Inbox records previously called forwarding methods that called back into InputForwarding. TurnInboxReceiver and all six inbox/prompt deliver_to implementations are deleted. InputForwarding now declares the operations through existing MroDispatch; it consumes the most-specific handler because PreparedSession inherits UnwrittenPrompt and must prepare an idle session without sending a prompt. PreparedSession now lives with the prompt states rather than the native preparation launcher. TurnInbox declares its admitted item type.

FieldCodec.compact owns compact JSON layout. All 34 existing compact dumps/dump calls across 26 files use it, preserving each caller's encoded value, Unicode, key-order and NaN settings. It serializes the already encoded value; it does not walk the value through declaration encoding again. The one stdout dump becomes stdout.write(compact(...)), retaining its newline and flush. No store schema changes.

Removed forwarding sites at base f966a53: agent_backend.py:139 (receiver protocol), :189 (abstract delivery), :207 (InputRequest), :221 (SendNow), :236 (UseSettings), :246 (ClearQueue); prompt_state.py:67 (UnwrittenPrompt); native_session_prepare.py:35 (PreparedSession). The send/preparation algorithms now belong to InputForwarding.original_prompt and prepare_session. Single-operation selection at turn_inputs.py:95 uses the existing MroDispatch.handlers_for lookup directly; no narrowed consume_handlers override or second dispatch registry remains.

Removed compact-layout copies at base f966a53: working_memory_labels.py:47; selected_write_plan.py:223,:273; context_store.py:189; typed_table.py:275; acp_extension.py:402,:574; response_acknowledgement.py:20; cli_bridges/shared.py:802; connector_store.py:69; fresh_private_session.py:36; retained_task_facts.py:249; goal_attempts.py:601; selected_source_batch.py:88; assignment_states.py:366; context_segments/optional_awareness.py:182; audience_manifest.py:46; context_segments/wake.py:97,:102,:120,:151; turn_context.py:821,:1009,:1120; context_segments/awareness.py:23; context_segments/partner_activity.py:60; context_segments/relationships.py:26; pi_helper.py:98; threads.py:336; exporting.py:45; nk_foreground.py:119; private_sidecar.py:221,:370; goals.py:474. The single implementation is field_codec.py:1356. OwnedDispatchPhase now allows that canonical implementation and rejects compact-layout copies elsewhere, including single-quoted spellings missed by the old pattern.

Source ownership was traced with the existing NRA original class/consumer inventory (762 Core/paired-Toad/dependency modules; 6410 original classes; 8 local/conditional classes unprojected). The compact edits used NRA's original module syntax index on the selected files. The fleet integrator owns the combined touched-test run.

Shared hunks with #2667: agent_backend.py removes only inbox delivery and types its queue; turn_inputs.py changes dispatch and moves the send/preparation algorithms; private_sidecar.py changes only compact layout. Keep #2667's BusyInputPolicy and typed Pi streaming behavior when combining. plan_phases.py changes only OwnedDispatch evidence. The commander owns the separate WireOrigin.matches_sql fix in the merge batch.

Assumed: inbox inputs satisfy TurnInboxItem; the pinned native request contract stays unchanged; the integrator combines the shared hunks with #2667.

Latest source fixes: TurnInboxItem is declared before TurnInbox, so the queue names its actual type rather than a quoted spelling. Forwarding directly selects its most-specific declared handler, deleting the incompatible consume_handlers override. Compact JSON calls and imports in audience_manifest.py/response_acknowledgement.py are wrapped. The saved hosted findings at 9c517cf included tools/cutover/carry_dead_turns.py from the combined base; this branch does not edit that owner. The integrator runs the batch checks.
