# Hermes Mobile — Delivery Plan

> **Operational contract:** Codex must read this file before each work loop. Work exactly one coherent milestone at a time. Move completed items to the completed section in the same commit that implements them. Add a concise entry to `CHANGELOG.md` in the same commit. Never mark work complete without running its listed verification.

## Product guardrails

- Native Android client for upstream Hermes Agent: **Kotlin + Jetpack Compose**.
- Material 3 base, deliberately customized through a reusable design system.
- Thin client: Hermes remains the authority for auth, sessions, streaming, tool semantics, and backend behavior.
- No WebView-first app, no cloned Hermes backend, no embedded credentials.
- Adaptive, accessible, compact-but-readable UI: phone, tablet, light/dark, font scaling, IME/keyboard, long code/output must remain safe.
- Keep DTO/transport, domain/UI models, repositories, view models/state, and composables separated.
- Never commit APKs, build outputs, credentials, or generated local environment files.

## Release policy

- Start artifacts at `v0.1.0-beta.1`.
- Patch: compatible fixes/polish. Minor: a coherent feature milestone. Major: stable `v1.0.0+` only.
- A release requires a pushed source commit, passing relevant checks, a versioned APK artifact, and a Telegram release post.

## Now — finish the foundation already in progress

_Foundation milestones complete. Continue with B1._

## Beta path — upstream-connected MVP

- [ ] **B1 — Transport/domain contracts**
  - Define transport DTOs and a repository interface for server profiles, authentication, sessions, messages, stream events, tool results, and artifacts.
  - Map DTOs to stable UI models; fake repository powers previews/tests.
  - Keep the existing companion as an optional adapter only; do not change upstream Hermes semantics.
  - Verification: unit tests for mapping/state reducers; build/typecheck.

- [ ] **B2 — Connection and authentication UX**
  - Server connection screen with validation, health, auth/session configuration, offline/unauthorized/retry states.
  - Store sensitive values using Android-appropriate secure storage; never log secrets.
  - Verification: connection-state tests and manual unhappy-path walkthrough.

- [ ] **B3 — Session list and durable chat state**
  - Fetch/list/search/select/create sessions through repository contracts.
  - Restore selected session and protect against duplicate sends / lost drafts.
  - Verification: fake-repository UI tests; companion/integration checks where available.

- [ ] **B4 — Streaming, reconnects, and resilient long-running work**
  - Stream event reducer: token deltas, tool lifecycle, final/error/cancel, reconnect/backoff.
  - Preserve partial output and make recovery obvious and safe.
  - Verification: deterministic fake stream tests and real upstream-compatible exercise.

- [ ] **B5 — Tool, artifact, and output experience**
  - Compact tool cards with lifecycle/status, expandable output, copy/share/save affordances.
  - Safe rendering for large logs and code; no unbounded nested scroll failures.
  - Artifact/file handoff only where upstream capability is actually supported.
  - Verification: large-output and rotation/resume checks.

## Beta hardening and release

- [ ] **R1 — Adaptive/accessibility quality pass**
  - Small phone, normal phone, tablet/two-pane behavior; portrait/landscape.
  - Font scaling, TalkBack semantics, contrast, touch targets, reduced motion, IME behavior.
  - Verification: emulator/device matrix evidence documented in `docs/ROADMAP.md`.

- [ ] **R2 — Beta packaging and install guide**
  - Version `v0.1.0-beta.1`, reproducible debug/beta APK build, install/run guide, known limitations.
  - Publish source commit, APK, release notes, and verification result.
  - Verification: clean install on a real device or emulator plus full required checks.

## V2 backlog

- [ ] Multiple server profiles and fast switching.
- [ ] Rich file/artifact workflows based on upstream capability.
- [ ] Notifications for task completion.
- [ ] Mature tablet/two-pane session + optional terminal/log pane.
- [ ] Offline cache/search and diagnostic export with privacy controls.

## Completed

_Move finished items here with date, commit, and verification. Keep this section factual; do not claim unverified work._

- [x] **F0 — Audit and safely land existing work** — 2026-07-24, commit `da79d48` (`feat: land native mobile foundation`).
  - Reviewed existing Android and companion edits; preserved the native Android chat/workspace/settings work and companion chat hardening.
  - Confirmed generated build outputs are ignored and added ignores for `.gradle-user/` and `.dev/`.
  - Reconciled `docs/ROADMAP.md` to the actual native Android beta state and remaining validation gaps.
  - Verification: `git diff --check` passed; `npm run typecheck --workspace @hermes-mobile/companion` passed; `npm run lint --workspace @hermes-mobile/companion` passed; `npm run build --workspace @hermes-mobile/companion` passed; `npm run typecheck` passed; `npm run lint` passed; `npm run build` passed.
  - Android debug build attempted with `GRADLE_USER_HOME=/root/hermes-mobile/.gradle-user ./gradlew :app:assembleDebug` from `apps/mobile/android`; blocked before compilation because network socket creation is not permitted while downloading Gradle 8.11.1.

- [x] **F1 — Compose design system extraction** — 2026-07-24, commit `9ed0969` (`feat: extract compose design system`).
  - Extracted color, semantic status, spacing, typography, shape, elevation, and motion tokens.
  - Added light and dark Hermes Compose themes backed by Material 3 color schemes.
  - Split shared Compose cards, rows, controls, notices, message bubbles, list scaffolds, and code surfaces out of `MainActivity.kt`.
  - Added Compose previews for small phone, normal phone, tablet width, light theme, and dark theme component coverage.
  - Verification: `git diff --check` passed; `GRADLE_USER_HOME=/root/hermes-mobile/.gradle-user ./gradlew :app:assembleDebug` from `apps/mobile/android` passed.

- [x] **F2 — Polished fake-data chat proving ground** — 2026-07-24, commit `f65d4ac` (`feat: add fake chat proving ground`).
  - Added a local fake chat inbox with session rail/list, context controls, keyboard-safe composer, and send/cancel/retry interactions.
  - Added typed user, assistant, system, error, and streaming message models; selectable markdown-friendly text, horizontally scrollable copyable code, and expandable tool results.
  - Added seeded empty, loading, reconnecting, and error states plus reducer tests for send, cancel, retry, and tool expansion.
  - Verification: `git diff --check` passed; `GRADLE_USER_HOME=/root/hermes-mobile/.gradle-user ./gradlew :app:testDebugUnitTest :app:assembleDebug` from `apps/mobile/android` passed.

## Work-loop checklist

Before coding:
1. Read `PROJECT_PLAN.md`, `CHANGELOG.md`, `docs/ROADMAP.md`, git status, and the prior commit.
2. Choose the single highest-value unchecked item or a narrowly scoped sub-item.
3. Inspect existing implementation before rewriting it.

Before committing:
1. Run relevant checks; record exact pass/fail scope in the changelog.
2. Update this plan: check the completed item, move it into **Completed**, and leave the next executable item unchecked.
3. Add a concise `CHANGELOG.md` entry under **Unreleased**.
4. Commit using Conventional Commits and push `origin/main`.
5. Do not claim a release without an uploaded, verified versioned APK.
