Slice breakdown

This page is the map — a reference: every group, every sub-slice, one line each. The rules that decide why a slice sits where it sits are in Layered slices; pages that go deep on a subsystem are linked from its group.

infra — adapters (L0)

slice	what
prisma	Postgres client + per-slice .prisma assembly (#prisma)
redis	cache + BullMQ broker + pub/sub + locks
storage	object store (S3 / R2 / Hetzner OS) behind IStorageGateway
vector	vector store behind IVectorGateway (may dissolve into Postgres via LightRAG/pgvector)

setup — framework / exposure (L0)

slice	what
core	config, decorators, interceptors, BaseError, health, rate-limit
mcp	MCP server: @Tool/@Resource registry + SSE/HTTP/stdio transports (auth injected)

system — shared services (L1)

slice	sub-slices / purpose
usage	meter · aggregate · report — BillingEvent ledger
setting	limit · quota · enforcement · preference
notification	email · inApp · webhook · template
llm	gateway · toolAnalysis · embeddings (Claude)
file	store / sign / metadata / ownership over infra/storage (absorbed runtime artifacts)

user — identity / tenancy (L2)

The tenant is the team.

slice	what
user	person account, profile
team	tenant/org; owns agents, subscription, keys
userTeam	membership + role on a specific team
role	RBAC (owner/admin/member)
apiKey	programmatic keys, scoped to a team
auth	own JWT (issuer = Core), refresh, password/verify; mints runtime session tokens
invite	team invitations

admin — ops / audit (L3)

slice	what
admin	admin operations over tenant data (reads via Prisma)
audit	audit log (runtime sessions + privileged actions)
featureFlag	flags

runtime — execution pipeline (L4)

→ deep dive: Runtime model · Worker

slice	what
tasks	AgentTask queue on BullMQ (producer / worker / scheduled)
worker*	runtime-session manager: sessions · k8s · browser · idle · profiles
events	SSE/WS stream of logs+events via Redis pub/sub

* rename pending — avoid the clash with the worker app (the worker image).

agent — domain + brain (L5)

→ deep dives: Agent · Chat · Knowledge

slice	sub-slices / purpose
agent	definition: systemPrompt, tools, memoryConfig, runtimeProfile, status
memory	long-term agent memory over a vector store
knowledge	thin gateway to the LightRAG service
chat	thread · message · snapshot · attachment · insight · summary
app	connector · account · oauth · cookie · catalog (external integrations)
channel	channel · telegram · slack · widget
orchestrator	the brain: handler (intake/routing) · mode (runtime-mode selection)

billing — top sink (L6)

slice	what
subscription	team's active plan
product · price	catalog + prices (monthly / annual / usage)
paymentMethod	stored cards / instruments
invoice · payment	invoices (PDF) + transactions
webhook	payment-provider event intake
