From 4031f41d5ded88d93cee5b5467e5f61e0d225f59 Mon Sep 17 00:00:00 2001 From: joelteply Date: Fri, 29 May 2026 16:05:43 -0500 Subject: [PATCH] =?UTF-8?q?feat(continuum-core/persona):=20L0-2-dispatch?= =?UTF-8?q?=20=E2=80=94=20service=5Fonce=5Ffor=20through=20full=5Fevaluate?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Builds on L0-2-prep (#1464). Each EnrolledPersona now carries its own ChannelRegistry + PersonaState, and the service module has the dispatch path wired through the unified pre-response gate. Why the slot rename: - L0-2-prep introduced `service_module::PersonaSlot` which collided with the existing `cognition::response_orchestrator::PersonaSlot` (a minimal identity+specialty DTO used as input to respond()). - Renamed mine to `EnrolledPersona` — clearer name AND no collision. What changes: - EnrolledPersona extends with channels: ChannelRegistry + state: PersonaState (initialized fresh in enroll) - service_once_for(persona, now_ms) — pops via channels.service_cycle, deserializes the chat item (local ChatItemWire struct matching the camelCase to_json output), builds a FullEvaluateRequest, calls full_evaluate, returns the decision as ServiceOnceOutcome - drain_all_personas(now_ms) — iterates enrolled personas, calls service_once_for up to MAX_DRAIN_PER_TICK (20) per persona, manages per-persona circuit breaker (5 consecutive failures → 30s cooldown) - tick now calls drain_all_personas - ServiceOnceOutcome enum: Idle | Evaluated{message_id,decision} | UnsupportedItem{item_type} — voice + task items surface as UnsupportedItem rather than silently dropped (anti-fallback) Production safety: - No production code calls persona/enroll yet. The runtime invokes tick() every 250ms but with zero enrolled personas it's a no-op. - L0-2-cutover will atomically (a) wire persona/enroll from production, (b) delete PersonaAutonomousLoop.ts, (c) make Rust the production driver of the loop. What does NOT change yet: - No call to respond() — that needs upstream TurnContext + room history + known-specialties roster that lives in PersonaMessageEvaluator today. Follow-up slice wires respond() with the upstream context plumbed through. - No TS deletions yet. Constants: - CIRCUIT_BREAKER_MAX_CONSECUTIVE_FAILURES: 5 - CIRCUIT_BREAKER_COOLDOWN_MS: 30_000 - MAX_DRAIN_PER_TICK: 20 Tests: 16 passing (10 L0-2-prep + 6 new dispatch tests). - service_once_for_idle_returns_idle - service_once_for_dispatches_chat_item_through_full_evaluate - drain_all_personas_processes_two_personas_independently - drain_respects_max_drain_per_tick - tick_with_no_enrolled_personas_succeeds_quietly - tick_with_enrolled_persona_and_no_items_is_no_op Verified on Xcode 26.3 + llama/metal feature.
