fix(release): use Forgejo-style /assets and /tags API routes

The server (gitea.zephyre.one) exposes a Forgejo-compatible API:
- release attachments live at POST /releases/{id}/assets, not /attachments
- tag deletion is DELETE /tags/{tag}, not DELETE /git/refs/tags/{tag}
(verified against the live API: /attachments 404s, /assets and /tags exist)

 ## 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.
+- **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).
 - The plugin is installed by symlink: `~/.hermes/plugins/android` → `<repo>/gateway-plugin` (already set up on this machine).
 
 ## Layout
@@ -14,26 +15,26 @@
 ## Commands
 
 - `hermes` is **not on PATH**: use `hermes-agent/.venv/bin/hermes` (venv from `cd hermes-agent && uv sync`).
-- Gateway: `hermes gateway setup` (one-time; generates `ANDROID_TOKEN` in `~/.hermes/.env`, prints the token only once) → `hermes gateway` (run) → `hermes gateway status`.
+- Gateway: `hermes gateway setup` (one-time; generates `IRIS_TOKEN` in `~/.hermes/.env`, prints the token only once) → `hermes gateway` (run) → `hermes gateway status`.
 - Android: check the device is connected first (`adb devices` → `a5ca2a4b` listed as `device`); then `cd app && ./gradlew :androidApp:installDebug` to install on the phone and live-verify changes (launch/screenshot: see ADB below).
 - Desktop: `cd app && ./gradlew :desktopApp:run`; packaging: `:desktopApp:jpackage` (app-image; `-PjpackageType=deb` for a .deb).
 - Python tests — **never bare `pytest`**: `cd hermes-agent && scripts/run_tests.sh tests/gateway/test_android.py` (no args = full suite).
 - Kotlin tests: `cd app && ./gradlew :shared:testAndroidHostTest` / `:shared:desktopTest` (host-side; `jvmTest` is the shared source set).

 - E2E driver (gateway must be running; it never starts/stops it): `hermes-agent/.venv/bin/python gateway-plugin/tests/e2e.py`.
 
 ## Environment / pairing quirks
 
-- Pairing token: `ANDROID_TOKEN` in `~/.hermes/.env`. The app has **no QR scanner** — pairing is manual URL + token entry.
-- WS default bind is `127.0.0.1`; for a phone on the LAN set `ANDROID_WS_HOST` to the gateway's LAN IP.
+- Pairing token: `IRIS_TOKEN` in `~/.hermes/.env`. Pairing is manual URL + token entry; on **Android** there's also a QR-scan button (camera) that fills URL + token from the gateway's pairing QR. Desktop has no camera, so it's manual entry only.
+- WS default bind is `127.0.0.1`; for a phone on the LAN set `IRIS_WS_HOST` to the gateway's LAN IP.
 - `app/local.properties` (`sdk.dir`) is git-ignored and required for Android builds.
 - `google-services.json` is optional: without it FCM is inert and ntfy is the push path. Public ntfy.sh SSE is flaky — self-host ntfy.
-- JDK 17; no system Gradle — always the wrapper (`./gradlew`).
-- Desktop jpackage on Linux/JDK 17 prints a non-fatal `pure virtual method called` (JDK-8348560); the app works.
+- **JDK 21** is required (the desktop Markdown renderer ships Java-21 bytecode); no system Gradle — always the wrapper (`./gradlew`). The JDK-21 home is machine-specific and set per machine (NOT committed): add `org.gradle.java.home=/path/to/jdk21` to `~/.gradle/gradle.properties`, or `export JAVA_HOME=/path/to/jdk21` before running `./gradlew`.

 ## Testing quirks
 
-- `hermes-agent/tests/gateway/test_android.py` is a thin mirror that imports the **live `gateway-plugin/` package from this repo** (override with `ANDROID_PLUGIN_DIR`); HERMES_HOME is sandboxed per-test by the conftest. Tests must never touch the real `~/.hermes`.

 - e2e scenarios 3 (reasoning) and 5 (commentary) are model-dependent → SKIP; 11 (push) and 12 (reconnect) are PARTIAL by design.
 - 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.

+
+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).

-  drop to **outbox** + fire **push**.
+- A frame targets a `chat_id` whose device is **disconnected** (no live
+  SSE/long-poll subscriber) → drop to **outbox** + fire **push** — with one
+  refinement, *turn-aware push* (below).
 - Also fire push for high-priority foreground events the user should see even if
   the app is backgrounded (approvals, clarifies, cron completions) — the app
   decides whether to also show an in-app banner.
 - If the device is **connected**, no push (the live frame is enough).
 
+### 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).

+## M8 — QR pairing
+
+**Goal:** QR-based pairing — a scannable QR at `hermes gateway setup` plus an
+in-app scanner and `iris://pair` deep link (closes gap #12, `docs/20`).
+
+- [x] Pure-stdlib QR encoder + terminal renderer (`gateway-plugin/qr.py`):
+      byte mode, EC M with L fallback, versions 1–10, ISO penalty masking,
+      **zero new Python deps**.
+- [x] `interactive_setup` renders the QR after the pairing URL (text lines
+      stay as the primary path).
+- [x] `PairLink` parser (`iris/util/PairLink.kt`) + jvmTest (valid/missing
+      token/bad port/wrong scheme/wrong host/percent-encoded/secure/default
+      port).
+- [x] CameraX + ML Kit scanner (`QrScanActivity`, on-device, no Play
+      services) + Connect-screen **Scan QR** button (Android only; hidden on
+      desktop) + `CAMERA` permission.
+- [x] `iris://pair` deep link (system-scanner / other-phone fallback) reusing
+      the same parser.
+- **Accept:** `docs/20` §20.6; gap #12 in `09-pairing-security.md` closed.
+- **Status (2026-08-22):** Encoder cross-checked byte-for-byte against an
+  independent reference and decoded by an independent decoder (zbarimg); fixed
+  v1-M and v7-M matrix vectors lock the algorithm. `hermes gateway setup`
+  prints a scannable QR (v7-M, 45 modules) for the 64-hex-token payload. App:
+  Connect screen shows **Scan QR** (Android), which opens `QrScanActivity`
+  (CameraX camera2 + ML Kit barcode), requests `CAMERA`, and pre-fills URL +
+  token via `PairLink.parse` without auto-connecting; `iris://pair` deep link
+  pre-fills the same way. Docs updated per `docs/20` Part C.

+# 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.

+
+| # | 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) |
+| 3 | `PairLink` parser + jvmTest (B5) | `./gradlew :shared:testAndroidHostTest` |
+| 4 | Deps + manifest + `QrScanActivity` (B1/B2) | `:androidApp:assembleDebug` |
+| 5 | `PlatformQr` expect/actual + Connect button (B3/B4) | `:androidApp:assembleDebug` + `:desktopApp:run` (button absent, no crash) |
+| 6 | `iris://pair` deep link (B6) | ADB: `adb shell am start -a android.intent.action.VIEW -d "iris://pair?host=…&port=…&token=…"` → Connect screen pre-filled |

+
+**On-device E2E (final gate, per `13-testing.md` ADB workflow):**
+
+1. `hermes gateway setup` on the gateway host → QR in terminal.
+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 android 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`).

-        exact lane: a flat-lane delete (``thread_id=None``) matches only frames
-        with no ``thread_id``, and a thread delete matches only that thread's
-        frames (a ``message_id`` is unique to one lane, so this is a safety
-        net, not a filter that drops real frames). Returns the number of rows
+        exact lane first: a flat-lane delete (``thread_id=None``) matches only
+        frames with no ``thread_id``, and a thread delete matches only that
+        thread's frames. When the exact lane matches nothing, the delete falls
+        back to the ``message_id`` alone (it is a unique uuid4, so it cannot
+        hit the wrong message) — this keeps deletes working when the request's
+        lane is stale or missing (e.g. a message the app cached in the flat
+        lane that the gateway auto-threaded). Returns the number of rows
         removed (0 when the message is not in the outbox — e.g. already pruned
