# Roadmap

> **Status (2026-07-13):** ALL of Wave 1-5 (11 items) implemented + committed on `develop` — see docs/PROGRESS_LOG.md for per-feature commits. Remaining: only the deferred backlog table (smaller, several now cheap on the shipped PTY-inject + approval-preview primitives).

Prioritized backlog of features to build next, derived from a grounded analysis of
the codebase + the existing planning docs (5 exploration lenses → 24 candidates →
this synthesis). Each item keeps **what it touches** (real files/subsystems) and a
rough **effort** so it's actionable, not aspirational.

**The throughline:** the product already *captures* everything — Claude Code hooks,
statusLine telemetry, the activity timeline, git diff, live-sessions — but under-*acts*
on it. The highest-leverage work turns passive capture into a **trustworthy remote
review-and-drive surface**, without touching the byte-shuttle. Two small primitives
unlock a whole family of features: a **server-side PTY-inject** call and a **preview on
the approval bar**.

Effort key: **S** ≈ 1–2 days · **M** ≈ 3–4 days · **L** ≈ 1–2 weeks. Order = suggested
build sequence (dependencies noted).

---

## Recently shipped (context)
- **Split-grid watch board (v0.8, desktop)** — 1×2/1×3/2×2/2×3 layouts, click-to-focus,
  per-quadrant inline approve / maximize / read-only monitor, drag-to-quadrant,
  resizable splitters, saved presets. (`public/grid-layout.ts`, `grid-presets.ts`,
  `cell-monitor.ts`, `tabs.ts`.)
- **Fixed:** browser worktree-create was 400ing (frontend sent `repoPath`, server reads
  `path`); now aligned + regression-tested (`public/projects.ts`, `test/worktree-form.test.ts`).

---

## Wave 1 — ship first (high-trust / high-delight, independent)

- [x] **Approval preview — see-what-you-approve** ⭐ _(strongest)_
  Show the pending `Bash` command or `Edit`/`Write` diff *above* Approve/Reject, so remote
  one-tap approval stops being blind (today you could tap Approve on `rm -rf build`).
  *The core walk-away trust gap.*
  **Touches:** `src/http/hook.ts` (`tool_input` is already parsed at `:104` — derive a
  bounded preview for Bash/Edit/Write/MultiEdit) → `/hook/permission` + `pendingApprovals`
  in `src/server.ts:423` (attach + re-send to late joiners, like `gate` already does) →
  optional bounded `preview` on the `status` ServerMessage in `src/types.ts` → `manager`
  → approval bar in `public/tabs.ts` (reuse `public/diff.ts` renderer + `sanitizeField`).
  Pure side-channel. **Effort: M.** Risk: truncate + strip control chars + cap bytes,
  `textContent`/diff-render only, unknown tools fall back to today's name-only bar.

- [x] **Clickable URLs & file paths in the terminal**
  Tap the dev-server URL or file path Claude prints instead of soft-keyboard copy gymnastics
  (paths reuse `POST /open-in-editor`). TECH_DOC named `@xterm/addon-web-links` in v0.2; never built.
  **Touches:** frontend only — `public/terminal-session.ts` (add the addon + a path-matcher
  regex → `/open-in-editor`). Zero server change. **Effort: S.**

---

## Wave 2 — the unlocking primitive

- [x] **Server-side PTY-inject + queued follow-up prompt** _(unlocks a family)_
  A thin Origin/loopback-guarded route that writes text into a session's PTY, plus a
  per-session queue that fires one entry when Claude goes idle ("now run the tests", then
  "now open a PR"). Walk-away = give a task and leave; queuing lets the session advance itself.
  **Touches:** new `POST /live-sessions/:id/queue` calling the existing `writeInput`
  (`src/session/session.ts:201`); a small queue in `manager.ts`; dequeue in the existing
  Stop/SessionEnd hook branch (`src/server.ts:414`); FE near `public/quick-reply.ts`.
  Injection is identical to a keystroke → byte-shuttle preserved, broadcasts to mirrors.
  **Effort: M.** Risk: gate firing on `claudeStatus==='idle'` + settle delay; surface the
  queue in UI. **Foundation for** templated launches, auto-continue, issue-intake (backlog).

---

## Wave 3 — read-only side-channel batch (review from the phone)

- [x] **Diff against a base branch** (`?base=<rev>`)
  Review a whole agent branch vs `main` before landing, not just uncommitted changes.
  `src/http/diff.ts` already deferred this (FR-B1.9) and named its mitigation:
  `git rev-parse --verify` allow-list before any revision reaches the CLI.
  **Touches:** optional `base` on `getDiff()` (guarded `git rev-parse --verify <base>` +
  trailing `--`, then `git diff <base>...`); branch-picker in `public/diff.ts`. **Effort: S/M.**

- [x] **PR + CI/checks status via `gh`** (read-only)
  Per-project/session chip: PR state · checks passing · mergeable — glance from the phone,
  re-engage only when red. No `gh` usage exists in `src/` yet; `gh` emits JSON (no parsing pain).
  **Touches:** new `src/http/gh.ts` (mirror `diff.ts`'s `runGit`); `GET /projects/pr?path=`
  guarded by `isValidGitDir`; `PrStatus` in `src/types.ts`; FE chip in project detail.
  Capability-probe + empty-degrade when `gh` absent/unauthed. **Effort: M.**

- [x] **Quick wins** (small, cheap, high-delight)
  - [ ] **Sync chip on project cards** — ahead/behind + last-commit, folded into the existing
    per-repo metadata pass in `src/http/projects.ts` (no new route). **S.**
  - [ ] **Cost budget guard + push alert** — `costUsd` already flows via statusLine
    (`handleStatusLine`); add `COST_BUDGET_USD` + a one-shot latch (like `stuckNotified`) +
    warn styling in `public/preview-grid.ts`. The rail that makes unattended auto-continue safe. **S–M.**
  - [ ] **"While you were away" reconnect digest** — read-side aggregate over `manager.list()`
    + telemetry/timeline/status → "3 done, 1 waiting, $6, 2 PRs" on reconnect. **S–M.**
  - [ ] **Recent-commits log per project** — `git log --oneline -n N` (NUL-delimited) via a
    guarded `GET /projects/log`; inert-text render. **S–M.**

---

## Wave 4 — close the git loop

- [x] **Worktree lifecycle: remove / prune** (create is now fixed)
  Delete losing worktrees + land the winner from any device — closes the create-only loop.
  **Touches:** `removeWorktree`/`pruneWorktrees` in `src/http/worktrees.ts` (same execFile
  no-shell + timeout, validate target in `git worktree list` & not main, reuse realpath
  containment); `DELETE /projects/worktree` + `POST /projects/worktree/prune` (Origin-guarded);
  make the existing `locked`/`prunable` tags actionable. **Effort: S–M.** Risk: destructive —
  require `--force` + confirm for dirty trees, reject the main worktree, safe error messages.

- [x] **Stage / commit / push from the diff viewer**
  Claude's done, you reviewed on the phone — now commit + push without typing git into a
  mobile terminal. Highest-risk git write; bound the MVP to per-file stage-toggle + commit +
  push-current-branch only; **defer discard/checkout**; realpath-contain paths, cap msg length,
  push only to existing upstream or `-u`, CSRF-guarded. **Effort: M–L.**

---

## Wave 5 — bigger bets

- [x] **Worktree fan-out board** _(the north star: 真并行不互踩)_
  Fan one task across N branch/agent lanes of one repo, watch them race, approve/kill per lane,
  keep the winner. **Mostly composition of shipped parts** — `createWorktree` + live-sessions +
  the split-grid watch board + statusLine gauges + per-quadrant inline approve; server side is a
  thin "sessions grouped by repo/worktree" endpoint. Cost is UI. **Effort: L.** Depends on Wave 4.

- [x] **App-level access token** (leave-the-LAN bar-raiser) — shipped on `develop`
  A constant-time-compared (`crypto.timingSafeEqual` over SHA-256, fixed-length guard)
  `WEBTERM_TOKEN` checked on the WS handshake (alongside, not replacing, Origin) + a central
  gate over every remote HTTP route, set as an `HttpOnly; SameSite=Strict; Secure-when-https`
  cookie after one-time `GET /?token=` or `POST /auth` (rate-limited 10/min/IP), disabled when
  unset (keeps LAN zero-config byte-identical). Charset/length-validated at load; loopback
  `/hook*` ingest exempt. `src/http/auth.ts` + wiring in `src/server.ts`.
  **Honest tradeoff:** a bar-raiser, **not** a TLS/Tailscale substitute — on bare `ws://` the
  token is cleartext and replayable; only hardens the TLS-terminated relay/tunnel path. **Effort: M.**

- [x] **Android Projects / Diff / Worktree screens** (client parity)
  Android's whole v0.6/v0.7 projects-git UI is SDK-gated/off in `settings.gradle.kts`.
  Zero server change (the `:api-client` module already speaks the endpoints), but the largest
  scope. Sequence *after* the server-side git features so it's one parity pass. **Effort: L.**

## Deferred backlog (your own recorded intent, surfaced from the docs)

Consciously punted in the planning docs; several become cheap once the two unlocking primitives
(PTY-inject, approval-preview) land.

| Feature | Deferred in | Note |
|---|---|---|
| Line-level review comments → agent | `FEATURE_WALKAWAY_WORKBENCH.md §B1.6 / US-B1.4` | Tap a diff line, type feedback, composed with `file:line` and sent via `TerminalSession.send`. No new route. Pairs with diff-vs-base. **M.** |
| GitHub issue → new session/worktree | `FEATURE_PROJECT_MANAGER.md §9` | Pick an issue → spawn a session (optionally fresh worktree) with title+body as the prompt. Rides PTY-inject + host `gh`. Treat issue text as untrusted bytes. **M.** |
| Templated one-tap launches (repo + prompt + mode) | implied by `attach.cwd` + Projects launchers | "Triage repo X in plan mode" as one tap. Rides PTY-inject + a template store. **M.** |
| Auto-continue on idle (bounded) | no idle automation today | Opt-in auto-inject "continue" up to N times under a cost ceiling. Rides PTY-inject + budget guard. Build last, low default cap, never auto-approve. **S–M.** |
| Cross-session cost rollup / trends | `FEATURE_WALKAWAY_WORKBENCH.md §B2.6` | Bounded ring beside the latest-only field + `GET /telemetry/summary` + dashboard panel. Overlaps the budget-guard quick win. **M.** |
| Mission Control: cross-session feed + durable run log | (no cockpit persistence today) | Merged reverse-chron feed + append-only on-disk tail (reuse `subscription-store.ts` JSONL/atomic write, byte-capped) so overnight runs survive restart. The "while you were away" digest is its first slice. **M–L.** |
| Per-project task backlog | task tracking unbuilt | Per-repo TODO store mirroring `prefs-store.ts`; one tap spawns Claude pre-filled. Local state, **not** a GitHub Issues sync (YAGNI). **M.** |
| Host tmux session discovery + attach | user request (this is not raw-iTerm; needs tmux) | We already run as a tmux client on the user's default tmux server (sessions `web_<id>`), so `tmux ls` already sees manual/iTerm tmux sessions. Add a discovery list + "attach external tmux session" entry in the launcher → spawn a client PTY `tmux attach -t <name>`, wrapped in the session model. **S–M.** |
