# 14 — Milestones (M0–M7)

Phased delivery. Each milestone ends with a **demo** (on-device where noted) and
has explicit **acceptance criteria**. Work top-to-bottom; don't skip M0/M1.

---

## M0 — Toolchain & scaffolding
**Goal:** everything builds; the plugin is discoverable; the repo is safe.
- [ ] Install JDK 17, Android SDK, set `ANDROID_HOME` (`12-toolchain.md`).
- [ ] `cd hermes-agent && uv sync` (hermes venv works).
- [ ] Create monorepo scaffold (`02-monorepo.md`): `gateway-plugin/`, `app/`
      (CMP: `shared`, `androidApp`, `desktopApp`), root `.gitignore`
      (**excludes `hermes-agent/`**), root `README.md`.
- [ ] `git init` + a pre-commit/CI guard that fails if `hermes-agent/` is staged.
- [ ] CMP project builds empty: `./gradlew :androidApp:assembleDebug`,
      `./gradlew :desktopApp:run` (blank window).
- [ ] Plugin skeleton: `plugin.yaml` + `adapter.py` with `register(ctx)` + a
      no-op `AndroidAdapter` → `hermes gateway status` lists **android**.
- **Demo:** `hermes gateway status` shows `android`; `./gradlew
  :androidApp:installDebug` installs a blank app on the MIX 2S.
- **Accept:** blank app installs + launches on-device; plugin visible in
  `hermes gateway status`; `hermes-agent/` is git-ignored (verify with
  `git status --ignored`).

## M1 — Gateway core loop (text round-trip)
**Goal:** pair + send a text message + get a (non-streaming) reply.
- [ ] WS server (`ws_server.py`): bind, `hello` auth (constant-time),
      `hello.ack`, heartbeat, connection registry.
- [ ] `AndroidAdapter.send()` → `message` frame; inbound `message.send` →
      `MessageEvent` → `handle_message`.
- [ ] Pairing store + `ANDROID_TOKEN`; QR payload in `interactive_setup`.
- [ ] App: Connect screen (URL+token, real `hello` test), `GatewayClient`
      (connect + reconnect), ChatScreen sends + renders `message`.
- [ ] `ws_probe.py` harness drives a real turn.
- **Demo (on-device):** pair the phone, send "hello", see the agent's reply.
- **Accept:** text round-trip works on-device; wrong token is rejected;
  reconnect after gateway restart re-pairs.

## M2 — Streaming + reasoning + tools + commentary
**Goal:** the "agent transparency" features.
- [ ] Map consumer `send`/`edit_message` → `message.start/update/stop`.
- [ ] Reasoning: set `show_reasoning` for android; adapter splits prefix →
      `reasoning` field. **Verify format with `ws_probe.py`.**
- [ ] Tool events: classify tool-progress `send()`s → structured
      `tool.start/progress/end` (turn-state machine). **Verify with probe.**
- [ ] Commentary → `commentary` frames. Typing → `typing`.
- [ ] App: live bubble (coalesced updates), `ReasoningBlock` (collapse + copy),
      `ToolCard` with **Everything/Truncated/Nothing** setting, dimmed
      `commentary` bubble.
- **Demo (on-device):** a multi-step prompt streams, shows reasoning above the
  answer, tool cards (toggle verbosity), and an intermediate beat.
- **Accept:** all four render correctly; tool verbosity setting changes
  rendering; reasoning copy button works; frame shapes match `04-wire-protocol`.

## M3 — Channels/threads + cron + search
**Goal:** organization + cron delegation + search.
- [ ] Channel directory (SQLite): default channel ensured; `channel.create/
      rename/set_default/delete` + `channel.*` frames.
- [ ] Threads: toggle in default chat; `thread_id` lanes; `create_handoff_thread`.
- [ ] `parse_target_ref_fn` + `cron_deliver_env_var` → cron
      `deliver=android:<chat>[:<thread>]` works.
- [ ] `search.py` FTS5 bridge; `search` frame (all / this-chat) → results.
- [ ] App: channel list (drawer/rail), thread toggle + topic switcher, "new
      channel" + "set as cron target", SearchScreen with scope toggle + jump.
- **Demo (on-device):** create "Cron Reports"; create a cron job delivering to
  it; it fires into that channel; search finds a message (both scopes).
- **Accept:** cron output lands in the chosen channel (not default); threads
  isolate context; search scoping correct; channel list reconciles on events.

## M4 — Media
**Goal:** attach + receive + play media.
- [ ] Inbound: `media.upload` chunked → `cache_*_from_bytes` → `media_urls`;
      size limit + sha256 + MIME re-sniff.
- [ ] Outbound: `send_*` → `media.offer`; `media.pull` chunked; delivery-path
      security.
- [ ] App: SAF pickers + preview chips + upload; `media.pull` → cache;
      **ExoPlayer** inline (audio mini-player, video fullscreen/PiP); image/doc
      viewers.
- **Demo (on-device):** attach a photo + video (agent sees them); ask agent to
  send an image/video → plays live in-app.
- **Accept:** both directions work; over-limit rejected; playback is live;
  only allowed files are servable.

## M5 — Push + offline (FCM + ntfy)
**Goal:** reach the phone when backgrounded; catch up on reconnect.
- [ ] Outbox (SQLite) + sync cursor; `sync`/`sync.done`; retention prune.
- [ ] `push.py`: `FcmBackend` (HTTP v1 + service account, httpx) +
      `NtfyBackend`; selected by `ANDROID_PUSH_BACKEND`.
- [ ] Fire push on no-live-subscriber; data payload for silent sync.
- [ ] App: FCM service (foreground banner + background foreground-service sync),
      `onNewToken` → `fcm.register`; per-chat notification channels; deep-link.
      ntfy listener fallback.
- [ ] In-app `notification` banners (channel_renamed, approval, cron, …).
- **Demo (on-device):** background the app → trigger a message → notification
  appears → tap → syncs + opens the chat. Repeat with ntfy backend.
- **Accept:** push arrives when backgrounded (both backends); reconnect syncs
  with no loss/dup; banners show for foreground events.

## M6 — Desktop app
**Goal:** the same app on a big screen.
- [ ] `desktopMain`: tray + OS notifications; `MediaPlayer` actual (mpv/WebView);
      `MediaPicker` actual (file dialog); `SecureStore` actual; window mgmt.
- [ ] Two-pane default layout; keyboard shortcuts; optional inspector pane.
- [ ] Parity pass vs Android feature checklist (`11-desktop-app.md`).
- [ ] jpackage builds (Linux first; macOS/Windows as available).
- **Demo:** desktop app pairs to the same gateway; full feature parity; tray
  notifications; media plays.
- **Accept:** all Android features work on desktop; tray + shortcuts work;
  native binary launches.

## M7 — Polish + E2E + docs
**Goal:** ship-quality.
- [ ] Telegram-style layout pass (per reference image): header, bubbles, date
      separators, ✓✓, model/token footer, banner, bottom bar.
- [ ] Theming (dark default, accent), onboarding/pairing UX, empty/loading/
      reconnecting/degraded states with honest copy.
- [ ] Full E2E suite (`13-testing.md` scenarios 1–12) automated where possible.
- [ ] Docs: `docs/protocol/frames.schema.json` finalized; `docs/setup.md`
      (user-facing pairing + FCM/ntfy + remote access); root README.
- [ ] Security hardening checklist (`09-pairing-security.md`) verified.
- **Demo:** end-to-end on phone + desktop simultaneously; cron into a channel;
  push; media; search.
- **Accept:** all feature-checklist items pass on-device; E2E green; docs
  complete; `hermes-agent/` still never committed.

## Sequencing notes
- **M1/M2 depend on the `ws_probe.py` harness** to lock frame shapes early —
  build it in M1.
- **M3 (cron) and M5 (push) both touch the outbox** — build the outbox in M3,
  extend for push in M5.
- **M6 (desktop) reuses M1–M5 shared code** — do it after the Android features
  are stable so the shared module is settled.
- Parallelizable: plugin (Python) and app (Kotlin) can be worked on
  concurrently once the protocol (`04-wire-protocol.md`) is agreed; the probe
  harness is the integration seam.
