Ccmd_reply_t
Cdual_poll_result_t	Result of one dual_channel_poll_link_once() attempt
Cfifo_channel_config_t
Cflow_channel_state_t
Cmulti_site_config_t
Cmulti_site_voter_t
Cmulti_transport_channel_t
C[union].impl
Crte_appmanager_checkpoint_config_t	Optional built-in checkpoint rendezvous configuration (ADR-019/ADR-034)
Crte_appmanager_config_t	Application manager configuration
Crte_appmanager_operations_t	Application lifecycle operations
Crte_appmanager_state_t	Application manager runtime state
Crte_buffer_t	Mutable, bounds-tracked view over caller-owned storage
Crte_channel_config_t	Configuration for rte_channel_init()
Crte_channel_def_t
Crte_channel_health_t	Health statistics for one vital channel
Crte_channel_service_storage_t	Caller-owned storage for one named channel service instance
Crte_channel_storage_t	Storage for one vital channel instance (opaque to caller)
Crte_checkpoint_config_t	Checkpoint configuration
Crte_checksum_manager_t
Crte_checksum_result_t	Checksum result for validation
Crte_checksum_stats_t	Checksum statistics for monitoring
Crte_const_buffer_t	Read-only view of a buffer's currently valid bytes. Grants no write access to the underlying storage
Crte_cross_comparator_config_t	Configuration for rte_cross_comparator_init()
Crte_cross_comparator_storage_t	Storage for one cross-comparator instance (opaque to caller). No dynamic memory
Crte_dual_ack_frame_t	RTE_DUAL_FRAME_KIND_ACK payload
Crte_dual_channel_config_t	Configuration for rte_dual_channel_init()
Crte_dual_channel_t	One rte_dual_channel_t instance's state. Caller-owned storage; every field is private - reach it only through the functions below
Crte_dual_frame_header_t	Common 4-byte header prefixing every Layer-2 frame; kept a fixed 4 bytes (not just 1) so the fields that follow in rte_dual_ack_frame_t/rte_dual_state_frame_t stay naturally aligned
Crte_dual_heartbeat_frame_t	RTE_DUAL_FRAME_KIND_HEARTBEAT payload - connection maintenance heartbeat
Crte_dual_msgchannel_config_t	Configuration for rte_dual_msgchannel_init()
Crte_dual_msgchannel_t	One rte_dual_msgchannel_t instance's state. Caller-owned storage (REQ-DUAL-MSGCHANNEL-001); opaque in practice, exposed here (not via RTE_DECLARE_STORAGE) only because its size is already small and fixed - callers must still treat every field as private and only reach it through the functions below
Crte_dual_negotiator_config_t	Configuration for rte_dual_negotiator_init()
Crte_dual_negotiator_t	One rte_dual_negotiator_t instance's state. Caller-owned storage; every field is private - reach it only through the functions below
Crte_dual_state_frame_t	RTE_DUAL_FRAME_KIND_STATE payload - rte_dual_negotiator_t's own periodic beacon
Crte_election_candidate_t	One candidate's info for one rte_election_execute() call. The caller builds this array fresh each call from whatever transport it uses to learn about the other replicas - this module does not retain it between calls except via the state recomputed into rte_election_t itself
Crte_election_config_t	Configuration for rte_election_init()
Crte_election_t	One rte_election_t instance's state. Caller-owned storage; every field is private - reach it only through the functions below
Crte_flow_attr_t	Flow attributes (OCORA PI API Annex A.1 leaves fl_attr's content as "to be defined" - this is this framework's own concrete, deliberately minimal choice of static+dynamic attributes, not a claim of OCORA-authored content)
Crte_flow_config_t	Configuration for rte_flow_open()
Crte_ipc_config_t	Configuration for rte_ipc_create()
Crte_ipc_pubsub_subscriber_config_t	Configuration for a subscriber
Crte_ipc_pubsub_topic_config_t	Configuration for a pub-sub topic
Crte_ipc_rr_client_config_t	Configuration for request-reply client
Crte_ipc_rr_request_t	Incoming request with context for sending reply
Crte_ipc_rr_server_config_t	Configuration for request-reply server
Crte_log_fields_t	Bounded builder for rte_log_write_event()'s extra_fields (or info) argument: accumulates space-separated key=value pairs, each typed at the call site, so a caller adding a couple of variable values does not hand-roll a rte_string_concat()/rte_string_append_u32() chain every time (MISRA C:2012 Rule 17.1 rules out a printf-style variadic here)
Crte_log_level_name_t	One canonical level spelling <-> value pair for rte_log_level_from_string()
Crte_mem_pool_config_t	Configuration for rte_mem_pool_create()
Crte_netlink_config_t	Configuration for rte_netlink_open()
Crte_nvm_config_t	Configuration for rte_nvm_open()

Crte_osadapter_flow_t	OSAdapter Flow operations vtable
Crte_osadapter_fsou_t	OSAdapter FSOU operations vtable
Crte_osadapter_ipc_t	OSAdapter IPC operations vtable
Crte_osadapter_log_t	OSAdapter logging operations vtable

Crte_osadapter_task_t	OSAdapter task scheduling operations vtable
Crte_osadapter_timer_t	OSAdapter timer operations vtable
Crte_protocol_adapter_ops_t	Operations vtable implemented by a concrete ProtocolAdapter
Crte_protocol_config_t	Configuration passed to open a protocol adapter instance
Crte_protocol_tcp_state_t
Crte_protocol_udp_state_t
Crte_redundancy_config_t
Crte_safe_ptr_t	A bounds-checked, canary-protected wrapper around one raw memory region. Opaque to callers in spirit (every field is manipulated only through the functions below) but a plain struct, not a handle, so it can be embedded directly in a caller's own statically-allocated storage - no dynamic allocation, matching CLAUDE.md
Crte_safechannel_config_t	Configuration for rte_safechannel_open()
C[union].as
Crte_safechannel_dual_config_t	Configuration specific to RTE_SAFECHANNEL_TYPE_DUAL_REDUNDANT
Crte_safechannel_endpoint_t	One remote endpoint to open internally - replaces a caller- supplied rte_netlink_handle_t (ADR-022 section 2.2)
Crte_safechannel_t	Caller-owned storage for one rte_safechannel_t instance. Every field is private - reach it only through the functions below. No dynamic allocation (REQ-SAFECHANNEL-002): sized to hold up to RTE_SAFECHANNEL_MAX_LINKS opened netlink links plus whichever of rte_dual_channel_t/rte_channel_t is in use
C[union].impl
C[struct].impl.vital
