 ## Effect service adoption in already-migrated code
 
-Some services are effectified but still use raw `Filesystem.*` or `Process.spawn` instead of the Effect equivalents. These are low-hanging fruit — the layers already exist, they just need the dependency swap.
+Some already-effectified areas still use raw `Filesystem.*` or `Process.spawn` in their implementation or helper modules. These are low-hanging fruit — the layers already exist, they just need the dependency swap.
 
 ### `Filesystem.*` → `AppFileSystem.Service` (yield in layer)
 
-- [ ] `file/index.ts` — 11 calls (the File service itself)
-- [ ] `config/config.ts` — 7 calls
-- [ ] `auth/index.ts` — 3 calls
-- [ ] `skill/index.ts` — 3 calls
-- [ ] `file/time.ts` — 1 call
+- [ ] `file/index.ts` — 1 remaining `Filesystem.readText()` call in untracked diff handling
+- [ ] `config/config.ts` — 5 remaining `Filesystem.*` calls in `installDependencies()`
+- [ ] `provider/provider.ts` — 1 remaining `Filesystem.readJson()` call for recent model state
 
 ### `Process.spawn` → `ChildProcessSpawner` (yield in layer)
 
-- [ ] `format/index.ts` — 1 call
+- [ ] `format/formatter.ts` — 2 remaining `Process.spawn()` checks (`air`, `uv`)
+- [ ] `lsp/server.ts` — multiple `Process.spawn()` installs/download helpers
 
 ## Filesystem consolidation
 
-`util/filesystem.ts` (raw fs wrapper) is used by **64 files**. The effectified `AppFileSystem` service (`filesystem/index.ts`) exists but only has **8 consumers**. As services and tools are effectified, they should switch from `Filesystem.*` to yielding `AppFileSystem.Service` — this happens naturally during each migration, not as a separate effort.
+`util/filesystem.ts` (raw fs wrapper) is currently imported by **34 files**. The effectified `AppFileSystem` service (`filesystem/index.ts`) is currently imported by **15 files**. As services and tools are effectified, they should switch from `Filesystem.*` to yielding `AppFileSystem.Service` — this happens naturally during each migration, not as a separate effort.
 
-Similarly, **28 files** still import raw `fs` or `fs/promises` directly. These should migrate to `AppFileSystem` or `Filesystem.*` as they're touched.

 Current raw fs users that will convert during tool migration:
 
 - `tool/read.ts` — fs.createReadStream, readline
 - `tool/apply_patch.ts` — fs/promises
-- `tool/bash.ts` — fs/promises
 - `file/ripgrep.ts` — fs/promises
-- `storage/storage.ts` — fs/promises
 - `patch/index.ts` — fs, fs/promises
