 - Use Bun APIs when possible, like `Bun.file()`
 - Rely on type inference when possible; avoid explicit type annotations or interfaces unless necessary for exports or clarity
 - Prefer functional array methods (flatMap, filter, map) over for loops; use type guards on filter to maintain type inference downstream

+# Module shape
+
+Do not use `export namespace Foo { ... }` for module organization. It is not
+standard ESM, it prevents tree-shaking, and it breaks Node's native TypeScript
+runner. Use flat top-level exports combined with a self-reexport at the bottom
+of the file:
+
+```ts
+// src/foo/foo.ts
+export interface Interface { ... }
+export class Service extends Context.Service<Service, Interface>()("@opencode/Foo") {}
+export const layer = Layer.effect(Service, ...)
+export const defaultLayer = layer.pipe(...)
+
+export * as Foo from "./foo"
+```
+
+Consumers import the namespace projection:
+
+```ts
+import { Foo } from "@/foo/foo"
+
+yield * Foo.Service
+Foo.layer
+Foo.defaultLayer
+```
+
+Namespace-private helpers stay as non-exported top-level declarations in the
+same file — they remain inaccessible to consumers (they are not projected by
+`export * as`) but are usable by the file's own code.
+
+## When the file is an `index.ts`
+
+If the module is `foo/index.ts` (single-namespace directory), use `"."` for
+the self-reexport source rather than `"./index"`:
+
+```ts
+// src/foo/index.ts
+export const thing = ...
+
+export * as Foo from "."
+```
+
+## Multi-sibling directories
+
+For directories with several independent modules (e.g. `src/session/`,
+`src/config/`), keep each sibling as its own file with its own self-reexport,
+and do not add a barrel `index.ts`. Consumers import the specific sibling:
+
+```ts
+import { SessionRetry } from "@/session/retry"
+import { SessionStatus } from "@/session/status"
+```
+
+Barrels in multi-sibling directories force every import through the barrel to
+evaluate every sibling, which defeats tree-shaking and slows module load.

 # opencode Effect rules

 ## Schemas and errors

@@ -39,6 +100,12 @@ See `specs/effect/migration.md` for the compact pattern reference and examples.
 - Do the work directly in the `InstanceState.make` closure — `ScopedCache` handles run-once semantics. Don't add fibers, `ensure()` callbacks, or `started` flags on top.
 - Use `Effect.addFinalizer` or `Effect.acquireRelease` inside the `InstanceState.make` closure for cleanup (subscriptions, process teardown, etc.).
 - Use `Effect.forkScoped` inside the closure for background stream consumers — the fiber is interrupted when the instance is disposed.
+- To make a service's `init()` non-blocking, fork `InstanceState.get(state)` at the `init()` call site (e.g. `Effect.forkIn(scope)`), not by forking work inside the `InstanceState.make` closure. Forking inside the closure leaves state incomplete for other methods that read it.
+- `src/project/bootstrap.ts` already wraps every service `init()` in `Effect.forkDetach`, so `init()` is fire-and-forget in production. Keep `init()` methods synchronous internally; the caller controls concurrency.
+
+## Effect v4 beta API
+
+- `Effect.fork` and `Effect.forkDaemon` do not exist. Use `Effect.forkIn(scope)` to fork a fiber into a specific scope.

-# Namespace → flat export migration
-
-Migrate `export namespace` to the `export * as` / flat-export pattern used by
-effect-smol. Primary goal: tree-shakeability. Secondary: consistency with Effect
-conventions, LLM-friendliness for future migrations.
-
-## What changes and what doesn't
-
-The **consumer API stays the same**. You still write `Provider.ModelNotFoundError`,
-`Config.JsonError`, `Bus.publish`, etc. The namespace ergonomics are preserved.
-
-What changes is **how** the namespace is constructed — the TypeScript
-`export namespace` keyword is replaced by `export * as` in a barrel file. This
-is a mechanical change: unwrap the namespace body into flat exports, add a
-one-line barrel. Consumers that import `{ Provider }` don't notice.
-
-Import paths actually get **nicer**. Today most consumers import from the
-explicit file (`"../provider/provider"`). After the migration, each module has a
-barrel `index.ts`, so imports become `"../provider"` or `"@/provider"`:
-
-```ts
-// BEFORE — points at the file directly
-import { Provider } from "../provider/provider"
-
-// AFTER — resolves to provider/index.ts, same Provider namespace
-import { Provider } from "../provider"
-```
-
-## Why this matters right now
-
-The CLI binary startup time (TOI) is too slow. Profiling shows we're loading
-massive dependency graphs that are never actually used at runtime — because
-bundlers cannot tree-shake TypeScript `export namespace` bodies.
-
-### The problem in one sentence
-
-`cli/error.ts` needs 6 lightweight `.isInstance()` checks on error classes, but
-importing `{ Provider }` from `provider.ts` forces the bundler to include **all
-20+ `@ai-sdk/*` packages**, `@aws-sdk/credential-providers`,
-`google-auth-library`, and every other top-level import in that 1709-line file.
-
-### Why `export namespace` defeats tree-shaking
-
-TypeScript compiles `export namespace Foo { ... }` to an IIFE:
-
-```js
-// TypeScript output
-export var Provider;
-(function (Provider) {
-  Provider.ModelNotFoundError = NamedError.create(...)
-  // ... 1600 more lines of assignments ...
-})(Provider || (Provider = {}))
-```
-
-This is **opaque to static analysis**. The bundler sees one big function call
-whose return value populates an object. It cannot determine which properties are
-used downstream, so it keeps everything. Every `import` statement at the top of
-`provider.ts` executes unconditionally — that's 20+ AI SDK packages loaded into
-memory just so the CLI can check `Provider.ModelNotFoundError.isInstance(x)`.
-
-### What `export * as` does differently
-
-`export * as Provider from "./provider"` compiles to a static re-export. The
-bundler knows the exact shape of `Provider` at compile time — it's the named
-export list of `./provider.ts`. When it sees `Provider.ModelNotFoundError` used
-but `Provider.layer` unused, it can trace that `ModelNotFoundError` doesn't
-reference `createAnthropic` or any AI SDK import, and drop them. The namespace
-object still exists at runtime — same API — but the bundler can see inside it.
-
-### Concrete impact
-
-The worst import chain in the codebase:
-
-```
-src/index.ts (entry point)
-  └── FormatError from src/cli/error.ts
-        ├── { Provider } from provider/provider.ts     (1709 lines)
-        │     ├── 20+ @ai-sdk/* packages
-        │     ├── @aws-sdk/credential-providers
-        │     ├── google-auth-library
-        │     ├── gitlab-ai-provider, venice-ai-sdk-provider
-        │     └── fuzzysort, remeda, etc.
-        ├── { Config } from config/config.ts           (1663 lines)
-        │     ├── jsonc-parser
-        │     ├── LSPServer (all server definitions)
-        │     └── Plugin, Auth, Env, Account, etc.
-        └── { MCP } from mcp/index.ts                  (930 lines)
-              ├── @modelcontextprotocol/sdk (3 transports)
-              └── open (browser launcher)
-```
-
-All of this gets pulled in to check `.isInstance()` on 6 error classes — code
-that needs maybe 200 bytes total. This inflates the binary, increases startup
-memory, and slows down initial module evaluation.
-
-### Why this also hurts memory
-
-Every module-level import is eagerly evaluated. Even with Bun's fast module
-loader, evaluating 20+ AI SDK factory functions, the AWS credential chain, and
-Google's auth library allocates objects, closures, and prototype chains that
-persist for the lifetime of the process. Most CLI commands never use a provider
-at all.
-
-## What effect-smol does
-
-effect-smol achieves tree-shakeable namespaced APIs via three structural choices.
-
-### 1. Each module is a separate file with flat named exports
-
-```ts
-// Effect.ts — no namespace wrapper, just flat exports
-export const gen: { ... } = internal.gen
-export const fail: <E>(error: E) => Effect<never, E> = internal.fail
-export const succeed: <A>(value: A) => Effect<A> = internal.succeed
-// ... 230+ individual named exports
-```
-
-### 2. Barrel file uses `export * as` (not `export namespace`)
-
-```ts
-// index.ts
-export * as Effect from "./Effect.ts"
-export * as Schema from "./Schema.ts"
-export * as Stream from "./Stream.ts"
-// ~134 modules
-```
-
-This creates a namespace-like API (`Effect.gen`, `Schema.parse`) but the
-bundler knows the **exact shape** at compile time — it's the static export list
-of that file. It can trace property accesses (`Effect.gen` → keep `gen`,
-drop `timeout` if unused). With `export namespace`, the IIFE is opaque and
-nothing can be dropped.
-
-### 3. `sideEffects: []` and deep imports
-
-```jsonc
-// package.json
-{ "sideEffects": [] }
-```
-
-Plus `"./*": "./src/*.ts"` in the exports map, enabling
-`import * as Effect from "effect/Effect"` to bypass the barrel entirely.
-
-### 4. Errors as flat exports, not class declarations
-
-```ts
-// Cause.ts
-export const NoSuchElementErrorTypeId = core.NoSuchElementErrorTypeId
-export interface NoSuchElementError extends YieldableError { ... }
-export const NoSuchElementError: new(msg?: string) => NoSuchElementError = core.NoSuchElementError
-export const isNoSuchElementError: (u: unknown) => u is NoSuchElementError = core.isNoSuchElementError
-```
-
-Each error is 4 independent exports: TypeId, interface, constructor (as const),
-type guard. All individually shakeable.
-
-## The plan
-
-The core migration is **Phase 1** — convert `export namespace` to
-`export * as`. Once that's done, the bundler can tree-shake individual exports
-within each module. You do NOT need to break things into subfiles for
-tree-shaking to work — the bundler traces which exports you actually access on
-the namespace object and drops the rest, including their transitive imports.
-
-Splitting errors/schemas into separate files (Phase 0) is optional — it's a
-lower-risk warmup step that can be done before or after the main conversion, and
-it provides extra resilience against bundler edge cases. But the big win comes
-from Phase 1.
-
-### Phase 0 (optional): Pre-split errors into subfiles
-
-This is a low-risk warmup that provides immediate benefit even before the full
-`export * as` conversion. It's optional because Phase 1 alone is sufficient for
-tree-shaking. But it's a good starting point if you want incremental progress:
-
-**For each namespace that defines errors** (15 files, ~30 error classes total):
-
-1. Create a sibling `errors.ts` file (e.g. `provider/errors.ts`) with the error
-   definitions as top-level named exports:
-
-   ```ts
-   // provider/errors.ts
-   import z from "zod"
-   import { NamedError } from "@opencode-ai/shared/util/error"
-   import { ProviderID, ModelID } from "./schema"
-
-   export const ModelNotFoundError = NamedError.create(
-     "ProviderModelNotFoundError",
-     z.object({
-       providerID: ProviderID.zod,
-       modelID: ModelID.zod,
-       suggestions: z.array(z.string()).optional(),
-     }),
-   )
-
-   export const InitError = NamedError.create("ProviderInitError", z.object({ providerID: ProviderID.zod }))
-   ```
-
-2. In the namespace file, re-export from the errors file to maintain backward
-   compatibility:
-
-   ```ts
-   // provider/provider.ts — inside the namespace
-   export { ModelNotFoundError, InitError } from "./errors"
-   ```
-
-3. Update `cli/error.ts` (and any other light consumers) to import directly:
-
-   ```ts
-   // BEFORE
-   import { Provider } from "../provider/provider"
-   Provider.ModelNotFoundError.isInstance(input)
-
-   // AFTER
-   import { ModelNotFoundError as ProviderModelNotFoundError } from "../provider/errors"
-   ProviderModelNotFoundError.isInstance(input)
-   ```
-
-**Files to split (Phase 0):**
-
-| Current file            | New errors file                 | Errors to extract                                                                                                       |

-### Phase 1: The real migration — `export namespace` → `export * as`
-
-This is the phase that actually fixes tree-shaking. For each module:
-
-1. **Unwrap** the `export namespace Foo { ... }` — remove the namespace wrapper,
-   keep all the members as top-level `export const` / `export function` / etc.
-2. **Rename** the file if it's currently `index.ts` (e.g. `bus/index.ts` →
-   `bus/bus.ts`), so the barrel can take `index.ts`.
-3. **Create the barrel** `index.ts` with one line: `export * as Foo from "./foo"`
-
-The file structure change for a module that's currently a single file:
-
-```
-# BEFORE
-provider/
-  provider.ts        ← 1709-line file with `export namespace Provider { ... }`
-
-# AFTER
-provider/
-  index.ts           ← NEW: `export * as Provider from "./provider"`
-  provider.ts        ← SAME file, same name, just unwrap the namespace
-```
-
-And the code change is purely removing the wrapper:
-
-```ts
-// BEFORE: provider/provider.ts
-export namespace Provider {
-  export class Service extends Context.Service<...>()("@opencode/Provider") {}
-  export const layer = Layer.effect(Service, ...)
-  export const ModelNotFoundError = NamedError.create(...)
-  export function parseModel(model: string) { ... }
-}
-
-// AFTER: provider/provider.ts — identical exports, no namespace keyword
-export class Service extends Context.Service<...>()("@opencode/Provider") {}
-export const layer = Layer.effect(Service, ...)
-export const ModelNotFoundError = NamedError.create(...)
-export function parseModel(model: string) { ... }
-```
-
-```ts
-// NEW: provider/index.ts
-export * as Provider from "./provider"
-```
-
-Consumer code barely changes — import path gets shorter:
-
-```ts
-// BEFORE
-import { Provider } from "../provider/provider"
-
-// AFTER — resolves to provider/index.ts, same Provider object
-import { Provider } from "../provider"
-```
-
-All access like `Provider.ModelNotFoundError`, `Provider.Service`,
-`Provider.layer` works exactly as before. The difference is invisible to
-consumers but lets the bundler see inside the namespace.
-
-**Once this is done, you don't need to break anything into subfiles for
-tree-shaking.** The bundler traces that `Provider.ModelNotFoundError` only
-depends on `NamedError` + `zod` + the schema file, and drops
-`Provider.layer` + all 20 AI SDK imports when they're unused. This works because
-`export * as` gives the bundler a static export list it can do inner-graph
-analysis on — it knows which exports reference which imports.
-
-**Order of conversion** (by risk / size, do small modules first):
-
-1. Tiny utilities: `Archive`, `Color`, `Token`, `Rpc`, `LocalContext` (~7-66 lines each)
-2. Small services: `Auth`, `Env`, `BusEvent`, `SessionStatus`, `SessionRunState`, `Editor`, `Selection` (~25-91 lines)
-3. Medium services: `Bus`, `Format`, `FileTime`, `FileWatcher`, `Command`, `Question`, `Permission`, `Vcs`, `Project`
-4. Large services: `Config`, `Provider`, `MCP`, `Session`, `SessionProcessor`, `SessionPrompt`, `ACP`
-
-### Phase 2: Build configuration
-
-After the module structure supports tree-shaking:
-
-1. Add `"sideEffects": []` to `packages/opencode/package.json` (or
-   `"sideEffects": false`) — this is safe because our services use explicit
-   layer composition, not import-time side effects.
-2. Verify Bun's bundler respects the new structure. If Bun's tree-shaking is
-   insufficient, evaluate whether the compiled binary path needs an esbuild
-   pre-pass.
-3. Consider adding `/*#__PURE__*/` annotations to `NamedError.create(...)` calls
-   — these are factory functions that return classes, and bundlers may not know
-   they're side-effect-free without the annotation.
-
-## Automation
-
-The transformation is scripted. From `packages/opencode`:
-
-```bash
-bun script/unwrap-namespace.ts <file> [--dry-run]
-```
-
-The script uses ast-grep for accurate AST-based namespace boundary detection
-(no false matches from braces in strings/templates/comments), then:
-
-1. Removes the `export namespace Foo {` line and its closing `}`
-2. Dedents the body by one indent level (2 spaces)
-3. If the file is `index.ts`, renames it to `<name>.ts` and creates a new
-   `index.ts` barrel
-4. If the file is NOT `index.ts`, rewrites it in place and creates `index.ts`
-5. Prints the exact commands to find and rewrite import paths
-
-### Walkthrough: converting a module
-
-Using `Provider` as an example:
-
-```bash
-# 1. Preview what will change
-bun script/unwrap-namespace.ts src/provider/provider.ts --dry-run
-
-# 2. Apply the transformation
-bun script/unwrap-namespace.ts src/provider/provider.ts
-
-# 3. Rewrite import paths (script prints the exact command)
-rg -l 'from.*provider/provider' src/ | xargs sed -i '' 's|provider/provider"|provider"|g'
-
-# 4. Verify
-bun typecheck
-bun run test
-```
-
-**What changes on disk:**
-
-```
-# BEFORE
-provider/
-  provider.ts        ← 1709 lines, `export namespace Provider { ... }`
-
-# AFTER
-provider/
-  index.ts           ← NEW: `export * as Provider from "./provider"`
-  provider.ts        ← same file, namespace unwrapped to flat exports
-```
-
-**What changes in consumer code:**
-
-```ts
-// BEFORE
-import { Provider } from "../provider/provider"
-
-// AFTER — shorter path, same Provider object
-import { Provider } from "../provider"
-```
-
-All property access (`Provider.Service`, `Provider.ModelNotFoundError`, etc.)
-stays identical.
-
-### Two cases the script handles
-
-**Case A: file is NOT `index.ts`** (e.g. `provider/provider.ts`)
-
- Rewrites the file in place (unwrap + dedent)
- Creates `provider/index.ts` as the barrel
- Import paths change: `"../provider/provider"` → `"../provider"`
-
-**Case B: file IS `index.ts`** (e.g. `bus/index.ts`)
-
- Renames `index.ts` → `bus.ts` (kebab-case of namespace name)
- Creates new `index.ts` as the barrel
- **No import rewrites needed** — `"@/bus"` already resolves to `bus/index.ts`
-
-## Do I need to split errors/schemas into subfiles?
-
-**No.** Once you do the `export * as` conversion, the bundler can tree-shake
-individual exports within the file. If `cli/error.ts` only accesses
-`Provider.ModelNotFoundError`, the bundler traces that `ModelNotFoundError`
-doesn't reference `createAnthropic` and drops the AI SDK imports.
-
-Splitting into subfiles (errors.ts, schema.ts) is still a fine idea for **code
-organization** — smaller files are easier to read and review. But it's not
-required for tree-shaking. The `export * as` conversion alone is sufficient.
-
-The one case where subfile splitting provides extra tree-shake value is if an
-imported package has module-level side effects that the bundler can't prove are
-unused. In practice this is rare — most npm packages are side-effect-free — and
-adding `"sideEffects": []` to package.json handles the common cases.
-
-## Scope
-
-| Metric                                          | Count           |
-| ----------------------------------------------- | --------------- |
-| Files with `export namespace`                   | 106             |
-| Total namespace declarations                    | 118 (12 nested) |
-| Files with `NamedError.create` inside namespace | 15              |
-| Total error classes to extract                  | ~30             |
-| Files using `export * as` today                 | 0               |
-
-Phase 1 (the `export * as` conversion) is the main change. It's mechanical and
-LLM-friendly but touches every import site, so it should be done module by
-module with type-checking between each step. Each module is an independent PR.
-
-## Rules for new code
-
-Going forward:
-
- **No new `export namespace`**. Use a file with flat named exports and
-  `export * as` in the barrel.
- Keep the service, layer, errors, schemas, and runtime wiring together in one
-  file if you want — that's fine now. The `export * as` barrel makes everything
-  individually shakeable regardless of file structure.
- If a file grows large enough that it's hard to navigate, split by concern
-  (errors.ts, schema.ts, etc.) for readability. Not for tree-shaking — the
-  bundler handles that.
