gateway setup: offer self-signed TLS cert generation (no openssl needed)

hermes gateway setup now asks 'Set up TLS now?' when IRIS_HTTP_CERT is
not in .env (default No, Yes for an all-interfaces bind). Accepting
generates a 10-year RSA-2048 self-signed cert with SANs (advertised LAN
IP, hostname, loopback) under ~/.hermes/iris/ via hermes' existing
cryptography dependency, saves IRIS_HTTP_CERT/IRIS_HTTP_KEY, and prints
the SHA-256 fingerprint in openssl format for the app's confirm-and-pin
dialog. The pairing URL/QR printed afterwards already advertise https.

- key created 0600 from the start (no umask window)
- save_env_value inside the best-effort guard (unwritable .env warns)
- leftover cert without env var -> overwrite confirmation (protects the
  app's pinned fingerprint)
- bind wildcards (0.0.0.0 / ::) never become SANs; :: gets the same
  default-Yes as 0.0.0.0 (pairing._unroutable parity)

Tests: 5 new (cert generation incl. openssl fingerprint cross-check,
accept/decline, no re-prompt, default-follows-bind, overwrite prompt).

 ## Hard rules
 
 - `hermes-agent/` is a **read-only research reference** (git-ignored). Never commit, push, or modify it — a pre-commit hook (`scripts/guard_hermes_agent.sh --staged`) fails any commit that stages it. Never modify hermes core; we only install our plugin into the live hermes home.
-- The plugin is installed by symlink: `~/.hermes/plugins/android` → `<repo>/gateway-plugin` (already set up on this machine).
+- **Commit/push scope:** when asked to "commit and push all changes," that means **all** changes in the working tree — it does NOT matter whether a change was made this session or earlier. Stage everything (`git add .`) and commit; do not cherry-pick or second-guess which files are "yours." The only exception is `hermes-agent/` (git-ignored, never staged).

 - ADB: launch `adb shell am start -n dev.iris.app/.MainActivity`; reset pairing state `adb shell pm clear dev.iris.app`; screenshot `adb exec-out screencap -p > /tmp/shot.png`.
 - ADB UI taps: **never guess tap coordinates from a screenshot** — dump the hierarchy and tap the element's real bounds: `adb shell uiautomator dump` → `adb pull /sdcard/window_dump.xml` → find the node by `text` / `content-desc` / `resource-id` → `adb shell input tap` at the center of its `bounds="[x1,y1][x2,y2]"`. Re-dump after every navigation; if a tap misses, the dump is stale — re-dump, don't nudge coordinates.

+scrollable strip above the composer (max 3 lines; auto-scrolls to the item

+
+Both are **pure config** — raising the limit needs no code change in the plugin
+or hermes-agent. The app itself has no upload cap.
+
+**Why the caps exist:** the upload is streamed to a temp file (disk, bounded
+RAM in flight), but at completion the plugin reads the **entire blob into
+memory** (`UploadSession.read_bytes()` → `cache_*_from_bytes` →
+`write_bytes`), so peak RAM ≈ file size per upload. Hermes's cap exists to
+prevent OOM-killing the gateway (comment at `base.py:740-749`).
+
+**Inbound storage (gateway host):**
+
+- In flight: temp file `upl_*` under `~/.hermes/iris/media/tmp` (removed after
+  completion or failure).
+- After caching: hermes media cache — `~/.hermes/cache/images/img_<uuid12><ext>`,
+  `cache/audio/audio_<uuid12><ext>`, `cache/videos/video_<uuid12><ext>`,
+  `cache/documents/doc_<uuid12>_<original filename>`. Video/image/audio lose
+  their original filename; documents keep it.
+- Lifetime: hermes `cleanup_video_cache(max_age_hours=24)` deletes videos older
+  than 24 h.
+
+**Outbound (agent → app) — no size cap at the gateway.** `media.offer` carries
+metadata; `GET /v1/media/{id}` streams the full file in 256 KiB chunks
+regardless of size. The only constraints are the delivery-path re-validation at
+pull time and the 24 h offer TTL (`MediaStore.prune_outbound`).
+
+**The effective outbound limit is set by the app:** the device media cache is
+LRU-capped at 500 MB (§7.6) and `evict()` runs right after each pull completes.
+A single file > 500 MB makes the eviction loop delete everything — *including
+the file it just downloaded*. So files > ~500 MB arrive but are immediately
+discarded. To retain large agent→app files, raise `maxBytes` in
+`MediaCacheJvm.kt` (or exempt files from eviction).

+### 8.1.1 Turn-aware push (one push per turn, final answer as body)
+
+An agent turn can span minutes and emit several completed status messages
+("researching X…", "found Y…", "writing findings…", final answer). Pushing each
+parked message would spam an offline user with the steps in between. So while
+the agent's turn is **in flight** (hermes holds the typing indicator on from
+turn start until the handler's `finally` at turn end), normal-priority
+`message` / `message.stop` / `media.offer` frames that park with no live
+device are **held back** per chat instead of pushing; the latest one is pushed
+when the turn ends (`stop_typing`), so the offline user gets **one push with
+the final answer**. Details:
+
+- Turn state is tracked per `chat_id` from the typing indicator
+  (`send_typing` → in flight, `stop_typing` → ended; hermes fires
+  `stop_typing` in the handler's `finally`, after the final send, so the
+  flush always sees the final frame).
+- The held-back frame is still parked in the outbox — sync catch-up is
+  unaffected; only the push is deferred.
+- **High-priority notifications** (approval/clarify/cron) push immediately,
+  even mid-turn — they need user action.
+- If the device **reconnects mid-turn** (SSE/long-poll open), the held-back
+  push is dropped: the app syncs the parked frames and must not get a
+duplicate push at turn end.
+- If the turn ends while the device is live, nothing is pushed (the frames
+  were delivered live / synced).
+- Turns without a typing indicator (e.g. typing disabled in config) and
+  non-turn deliveries (cron, standalone sends) push immediately as before.
+- Best-effort: a gateway crash mid-turn loses the held-back push (the frames
+  remain in the outbox and sync on reconnect).

+    LAST option is *Exit* (leaves the removal loop, continues the setup);
+    picking a device asks for confirmation, then returns to the menu so
+    several devices can be removed in a row.
+  - **CLI** — `gateway-plugin/tools/iris_devices.py`:
+    - `list` — paired devices (id, name, token minted?, last seen) + revoked ids.
+    - `revoke <device_id>` — drops the device's row (token, push tokens,
+      cursor) AND adds its id to the `revoked` denylist: the device can no
+      longer connect with its device token **or** the shared token, while
+      every other device is unaffected. This is the isolation primitive a
+      shared token alone can't provide (a compromised device can't be cut
+      off without rotating the token for everyone).
+    - `unrevoke <device_id>` — removes it from the denylist so it can pair
+      again (a fresh token is minted at the next pairing).
+    - `reissue <device_id>` — rotates the device's token (the old one stops
+      working; the app picks up the new one on its next (re)connect via
+      `hello.ack`).
+  Re-pairing a revoked device also works by giving the app a fresh
+  `device_id` (e.g. `adb shell pm clear dev.iris.app`), which bootstraps
+  with the shared token like any new device.
+- **Allowlist (optional):** `IRIS_ALLOWED_USERS` (comma-separated

+# 20 — QR Pairing (terminal QR + in-app scanner)
+
+**Status: implemented (M8, 2026-08-22).**
+
+Closes gap #12 in `09-pairing-security.md` ("in-app QR scanner") and implements
+the QR branch of the §9.2 pairing flow, which the docs already promise but the
+code never delivered: today `interactive_setup` prints the pairing URL as
+plain text only, and the app has no `iris://pair` parser at all.
+
+Two halves, independent and shippable separately:
+
+- **A — Gateway:** `hermes gateway setup` renders a scannable QR in the
+  terminal encoding `iris://pair?host=…&port=…&token=…`. **Zero new Python
+  dependencies** (pure stdlib encoder).
+- **B — App:** a "Scan QR" button on the Android Connect screen (CameraX +
+  ML Kit, on-device, no Play services) that pre-fills URL + token. Not added
+  to desktop. Plus an `iris://pair` deep link so *any* scanner (system camera
+  app, other phones) can route the QR into the app.
+
+---
+
+## 20.1 Current state (what exists today)
+
+| Piece | State | Location |
+| ------- | ------- | ---------- |
+| QR payload format | ✅ implemented | `gateway-plugin/pairing.py` → `qr_payload(host, port, token, secure)` → `iris://pair?host=<lan-ip>&port=8791&secure=0&token=<64-hex>` |
+| Terminal QR rendering | ❌ missing | `gateway-plugin/adapter.py` → `interactive_setup()` prints the URL text only |
+| App `iris://pair` parser | ❌ missing | app has manual URL + token entry only (`ConnectScreen`) |
+| In-app camera scan | ❌ missing | no camera deps anywhere in `app/` |
+| `iris://` deep link | ⚠️ partial | manifest handles `iris://chat/<id>` only (`androidApp/.../AndroidManifest.xml`, `MainActivity.handleDeepLink`) |
+| QR libs in hermes venv | ❌ absent | `qrcode`/`segno` not installed; `Pillow` is a hermes core dep but only renders images — the QR *matrix* algorithm is still needed either way |
+
+Payload size: `iris://pair?host=192.168.x.x&port=8791&secure=0&token=<64 hex>`
+≈ **118 bytes** → QR version **7 at EC level M** (capacity 122 bytes) or v6 at
+L (134). The encoder must therefore support at least versions 1–8; we target
+1–10.
+
+---
+
+## 20.2 Part A — terminal QR in `interactive_setup`
+
+### A1. Pure-stdlib QR encoder — `gateway-plugin/qr.py` (new file)
+
+A self-contained ISO/IEC 18004 encoder, **stdlib only** (no `qrcode`, no
+`segno`, no Pillow). Scope is deliberately minimal — we only ever encode
+ASCII pairing URLs:
+
+- **Mode:** byte mode only (no alphanumeric/numeric/kanji paths).
+- **Error correction:** level **M** (15 %); auto-fallback to **L** if the
+  payload doesn't fit at M within the version cap.
+- **Versions:** 1–10, auto-selected (smallest version whose capacity fits).
+  Payloads that don't fit v10-L raise `QrTooLongError` (caller falls back to
+  text-only output — see A3).
+- **Components** (all well-known, spec-stable algorithms):
+  1. Data encoding: mode indicator `0100`, 8-bit char count (8 bits for
+     v1–9, 16 bits for v10), payload bytes, terminator, padding
+     (`0xEC`/`0x11` alternation).
+  2. Reed–Solomon error correction over GF(256), generator polynomial
+     `0x11D`, per (version, EC level) block structure from the spec tables.
+  3. Matrix placement: finder patterns + separators, timing patterns,
+     alignment patterns (v2+), dark module, format info (BCH(15,5)),
+     version info (v7+, BCH(18,6)), zig-zag data placement.
+  4. Masking: all 8 masks, ISO penalty scoring (N1–N4), pick lowest.
+- **Public API:**
+
+  ```python
+  def qr_matrix(data: str) -> list[list[bool]]:
+      """Encode *data* (ASCII) into a module matrix (True = dark).
+      Includes the 4-module quiet zone. Raises QrTooLongError."""
+  ```
+
+  ~250–350 lines including the spec tables. No I/O, no globals, fully
+  unit-testable.
+
+### A2. Terminal renderer — `qr.py`
+
+```python
+def render_qr(data: str) -> str:
+    """Render *data* as a terminal QR using Unicode half-blocks (▀).
+    Returns '' (not an exception) when the payload is too long."""
+```
+
+- Pair consecutive module rows into one character row: both dark → `█`,
+  top dark → `▀`, bottom dark → `▄`, both light → space. (Matrix height
+  including quiet zone is always even: `2·(17+4v)+8`.)
+- Output is a single string of `\n`-joined lines; the caller prints it.
+- No ANSI colors, no cursor tricks — must survive `less`, log files, and
+  copy-paste.
+
+### A3. Integration — `adapter.py:interactive_setup()`
+
+After the existing "Pairing URL / Server URL" lines:
+
+```python
+qr = render_qr(qr_payload(host, port, token))
+if qr:
+    print_info("Scan with the Iris app (Connect → Scan QR) or any camera app:")
+    print(qr)
+else:
+    print_warning("QR too large to render; use the pairing URL above.")
+```
+
+- The **URL text lines stay** — the QR is a convenience, not a replacement
+  (terminals without UTF-8 still work, and the text is copy-pasteable).
+- Printed on every setup run (new *and* existing token), consistent with the
+  URL lines which already print the token in cleartext.
+- **Security note:** no new exposure — the token is already printed in the
+  pairing URL line today; the QR is the same bytes in a different encoding,
+  on the same operator-only stdout. (Gap #5 in the §9.7 table already
+  documents the stdout token print.)
+
+### A4. Tests — `hermes-agent/tests/gateway/test_android.py`
+
+The test file is a thin mirror importing the **live `gateway-plugin/`
+package**, so new tests land there:
+
+1. **Fixed test vectors** (guard against silent algorithm drift): at least
+   two known-good (data → matrix) pairs from public QR test vectors
+   (e.g. the ISO 18004 annex examples / the classic `KARAT` v2-L vector).
+   Assert the full matrix, not just dimensions.
+2. **Round-trip via payload:** `qr_matrix(qr_payload(h, p, t))` has the
+   expected version/size for a 64-hex token (`17 + 4·7 = 45` modules at
+   v7-M, +8 quiet zone).
+3. **Renderer shape:** every line equal length, height = half of matrix
+   height, quiet zone renders as blank border, only the 4 block chars +
+   space appear.
+4. **`QrTooLongError` / `render_qr` → `""`** for a payload beyond v10-L.
+5. **`interactive_setup` smoke:** with sandboxed HERMES_HOME (conftest
+   already does this), capture stdout and assert the QR block appears after
+   the pairing URL line.
+
+Run: `cd hermes-agent && scripts/run_tests.sh tests/gateway/test_android.py`.
+

+
+## 20.3 Part B — in-app scanner (Android only)
+
+### B1. Dependencies — `app/shared/build.gradle.kts`, `androidMain.dependencies` only
+
+| Dependency | Why |
+| ------------ | ----- |
+| `androidx.camera:camera-camera2` | Camera access (CameraX) |
+| `androidx.camera:camera-lifecycle` | Lifecycle-aware binding |
+| `androidx.camera:camera-view` | `PreviewView` for the scan surface |
+| `com.google.mlkit:barcode-scanning` | On-device QR decode; **no Google Play services required** (self-contained model) |
+
+- Chosen over `zxing-android-embedded` (decided 2026-07-20): ML Kit has
+  better accuracy/latency, is maintained by Google, and works fully
+  on-device without GMS.
+- These go in **`androidMain`** only — the no-new-dep rule covers
+  `gateway-plugin/`, and the app already carries OkHttp/SQLDelight/KCEF/etc.
+  Desktop is untouched.
+- `minSdk 29` is fine for all four (ML Kit barcode needs 21+).
+- Versions go in the existing version catalog / `composeVersion`-style
+  constants at the top of the build file (follow the current pattern).
+
+### B2. Scanner activity — `shared/src/androidMain/kotlin/iris/platform/QrScanActivity.kt` (new)
+
+A minimal `ComponentActivity` (not a Fragment, no nav graph):
+
+- Layout: full-screen `PreviewView` + overlay hint text ("Point at the QR
+  code") + close button.
+- `ImageAnalysis` (STRATEGY_LATEST, YUV_420_888) →
+  `BarcodeScannerOptions(FORMAT_QR_CODE)` → first result →
+  `setResult(RESULT_OK, Intent().putExtra("iris.qr.text", raw))` → finish.
+- **Runtime permission:** request `CAMERA` on launch; on denial show a
+  message + close (the Connect screen still has manual entry).
+- Registered in `shared/src/androidMain/AndroidManifest.xml` (or the
+  androidApp manifest — follow where `NtfyListenerService` is declared)
+  with `android:exported="false"`, `android:theme` reusing the app theme.
+- Manifest additions (androidApp manifest):
+
+  ```xml
+  <uses-permission android:name="android.permission.CAMERA" />
+  <uses-feature android:name="android.hardware.camera" android:required="false" />
+  ```
+
+  `required="false"` so the app stays installable on camera-less devices
+  (the button then just reports "no camera").
+
+### B3. Platform hook — `expect`/`actual`
+
+`shared/src/commonMain/kotlin/iris/platform/PlatformQr.kt` (new):
+
+```kotlin
+/** Launch the QR scanner. [onResult] gets the decoded text, or null when
+ *  the user cancelled / no camera / permission denied. Desktop: no-op. */
+expect fun scanQrCode(onResult: (String?) -> Unit)
+```
+
+- **androidMain actual:** `ActivityResultLauncher` (from the Compose
+  `LocalContext`) starting `QrScanActivity`; maps `RESULT_OK` → text,
+  everything else → `null`.
+- **desktopMain actual:** `onResult(null)` immediately (the button is
+  hidden on desktop anyway — see B4; the no-op keeps the `expect` total).
+
+### B4. Connect screen button — `ConnectScreen.kt`
+
+- New **"Scan QR"** `Button` below the token field, rendered only when
+  `!isDesktop` (`iris.platform.isDesktop` already exists).
+- On tap: `scanQrCode { raw -> … }`; on non-null `raw`:
+  - `PairLink.parse(raw)` (B5) → pre-fill `url` and `token` state, clear
+    error, and **do not auto-connect** — the user still taps
+    "Test & Connect" (pairing stays an explicit act, per §10.8).
+  - Parse failure → set `error` to "Not a pairing QR code" (don't echo the
+    raw payload — it may contain someone else's token).
+- On `null` (cancel/denied): no-op, no error.
+
+### B5. Pair-link parser — `shared/src/commonMain/kotlin/iris/util/PairLink.kt` (new)
+
+```kotlin
+data class PairLink(val url: String, val token: String)
+
+object PairLink {
+    /** Parse `iris://pair?host=…&port=…&secure=…&token=…` → PairLink.
+     *  Returns null on any malformation. */
+    fun parse(raw: String): PairLink?
+}
+```
+
+- Accepts exactly scheme `iris`, host `pair` (case-insensitive scheme).
+- Required: `host` (non-empty), `token` (non-empty). `port` defaults to
+  `8791` (the HTTP default, `docs/19`); `secure` defaults to `0`.
+- Builds `url` as `http(s)://<host>:<port>`; validates port 1–65535.
+- URL-decodes `host`/`token` (the Python side `quote()`s them).
+- Pure function, no platform imports → **unit-tested in `jvmTest`**
+  (`:shared:testAndroidHostTest` / `:shared:desktopTest` both run it):
+  valid link, missing token, bad port, wrong scheme, wrong host,
+  percent-encoded host, secure=1 → https, default port.
+
+### B6. `iris://pair` deep link (system-scanner fallback)
+
+So a QR scanned by *any* app (phone's built-in scanner, a friend's phone)
+lands in Iris:
+
+- Manifest: extend the existing `VIEW` intent-filter block (or add a
+  sibling) with `<data android:scheme="iris" android:host="pair" />`.
+- `MainActivity.handleDeepLink`: on `iris://pair` → `PairLink.parse(uri)` →
+  stash into a `mutableStateOf<PairLink?>` passed into `IrisApp` →
+  `ConnectScreen` receives it as `prefillUrl`/`prefillToken` (the params
+  already exist). If the app is already connected, ignore (or surface in
+  Settings later — out of scope).
+- This reuses B5's parser; add one test for the URI shape Android delivers.

+## 20.4 Part C — doc updates (with the implementation)
+
+| Doc | Change |
+| ----- | -------- |
+| `09-pairing-security.md` | Gap #12 → **implemented** (fix the stale `adapter.py:648-654` reference while at it); §9.2 QR branch no longer aspirational |
+| `10-android-app.md` §10.8 | "or scan QR" becomes real: scanner button + deep link, camera permission |
+| `14-milestones.md` | New **M8 — QR pairing** section (acceptance criteria below) |
+| `16-open-questions.md` | Record decision: ML Kit over zxing; pure-stdlib encoder over vendoring `segno` |
+| `README.md` | Reading-order table: add row 20 |
+
+---
+
+## 20.5 Work breakdown & sequencing
+
+Ordered so each step is independently verifiable; A and B can be
+interleaved (different languages, no shared surface).
+
+| # | Task | Verify |
+| --- | ------ | -------- |
+| 1 | `qr.py` encoder + renderer (A1/A2) | new unit tests green (A4.1–4.4) |
+| 2 | `interactive_setup` integration (A3) | A4.5 + manual: `hermes gateway setup` in a real terminal shows a scannable QR (scan with the phone's *system* camera app as the decoder oracle) |

+2. Phone: `adb shell am start -n dev.iris.app/.MainActivity` → Connect →
+   **Scan QR** → grant camera → point at the terminal (screenshot the QR
+   onto a second screen if needed; the reference device is API 29 —
+   verify CameraX works on the MIX 2S in step 4 before building the rest).
+3. Fields pre-filled → **Test & Connect** → chat screen.
+4. Repeat via deep link (step 6 command) with a *different* token.
+5. Negative: scan a non-pairing QR (e.g. a website) → "Not a pairing QR
+   code", fields untouched.
+
+---
+
+## 20.6 Acceptance criteria (M8)
+
+- [ ] `hermes gateway setup` prints a QR that a stock Android camera app
+      decodes to exactly `qr_payload(host, port, token)`.
+- [ ] QR encoder: fixed test vectors + size/round-trip tests green;
+      **zero** new entries in the plugin's import surface (stdlib only —
+      verifiable by `ruff`/import scan).
+- [ ] Android: Connect screen shows **Scan QR** (hidden on desktop);
+      scanning the setup QR pre-fills URL + token; "Test & Connect" pairs.
+- [ ] Camera permission denied → graceful message, manual entry still works.
+- [ ] `iris://pair` deep link pre-fills the Connect screen (ADB-verified).
+- [ ] `PairLink.parse` unit tests cover the matrix in B5.
+- [ ] Full Python suite green: `scripts/run_tests.sh` (no args).
+- [ ] Docs updated per Part C; gap #12 closed.
+
+## 20.7 Risks & mitigations
+
+| Risk | Mitigation |
+| ------ | ------------ |
+| Hand-rolled QR encoder has a subtle bug | Fixed spec test vectors (A4.1) + the system-camera-app oracle in the E2E gate; scope locked to byte mode / v1–10 so the surface stays small |
+| Terminal without UTF-8 mangles the QR | URL text lines remain the primary path; QR is additive |
+| CameraX quirks on API 29 (MIX 2S) | Build the scanner activity first (task 4) and verify on-device before wiring the UI |
+| ML Kit model size (~4 MB) | Bundled in the APK, on-device, no runtime download — acceptable for this app's footprint |
+| Token in QR scanned by a bystander's phone | Same trust domain as the token already printed in the terminal; LAN pairing is operator-supervised by design (§9.2). Deep link only pre-fills — it never auto-connects |
+| `secure=1` (WSS) URLs | Parser already handles `secure` → `https://`; QR payload unchanged |
+
+## 20.8 Explicit non-goals
+
+- **QR display in the app** (showing a QR for other devices to scan) —
+  single-device pairing today; revisit if multi-device lands.
+- **`hermes iris pair` stretch CLI** (re-issue token + new QR,
+  `09-pairing-security.md` §9.2 line 48) — separate backlog item.
+- **WSS cert pinning** (gap #6) — orthogonal; QR carries `secure=1`
+  already, pinning is app-side.
+- **iOS scanner** — no iOS target (per `00-overview.md`).

+# Install — Gateway & App
+
+A step-by-step guide for getting **Iris** (the Android / Desktop app) talking
+to your **hermes gateway**. Written for people who just want to *use* it, not
+build it. If you only want the short version, the [README](../README.md) has
+the three commands that matter.
+
+The whole setup has two halves:
+
+1. **The gateway** — a small plugin that runs *inside* your existing hermes
+   install and opens a door for the app to connect through.
+2. **The app** — on your phone or desktop, where you enter the gateway's
+   address and a pairing token.
+
+> **Old guides?** Earlier versions of Iris used a WebSocket on port `8790`
+> (`ws://…/ws`). The transport is now plain HTTP on port **`8791`**
+> (see [`19-http-fallback-transport.md`](19-http-fallback-transport.md)).
+> The app still accepts old `ws://` URLs and converts them automatically, but
+> new setups should use the `http://` URL printed by `hermes gateway setup`.
+
+---
+
+## What you need
+
+| Where | What |
+| --- | --- |
+| Gateway host (any always-on computer: home server, Raspberry Pi, laptop) | [hermes-agent](https://github.com/NousResearch/hermes-agent) installed with its venv (`cd hermes-agent && uv sync`) |
+| Phone / desktop | Android 8+ or Linux / macOS / Windows |
+| Only if you build the app yourself | JDK 17 (+ Android SDK for Android) — see [`12-toolchain.md`](12-toolchain.md) |
+
+---
+
+## Part 1 — Install the gateway plugin (one-time)
+
+Iris is a regular hermes **platform plugin**, so it installs with the normal
+plugin command. This repo is a *monorepo* (the plugin lives in the
+`gateway-plugin/` subfolder, next to the app), so you point the installer at
+that subfolder with a `#subfolder` suffix:
+
+```bash
+hermes plugins install git@gitea.zephyre.one:ARIA/iris_x_hermes.git#gateway-plugin
+```
+
+That's it. The installer clones the repo, copies just the `gateway-plugin/`
+folder into `~/.hermes/plugins/`, and asks whether to enable it now (say
+**yes**).
+
+Notes:
+
+- Any git URL works with the `#gateway-plugin` suffix — e.g.
+  `https://gitea.zephyre.one/ARIA/iris_x_hermes.git#gateway-plugin` if you
+  prefer HTTPS.
+- **Developing from a checkout?** Skip the install and symlink instead — the
+  plugin then always tracks your working tree:
+
+  ```bash
+  mkdir -p ~/.hermes/plugins
+  ln -s "$PWD/gateway-plugin" ~/.hermes/plugins/iris
+  ```
+
+- Check it was picked up:
+
+  ```bash
+  hermes gateway status        # the Iris platform should be listed
+  ```
+
+## Part 2 — Gateway setup (one-time)
+
+Run the interactive setup:
+
+```bash
+hermes gateway setup
+```
+
+It walks you through five things:
+
+| Prompt | What it means | Default |
+| --- | --- | --- |
+| **Iris pairing token** | A long random secret the app must present to connect. Generated for you; stored in `~/.hermes/.env` as `IRIS_TOKEN`. **It is printed only once** — write it down. | auto-generated |
+| **HTTP host** | Which network address the gateway listens on. `127.0.0.1` = only this machine. For a phone on your home network, use the machine's **LAN IP** (e.g. `192.168.1.10`). | `127.0.0.1` |
+| **Port** | The port the app connects to. | `8791` |
+| **Push backend** | How offline notifications are delivered: `ntfy` (default, stays on your own infrastructure) or `fcm` (Google). See [Part 5](#part-5--push-notifications-optional). | `ntfy` |
+| **TLS** | Only asked when no certificate is configured yet: generates a **self-signed** certificate + key under `~/.hermes/iris/` and stores the paths in `.env` (`IRIS_HTTP_CERT` / `IRIS_HTTP_KEY`), so the gateway serves `https://`. The app asks you to confirm the printed SHA-256 fingerprint once (like an SSH host key). | No (Yes if you bound `0.0.0.0`) |
+
+When it finishes it prints two things you need for the app:
+
+- **Server URL** — e.g. `http://192.168.1.10:8791`
+- **Pairing QR + URL** — an `iris://pair?…` string with a scannable QR code
+
+Then start the gateway:
+
+```bash
+hermes gateway               # (or: hermes gateway restart after changes)
+```
+
+## Part 3 — Install the app
+
+### Android
+
+Build a debug APK on any machine with JDK 17 + the Android SDK:
+
+```bash
+cd app
+./gradlew :androidApp:assembleDebug
+# → app/androidApp/build/outputs/apk/debug/androidApp-debug.apk
+```
+
+Copy the APK to the phone (cable, LAN share, or any file transfer) and open
+it — Android will ask to allow installs from unknown sources.
+
+*Shortcut for developers with a USB-connected phone:*
+`./gradlew :androidApp:installDebug` installs it directly.
+
+### Desktop
+
+```bash
+cd app
+./gradlew :desktopApp:jpackage    # → app/desktopApp/build/…/ (native app, JRE bundled)
+```
+
+On Linux the launcher may print a `pure virtual method called` warning —
+it's a known, harmless jpackage bug (JDK-8348560); the app works fine.
+
+## Part 4 — Connect the app
+
+Open the app. The first screen is **Connect**. You need the **Server URL**
+and the **pairing token** from Part 2.
+
+### Option A — Same home network (no encryption, simplest)
+
+Works out of the box on a trusted home network:
+
+1. **Server URL:** the one printed by `hermes gateway setup`,
+   e.g. `http://192.168.1.10:8791`.
+   - On a phone, use the gateway's **LAN IP** — not `127.0.0.1` (that only
+     means "this device" and won't reach your server).
+   - If you set the host to `127.0.0.1` during setup, re-run
+     `hermes gateway setup` and enter the LAN IP instead.
+2. **Pairing token:** the long token from the setup output (or
+   `grep IRIS_TOKEN ~/.hermes/.env` on the gateway host).
+3. **Test & Connect.**
+
+> **Android shortcut:** the Connect screen has a **Scan QR** button — point
+> the camera at the QR printed by `hermes gateway setup` and the URL + token
+> fill themselves in. (Desktop has no camera, so it's manual entry.)
+
+### Option B — Encrypted (TLS) — recommended for anything beyond your LAN
+
+Plain `http://` is fine on a home network you trust, but for remote access
+you want the traffic encrypted. The gateway can serve `https://` itself:
+
+1. Create a certificate + key. Three flavors:
+   - **Generated by setup (easiest)**: `hermes gateway setup` offers to
+     generate a **self-signed** certificate for you (see the TLS prompt in
+     [Part 2](#part-2--gateway-setup-one-time)). It writes
+     `~/.hermes/iris/iris.crt` + `iris.key`, stores the paths in `.env`, and
+     prints the SHA-256 fingerprint the app will ask you to confirm.
+   - **CA-signed** (Let's Encrypt, or your own CA): works out of the box.
+   - **Self-signed manually** (e.g. `openssl req -x509 -newkey rsa:2048
+     -nodes -keyout iris.key -out iris.crt -days 3650 -subj "/CN=iris"
+     -addext "subjectAltName=DNS:iris.example.com,IP:192.168.1.10"`):
+     the certificate **must** carry a SAN entry matching the host you'll
+     type in the app.
+2. Put the paths in `~/.hermes/.env` on the gateway host:
+
+   ```ini
+   IRIS_HTTP_CERT=/path/to/iris.crt
+   IRIS_HTTP_KEY=/path/to/iris.key
+   ```
+
+3. `hermes gateway restart`.
+4. In the app, use the **`https://`** URL, e.g. `https://iris.example.com:8791`.
+
+**Self-signed certificates:** the app won't trust them automatically (by
+design). On first connect it shows the certificate's SHA-256 fingerprint and
+asks you to confirm it — exactly like an SSH host key. Compare the
+fingerprint with the one on the gateway host
+(`openssl x509 -fingerprint -sha256 -noout -in iris.crt`), confirm, and it's
+pinned in the app's secure storage from then on. If the certificate ever
+changes, you'll be asked to confirm again. No system trust-store installs
+needed.
+
+### Reaching the gateway from outside your home network
+
+Pick one (in order of preference):
+
+- **Tailscale / WireGuard (recommended).** Install Tailscale on the gateway
+  host; the app connects to the stable tailnet IP, e.g.
+  `http://100.x.y.z:8791`. No public exposure at all — and since the traffic
+  travels inside the encrypted mesh, plain `http://` is acceptable here.
+- **Reverse proxy / tunnel** (Caddy, Cloudflare Tunnel, ngrok). Terminate TLS
+  at the edge and forward to `127.0.0.1:8791` on the gateway host.
+- **Public bind + TLS + strong token** (`IRIS_HTTP_HOST=0.0.0.0` + Option B).
+  Last resort — the port is then reachable from the internet; the token and
+  TLS are what protect it.
+
+## Part 5 — Push notifications (optional)
+
+Push wakes a backgrounded or offline phone so you see replies even when the
+app is closed. Nothing is lost either way — on reconnect the app syncs its
+outbox.
+
+- **ntfy (default)** — the phone generates its own topic automatically; the
+  gateway publishes to it. Set `NTFY_SERVER_URL` to a **self-hosted ntfy**
+  for reliability (the public `ntfy.sh` SSE endpoint is flaky). Push metadata
+  stays on your own infrastructure — this is the private option.
+- **FCM (opt-in, `IRIS_PUSH_BACKEND=fcm`)** — standard and reliable, but push
+  metadata (notification title, device token) is routed through **Google's
+  servers**. Needs a Firebase project + `google-services.json` in the app
+  build. Without it, FCM is inert and ntfy is the path.
+
+Details: [`08-push.md`](08-push.md).
+
+---
+
+## Gateway options (reference)
+
+Everything is configured in `~/.hermes/.env` on the gateway host (or via the
+prompts of `hermes gateway setup`). After changes: `hermes gateway restart`.
+
+| Variable | What it does | Default |
+| --- | --- | --- |
+| `IRIS_TOKEN` | Pairing token the app must present. | — (required) |
+| `IRIS_HTTP_HOST` | Bind address. `127.0.0.1` = local only; LAN IP = same network; `0.0.0.0` = all interfaces. | `127.0.0.1` |
+| `IRIS_HTTP_PORT` | Port the app connects to. | `8791` |
+| `IRIS_HOME_CHANNEL` | Default chat for cron/notification delivery. | `default` |
+| `IRIS_ALLOWED_USERS` | Comma-separated device ids allowed to connect (empty = token-only auth). | empty |
+| `IRIS_ALLOW_ALL_USERS` | Allow any paired device (**dev only**). | `false` |
+| `IRIS_PUSH_BACKEND` | `ntfy` or `fcm`. | `ntfy` |
+| `IRIS_FCM_SERVICE_ACCOUNT` | Path to Firebase service-account JSON (FCM). | — |
+| `IRIS_FCM_SERVER_KEY` | Legacy FCM server key (fallback). | — |
+| `NTFY_SERVER_URL` | ntfy server. Self-hosting recommended. | `https://ntfy.sh` |
+| `NTFY_AUTH_TOKEN` | Auth token for a private ntfy topic (real trust boundary). | — |
+| `IRIS_HTTP_CERT` / `IRIS_HTTP_KEY` | TLS cert/key paths → serves `https://` (see Part 4, Option B). | — |
+
+Security model (tokens, device allowlist, transport):
+[`09-pairing-security.md`](09-pairing-security.md).
+
+---
+
+## Troubleshooting
+
+| Symptom | Likely cause / fix |
+| --- | --- |
+| `auth failed` on connect | Wrong token. Check `IRIS_TOKEN` in `~/.hermes/.env` (setup prints it only when it generates it). |
+| Connection refused | Gateway not running (`hermes gateway status`); wrong URL (port `8791`, LAN IP instead of `127.0.0.1` from a phone); firewall blocking the port. |
+| Phone can't reach the gateway | Gateway bound to `127.0.0.1` — re-run `hermes gateway setup` and set the LAN IP; or the phone is on a different network/VLAN. |
+| TLS handshake fails | Cert has no SAN matching the URL host; or the pinned fingerprint is stale after a cert change (re-confirm in the app). |
+| Push not arriving | Backend not configured (check `~/.hermes/logs/gateway.log`); ntfy.sh flakiness — self-host ntfy. |
+| Start over on a phone | `adb shell pm clear dev.iris.app` wipes the app's pairing state. |
+
+Logs: `~/.hermes/logs/gateway.log` or `hermes logs --follow`.

+  **Google's servers**. If you want truly private communication, use ntfy

+
+## Privacy note (for the "Data safety" section / FAQ)
+
+Iris talks directly to your own hermes gateway over a private, token-authenticated
+connection. By default, push notifications use ntfy, which you can self-host so
+that push metadata never leaves your infrastructure. If you explicitly enable
+FCM, push metadata (notification title, device token) is sent via Google's FCM
+servers; chat content itself is not sent to Google — FCM only carries a short
+preview, and full content is fetched from your gateway over the authenticated
+connection. For truly private communication, use the default ntfy backend
+(self-hosted).

+> and connecting (LAN / TLS / remote). This file is kept so old links keep
-[`08-push.md`](08-push.md), [`12-toolchain.md`](12-toolchain.md)); this page is
+> working.
-just the steps.
+>
-
+> - Push details: [`08-push.md`](08-push.md)
-## Prerequisites
+> - Security model: [`09-pairing-security.md`](09-pairing-security.md)
-
+> - Toolchain (first-time machine setup): [`12-toolchain.md`](12-toolchain.md)
-| Where | You need |
-|---|---|
-| Gateway host | hermes installed with its venv (`cd hermes-agent && uv sync`, see [`12-toolchain.md` §12.4](12-toolchain.md)) |
-| Android build machine | JDK 17, Android SDK with `ANDROID_HOME` set (or `app/local.properties`), ADB with a connected device |
-| Desktop build machine | JDK 17 only |
-
-Gradle needs no system install — both apps use the project wrapper
-(`./gradlew`). First-time machine setup: [`12-toolchain.md`](12-toolchain.md).
-
-## 1. Gateway setup (on the gateway host)
-
-Install the plugin into the live hermes home (dev: a symlink from the monorepo
-root):
-
-```bash
-mkdir -p ~/.hermes/plugins
-ln -s "$PWD/gateway-plugin" ~/.hermes/plugins/android
-hermes gateway status        # should list "android"
-```
-
-Run the interactive setup:
-
-```bash
-hermes gateway setup
-```
-
-What it does:
-
-- Generates `ANDROID_TOKEN` (64 hex chars) if none exists and stores it in
-  `~/.hermes/.env` (it prints the token once, at generation).
-- Prompts for the WS bind host (default `127.0.0.1`), port (default `8790`),
-  and push backend (`fcm` or `ntfy`, default `fcm`).
-- Prints the pairing payload (a QR-encodable `iris://pair?host=…&port=…&token=…`
-  string) and the server URL (`ws://<host>:8790/ws`).
-
-Then start the gateway:
-
-```bash
-hermes gateway               # or: hermes gateway restart after config changes
-```
-
-> **Note:** the default bind host `127.0.0.1` only accepts connections from the
-> gateway host itself (e.g. a desktop app on the same machine). For a phone on
-> the LAN, re-run `hermes gateway setup` (or edit `~/.hermes/.env`) and set
-> `ANDROID_WS_HOST` to the host's LAN IP (e.g. `192.168.1.10`).
-
-## 2. Android app
-
-Build and install (ADB device connected):
-
-```bash
-cd app
-./gradlew :androidApp:installDebug
-```
-
-First run opens the **Connect** screen:
-
-1. **Server URL** — `ws://<gateway-ip>:8790/ws` (the URL printed by
-   `hermes gateway setup`; use the LAN IP, not `127.0.0.1`, from a phone).
-2. **Pairing token** — from the `hermes gateway setup` output, or
-   `grep ANDROID_TOKEN ~/.hermes/.env` on the gateway host.
-3. **Test & Connect** — performs a real `hello` (the auth leg), then saves the
-   pairing and connects.
-
-> **Honest limitation:** QR scanning is **not** supported in the app yet. The
-> server prints a QR payload, but pairing is manual URL + token entry only.
-
-## 3. Desktop app
-
-```bash
-cd app
-./gradlew :desktopApp:run        # dev run
-./gradlew :desktopApp:jpackage   # native app-image (bundles the JRE)
-```
-
-Pairing is the same Connect screen (URL + token); the token is stored in the OS
-keyring (with an encrypted-file fallback). Desktop push is tray icon + OS
-notifications (no FCM).
-
-> **Known issue:** on Linux with JDK 17 the jpackage launcher prints a
-> non-fatal `pure virtual method called` warning (JDK-8348560, a
-> jpackage/Linux launcher bug). The app runs and connects regardless.
-
-## 4. Push notifications
-
-Push wakes a backgrounded/offline device; on reconnect the app syncs the
-outbox, so nothing is lost. Push fires when the device is offline, plus for
-high-priority events (approvals, clarifies, cron) even when a device is live.
-
-### FCM (default; needs a Firebase project)
-
-1. Create a Firebase project (console.firebase.google.com) and add an Android
-   app with the app's applicationId; download `google-services.json` into
-   `app/androidApp/`.
-2. Create a service account (Project settings → Service accounts → Generate new
-   private key) and store the JSON path in `~/.hermes/.env`:
-   `ANDROID_FCM_SERVICE_ACCOUNT=/path/to/service-account.json`.
-3. Keep `ANDROID_PUSH_BACKEND=fcm` (the default).
-
-Without a Firebase project the FCM path is **inert** (the app's FCM service
-does nothing) — use ntfy below, or add Firebase later.
-
-**What you see:** system notifications for new messages when the app is
-backgrounded; tapping one deep-links to the chat.
-
-### ntfy (zero-config fallback)
-
-```
-ANDROID_PUSH_BACKEND=ntfy
-```
-
-- The device **generates its own topic** automatically (no `NTFY_TOPIC` needed);
-  the server publishes to it.
-- `NTFY_SERVER_URL` defaults to `https://ntfy.sh`. **Self-hosted ntfy is
-  recommended** — the public ntfy.sh SSE endpoint is flaky (it has served its
-  web UI instead of the stream), while a self-hosted instance gives reliable
-  SSE. For a real trust boundary use a private topic + `NTFY_AUTH_TOKEN`.
-
-**What you see:** a low-priority foreground "ntfy listener" notification while
-the app is off; incoming pushes trigger a silent sync.
-
-## 5. Remote access
-
-- **Tailscale / WireGuard (recommended):** the gateway gets a stable tailnet IP;
-  the app connects to `ws://<tailnet-ip>:8790/ws`. No public exposure.
-- **Reverse proxy / tunnel** (Caddy, Cloudflare Tunnel, ngrok): terminate TLS at
-  the edge, forward the WebSocket to `127.0.0.1:8790`.
-- **WSS:** set `ANDROID_WS_CERT` / `ANDROID_WS_KEY` (paths, in
-  `~/.hermes/.env`) and the server serves `wss://` instead of `ws://`.
-
-> **Honest limitation:** the app has **no certificate pinning** yet, so
-> self-signed certs won't work — remote access requires **CA-signed** WSS for
-> now. Plain `ws://` on a trusted LAN (or inside Tailscale) stays the default.
-
-## 6. Troubleshooting
-
-| Symptom | Likely cause / fix |
-|---|---|
-| `auth failed` / `error {code:"auth"}` on connect | Wrong token. Check `ANDROID_TOKEN` in `~/.hermes/.env` on the gateway host (setup prints it only when it generates it). |
-| Connection refused | Gateway not running (`hermes gateway status`); wrong URL (port `8790`, path `/ws`, LAN IP instead of `127.0.0.1` from a phone); firewall blocking the port. |
-| Push not arriving | Backend not configured (gateway log: `push backend … not configured`); app backgrounded with no working backend; ntfy.sh SSE flakiness — use a self-hosted ntfy. |
-| Desktop jpackage launcher warning | Non-fatal (JDK-8348560 on Linux JDK 17); the app runs and connects regardless. |
-
-Smoke test without the app (from the gateway host):
-
-```bash
-python - <<'PY'
-import asyncio, json, websockets
-async def main():
-    async with websockets.connect("ws://127.0.0.1:8790/ws") as ws:
-        await ws.send(json.dumps({"v":1,"type":"hello","payload":{
-            "token":"<ANDROID_TOKEN>","device_id":"test","device_name":"probe",
-            "caps":{"min_protocol":1}}}))
-        print("recv:", await ws.recv())
-asyncio.run(main())
-PY
-```
-
-Expect a `hello.ack`. If you get `error {code:"auth"}`, the token/host/port is
-wrong.
