            Requirements:
            1. Update all relevant locale docs under packages/web/src/content/docs/<locale>/ so they reflect these English page changes.
-            2. You MUST use the Task tool for translation work and launch subagents with subagent_type `translator` (defined in .opencode/agent/translator.md).
-            3. Do not translate directly in the primary agent. Use translator subagent output as the source for locale text updates.
-            4. Run translator subagent Task calls in parallel whenever file/locale translation work is independent.
-            5. Preserve frontmatter keys, internal links, code blocks, and existing locale-specific metadata unless the English change requires an update.
-            6. Keep locale docs structure aligned with their corresponding English pages.
-            7. Do not modify English source docs in packages/web/src/content/docs/*.mdx.
-            8. If no locale updates are needed, make no changes.

 - Decode tool stderr with `Bun.readableStreamToText`.
 - For large writes, use `Bun.write(Bun.file(path), text)`.

-NOTE: Bun.file(...).exists() will return `false` if the value is a directory.
-Use Filesystem.exists(...) instead if path can be file or directory
-
 ## Quick checklist

 - Use Bun APIs first.

-Read a file or directory from the local filesystem. If the path does not exist, an error is returned.
+Reads a file from the local filesystem. You can access any file directly by using this tool.
+Assume this tool is able to read all files on the machine. If the User provides a path to a file assume that path is valid. It is okay to read a file that does not exist; an error will be returned.

 Usage:
- The filePath parameter should be an absolute path.
- By default, this tool returns up to 2000 lines from the start of the file.
- The offset parameter is the line number to start from (1-indexed).
- To read later sections, call this tool again with a larger offset.
- Use the grep tool to find specific content in large files or files with long lines.
- If you are unsure of the correct file path, use the glob tool to look up filenames by glob pattern.
- Contents are returned with each line prefixed by its line number as `<line>: <content>`. For example, if a file has contents "foo\n", you will receive "1: foo\n". For directories, entries are returned one per line (without line numbers) with a trailing `/` for subdirectories.
- Any line longer than 2000 characters is truncated.
- Call this tool in parallel when you know there are multiple files you want to read.
- Avoid tiny repeated slices (30 line chunks). If you need more context, read a larger window.
- This tool can read image files and PDFs and return them as file attachments.
+- The filePath parameter must be an absolute path, not a relative path
+- By default, it reads up to 2000 lines starting from the beginning of the file
+- You can optionally specify a line offset and limit (especially handy for long files), but it's recommended to read the whole file by not providing these parameters
+- Any lines longer than 2000 characters will be truncated
+- Results are returned using cat -n format, with line numbers starting at 1
+- You have the capability to call multiple tools in a single response. It is always better to speculatively read multiple files as a batch that are potentially useful.
+- If you read a file that exists but has empty contents you will receive a system reminder warning in place of file contents.
+- You can read image files using this tool.

-## Payload limits
-
-Prevent blocking storage writes and runaway persisted size
-
---
-
-### Summary
-
-Large payloads (base64 images, terminal buffers) are currently persisted inside key-value stores:
-
- web: `localStorage` (sync, blocks the main thread)
- desktop: Tauri Store-backed async storage files (still expensive when values are huge)
-
-We’ll introduce size-aware persistence policies plus a dedicated “blob store” for large/binary data (IndexedDB on web; separate files on desktop). Prompt/history state will persist only lightweight references to blobs and load them on demand.
-
---
-
-### Goals
-
- Stop persisting image `dataUrl` blobs inside web `localStorage`
- Stop persisting image `dataUrl` blobs inside desktop store `.dat` files
- Store image payloads out-of-band (blob store) and load lazily when needed (e.g. when restoring a history item)
- Prevent terminal buffer persistence from exceeding safe size limits
- Keep persistence behavior predictable across web (sync) and desktop (async)
- Provide escape hatches via flags and per-key size caps
-
---
-
-### Non-goals
-
- Cross-device sync of images or terminal buffers
- Lossless persistence of full terminal scrollback on web
- Perfect blob deduplication or a complex reference-counting system on day one
-
---
-
-### Current state
-
- `packages/app/src/utils/persist.ts` uses `localStorage` (sync) on web and async storage only on desktop.
- Desktop storage is implemented via `@tauri-apps/plugin-store` and writes to named `.dat` files (see `packages/desktop/src/index.tsx`). Large values bloat these files and increase flush costs.
- Prompt history persists under `Persist.global("prompt-history")` (`packages/app/src/components/prompt-input.tsx`) and can include image parts (`dataUrl`).
- Prompt draft persistence uses `packages/app/src/context/prompt.tsx` and can also include image parts (`dataUrl`).
- Terminal buffer is serialized in `packages/app/src/components/terminal.tsx` and persisted in `packages/app/src/context/terminal.tsx`.
-
---
-
-### Proposed approach
-
-#### 1) Add per-key persistence policies (KV store guardrails)
-
-In `packages/app/src/utils/persist.ts`, add policy hooks for each persisted key:
-
- `warnBytes` (soft warning threshold)
- `maxBytes` (hard cap)
- `transformIn` / `transformOut` for lossy persistence (e.g. strip or refactor fields)
- `onOversize` strategy: `drop`, `truncate`, or `migrateToBlobRef`
-
-This protects both:
-
- web (`localStorage` is sync)
- desktop (async, but still expensive to store/flush giant values)
-
-#### 2) Add a dedicated blob store for large data
-
-Introduce a small blob-store abstraction used by the app layer:
-
- web backend: IndexedDB (store `Blob` values keyed by `id`)
- desktop backend: filesystem directory under the app data directory (store one file per blob)
-
-Store _references_ to blobs inside the persisted JSON instead of the blob contents.
-
-#### 3) Persist image parts as references (not base64 payloads)
-
-Update the prompt image model so the in-memory shape can still use a `dataUrl` for UI, but the persisted representation is reference-based.
-
-Suggested approach:
-
- Keep `ImageAttachmentPart` with:
-  - required: `id`, `filename`, `mime`
-  - optional/ephemeral: `dataUrl?: string`
-  - new: `blobID?: string` (or `ref: string`)
-
-Persistence rules:
-
- When writing persisted prompt/history state:
-  - ensure each image part is stored in blob store (`blobID`)
-  - persist only metadata + `blobID` (no `dataUrl`)
- When reading persisted prompt/history state:
-  - do not eagerly load blob payloads
-  - hydrate `dataUrl` only when needed:
-    - when applying a history entry into the editor
-    - before submission (ensure all image parts have usable `dataUrl`)
-    - when rendering an attachment preview, if required
-
---
-
-### Phased implementation steps
-
-1. Add guardrails in `persist.ts`
-
- Implement size estimation in `packages/app/src/utils/persist.ts` using `TextEncoder` byte length on JSON strings.
- Add a policy registry keyed by persist name (e.g. `"prompt-history"`, `"prompt"`, `"terminal"`).
- Add a feature flag (e.g. `persist.payloadLimits`) to enable enforcement gradually.
-
-2. Add blob-store abstraction + platform hooks
-
- Add a new app-level module (e.g. `packages/app/src/utils/blob.ts`) defining:
-  - `put(id, bytes|Blob)`
-  - `get(id)`
-  - `remove(id)`
- Extend the `Platform` interface (`packages/app/src/context/platform.tsx`) with optional blob methods, or provide a default web implementation and override on desktop:
-  - web: implement via IndexedDB
-  - desktop: implement via filesystem files (requires adding a Tauri fs plugin or `invoke` wrappers)
-
-3. Update prompt history + prompt draft persistence to use blob refs
-
- Update prompt/history serialization paths to ensure image parts are stored as blob refs:
-  - Prompt history: `packages/app/src/components/prompt-input.tsx`
-  - Prompt draft: `packages/app/src/context/prompt.tsx`
- Ensure “apply history prompt” hydrates image blobs only when applying the prompt (not during background load).
-
-4. One-time migration for existing persisted base64 images
-
- On read, detect legacy persisted image parts that include `dataUrl`.
- If a `dataUrl` is found:
-  - write it into the blob store (convert dataUrl → bytes)
-  - replace persisted payload with `{ blobID, filename, mime, id }` only
-  - re-save the reduced version
- If migration fails (missing permissions, quota, etc.), fall back to:
-  - keep the prompt entry but drop the image payload and mark as unavailable
-
-5. Fix terminal persistence (bounded snapshot)
-
- In `packages/app/src/context/terminal.tsx`, persist only:
-  - last `maxLines` and/or
-  - last `maxBytes` of combined text
- In `packages/app/src/components/terminal.tsx`, keep the full in-memory buffer unchanged.
-
-6. Add basic blob lifecycle cleanup
-   To avoid “blob directory grows forever”, add one of:
-
- TTL-based cleanup: store `lastAccessed` per blob and delete blobs older than N days
- Reference scan cleanup: periodically scan prompt-history + prompt drafts, build a set of referenced `blobID`s, and delete unreferenced blobs
-
-Start with TTL-based cleanup (simpler, fewer cross-store dependencies), then consider scan-based cleanup if needed.
-
---
-
-### Data migration / backward compatibility
-
- KV store data:
-  - policies should be tolerant of missing fields (e.g. `dataUrl` missing)
- Image parts:
-  - treat missing `dataUrl` as “not hydrated yet”
-  - treat missing `blobID` (legacy) as “not persisted” or “needs migration”
- Desktop:
-  - blob files should be namespaced (e.g. `opencode/blobs/<blobID>`) to avoid collisions
-
---
-
-### Risk + mitigations
-
- Risk: blob store is unavailable (IndexedDB disabled, desktop fs permissions).
-  - Mitigation: keep base state functional; persist prompts without image payloads and show a clear placeholder.
- Risk: lazy hydration introduces edge cases when submitting.
-  - Mitigation: add a pre-submit “ensure images hydrated” step; if hydration fails, block submission with a clear error or submit without images.
- Risk: dataUrl→bytes conversion cost during migration.
-  - Mitigation: migrate incrementally (only when reading an entry) and/or use `requestIdleCallback` on web.
- Risk: blob cleanup deletes blobs still needed.
-  - Mitigation: TTL default should be conservative; scan-based cleanup should only delete blobs unreferenced by current persisted state.
-
---
-
-### Validation plan
-
- Unit-level:
-  - size estimation + policy enforcement in `persist.ts`
-  - blob store put/get/remove round trips (web + desktop backends)
- Manual scenarios:
-  - attach multiple images, reload, and confirm:
-    - KV store files do not balloon
-    - images can be restored when selecting history items
-  - open terminal with large output and confirm reload restores bounded snapshot quickly
-  - confirm prompt draft persistence still works in `packages/app/src/context/prompt.tsx`
-
---
-
-### Rollout plan
-
- Phase 1: ship with `persist.payloadLimits` off; log oversize detections in dev.
- Phase 2: enable image blob refs behind `persist.imageBlobs` (web + desktop).
- Phase 3: enable terminal truncation and enforce hard caps for known hot keys.
- Phase 4: enable blob cleanup behind `persist.blobGc` (TTL first).
- Provide quick kill switches by disabling each flag independently.
-
---
-
-### Open questions
-
- What should the canonical persisted image schema be (`blobID` field name, placeholder shape, etc.)?
- Desktop implementation detail:
-  - add `@tauri-apps/plugin-fs` vs custom `invoke()` commands for blob read/write?
-  - where should blob files live (appDataDir) and what retention policy is acceptable?
- Web implementation detail:
-  - do we store `Blob` directly in IndexedDB, or store base64 strings?
- Should prompt-history images be retained indefinitely, or only for the last `MAX_HISTORY` entries?

-## Cache eviction
-
-Add explicit bounds for long-lived in-memory state
-
---
-
-### Summary
-
-Several in-memory caches grow without limits during long sessions. We’ll introduce explicit eviction (LRU + TTL + size caps) for sessions/messages/file contents and global per-directory sync stores.
-
---
-
-### Goals
-
- Prevent unbounded memory growth from caches that survive navigation
- Add consistent eviction primitives shared across contexts
- Keep UI responsive under heavy usage (many sessions, large files)
-
---
-
-### Non-goals
-
- Perfect cache hit rates or prefetch strategies
- Changing server APIs or adding background jobs
- Persisting caches for offline use
-
---
-
-### Current state
-
- Global sync uses per-directory child stores without eviction in `packages/app/src/context/global-sync.tsx`.
- File contents cached in `packages/app/src/context/file.tsx` with no cap.
- Session-heavy pages include `packages/app/src/pages/session.tsx` and `packages/app/src/pages/layout.tsx`.
-
---
-
-### Proposed approach
-
- Introduce a shared cache utility that supports:
-  - `maxEntries`, `maxBytes` (approx), and `ttlMs`
-  - LRU ordering with explicit `touch(key)` on access
-  - deterministic `evict()` and `clear()` APIs
- Apply the utility to:
-  - global-sync per-directory child stores (cap number of directories kept “hot”)
-  - file contents cache (cap by entries + bytes, with TTL)
-  - session/message caches (cap by session count, and optionally message count)
- Add feature flags per cache domain to allow partial rollout (e.g. `cache.eviction.files`).
-
---
-
-### Phased implementation steps
-
-1. Add a generic cache helper
-
- Create `packages/app/src/utils/cache.ts` with a small, dependency-free LRU+TTL.
- Keep it framework-agnostic and usable from Solid contexts.
-
-Sketch:
-
-```ts
-type CacheOpts = {
-  maxEntries: number
-  ttlMs?: number
-  maxBytes?: number
-  sizeOf?: (value: unknown) => number
-}
-
-function createLruCache<T>(opts: CacheOpts) {
-  // get, set, delete, clear, evictExpired, stats
-}
-```
-
-2. Apply eviction to file contents
-
- In `packages/app/src/context/file.tsx`:
-  - wrap the existing file-content map in the LRU helper
-  - approximate size via `TextEncoder` length of content strings
-  - evict on `set` and periodically via `requestIdleCallback` when available
- Add a small TTL (e.g. 10–30 minutes) to discard stale contents.
-
-3. Apply eviction to global-sync child stores
-
- In `packages/app/src/context/global-sync.tsx`:
-  - track child stores by directory key in an LRU with `maxEntries`
-  - call a `dispose()` hook on eviction to release subscriptions and listeners
- Ensure “currently active directory” is always `touch()`’d to avoid surprise evictions.
-
-4. Apply eviction to session/message caches
-
- Identify the session/message caching touchpoints used by `packages/app/src/pages/session.tsx`.
- Add caps that reflect UI needs (e.g. last 10–20 sessions kept, last N messages per session if cached).
-
-5. Add developer tooling
-
- Add a debug-only stats readout (console or dev panel) for cache sizes and eviction counts.
- Add a one-click “clear caches” action for troubleshooting.
-
---
-
-### Data migration / backward compatibility
-
- No persisted schema changes are required since this targets in-memory caches.
- If any cache is currently mirrored into persistence, keep keys stable and only change in-memory retention.
-
---
-
-### Risk + mitigations
-
- Risk: evicting content still needed causes extra refetches and flicker.
-  - Mitigation: always pin “active” entities and evict least-recently-used first.
- Risk: disposing global-sync child stores could leak listeners if not cleaned up correctly.
-  - Mitigation: require an explicit `dispose()` contract and add dev assertions for listener counts.
- Risk: approximate byte sizing is imprecise.
-  - Mitigation: combine entry caps with byte caps and keep thresholds conservative.
-
---
-
-### Validation plan
-
- Add tests for `createLruCache` covering TTL expiry, LRU ordering, and eviction triggers.
- Manual scenarios:
-  - open many files and confirm memory stabilizes and UI remains responsive
-  - switch across many directories and confirm global-sync does not continuously grow
-  - long session navigation loop and confirm caches plateau
-
---
-
-### Rollout plan
-
- Land cache utility first with flags default off.
- Enable file cache eviction first (lowest behavioral risk).
- Enable global-sync eviction next with conservative caps and strong logging in dev.
- Enable session/message eviction last after observing real usage patterns.
-
---
-
-### Open questions
-
- What are the current session/message cache structures and their ownership boundaries?
- Which child stores in `global-sync.tsx` have resources that must be disposed explicitly?
- What caps are acceptable for typical workflows (files open, directories visited, sessions viewed)?

-## Request throttling
-
-Debounce and cancel high-frequency server calls
-
---
-
-### Summary
-
-Some user interactions trigger bursts of server requests that can overlap and return out of order. We’ll debounce frequent triggers and cancel in-flight requests (or ignore stale results) for file search and LSP refresh.
-
---
-
-### Goals
-
- Reduce redundant calls from file search and LSP refresh
- Prevent stale responses from overwriting newer UI state
- Preserve responsive typing and scrolling during high activity
-
---
-
-### Non-goals
-
- Changing server-side behavior or adding new endpoints
- Implementing global request queues for all SDK calls
- Persisting search results across reloads
-
---
-
-### Current state
-
- File search calls `sdk.client.find.files` via `files.searchFilesAndDirectories`.
- LSP refresh is triggered frequently (exact call sites vary, but the refresh behavior is high-frequency).
- Large UI modules involved include `packages/app/src/pages/layout.tsx` and `packages/app/src/components/prompt-input.tsx`.
-
---
-
-### Proposed approach
-
- Add a small request coordinator utility:
-  - debounced triggering (leading/trailing configurable)
-  - cancellation via `AbortController` when supported
-  - stale-result protection via monotonic request ids when abort is not supported
- Integrate coordinator into:
-  - `files.searchFilesAndDirectories` (wrap `sdk.client.find.files`)
-  - LSP refresh call path (wrap refresh invocation and ensure only latest applies)
-
---
-
-### Phased implementation steps
-
-1. Add a debounced + cancellable helper
-
- Create `packages/app/src/utils/requests.ts` with:
-  - `createDebouncedAsync(fn, delayMs)`
-  - `createLatestOnlyAsync(fn)` that drops stale responses
- Prefer explicit, readable primitives over a single complex abstraction.
-
-Sketch:
-
-```ts
-function createLatestOnlyAsync<TArgs extends unknown[], TResult>(
-  fn: (args: { input: TArgs; signal?: AbortSignal }) => Promise<TResult>,
-) {
-  let id = 0
-  let controller: AbortController | undefined
-
-  return async (...input: TArgs) => {
-    id += 1
-    const current = id
-    controller?.abort()
-    controller = new AbortController()
-
-    const result = await fn({ input, signal: controller.signal })
-    if (current !== id) return
-    return result
-  }
-}
-```
-
-2. Apply to file search
-
- Update `files.searchFilesAndDirectories` to:
-  - debounce input changes (e.g. 150–300 ms)
-  - abort prior request when a new query begins
-  - ignore results if they are stale
- Ensure “empty query” is handled locally without calling the server.
-
-3. Apply to LSP refresh
-
- Identify the refresh trigger points used during typing and file switching.
- Add:
-  - debounce for rapid triggers (e.g. 250–500 ms)
-  - cancellation for in-flight refresh if supported
-  - last-write-wins behavior for applying diagnostics/results
-
-4. Add feature flags and metrics
-
- Add flags:
-  - `requests.debounce.fileSearch`
-  - `requests.latestOnly.lspRefresh`
- Add simple dev-only counters for “requests started / aborted / applied”.
-
---
-
-### Data migration / backward compatibility
-
- No persisted data changes.
- Behavior is compatible as long as UI state updates only when the “latest” request resolves.
-
---
-
-### Risk + mitigations
-
- Risk: aggressive debounce makes UI feel laggy.
-  - Mitigation: keep delays small and tune separately for search vs refresh.
- Risk: aborting requests may surface as errors in logs.
-  - Mitigation: treat `AbortError` as expected and do not log it as a failure.
- Risk: SDK method may not accept `AbortSignal`.
-  - Mitigation: use request-id stale protection even without true cancellation.
-
---
-
-### Validation plan
-
- Manual scenarios:
-  - type quickly in file search and confirm requests collapse and results stay correct
-  - trigger LSP refresh repeatedly and confirm diagnostics do not flicker backward
- Add a small unit test for latest-only behavior (stale results are ignored).
-
---
-
-### Rollout plan
-
- Ship helpers behind flags default off.
- Enable file search debounce first (high impact, easy to validate).
- Enable LSP latest-only next, then add cancellation if SDK supports signals.
- Keep a quick rollback by disabling the flags.
-
---
-
-### Open questions
-
- Does `sdk.client.find.files` accept an abort signal today, or do we need stale-result protection only?
- Where is LSP refresh initiated, and does it have a single chokepoint we can wrap?
- What debounce values feel best for common repos and slower machines?

-## Spy acceleration
-
-Replace O(N) DOM scans in session view
-
---
-
-### Summary
-
-The session scroll-spy currently scans the DOM with `querySelectorAll` and walks message nodes, which becomes expensive as message count grows. We’ll replace the scan with an observer-based or indexed approach that scales smoothly.
-
---
-
-### Goals
-
- Remove repeated full DOM scans during scroll in the session view
- Keep “current message” tracking accurate during streaming and layout shifts
- Provide a safe fallback path for older browsers and edge cases
-
---
-
-### Non-goals
-
- Visual redesign of the session page
- Changing message rendering structure or IDs
- Perfect accuracy during extreme layout thrash
-
---
-
-### Current state
-
- `packages/app/src/pages/session.tsx` uses `querySelectorAll('[data-message-id]')` for scroll-spy.
- The page is large and handles many responsibilities, increasing the chance of perf regressions.
-
---
-
-### Proposed approach
-
-Implement a two-tier scroll-spy:
-
- Primary: `IntersectionObserver` to track which message elements are visible, updated incrementally.
- Secondary: binary search over precomputed offsets when observer is unavailable or insufficient.
- Use `ResizeObserver` (and a lightweight “dirty” flag) to refresh offsets only when layout changes.
-
---
-
-### Phased implementation steps
-
-1. Extract a dedicated scroll-spy module
-
- Create `packages/app/src/pages/session/scroll-spy.ts` (or similar) that exposes:
-  - `register(el, id)` and `unregister(id)`
-  - `getActiveId()` signal/store
- Keep DOM operations centralized and easy to profile.
-
-2. Add IntersectionObserver tracking
-
- Observe each `[data-message-id]` element once, on mount.
- Maintain a small map of `id -> intersectionRatio` (or visible boolean).
- Pick the active id by:
-  - highest intersection ratio, then
-  - nearest to top of viewport as a tiebreaker
-
-3. Add binary search fallback
-
- Maintain an ordered list of `{ id, top }` positions.
- On scroll (throttled via `requestAnimationFrame`), compute target Y and binary search to find nearest message.
- Refresh the positions list on:
-  - message list mutations (new messages)
-  - container resize events (ResizeObserver)
-  - explicit “layout changed” events after streaming completes
-
-4. Remove `querySelectorAll` hot path
-
- Keep a one-time initial query only as a bridge during rollout, then remove it.
- Ensure newly rendered messages are registered via refs rather than scanning the whole DOM.
-
-5. Add a feature flag and fallback
-
- Add `session.scrollSpyOptimized` flag.
- If observer setup fails, fall back to the existing scan behavior temporarily.
-
---
-
-### Data migration / backward compatibility
-
- No persisted data changes.
- IDs remain sourced from existing `data-message-id` attributes.
-
---
-
-### Risk + mitigations
-
- Risk: observer ordering differs from previous “active message” logic.
-  - Mitigation: keep selection rules simple, document them, and add a small tolerance for tie cases.
- Risk: layout shifts cause incorrect offset indexing.
-  - Mitigation: refresh offsets with ResizeObserver and after message streaming batches.
- Risk: performance regressions from observing too many nodes.
-  - Mitigation: prefer one observer instance and avoid per-node observers.
-
---
-
-### Validation plan
-
- Manual scenarios:
-  - very long sessions (hundreds of messages) and continuous scrolling
-  - streaming responses that append content and change heights
-  - resizing the window and toggling side panels
- Add a dev-only profiler hook to log time spent in scroll-spy updates per second.
-
---
-
-### Rollout plan
-
- Land extracted module first, still using the old scan internally.
- Add observer implementation behind `session.scrollSpyOptimized` off by default.
- Enable flag for internal testing, then default on after stability.
- Keep fallback code for one release cycle, then remove scan path.
-
---
-
-### Open questions
-
- What is the exact definition of “active” used elsewhere (URL hash, sidebar highlight, breadcrumb)?
- Are messages virtualized today, or are all DOM nodes mounted at once?
- Which container is the scroll root (window vs an inner div), and does it change by layout mode?

---
-

-
---

- Deduplicate “scoped session cache” logic into a shared utility
- Make performance fixes (eviction, throttling) easier to implement safely
-
---
-
-### Non-goals
-
- Large redesign of routing or page structure
- Moving to a different state management approach
- Rewriting all contexts in one pass
-
---
-
-### Current state
-
- Session page is large and mixes concerns (`packages/app/src/pages/session.tsx`).
- Layout is also large and likely coordinates multiple global concerns (`packages/app/src/pages/layout.tsx`).
- Prompt input is large and includes persistence and interaction logic (`packages/app/src/components/prompt-input.tsx`).
- Similar “scoped cache” patterns appear in multiple places (session-bound maps, per-session stores, ad hoc memoization).
-
---
-
-### Proposed approach
-
- Introduce a shared “scoped store” utility to standardize session-bound caches:
-  - keyed by `sessionId`
-  - automatic cleanup via TTL or explicit `dispose(sessionId)`
-  - optional LRU cap for many sessions
- Break mega-components into focused modules with clear boundaries:
-  - “view” components (pure rendering)
-  - “controller” hooks (state + effects)
-  - “services” (SDK calls, persistence adapters)
-
---
-
-### Phased implementation steps
-
-1. Inventory and name the repeated pattern
-
- Identify the repeated “scoped session cache” usage sites in:
-  - `packages/app/src/pages/session.tsx`
-  - `packages/app/src/pages/layout.tsx`
-  - `packages/app/src/components/prompt-input.tsx`
- Write down the common operations (get-or-create, clear-on-session-change, dispose).
-
-2. Add a shared scoped-cache utility
-
- Create `packages/app/src/utils/scoped-cache.ts`:
-  - `createScopedCache(createValue, opts)` returning `get(key)`, `peek(key)`, `delete(key)`, `clear()`
-  - optional TTL + LRU caps to avoid leak-by-design
- Keep the API tiny and explicit so call sites stay readable.
-
-Sketch:
-
-```ts
-type ScopedOpts = { maxEntries?: number; ttlMs?: number }
-
-function createScopedCache<T>(createValue: (key: string) => T, opts: ScopedOpts) {
-  // store + eviction + dispose hooks
-}
-```
-
-3. Extract session page submodules
-
- Split `packages/app/src/pages/session.tsx` into:
-  - `session/view.tsx` for rendering layout
-  - `session/messages.tsx` for message list
-  - `session/composer.tsx` for input wiring
-  - `session/scroll-spy.ts` for active message tracking
- Keep exports stable so routing code changes minimally.
-
-4. Extract layout coordination logic
-
- Split `packages/app/src/pages/layout.tsx` into:
-  - shell layout view
-  - navigation/controller logic
-  - global keyboard shortcuts (if present)
- Ensure each extracted piece has a narrow prop surface and no hidden globals.
-
-5. Extract prompt-input state machine
-
- Split `packages/app/src/components/prompt-input.tsx` into:
-  - `usePromptComposer()` hook (draft, submission, attachments)
-  - presentational input component
- Route persistence through existing `packages/app/src/context/prompt.tsx`, but isolate wiring code.
-
-6. Replace ad hoc scoped caches with the shared utility
-
- Swap one call site at a time and keep behavior identical.
- Add a flag `scopedCache.shared` to fall back to the old implementation if needed.
-
---
-
-### Data migration / backward compatibility
-
- No persisted schema changes are required by modularization alone.
- If any cache keys change due to refactors, keep a compatibility reader for one release cycle.
-
---
-
-### Risk + mitigations
-
- Risk: refactors cause subtle behavior changes (focus, keyboard shortcuts, scroll position).
-  - Mitigation: extract without logic changes first, then improve behavior in later diffs.
- Risk: new shared cache introduces lifecycle bugs.
-  - Mitigation: require explicit cleanup hooks and add dev assertions for retained keys.
- Risk: increased file count makes navigation harder temporarily.
-  - Mitigation: use consistent naming and keep the folder structure shallow.
-
---
-
-### Validation plan
-
- Manual regression checklist:
-  - compose, attach images, submit, and reload draft
-  - navigate between sessions and confirm caches don’t bleed across IDs
-  - verify terminal, file search, and scroll-spy still behave normally
- Add lightweight unit tests for `createScopedCache` eviction and disposal behavior.
-
---
-
-### Rollout plan
-
- Phase 1: introduce `createScopedCache` unused, then adopt in one low-risk area.
- Phase 2: extract session submodules with no behavior changes.
- Phase 3: flip remaining scoped caches to shared utility behind `scopedCache.shared`.
- Phase 4: remove old duplicated implementations after confidence.
-
---
-
-### Open questions
-
- Where exactly is “scoped session cache” duplicated today, and what are the differing lifecycle rules?
- Which extracted modules must remain synchronous for Solid reactivity to behave correctly?
- Are there implicit dependencies in the large files (module-level state) that need special handling?

-# App i18n Audit (Remaining Work)
-
-Scope: `packages/app/`
-
-Date: 2026-01-20
-
-This report documents the remaining user-facing strings in `packages/app/src` that are still hardcoded (not routed through `useLanguage().t(...)` / translation keys), plus i18n-adjacent issues like locale-sensitive formatting.
-
-## Current State
-
- The app uses `useLanguage().t("...")` with dictionaries in `packages/app/src/i18n/en.ts` and `packages/app/src/i18n/zh.ts`.
- Recent progress (already translated): `packages/app/src/pages/home.tsx`, `packages/app/src/pages/layout.tsx`, `packages/app/src/pages/session.tsx`, `packages/app/src/components/prompt-input.tsx`, `packages/app/src/components/dialog-connect-provider.tsx`, `packages/app/src/components/session/session-header.tsx`, `packages/app/src/pages/error.tsx`, `packages/app/src/components/session/session-new-view.tsx`, `packages/app/src/components/session-context-usage.tsx`, `packages/app/src/components/session/session-context-tab.tsx`, `packages/app/src/components/session-lsp-indicator.tsx`, `packages/app/src/components/session/session-sortable-tab.tsx`, `packages/app/src/components/titlebar.tsx`, `packages/app/src/components/dialog-select-model.tsx`, `packages/app/src/context/notification.tsx`, `packages/app/src/context/global-sync.tsx`, `packages/app/src/context/file.tsx`, `packages/app/src/context/local.tsx`, `packages/app/src/utils/prompt.ts`, `packages/app/src/context/terminal.tsx`, `packages/app/src/components/session/session-sortable-terminal-tab.tsx` (plus new keys added in both dictionaries).
- Dictionary parity check: `en.ts` and `zh.ts` currently contain the same key set (373 keys each; no missing or extra keys).
-
-## Methodology
-
- Scanned `packages/app/src` (excluding `packages/app/src/i18n/*` and tests).
- Grepped for:
-  - Hardcoded JSX text nodes (e.g. `>Some text<`)
-  - Hardcoded prop strings (e.g. `title="..."`, `placeholder="..."`, `label="..."`, `description="..."`, `Tooltip value="..."`)
-  - Toast/notification strings, default fallbacks, and error message templates.
- Manually reviewed top hits to distinguish:
-  - User-facing UI copy (needs translation)
-  - Developer-only logs (`console.*`) (typically does not need translation)
-  - Technical identifiers (e.g. `MCP`, `LSP`, URLs) (may remain untranslated by choice).
-
-## Highest Priority: Pages
-
-### 1) Error Page
-
-File: `packages/app/src/pages/error.tsx`
-
-Completed (2026-01-20):
-
- Localized page UI copy via `error.page.*` keys (title, description, buttons, report text, version label).
- Localized error chain framing and common init error templates via `error.chain.*` keys.
- Kept raw server/provider error messages as-is when provided (only localizing labels and structure).

-
-File: `packages/app/src/components/prompt-input.tsx`
-
-Completed (2026-01-20):
-
- Localized placeholder examples by replacing the hardcoded `PLACEHOLDERS` list with `prompt.example.*` keys.
- Localized toast titles/descriptions via `prompt.toast.*` and reused `common.requestFailed` for fallback error text.

-File: `packages/app/src/context/terminal.tsx`
-
-Completed (2026-01-20):
-
- Terminal display labels are now rendered from a stable numeric `titleNumber` and localized via `terminal.title.*`.

-
-## Low Priority: Utils / Dev-Only Copy
-
-### 17) Default Attachment Filename
-
-File: `packages/app/src/utils/prompt.ts`
-
-Completed (2026-01-20):

-
-## Prioritized Implementation Plan
-
-No remaining work in `packages/app/` as of 2026-01-20.
-
-## Suggested Key Naming Conventions
-
-To keep the dictionaries navigable, prefer grouping by surface:
-
- `error.page.*`, `error.chain.*`
- `prompt.*` (including examples, tooltips, empty states, toasts)
- `provider.connect.*` (auth flow UI + validation + success)
- `session.share.*` (publish/unpublish/copy link)
- `context.usage.*` (Tokens/Usage/Cost + call to action)
- `lsp.*` (and potentially `mcp.*` if expanded)
- `notification.session.*`
- `toast.file.*`, `toast.session.*`
-
-Also reuse existing command keys for tooltip titles whenever possible (e.g. `command.sidebar.toggle`, `command.review.toggle`, `command.terminal.toggle`).

-# UI i18n Audit (Remaining Work)
-
-Scope: `packages/ui/` (and consumers: `packages/app/`, `packages/enterprise/`)
-
-Date: 2026-01-20
-
-This report documents the remaining user-facing strings in `packages/ui/src` that are still hardcoded (not routed through a translation function), and proposes an i18n architecture that works long-term across multiple packages.
-
-## Current State
-
- `packages/app/` already has i18n via `useLanguage().t("...")` with dictionaries in `packages/app/src/i18n/en.ts` and `packages/app/src/i18n/zh.ts`.
- `packages/ui/` is a shared component library used by:
-  - `packages/app/src/pages/session.tsx` (Session UI)
-  - `packages/enterprise/src/routes/share/[shareID].tsx` (shared session rendering)
- `packages/ui/` currently has **hardcoded English UI copy** in several components (notably `session-turn.tsx`, `session-review.tsx`, `message-part.tsx`).
- `packages/enterprise/` does not currently have an i18n system, so any i18n approach must be usable without depending on `packages/app/`.
-
-## Decision: How We Should Add i18n To `@opencode-ai/ui`
-
-Introduce a small, app-agnostic i18n interface in `packages/ui/` and keep UI-owned strings in UI-owned dictionaries.
-
-Why this is the best long-term shape:
-
- Keeps dependency direction clean: `packages/enterprise/` (and any future consumer) can translate UI without importing `packages/app/` dictionaries.
- Avoids prop-drilling strings through shared components.
- Allows each package to own its strings while still rendering a single, coherent locale in the product.
-
-### Proposed Architecture
-
-1. **UI provides an i18n context (no persistence)**
-
- Add `packages/ui/src/context/i18n.tsx`:
-  - Exports `I18nProvider` and `useI18n()`.
-  - Context value includes:
-    - `t(key, params?)` translation function (template interpolation supported by the consumer).
-    - `locale()` accessor for locale-sensitive formatting (Luxon/Intl).
-  - Context should have a safe default (English) so UI components can render even if a consumer forgets the provider.
-
-2. **UI owns UI strings (dictionaries live in UI)**
-
- Add `packages/ui/src/i18n/en.ts` and `packages/ui/src/i18n/zh.ts`.
- Export them from `@opencode-ai/ui` via `packages/ui/package.json` exports (e.g. `"./i18n/*": "./src/i18n/*.ts"`).
- Use a clear namespace prefix for all UI keys to avoid collisions:
-  - Recommended: `ui.*` (e.g. `ui.sessionReview.title`).
-
-3. **Consumers merge dictionaries and provide `t`/`locale` once**
-
- `packages/app/`:
-  - Keep `packages/app/src/context/language.tsx` as the source of truth for locale selection/persistence.
-  - Extend it to merge UI dictionaries into its translation table.
-  - Add a tiny bridge provider in `packages/app/src/app.tsx` to feed `useLanguage()` into `@opencode-ai/ui`'s `I18nProvider`.
-
- `packages/enterprise/`:
-  - Add a lightweight locale detector (similar to `packages/app/src/context/language.tsx`), likely based on `Accept-Language` on the server and/or `navigator.languages` on the client.
-  - Merge `@opencode-ai/ui` dictionaries and (optionally) enterprise-local dictionaries.
-  - Wrap the share route in `I18nProvider`.
-
-### Key Naming Conventions (UI)
-
- Prefer component + semantic grouping:
-  - `ui.sessionReview.title`
-  - `ui.sessionReview.diffStyle.unified`
-  - `ui.sessionReview.diffStyle.split`
-  - `ui.sessionReview.expandAll`
-  - `ui.sessionReview.collapseAll`
-
- For `SessionTurn`:
-  - `ui.sessionTurn.steps.show`
-  - `ui.sessionTurn.steps.hide`
-  - `ui.sessionTurn.summary.response`
-  - `ui.sessionTurn.diff.more` (use templating: `Show more changes ({{count}})`)
-  - `ui.sessionTurn.retry.retrying` / `ui.sessionTurn.retry.inSeconds` / etc (avoid string concatenation that is English-order dependent)
-  - Status text:
-    - `ui.sessionTurn.status.delegating`
-    - `ui.sessionTurn.status.planning`
-    - `ui.sessionTurn.status.gatheringContext`
-    - `ui.sessionTurn.status.searchingCode`
-    - `ui.sessionTurn.status.searchingWeb`
-    - `ui.sessionTurn.status.makingEdits`
-    - `ui.sessionTurn.status.runningCommands`
-    - `ui.sessionTurn.status.thinking`
-    - `ui.sessionTurn.status.thinkingWithTopic` (template: `Thinking - {{topic}}`)
-    - `ui.sessionTurn.status.gatheringThoughts`
-    - `ui.sessionTurn.status.consideringNextSteps` (fallback)
-
-## Locale-Sensitive Formatting (UI)
-
-`SessionTurn` currently formats durations via Luxon `Interval.toDuration(...).toHuman(...)` without an explicit locale.
-
-When i18n is added:
-
- Use `useI18n().locale()` and pass locale explicitly:
-  - Luxon: `duration.toHuman({ locale: locale(), ... })` (or set `.setLocale(locale())` where applicable).
-  - Intl numbers/currency (if added later): `new Intl.NumberFormat(locale(), ...)`.
-
-## Initial Hardcoded Strings (Audit Findings)
-
-These are the highest-impact UI surfaces to translate first.
-
-### 1) `packages/ui/src/components/session-review.tsx`
-
- `Session changes`
- `Unified` / `Split`
- `Collapse all` / `Expand all`
-
-### 2) `packages/ui/src/components/session-turn.tsx`
-
- Tool/task status strings (e.g. `Delegating work`, `Searching the codebase`)
- Steps toggle labels: `Show steps` / `Hide steps`
- Summary section title: `Response`
- Pagination CTA: `Show more changes ({{count}})`
-
-### 3) `packages/ui/src/components/message-part.tsx`
-
-Examples (non-exhaustive):
-
- `Error`
- `Edit`
- `Write`
- `Type your own answer`
- `Review your answers`
-
-### 4) Additional Hardcoded Strings (Full Audit)
-
-Found during a full `packages/ui/src/components` + `packages/ui/src/context` sweep:
-
- `packages/ui/src/components/list.tsx`
-  - `Loading`
-  - `No results`
-  - `No results for "{{filter}}"`
- `packages/ui/src/components/message-nav.tsx`
-  - `New message`
- `packages/ui/src/components/text-field.tsx`
-  - `Copied`
-  - `Copy to clipboard`
- `packages/ui/src/components/image-preview.tsx`
-  - `Image preview` (alt text)
-
-## Prioritized Implementation Plan
-
-1. Completed (2026-01-20): Add `@opencode-ai/ui` i18n context (`packages/ui/src/context/i18n.tsx`) + export it.
-2. Completed (2026-01-20): Add UI dictionaries (`packages/ui/src/i18n/en.ts`, `packages/ui/src/i18n/zh.ts`) + export them.
-3. Completed (2026-01-20): Wire `I18nProvider` into:
-   - `packages/app/src/app.tsx`
-   - `packages/enterprise/src/app.tsx`
-4. Completed (2026-01-20): Convert `packages/ui/src/components/session-review.tsx` and `packages/ui/src/components/session-turn.tsx` to use `useI18n().t(...)`.
-5. Completed (2026-01-20): Convert `packages/ui/src/components/message-part.tsx`.
-6. Completed (2026-01-20): Do a full `packages/ui/src/components` + `packages/ui/src/context` audit for additional hardcoded copy.
-
-## Notes / Risks
-
- **SSR:** Enterprise share pages render on the server. Ensure the i18n provider works in SSR and does not assume `window`/`navigator`.
- **Key collisions:** Use a consistent `ui.*` prefix to avoid clashing with app keys.
- **Fallback behavior:** Decide whether missing keys should:
-  - fall back to English, or
-  - render the key (useful for catching missing translations).

-## App E2E Smoke Suite (CI)
-
-Implement a small set of high-signal, low-flake Playwright tests to run in CI.
-
-These tests are intended to catch regressions in the “core shell” of the app (navigation, dialogs, prompt UX, file viewer, terminal), without relying on model output.
-
---
-
-### Summary
-
-Add 6 smoke tests to `packages/app/e2e/`:
-
- Settings dialog: open, switch tabs, close
- Prompt slash command: `/open` opens the file picker dialog
- Prompt @mention: `@<file>` inserts a file pill token
- Model picker: open model selection and choose a model
- File viewer: open a known file and assert contents render
- Terminal: open terminal, verify Ghostty mounts, create a second terminal
-
---
-
-### Progress
-
- [x] 1. Settings dialog open / switch / close (`packages/app/e2e/settings.spec.ts`)
- [x] 2. Prompt slash command path: `/open` opens file picker (`packages/app/e2e/prompt-slash-open.spec.ts`)
- [x] 3. Prompt @mention inserts a file pill token (`packages/app/e2e/prompt-mention.spec.ts`)
- [x] 4. Model selection UI works end-to-end (`packages/app/e2e/model-picker.spec.ts`)
- [x] 5. File viewer renders real file content (`packages/app/e2e/file-viewer.spec.ts`)
- [x] 8. Terminal init + create new terminal (`packages/app/e2e/terminal-init.spec.ts`)
-
---
-
-### Goals
-
- Tests run reliably in CI using the existing local runner (`packages/app/script/e2e-local.ts`).
- Cover “wiring” regressions across UI + backend APIs:
-  - dialogs + command routing
-  - prompt contenteditable parsing
-  - file search + file read + code viewer render
-  - terminal open + pty creation + Ghostty mount
- Avoid assertions that depend on LLM output.
- Keep runtime low (these should be “smoke”, not full workflows).
-
---
-
-### Non-goals
-
- Verifying complex model behavior, streaming correctness, or tool call semantics.
- Testing provider auth flows (CI has no secrets).
- Testing share, MCP, or LSP download flows (disabled in the e2e runner).
-
---
-
-### Current State
-
-Existing tests in `packages/app/e2e/` already cover:
-
- Home renders + server picker opens
- Directory route redirects to `/session`
- Sidebar collapse/expand
- Command palette opens/closes
- Basic session open + prompt input + (optional) prompt/reply flow
- File open via palette (but shallow assertion: tab exists)
- Terminal panel toggles (but doesn’t assert Ghostty mounted)
- Context panel open
-
-We want to add a focused smoke layer that increases coverage of the most regression-prone UI paths.
-
---
-
-### Proposed Tests
-
-All tests should use the shared fixtures in:
-
- `packages/app/e2e/fixtures.ts` (for `sdk`, `directory`, `gotoSession`)
- `packages/app/e2e/utils.ts` (for `modKey`, `promptSelector`, `terminalToggleKey`)
-
-Prefer creating new spec files rather than overloading existing ones, so it’s easy to run these tests as a group via grep.
-
-Suggested file layout:
-
- `packages/app/e2e/settings.spec.ts`
- `packages/app/e2e/prompt-slash-open.spec.ts`
- `packages/app/e2e/prompt-mention.spec.ts`
- `packages/app/e2e/model-picker.spec.ts`
- `packages/app/e2e/file-viewer.spec.ts`
- `packages/app/e2e/terminal-init.spec.ts`
-
-Name each test with a “smoke” prefix so CI can run only this suite if needed.
-
-#### 1) Settings dialog open / switch / close
-
-Purpose: catch regressions in dialog infra, settings rendering, tabs.
-
-Steps:
-
-1. `await gotoSession()`.
-2. Open settings via keybind (preferred for stability): `await page.keyboard.press(`${modKey}+Comma`)`.
-3. Assert dialog visible (`page.getByRole('dialog')`).
-4. Click the "Shortcuts" tab (role `tab`, name "Shortcuts").
-5. Assert shortcuts view renders (e.g. the search field placeholder or reset button exists).
-6. Close with `Escape` and assert dialog removed.
-
-Notes:
-
- If `Meta+Comma` / `Control+Comma` key name is flaky, fall back to clicking the sidebar settings icon.
- Favor role-based selectors over brittle class selectors.
- If `Escape` doesn’t dismiss reliably (tooltips can intercept), fall back to clicking the dialog overlay.
-
-Implementation: `packages/app/e2e/settings.spec.ts`
-
-Acceptance criteria:
-
- Settings dialog opens reliably.
- Switching to Shortcuts tab works.
- Escape closes the dialog.
-
-#### 2) Prompt slash command path: `/open` opens file picker
-
-Purpose: validate contenteditable parsing + slash popover + builtin command dispatch (distinct from `mod+p`).
-
-Steps:
-
-1. `await gotoSession()`.
-2. Click prompt (`promptSelector`).
-3. Type `/open`.
-4. Press `Enter` (while slash popover is active).
-5. Assert a dialog appears and contains a textbox (the file picker search input).
-6. Close dialog with `Escape`.
-
-Acceptance criteria:
-
- `/open` triggers `file.open` and opens `DialogSelectFile`.
-
-#### 3) Prompt @mention inserts a file pill token
-
-Purpose: validate the most fragile prompt behavior: structured tokens inside contenteditable.
-
-Steps:
-
-1. `await gotoSession()`.
-2. Focus the prompt.
-3. Type `@packages/app/package.json`.
-4. Press `Tab` to accept the active @mention suggestion.
-5. Assert a pill element is inserted:
-   - `page.locator('[data-component="prompt-input"] [data-type="file"][data-path="packages/app/package.json"]')` exists.
-
-Acceptance criteria:
-
- A file pill is inserted and has the expected `data-*` attributes.
- Prompt editor remains interactable (e.g. typing a trailing space works).
-
-#### 4) Model selection UI works end-to-end
-
-Purpose: validate model list rendering, selection wiring, and prompt footer updating.
-
-Implementation approach:
-
- Use `/model` to open the model selection dialog (builtin command).
-
-Steps:
-
-1. `await gotoSession()`.
-2. Focus prompt, type `/model`, press `Enter`.
-3. In the model dialog, pick a visible model that is not the current selection (if available).
-4. Use the search field to filter to that model (use its id from the list item's `data-key` to avoid time-based model visibility drift).
-5. Select the filtered model.
-6. Assert dialog closed.
-7. Assert the prompt footer now shows the chosen model name.
-
-Acceptance criteria:
-
- A model can be selected without requiring provider auth.
- The prompt footer reflects the new selection.
-
-#### 5) File viewer renders real file content
-
-Purpose: ensure file search + open + file.read + code viewer render all work.
-
-Steps:
-
-1. `await gotoSession()`.
-2. Open file picker (either `mod+p` or `/open`).
-3. Search for `packages/app/package.json`.
-4. Click the matching file result.
-5. Ensure the new file tab is active (click the `package.json` tab if needed so the viewer mounts).
-6. Assert the code viewer contains a known substring:
-   - `"name": "@opencode-ai/app"`.
-7. Optionally assert the file tab is active and visible.
-
-Acceptance criteria:
-
- Code view shows expected content (not just “tab exists”).
-
-#### 8) Terminal init + create new terminal
-
-Purpose: ensure terminal isn’t only “visible”, but actually mounted and functional.
-
-Steps:
-
-1. `await gotoSession()`.
-2. Open terminal with `terminalToggleKey` (currently `Control+Backquote`).
-3. Assert terminal container exists and is visible: `[data-component="terminal"]`.
-4. Assert Ghostty textarea exists: `[data-component="terminal"] textarea`.
-5. Create a new terminal via keybind (`terminal.new` is `ctrl+alt+t`).
-6. Assert terminal tab count increases to 2.
-
-Acceptance criteria:
-
- Ghostty mounts (textarea present).
- Creating a new terminal results in a second tab.
-

-
-### CI Stability + Flake Avoidance
-
-These tests run with `fullyParallel: true` in `packages/app/playwright.config.ts`. Keep them isolated and deterministic.
-
- Avoid ordering-based assertions: never assume a “first” session/project/file is stable unless you filtered by unique text.
- Prefer deterministic targets:
-  - use `packages/app/package.json` rather than bare `package.json` (multiple hits possible)
-  - for models, avoid hardcoding a single model id; pick from the visible list and filter by its `data-key` instead
- Prefer robust selectors:
-  - role selectors: `getByRole('dialog')`, `getByRole('textbox')`, `getByRole('tab')`
-  - stable data attributes already present: `promptSelector`, `[data-component="terminal"]`
- Keep tests local and fast:
-  - do not submit prompts that require real model replies
-  - avoid `page.waitForTimeout`; use `expect(...).toBeVisible()` and `expect.poll` when needed
- Watch for silent UI failures:
-  - capture `page.on('pageerror')` and fail test if any are emitted
-  - optionally capture console errors (`page.on('console', ...)`) and fail on `type==='error'`
- Cleanup:
-  - these tests should not need to create sessions
-  - if a test ever creates sessions or PTYs directly, clean up with SDK calls in `finally`
-
---
-
-### Validation Plan
-
-Run locally:
-
- `cd packages/app`
- `bun run test:e2e:local -- --grep smoke`
-
-Verify:
-
- all new tests pass consistently across multiple runs
- overall e2e suite time does not increase significantly
-
---
-
-### Open Questions
-
- Should we add a small helper in `packages/app/e2e/utils.ts` for “type into prompt contenteditable” to reduce duplication?
- Do we want to gate these smoke tests with a dedicated `@smoke` naming convention (or `test.describe('smoke', ...)`) so CI can target them explicitly?

-## Session page decomposition
-
-Split `pages/session.tsx` into focused modules without behavior changes.
-
---
-
-### Summary
-
-`packages/app/src/pages/session.tsx` is still a large (~3,655 LOC) route coordinator. Recent refactoring already extracted `packages/app/src/pages/session/helpers.ts` and `packages/app/src/pages/session/scroll-spy.ts`, but review-panel wiring, message timeline orchestration, file-tab rendering, and terminal coordination remain tightly coupled. This spec continues the decomposition from that updated baseline.
-
---
-
-### Goals
-
- Reduce complexity in `packages/app/src/pages/session.tsx`.
- Isolate major concerns into dedicated modules under `packages/app/src/pages/session/`.
- Keep behavior and route/API contracts unchanged.
- Preserve current keyboard, scroll, hash, and review interactions.
-
---
-
-### Non-goals
-
- No redesign of session UX.
- No changes to SDK contracts.
- No refactor of `context/global-sync.tsx`, `context/file.tsx`, or `components/prompt-input.tsx` in this workstream.
-
---
-
-### Parallel ownership (important)
-
-This workstream owns:
-
- `packages/app/src/pages/session.tsx`
- New files under `packages/app/src/pages/session/**`
-
-This workstream must not edit:
-
- `packages/app/src/pages/layout.tsx` (owned by spec 10)
- `packages/app/src/components/prompt-input.tsx` (owned by spec 11)
- `packages/app/src/context/global-sync.tsx` (owned by spec 12)
- `packages/app/src/context/file.tsx` (owned by spec 13)
-
---
-
-### Current state
-
- File size: ~3,655 LOC.
- Existing extracted modules:
-  - `packages/app/src/pages/session/helpers.ts` (terminal focus and shared handlers)
-  - `packages/app/src/pages/session/scroll-spy.ts` (message visibility + active-section tracking)
- High effect density (`createEffect`) and local-state density (`createStore` + `createSignal`) remain in `session.tsx`.
- Remaining interleaved responsibilities:
-  - review panel state + scrolling integration
-  - message timeline + hash navigation wiring
-  - file tab renderers + per-tab scroll sync
-  - terminal panel and tab coordination
-
---
-
-### Proposed module split
-
-Build on the existing `packages/app/src/pages/session/` directory and keep current extracted helpers in place. Add modules such as:
-
- `review-panel.tsx` - review tab rendering and focused diff logic.
- `message-timeline.tsx` - session turn rendering and active message tracking UI wiring.
- `file-tabs.tsx` - file tab content rendering, file scroll persistence, and line-comment overlays.
- `terminal-panel.tsx` - terminal tabs and focus behavior.
- `use-session-page-state.ts` - page-level derived state and imperative handlers.
-
-`packages/app/src/pages/session.tsx` remains the route entry and orchestrator only.
-
---
-
-### Phased steps
-
-1. Keep `helpers.ts` and `scroll-spy.ts` as baseline; extract any additional pure helpers first (no behavior changes).
-2. Extract review panel subtree and related handlers.
-3. Extract file-tab subtree and scroll synchronization logic.
-4. Extract terminal panel subtree.
-5. Move page-level state/effects into `use-session-page-state.ts`.
-6. Reduce `session.tsx` to composition and routing glue.
-
---
-
-### Acceptance criteria
-
- `packages/app/src/pages/session.tsx` is reduced substantially (target: under 1,400 LOC).
- No user-facing behavior changes in session, review, file tabs, or terminal tabs.
- Event listeners and observers are still correctly cleaned up.
- New modules have clear prop boundaries and minimal hidden coupling.
-
---
-
-### Validation plan
-
- Typecheck: `bun run typecheck` (from `packages/app`).
- Targeted e2e checks:
-  - `e2e/session/session.spec.ts`
-  - `e2e/files/file-viewer.spec.ts`
-  - `e2e/terminal/terminal.spec.ts`
- Manual checks:
-  - message hash navigation
-  - review diff focus + open-file action
-  - terminal tab create/reorder/focus behavior
-
---
-
-### Handoff notes
-
- Keep module interfaces narrow and data-oriented.
- Prefer extracting code unchanged before doing any cleanup refactors.
- If a helper is useful to other specs, place it under `pages/session/` for now; cross-spec shared utilities can be unified later.

-## Session hot paths
-
-Reduce render work and duplication in `session.tsx`
-
---
-
-### Summary
-
-`packages/app/src/pages/session.tsx` mixes routing, commands, tab rendering, review panel wiring, terminal focus logic, and message scrolling. This spec targets hot-path performance + local code quality improvements that can ship together in one session-page-focused PR. It should follow the keyed command-registration pattern introduced in `packages/app/src/context/command.tsx`.
-
---
-
-### Goals
-
- Render heavy file-tab content only for the active tab
- Deduplicate review-panel wiring used in desktop and mobile paths
- Centralize terminal-focus DOM logic into one helper
- Reduce churn in command registration setup
-
---
-
-### Non-goals
-
- Scroll-spy rewrite (covered by `specs/04-scroll-spy-optimization.md`)
- Large routing/layout redesign
- Behavior changes to prompt submission or session history
-
---
-
-### Parallel execution contract
-
-This spec owns:
-
- `packages/app/src/pages/session.tsx`
- New files under `packages/app/src/pages/session/*` (if extracted)

- `packages/app/src/context/*`
- `packages/app/src/components/prompt-input.tsx`
- `packages/app/src/components/file-tree.tsx`
-
---
-
-### Implementation plan
-
-1. Add shared helpers for repeated session-page actions
-
- Extract `openReviewFile(path)` helper to replace repeated inline `onViewFile` bodies.
- Extract `focusTerminalById(id)` helper and reuse in both:
-  - terminal active change effect
-  - terminal drag-end focus restoration
-
-2. Deduplicate review panel construction
-
- Build a shared review props factory (or local render helper) so desktop/mobile paths do not duplicate comment wiring, `onViewFile`, and classes glue.
- Keep per-surface differences limited to layout classes and diff style.
-
-3. Gate heavy file-tab rendering by active tab
-
- Keep tab trigger list rendered for all opened tabs.
- Render `Tabs.Content` body only for `activeTab()`, plus lightweight placeholders as needed.
- Ensure per-tab scroll state restore still works when reactivating a tab.
-
-4. Reduce command registry reallocation
-
- Register session commands with a stable key (`command.register("session", ...)`) so remounts replace prior session command entries.
- Move large command-array construction into smaller memoized blocks:
-  - stable command definitions
-  - dynamic state fields (`disabled`, titles) as narrow computed closures
-  - Keep command IDs, keybinds, and behavior identical.
-
---
-
-### Acceptance criteria
-
- File tab bodies are not all mounted at once for large open-tab sets.
- `onViewFile` review behavior is defined in one shared helper.
- Terminal focus query/dispatch logic lives in one function and is reused.
- Session command registration uses a stable key (`"session"`) and `command.register` no longer contains one monolithic inline array with repeated inline handlers for shared actions.
- Session UX remains unchanged for:
-  - opening files from review
-  - drag-reordering terminal tabs
-  - keyboard command execution
-
---
-
-### Validation plan
-
- Manual:
-  - Open 12+ file tabs, switch quickly, verify active tab restore and no blank states.
-  - Open review panel (desktop and mobile), use "view file" from diffs, verify same behavior as before.
-  - Drag terminal tab, ensure terminal input focus is restored.
-  - Run key commands: `mod+p`, `mod+w`, `mod+shift+r`, `ctrl+``.
- Perf sanity:
-  - Compare CPU usage while switching tabs with many opened files before/after.
-
---
-
-### Risks and mitigations
-
- Risk: unmounted tab content loses transient editor state.
-  - Mitigation: keep persisted scroll/selection restore path intact and verify reactivation behavior.
- Risk: command refactor subtly changes command ordering.
-  - Mitigation: keep IDs and registration order stable, diff against current command list in dev.

-## File cache accounting
-
-Make file-content eviction bookkeeping O(1)
-
---
-
-### Summary
-
-`packages/app/src/context/file.tsx` currently recomputes total cached bytes by reducing the entire LRU map inside the eviction loop. This creates avoidable overhead on large file sets. We will switch to incremental byte accounting while keeping LRU behavior unchanged.
-
---
-
-### Goals
-
- Remove repeated full-map reductions from eviction path
- Maintain accurate total byte tracking incrementally
- Preserve existing eviction semantics (entry count + byte cap)
-
---
-
-### Non-goals
-
- Changing cache limits
- Changing file loading API behavior
- Introducing cross-session shared caches
-
---
-
-### Parallel execution contract
-
-This spec owns:
-
- `packages/app/src/context/file.tsx`
- Optional tests in `packages/app/src/context/*file*.test.ts`
-
-This spec should not modify:
-
- `packages/app/src/pages/session.tsx`
- `packages/app/src/components/file-tree.tsx`
-
---
-
-### Implementation plan
-
-1. Introduce incremental byte counters
-
- Add module-level `contentBytesTotal`.
- Add helper(s):
-  - `setContentBytes(path, nextBytes)`
-  - `removeContentBytes(path)`
-  - `resetContentBytes()`
-
-2. Refactor LRU touch/update path
-
- Keep `contentLru` as LRU order map.
- Update byte total only when a path is inserted/updated/removed.
- Ensure replacing existing byte value updates total correctly.
-
-3. Refactor eviction loop
-
- Use `contentBytesTotal` in loop condition instead of `Array.from(...).reduce(...)`.
- On eviction, remove from both `contentLru` and byte counter.
-
-4. Keep scope reset correct
-
- On directory scope change, clear inflight maps + `contentLru` + byte counter.
-
---
-
-### Acceptance criteria
-
- `evictContent` performs no full-map reduction per iteration.
- Total bytes remain accurate after:
-  - loading file A
-  - loading file B
-  - force-reloading file A with a different size
-  - evicting entries
-  - scope reset
- Existing caps (`MAX_FILE_CONTENT_ENTRIES`, `MAX_FILE_CONTENT_BYTES`) continue to enforce correctly.
-
---
-
-### Validation plan
-
- Manual:
-  - Open many files with mixed sizes and verify old files still evict as before.
-  - Switch directory scope and verify cache clears safely.
- Optional unit coverage:
-  - size counter updates on overwrite + delete.
-  - eviction condition uses count and bytes as expected.
-
---
-
-### Risks and mitigations
-
- Risk: byte counter drifts from map contents.
-  - Mitigation: route all updates through centralized helpers.
- Risk: stale bytes retained on early returns.
-  - Mitigation: assert cleanup paths in `finally`/scope reset still execute.

-### Summary
-
-`packages/app/src/pages/layout.tsx` is a 3,000+ line coordinator for sidebar navigation, project/workspace controls, deep-link handling, dialogs, drag/drop overlays, and global shell interactions.

- Keep action handlers close to their domain module.
- Do not merge in behavior cleanups during extraction; preserve semantics first.
- If shared components are needed, add them under `pages/layout/` for now to avoid cross-spec conflicts.

-
-3. Keep return API stable
-
- Preserve current method names and behavior:

- Existing callers do not require API changes.
- Scroll restore and tab persistence still work across session navigation.
- No regressions in handoff/pending-message behavior.

-### Summary
-
-`packages/app/src/components/prompt-input.tsx` has already been partially decomposed and is now ~1,391 LOC. Editor DOM helpers, attachments, history, and submit flow were extracted into `packages/app/src/components/prompt-input/*.ts`, but optimistic mutation ownership and some UI/controller responsibilities are still split across call sites.

- Split `prompt-input.tsx` into modular UI + controller pieces.
- Centralize optimistic message add/remove behavior behind sync-context APIs.
- Remove unsafe cast path around optimistic parts (`as unknown as Part[]`).
- Keep existing prompt UX and submission semantics unchanged.
-
---

-  - `prompt-input/attachments.ts`
-  - `prompt-input/history.ts`
-  - `prompt-input/submit.ts`
- Optimistic mutation and request-part casting still need consolidation (including remaining `as unknown as Part[]` in submit path).
- Remaining concerns still tightly coupled in `prompt-input.tsx`:
-  - slash/mention UI rendering and keyboard orchestration
-  - context pill interactions and focus behavior
-  - composition glue across history/attachments/submit
-
---
-
-### Proposed structure
-
-Build on the existing `packages/app/src/components/prompt-input/` modules by adding/further splitting modules such as:
-
- `use-prompt-composer.ts` - state machine for submit/abort/history.
- `build-request-parts.ts` - typed request-part construction.
- `slash-popover.tsx` - slash command list rendering.
- `context-items.tsx` - context pills and interactions.
-
-Keep existing lower-level modules (`attachments.ts`, `editor-dom.ts`, `history.ts`, `submit.ts`) and narrow their responsibilities where needed.
-
-Add sync-level optimistic APIs (in `context/sync.tsx` or `context/sync-optimistic.ts`):
-
- `session.optimistic.add(...)`
- `session.optimistic.remove(...)`
-
-Prompt input should call these APIs instead of directly mutating message/part stores.
-
---
-
-### Phased steps
-
-1. Extract typed request-part builder (likely from `prompt-input/submit.ts`) to remove ad hoc casting.
-2. Introduce sync optimistic APIs with current behavior.
-3. Replace remaining direct `produce(...)` optimistic mutations with optimistic APIs.
-4. Extract remaining UI subtrees (slash popover, context items, toolbar controls).
-5. Extract controller hook and keep route component as composition shell.
-
---
-
-### Acceptance criteria
-
- Optimistic update logic exists in one place only.
- `prompt-input.tsx` is significantly smaller (target: under 1,200 LOC).
- Prompt submit/abort/history behavior remains unchanged.
- No `as unknown as Part[]` in optimistic request construction path.
-
---
-
-### Validation plan
-
- Typecheck: `bun run typecheck` (from `packages/app`).
- Targeted e2e checks:
-  - `e2e/prompt/prompt.spec.ts`
-  - `e2e/prompt/context.spec.ts`

- Manual check:
-  - submit with file/image/context attachments
-  - abort in-flight turn
-  - history up/down restore behavior
-
---
-
-### Handoff notes
-
- Preserve sequence semantics around optimistic insert, worktree wait, send, and rollback.
- Keep sync optimistic API data-oriented and reusable by future callers.
- Do not mix this with broader sync/global-sync refactors in the same diff.

- New files under `packages/app/src/context/global-sync/**`
-
-This workstream must not edit:

-
---
-
-### Current state
-
- Single large module with many responsibilities.
- Event reducer is embedded in component lifecycle code.
- Queue/scheduler, bootstrap, and child-store lifecycle are tightly interwoven.
-
---
-
-### Proposed module split
-
-Create `packages/app/src/context/global-sync/` modules like:
-
- `types.ts` - shared types.
- `queue.ts` - refresh queue and drain scheduler.
- `child-store.ts` - child store creation, persistence wiring, cache maps.
- `session-trim.ts` - pure session sorting/trimming helpers.
- `bootstrap.ts` - global and per-directory bootstrap flows.
- `event-reducer.ts` - event handlers for SDK event stream.
-
-Keep `global-sync.tsx` as provider/composition entry point.
-
---
-
-### Phased steps
-
-1. Extract pure helpers (`cmp`, session trim/recent logic) first.
-2. Extract queue/drain scheduler.
-3. Extract child-store creation and persisted cache wiring.
-4. Extract bootstrap flows.
-5. Extract event reducer and wire into existing listener.
-6. Keep API surface stable and documented.
-
---
-
-### Acceptance criteria
-
- Public API of `useGlobalSync()` remains backward compatible.
- `global-sync.tsx` is substantially reduced (target: under 500 LOC).
- Event handling logic is isolated and easier to trace.
- No behavior regressions in project/session/provider sync.
-
---
-
-### Validation plan
-
- Typecheck: `bun run typecheck` (from `packages/app`).
- Targeted e2e checks:

-  - `e2e/projects/projects-switch.spec.ts`
- Manual checks:
-  - switching directories/projects still hydrates child stores correctly
-  - session list/pagination behavior remains stable
-
---
-
-### Handoff notes
-
- Favor function extraction with unchanged code first.
- Keep event handler ordering explicit; avoid implicit fallthrough behaviors.
- Add focused tests only for extracted pure helpers if practical, but avoid broad test-suite changes here.

-## Context metrics shared
-
-Unify duplicate session usage calculations
-
---
-
-### Summary
-
-`session-context-tab.tsx` and `session-context-usage.tsx` both compute overlapping session metrics (cost, last assistant token totals, provider/model context usage). This creates duplicate loops and raises drift risk. We will centralize shared calculations in one helper module and have both components consume it.
-
---
-
-### Goals
-
- Compute shared session usage metrics in one place
- Remove duplicate loops for cost and latest-token context usage
- Keep UI output unchanged in both components
-
---
-
-### Non-goals
-
- Rewriting the detailed context breakdown estimator logic
- Changing translations or labels
- Moving metrics into backend API responses
-
---
-
-### Parallel execution contract
-
-This spec owns:
-
- `packages/app/src/components/session/session-context-tab.tsx`
- `packages/app/src/components/session-context-usage.tsx`
- New helper in `packages/app/src/components/session/*` or `packages/app/src/utils/*`
-
-This spec should not modify:
-
- `packages/app/src/pages/session.tsx`
- `packages/app/src/context/sync.tsx`
-
---
-
-### Implementation plan
-
-1. Add shared metrics helper
-
- Create helper for raw metrics from message list + provider map, e.g.:
-  - `totalCost`
-  - `lastAssistantWithTokens`
-  - `tokenTotal`
-  - `tokenUsagePercent`
-  - provider/model labels
- Return raw numeric values; keep locale formatting in consumers.
-
-2. Add memoization guard
-
- Use reference-based memoization (e.g. by message-array identity) inside helper or component-level memo to avoid duplicate recalculation on unchanged arrays.
-
-3. Migrate both components
-
- Replace duplicated loops in:
-  - `session-context-tab.tsx`
-  - `session-context-usage.tsx`
- Keep existing UI structure and i18n keys unchanged.
-
---
-
-### Acceptance criteria
-
- Shared cost + token calculations are defined in one module.
- Both components read from the shared helper.
- Rendered values remain identical for:
-  - total cost
-  - token totals
-  - usage percentage
-  - provider/model fallback labels
-
---
-
-### Validation plan
-
- Manual:
-  - Open session context tab and compare values with header/context indicator tooltip.
-  - Verify values update correctly while new assistant messages stream in.
- Regression:
-  - locale change still formats numbers/currency correctly.
-
---
-
-### Risks and mitigations
-
- Risk: helper changes semantic edge cases (no provider, no model, missing token fields).
-  - Mitigation: preserve existing fallback behavior (`"—"`, null percent).
- Risk: memoization over-caches stale values.
-  - Mitigation: key cache by message-array reference and dependent IDs only.

-## File context domain split
-
-Refactor `context/file.tsx` into focused modules with unchanged API.
-
---
-
-### Summary
-
-`packages/app/src/context/file.tsx` still combines path normalization, file-content caching/eviction, file-tree loading, watcher event handling, and file-view persistence orchestration. Recent refactoring extracted generic scoped-cache primitives to `packages/app/src/utils/scoped-cache.ts`, but most file-domain behavior remains in one module. This spec separates those concerns while preserving the existing `useFile()` interface.
-
---
-
-### Goals
-
- Keep `useFile()` API stable for all callers.
- Extract independent domains into dedicated modules.
- Improve readability and lower risk for future file-tree/perf changes.
- Preserve current caching and watcher semantics.
-
---
-
-### Non-goals
-
- No redesign of file tree UI.
- No change to backend file APIs.
- No simultaneous refactor of `components/file-tree.tsx` in this workstream.

-
---
-
-### Current state
-
- File size: ~751 LOC.
- `packages/app/src/utils/scoped-cache.ts` now exists as a shared cache primitive used by file view persistence.
- Multiple domains in one module:
-  - path normalization/parsing
-  - LRU content memory management
-  - tree node/directory state management
-  - event-driven watcher invalidation
-  - per-session view cache bootstrapping
-
---
-
-### Proposed module split
-
-Create `packages/app/src/context/file/` modules such as:
-
- `path.ts` - normalize/strip helpers.
- `content-cache.ts` - content LRU + byte caps.
- `view-cache.ts` - per-session file view persistence cache (building on `createScopedCache`).
- `tree-store.ts` - directory/node store and list/expand/collapse actions.
- `watcher.ts` - watcher event handling and invalidation routines.
-
-`file.tsx` remains the provider entry that composes these modules.
-
---
-
-### Phased steps
-
-1. Extract path helper functions with no behavior changes.
-2. Extract content cache and eviction logic.
-3. Extract file-specific view-cache loading/pruning logic on top of `createScopedCache`.
-4. Extract tree-store list/refresh/toggle actions.
-5. Extract watcher update handler and wire cleanup.
-6. Keep `useFile()` return shape unchanged.
-
---
-
-### Acceptance criteria
-
- `useFile()` API remains backward compatible.
- `context/file.tsx` is reduced significantly (target: under 350 LOC).
- Tree loading/refresh and content eviction behavior remain unchanged.
- Watcher-driven reload behavior still works for changed/added/deleted files.

- Typecheck: `bun run typecheck` (from `packages/app`).
- Targeted e2e checks:

- Manual checks:
-  - directory expand/collapse and refresh
-  - large file navigation and cache reuse
-  - watcher-driven updates in active file tabs
-
---
-
-### Handoff notes
-
- Keep tree/data stores colocated with their mutation helpers.
- Avoid changing persisted key names or cache key shapes in this pass.
- Save broader API cleanups for a follow-up once modules are stable.

-## File tree fetches
-
-Make directory listing triggers explicit and minimal
-
---
-
-### Summary
-
-`packages/app/src/components/file-tree.tsx` currently invokes `file.tree.list(path)` from a generic effect in each tree instance. Even with inflight guards, this pattern causes avoidable list calls and makes load behavior harder to reason about. This spec tightens fetch triggers.
-
---
-
-### Goals
-
- Avoid redundant list invocations from passive rerenders
- Fetch directory data only when needed (mount + expansion + explicit refresh)
- Keep tree behavior unchanged for users
-
---
-
-### Non-goals
-
- Replacing recursive tree rendering with virtualization
- Changing file-tree visual design
- Backend/API changes for file listing
-
---
-
-### Parallel execution contract
-
-This spec owns:
-
- `packages/app/src/components/file-tree.tsx`
-
-This spec should not modify:
-
- `packages/app/src/context/file.tsx`
- `packages/app/src/pages/session.tsx`
-
---
-
-### Implementation plan
-
-1. Replace broad list effect with explicit triggers
-
- Load root path on mount.
- For nested directories, list only when:
-  - node is expanded, or
-  - parent explicitly requests refresh.
-
-2. Guard expansion-driven fetches
-
- Keep `file.tree.expand(path)` as the primary source of truth for expansion fetches.
- Ensure passive rerenders do not retrigger `list(path)` calls for already loaded dirs.
-
-3. Keep filter auto-expand behavior
-
- Preserve existing "allowed filter" directory auto-expansion.
- Ensure auto-expanded directories still fetch exactly once unless force refresh occurs.
-
---
-
-### Acceptance criteria
-
- `file-tree.tsx` no longer calls `file.tree.list(path)` from an unscoped rerender effect.
- Expanding a folder still loads its children correctly.
- Filtering by `allowed` still opens and shows required parent directories.
- No regressions in change/all tabs where `FileTree` is used.
-
---
-
-### Validation plan
-
- Manual:
-  - Expand/collapse deep directory trees repeatedly.
-  - Switch between "changes" and "all" tree tabs.
-  - Open review, click files, verify tree stays responsive.
- Optional instrumentation:
-  - count list calls per user action and compare before/after.
-
---
-
-### Risks and mitigations
-
- Risk: directories fail to load when expansion timing changes.
-  - Mitigation: rely on `expand()` path and verify for root + nested nodes.
- Risk: filter-driven auto-expand misses one level.
-  - Mitigation: keep existing auto-expand iteration and add regression checks.

-## Comments indexing
-
-Avoid repeated flatten+sort for comment aggregates
-
---
-
-### Summary
-
-`packages/app/src/context/comments.tsx` derives `all` by flattening all file comment arrays and sorting on every change. This is simple but can become expensive with many comments. We will maintain an indexed aggregate structure incrementally.
-
---
-
-### Goals

- Keep `comments.list(file)` behavior unchanged
- Make `comments.all()` retrieval near O(1) for reads
- Preserve chronological ordering guarantees

-
-### Implementation plan
-
-1. Add aggregate index state
-
- Maintain `commentsByFile` (existing) plus an `allComments` array in chronological order.
- Keep both updated through the same mutator paths.
-
-2. Update mutators
-
- `add`: append new comment to file list and aggregate list.
- `remove`: remove from file list and aggregate list by id/file.
- `clear`: reset both structures and focus/active state.
-
-3. Simplify selectors
-
- `list(file)` reads file list directly.
- `all()` returns pre-indexed aggregate list without per-read flatten+sort.
-
---
-
-### Acceptance criteria
-
- `comments.all()` no longer flattens and sorts every reactive run.
- Comment order stays chronological by `time`.
- `add/remove/clear/focus/active` semantics remain unchanged.
-
---
-
-### Validation plan
-
- Manual:
-  - Add multiple comments across different files.
-  - Remove one comment and verify both file-level and global views update correctly.
-  - Submit prompt (which clears comments) and verify reset behavior.
- Optional unit test:
-  - add/remove/clear keeps aggregate ordering and integrity.
-
---
-
-### Risks and mitigations
-
- Risk: aggregate list and per-file lists diverge.
-  - Mitigation: funnel all writes through centralized mutators; avoid direct store writes elsewhere.
- Risk: ID collision edge cases.
-  - Mitigation: keep UUID creation unchanged and remove by `file + id` pair.

-### Summary
-
-Server health logic is duplicated across multiple files, and server row rendering/truncation logic is repeated in both the status popover and server dialog. This creates drift risk and inconsistent behavior. This spec centralizes health checks and row rendering while preserving existing UX.

- `isDisposable(value): value is { dispose(): void }`
- `hasSetOption(value): value is { setOption(...): void }`
-

-
-1. Refactor terminal helpers (`setOption`, disposal cleanups) to typed guards.
-2. Refactor speech recognition window access to typed constructor lookup.
-3. Replace `serialize.ts` `as any` internals with explicit local interface.
-4. Remove `dialog-select-model.tsx` `as any` trigger props cast via stricter generic typing.

-### Summary
-
-The app has broad translation coverage but still has maintainability gaps: locale dictionaries are typed as `Partial`, some non-English dictionaries contain English values for specific keys, and a few user-facing strings are still hardcoded in components/pages.

- Keep `en.ts` as source-of-truth key set.
-
-2. Fix known untranslated key values in non-English dictionaries.
-
-3. Localize scoped hardcoded strings by adding translation keys and using `language.t(...)`.
-
---
-
-### Phased steps
-
-1. Add/adjust shared locale typing pattern for parity safety.
-2. Update all locale files to satisfy stricter typing.
-3. Translate known English carry-over keys in non-English dictionaries.
-4. Replace hardcoded copy in:
-
- `components/dialog-custom-provider.tsx`
- `pages/directory-layout.tsx`
-
-5. Run typecheck and parity checks.
-
---
-
-### Acceptance criteria
-
- Locale files enforce full key parity against `en` (compile-time).
- No known English carry-over values remain for the targeted keys in non-English locales.
- Scoped hardcoded user-facing strings are replaced with translation keys.
- Typecheck passes.
-
---
-
-### Validation plan
-
- Typecheck: `bun run typecheck` (from `packages/app`).
- Grep sanity checks:
-  - targeted keys no longer English in non-English locales
-  - scoped files no longer contain hardcoded user-facing copy
- Manual spot checks in at least 2 locales (for example: `de`, `zh`).
-
---
-
-### Handoff notes
-
- Keep key naming consistent with existing conventions.
- Avoid broad copy changes outside scoped files to reduce review surface.
- If translation wording is uncertain, keep it simple and literal for now; quality passes can follow.

-## Terminal cache scope
-
-Clarify workspace-only terminal cache semantics
-
---
-
-### Summary
-
-`packages/app/src/context/terminal.tsx` accepts `(dir, session)` but currently keys cache entries as `${dir}:${WORKSPACE_KEY}`. The behavior is workspace-scoped, but the API shape suggests session-scoped caching. This spec aligns naming and implementation to avoid confusion and future bugs.
-
---
-
-### Goals
-
- Make terminal cache scope explicit (workspace-scoped)
- Remove misleading unused session-keying surface
- Preserve existing runtime behavior
-
---
-
-### Non-goals
-
- Changing terminal persistence behavior
- Moving terminals to per-session isolation
- UI changes to terminal tabs
-
---
-
-### Parallel execution contract
-
-This spec owns:
-
- `packages/app/src/context/terminal.tsx`
-
-This spec should not modify:
-
- `packages/app/src/pages/session.tsx`
- `packages/app/src/components/session/session-sortable-terminal-tab.tsx`
-
---
-
-### Implementation plan
-
-1. Rename internals for clarity
-
- Update internal function names/variables from session-oriented to workspace-oriented where applicable.
-
-2. Remove unused session cache-key parametering
-
- Simplify `load`/factory signatures so keying intent is explicit.
- Keep key format workspace-only by directory.
-
-3. Add inline documentation
-
- Add short comment near cache key creation clarifying why terminals are shared across sessions in the same workspace.
-
-4. Keep behavior stable
-
- Ensure active terminal, tab order, clone/new/close behavior remain unchanged.
-
---
-
-### Acceptance criteria
-
- No unused session-derived cache key logic remains.
- Code communicates workspace-scoped terminal lifecycle clearly.
- No functional changes to terminal operations.
-
---
-
-### Validation plan
-
- Manual:
-  - Create multiple terminals, navigate between sessions in same workspace, confirm state continuity.
-  - Switch workspace directory, confirm separate terminal state.
-
---
-
-### Risks and mitigations
-
- Risk: accidental behavior change to session-scoped terminals.
-  - Mitigation: keep cache key unchanged; refactor naming/signatures only.

-## Unit test foundation
-
-Establish reliable unit coverage for core app logic.
-
---
-
-### Summary
-
-`packages/app` is still e2e-first, but recent refactoring added a first wave of active source-unit tests (session helpers/scroll spy, prompt-input modules, file-tree, comments/layout/terminal/file context, and scoped-cache). This spec focuses on turning that momentum into a stable, explicit unit-test baseline in CI/local and unblocking the remaining skipped legacy suites.
-
---
-
-### Goals
-
- Add a clear unit-test command for app source tests.
- Unskip and stabilize existing skipped unit tests.
- Add fast tests for high-value pure logic.
- Keep unit suite independent of full e2e environment.
-
---
-
-### Non-goals
-
- No replacement of e2e tests.
- No broad product-code refactors unless required to make logic testable.
- No flaky browser-automation tests added here.
-
---
-
-### Parallel ownership (important)
-
-This workstream owns:
-
- `packages/app/package.json` (test scripts only)
- `packages/app/happydom.ts` (if harness tweaks are needed)
- `packages/app/src/**/*.test.ts`
- `packages/app/src/**/*.test.tsx`
-
-This workstream should avoid editing product code files owned by other specs, unless a tiny testability export is strictly required.
-
---
-
-### Current state
-
- Active unit coverage now exists across several `src/**/*.test.*` files (including context, pages/session, components/prompt-input, and utils).
- Remaining skipped legacy suites:
-  - `src/context/layout-scroll.test.ts` (`test.skip`)
-  - `src/addons/serialize.test.ts` (`describe.skip`)
- `package.json` scripts still focus on Playwright e2e and do not expose a dedicated `test:unit` entrypoint.
-
---
-
-### Proposed approach
-
-1. Add dedicated unit-test script(s), for example:
-
- `test:unit` using Bun test + happydom preload where needed.
-
-2. Unskip and stabilize remaining skipped legacy tests:
-
- make `layout-scroll.test.ts` deterministic
- enable a reliable subset of `serialize.test.ts` (or split smoke vs heavy integration cases)
-
-3. Add/expand fast unit tests for high-value pure logic not yet covered:
-
- keybind parsing/formatting/matching (`context/command.tsx` exports)
- worktree state machine (`utils/worktree.ts`)
-
---
-
-### Phased steps
-
-1. Wire `test:unit` in `package.json`.
-2. Make existing skipped tests runnable and stable.
-3. Add at least 2 new unit test files for core pure logic.
-4. Ensure unit suite can run standalone without Playwright server setup.
-
---
-
-### Acceptance criteria
-
- `bun run test:unit` exists and passes locally.
- No full-file `describe.skip`/`test.skip` remains in `packages/app/src/**/*.test.*` (unless documented as intentionally quarantined with reason).
- Unit suite includes meaningful assertions for keybind + worktree logic.
- Runtime for unit suite remains fast (target: under 15 seconds locally, excluding first install).
-
---
-
-### Validation plan
-
- Run: `bun run test:unit`.
- Run: `bun run typecheck`.
- Verify unit tests can execute without starting full app/backend servers.
-
---
-
-### Handoff notes
-
- Keep tests implementation-focused, not duplicated business logic.
- Avoid mocks where practical; prefer real small-scope code paths.
- If integration-heavy serialize cases remain flaky, separate them into a clearly named non-default test target.

-## Performance roadmap
-
-Sequenced delivery plan for app scalability + maintainability
-
---
-
-### Objective
-
-Deliver the top 5 app improvements (performance + long-term flexibility) in a safe, incremental sequence that:
-
- minimizes regression risk
- keeps changes reviewable (small PRs)
- provides escape hatches (flags / caps)
- validates improvements with targeted measurements
-
-This roadmap ties together:
-
- `specs/01-persist-payload-limits.md`
- `specs/02-cache-eviction.md`
- `specs/03-request-throttling.md`
- `specs/04-scroll-spy-optimization.md`
- `specs/05-modularize-and-dedupe.md`
-
---
-
-### Guiding principles
-
- Prefer “guardrails first”: add caps/limits and do no harm, then optimize.
- Always ship behind flags if behavior changes (especially persistence and eviction).
- Optimize at chokepoints (SDK call wrappers, storage wrappers, scroll-spy module) instead of fixing symptoms at every call site.
- Make “hot paths” explicitly measurable in dev (e.g. via `packages/app/src/utils/perf.ts`).
-
---
-
-### Phase 0 — Baseline + flags (prep)
-
-**Goal:** make later changes safe to land and easy to revert.
-
-**Deliverables**
-
- Feature-flag plumbing for:
-  - persistence payload limits (`persist.payloadLimits`)
-  - request debouncing/latest-only (`requests.*`)
-  - cache eviction (`cache.eviction.*`)
-  - optimized scroll spy (`session.scrollSpyOptimized`)
-  - shared scoped cache (`scopedCache.shared`)
- Dev-only counters/logs for:
-  - persist oversize detections
-  - request aborts/stale drops
-  - eviction counts and retained sizes
-  - scroll-spy compute time per second
-
-**Exit criteria**
-
- Flags exist but default “off” for behavior changes.
- No user-visible behavior changes.
-
-**Effort / risk**: `S–M` / low
-
---
-
-### Phase 1 — Stop the worst “jank generators” (storage + request storms)
-
-**Goal:** remove the highest-frequency sources of main-thread blocking and redundant work.
-
-**Work items**
-
- Implement file search debounce + stale-result protection
-  - Spec: `specs/03-request-throttling.md`
-  - Start with file search only (lowest risk, easy to observe).
- Add persistence payload size checks + warnings (no enforcement yet)
-  - Spec: `specs/01-persist-payload-limits.md`
-  - Focus on detecting oversized keys and preventing repeated write attempts.
- Ship prompt-history “strip image dataUrl” behind a flag
-  - Spec: `specs/01-persist-payload-limits.md`
-  - Keep image metadata placeholders so UI remains coherent.
-
-**Exit criteria**
-
- Fast typing in file search generates at most 1 request per debounce window.
- Oversize persisted keys are detected and do not cause repeated blocking writes.
- Prompt history reload does not attempt to restore base64 `dataUrl` on web when flag enabled.
-
-**Effort / risk**: `M` / low–med
-
---
-
-### Phase 2 — Bound memory growth (in-memory eviction)
-
-**Goal:** stabilize memory footprint for long-running sessions and “project hopping”.
-
-**Work items**
-
- Introduce shared LRU/TTL cache helper
-  - Spec: `specs/02-cache-eviction.md`
- Apply eviction to file contents cache first
-  - Spec: `specs/02-cache-eviction.md`
-  - Pin open tabs / active file to prevent flicker.
- Add conservative eviction for global-sync per-directory child stores
-  - Spec: `specs/02-cache-eviction.md`
-  - Ensure evicted children are fully disposed.
- (Optional) session/message eviction if memory growth persists after the above
-  - Spec: `specs/02-cache-eviction.md`
-
-**Exit criteria**
-
- Opening many files does not continuously increase JS heap without bound.
- Switching across many directories does not keep all directory stores alive indefinitely.
- Eviction never removes currently active session/file content.
-
-**Effort / risk**: `M–L` / med
-
---
-
-### Phase 3 — Large session scroll scalability (scroll spy)
-
-**Goal:** keep scrolling smooth as message count increases.
-
-**Work items**
-
- Extract scroll-spy logic into a dedicated module (no behavior change)
-  - Spec: `specs/04-scroll-spy-optimization.md`
- Implement IntersectionObserver tracking behind flag
-  - Spec: `specs/04-scroll-spy-optimization.md`
- Add binary search fallback for non-observer environments
-  - Spec: `specs/04-scroll-spy-optimization.md`
-
-**Exit criteria**
-
- Scroll handler no longer calls `querySelectorAll('[data-message-id]')` on every scroll tick.
- Long sessions (hundreds of messages) maintain smooth scrolling.
- Active message selection remains stable during streaming/layout shifts.
-
-**Effort / risk**: `M` / med
-
---
-
-### Phase 4 — “Make it easy to keep fast” (modularity + dedupe)
-
-**Goal:** reduce maintenance cost and make future perf work cheaper.
-
-**Work items**
-
- Introduce shared scoped-cache utility and adopt in one low-risk area
-  - Spec: `specs/05-modularize-and-dedupe.md`
- Incrementally split mega-components (one PR per extraction)
-  - Spec: `specs/05-modularize-and-dedupe.md`
-  - Prioritize extracting:
-    - session scroll/backfill logic
-    - prompt editor model/history
-    - layout event/shortcut wiring
- Remove duplicated patterns after confidence + one release cycle
-
-**Exit criteria**
-
- Each mega-file drops below a target size (suggestion):
-  - `session.tsx` < ~800 LOC
-  - `prompt-input.tsx` < ~900 LOC
- “Scoped cache” has a single implementation used across contexts.
- Future perf fixes land in isolated modules with minimal cross-cutting change.
-
-**Effort / risk**: `L` / med–high
-
---
-
-### Recommended PR slicing (keeps reviews safe)
-
- PR A: add request helpers + file search debounce (flagged)
- PR B: persist size detection + logs (no behavior change)
- PR C: prompt history strip images (flagged)
- PR D: cache helper + file content eviction (flagged)
- PR E: global-sync child eviction (flagged)
- PR F: scroll-spy extraction (no behavior change)
- PR G: optimized scroll-spy implementation (flagged)
- PR H+: modularization PRs (small, mechanical refactors)
-
---
-
-### Rollout strategy
-
- Keep defaults conservative and ship flags “off” first.
- Enable flags internally (dev builds) to gather confidence.
- Flip defaults in this order:
-  1. file search debounce
-  2. prompt-history image stripping
-  3. file-content eviction
-  4. global-sync child eviction
-  5. optimized scroll-spy
-
---
-
-### Open questions
-
- What are acceptable defaults for storage caps and cache sizes for typical OpenCode usage?
- Does the SDK support `AbortSignal` end-to-end for cancellation, or do we rely on stale-result dropping?
- Should web and desktop persistence semantics be aligned (even if desktop has async storage available)?
