serve.ts: keep push relay additions (imports, types, helpers)
status.ts: use consolidated @/effect import path from dev, keep Log import

 - 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.

 Do not re-architect business logic during the HTTP migration. `HttpApi` handlers should call the same Effect services already used by the Hono handlers.
 
-### 4. Build in parallel, do not bridge into Hono
+### 4. Bridge into Hono behind a feature flag
 
-The `HttpApi` implementation lives under `src/server/instance/httpapi/` as a standalone Effect HTTP server. It is **not mounted into the Hono app**. There is no `toWebHandler` bridge, no Hono `Handler` export, and no `.route()` call wiring it into `experimental.ts`.
+The `HttpApi` routes are bridged into the Hono server via `HttpRouter.toWebHandler` with a shared `memoMap`. This means:
 
-The standalone server (`httpapi/server.ts`) can be started independently and proves the routes work. Tests exercise it via `HttpRouter.serve` with `NodeHttpServer.layerTest`.
+- one process, one port — no separate server
+- the Effect handler shares layer instances with `AppRuntime` (same `Question.Service`, etc.)
+- Effect middleware handles auth and instance lookup independently from Hono middleware
+- Hono's `.all()` catch-all intercepts matching paths before the Hono route handlers
 
-The goal is to build enough route coverage in the Effect server that the Hono server can eventually be replaced entirely. Until then, the two implementations exist side by side but are completely separate processes.
+The bridge is gated behind `OPENCODE_EXPERIMENTAL_HTTPAPI` (or `OPENCODE_EXPERIMENTAL`). When the flag is off (default), all requests go through the original Hono handlers unchanged.
 
-### 5. Migrate JSON route groups gradually
+```ts
+// in instance/index.ts
+if (Flag.OPENCODE_EXPERIMENTAL_HTTPAPI) {
+  const handler = ExperimentalHttpApiServer.webHandler().handler
+  app.all("/question", (c) => handler(c.req.raw)).all("/question/*", (c) => handler(c.req.raw))
+}
+```
 
-If the parallel slice works well, migrate additional JSON route groups one at a time. Leave streaming-style endpoints on Hono until there is a clear reason to move them.
+The Hono route handlers are always registered (after the bridge) so `hono-openapi` generates the OpenAPI spec entries that feed SDK codegen. When the flag is on, these handlers are dead code — the `.all()` bridge matches first.
+
+### 5. Observability
+
+The `webHandler` provides `Observability.layer` via `Layer.provideMerge`. Since the `memoMap` is shared with `AppRuntime`, the tracing provider is deduplicated — no extra initialization cost.
+
+This gives:
+
+- **spans**: `Effect.fn("QuestionHttpApi.list")` etc. appear in traces alongside service-layer spans
+- **HTTP logs**: `HttpMiddleware.logger` emits structured `Effect.log` entries with `http.method`, `http.url`, `http.status` annotations, flowing to motel via `OtlpLogger`
+
+### 6. Migrate JSON route groups gradually
+
+As each route group is ported to `HttpApi`:
+
+1. change its `root` path from `/experimental/httpapi/<group>` to `/<group>`
+2. add `.all("/<group>", handler)` / `.all("/<group>/*", handler)` to the flag block in `instance/index.ts`
+3. for partial ports (e.g. only `GET /provider/auth`), bridge only the specific path
+4. verify SDK output is unchanged
+
+Leave streaming-style endpoints on Hono until there is a clear reason to move them.

+# 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)
+   ```
+

+
+### 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.
+
+## 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.
