architecturally:

```text
ui/cli/api
    ↓
interfaces layer
    ↓
application/orchestration layer
    ↓
domain/core layer
    ↓
ports/contracts
    ↓
infrastructure layer
```

rules:

* core NEVER imports infrastructure
* infrastructure implements ports/interfaces from core
* plugins only talk through contracts
* ui never touches persistence directly
* projections are rebuildable only from events
* tools never mutate state directly
* models never own memory/state
* router never owns execution state

important internal split

1. domain/core (pure deterministic logic)

contains:

* events
* transitions
* projections
* approvals
* policies
* artifact definitions
* session fsm

must be:

* testable without IO
* replayable
* deterministic

2. application layer

contains:

* orchestration
* workflow execution
* context building
* retries
* scheduling
* coordination

this is the “brain”.

3. infrastructure layer

contains:

* sqlite
* llama.cpp
* shell
* websocket
* filesystem
* network

replaceable adapters only.

4. interface layer

contains:

* cli
* web api
* websocket protocol
* sdk

thin wrappers only.

most important subsystem boundaries

event system
source of truth.

projection system
derived/read models only.

transition engine
pure deterministic graph executor.

context processor
stateless synthesizer.

validation pipeline
hard gatekeeper.

approval engine
risk boundary.

tool runtime
isolated side effects.

model manager
resource scheduler.

router
human-facing facade only.

if implemented correctly, you should eventually be able to:

* replay entire sessions deterministically
* swap model providers without touching orchestration
* rebuild every projection from events
* run headless without UI
* replace frontend entirely
* distribute workers later
* test most logic without inference
* fuzz transitions/approvals safely

that’s usually the sign the boundaries are correct.
