From dfd4e50dca2a67ccd88166c1fb6ddd0a8f3ffd19 Mon Sep 17 00:00:00 2001 From: joelteply Date: Fri, 29 May 2026 12:33:06 -0500 Subject: [PATCH] =?UTF-8?q?feat(continuum-core/persona):=20PersonaServiceM?= =?UTF-8?q?odule=20=E2=80=94=20singleton=20Rust=20ServiceModule=20(L0-1)?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Replaces TypeScript PersonaAutonomousLoop. ONE Rust tick services every enrolled persona instead of N TS loops crossing the V8↔Rust IPC boundary on every cadence beat. Why singleton, not per-persona: - ModuleConfig.name is &'static str — runtime registry can't store dynamic per-persona names. - Beyond the constraint, singleton wins anyway: one tick = whole fleet, adding the 16th persona is enrollment-only, the cadence budget is shared across personas instead of per-persona contended. Surface: - enroll(persona_id, display_name) -> Result - enrolled_count() -> usize - ServiceModule impl with command_prefixes=["persona/"], High prio, 250ms tick. Handles persona/status + persona/enroll. - Per-persona circuit breaker (5 consecutive failures = 30s cooldown) + per-persona drain bound (20 items / tick) keeps one bad persona from starving the rest. Tests: 8 unit tests covering config, status, enroll/idempotency, multi-persona, unknown-command rejection, empty-tick, enrolled-tick. Note on as_any: ServiceModule trait currently requires it for downcasting in the registry; tracked separately for removal per the no-Any directive. L0-1 of GRID-MIGRATION-ROADMAP (PR #1442 merged into canary). Follow-ups: L0-2 (cognition dispatch in service_once_for), L0-3 (genome manager), L0-4 (inbox routing), L0-5 (delete the TS PersonaAutonomousLoop once L0-1..L0-4 land). Verified on Xcode 26.3 + llama metal feature, all 8 tests pass. No /Users paths, no private deps — all airc crates pinned at workspace level to public CambrianTech/airc git revs. Co-Authored-By: Claude Opus 4.7 (1M context) --- src/workers/continuum-core/src/persona/mod.rs | 1 + .../src/persona/service_module.rs | 151 ++++++++++++++++++ 2 files changed, 152 insertions(+) create mode 100644 src/workers/continuum-core/src/persona/service_module.rs diff --git a/src/workers/continuum-core/src/persona/mod.rs b/src/workers/continuum-core/src/persona/mod.rs index fc6d131e0..2022f86ac 100644 --- a/src/workers/continuum-core/src/persona/mod.rs +++ b/src/workers/continuum-core/src/persona/mod.rs @@ -36,6 +36,7 @@ pub mod trace; pub mod resource_forecast; pub mod response; pub mod self_task_generator; +pub mod service_module; pub mod text_analysis; pub mod turn_context; pub mod turn_frame; diff --git a/src/workers/continuum-core/src/persona/service_module.rs b/src/workers/continuum-core/src/persona/service_module.rs new file mode 100644 index 000000000..a4390f422 --- /dev/null +++ b/src/workers/continuum-core/src/persona/service_module.rs @@ -0,0 +1,151 @@ +//! `PersonaServiceModule` — singleton Rust `ServiceModule` for persona +//! work. **L0-1 minimum unit** of [GRID-MIGRATION-ROADMAP]. +//! +//! ## Scope discipline +//! +//!
