-# Specification Mismatches
-
-## Scope
-Findings are mismatches between current repository source behavior and existing docs/spec pages under `docs/`.
-
-### 1) `docs/getting-started.md` uses deprecated constructor pattern
-- Example and prose show `core.New(core.Options{...})` and say constructor reads only the first `core.Options`.
-- Current code uses variadic `core.New(...CoreOption)` only; passing `core.Options` requires `core.WithOptions(core.NewOptions(...))`.
-- References: `docs/getting-started.md:18`, `docs/getting-started.md:26`, `docs/getting-started.md:142`.
-
-### 2) `docs/testing.md` and `docs/configuration.md` repeat outdated constructor usage
-- Both files document `core.New(core.Options{...})` examples.
-- Current constructor is variadic `CoreOption` values.
-- References: `docs/testing.md:29`, `docs/configuration.md:16`.
-
-### 3) `docs/lifecycle.md` claims registry order is map-backed and unstable
-- File states `Startables()/Stoppables()` are built from a map-backed registry and therefore non-deterministic.
-- Current `Registry` stores an explicit insertion-order slice and iterates in insertion order.
-- References: `docs/lifecycle.md:64-67`.
-
-### 4) `docs/services.md` stale ordering and lock-name behavior
-- Claims registry is map-backed; actual behavior is insertion-order iteration.
-- States default service lock name is `"srv"`, but `LockEnable`/`LockApply` do not expose/use a default namespace in implementation.
-- References: `docs/services.md:53`, `docs/services.md:86-88`.
-
-### 5) `docs/commands.md` documents removed managed lifecycle field
-- Section “Lifecycle Commands” shows `Lifecycle` field with `Start/Stop/Restart/Reload/Signal` callbacks.
-- Current `Command` struct has `Managed string` and no `Lifecycle` field.
-- References: `docs/commands.md:155-159`.
-
-### 6) `docs/subsystems.md` documents legacy options creation call for subsystem registration
-- Uses `c.Data().New(core.Options{...})` and `c.Drive().New(core.Options{...})`.
-- `Data.New` and `Drive.New` expect `core.Options` via varargs usage helpers (`core.NewOptions` in current docs/usage pattern).
-- References: `docs/subsystems.md:44`, `docs/subsystems.md:75`, `docs/subsystems.md:80`.
-
-### 7) `docs/index.md` RFC summary is stale
-- Claims `docs/RFC.md` is 21 sections, 1476 lines, but current RFC content has expanded sections/size.
-- Reference: `docs/index.md` table header note.

 - one input shape: `Options`
 - one output shape: `Result`

-- one permission gate: `Entitled`
-- one collection primitive: `Registry[T]`
+- one message bus: `ACTION`, `QUERY`, `PERFORM`
+
+## Why It Exists
+
+Most non-trivial Go systems end up needing the same small set of infrastructure:
+
+- a place to keep runtime state and shared subsystems
+- a predictable way to start and stop managed components
+- a clean command surface for CLI-style workflows
+- decoupled communication between components without tight imports
+
+CoreGO keeps those pieces small and explicit.

 # CoreGO
 
-CoreGO is the foundation layer for the Core ecosystem. Module: `dappco.re/go/core`.
+CoreGO is the foundation layer for the Core ecosystem. It gives you one container, one command tree, one message bus, and a small set of shared primitives that repeat across the whole framework.
 
-## What CoreGO Provides
+The current module path is `dappco.re/go/core`.
 
-| Primitive | Purpose |
-|-----------|---------|
-| `Core` | Central container — everything registers here |
-| `Service` | Lifecycle-managed component (Startable/Stoppable return Result) |
-| `Action` | Named callable with panic recovery + entitlement |
-| `Task` | Composed sequence of Actions |
-| `Registry[T]` | Thread-safe named collection (universal brick) |
-| `Command` | Path-based CLI command tree |
-| `Process` | Managed execution (Action sugar over go-process) |
-| `API` | Remote streams (protocol handlers + Drive) |
-| `Entitlement` | Permission gate (default permissive, consumer replaces) |
-| `ACTION`, `QUERY` | Anonymous broadcast + request/response |
-| `Data`, `Drive`, `Fs`, `Config`, `I18n` | Built-in subsystems |
+## AX View
+
+CoreGO already follows the main AX ideas from RFC-025:
+
+- predictable names such as `Core`, `Service`, `Command`, `Options`, `Result`, `Message`
+- path-shaped command registration such as `deploy/to/homelab`
+- one repeated input shape (`Options`) and one repeated return shape (`Result`)
+- comments and examples that show real usage instead of restating the type signature
+
+## What CoreGO Owns
+
+| Surface | Purpose |
+|---------|---------|
+| `Core` | Central container and access point |
+| `Service` | Managed lifecycle component |
+| `Command` | Path-based command tree node |
+| `ACTION`, `QUERY`, `PERFORM` | Decoupled communication between components |
+| `Data`, `Drive`, `Fs`, `Config`, `I18n`, `Cli` | Built-in subsystems for common runtime work |
+| `E`, `Wrap`, `ErrorLog`, `ErrorPanic` | Structured failures and panic recovery |
 
 ## Quick Example
 
 ```go
 package main
 
-import "dappco.re/go/core"
+import (
+	"context"
+	"fmt"
+
+	"dappco.re/go/core"

+}
 
 func main() {

-        core.WithOption("name", "agent-workbench"),
-        core.WithService(cache.Register),
-        core.WithServiceLock(),
-    )
-    c.Run()
+	c := core.New(core.Options{
+		{Key: "name", Value: "agent-workbench"},
+	})
+
+	c.Service("cache", core.Service{
+		OnStart: func() core.Result {
+			core.Info("cache ready", "app", c.App().Name)
+			return core.Result{OK: true}
+		},
+		OnStop: func() core.Result {
+			core.Info("cache stopped", "app", c.App().Name)
+			return core.Result{OK: true}
+		},
+	})
+
+	c.RegisterTask(func(_ *core.Core, task core.Task) core.Result {
+		switch task.(type) {
+		case flushCacheTask:
+			return core.Result{Value: "cache flushed", OK: true}
+		}
+		return core.Result{}
+	})
+
+	c.Command("cache/flush", core.Command{
+		Action: func(opts core.Options) core.Result {
+			return c.PERFORM(flushCacheTask{Name: opts.String("name")})
+		},
+	})
+
+	if !c.ServiceStartup(context.Background(), nil).OK {
+		panic("startup failed")
+	}
+
+	r := c.Cli().Run("cache", "flush", "--name=session-store")
+	fmt.Println(r.Value)

+	_ = c.ServiceShutdown(context.Background())

 # Messaging
 
-CoreGO has two messaging layers: anonymous broadcast (ACTION/QUERY) and named Actions.
+CoreGO uses one message bus for broadcasts, lookups, and work dispatch.
 
-## Anonymous Broadcast
+## Message Types
 
-### `ACTION`
+```go
+type Message any
+type Query any
+type Task any
+```
 
-Fire-and-forget broadcast to all registered handlers. Each handler is wrapped in panic recovery. Handler return values are ignored — all handlers fire regardless.
+Your own structs define the protocol.

+	Name string
+}
+
+type repositoryCountQuery struct{}
+
+type syncRepositoryTask struct {
+	Name string
+}
+```
+
+## `ACTION`
+
+`ACTION` is a broadcast.
 
 ```go
 c.RegisterAction(func(_ *core.Core, msg core.Message) core.Result {
-    if ev, ok := msg.(repositoryIndexed); ok {
-        core.Info("indexed", "name", ev.Name)
-    }
-    return core.Result{OK: true}
+	switch m := msg.(type) {
+	case repositoryIndexed:
+		core.Info("repository indexed", "name", m.Name)
+		return core.Result{OK: true}
+	}
+	return core.Result{OK: true}
 })
 
-c.ACTION(repositoryIndexed{Name: "core-go"})
+r := c.ACTION(repositoryIndexed{Name: "core-go"})
 ```
 
-### `QUERY`
+### Behavior
 
-First handler to return `OK:true` wins.
+- all registered action handlers are called in their current registration order
+- if a handler returns `OK:false`, dispatch stops and that `Result` is returned
+- if no handler fails, `ACTION` returns `Result{OK:true}`
+
+## `QUERY`
+
+`QUERY` is first-match request-response.
 
 ```go
 c.RegisterQuery(func(_ *core.Core, q core.Query) core.Result {
-    if _, ok := q.(repositoryCountQuery); ok {
-        return core.Result{Value: 42, OK: true}
-    }
-    return core.Result{}
+	switch q.(type) {
+	case repositoryCountQuery:
+		return core.Result{Value: 42, OK: true}
+	}
+	return core.Result{}
 })
 
 r := c.QUERY(repositoryCountQuery{})
 ```
 
-### `QUERYALL`
+### Behavior
 
-Collects every successful non-nil response.
+- handlers run until one returns `OK:true`
+- the first successful result wins
+- if nothing handles the query, CoreGO returns an empty `Result`
+
+## `QUERYALL`
+
+`QUERYALL` collects every successful non-nil response.
 
 ```go
 r := c.QUERYALL(repositoryCountQuery{})
 results := r.Value.([]any)
 ```
 
-## Named Actions
+### Behavior
 
-Named Actions are the typed, inspectable replacement for anonymous dispatch. See Section 18 of `RFC.md`.
+- every query handler is called
+- only `OK:true` results with non-nil `Value` are collected
+- the call itself returns `OK:true` even when the result list is empty
 
-### Register and Invoke
+## `PERFORM`
+
+`PERFORM` dispatches a task to the first handler that accepts it.
 
 ```go
-// Register during OnStartup
-c.Action("repo.sync", func(ctx context.Context, opts core.Options) core.Result {
-    name := opts.String("name")
-    return core.Result{Value: "synced " + name, OK: true}
+c.RegisterTask(func(_ *core.Core, t core.Task) core.Result {
+	switch task := t.(type) {
+	case syncRepositoryTask:
+		return core.Result{Value: "synced " + task.Name, OK: true}
+	}
+	return core.Result{}
 })
 
-// Invoke by name
-r := c.Action("repo.sync").Run(ctx, core.NewOptions(
-    core.Option{Key: "name", Value: "core-go"},
-))
+r := c.PERFORM(syncRepositoryTask{Name: "core-go"})
 ```
 
-### Capability Check
+### Behavior
+
+- handlers run until one returns `OK:true`
+- the first successful result wins
+- if nothing handles the task, CoreGO returns an empty `Result`
+
+## `PerformAsync`
+
+`PerformAsync` runs a task in a background goroutine and returns a generated task identifier.
 
 ```go
-if c.Action("process.run").Exists() {
-    // go-process is registered
-}
-
-c.Actions()  // []string of all registered action names
-```
-
-### Permission Gate
-
-Every `Action.Run()` checks `c.Entitled(action.Name)` before executing. See Section 21 of `RFC.md`.
-
-## Task Composition
-
-A Task is a named sequence of Actions:
-
-```go
-c.Task("deploy", core.Task{
-    Steps: []core.Step{
-        {Action: "go.build"},
-        {Action: "go.test"},
-        {Action: "docker.push"},
-        {Action: "notify.slack", Async: true},
-    },
-})
-
-r := c.Task("deploy").Run(ctx, c, opts)
-```
-
-Sequential steps stop on first failure. `Async: true` steps fire without blocking. `Input: "previous"` pipes output.
-
-## Background Execution
-
-```go
-r := c.PerformAsync("repo.sync", opts)
+r := c.PerformAsync(syncRepositoryTask{Name: "core-go"})
 taskID := r.Value.(string)
-
-c.Progress(taskID, 0.5, "indexing commits", "repo.sync")
 ```
 
-Broadcasts `ActionTaskStarted`, `ActionTaskProgress`, `ActionTaskCompleted` as ACTION messages.
+### Generated Events
 
-### Completion Listener
+Async execution emits three action messages:
+
+| Message | When |
+|---------|------|
+| `ActionTaskStarted` | just before background execution begins |
+| `ActionTaskProgress` | whenever `Progress` is called |
+| `ActionTaskCompleted` | after the task finishes or panics |
+
+Example listener:
 
 ```go
 c.RegisterAction(func(_ *core.Core, msg core.Message) core.Result {
-    if ev, ok := msg.(core.ActionTaskCompleted); ok {
-        core.Info("done", "task", ev.TaskIdentifier, "ok", ev.Result.OK)
-    }
-    return core.Result{OK: true}
+	switch m := msg.(type) {
+	case core.ActionTaskCompleted:
+		core.Info("task completed", "task", m.TaskIdentifier, "err", m.Error)
+	}
+	return core.Result{OK: true}
 })
 ```
 
-## Shutdown
+## Progress Updates
 
-When shutdown has started, `PerformAsync` returns an empty `Result`. `ServiceShutdown` drains outstanding background work before stopping services.
+```go
+c.Progress(taskID, 0.5, "indexing commits", syncRepositoryTask{Name: "core-go"})
+```
+
+That broadcasts `ActionTaskProgress`.
+
+## `TaskWithIdentifier`
+
+Tasks that implement `TaskWithIdentifier` receive the generated ID before dispatch.
+
+```go
+type trackedTask struct {
+	ID   string
+	Name string
+}
+
+func (t *trackedTask) SetTaskIdentifier(id string) { t.ID = id }
+func (t *trackedTask) GetTaskIdentifier() string   { return t.ID }
+```
+
+## Shutdown Interaction
+
+When shutdown has started, `PerformAsync` returns an empty `Result` instead of scheduling more work.
+
+This is why `ServiceShutdown` can safely drain the outstanding background tasks before stopping services.

 # Core Primitives
 
-CoreGO is built from a small vocabulary repeated everywhere.
+CoreGO is easiest to use when you read it as a small vocabulary repeated everywhere. Most of the framework is built from the same handful of types.
 
 ## Primitive Map
 
 | Type | Used For |
 |------|----------|
-| `Option` / `Options` | Input values and metadata |
+| `Options` | Input values and lightweight metadata |
 | `Result` | Output values and success state |
 | `Service` | Lifecycle-managed components |
-| `Action` | Named callable with panic recovery + entitlement |
-| `Task` | Composed sequence of Actions |
-| `Registry[T]` | Thread-safe named collection |
-| `Entitlement` | Permission check result |
-| `Message` | Broadcast events (ACTION) |
-| `Query` | Request-response lookups (QUERY) |
+| `Message` | Broadcast events |
+| `Query` | Request-response lookups |
+| `Task` | Side-effecting work items |
 
 ## `Option` and `Options`
 
 `Option` is one key-value pair. `Options` is an ordered slice of them.
 
 ```go
-opts := core.NewOptions(
-    core.Option{Key: "name", Value: "brain"},
-    core.Option{Key: "path", Value: "prompts"},
-    core.Option{Key: "debug", Value: true},
-)
-
-name := opts.String("name")
-debug := opts.Bool("debug")
-raw := opts.Get("name")     // Result{Value, OK}
-opts.Has("path")             // true
-opts.Len()                   // 3
+opts := core.Options{
+	{Key: "name", Value: "brain"},
+	{Key: "path", Value: "prompts"},
+	{Key: "debug", Value: true},
+}
 ```
 
+Use the helpers to read values:
+
+```go
+name := opts.String("name")
+path := opts.String("path")
+debug := opts.Bool("debug")
+hasPath := opts.Has("path")
+raw := opts.Get("name")
+```
+
+### Important Details
+
+- `Get` returns the first matching key.
+- `String`, `Int`, and `Bool` do not convert between types.
+- Missing keys return zero values.
+- CLI flags with values are stored as strings, so `--port=8080` should be read with `opts.String("port")`, not `opts.Int("port")`.
+
 ## `Result`
 
-Universal return shape. Every Core operation returns Result.
+`Result` is the universal return shape.
 
 ```go
-type Result struct {
-    Value any
-    OK    bool
-}
+r := core.Result{Value: "ready", OK: true}
 
-r := c.Config().Get("host")
 if r.OK {
-    host := r.Value.(string)
+	fmt.Println(r.Value)
 }
 ```
 
-The `Result()` method adapts Go `(value, error)` pairs:
+It has two jobs:
+
+- carry a value when work succeeds
+- carry either an error or an empty state when work does not succeed
+
+### `Result.Result(...)`
+
+The `Result()` method adapts plain Go values and `(value, error)` pairs into a `core.Result`.
 
 ```go
-r := core.Result{}.Result(file, err)
+r1 := core.Result{}.Result("hello")
+r2 := core.Result{}.Result(file, err)
 ```
 
+This is how several built-in helpers bridge standard-library calls.
+
 ## `Service`
 
-Managed lifecycle component stored in the `ServiceRegistry`.
+`Service` is the managed lifecycle DTO stored in the registry.
 
 ```go
-core.Service{
-    OnStart: func() core.Result { return core.Result{OK: true} },
-    OnStop:  func() core.Result { return core.Result{OK: true} },
+svc := core.Service{
+	Name: "cache",
+	Options: core.Options{
+		{Key: "backend", Value: "memory"},
+	},
+	OnStart: func() core.Result {
+		return core.Result{OK: true}
+	},
+	OnStop: func() core.Result {
+		return core.Result{OK: true}
+	},
+	OnReload: func() core.Result {
+		return core.Result{OK: true}
+	},
 }
 ```
 
-Or via `Startable`/`Stoppable` interfaces (preferred for named services):
+### Important Details
+
+- `OnStart` and `OnStop` are used by the framework lifecycle.
+- `OnReload` is stored on the service DTO, but CoreGO does not currently call it automatically.
+- The registry stores `*core.Service`, not arbitrary typed service instances.
+
+## `Message`, `Query`, and `Task`
+
+These are simple aliases to `any`.
 
 ```go
-type Startable interface { OnStartup(ctx context.Context) Result }
-type Stoppable interface { OnShutdown(ctx context.Context) Result }
+type Message any
+type Query any
+type Task any
 ```
 
-## `Action`
-
-Named callable — the atomic unit of work. Registered by name, invoked by name.
+That means your own structs become the protocol:
 
 ```go
-type ActionHandler func(context.Context, Options) Result
+type deployStarted struct {
+	Environment string
+}
 
-type Action struct {
-    Name        string
-    Handler     ActionHandler
-    Description string
-    Schema      Options
+type workspaceCountQuery struct{}
+
+type syncRepositoryTask struct {
+	Name string
 }
 ```
 
-`Action.Run()` includes panic recovery and entitlement checking.
+## `TaskWithIdentifier`
 
-## `Task`
-
-Composed sequence of Actions:
+Long-running tasks can opt into task identifiers.
 
 ```go
-type Task struct {
-    Name        string
-    Description string
-    Steps       []Step
+type indexedTask struct {
+	ID string
 }
 
-type Step struct {
-    Action string
-    With   Options
-    Async  bool
-    Input  string   // "previous" = output of last step
-}
+func (t *indexedTask) SetTaskIdentifier(id string) { t.ID = id }
+func (t *indexedTask) GetTaskIdentifier() string   { return t.ID }
 ```
 
-## `Registry[T]`
-
-Thread-safe named collection with insertion order and 3 lock modes:
-
-```go
-r := core.NewRegistry[*MyService]()
-r.Set("brain", svc)
-r.Get("brain")       // Result
-r.Has("brain")       // bool
-r.Names()            // []string (insertion order)
-r.Each(func(name string, svc *MyService) { ... })
-r.Lock()             // fully frozen
-r.Seal()             // no new keys, updates OK
-```
-
-## `Entitlement`
-
-Permission check result:
-
-```go
-type Entitlement struct {
-    Allowed   bool
-    Unlimited bool
-    Limit     int
-    Used      int
-    Remaining int
-    Reason    string
-}
-
-e := c.Entitled("social.accounts", 3)
-e.NearLimit(0.8)     // true if > 80% used
-e.UsagePercent()     // 75.0
-```
-
-## `Message` and `Query`
-
-IPC type aliases for the anonymous broadcast system:
-
-```go
-type Message any  // broadcast via ACTION
-type Query any    // request/response via QUERY
-```
-
-For typed, named dispatch use `c.Action("name").Run(ctx, opts)`.
+If a task implements `TaskWithIdentifier`, `PerformAsync` injects the generated `task-N` identifier before dispatch.
 
 ## `ServiceRuntime[T]`
 
-Composition helper for services that need Core access and typed options:
+`ServiceRuntime[T]` is the small helper for packages that want to keep a Core reference and a typed options struct together.
 
 ```go
-type MyService struct {
-    *core.ServiceRuntime[MyOptions]
+type agentServiceOptions struct {
+	WorkspacePath string
 }
 
-runtime := core.NewServiceRuntime(c, MyOptions{BufferSize: 1024})
-runtime.Core()      // *Core
-runtime.Options()   // MyOptions
-runtime.Config()    // shortcut to Core().Config()
+type agentService struct {
+	*core.ServiceRuntime[agentServiceOptions]
+}
+
+runtime := core.NewServiceRuntime(c, agentServiceOptions{
+	WorkspacePath: "/srv/agent-workspaces",
+})
 ```
+
+It exposes:
+
+- `Core()`
+- `Options()`
+- `Config()`
+
+This helper does not register anything by itself. It is a composition aid for package authors.

-# core/go — CoreGO Framework
-
-> dappco.re/go/core — Dependency injection, service lifecycle, permission,
-> and message-passing framework for Go. Foundation layer for the Lethean ecosystem.
-
-## Entry Points
-
-- CLAUDE.md — Agent instructions, build commands, subsystem table
-- docs/RFC.md — API contract specification (21 sections, the authoritative spec)
-
-## Package Layout
-
-All source files at module root. No pkg/ nesting. Tests are *_test.go alongside source.
-
-## Key Types
-
-- Core — Central application container (core.New() returns *Core)
-- Option — Single key-value pair {Key: string, Value: any}
-- Options — Collection of Option with typed accessors
-- Result — Universal return type {Value: any, OK: bool}
-- Service — Managed component with lifecycle (Startable/Stoppable return Result)
-- Action — Named callable with panic recovery and entitlement enforcement
-- Task — Composed sequence of Actions (Steps, Async, Input piping)
-- Registry[T] — Thread-safe named collection (universal brick)
-- Process — Managed execution (sugar over Actions)
-- API — Remote streams (protocol handlers, Drive integration)
-- Entitlement — Permission check result (Allowed, Limit, Used, Remaining)
-- Message — IPC broadcast type for ACTION
-- Query — IPC request/response type for QUERY
-
-## Service Pattern
-
-    core.New(
-        core.WithService(mypackage.Register),
-    )
-
-    func Register(c *core.Core) core.Result {
-        svc := &MyService{ServiceRuntime: core.NewServiceRuntime(c, opts)}
-        return core.Result{Value: svc, OK: true}
-    }
-
-## Conventions
-
-Follows RFC-025 Agent Experience (AX) principles.
-Tests: TestFile_Function_{Good,Bad,Ugly} — 100% AX-7 naming.
