_observer()

static void rewire_state_observer ( entropic_handle_t  h )

static

Propagate any pre-configure state observer to the new engine.

gh#40 fallout (v2.1.10): pre-existing behavior wired the observer via engine->set_callbacks(), which is wiped by run_streaming. Re-bind through the persistent slot so pre-configure registrations survive engine construction AND streaming runs.

Parameters

h	Engine handle with engine just constructed. @utility

Version

2.1.10

Definition at line 391 of file entropic.cpp.

rewire_stream_observer()

static void rewire_stream_observer ( entropic_handle_t  h )

static

Propagate any pre-configure stream observer to the new engine.

Handles the edge case where a caller registers a stream observer before entropic_configure() — the handle stores it on arrival, and this helper re-binds it when the AgentEngine is constructed so observers never miss tokens on a late-bound engine. (P0-1)

Parameters

h	Engine handle with engine just constructed. @utility

Version

2.0.6-rc16

Definition at line 353 of file entropic.cpp.

run_messages_inner()

static entropic_error_t run_messages_inner ( entropic_handle_t  handle, const char *  messages_json, char **  result_json  )

static

Blocking multimodal run (gh#37, v2.1.8).

Inner blocking-run dispatch — no front validation (gh#37).

Caller has already verified handle, args, and engine pointer. Parses messages, runs the multimodal vision check, dispatches the turn, serializes the result, and fires the synthetic stream-observer completion sentinel. Returns the canonical entropic_error_t status — single exit.

Definition at line 1892 of file entropic.cpp.

run_messages_stream_inner()

si_create_conversation()

static bool si_create_conversation ( const char *  title, std::string &  conversation_id, void *  user_data  )

static

StorageInterface bridge: create_conversation trampoline.

Forwards AgentEngine::run's root-conversation creation to the SqliteStorageBackend. Pre-v2.1.12 (gh#48) the interface had no create_conversation callback, so the root conversation row was never inserted and every subsequent delegation's FK to conversations(id) failed silently against the empty parent id.

@callback

Version

2.1.12

Definition at line 519 of file entropic.cpp.

si_create_delegation()

static bool si_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  )

static

Initialize persistence: storage + session logger.

Parameters

h	Engine handle with config.log_dir set.

StorageInterface bridge: create_delegation trampoline.

Translates the engine's StorageInterface callback into a call against SqliteStorageBackend::create_delegation. gh#32 (v2.1.6) closes a pre-existing wiring gap: the engine declared the interface but the facade never populated it, so per-delegation storage records were silently dropped. This is the bridge that finally connects them.

@callback

si_load_delegation_with_messages()

static bool si_load_delegation_with_messages ( const char *  delegation_id, std::string &  result_json, void *  user_data  )

static

StorageInterface bridge: load_delegation_with_messages.

Resolves delegation id → child_conversation_id → conversation messages, then returns the composed JSON with target_tier and messages at the top level. Used by entropic.resume_delegation (gh#32, v2.1.6).

sp_get_history()

static char * sp_get_history ( int  max_entries, void *  ud  )

static

State provider: get_history — conversation context snapshot.

@callback

Returns the current conversation as a JSON array of {role, content_preview, token_count_est} objects, suitable for context_inspect MCP tool and inspect –target history. (P2-16)

Content previews are truncated at 200 bytes on a UTF-8 codepoint boundary via entropic::facade::utf8_safe_substr — byte-indexed truncation would slice multi-byte codepoints and cause arr.dump() below to throw nlohmann::json::type_error.316 (gh#56).

Parameters

max_entries	Maximum messages to return (0 = all).
ud	Engine handle.

Returns

JSON array string (caller frees via free()).

sp_get_identities()

static char * sp_get_identities ( void *  ud )

static

State provider: get_identities.

Returns an array of objects per tier: [{"name":"lead","assembled_prompt":"…"}, ...]

The assembled_prompt is the static system prompt the engine would send for that tier (constitution + app_context + identity body + tool defs), excluding per-turn runtime augmentations. Demo ask #3: lets entropic.inspect identity <tier> return what the model actually sees, without running inference. (v2.1.0)

Version

2.1.0

Definition at line 1060 of file entropic.cpp.

sp_get_metrics()

wire_external_interrupt()

static void wire_external_interrupt ( entropic_handle_t  h )

static

Wire engine interrupt propagation into MCP transports (P1-10).

Extracted from configure_common to keep that function under the 50-SLOC quality gate. On first interrupt(), the lambda calls ServerManager::interrupt_external_tools() which trips the cancel flag in every StdioTransport so in-flight reads return within ~100ms.
