 /**
- * Unwrap a TypeScript `export namespace` into flat exports + barrel.
+ * Unwrap a TypeScript `export namespace` into flat exports with self-reexport.
  *
  * Usage:
- *   bun script/unwrap-namespace.ts src/bus/index.ts
- *   bun script/unwrap-namespace.ts src/bus/index.ts --dry-run
- *   bun script/unwrap-namespace.ts src/pty/index.ts --name service   # avoid collision with pty.ts
+ *   bun script/unwrap-namespace.ts src/session/session.ts           # convert namespace
+ *   bun script/unwrap-namespace.ts src/session/session.ts --dry-run
+ *   bun script/unwrap-namespace.ts src/pty/index.ts --name service  # avoid filename collision
+ *   bun script/unwrap-namespace.ts src/config/config.ts --retrofit  # already flat, add self-reexport
  *
- * What it does:
- *   1. Reads the file and finds the `export namespace Foo { ... }` block
- *      (uses ast-grep for accurate AST-based boundary detection)
- *   2. Removes the namespace wrapper and dedents the body
- *   3. Fixes self-references (e.g. Config.PermissionAction → PermissionAction)
- *   4. If the file is index.ts, renames it to <lowercase-name>.ts
- *   5. Creates/updates index.ts with `export * as Foo from "./<file>"`
- *   6. Rewrites import paths across src/, test/, and script/
- *   7. Fixes sibling imports within the same directory
+ * Default mode:
+ *   1. Finds `export namespace Foo { ... }` (ast-grep)
+ *   2. Removes wrapper, dedents body, fixes self-references
+ *   3. Appends `export * as Foo from "./file"` to the file (self-reexport)
+ *   4. Rewrites consumer imports to point at the file directly
+ *
+ * Retrofit mode (--retrofit):
+ *   File already has flat exports (from previous barrel migration).
+ *   1. Reads the barrel index.ts to find the namespace name
+ *   2. Adds `export * as Foo from "./file"` to the source file
+ *   3. Rewrites consumers from barrel import to direct file import
+ *
+ * Does NOT create barrel index.ts files.
  *
  * Requires: ast-grep (`brew install ast-grep` or `cargo install ast-grep`)

-# Namespace → flat export migration
+# Namespace → self-reexport 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.
+Migrate `export namespace` to flat module exports with a self-referential
+`export * as` at the bottom of each file. No barrel files.
 
-## What changes and what doesn't
+## The pattern
 
-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"`:
+Each module file has flat exports plus one line at the bottom that re-exports
+itself as a namespace:
 
 ```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:
+// config/config.ts
+import { Log } from "../util/log"
 
-```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
+export interface Info { model: string }
+export function load(): Info { ... }
+export const JsonError = NamedError.create(...)
 
-The worst import chain in the codebase:
-
-```

+// Self-reexport: creates a named `Config` export that consumers can import
+export * as Config from "./config"
 ```
 
-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`)
+Consumers import the namespace by name — editors auto-import this like any
+named export:
 
 ```ts
-// index.ts
-export * as Effect from "./Effect.ts"
-export * as Schema from "./Schema.ts"
-export * as Stream from "./Stream.ts"
-// ~134 modules
+import { Config } from "../config/config"
+Config.load()
+Config.JsonError.isInstance(x)
 ```
 
-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.
+## Why this pattern
 
-### 3. `sideEffects: []` and deep imports
+We tested every option with Bun. Three things matter: tree-shaking, circular
+imports, and editor autocomplete.
 
-```jsonc
-// package.json
-{ "sideEffects": [] }
 ```
+A. Barrel (export * as Foo + Bar from index.ts)
+   Runtime:  foo LOADED even though only Bar used  ❌
+   Bundled:  foo LOADED if it has side effects     ❌
+   Autocomplete: works (named export from barrel)
 
-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
+B. import * as Bar from "./bar" (direct, no barrel)
+   Runtime:  only bar loaded                       ✅
+   Bundled:  only bar loaded                       ✅
+   Autocomplete: broken (editors can't auto-import) ❌
 
-```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
+C. Self-reexport: export * as Bar from "./bar" inside bar.ts
+   Runtime:  only bar loaded                       ✅
+   Bundled:  only bar loaded                       ✅
+   Autocomplete: works (named export from file)    ✅
 ```
 
-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):**

-
-### 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:
+The self-reexport gives us tree-shaking + autocomplete + no barrels.
 
-```
-# 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
-```
+### Bundle overhead
 
-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"
+The self-reexport adds ~240 bytes per module (an `Object.defineProperty`
+wrapper). At 100 modules that's ~24KB — irrelevant for a CLI binary.
 
-// AFTER — resolves to provider/index.ts, same Provider object
-import { Provider } from "../provider"
-```
+### The `Foo.Foo.Foo` thing
 
-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.
+`Config.Config.Config.load()` compiles and runs. It's a harmless side effect
+of self-referential modules. Nobody would write it.
 
-**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.
+## Why barrel files don't work
 
-**Order of conversion** (by risk / size, do small modules first):
+Barrel files (`index.ts` with `export * as`) have two problems:
 
-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`
+1. **Bun loads all re-exported modules** when you import through a barrel,
+   even if you only use one. This happens at both runtime and bundle time
+   for modules with side effects (which ours have — top-level imports).
 
-### Phase 2: Build configuration
+2. **Circular import risk.** Sibling files can't import through their own
+   barrel, and cross-directory barrel cycles cause runtime `ReferenceError`.
 
-After the module structure supports tree-shaking:
+## The migration
 
-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.
+There are two tasks:
 
-## Automation
+### Task 1: Convert remaining `export namespace` files (~50)
 
-The transformation is scripted. From `packages/opencode`:
+For each file:
 
-```bash
-bun script/unwrap-namespace.ts <file> [--dry-run]
-```
+1. Remove the `export namespace Foo {` wrapper and closing `}`
+2. Dedent the body
+3. Add `export * as Foo from "./file"` at the bottom
+4. Rewrite consumer imports: `import { Foo } from "..."` stays the same
+   if the path already points at the file. If it points at a barrel,
+   change it to point at the file directly.
 
-The script uses ast-grep for accurate AST-based namespace boundary detection
-(no false matches from braces in strings/templates/comments), then:
+### Task 2: Fix already-converted files (~32 barrel dirs)
 
-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
+These were converted in the earlier barrel-based migration. Each directory
+has an `index.ts` barrel and flat-exported source files. To migrate:
 
-### Walkthrough: converting a module
+1. Add `export * as Foo from "./file"` to the bottom of each source file
+2. Change consumers from `import { Foo } from "../dir"` (barrel) to
+   `import { Foo } from "../dir/file"` (direct)
+3. The barrel `index.ts` can be deleted or left in place (harmless once
+   nothing imports through it)
 
-Using `Provider` as an example:
+### Automation
 
 ```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'
+# Convert an unconverted namespace file:
+bun script/unwrap-namespace.ts src/session/session.ts --dry-run
+bun script/unwrap-namespace.ts src/session/session.ts
 
-# 4. Verify
-bun typecheck
-bun run test
+# Retrofit an already-converted file (add self-reexport + fix consumers):
+bun script/unwrap-namespace.ts src/config/config.ts --retrofit --dry-run
+bun script/unwrap-namespace.ts src/config/config.ts --retrofit
 ```
 
-**What changes on disk:**
+The script handles both cases:
 
-```
-# 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
-```
+- **Default mode**: unwraps namespace + adds self-reexport + rewrites imports
+- **Retrofit mode** (`--retrofit`): file already has flat exports, just adds
+  the self-reexport line and rewrites consumers from barrel to direct
 
-**What changes in consumer code:**
+### Verification
 
-```ts
-// BEFORE
-import { Provider } from "../provider/provider"
+After any conversion:
 
-// AFTER — shorter path, same Provider object
-import { Provider } from "../provider"
+```bash
+bunx --bun tsgo --noEmit                                # typecheck
+bun run --conditions=browser ./src/index.ts generate    # circular import check
 ```
 
-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

-## Circular import rules
-
-Barrel files (`index.ts` with `export * as`) introduce circular import risks.
-These cause `ReferenceError: Cannot access 'X' before initialization` at
-runtime — not caught by the type checker.
+- **No `export namespace`.** Use flat named exports.
+- **No barrel `index.ts` for internal code.**
+- **Every module file gets a self-reexport** at the bottom:
+  `export * as Foo from "./foo"`
+- **Consumers import the namespace by name:**
+  `import { Foo } from "../path/to/foo"`
 
-### Rule 1: Sibling files never import through their own barrel
+## Remaining work
 
-Files in the same directory must import directly from the source file, never
-through `"."` or `"@/<own-dir>"`:
+### Unconverted (~50 namespaces):
 
-```ts
-// BAD — circular: index.ts re-exports both files, so A → index → B → index → A
-import { Sibling } from "."
-
-// GOOD — direct, no cycle
-import * as Sibling from "./sibling"
-```
+**Session directory (14)** — deep cross-directory cycles currently via barrel:
 
-### Rule 2: Cross-directory imports must not form cycles through barrels
+- SessionRunState, SystemPrompt, Message, SessionRetry, SessionProcessor,
+  SessionRevert, Instruction, SessionSummary, Todo, LLM, SessionStatus,
+  SessionCompaction, SessionPrompt, MessageV2
 
-If `src/lsp/lsp.ts` imports `Config` from `"../config"`, and
-`src/config/config.ts` imports `LSPServer` from `"../lsp"`, that's a cycle:
+**Special cases:**
 
-```
-lsp/lsp.ts → config/index.ts → config/config.ts → lsp/index.ts → lsp/lsp.ts 💥
-```
+- `flag/flag.ts` — uses `Object.defineProperty(Flag, ...)`, needs restructuring
+- `account/repo.ts` — ast-grep fails, needs manual conversion
+- `v2/` (multi-namespace files) — SessionEvent (5 nested), etc.
 
-Fix by importing the specific file, breaking the cycle:
+**Other standalone modules** (~30 across server/, cli/, plugin/, etc.)
 
-```ts
-// In config/config.ts — import directly, not through the lsp barrel
-import * as LSPServer from "../lsp/server"
-```
-
-### Why the type checker doesn't catch this
-
-TypeScript resolves types lazily — it doesn't evaluate module-scope
-expressions. The `ReferenceError` only happens at runtime when a module-scope
-`const` or function call accesses a value from a circular dependency that
-hasn't finished initializing. The SDK build step (`bun run --conditions=browser
-./src/index.ts generate`) is the reliable way to catch these because it
-evaluates all modules eagerly.
-
-### How to verify
-
-After any namespace conversion, run:
-
-```bash
-cd packages/opencode
-bun run --conditions=browser ./src/index.ts generate
-```
+### Already converted (32 barrel dirs) — need retrofit:
 
-If this completes without `ReferenceError`, the module graph is safe.
