 - 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
- In `src/config`, follow the existing self-export pattern at the top of the file (for example `export * as ConfigAgent from "./agent"`) when adding a new config module.

 Reduce total variable count by inlining when a value is only used once.

-/**
- * Automate the full per-file namespace→self-reexport migration:
- *
- *   1. Create a worktree at ../opencode-worktrees/ns-<slug> on a new branch
- *      `kit/ns-<slug>` off `origin/dev`.
- *   2. Symlink `node_modules` from the main repo into the worktree root so
- *      builds work without a fresh `bun install`.
- *   3. Run `script/unwrap-and-self-reexport.ts` on the target file inside the worktree.
- *   4. Verify:
- *        - `bunx --bun tsgo --noEmit` (pre-existing plugin.ts cross-worktree
- *          noise ignored — we compare against a pre-change baseline captured
- *          via `git stash`, so only NEW errors fail).
- *        - `bun run --conditions=browser ./src/index.ts generate`.
- *        - Relevant tests under `test/<dir>` if that directory exists.
- *   5. Commit, push with `--no-verify`, and open a PR titled after the
- *      namespace.
- *
- * Usage:
- *
- *   bun script/batch-unwrap-pr.ts src/file/ignore.ts
- *   bun script/batch-unwrap-pr.ts src/file/ignore.ts src/file/watcher.ts   # multiple
- *   bun script/batch-unwrap-pr.ts --dry-run src/file/ignore.ts             # plan only
- *
- * Repo assumptions:
- *
- *   - Main checkout at /Users/kit/code/open-source/opencode (configurable via
- *     --repo-root=...).
- *   - Worktree root at /Users/kit/code/open-source/opencode-worktrees
- *     (configurable via --worktree-root=...).
- *
- * The script does NOT enable auto-merge; that's a separate manual step if we
- * want it.

- * Collapse a single-namespace barrel directory into a dir/index.ts module.
- *
- * Given a directory `src/foo/` that contains:
- *
- *   - `index.ts`  (exactly `export * as Foo from "./foo"`)
- *   - `foo.ts`    (the real implementation)
- *   - zero or more sibling files
- *
- * this script:
- *
- *   1. Deletes the old `index.ts` barrel.
- *   2. `git mv`s `foo.ts` → `index.ts` so the implementation IS the directory entry.
- *   3. Appends `export * as Foo from "."` to the new `index.ts`.
- *   4. Rewrites any same-directory sibling `*.ts` files that imported
- *      `./foo` (with or without the namespace name) to import `"."` instead.
- *
- * Consumer files outside the directory keep importing from the directory
- * (`"@/foo"` / `"../foo"` / etc.) and continue to work, because
- * `dir/index.ts` now provides the `Foo` named export directly.
- *
- * Usage:
- *
- *   bun script/collapse-barrel.ts src/bus
- *   bun script/collapse-barrel.ts src/bus --dry-run
- *
- * Notes:
- *
- *   - Only works on directories whose barrel is a single
- *     `export * as Name from "./file"` line. Refuses otherwise.
- *   - Refuses if the implementation file name already conflicts with
- *     `index.ts`.
- *   - Safe to run repeatedly: a second run on an already-collapsed dir
- *     will exit with a clear message.

-# Namespace → self-reexport migration
+# Namespace → flat export migration

-Migrate every `export namespace Foo { ... }` to flat top-level exports plus a
-single self-reexport line at the bottom of the same file:
+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
-export * as Foo from "./foo"
+// BEFORE — points at the file directly
+import { Provider } from "../provider/provider"
+
+// AFTER — resolves to provider/index.ts, same Provider namespace
+import { Provider } from "../provider"

-No barrel `index.ts` files. No cross-directory indirection. Consumers keep the
-exact same `import { Foo } from "../foo/foo"` ergonomics.
+## Why this matters right now

-## Why this pattern
+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.

-We tested three options against Bun, esbuild, Rollup (what Vite uses under the
-hood), Bun's runtime, and Node's native TypeScript runner.

+`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 = {}))
 ```

- **`export namespace`** compiles to an IIFE. Bundlers see one opaque function
-  call and can't analyze what's used. Node's native TS runner rejects the
-  syntax outright: `SyntaxError: TypeScript namespace declaration is not
-supported in strip-only mode`.
- **Barrel `index.ts`** files (`export * as Foo from "./foo"` in a separate
-  file) force every re-exported sibling to evaluate when you import one name.
-  Siblings with side effects (top-level imports of SDKs, etc.) always load.
- **Self-reexport** keeps the file as plain ESM. Bundlers see static named
-  exports. The module is only pulled in when something actually imports from
-  it. There is no barrel hop, so no sibling contamination and no circular
-  import hazard.
+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)`.

-Bundle overhead for the self-reexport wrapper is roughly 240 bytes per module
-(`Object.defineProperty` namespace proxy). At ~100 modules that's ~24KB —
-negligible for a CLI binary.
+### What `export * as` does differently

-## The pattern
+`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.

-### Before
+### Concrete impact

-```ts
-// src/permission/arity.ts
-export namespace BashArity {
-  export function prefix(tokens: string[]) { ... }
-}
-```
-
-### After
-
-```ts
-// src/permission/arity.ts
-export function prefix(tokens: string[]) { ... }
-
-export * as BashArity from "./arity"
-```
-
-Consumers don't change at all:
-
-```ts
-import { BashArity } from "@/permission/arity"
-BashArity.prefix(...) // still works
-```
-
-Editors still auto-import `BashArity` like any named export, because the file
-does have a named `BashArity` export at the module top level.
-
-### Odd but harmless
-
-`BashArity.BashArity.BashArity.prefix(...)` compiles and runs because the
-namespace contains a re-export of itself. Nobody would write that. Not a
-problem.
-
-## Why this is different from what we tried first
-
-An earlier pass used sibling barrel files (`index.ts` with `export * as ...`).
-That turned out to be wrong for our constraints:
-
-1. The barrel file always loads all its sibling modules when you import
-   through it, even if you only need one. For our CLI this is exactly the
-   cost we're trying to avoid.
-2. Barrel + sibling imports made it very easy to accidentally create circular
-   imports that only surface as `ReferenceError` at runtime, not at
-   typecheck.
-
-The self-reexport has none of those issues. There is no indirection. The
-file and the namespace are the same unit.
-
-## Why this matters for startup
-
-The worst import chain in the codebase looks like:

-All of that currently gets pulled in just to do `.isInstance()` on a handful
-of error classes. The namespace IIFE shape is the main reason bundlers cannot
-strip the unused parts. Self-reexport + flat ESM fixes it.
+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

-From `packages/opencode`:
+The transformation is scripted. From `packages/opencode`:

 ```bash
 bun script/unwrap-namespace.ts <file> [--dry-run]
 ```

-The script:
+The script uses ast-grep for accurate AST-based namespace boundary detection
+(no false matches from braces in strings/templates/comments), then:

-1. Uses ast-grep to locate the `export namespace Foo { ... }` block accurately.
-2. Removes the `export namespace Foo {` line and the matching closing `}`.
-3. Dedents the body by one indent level (2 spaces).
-4. Rewrites `Foo.Bar` self-references inside the file to just `Bar`.
-5. Appends `export * as Foo from "./<basename>"` at the bottom of the file.
-6. Never creates a barrel `index.ts`.
+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

-### Typical flow for one file
+### Walkthrough: converting a module
+
+Using `Provider` as an example:

 ```bash
-# 1. Preview
-bun script/unwrap-namespace.ts src/permission/arity.ts --dry-run
+# 1. Preview what will change
+bun script/unwrap-namespace.ts src/provider/provider.ts --dry-run

-# 2. Apply
-bun script/unwrap-namespace.ts src/permission/arity.ts
+# 2. Apply the transformation
+bun script/unwrap-namespace.ts src/provider/provider.ts

-# 3. Verify
-cd packages/opencode
-bunx --bun tsgo --noEmit
-bun run --conditions=browser ./src/index.ts generate
-bun run test <affected test files>
+# 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
 ```

-### Consumer imports usually don't need to change
+**What changes on disk:**

-Most consumers already import straight from the file, e.g.:
+```
+# 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
-import { BashArity } from "@/permission/arity"
-import { Config } from "@/config/config"
+// BEFORE
+import { Provider } from "../provider/provider"
+
+// AFTER — shorter path, same Provider object
+import { Provider } from "../provider"
 ```

-Because the file itself now does `export * as Foo from "./foo"`, those imports
-keep working with zero edits.
+All property access (`Provider.Service`, `Provider.ModelNotFoundError`, etc.)
+stays identical.

-The only edits needed are when a consumer was importing through a previous
-barrel (`"@/config"` or `"../config"` resolving to `config/index.ts`). In
-that case, repoint it at the file:
+### Two cases the script handles

-```ts
-// before
-import { Config } from "@/config"
+**Case A: file is NOT `index.ts`** (e.g. `provider/provider.ts`)

-// after
-import { Config } from "@/config/config"
-```
+- Rewrites the file in place (unwrap + dedent)
+- Creates `provider/index.ts` as the barrel
+- Import paths change: `"../provider/provider"` → `"../provider"`

-### Dynamic imports in tests
+**Case B: file IS `index.ts`** (e.g. `bus/index.ts`)

-If a test did `const { Foo } = await import("../../src/x/y")`, the destructure
-still works because of the self-reexport. No change required.
+- 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`

-## Verification checklist (per PR)
+## Do I need to split errors/schemas into subfiles?

-Run all of these locally before pushing:
+**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.

-```bash
-cd packages/opencode
-bunx --bun tsgo --noEmit
-bun run --conditions=browser ./src/index.ts generate
-bun run test <affected test files>
-```
+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.

-Also do a quick grep in `src/`, `test/`, and `script/` to make sure no
-consumer is still importing the namespace from an old barrel path that no
-longer exports it.
-
-The SDK build step (`bun run --conditions=browser ./src/index.ts generate`)
-evaluates every module eagerly and is the most reliable way to catch circular
-import regressions at runtime — the typechecker does not catch these.
-
-## Rules for new code
-
- No new `export namespace`.
- Every module directory has a single canonical file — typically
-  `dir/index.ts` — with flat top-level exports and a self-reexport at the
-  bottom:
-  `export * as Foo from "."`
- Consumers import from the directory:
-  `import { Foo } from "@/dir"` or `import { Foo } from "../dir"`.
- No sibling barrel files. If a directory has multiple independent
-  namespaces, they each get their own file (e.g. `config/config.ts`,
-  `config/plugin.ts`) and their own self-reexport; the `index.ts` in that
-  directory stays minimal or does not exist.
- If a file needs a sibling, import the sibling file directly:
-  `import * as Sibling from "./sibling"`, not `from "."`.
-
-### Why `dir/index.ts` + `"."` is fine for us
-
-A single-file module (e.g. `pty/`) can live entirely in `dir/index.ts`
-with `export * as Foo from "."` at the bottom. Consumers write the
-short form:
-
-```ts
-import { Pty } from "@/pty"
-```
-
-This works in Bun runtime, Bun build, esbuild, and Rollup. It does NOT
-work under Node's `--experimental-strip-types` runner:
-
-```
-node --experimental-strip-types entry.ts
-  ERR_UNSUPPORTED_DIR_IMPORT: Directory import '/.../pty' is not supported
-```
-
-Node requires an explicit file or a `package.json#exports` map for ESM.
-We don't care about that target right now because the opencode CLI is
-built with Bun and the web apps are built with Vite/Rollup. If we ever
-want to run raw `.ts` through Node, we'll need to either use explicit
-`.ts` extensions everywhere or add per-directory `package.json` exports
-maps.
-
-### When NOT to collapse to `index.ts`
-
-Some directories contain multiple independent namespaces where
-`dir/index.ts` would be misleading. Examples:
-
- `config/` has `Config`, `ConfigPaths`, `ConfigMarkdown`, `ConfigPlugin`,
-  `ConfigKeybinds`. Each lives in its own file with its own self-reexport
-  (`config/config.ts`, `config/plugin.ts`, etc.). Consumers import the
-  specific one: `import { ConfigPlugin } from "@/config/plugin"`.
- Same shape for `session/`, `server/`, etc.
-
-Collapsing one of those into `index.ts` would mean picking a single
-"canonical" namespace for the directory, which breaks the symmetry and
-hides the other files.
+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

-There are still dozens of `export namespace` files left across the codebase.
-Each one is its own small PR. Do them one at a time, verified locally, rather
-than batching by directory.
+| 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.
+
+## 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.
+
+### Rule 1: Sibling files never import through their own barrel
+
+Files in the same directory must import directly from the source file, never
+through `"."` or `"@/<own-dir>"`:
+
+```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"
+```
+
+### Rule 2: Cross-directory imports must not form cycles through barrels
+
+If `src/lsp/lsp.ts` imports `Config` from `"../config"`, and
+`src/config/config.ts` imports `LSPServer` from `"../lsp"`, that's a cycle:
+
+```
+lsp/lsp.ts → config/index.ts → config/config.ts → lsp/index.ts → lsp/lsp.ts 💥
+```
+
+Fix by importing the specific file, breaking the cycle:
+
+```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
+```
+
+If this completes without `ReferenceError`, the module graph is safe.
