refactor(tool): reuse edit entry schema in multiedit

Pre-migration safety net for the upcoming tool-by-tool zod\u2192Schema
conversion. Every tool's parameters schema now has:

1. A JSON Schema snapshot (`z.toJSONSchema` with `io: "input"`) \u2014 this
   captures exactly what the LLM sees at tool registration time, so any
   drift caused by a future migration fails the snapshot.
2. Parse-accept/parse-reject assertions per tool pinning the
   user-visible behavioural contract (required fields, refinement
   bounds, enum membership, default values).

To make the snapshots possible without standing up each tool's full
Effect runtime, every tool file now exports its parameters schema as
`Parameters` at module scope:

- 9 tools already had a module-level const \u2014 just added `export`, and
  standardised the name to `Parameters` (uppercase) where it was
  previously `parameters`.
- 9 tools had their schema inline inside `Tool.define` \u2014 hoisted to
  module scope under the same `Parameters` name and wired back through.

Zero behaviour change: Tool.define still sees the same schema, runtime
validation path is identical, SDK (types.gen.ts + openapi.json) is
byte-identical, and the full 2054-test suite passes.

18 JSON Schema snapshots and 43 explicit parse/reject assertions for the
18 built-in tools (apply_patch, bash, codesearch, edit, glob, grep,
invalid, lsp, multiedit, plan, question, read, skill, task, todo,
webfetch, websearch, write).

-- `server/instance/session.ts` still depends on `Session`, `SessionPrompt`, `SessionRevert`, `SessionCompaction`, `SessionSummary`, `ShareSession`, `Agent`, and `Permission` facades.
-- `src/effect/app-runtime.ts` still references many facade namespaces directly, so it should stay in view during each deletion.
+- `src/cli/cmd/tui/config/tui.ts` still exports `makeRuntime(...)` plus async facade helpers for `get()` and `waitForDependencies()`.
+- `src/npm/index.ts` still exports `makeRuntime(...)` plus async facade helpers for `install()`, `add()`, `outdated()`, and `which()`.

 5. For CLI readability, extract file-local preload helpers when the handler starts doing config load + service load + batched effect fanout inline.
 6. When rebasing a facade branch after nearby merges, prefer the already-cleaned service/test version over older inline facade-era code.
 
-## Next batch
+## Remaining work
 
-Recommended next five, in order:
+Most of the original facade-removal backlog is already done. The practical remaining work is narrower now:
 
-1. `src/permission/index.ts`
-2. `src/agent/agent.ts`
-3. `src/session/summary.ts`
-4. `src/session/revert.ts`
-5. `src/mcp/auth.ts`
-
-Why this batch:
-
-- It keeps pushing the session-adjacent cleanup without jumping straight into `session/index.ts` or `session/prompt.ts`.
-- `Permission`, `Agent`, `SessionSummary`, and `SessionRevert` all reduce fanout in `server/instance/session.ts`.
-- `McpAuth` is small and closely related to the just-landed `MCP` cleanup.
-
-After that batch, the expected follow-up is the main session cluster:
-
-1. `src/session/index.ts`
-2. `src/session/prompt.ts`
-3. `src/session/compaction.ts`
+1. remove the `Npm` runtime-backed facade from `src/npm/index.ts`
+2. remove the `TuiConfig` runtime-backed facade from `src/cli/cmd/tui/config/tui.ts`
+3. keep `src/project/instance.ts` in the separate instance-context migration, not this checklist

+
+### Schema.Class vs Schema.Struct
+
+The pattern choice determines whether a schema becomes a **named** export in the SDK or stays **anonymous inline**.
+
+**Schema.Class** emits a named `$ref` in OpenAPI via its identifier → produces a named `export type Foo = ...` in `types.gen.ts`:
+
+```ts
+export class Info extends Schema.Class<Info>("FooConfig")({ ... }) {
+  static readonly zod = zod(this)
+}
+```
+
+**Schema.Struct** stays anonymous and is inlined everywhere it is referenced:
+
+```ts
+export const Info = Schema.Struct({ ... }).pipe(
+  withStatics((s) => ({ zod: zod(s) })),
+)
+export type Info = Schema.Schema.Type<typeof Info>
+```
+
+When to use each:
+
+- Use **Schema.Class** when:
+  - the original Zod had `.meta({ ref: ... })` (preserve the existing named SDK type byte-for-byte)
+  - the schema is a top-level endpoint request or response (SDK consumers benefit from a stable importable name)
+- Use **Schema.Struct** when:
+  - the type is only used as a nested field inside another named schema
+  - the original Zod was anonymous and promoting it would bloat SDK types with no import value
+
+Promoting a previously-anonymous schema to Schema.Class is acceptable when it is top-level or endpoint-facing, but call it out in the PR — it is an additive SDK change (`export type Foo = ...` newly appears) even if it preserves the JSON shape.
+
+Schemas that are **not** pure objects (enums, unions, records, tuples) cannot use Schema.Class. For those, add `.annotate({ identifier: "FooName" })` to get the same named-ref behavior:

+This phase is no longer broadly open. There are 5 `makeRuntime(...)` call sites under `src/`, and only a small subset are still ordinary facade-removal targets. The live checklist now lives in `facades.md`.
 
 These facades exist because cyclic imports used to force each service to build its own independent runtime. Now that the layer DAG is acyclic and `AppRuntime` (`src/effect/app-runtime.ts`) composes everything into one `ManagedRuntime`, we're removing them.

 - `ShareNext` — migrated 2026-04-11. Swapped remaining async callers to `AppRuntime.runPromise(ShareNext.Service.use(...))`, removed the `makeRuntime(...)` facade, and kept instance bootstrap on the shared app runtime.
 - `SessionTodo` — migrated 2026-04-10. Already matched the target service shape in `session/todo.ts`: single namespace, traced Effect methods, and no `makeRuntime(...)` facade remained; checklist updated to reflect the completed migration.

-The main migration targets are:
+Files that are already mostly on the intended service-yielding shape:
 
-- [ ] `server/instance/session.ts` — heaviest; still has many direct facade calls for Session, SessionPrompt, SessionRevert, SessionCompaction, SessionShare, SessionSummary, Agent, Bus
-- [ ] `server/instance/global.ts` — still has direct facade calls for Config and instance lifecycle actions
-- [ ] `server/instance/provider.ts` — still has direct facade calls for Config and Provider
-- [ ] `server/instance/question.ts` — partially converted; still worth tracking here until it consistently uses the composed style
-- [ ] `server/instance/pty.ts` — still calls Pty facades directly
-- [ ] `server/instance/experimental.ts` — mixed state; some handlers are already composed, others still use facades
+- [x] `server/routes/instance/question.ts` — handlers yield `Question.Service`
+- [x] `server/routes/instance/provider.ts` — handlers yield `Provider.Service`, `ProviderAuth.Service`, and `Config.Service`
+- [x] `server/routes/instance/permission.ts` — handlers yield `Permission.Service`
+- [x] `server/routes/instance/mcp.ts` — handlers mostly yield `MCP.Service`
+- [x] `server/routes/instance/pty.ts` — handlers yield `Pty.Service`
 
-Additional route files that still participate in the migration:
+Files still worth tracking here:
 
-- [ ] `server/instance/index.ts` — Vcs, Agent, Skill, LSP, Format
-- [ ] `server/instance/file.ts` — Ripgrep, File, LSP
-- [ ] `server/instance/mcp.ts` — MCP facade-heavy
-- [ ] `server/instance/permission.ts` — Permission
-- [ ] `server/instance/workspace.ts` — Workspace
-- [ ] `server/instance/tui.ts` — Bus and Session
-- [ ] `server/instance/middleware.ts` — Session and Workspace lookups
+- [ ] `server/routes/instance/session.ts` — still the heaviest mixed file; many handlers are composed, but the file still mixes patterns and has direct `Bus.publish(...)` / `Session.list(...)` usage
+- [ ] `server/routes/instance/index.ts` — mostly converted, but still has direct `Instance.dispose()` / `Instance.*` reads for `/instance/dispose` and `/path`
+- [ ] `server/routes/instance/file.ts` — most handlers yield services, but `/find` still passes `Instance.directory` directly into ripgrep and `/find/symbol` is still stubbed
+- [ ] `server/routes/instance/experimental.ts` — mixed state; many handlers are composed, but some still rely on `runRequest(...)` or direct `Instance.project` reads
+- [ ] `server/routes/instance/middleware.ts` — still enters the instance via `Instance.provide(...)`
+- [ ] `server/routes/global.ts` — still uses `Instance.disposeAll()` and remains partly outside the fully-composed style
 
 ## Notes
 
-- Some handlers already use `AppRuntime.runPromise(Effect.gen(...))` in isolated places. Keep pushing those files toward one consistent style.
-- Route conversion is closely tied to facade removal. As services lose `makeRuntime`-backed async exports, route handlers should switch to yielding the service directly.
+- Route conversion is now less about facade removal and more about removing the remaining direct `Instance.*` reads, `Instance.provide(...)` boundaries, and small Promise-style bridges inside route files.
+- `jsonRequest(...)` / `runRequest(...)` already provide a good intermediate shape for many handlers. The remaining cleanup is mostly consistency work in the heavier files.
