-/**
- * The Receiving section: what this phone will take, and from which device.
- *
- * The interesting thing here is SCOPE. The user picks All devices or one device and then edits rules for that
- * scope, and the same switch has to route to a different handler depending on which is selected - a device rule
- * overrides the global one. Getting that wrong is silent and expensive: the user turns off screenshots from one
- * laptop and it stops accepting them from everything, or they think they have restricted one device and have
- * restricted nothing.
- *
- * So these tests press real buttons on the real component and assert WHICH callback fires with which arguments,
- * because that is the only externally visible difference between the two cases.
- *
- * The projection that resolves device-versus-global precedence is real (@offgrid/sync), so the rows and the
- * enabled answers are computed the way the app computes them. Only the icon font is shimmed.

+# Cross-device sync feedback — 2026-08-12
+
+## The rule this list is fixed under
+
+Mac stated it while we worked through these, and it is the generative diagnosis of nearly every item
+below, so it goes first.
+
+**All business logic lives in `shared/sync`. Desktop and mobile are consumers.** Not "mostly", and not
+"the tricky parts". A host supplies FACTS about its platform - what addresses it holds, what the user
+tapped, what is on disk - and consumes decisions. It decides nothing.
+
+**Everything that moves is an ITEM on one durable queue, and the queue syncs it.** A clipboard entry, a
+chat, a model, an attachment, a generated image: one item kind each, one queue, one set of rules for
+retry, ordering, receive gates and provenance. Durability is the point - a device that is offline means
+"not yet", never "lost". Mac: _the durability of the queue is very important._
+
+**"X works here and Y does not" is the tell.** Every time this list says one direction works and the
+other does not, or one file kind arrives and another does not, the cause is the same shape: two code
+paths doing one job, one per host or one per kind, and only one of them was got right. That is not fixed
+by patching the broken side. It is fixed by deleting the second path.
+
+Today's evidence, all of it this shape:
+
+- A file's activity found its bytes on desktop and not on mobile, because each host answered "which peer
+  is this activity keyed by" from what it happened to hold.
+- A cancelled pairing attempt cleared on desktop and stuck on mobile, because each screen listed the
+  stages it would show.
+- The desktop published no mDNS record, because it read its own address once while mobile had a rule for
+  following it.
+- Attachments travel desktop to android and generated media does not, which is two paths for one job.
+
+So the fix for each entry below is the same question first: **where is the one owner, and is it in
+`shared/sync`?** A change that leaves the rule in a host is not a fix; it is the next report.
+
+Two sources, and they are not about the same build. Keeping them apart decides what has an installed base.
+
+- **Anurag** tested the CURRENT build - 0.0.104-beta.1 mobile against desktop on macOS and Windows -
+  reported in Slack between 09:31 and 10:07. Cross-device sync ships for the first time here, so nothing
+  in his section has users in the field behind it.
+- **Pat and the Muse Glimmer report** are about PREVIOUSLY SHIPPED releases. The app has an installed base
+  even though sync does not, so a licence seat, a model that will not load, and a modality switch are all
+  live for real users right now - and they cannot be fixed by "there is nothing to migrate".
+
+Recorded as each person described it. Nothing here is diagnosed unless the cause is established; a guess in
+this list would be read as a finding.
+
+## Defects
+
+- **Pairing keeps a dead attempt alive.** Enter a wrong code, cancel, and the state does not reset. The
+  next attempt still shows "pairing…", and only restarting the app clears it. Mobile.
+
+  **STILL OPEN.** A first fix hid a cancelled attempt from the sheet;
+  `deviceManagement.integration.test.tsx` disproved the premise by passing without it - that journey
+  cancels, reads "Pairing cancelled", retries and pairs. So retry-after-cancel already works from
+  `waiting_for_confirmation`, and the confirmation is a message the design wants. Reverted.
+
+  Kept from that work: an attempt is read at its LAST state, so it can never be presented from an earlier
+  row of its own history - which was a second route to the same stuck sheet.
+
+  The untested difference is the order. The passing journey cancels while still waiting; Anurag cancelled
+  an attempt that had already FAILED on a wrong code, and a terminal attempt may have nothing left to
+  cancel. Needs the three-step sequence walked on a device before anything else is changed.
+
+- **A file sent phone → Windows arrives with no local file.** The transfer reports complete, then the
+  activity row reads "This activity no longer has a local file" and the file will not open. Windows
+  desktop, receive path. Confirmed by Anurag at 09:52 as a MANUAL send, not an ambient share - so the
+  explicit share path is what to read, and the ambient rules are not in it.
+- **Clipboard Android → desktop never arrives.** iPhone → desktop works. Cause found on 2026-08-12: from
+  Android 10 the platform refuses `primaryClip` to an app that is not on screen, so the copy reaches the
+  app with no text behind it and is dropped. Fix in progress on `feat/android-clipboard-accessibility`.
+- **A reply to a phone-sent message is slow on desktop, and sometimes leaks the system prompt.** The
+  response occasionally opens with "A helpful AI assistant running locally on your device." — which is
+  the persona text, not an answer — despite the model running on device.
+
+  **Traced as far as the evidence allows, and NOT fixed.** That sentence exists only in mobile, so it
+  reached the desktop over sync, and `systemPrompt` is a synced model setting - the route is real. But the
+  evidence has since been overwritten: the synced `systemPrompt` on that Mac now reads
+  `"follow instructions"`, and no `messages` row contains the persona text. Nothing left to diagnose from.
+
+  What was fixed is what made it unattributable: mobile held THREE default personas
+  (`constants/index.ts`, `appStore.ts`, `projectStore.ts`), all opening with that sentence, so there was no
+  single source to point at. They now share one owner.
+
+  To catch it next time, before changing any setting:
+
+  ```sh
+  sqlite3 "$HOME/Library/Application Support/Off Grid AI Desktop/memories.db" \
+    "SELECT key, origin_device_name, value_json FROM sync_model_settings WHERE key='systemPrompt';
+     SELECT id, role, substr(content,1,120) FROM messages
+     WHERE content LIKE '%helpful AI assistant running locally%';"
+  ```
+
+- **The web-search result reads as the answer.** Anurag was confused about which part was the response.
+  Not reproduced: the tool result already renders as a collapsed 32-character chip in `MemoryChat.tsx`, not
+  expanded, so what he saw was something else in the answer bubble - plausibly the same class as the
+  persona leak above, which is content arriving where the reply belongs. Needs a screenshot of the turn.
+
+- **Windows image generation breaks its own preview.** The image is generated but the preview cannot
+  resolve its path; downloading the file works. This also blocks any test of image-generation sync. Anurag
+  believes the preview has always been broken here, so it may predate this release.
+
+  **FIXED.** The handler sliced the scheme off the URL string, but a URL's authority comes before its path -
+  so `ogcapture://C:/Users/oga/…` put the drive letter in the HOST and dropped its colon, leaving
+  `C/Users/oga/…`, which names nothing. macOS never showed it because its paths start with a slash. Now
+  parsed by `capturePathFromUrl`, pure and tested on both dialects.
+
+- **An image attached on the phone will not open on desktop.** It reports that the file has moved.
+- **Generated media does not travel desktop → android.** Attachments from the same direction do arrive, so
+  the transport is working and the generated-media path specifically is not.
+- **The desktop publishes no mDNS record when a dead interface is present.** Found on 2026-08-12 while
+  chasing "the Android debug build cannot find OGAD". `new Bonjour({}, onError)` in
+  `desktop/pro/main/sync/desktop-discovery.ts` binds every interface, so an `en7` with link but no DHCP
+  lease (self-assigned `169.254.112.10`) makes the multicast send fail:
+
+  ```
+  [sync] Bonjour discovery unavailable: send EHOSTUNREACH 224.0.0.251:5353
+  ```
+
+  `sync.discoverable` reads true while the wire carries nothing. A phone that is ALREADY paired keeps
+  working, because it dials the saved address - which is why only a fresh install shows it. The address
+  the socket should use is the one `lanAddress()` already picks, and its predicate already rejects
+  link-local and virtual interfaces.
+
+- **A desktop profile that predates the default keeps the old one.** A fresh Android install already has
+  generated media and message attachments on, with an offline device set to queue. Anurag's DESKTOP needed
+  both switched on by hand.
+
+  **Not a code divergence, and NOT an old default either.** Both hosts read the same
+  `DEFAULT_RECEIVE_POLICY` from `shared/packages/sync/src/receive-policy.ts`, and its history shows
+  `disabledCategories: []` from the first commit onward - there has never been a default that disabled a
+  category. So a stored policy with categories off did not come from a default; it came from a choice made
+  on that machine, by hand or by an earlier test run.
+
+  **Closed: nothing to migrate.** Sync ships for the first time in this release, so there are no stored
+  receive policies in the field to protect - the objection to a migration was about overriding real user choices, and there are none. The
+  only thing that has to be right is what a FRESH install gets, and that is proven: `DEFAULT_RECEIVE_POLICY`
+  is `enabled: true` with nothing disabled, and the two categories added today for generated media and
+  message attachments inherit it. `receive-category-coverage.test.mjs` asserts both are accepted from a
+  paired device by default.
+
+  Anurag's Mac is a development profile whose categories were switched off during earlier testing, which is
+  a fact about that machine and not about the product.
+
+  Unprovable now in any case: switching them on overwrote the value, which today reads
+  `{"enabled":true,"disabledCategories":[],"devices":{}}`.
+
+  If a fresh profile ever comes up with categories disabled, that IS a real defect - and the place to look
+  is whichever host wrote the first policy, not the shared constant.
+
+## Not defects
+
+- **An attachment from desktop not showing on the phone** — the receive category was switched off. User
+  error, confirmed by Anurag at 10:03.
+- **Generating an image on desktop from the phone** — not built. Wanted, deferred past this release.
+
+## Confirmed working
+
+- Projects and chats converge.
+- Model settings sync.
+- Clipboard iPhone → desktop.
+- Attachments desktop → android.
+
+## Open questions for Anurag
+
+- Does the slow desktop reply reproduce for a message typed on the desktop itself, or only for one that
+  arrived from the phone?
+- How old is the desktop profile that needed the receive categories switched on? A profile created before
+  the default flipped explains it; a fresh one would make it a real defect in the desktop default.
+
+## Community report — a model that will not load
+
+Against a previously shipped release, on a device the reporter still uses.
+
+- **Muse Glimmer 30B fails to load; Qwen3.6-27B of similar size loads fine on the same device.** Tried
+  both the official Meta GGUF (K-quant, 17 GB) and the Unsloth quants.
+
+  The reporter's own diagnosis is the likely one and is worth stating as theirs, not ours: Muse Glimmer
+  introduced a new architecture (`muse-glimmer`) merged into llama.cpp on release day, 2026-08-10. A
+  runtime that predates that commit does not know the architecture, which is exactly the shape of "this
+  model refuses while older ones work".
+
+  **Confirmed in our own tree.** `muse-glimmer` appears nowhere in the llama.cpp that llama.rn 0.12.9
+  bundles - zero files under `node_modules/llama.rn/cpp`, against a control of 35 files mentioning
+  `qwen3` and `LLM_ARCH_QWEN3` declared in `llama-arch.h`. The runtime we ship cannot know the
+  architecture, so the reporter is right and no device-side setting will change it.
+
+  **Meta's own numbers put this model on the desktop** (research.meta.ai, 2026-08-10): 30B, Apache 2.0,
+  multimodal with "a dedicated perception encoder" and interleaved text and images. Full precision "would
+  require over 55 GB of memory"; at 4-bit "under 20 GB", fitting "a 24 GB or 32 GB envelope" on a consumer
+  GPU. The target it names is "Mac or PC with a single consumer GPU". It ships a DFlash "drafter" for
+  speculative decoding, quoted at 3.1x on an RTX 5090 and 1.5x on an M4 Max.
+
+  That reframes the report. No phone has a 24 GB envelope, so the mobile attempt could not have succeeded
+  whatever the runtime - the llama.rn gap is real but SECONDARY, and the honest answer to that reporter is
+  that Android cannot hold this model, not that we are behind on a dependency.
+
+  Desktop is where it is viable, and there the path is short: llama.cpp b10369 (2026-08-12) knows
+  `muse-glimmer`, and the perception encoder rides the mmproj path desktop already has for vision models.
+
+  Two things the upgrade alone will not solve:
+
+  - **The model needs a perception encoder passed at load**, the same shape as the mmproj path vision
+    models already take. Support in the runtime is necessary and not sufficient - the app has to hand it
+    over. Speculative decoding additionally wants a companion drafter model.
+  - **30B does not fit a phone.** Full precision is 55 GB+, and the 17 GB K-quant the reporter tried is
+    still far past any handset. Whatever the runtime knows, the memory gate should be refusing this with
+    a reason the user can read, and "fails to load" suggests it is not saying which of the two is wrong.
+
+  Meta's stated floor is llama.cpp build b10353 or newer, so that is the number to check against whatever
+  llama.rn release we land on.
+
+## Runtime upgrade — decided 2026-08-12
+
+**Mobile is on `llama.rn` 0.13.0-rc.0 now.** That buys Nemotron 3.5 (`nemotron`, `nemotron_h`,
+`nemotron_h_moe`). It does NOT buy Muse Glimmer: neither `muse-glimmer` nor `granite-switch` appears in its
+bundled `cpp/`.
+
+**Muse Glimmer on Android waits for upstream.** llama.rn PR #379 syncs to llama.cpp b10362 and names Muse
+Glimmer support; it is open, its checks pass, and the sync looks like a daily automated job. A merge alone
+is not enough - the postinstall pulls the prebuilt `rnllama.xcframework` and `jniLibs` from the MATCHING
+release, so a PR-branch install would have no artefacts and we would have to build the native side
+ourselves.
+
+Decision: **check again immediately before the release.** If a release carries it, bump the pin. If not, it
+goes in the next one. Desktop already has it via `b10369`, so the model is testable there today.
+
+## Runtime upgrade verification
+
+- **Verify the pinned llama.rn 0.13.0 release candidate.** The app pins `0.13.0-rc.0`. New llama.cpp
+  architectures arrive only through this dependency, so every "new model will not load" report ends here.
+
+  Three things to weigh before taking it:
+
+  - It is a release CANDIDATE, and its own CI badge reads failing on the page. A pinned rc in a shipping
+    app is a choice, not an upgrade.
+  - 0.13 does not promise the `muse-glimmer` commit. The floor is llama.cpp b10353; grep the candidate's
+    `cpp/` for the architecture rather than trusting the tag - it took one grep to disprove 0.12.9.
+  - New Architecture is already on (`newArchEnabled=true`), so the v0.10 requirement is met.
+
+  It also reaches the Hexagon NPU assets and the TTS surface, so it is not a drop-in bump: the HTP kernels
+  in `android/app/src/main/assets/ggml-hexagon/` come from this runtime, and Gemma is already known to
+  garble on HTP.
+
+## Pro user report — Pat, 2026-08-12
+
+Against a PREVIOUSLY SHIPPED release, so both defects below are live for paying users now.
+
+### Defects
+
+- **A reinstall costs a mesh seat.** Pat reinstalled Off Grid Pro on ONE Android device, entered the Pro
+  key, and the roster now reads "devices 2 of 5". Both entries are the same physical phone; the first
+  install is gone. He asks whether it can be reset, or whether the key only activates five times.
+
+  **Diagnosed, and deliberately not fixed - it needs your call.** Two things are true:
+
+  - `meshReclaim` (`shared/.../control-center.ts:742`) returns early below the cap:
+    `installations.length < PERSONAL_MESH_DEVICE_CAP`. At 2 of 5 nothing reclaims, by design.
+  - `isUnclaimedSeat` means "the installation has NO syncDeviceId". Pat's ghost has one - the old
+    install's fingerprint - so it is not unclaimed. It is ORPHANED, and only the first kind has a name,
+    which is why nothing can act on the second.
+
+  The unsafe fix is the tempting one. From one node, "no live device answers to this seat" cannot be
+  distinguished from "that device is offline, or paired with another node and not with me" - a five-device
+  mesh does not pair every node to every other. Acting on that would evict a device someone still uses,
+  which is the one outcome worse than an inflated count.
+
+  What would make it safe is an identity that survives reinstall, so a phone can say "that seat was mine".
+  That is a product decision about device identity, not a patch, so it is written down rather than guessed
+  at.
+
+- **"LLM is busy" when switching from text to voice, and voice arrives slowly on a matched device.** Pat
+  reports the Android app as sometimes choppy.
+
+  **Cause found, and this codebase documents the contradiction itself.**
+  `generationServiceHelpers.ts:183` refuses the send when `waitForIdle()` comes back false, and that wait
+  is bounded at 15 seconds (`llm.ts:437`). Two comments in the same tree record a **74-second CPU prefill
+  on-device** (`generationToolLoop.ts:886`, `llmToolGeneration.ts:251`). So a perfectly healthy long
+  prefill reads as "busy" - and the slowness Pat reports is the same prefill, seen from the other side.
+
+  Not changed unverified, because it is generation timing on a hot path and there are two candidate fixes
+  with different risks:
+
+  - Raise the bound. Cheap, and picks another arbitrary number that some device will exceed.
+  - Wait on PROGRESS instead of total elapsed time. A stuck engine is one that has stopped moving, which
+    is not the same thing as one that is taking a while - and it is the condition the guard was actually
+    written for. `activeCompletionPromise` is swallow-wrapped and always settles, so the engine finishing
+    is already a reliable signal.
+
+  The second is the right shape. It wants a device round before it ships.
+
+  His closing advice is worth recording as given: spend a few hours using the app on real devices.
+
+### Requests, not defects
+
+- **Linux and Windows builds.** Windows now exists as a nightly; Linux does not.
+- **Share a phone's GPU with the desktop, or expose the phone as an API.** Wanted, unbuilt.
+- **Hosted GPU as an offering.** Out of scope for an on-device product, and worth answering plainly rather
+  than leaving open: the promise is that data stays on the user's devices.

+## A tool-heavy turn's FINAL ANSWER reaches peers LONG after its tool calls do
+
+**Verdict:** instrument-and-revisit — the delay is real and large; the trigger is unknown.
+
+Observed 16 Aug 2026, run `iostools20260816161658`, guided six-tool journey driven from iOS.
+
+iOS finished the turn completely: thinking block, six tool calls, and a full answer
+("Off Grid AI & OGAM — Complete Overview", OGAM as a Product, Business Metrics…). macOS and
+Windows both hold the same conversation and **every tool call**, read straight off each desktop:
+
+```
+messageCount: 16, hasMarker: true
+tail: … read_wiki_structure Completed in 1611 ms / read_wiki_contents Completed in 3872 ms /
+      ask_question Completed in 17045 ms / search_knowledge_base Completed in 550 ms /
+      search_knowledge_base Completed in 758 ms / ask_question Completed in 14718 ms
+hasOgamOverview: false
+```
+
+At that moment the transcript on both desktops ENDED at the last tool call, with no assistant
+message after it. It did arrive later - Mac saw it appear on every device some minutes afterwards -
+so this is LATENCY, not loss. The delay was long enough to read as a failure while watching.
+
+How long, and what finally triggered it, are NOT yet measured. A first reading claimed the answer
+never synced; that was wrong, and a second reading could not be compared because the desktops had
+moved to a different conversation by then. Measure it properly before theorising: stamp the moment
+the primary settles, then poll ONE peer on that same conversation until the answer appears, and
+report the interval.
+
+**Why it matters:** the mesh looks healthy. The conversation is there, the tool activity is there,
+timings are there. A user on their Mac sees a turn that apparently did a lot of work and concluded
+nothing. It reads as the model failing, not as sync dropping the last message.
+
+**Where to start:** whatever writes tool-result/artifact events syncs; the terminal assistant
+message for a long tool-using turn does not. Compare against the plain `run-normal` journey, whose
+final answer DOES reach all four devices - so this is specific to the tool-heavy path or to message
+size, not to sync in general.
+
+---
+
+## "Preparing reply" state never reaches peer devices
+
+**Verdict:** instrument-and-revisit.
+
+While the primary device is working, peers show nothing. There is no "preparing reply" or thinking
+indicator on the other devices, so a person watching their desktop cannot tell the difference
+between "my phone is mid-answer" and "nothing is happening". Reported by Mac, 16 Aug 2026, during
+the guided journey.
+
+Related to the entry above: the peers do eventually receive tool events, so SOMETHING streams -
+what is missing is any signal that a turn is in flight.
+
+---
+
+## DeepWiki `ask_question` returns a validation error
+
+**Verdict:** fix-the-guard.
+
+In the guided six-tool run the model reported, in its own thinking:
+
+```
+ask_question - FAILED due to validation error, but the tool was attempted/triggered
+```
+
+The desktops show `ask_question Completed in 17045 ms` and again `Completed in 14718 ms`, so the
+call is dispatched and returns - it is the arguments or the response shape that fail validation,
+not the transport. Five of the six named tools (search_knowledge_base, web_search, read_url,
+read_wiki_structure, read_wiki_contents) succeeded in the same turn.
+
+Worth checking what the DeepWiki MCP server expects for `ask_question` against what is being sent.
+
+---
+
+## Test coverage we know we are missing (Mac's list, 16 Aug 2026)
+
+**Verdict:** instrument-and-revisit — none of these are known failures. They are capabilities we
+ship and do not exercise, which is how today's defects survived: the PDF-in-a-message bug had been
+predicted from a diff for VOICE NOTES weeks earlier and was only found when someone actually sent
+one.
+
+### Models and hardware
+
+- **Huge models — eviction and co-residency.** Run with something like Qwythos 9B (5.5 GB) and prove
+  eviction and co-residency behave: what gets unloaded, what survives, and that the device does not
+  die instead of evicting. iOS matters most here - a memory breach there is an uncatchable jetsam
+  SIGKILL, so the engine's GPU→CPU→CPU@2048 ladder cannot save it.
+- **GPU and NPU selection.** Prove the chosen backend is the one actually used, read back from
+  "show generation details" rather than assumed from a setting.
+
+### Voice
+
+- **Voice mode end to end** - STT in, TTS out, on a real device.
+
+### Clipboard
+
+- **Copying OUTSIDE the app** reflects in the in-app clipboard, on both Android and iOS.
+
+### Ambient sharing, both ways round
+
+Each of these needs the negative case as well as the positive, because a permission that fails open
+is invisible when you only test that sharing works:
+
+- screenshots ARE synced when allowed / are NOT synced when disallowed
+- downloads ARE synced when allowed / are NOT synced when disallowed
+
+### Model transfer between devices
+
+- image models send and WORK on the receiver
+- vision models send and WORK on the receiver
+- text models send and WORK on the receiver
+- STT models send and WORK on the receiver
+- the right models are offered to send, based on what the RECEIVER is
+
+"Arrives" and "works on the receiver" are different claims, and only the second one is the feature.
+
+### The ones Mac's list did not name, ranked by what they would cost us
+
+Highest risk first, because these are the ones where the failure is silent or unrecoverable rather
+than merely wrong.
+
+1. **Peer-pushed model settings, with no device-fit check.** `contextLength`, `maxTokens`,
+   `gpuLayers`, `nThreads` and `nBatch` are writable by a paired desktop and validated for TYPE and
+   RANGE only - never against what the receiving device can actually honour. Desktop offers maxTokens
+   up to 32768 and ctxSize up to 131072; a phone sitting at 4096 accepts them. The mutations are
+   per-key, so a maxTokens change alone lands on a phone whose context never moved, giving
+   `n_predict > n_ctx` - llama.cpp rejects the turn before inference while the settings screen still
+   reads 4096. On iOS the memory case is worse than wrong: a breach is an uncatchable jetsam
+   SIGKILL, so the engine's GPU→CPU→CPU@2048 fallback ladder cannot catch it. There is in-repo
+   precedent - appStoreMigrations.ts documents a removed MCP auto-boost that pinned context to 32768
+   and caused OOM crashes needing a repair migration. Sync can now reproduce that state from a peer,
+   with no migration to undo it. **Test: push each of those keys from desktop to a phone that cannot
+   honour them, and to an iPhone specifically.**
+
+2. **`maxToolCalls` is synced as well.** A peer set to 1 turns a single-tool request into a "tool
+   limit reached" notice instead of an answer. The default also moved from 3/5 to 25.
+
+3. **"Arrives" and "works on the receiver" are different claims.** Worth stating explicitly against
+   every transfer item above: only the second one is the feature. A model that lands and will not
+   load is a failure that a transfer test scores as a pass.
+
+4. **Every non-image attachment kind except PDF.** describeAttachment now classifies audio and video,
+   but only PDF has been SEEN working end to end. The voice note is the exact case this defect was
+   predicted for in the v0.0.103 review and it remains unproven on desktop.
+
+5. **A receiver that does not already have the model** - the download-on-demand path, as distinct
+   from transfer between two devices that both happen to have it.
+
+6. **Interrupted transfers** - background the app, drop wifi, lock the phone mid-send, then resume.
+
+7. **Offline behaviour.** Entitlement reconciliation reports "License service unavailable" with no
+   network. Prove offline access genuinely stays usable rather than degrading into a lock-out - the
+   home screen already had one of those, where a card that was still loading had no way into Sync.
+
+8. **The five-device replacement flow** at the licence limit, including the failure mode where the
+   oldest membership cannot be removed (`replacement_incomplete`).
+
+9. **The vision journeys still only run from Android.** vision-image-sync and vision-answer-sync are
+   Android-hardcoded. The iOS system photo picker exposes no addressable cells - only PXG* layout
+   groups and one concatenated label - so the iOS path needs the geometric-tap approach now used in
+   multi-attachment-sync.
+
+---
+
+## Model memory: the estimate is unscientific, inconsistent, and fails silently
+
+**Verdict:** fix-the-guard — three defects in one decision, found together on 16 Aug 2026 when
+Qwythos 9B (5.5 GB) would not load on an iPhone and the chat sat unusable with no explanation.
+
+### 1. The estimate ignores context length, which is the term that actually varies
+
+```ts
+estimateModelRam(model, multiplier = 1.5) {
+  return this.getModelTotalSize(model) * multiplier   // file size only
+}
+```
+
+Observed: `[MEM-SM] makeRoomFor text sizeMB=12387 budgetMB=9121 os_procAvailMB=5189 fits=false`.
+That 12387 is 5632 MB x 2.2. Reducing the context length to ~1k made the same model load
+immediately - the gate never saw the change, because context is not an input to it.
+
+Real memory decomposes as:
+
+```
+total = weights + KV cache + compute buffer + slack
+KV_bytes = 2 x n_layers x n_kv_heads x head_dim x n_ctx x bytes_per_element
+```
+
+Only WEIGHTS scale with file size. For a 9B with ~48 layers and GQA (8 KV heads x 128), f16 KV is
+roughly 196 KB per token: ~0.2 GB at 1k context, ~1.5 GB at 8k, ~6.3 GB at 32k, ~25 GB at 128k. A
+single file-size multiplier is being asked to hide a 100x spread, so it must be wrong in one
+direction or the other - it refuses big models that would fit at small context, and admits small
+models at 131072 context that will not. On iOS the second case is an uncatchable jetsam kill.
+
+Everything needed is already available: the GGUF header carries block_count,
+attention.head_count_kv, attention.key_length/value_length and context_length; llama.cpp prints its
+own tensor, KV and compute buffer sizes at load; and `[WIRE-RAM] footprintBytes` is already logged
+after every load, so predicted-vs-real can be calibrated per backend from real runs. This is how
+Ollama's scheduler decides layer offload, and what the HF/LM Studio calculators do.
+
+### 2. The multipliers are not derived from anything
+
+`TEXT_MODEL_OVERHEAD_MULTIPLIER = 1.5` is commented only "CPU: KV cache, activations, etc."
+`TEXT_MODEL_GPU_OVERHEAD_MULTIPLIER = 2.2` was chosen to "mirror the image estimator's
+ANE(1.8)->GPU(2.5) bump" after ONE device incident (2026-07-14, 8.2 GB estimated against 11.4 GB
+real). The file above them records that flat percentages were removed because they "wrongly treated
+a 12GB iPhone like a 6GB one" - a flat multiplier makes the same mistake one level down, treating
+every model's runtime shape as proportional to its file.
+
+### 3. Two owners compute it differently, and one of them fails silently
+
+```ts
+// modelPreloader.ts - default 1.5x, and a bare return
+const sizeMB = toMB(hardwareService.estimateModelRam(model));
+if (!modelResidencyManager.canLoadWithoutEviction({ key: 'text', sizeMB })) return;
+
+// activeModelService/index.ts - backend-aware 2.2x on GPU
+estimateModelRam(model, textOverheadMultiplier(store.settings.inferenceBackend))
+```
+
+For Qwythos that is 8448 MB versus 12387 MB - the preloader believes it fits and the authoritative
+gate refuses. Two answers to "how much memory does this model need", kept in step by hand.
+
+**No silent drops.** A refusal is a decision the user has to be told about. Today the only trace was
+`fits=false` in a debug log, while the chat still said "Type a message below to begin chatting with
+Qwythos" - a model that was never coming. Whatever the gate decides, the surface must say so, name
+the numbers (needs X, budget Y, free Z), and offer the actionable next step - lower the context
+length, choose a smaller model, or free memory - rather than leaving a chat that looks ready and is
+not.
+
+### How to fix it: one owner, a real formula, and a card that tells the user
+
+**One owner.** memoryBudget.ts is already documented as "the single memory-budget owner ... so
+residency, the pre-load check, and the model lists all agree". The ESTIMATE needs the same
+treatment: one `estimateModelMemory({ model, contextSettings, backend })` that modelPreloader,
+activeModelService, the model lists and the UI all call. Today modelPreloader answers 8448 MB and
+activeModelService answers 12387 MB for the same model.
+
+**A real formula.** PocketPal (github.com/a-ghorbani/pocketpal-ai, src/utils/memoryEstimator.ts)
+does exactly the decomposition, and it is worth copying:
+
+```
+total = (weights + KV cache + compute buffer) * 1.1        // 1.1 on a COMPUTED number
+KV    = n_layers * effectiveCtx * n_embd_head_k * n_head_kv * bytesPerK
+      + n_layers * effectiveCtx * n_embd_head_v * n_head_kv * bytesPerV
+compute = (n_vocab + n_embd) * n_ubatch * 4
+fallback when GGUF metadata is missing = size * 1.2
+```
+
+Details they get right that a multiplier cannot express:
+
+- KV cache quantisation is exact, not assumed: f16 2.0, q8_0 1.0625 (34/32), q4_0 0.5625 bytes per
+  element, and K and V are computed separately because they can be quantised differently.
+- Sliding-window attention: `effectiveCtx = min(n_ctx, sliding_window)`, so a Gemma-style model is
+  not charged for KV it will never allocate.
+- The mmproj (vision projector) is added separately rather than folded into a multiplier.
+- Metadata is validated first (NaN / non-positive / missing), falling back to size * 1.2 rather than
+  silently computing nonsense.
+
+Their BUDGET side is calibrated rather than assumed:
+
+```
+ceiling  = max(largestSuccessfulLoad, availableMemoryCeiling)
+fallback = min(totalMemory * 0.6, totalMemory - 1.2GB)
+status   = fits | warning (fits in total but not in ceiling) | will not fit
+```
+
+They learn the ceiling from the largest model that has actually loaded on that device. We already
+log `[WIRE-RAM] footprintBytes` after every load, so the same calibration is available to us - the
+difference is we throw the measurement away and they keep it.
+
+**A card that tells the user.** MtpAdviceCard is the existing in-chat pattern: dismissible, a title,
+and ONE action ("Turn on speculative decoding and reload the model"), rendered from ChatMessageArea.
+A memory refusal belongs there, naming the numbers and the way out:
+
+  "Qwythos 9B needs about 12.4 GB at 32k context. This device has 12 GB."
+  -> Reduce context to 8k and load  /  Choose a smaller model
+
+Silence is the defect. Today the only trace of the refusal was `fits=false` in a debug log while the
+chat said "Type a message below to begin chatting with Qwythos" - a model that was never coming.
+
+---
+
+## A synced file can deadlock: bytes arrive, control never re-applies (16 Aug 2026)
+
+**Symptom, from the device.** An image generated on iPhone rendered on macOS, Windows and iOS but
+stayed a spinner on Android. The gallery counted it (`1`) while the grid showed nothing - the file was
+staged but never imported.
+
+**The evidence (Android logcat, 21:02:33):**
+
+```
+[StateSync] ops from=9d25c24e received=1 applied=0 shared_file:1
+transfer_offer_accepted  resumeOffset=504593  delivered=true      <- already had every byte
+shared_file_decided      result=waiting_for_control  reason=control_missing
+transfer_settled         status=completed  bytes=504593
+```
+
+`received=1 applied=0` repeats. Per `state-sync.ts:102`, that means the op was ALREADY KNOWN.
+
+**The loop.** It is self-sustaining and silent:
+
+1. Android holds the bytes AND holds the `shared_file` control op in its oplog.
+2. `ControlledFileSync.controls` (an in-memory `Map`, `controlled-file-sync.ts:204`) has no entry for
+   that syncId, so reconcile answers `control_missing`.
+3. `sharedFileSyncService.ts:337` correctly asks the peer to repair the `control`.
+4. The peer answers by re-announcing (`shared-file-repair.ts:320`). `OpLog.record` returns the
+   already-recorded op unchanged, so it carries the SAME opId.
+5. Android dedups it by opId -> `applied=0` -> the materializer never fires -> `applyControlPut` is
+   never called -> the map stays empty. Back to 2, forever.
+
+**This is the SSOT failure `shared/CLAUDE.md` describes.** Two sources answer "does a control exist for
+this file": the durable oplog (yes) and the in-memory `controls` map (no). They are kept in step by
+hand - the map is only ever written by an op that APPLIES - so any op already in the log leaves the map
+cold, and version vectors then stop the peer from ever helping. `oplog.ts:198-200` names this exact
+hazard: "an ephemeral materializer cannot recover and peers correctly decline to resend already-seen
+ops."
+
+**Not mobile-specific.** `controlled-file-sync.ts`, `oplog.ts` and `shared-file-repair.ts` are all in
+`@offgrid/sync`. Every host shares the defect; Android is the device that hit the cold-map condition.
+
+**Still open - why the map was cold.** `stateSyncService.ts:217` DOES call `rematerializeAll()` on
+start, which should rebuild it. Two untested candidates:
+- `parseControl` returned null on replay, so `applyControlPut` returned `"ignored"` and never set the
+  map (`controlled-file-sync.ts:222`) - a silent drop by itself.
+- `compact()` (`stateSyncService.ts:221`) dropped the superseded control op while the version vector
+  kept claiming it, so there is nothing left to replay but peers still refuse to resend.
+
+**The fix shape (do not implement yet).** Make the durable log the only source: rebuild `controls` by
+replaying the log, and make a `control` repair request force re-materialisation of that syncId rather
+than re-broadcasting an op the peer will discard. A repair that cannot make progress must surface -
+a file waiting on a control that will never come is exactly the silent drop we said we cannot afford.
+
+**Cover it.** No test asserts a control arriving BEFORE its bytes and then the app restarting, which is
+the shape of this bug.

+## The selected text model is never resident on a 3-model device (16 Aug 2026, iPhone)
+
+Found by `scripts/e2e/model-eviction-journey.mjs`, which walks residency up one model at a time and
+reads the app's own Models sheet between each step.
+
+```
+1. at rest                             image + voice + speech
+2. after a typed turn                  image + voice + speech
+3. after a spoken turn                 image + voice + speech
+4. after an image request              image + voice + speech
+
+never resident at any stage: text
+  text    Qwythos-9B-v2-GGUF                (selected, never loaded)
+* image   3.6 GB  SD 1.5 Palettized (Core ML)
+* voice   0.3 GB  Kokoro TTS · Warm
+* speech  0.1 GB  Base
+```
+
+Three sidecars hold 4.0 GB and the model the user chose cannot get in. The app still answers and still
+draws, so nothing on screen says the chosen model is not the one running - except one in-chat line,
+captured on device:
+
+> Prompt enhancement skipped - Generating from your original prompt - Not enough free memory to load
+> this model. Close other apps or choose a smaller model.
+
+That message is right, and it is the only signal. It does not name what was needed, what was
+available, or what would fix it, and it appears only on the enhancement path - a plain chat turn with
+the same problem says nothing at all.
+
+**Ties directly to the memory-estimate work above.** The refusal is the estimator's verdict reaching
+the surface. Two questions this run raises that the current estimator cannot answer:
+
+- Would the text model fit if the image model (3.6 GB, idle) were evicted first? Nothing appears to
+  consider that trade - the image sidecar stays resident across every stage including two turns that
+  never needed it.
+- Qwythos loaded earlier in the same session once the context was lowered to 1k, which the gate's
+  cost model cannot express, since it is context-blind. Still unexplained, still open.
+
+**Cover it.** The journey is the regression test: any change to the cost model should be run against
+it, and `never resident at any stage: text` should become empty.
+
+
+## Voice: hands-free, barge-in and note trimming — 2026-08-17
+
+Built and merged in one session on `release/sync-feedback`. **None of it is device-verified**; the
+notes below say exactly which part is proven and how.
+
+### Open
+
+- **Desktop consumes none of it.** `@offgrid/speech` now owns the turn decision
+  (`SpeechEndpointTimer`, `canArmHandsFreeTurn`), the mode labels, the onset look-back and the WAV
+  trim math. Mobile uses all of it; desktop uses none. Parity was asked for explicitly, so SSOT here
+  is structural only until desktop's recorder is wired to the same package. **This is the top item.**
+- **Barge-in is NOT possible on this audio stack, and the attempt is backed out.** Talking over the
+  assistant cannot interrupt it. An AVAudioSession MODE is only a hint; real cancellation needs the
+  voice-processing I/O unit driving INPUT and OUTPUT together so it has a reference for what the
+  speaker plays. Our TTS goes out through an ordinary `AudioContext`, which that unit never sees, so on
+  device the mic recorded the assistant and speech detection fired on the assistant's own voice - iOS
+  AND Android alike. The Oboe `VoiceCommunication` patch was reverted for the same reason: it asks for
+  a cancelling capture source while playback leaves by another path, so it bought nothing and carried a
+  blank-audio risk on some devices (google/oboe#2123). `audioRecorderService.isEchoCancelled()` is the
+  single owner and returns false; when playback and capture share a voice-processing engine it returns
+  true and hands-free listens through the assistant with no other change. **Real fix: give TTS playback
+  and mic capture one voice-processing engine** - native/library work, not a setting.
+- **Voice processing degrades PLAYBACK, which is how TTS went silent.** `ensurePlayback` deliberately
+  leaves an active record session alone, so one recorded turn in a voice-processing mode left every
+  later playback voice-processed. Ordinary turns no longer request it. Guard rows are on the release
+  checklist (#202, #203).
+- **THE design gap: speaking and listening are not serialized.** They are one resource with one
+  holder - the assistant or the person, never both - and the code models them as two independent
+  subsystems (TTS state in `pro`, mic phase in core) with a 400ms poll guessing when it is safe. Every
+  fault today came from that: TTS pausing the moment it started (the mic armed in the gap between
+  generation ending and speech beginning), autoplay killed by an arm, the assistant recorded as the
+  person. The settle-ticks and abandon-guard in `useHandsFreeArming` are symptoms, not a design.
+
+  **The shape it wants:** one owner of the floor with event-driven handoff -
+  `assistant speaking → person listening → recording → transcribing → generating → assistant speaking`.
+  Exactly one holder; illegal states (mic open while speaking, two turns at once) become
+  unrepresentable instead of raced against.
+
+  **What forces the poll:** there is no "the assistant finished speaking" EVENT. Core cannot subscribe
+  to pro's TTS state, so `audio.isSpeaking` is a question that must be re-asked. Needs an
+  `audio.onSpeechEnded` hook fired by pro on playback completion, a floor owner in core that serializes
+  transitions, and `useHandsFreeArming` collapsing into a listener on it rather than a timer. Three
+  files, no new behaviour - it makes today's behaviour correct by construction instead of by timing.
+  **Desktop should be wired to the floor owner, not to the poll.**
+
+- **Idle hands-free stalls rather than ends.** The wait for speech is 120s, so two devices left
+  pointing at each other both go quiet and it reads as frozen, not finished.
+- **`@offgrid/speech` is a mixed package.** It was a gateway speech client (console/desktop) and now
+  also holds on-device turn logic. Same domain, but the name promises less than it holds.
+
+### Verified, and how
+
+- **WAV trim math** — proven in node against real WAV bytes, not on device: chunk-walking finds `data`
+  behind a LIST chunk (offset 70), a 1.5s cut of a 2s file yields `copyFrom 48044 / copyBytes 16000`,
+  the rewritten header declares the kept length, and garbage / over-trim / zero-trim are all refused.
+  The **file I/O around it is NOT verified** — no trim has run on a device.
+- **VAD auto-stop** — verified on device earlier in the session, with rms/floor/speech in the log.
+
+### Fixed while doing this, worth knowing
+
+- `recordingController.stop()` required phase `'recording'` while `toggle()` offered to stop a
+  `'listening'` turn, so stop was silently refused mid-listen. Live in every hands-free build before
+  `42147394`.
+- Phase had two writers (endpoint + recorder) that could disagree; callers now report facts and the
+  controller derives. `echoCancelled` was hardcoded `true` away from the code that configures capture;
+  the recorder owns it and derives iOS's answer from the session mode actually applied.
+
+### Open, added while making the voice delays user-chosen + putting replay in the session
+
+- **Trailing silence is not trimmed.** `finaliseRecording` calls `trimWavFront` only, so the person's
+  chosen end-of-turn window (up to 5s of dead air) rides into every file and Whisper transcribes
+  through it. The tail cut belongs in the same pure planner (`wav-trim.ts`), keeping ~300ms of
+  hangover so the last syllable is not clipped. Shortening the window in settings shrinks the tail but
+  does not remove it.
+- **Post-reply hand-back overhead beyond the drain is unmeasured.** The chosen drain accounts for the
+  speaker's tail; whatever the device adds on top (mic spin-up, audio-session switching) has never been
+  read off a real log. Measure before tuning anything.
+- **Replay-in-the-session and the two delay settings are code-complete, NOT device-verified.** The
+  machine transitions are pure and typecheck/lint/package tests are clean, but no phone has run them:
+  the replay-while-listening contention, the paused-replay hand-back, and the settings rows all need
+  the on-device pass.
+- **Queued outbound transfers do not follow a peer to its new address, and never expire.** Seen live:
+  the phone's pending WAVs all say "To OGAD x.x.x.64" while discovery is finding the same Mac at
+  .31 - inbound from .31 completes in seconds, outbound to .64 sits at 0% forever. The durable
+  SQLite op-store makes these rows survive restarts (correctly), which turns two missing rules into
+  a permanent pileup: (1) re-target queued items when the same device id is rediscovered at a new
+  host - the sibling of the existing "follow a peer that comes back on a new port" fix; (2) an
+  expiry/failed transition for a peer that stays unreachable, instead of pending-forever.
+- **A sender dying mid-batch leaves the receiver full of zombie rows.** Seen live: desktop was
+  sending a 90-item batch (its log shows one file importing every ~3s, serial); the desktop process
+  was killed mid-batch and Android's Sync activity froze with 35 rows at "Receiving - 0%, 0 B" from
+  the vanished peer. Two defects, both SSOT-shaped: (1) receiver rows are created at OFFER time and
+  nothing reconciles them when the sender disappears - no timeout, no failed transition, they sit
+  "in progress" forever; (2) admission marks the whole batch in-progress up front while transfer is
+  actually serial, so "35 in progress" describes the queue, not the wire. Any crash or quit
+  reproduces this; it does not need a kill.
+
+## Voice: the three RED realtime tests are GREEN, but NOT device-verified (2026-08-18)
+
+All three had ONE root cause. `recordingController.start()` both dispatched `userStart` - which the
+session driver obeys by opening the microphone - AND called `handlers.start()`. One tap therefore ran
+`startRealtimeTranscription` twice and entered the native `transcribeRealtime` twice while the first
+session was still coming up. That is the "State: -100" collision (B12), and it never needed a
+double-tap. Stack-captured at the boundary, not inferred.
+
+Fixed: a synchronous in-flight latch in `useWhisperTranscription` (the old guard read `isRecording`
+from a closure and `whisperService.isTranscribing` was only set after an await for permissions, so two
+asks fit inside the window); `useVoiceSessionDriver` made edge-triggered, which is what its contract
+already claimed; `nextVoiceSession` `userStart` made a no-op when already listening.
+
+**Still owed: a device pass.** Every symptom in this area's history (B12, B26, B28) was device-only, and
+these fixes are verified against faked native leaves. Three flows to run on a phone:
+1. Text model resident, tap mic, speak - does the transcript land? (was the silent-empty-composer case)
+2. Tap the mic twice quickly - any "State: -100", or does the transcript arrive?
+3. Fresh voice-model download, then tap mic - does the spinner become a live recording?
+
+**Do not make `useVoiceSessionDriver` level-triggered again.** `voiceSession.dispatch` notifies on a
+phase change so the hero can show "Recording you now"; with a level-triggered driver that same
+notification opens a second recording mid-turn. The two belong together and each says so in a comment.

+# Brief: drive the Off Grid mesh E2E suite from iOS
+
+You are running the physical-device E2E suite in `/Users/user/wednesday/off-grid-ai/mobile`
+(branch `release/sync-feedback`), with the **iPhone as the producer** and the other devices as
+observers. Everything below was learned on the hardware; each fact cost real time to find, so read
+it before you touch anything.
+
+## The rule that matters most
+
+**Do not reset, delete, stash, or force-push anything.** Every repo in
+`/Users/user/wednesday/off-grid-ai` holds unrelated in-progress work. Commit only files you changed
+yourself, and only when the change is finished.
+
+Report status as a gate — *code / wired / verified*. A journey is not passing until you have watched
+it pass. Do not report a run as green because it "should" be.
+
+## The four devices
+
+| Surface | How it is reached | Notes |
+|---|---|---|
+| iPhone | WebDriverAgent on the phone's OWN address, currently `http://192.168.1.14:8100` | iPhone 17 Pro Max, UDID `4CF4A291-280A-598C-8AC5-851073C14B30`, app `ai.offgridmobile.dev` |
+| Android | adb + Appium (`http://127.0.0.1:4723`) | serial `505b53a0`, package `ai.offgridmobile.dev` |
+| macOS | Chrome DevTools Protocol on `http://127.0.0.1:9222` | the Electron app running on this Mac |
+| Windows | CDP on `http://127.0.0.1:9224` | an SSH tunnel to `oga@192.168.1.26`; the port is bound to localhost ON the Windows box, so `192.168.1.26:9224` will look dead. Check the tunnel with `pgrep -fl "ssh.*9224"` |
+
+Confirm all four before a long run. A journey that dies 20 minutes in because a surface was down
+wastes the run and reads like a product failure.
+
+## Bringing WebDriverAgent up
+
+```bash
+cd /Users/user/wednesday/off-grid-ai/mobile
+WDA_UDID=4CF4A291-280A-598C-8AC5-851073C14B30 nohup node scripts/ios/launch-wda.mjs > /tmp/wda.log 2>&1 &
+```
+
+- **The launcher process IS the server.** If it exits, WDA dies. Do not run it in a foreground shell
+  that will be torn down.
+- `setsid` does **not** exist on macOS — `nohup` alone.
+- It prints `WDA serving at http://<phone-ip>:8100`. The IP can change; read it from the log rather
+  than assuming.
+- **The phone must be UNLOCKED with Auto-Lock set to Never**, or WDA is suspended mid-run.
+- Build + install + launch takes a few minutes. Wait for `/status` to answer.
+
+### After any WDA restart, create a session FIRST
+
+The rig's `WdaClient.attach()` deliberately *reuses* an existing session so it never relaunches the
+app and loses its mesh identity. A freshly started WDA has no session, and you get
+`WDA has no active session to attach to`. Create one:
+
+```bash
+curl -s -X POST http://<phone-ip>:8100/session \
+  -H 'Content-Type: application/json' \
+  -d '{"capabilities":{"alwaysMatch":{"bundleId":"ai.offgridmobile.dev","shouldWaitForQuiescence":false}}}'
+```
+
+## The suite
+
+Everything modified **14 Aug 2026 or later** is the active mesh suite. The older files (11 Aug) are
+the separate sync/pairing suite and are not part of this job.
+
+| Journey | What it proves | iOS-primary state |
+|---|---|---|
+| `attended-thinking-sync` | staged: normal message, thinking on/off, project + Knowledge Base, guided six-tool run | `run-normal` **works** (fixed); `send-guided-tools` already had an iOS path; `prepare-project` **blocked** (see below) |
+| `generated-image-sync` | image generation from a text prompt | **Android-hardcoded** — needs the same treatment as `run-normal` |
+| `vision-image-sync` | attach a photo, describe it, generate from what was read | **Android-hardcoded** (adb + Appium + the Android photo picker) |
+| `vision-answer-sync` | attach a photo, text answer only, no image | **Android-hardcoded**, same reason |
+
+`attended-thinking-sync` is staged on purpose: one visible action per command, with the send guarded
+by durable state so a rerun after a UI failure cannot submit the same prompt twice.
+
+### Running the staged journey
+
+```bash
+RUN=iosnormal$(date +%s)
+node scripts/e2e/attended-thinking-sync.mjs --step snapshot     --run $RUN --primary ios --ios http://<phone-ip>:8100 --mesh ios,android,macos
+node scripts/e2e/attended-thinking-sync.mjs --step run-normal   --run $RUN --primary ios --ios http://<phone-ip>:8100 --mesh ios,android,macos
+node scripts/e2e/attended-thinking-sync.mjs --step verify-normal --run $RUN --primary ios --ios http://<phone-ip>:8100 --mesh ios,android,macos
+```
+
+- `--mesh` narrows the run to devices that are genuinely available; excluded ones are printed.
+- `--step open-chat` re-opens an **existing** conversation. It fails on a fresh marker, which is
+  expected — `run-normal` is what creates the chat.
+- Keep the same `$RUN` across every step; the state file is keyed on it.
+
+## What was already fixed (do not redo)
+
+1. **`run-normal` now honours `--primary`.** It used to find the surface named `android` and dispatch
+   through Appium unconditionally, so `--primary ios` was accepted, validated, and then ignored —
+   the "iOS" run went out from the Android phone. `openNewAndroidChat` / `setAndroidThinking` are now
+   `openNewPrimaryChat` / `setPrimaryThinking`, named for the role, because they always spoke the
+   shared label vocabulary.
+2. **`--mesh` no longer lies.** It printed the exclusion and then ran every device anyway.
+3. **iOS quick-settings accessibility.** The popover's inner `TouchableWithoutFeedback` merged all
+   five rows into one element named `", Image Gen, Auto, , Thinking, ON, ..."`, so
+   `quick-thinking-toggle` did not exist as an addressable control. Fixed with `accessible={false}`.
+   This was a real VoiceOver defect, not only a test problem.
+
+## Known open problems — reproduce before theorising
+
+- **macOS `synced chat` times out at 90s.** In one observed case the very same conversation passed
+  when `verify-normal` was re-run immediately afterwards, and the conversation was visibly present
+  in the macOS sidebar with a completed reply. So the likely story is that macOS takes longer than
+  90s to surface a chat synced from iOS, not that it never does. **Confirm this before changing the
+  timeout** — if macOS really is that slow to show a synced conversation, the timeout is the symptom
+  and the latency is the bug.
+- **Windows did not receive an iOS-originated conversation at all**, while iOS, Android and macOS
+  all had it. Its Devices panel showed `7 nearby / 3 connected`, so it is on the mesh. Worth its own
+  investigation.
+- **`prepare-project` cannot stage files on iOS.** `stageProjectFixtures` throws for any non-Android
+  device: it uses `adb push` to put the fixture PDFs on the phone. The note in the code is accurate —
+  the UI journey is platform-agnostic, only file staging is not. iOS needs a real seeding path (the
+  app's Documents container via `devicectl`, or the Files app).
+
+## Device-driving facts that will otherwise cost you hours
+
+- **Appium and `adb shell uiautomator dump` cannot both own UiAutomator.** One instance exists on the
+  device, so an open Appium session makes every adb dump fail — and it reads as a wedged phone rather
+  than a driver collision. Hold the Appium session only around the steps that need it.
+- **Relaunch the app BEFORE walking back.** Pressing back until a screen appears walks straight out
+  to the launcher, where none of the app's screens exist and every further press is wasted.
+- **Start from a fresh chat.** A long transcript is unreadable to the dump.
+- **Put the run marker at the START of a prompt.** Peers find the conversation by its chat-list
+  preview, which truncates — a marker at the end of a long prompt never reaches them, and every
+  observer times out on a conversation that synced perfectly well.
+- **Background commands reset the working directory.** `cd` inside the backgrounded command itself.
+- **Never dump a whole page's text through CDP.** Query for the specific booleans or short strings
+  you need.
+
+## Still to build (requested, not started)
+
+- Multiple attachments in one turn — pdf + text + image on a single message. This is the **composer**
+  path, distinct from the project Knowledge Base path that `prepare-project` already covers.
+- A camera capture instead of a photo-library pick.
+
+## House rules
+
+- Read `rules.md` in full first — it is the single source of truth for this repo.
+- **Do not write tests unless explicitly asked.** The standard here is: finish the source change,
+  verify it by hand on the real device, and only then write tests when asked for them.
+- Evidence (screenshots, `result.json`, the action ndjson) lands under `.artifacts/e2e-flows/`.
+  Cite it when you report a result.

+# What to test by hand — `release/sync-feedback`
+
+Six defects were fixed, one is withdrawn (section 3), and the mobile inference runtime moved — which is the
+riskiest thing in here and has its own section. Each one below names the exact thing to do, what you should see, and what the
+failure looked like before, so a partial fix cannot pass as a whole one.
+
+Automated coverage already holds the logic: shared 461, mobile 3129, desktop pro sync 573, renderer 204.
+None of it can prove a real transfer between two machines, which is what this list is for.
+
+**Setup once:** Mac desktop and Windows desktop both running, Android and iPhone both paired, all four on
+the same network. Install the new mobile build on the phones and a fresh desktop build on both machines.
+
+---
+
+## 1. A received file can be opened — the one to test first
+
+Two reports were one defect, so both directions must pass.
+
+1. On the **phone**, send a file manually to **Windows**. Wait for the transfer to complete.
+2. On Windows, open Activity and find that row.
+
+- **Expect:** the row offers the file — a preview and a working Open.
+- **Before:** "This activity no longer has a local file", while the bytes were on disk.
+
+3. On the **phone**, attach an image to a chat message. Open that chat on the **Mac**.
+
+- **Expect:** the image opens.
+- **Before:** "the file has moved".
+
+**The case that actually broke it:** a device that has re-registered since the transfer. If you can, unpair
+and re-pair a phone, then open an activity row from *before* the re-pair. That is the condition the fix
+targets — the record names the peer as it was, the row asks for the peer as it is now.
+
+## 2. Generated media arrives on the phone
+
+Before this test, fully stop and restart the Windows `npm run dev` process so Electron reloads the
+new Shared bundle. Generated media and message attachments have no policy settings. They always move
+with their chat, so one successful replication to every connected device proves each journey.
+
+1. On the **desktop**, generate an image.
+2. Watch the **Android** phone.
+
+- **Expect:** it arrives with no extra switch touched. Generated media is on by default now.
+- **Before:** attachments arrived and generated media did not.
+
+3. Go to the phone's receiving settings. Confirm that **Chats**, **Projects**, **Model settings**,
+   **Generated media**, and **Message attachments** are not shown as options. These records always
+   sync across the mesh.
+
+   In the same screen, confirm there are only two sections: **Sending** and **Receiving**. Sending
+   must not show Chats, Projects, or Model settings, and there must be no Ambient sharing section.
+   Confirm that **Destination** and **From** each use one drop-down, not a row of device chips.
+   Confirm that **Automatic sharing** and **Receiving rules** are compact summary rows. Each
+   **Configure** action must open a policy matrix in a bottom sheet.
+   The Automatic sharing matrix must contain only **Screenshots** and **Downloads**. Generated media
+   and Message attachments move with their chats and must not have optional controls.
+
+4. Turn **Files** off. Generate another image.
+
+- **Expect:** it still arrives. "Files" means files sent to you directly, and it no longer governs
+  generated media.
+- **Before:** one switch silently governed both.
+
+Repeat 1 and 2 for a **message attachment** from desktop. It also has no Receiving switch and always
+syncs across the mesh.
+
+## 3. Copy in another app on Android, paste on the desktop
+
+The headline fix from your list, and the one that needs a permission you have never granted before.
+
+1. Install the new build. Open **Sync settings** and turn **Clipboard sync** ON.
+
+- **Expect:** a sheet appears saying Android hides the clipboard from apps that are not on screen, with a
+  button to open Accessibility settings.
+- **Expect:** nothing asked for this at launch — only when you switched the feature on.
+
+2. Tap the button, and turn **Off Grid AI** on in the Accessibility list.
+
+- Read that screen's description while you are there. It says what is read and what is not, and it is what
+  a user decides on.
+
+3. Come back to the app. Open **Chrome**, select some text, copy it.
+
+- **Expect:** it reaches the desktop clipboard.
+- **Before:** nothing outside the Off Grid app was ever captured — the phone had never sent one clipboard
+  entry, in either build.
+
+4. Copy something **inside** the Off Grid app.
+
+- **Expect:** still works. That path already worked and must not have regressed.
+
+5. Now turn the Accessibility service **off** in Android settings, return, and toggle Clipboard sync off
+   and on again.
+
+- **Expect:** the sheet appears again, because the grant is genuinely missing. It is not a one-time
+  explainer.
+
+6. Copy an image or a file in another app.
+
+- **Expect:** nothing syncs. Clipboard sync is text-only by design, so this is a check that it fails
+  quietly rather than doing something surprising.
+
+**The honest limit:** capture rides on a text selection. A long-press "Copy" with no highlight may still
+come back empty. If you find a copy that does not travel, tell me whether you had text selected.
+
+## 4. Pairing — NOT FIXED, but worth reproducing precisely
+
+I had this wrong and the test suite caught me. My first fix hid a cancelled attempt, and
+`deviceManagement.integration.test.tsx` disproved the premise: that journey cancels, reads "Pairing
+cancelled", retries and pairs, so retry-after-cancel already worked and the confirmation is wanted. I
+reverted the behaviour change and kept only a genuine robustness fix — an attempt is now read at its LAST
+state, so it can never be presented from an earlier row of its own history.
+
+**So do not test for a fix here. Test to pin down the sequence**, because the working journey and your
+report disagree, and the difference is the bug:
+
+1. Start pairing, type a **wrong** code, let it fail.
+2. Press **Cancel** on the failed attempt.
+3. Start pairing again with the correct code.
+
+Tell me exactly what the sheet says at each step, and whether the retry pairs. My suspicion is that a
+cancel does nothing to an attempt that has already reached `failed` — a terminal attempt has nothing left
+to cancel — so it stays on screen as the last thing that happened. The journey that passes cancels while
+still `waiting_for_confirmation`, which is a different state and a different code path.
+
+A screen recording of those three steps would settle it in one pass.
+
+## 5. A fresh phone can find the desktop
+
+This is the one that needs the awkward setup, and it is worth it — it silenced the desktop completely.
+
+1. On the **Mac**, plug in a **dock or USB-Ethernet adapter with no DHCP** — anything that lands on a
+   `169.254.x` self-assigned address. `ifconfig` should show it active with that address.
+2. From another machine: `dns-sd -B _offgrid._tcp local`
+
+- **Expect:** the Mac's record is listed.
+- **Before:** nothing from the Mac appeared, while its own setting still read discoverable. The log said
+  `Bonjour discovery unavailable: send EHOSTUNREACH 224.0.0.251:5353`.
+
+3. On a phone with **no pairing to that Mac**, open Devices and scan.
+
+- **Expect:** the Mac appears and can be paired.
+- **Before:** invisible. An already-paired phone kept working, which is what hid this.
+
+4. Now move the Mac between networks — switch Wi-Fi, or pull the cable and use Wi-Fi.
+
+- **Expect:** within a few seconds the Mac is discoverable again at its new address, with no restart.
+- **This is new behaviour.** Desktop never followed its own address before, so it is the most likely place
+  for a regression. Please try it twice.
+
+## 6. A generated image previews on Windows
+
+1. On **Windows**, generate an image.
+
+- **Expect:** the preview renders in the chat.
+- **Before:** the preview was broken; only Download produced a working file.
+
+2. Generate one whose prompt makes a long filename, and one while the app is at a different window size.
+
+- **Expect:** both preview. The old failure was in the path, not the picture, so a path with a space in it
+  is the interesting case — the profile directory "Off Grid AI Desktop" already contains two.
+
+3. Then confirm sync: that image should reach the phone (this is also test 2).
+
+## 7. Nothing regressed on macOS previews
+
+The preview fix touched a path shared by every locally served image.
+
+1. On the **Mac**, open Replay, a generated image, and a style-picker thumbnail.
+
+- **Expect:** all render as before. macOS never had the Windows fault, so this is purely a no-regression
+  check on the same code.
+
+## 8. The mobile inference runtime moved — the riskiest change here
+
+`llama.rn` went from 0.12.9 to 0.13.0-rc.0. It is a release candidate, and it changed the TTS API.
+
+1. Load a text model you use often and send a few messages.
+
+- **Expect:** loads and streams as before. Try one on the Hexagon/NPU backend too, since those kernels come
+  from this runtime — they are byte-identical to what we shipped, but worth one pass.
+
+2. **Speak a reply with OuteTTS.** This is the one I would test first.
+
+- **Expect:** speech sounds as it did.
+- **Why:** 0.13 removed the guide-token API OuteTTS used and moved that job into native. I adapted the
+  engine, but guide tokens are what kept the spoken output tied to the text, so a regression would show as
+  drifting or wrong words rather than an error.
+
+3. Try **Nemotron 3.5** — new in this runtime, and it should now load where it could not before.
+
+4. Voice mode: switch text → voice mid-conversation.
+
+- **Expect:** it may still say "LLM is busy". That is Pat's open defect, not this bump. Note if it got
+  worse.
+
+---
+
+## 9. The durable queue — a file that is still coming now says so
+
+The store that remembered finished transfers now remembers unfinished ones too. Read section 10
+before you start: half of what this changes is deliberately not wired yet, and testing for it would
+waste your time.
+
+**The one line that was the bug:** the store accepted only `completed` and `failed` and returned
+early on everything else. So "queued for a device that is switched off" existed in memory and nowhere
+else, and closing the app erased the fact that anything was expected at all.
+
+### 9.1 A file still on its way survives a restart
+
+1. Put the **Windows** desktop to sleep, or quit it.
+2. From the **phone**, send it a file.
+3. Look at Activity on the phone.
+
+- **Expect:** a row for that file, reading as queued, naming Windows.
+- **Before:** it appeared briefly and then nothing. Not an error, just silence.
+
+4. **Force-quit the phone app and reopen it.** Open Activity.
+
+- **Expect:** the row is still there, still queued. This is the whole point.
+- **Before:** gone. Nothing recorded that a file was owed.
+
+5. Do the same in reverse: desktop to a phone in aeroplane mode, then restart the desktop app.
+
+### 9.2 An arriving file draws a real placeholder
+
+The control naming a file arrives before its bytes, so the receiver can show what is coming.
+
+1. Send a **large** image or PDF phone → Mac, so the bytes take a moment.
+2. Watch Activity on the Mac while it transfers.
+
+- **Expect:** a row with the correct **filename and size** while it is still arriving, and a bar that
+  fills. Not a spinner over nothing, and not a row that appears only once it has landed.
+- **Before:** nothing until it completed.
+
+### 9.3 Activity lists file transfers only
+
+Everything rides one queue now, but Activity is the list for things whose bytes you are waiting on.
+
+1. With Clipboard sync on, copy some text. Send a chat. Change a model setting. Add a document to a
+   project.
+2. Open Activity on both devices.
+
+- **Expect:** **none** of those four appears as an Activity row. Files, generated media, message
+  attachments, screenshots, downloads and models do.
+- **Why it matters:** a row per clipboard entry or per chat op would bury the transfers.
+
+Then confirm they still actually sync — hidden from Activity is not the same as off.
+
+### 9.4 History did not regress
+
+The same store holds the finished rows it always did.
+
+1. Open Activity on a device with a transfer history.
+
+- **Expect:** completed and failed rows as before, newest first, with the same names and devices.
+- **The case worth checking:** send a **multi-file model package**. Its rows finish inside the same
+  millisecond, and the ordering had to be given a deliberate tie-break. They should read in a stable
+  order, and re-opening the screen must not shuffle them.
+
+### 9.5 A queued row is never tidied away
+
+History is capped at 100 rows. That cap must not eat work that has not happened yet.
+
+1. On a device with a long transfer history, queue a file for a peer that is off.
+2. Move enough files to push the finished count past the cap.
+
+- **Expect:** the queued row is still there. Only finished rows are forgotten.
+
+### 9.6 Retry and cancel do what the row offers
+
+The two platforms genuinely differ here, and it is now declared rather than accidental.
+
+1. Make a transfer fail (peer off mid-send).
+2. On the **desktop** row: **Retry** is offered, and pressing it re-sends.
+3. On the **phone** row: retry is **not** offered for a live transfer; cancel and dismiss are.
+
+- **Expect:** no button that does nothing when pressed.
+- **Before:** the phone briefly offered a retry that reached no handler and threw.
+
+### 9.7 Projects still sync, quietly
+
+1. Add a document to a project on one device.
+
+- **Expect:** it reaches the other device, and creates **no** Activity row.
+
+---
+
+## 10. What is NOT wired yet — do not report these as bugs
+
+The queue records what is owed. It does not yet act on it. Three consequences:
+
+- **A queued row does not resend itself.** After 9.1, bringing the device back does **not** make the
+  file go automatically from the restored row. Retry still runs from memory, so a restart loses the
+  ability to resume even though the row survives. Replaying from rows is the next change, and it is
+  the one that needs its own device round.
+- **Models and clipboard still keep their own separate stores.** They were already durable, so
+  nothing regresses, but they are not on the one queue yet. Collapsing them needs the row to carry
+  package identity first — a model package is one row over several transfers.
+- **Some rows are still assembled by the screen.** Ambient deliveries on desktop, and ambient,
+  knowledge and model rows on mobile, are still built in the UI. They work; they are simply not
+  through the shared projection yet.
+
+### Test status, stated honestly
+
+- **shared** `@offgrid/sync` — 466/466.
+- **desktop** — 4144 passed, 1 skipped, 0 failed across 437 files. The separate `.dbtest` project is
+  262/264; both failures are `fetch failed` in `image-runtime-reliability`, an external-network test
+  unrelated to this work.
+- **mobile** — 8190 passed, 103 failed across 11 suites. **None of the failures is sync.** They are
+  rntl screen suites failing at import with `Cannot read properties of undefined (reading
+  'CenteredAlert')` from a barrel cycle in `src/components/index.ts` via `ModelCardContent.tsx` —
+  separate in-flight work. Every sync suite passes, including `ambientShare.integration`.
+
+---
+
+## Not fixed, so do not test for a fix
+
+Recorded in `FEEDBACK_2026-08-12.md` with the reason each one waits:
+
+- **A reinstall costs a mesh seat** (Pat). Needs a device identity that survives reinstall — a product
+  decision, and acting without one would evict a device someone still uses.
+- **"LLM is busy" on a text-to-voice switch** (Pat). Cause found: the send is refused after a 15-second
+  wait while this codebase documents a 74-second prefill. The fix should wait on progress rather than
+  elapsed time, and wants a device round of its own.
+- **Muse Glimmer 30B on Android.** Still absent from llama.rn 0.13.0-rc.0. Upstream PR #379 carries it and
+  is open; we check again immediately before the release. It IS testable on **desktop**, which moved to
+  llama.cpp b10369 — and by Meta's own numbers it is a desktop model anyway: under 20 GB at 4-bit, needing
+  a 24-32 GB envelope.
+- **The persona text opening a reply.** The route is real — `systemPrompt` is a synced setting and that
+  sentence exists only in mobile — but the evidence was overwritten before it could be read. If you see it
+  again, run the query in the feedback doc **before** changing any setting.
+- **The web-search result reading as the answer.** Did not reproduce; that chip renders collapsed. A
+  screenshot of the turn would settle it.
+
+---
+
+# Added 2026-08-12 (later) — vision repair, the loader, and the desktop chat path
+
+These landed after the sections above. The vision ones matter most: they were found on a real iPhone
+holding a model that arrived from Android, and that exact path is what section A reproduces.
+
+## A. A transferred vision model can be repaired from the chat
+
+The case: SmolVLM on iOS, sent from Android with `Send model`, carrying its vision tag but refusing
+photo attachments — and the Download Manager's repair answered with a raw **401**.
+
+1. On **Android**, pick a vision model whose projector is present. Send it to the **iPhone**.
+2. On the iPhone, make that model active and open a chat.
+
+- **Expect:** if the package arrived whole, photos attach and no card appears. That is a pass.
+- **Before:** the model advertised vision and the composer refused the photo, with nothing on screen
+  explaining why.
+
+3. To reach the repair path, use a model whose projector is genuinely absent (an older transfer, or a
+   `recovered_` row). Open a chat with it active.
+
+- **Expect:** a card — **"This model can't see images"** — with **Get vision file**.
+- **Expect:** tapping it shows the three dots, then either fetches the file or explains why it cannot.
+- **Before:** no route from the chat at all; the fix lived in a screen the user had no reason to open.
+
+4. Tap **Get vision file** and wait.
+
+- **Expect on success:** the model reloads and photos attach.
+- **Expect when the source is unknown** (a locally imported model): *"No Source To Repair From"* naming
+  the next step. This is a PASS — an imported model has no upstream, and saying so is correct.
+- **Expect when several repos match:** *"Cannot Identify This Model"*, listing them. Also a PASS: a
+  projector from a different quantisation loads and then reads images wrongly, so refusing is right.
+- **Before:** every one of these was `Repair Failed: 401`.
+
+**Check the same outcomes in the Download Manager** (the wrench on a completed row). Both surfaces read
+one message rule, so they must say exactly the same thing for the same model.
+
+## B. A model stops advertising sight it does not have
+
+1. Find a vision model with no projector on the device. Open the **model picker** (home sheet) and the
+   **model selector** in chat.
+
+- **Expect:** no "Vision" badge on that row.
+- **Before:** the badge showed from a stored flag while the composer refused images — the two disagreed
+  about the same model, which is what made this look like a chat bug.
+
+## C. The three-dot loader replaced every spinner
+
+One loader now means one thing. A ring spinner on a button reads as a retry glyph, which is why pairing
+and sharing looked like they had failed the moment they started.
+
+1. **Pair** a device — watch the Pair button.
+2. **Share a file** — watch the Share button.
+3. Trigger the icon-button pending states on the Devices screen: **reconnect**, **disconnect**.
+4. Open **Integrations** and connect an MCP server.
+5. Open the **model transfer sheet** while it loads, and an **audio** message while it prepares.
+
+- **Expect:** three pulsing dots everywhere, never a rotating ring.
+- **Expect:** a button does **not** change height when it flips to loading.
+- **Before:** a circular spinner that read as "retry".
+
+## D. Desktop — an attached image survives Resend, Regenerate and Edit
+
+This is the one that produced *"I don't see an image attached"* on a message that visibly had one.
+
+1. Attach an image in desktop chat with a vision model active. Send it. Confirm the answer describes the
+   image.
+2. On that same turn press **Regenerate**.
+3. Press **Resend** on the user message.
+4. **Edit** the user message text and submit.
+
+- **Expect:** all three still see the image. The attachment chip stays on the turn after an edit.
+- **Before:** each replayed the text alone; the model said it saw no image and fell back to reading your
+  screen. Editing also deleted the attachment permanently, so the chip vanished from the thread.
+
+5. Reopen the conversation after an edit.
+
+- **Expect:** the chip is still on the edited turn.
+
+## E. Desktop — the thinking toggle on a non-Qwen model
+
+1. Load **Muse Glimmer 30B** on desktop. Turn **Thinking** on and send a prompt.
+2. Turn it off and send another.
+
+- **Expect:** the two replies differ in whether reasoning is produced.
+- **Before:** the toggle did nothing in either direction — we sent `enable_thinking`, which that template
+  never reads, plus a `<think>` parser for delimiters it never emits.
+
+**Report the off position specifically.** ON is safe (the template defaults to high), but the OFF value
+is the one unverified thing in this change — I could not re-read the template to confirm how it renders a
+disable. If OFF still reasons, say so; that is a known gap, not a surprise.
+
+## F. Desktop — sizes agree on one card
+
+1. Start downloading a large model (Nemotron 3.5 is 25.4 GB).
+
+- **Expect:** the size in the meta line and the size in the progress line are the **same number**.
+- **Before:** "25.4GB" above "1.2 GB of 23.7 GB" — decimal GB against GiB, both labelled GB.
+
+## G. Desktop — the two new models, and the sidebar
+
+1. Restart the desktop app. Open **Models**.
+
+- **Expect:** **Nemotron 3.5 Lightning 30B** under Text, **Muse Glimmer 30B** under **Vision** (it has a
+  projector, so it is promoted), each with a **NEW** badge and a **CHALLENGER** chip.
+- **Note:** a restart is required — the catalog loads in the main process.
+
+2. Switch the app to **light** theme and hover each sidebar row.
+
+- **Expect:** the label darkens and stays readable.
+- **Before:** the label turned near-white on a near-white row and disappeared. Light mode only.
+
+## H. The four-device mesh connects every direct pair
+
+Use Android, iPhone, Mac and Windows on the same Wi-Fi network.
+
+1. Start Sync on all four devices. On each device, press **Rescan** once.
+2. Wait for the mesh to settle. Do not enter another pairing code.
+
+- **Expect:** each device connects directly to the other three devices.
+- **Expect:** Android shows only **WiFi**, never **Nearby**.
+- **Expect:** every LAN route is named **WiFi**.
+
+3. Force-quit Android and iPhone. Start both apps at nearly the same time.
+
+- **Expect:** Android and iPhone connect to each other automatically.
+- **Expect:** simultaneous silent pairing does not leave both phones disconnected.
+
+4. While the iPhone is on the network, make its saved pairing need repair.
+
+- **Expect:** the iPhone stays under **Available** because it is reachable now.
+- **Expect:** the key action is visible, and no pencil is visible.
+- **Expect:** after the iPhone leaves the network and discovery reports it lost, the row moves to
+  **Saved**.
+
+5. Use the key action on an offline saved row and enter the current code.
+
+- **Expect:** the pairing is replaced, the device reconnects, and the licence still uses the same
+  number of device slots.
+
+## I. Enhanced prompt and generated image use one Mobile result
+
+1. Generate an image on Android with prompt enhancement on.
+
+- **Expect:** **Enhanced prompt** is collapsible at the top of the image result.
+- **Expect:** the image and caption are below it in the same message bubble.
+- **Expect:** the result has one timestamp, one menu and no empty bubble.
+
+2. Confirm the image reaches iPhone, Mac and Windows and appears in each Gallery.
+3. Restart one receiving device.
+
+- **Expect:** the image remains in the chat and Gallery after restart.
+
+## J. A phone attachment reaches another phone
+
+1. With no older transfers queued, attach one image to a chat on iPhone.
+2. Watch the same chat on Android.
+
+- **Expect:** a loader appears when the durable record arrives.
+- **Expect:** the image replaces the loader without a rescan or pairing code.
+
+3. Repeat while a large iPhone-to-Android file is already moving.
+
+- **Expect:** the loader can remain while the older file is ahead in the queue, but the image must
+  arrive when its bytes are transferred. It must not disappear or become an empty message.

+# Model memory & residency — test matrix
+
+What is covered, what is NOT, in one place. Scope: everything that decides whether a model loads,
+co-resides, is evicted, or is refused — text, image, STT, TTS, embedding, classifier.
+
+Source of truth for "covered": a test in `__tests__/integration/` that drives the real stack over
+device-boundary fakes and asserts on a rendered surface. Unit tests of the planner are deliberately
+NOT counted as coverage here.
+
+Counts as of 16 Aug 2026: **28 integration tests** in `__tests__/integration/memory/`.
+
+---
+
+## 1. Lifecycle, per model type
+
+| Capability | text | image | STT (whisper) | TTS | embedding | classifier |
+|---|---|---|---|---|---|---|
+| Loads when it fits | ✅ `litertLazyOnSelect`, `pickerRamMatchesResidencyChip` | ✅ `imageMemoryCard.guard` | ✅ `whisperResidentOnDownload` | ✅ `ttsCoresidentInVoiceTurn` | ❌ | ❌ |
+| Refused gracefully when it does not fit | ✅ `loadAnywayCardRendered` | ✅ `imageMemoryCard.guard` | ✅ `whisperBlockedFreeRetry` | ❌ | ❌ | ❌ |
+| Override ("Load Anyway") | ✅ `overrideFloor`, `loadAnywayCardRendered` | ✅ `imageMemoryCard.guard` | ❌ | ❌ | ❌ | ❌ |
+| Ejected by the user | ✅ `modelSelectorEjectResident`, `lazyReloadAfterEject` | ⚠️ via `ejectAllUnloadsEveryType` only | ✅ `ejectAllLeavesWhisper` | ⚠️ via eject-all only | ❌ | ❌ |
+| Lazy-reloads after eject | ✅ `lazyReloadAfterEject` | ❌ | ❌ | ❌ | ❌ | ❌ |
+| Reclaimed when memory is tight | ✅ `textPreloadGateReclaimAware` | ❌ | ✅ `sttReclaimedOnSend`, `voiceNoteReclaimsStt` | ✅ `memoryWarningEvictsSidecars` | ❌ | ❌ |
+
+## 2. Co-residency pairs
+
+| Pair | Covered |
+|---|---|
+| text + STT | ✅ `textWhisperCoresident` (T116) |
+| text + TTS | ✅ `ttsCoresidentInVoiceTurn` (T120) |
+| text + image | ✅ `resendAfterImageGen` (M11) — clean text pages in around dirty image |
+| text + LiteRT text (swap, never both) | ✅ `residencySwap.happy` |
+| image + STT | ⚠️ present in the same files but not the asserted subject |
+| image + TTS | ❌ |
+| STT + TTS (a full voice turn) | ⚠️ `ttsCoresidentInVoiceTurn` covers TTS; the pair is not the subject |
+| anything + embedding | ❌ **not covered at all** |
+| anything + classifier | ❌ **not covered at all** |
+| three heavy at once | ❌ |
+
+## 3. Eviction
+
+| Trigger | Covered |
+|---|---|
+| OS memory-warning evicts sidecars, keeps active heavy | ✅ `memoryWarningEvictsSidecars` (T117) |
+| Loading a heavy model evicts another heavy | ✅ `residencySwap.happy`, `residencyMatrix.modes` |
+| Eject All frees every type | ✅ `ejectAllUnloadsEveryType`, `ejectAllLeavesWhisper` |
+| Policy change ejects residents | ✅ `policyChangeEjectsResidents` |
+| A failed unload is not counted as freed | ✅ `failedUnloadOverCommits`, `sttReclaimFailedUnload` |
+| Eviction ordering across all 3 modes | ✅ `residencyMatrix.modes` (scenario-as-data) |
+| The model mid-generation is never evicted | ❌ |
+| TTS not evicted while speech is playing | ❌ (`canEvict` exists in code, untested) |
+| Embedding not evicted mid-RAG | ❌ |
+
+## 4. The estimate itself
+
+| Question | Covered |
+|---|---|
+| Advisory check and load gate size the SAME model | ✅ `imageEstimatorDivergence` (Q14) — **image only** |
+| Same, for TEXT (`modelPreloader` 1.5x vs `activeModelService` 2.2x) | ❌ **not covered — and they currently disagree** |
+| Pre-load gate reads the same reclaim-aware RAM as the loader | ✅ `textPreloadGateReclaimAware` |
+| **Context length changes whether a model fits** | ❌ **not covered anywhere** — no test mentions contextLength / n_ctx |
+| Predicted cost matches actual footprint after load | ❌ (needs a device) |
+| KV cache quantisation changes the requirement | ❌ |
+| Estimate is right for a vision model (mmproj added) | ❌ |
+
+## 5. Policy modes
+
+| Case | Covered |
+|---|---|
+| Balanced co-residency | ✅ `residencyMatrix.modes`, `loadingModes` |
+| Aggressive commits more RAM | ✅ `aggressiveDirtyOverCommit` (M6) |
+| Lean/conservative | ✅ `loadingModes`, `residencyMatrix.modes` |
+| Switching mode with residents loaded | ✅ `policyChangeEjectsResidents` |
+| "Aggressive would fit this" recommendation | ❌ **feature does not exist** |
+
+## 6. What the user is told
+
+| Case | Covered |
+|---|---|
+| Refusal shows a card, not a crash | ✅ `imageMemoryCard.guard`, `loadAnywayCardRendered` |
+| RAM shown agrees across surfaces | ✅ `pickerRamMatchesResidencyChip`, `modelSelectorShowsLoadedRam` |
+| Over-budget-but-warnable model warns | ✅ `curatedLiteRTOverBudgetWarning` |
+| The refusal NAMES the numbers (needs X, device has Y) | ❌ **feature does not exist** |
+| The refusal offers a way out (lower context / smaller model) | ❌ **feature does not exist** |
+| A silent preload failure is surfaced | ❌ **`modelPreloader` returns bare — no signal at all** |
+| Eviction is visible to the user | ⚠️ implied by the selector tests, never the subject |
+| Download screen shows total (not available) memory | ❌ (changed 16 Aug, untested) |
+
+## 7. Axes that are thin or absent
+
+| Axis | State |
+|---|---|
+| Platform | android 25 files / ios 6 — **iOS is the jetsam platform and is the thinner half** |
+| Engine | litert appears in 12 of 28; llama/gguf is the default elsewhere |
+| Relaunch / restart | n/a **by design** — nothing is resident after a relaunch, so there is no state to cover |
+| Backend (CPU vs GPU/NPU) | ❌ nothing pins that the backend changes the estimate |
+| Device tier (4 / 8 / 12 / 24 GB) | partially, via seeded RAM in individual tests; not a named axis |
+| Cross-device (a peer pushing settings this device cannot honour) | ❌ |
+
+---
+
+## The shortlist — genuinely uncovered, testable today, no new feature needed
+
+1. **Context length decides the fit.** The Qwythos case: refused at a large context, loads at a small
+   one. Zero tests mention context length, and the current estimator cannot express it.
+2. **Text advisory vs authoritative estimate agreement.** `imageEstimatorDivergence` pins exactly this
+   for image; the text path has the same divergence (1.5x vs 2.2x) and no test.
+3. **The embedding model as a resident** — it registers and takes `runExclusive`, and nothing covers it.
+4. **The classifier swap** — the tool-routing model swapping the text model out and back mid-turn.
+5. **The active model is never evicted mid-generation**, and TTS is not evicted mid-playback.
+
+## Blocked on a feature that does not exist yet
+
+- A refusal that names its numbers
+- A recommendation to lower context, switch policy, or free memory
+- Any signal at all from a failed background preload

+# Brief for the next agent — Off Grid, open concerns
+
+You are picking up work in `/Users/user/wednesday/off-grid-ai`, a workspace of five separate git
+repos: `desktop` (OGAD), `mobile` (OGAM), `sync` (OGAS), `shared` (the `@offgrid/*` packages) and
+`website`. `desktop`, `mobile` and `shared` are all on branch `release/sync-feedback`.
+
+Read `mobile/rules.md` in full before touching that repo. For device E2E work, read
+`mobile/docs/IOS_E2E_HANDOFF.md` — it has the device table, WebDriverAgent bring-up and the
+device-driving traps, and is not repeated here.
+
+## Ground rules
+
+- **Never reset, stash, revert, force-push or delete anything.** Every repo holds unrelated
+  in-progress work. Commit only files you changed yourself.
+- **Do not write tests unless explicitly asked.** The standard is: finish the source change, have it
+  verified by hand on a real device, and write tests only when asked. A test written against
+  unverified behaviour encodes the bug.
+- **Report status as a gate — code / wired / verified.** A premature "done" is a defect. If you did
+  not watch it work, say so.
+- Verify on the real surfaces. Typecheck and unit tests do not catch build, route or device errors.
+
+## Background
+
+Three read-only research agents compared the released tag `v0.0.103` (2026-07-16) against
+`release/sync-feedback` (554 commits, 874 files). Everything below is their evidence, unverified on
+device. **Nothing in this list has been reproduced on hardware yet — your first job on any item is to
+confirm it is real before fixing it.**
+
+Note `pro/` is a git submodule in both `mobile` and `desktop`; the Pro sync implementation is NOT in
+that 874-file diff, only a pointer move (`ff0d8742` → `8883ae51`).
+
+---
+
+## Priority 1 — memory and crash risk (worst on iOS)
+
+Two protections the user cares about most were checked and are **intact**; do not "fix" them:
+- Android memory-reclaim credit — `mobile/src/services/memoryBudget.ts:86-95`, zero commits since the tag.
+- iOS jetsam guard refusing a clean sidecar on a dirty image — `mobile/src/services/modelResidency/index.ts:197-236`.
+
+What WAS removed, in commits `2fa3b967` and `43f520a0` (both 2026-08-15):
+
+1. **`getMaxContextForDevice` deleted** — the RAM-tier `n_ctx` ceiling (≤6GB→2048, ≤8GB→4096,
+   else 8192), along with its 7 unit tests. `llm.ts` now reads *"Do not impose a second RAM-tier
+   ceiling here."* On iOS a memory breach is an **uncatchable jetsam SIGKILL**, so the engine's
+   GPU→CPU→CPU@2048 fallback ladder cannot catch it. The deleted comment cited real evidence:
+   *2098MB on a 4GB iPhone 12, mid-generation*.
+2. **`n_predict` app-owned ceiling deleted** — this REVERTS an Aug-13 fix (`58581c7c`) that added
+   `CONTEXT_OUTPUT_BUDGET_RATIO = 0.40` for *"a requested output equal to the full context leaves
+   zero prompt space and llama.cpp rejects the turn"*. Now `mobile/src/services/llmHelpers.ts:419-422`
+   passes `n_predict: requestedMaxTokens` raw.
+3. **8192 max-tokens cap and the LiteRT RAM-tier ceiling deleted.**
+
+And simultaneously these became **writable by a paired desktop** — `contextLength`, `maxTokens`,
+`gpuLayers`, `nThreads`, `nBatch`, `kvCacheType`, `flashAttn` — validated for type and range only,
+with **no device-fit check**: `mobile/src/services/sync/mutation.ts:55-113` →
+`mobile/pro/sync/mobileStateMaterializer.ts:73-77` → `mobile/src/stores/appStore.ts:310-324`.
+
+**The sharpest instance.** The `maxTokens ≤ contextLength` invariant is enforced ONLY in the UI hook's
+`onChange` (`mobile/src/hooks/useTextGenerationSettings.ts:99,104-107`). The sync path writes the
+store directly and bypasses it. Desktop offers maxTokens up to 32768 and ctxSize up to 131072, and the
+mutations are per-key — so a desktop-side maxTokens change alone lands on a phone still at 4096,
+giving `n_predict 32768 > n_ctx 4096`: llama.cpp rejects the turn before inference, while the settings
+screen still displays "4096". A silent UI/engine divergence.
+
+There is in-repo precedent for this failure class: `mobile/src/stores/appStoreMigrations.ts:30-33`
+documents a removed MCP auto-boost that pinned context to 32768 and *"never restored it, causing OOM
+crashes and tanked tok/s on flagship devices"*, needing a one-time repair migration. Sync can now
+reproduce that state from a peer, with no migration to undo it.
+
+**Suggested direction (confirm before building):** the clamp belongs at the store boundary, not the
+UI, so every writer — local and synced — passes through it. Also consider whether a synced value
+should be capped to what the receiving device can actually fit.
+
+**Device tests that settle it:**
+- 4GB iPhone (12 / SE3), small GGUF, set Context Length to the model's max, send a long prompt.
+  Old builds capped to 2048. Fear: hard termination, no JS error, no crash dialog.
+- Pair a 4GB iPhone with desktop, set desktop Context window to 131072, watch what mobile becomes.
+- Mobile Context 4096 + desktop Max output 32768 → send. Expect "Not enough context space", and a
+  settings screen still reading 4096.
+- Regression checks the fix must NOT break: 12GB Android, Aggressive, load the largest GGUF that used
+  to load — expect it to load. iOS: generate an image, then trigger a whisper/TTS sidecar mid-render —
+  expect an overridable refusal card, NOT a jetsam kill.
+
+---
+
+## Priority 2 — cross-device voice arrives broken
+
+Phone→Mac audio-attachment sync is **newly enabled** in this delta and is half-built.
+
+- The Mac classifies any non-image attachment as text:
+  `desktop/pro/main/sync/shared-file-sync-service.ts:1236` —
+  `kind: control.mimeType.startsWith('image/') ? 'image' : 'text'`.
+  A `.wav` therefore renders through the generic file-chip branch
+  (`desktop/src/renderer/src/components/MemoryChat.tsx:770-795`) as a paperclip, the filename, and the
+  literal word **"text"**. No player, no duration.
+- Clicking it opens a **blank** modal: `openAttachment`
+  (`MemoryChat.tsx:4054-4067`) routes non-images to a text viewer, and the materializer wrote
+  `text: ''`. The `<pre>` at `MemoryChat.tsx:5648-5656` renders nothing. Download is the only way to
+  hear the audio.
+- **Duration and audio format are carried and then dropped.** The descriptor has them
+  (`shared/packages/sync/src/transfer/shared-file.ts:44-56`); the writer at
+  `shared-file-sync-service.ts:1233-1243` writes neither.
+- The transfer is **always-on and invisible** — `send: "always"`, `receive: "always"`,
+  `activity: "hidden"` in `shared/packages/sync/src/sync-sharing-catalog.ts:32-39`. No opt-in, and no
+  visible row if it stalls.
+- A silent voice note (STT yields nothing) still sends — `mobile/src/components/ChatInput/voiceNoteSend.ts:119-124` —
+  producing an empty user bubble plus the chip.
+- Mac→phone audio is simply not implemented (desktop only publishes generated images). That is an
+  asymmetry, not a bug.
+
+Confirmed NOT a problem: TTS voice is not syncable on either side.
+
+**Test:** record a voice note on the phone in Voice/Audio mode; on the Mac expect the transcript as
+message text and a chip reading `<name>.wav  text`; click it and expect a blank viewer.
+
+---
+
+## Priority 3 — things that could break everything, unverifiable by reading
+
+- **`llama.rn` bumped `^0.12.5` → `0.13.0-rc.0`** (a release candidate) in `mobile/package.json`.
+  Every test fakes the native module, so nothing catches this. If it is bad, replies fail everywhere
+  and voice merely *looks* broken. **Test first: send one typed message on a real iPhone and a real
+  Android.**
+- **A new Pro admission gate can withhold the entire audio bundle.**
+  `mobile/src/bootstrap/loadProFeatures.ts` computes `admitted` and returns before `pro.activate()`
+  when false; all audio lives in `activateAudio()` inside `activate()`. Symptom: the Voice
+  quick-settings row is gone and nothing is ever spoken. The rule only denies on a positive
+  "inactive", so cold/offline start is safe — but `proEntitlementLifecycle.start()` is new at boot.
+  No test asserts that `'inactive'` withholds audio while `'unknown'` grants it.
+- **STT model detection changed** — `mobile/src/stores/whisperStore.ts:227` now lists downloaded
+  models, applying a 10 MB floor (`whisperModelFiles.ts:58`) and deriving the id from the filename.
+  Symptom: the mic shows the download prompt although the model is on disk.
+
+---
+
+## Priority 4 — behaviour changes worth a decision
+
+- **Tool step limit 3/5 → configurable, default 25** (`mobile/src/stores/appStore.ts:207`). At the cap
+  it no longer forces a final answer: it discards streamed content and emits a notice
+  (`generationToolLoop.ts:1130-1141`). `forceFinalTextResponse` was deleted. Because `maxToolCalls`
+  is synced, a peer set to `1` turns any single-tool request into that notice. 25 rounds of on-device
+  tool calls is also ~8× the old ceiling — a latency and context-growth exposure the old cap hid.
+- **Model resolution falls back to filename** when the id misses
+  (`mobile/src/services/activeModelService/resolveModel.ts:24-40`). Deliberate — it fixed a "live
+  model, refused send" bug — but two models sharing a GGUF filename now resolve to whichever is first.
+  `resolveDownloadedModel` and `selectedTextModelIdOf` have **no test files at all**.
+- Unchanged and safe, so do not re-audit: the image-vs-text decision function, the intent classifier,
+  the auto/force/disabled badge cycle, tool-schema selection, and the `<|think|>` prepend.
+
+---
+
+## Priority 5 — mesh defects seen live tonight
+
+- **macOS takes longer than 90s to surface a chat synced from iOS.** In one run the same conversation
+  passed when `verify-normal` was re-run immediately after, and it was visibly in the macOS sidebar
+  with a completed reply. **Do not just raise the timeout** — if macOS really is that slow, the
+  latency is the bug and the timeout is the symptom.
+- **Windows never received an iOS-originated conversation at all**, while iOS, Android and macOS all
+  had it. Its Devices panel read `7 nearby / 3 connected`, so it is on the mesh. Unexplained.
+
+## Machine state as of this handoff
+
+- **iPhone** — WebDriverAgent up. It serves on the phone's own IP; read it from the launcher log. The
+  launcher process IS the server, and after any WDA restart you must create a session before the
+  rig's `attach()` works. See the E2E handoff doc.
+- **macOS** — up on CDP `127.0.0.1:9222`.
+- **Windows — BROKEN, unresolved.** The app restarts fine (4 electron processes) and
+  `Test-NetConnection 127.0.0.1:9224` reports open, but nothing serves HTTP on 9224 — not through the
+  SSH tunnel and not from the box itself (`Invoke-WebRequest` fails locally). The documented start is
+  `npm run dev -- --remoteDebuggingPort 9224` from `C:\Users\oga\ogad-git` (see
+  `mobile/scripts/e2e/GENERATED_IMAGE_SYNC.md`); the originally-working process had the Chromium form
+  `electron . --remote-debugging-port=9224` on its command line. Reach the box with
+  `ssh oga@192.168.1.26`; the tunnel is
+  `ssh -N -L 9224:127.0.0.1:9224 oga@192.168.1.26`. **Suspect `Test-NetConnection` is a false
+  positive and the flag never reaches Chromium.**
+- **Android** — dropped off `adb` entirely (`adb devices` empty after a server restart). Needs a
+  physical reconnect before any mesh run can include it.
+
+## Already done this session — do not redo
+
+- `run-normal` in `attended-thinking-sync.mjs` now honours `--primary`; it previously found the
+  surface named `android` and dispatched through Appium regardless, so every "iOS" run went out from
+  the Android phone.
+- A `--mesh` flag that genuinely excludes unavailable devices (it used to print the exclusion and run
+  them anyway).
+- iOS quick-settings accessibility: the popover merged all five rows into one element, so
+  `quick-thinking-toggle` did not exist as a control. Fixed with `accessible={false}`; verified on
+  device. This was a real VoiceOver defect.
+- Desktop attachment images now fill their bubble and crop (WhatsApp-style), with the bubble capped to
+  a column.
+- Each desktop is now resolved against several addresses (macOS `127.0.0.1`/`.25`/`.64`, Windows
+  `127.0.0.1`/`.94`/`.26`), first to answer wins.
+
+## Still to build (requested, not started)
+
+- An E2E for multiple attachments in one turn — pdf + text + image on a single message. This is the
+  **composer** path, distinct from the project Knowledge Base path already covered by
+  `prepare-project`.
+- An E2E using camera capture instead of a photo-library pick.
+- iOS file staging for `prepare-project`: `stageProjectFixtures` throws for any non-Android device
+  because it uses `adb push`. The UI journey is already platform-agnostic; only staging is not. iOS
+  needs a real path (the app's Documents container via `devicectl`, or the Files app).
+- `generated-image-sync`, `vision-image-sync` and `vision-answer-sync` are still Android-hardcoded and
+  need the same `--primary` treatment `run-normal` received.

+# Sync Feedback Release Repair Plan
+
+Date: 2026-08-13  
+Status: In progress  
+Source acceptance plan: [MANUAL_TEST_2026-08-12.md](./MANUAL_TEST_2026-08-12.md)
+
+## Objective
+
+Repair the release branches against `main`, remove the known failure paths, and verify the complete
+Desktop and Mobile journeys. Work is sequential. A later phase does not start until the prior phase
+has a green focused gate.
+
+The release repositories are:
+
+- `shared`
+- `desktop/pro`
+- `desktop`
+- `mobile/pro`
+- `mobile`
+
+Top-level `sync` is separate EasyShare work. `website` has no tracked release delta. Neither is part
+of this release train.
+
+## Completion language
+
+Each item has three independent states:
+
+- **Code**: the implementation exists.
+- **Wired**: every consumer uses the canonical owner and the replaced path is gone.
+- **Verified**: automated gates and the real user journey pass.
+
+An item is complete only when all three states are true.
+
+## Engineering rules
+
+1. Give each fact, identity, rule, state machine, and resource one canonical owner.
+2. Make UI and host representations read-only projections of that owner.
+3. Keep business rules in services and pure shared policy. UI sends intent only.
+4. Depend on typed contracts at filesystem, native, persistence, network, and model boundaries.
+5. Reuse an existing abstraction when it is the correct owner. Do not add parallel helpers.
+6. Remove the replaced path after migration. Compatibility aliases can exist only at input
+   boundaries.
+7. Fake only uncontrollable external boundaries. Do not mock Off Grid services, stores, hooks, or
+   components.
+8. Land one coherent, green commit per owning seam. Do not mix unrelated fixes.
+9. Use merge commits. Do not squash.
+10. Record evidence in this document after every completed gate.
+
+## Canonical owners
+
+| Fact                                          | Canonical owner                        |
+| --------------------------------------------- | -------------------------------------- |
+| File existence and metadata                   | Mobile filesystem adapter              |
+| Receive categories and legacy aliases         | `@offgrid/sync` receive policy         |
+| Transfer state, visibility, and actions       | `@offgrid/sync` transfer service       |
+| Persisted transfer order                      | Transfer-history contract              |
+| Device actions                                | Shared device-capability projection    |
+| Model origin                                  | Validated transfer manifest            |
+| Current network endpoint                      | Desktop discovery service              |
+| Pending chat attachments                      | Desktop shared-file service            |
+| Chat edit and regeneration                    | Desktop conversation service           |
+| Clipboard consent and copy classification     | Native clipboard service               |
+| Live reply phase and wire shape               | `@offgrid/sync` chat-stream contract   |
+| Busy-state visuals                            | Shared design-system loader primitive  |
+| User Eject All lifecycle                      | Mobile user-model-ejection coordinator |
+| Shared-file backlog and active receive window | `@offgrid/sync` `SharedFileDelivery`   |
+| Concurrent knowledge-document offers          | `@offgrid/sync` transfer reservations  |
+| Per-destination outbound transfer order        | `@offgrid/sync` `FileTransferManager`  |
+
+### Typed transfer queue end state
+
+- One logical outbound queue lives in `@offgrid/sync` and is partitioned by destination.
+- Every queued job has one stable activity ID and one category derived from the canonical transfer
+  classifier. Models, shared files, screenshots, downloads, generated media, attachments, direct
+  files, and knowledge documents use the same job contract.
+- A job may provide a feature-owned preparation callback, such as publishing a shared-file control.
+  The shared queue invokes it only when that job reaches the front. Feature services do not schedule
+  transport work themselves.
+- `FileTransferManager` moves only the active job. It emits queue and transfer state through one
+  progress contract.
+- Completed history persists state transitions from that contract. Activity and Files are read-only
+  projections; they never schedule or own transfer state.
+- Feature-level queues, concurrency gates, and duplicate outgoing-history writers are removed.
+- Per-record reconciliation and single-flight deduplication remain separate state-machine concerns;
+  they cannot decide transfer order.
+
+## Sequential work plan
+
+### Phase 0 - Freeze and record the baseline
+
+- [x] Identify the five release repositories.
+- [x] Record the current release branch heads.
+- [x] Confirm that top-level `sync` and `website` are outside this release.
+- [x] Make every release worktree clean, including the final Mobile Pro submodule pointer.
+- [ ] Record the exact full-suite baseline after the filesystem test boundary is repaired.
+
+Baseline heads at plan creation:
+
+| Repository    | Branch                  | Head           |
+| ------------- | ----------------------- | -------------- |
+| `desktop`     | `release/sync-feedback` | `79bb06ffd833` |
+| `desktop/pro` | `release/sync-feedback` | `bfca9bdf07d7` |
+| `mobile`      | `release/sync-feedback` | `10e357f82849` |
+| `mobile/pro`  | `release/sync-feedback` | `5a4769caa8d5` |
+| `shared`      | `release/sync-feedback` | `966dd99ce0bd` |
+
+### Phase 1 - Close the Mobile filesystem crash class
+
+Decision: Option A. Production must not call `RNFS.stat`.
+
+- [x] Remove executable production `RNFS.stat` calls.
+- [ ] Confirm all file readers use the one filesystem adapter.
+- [x] Add one faithful native-filesystem fake under the test harness.
+- [ ] Make tests declare a directory tree once and derive parent listings from it.
+- [ ] Replace test-local RNFS fakes with the shared boundary fake.
+- [ ] Add an architecture rule that rejects future production `RNFS.stat` calls.
+- [ ] Align `llama.rn` and the CocoaPods graph on version 0.13.
+- [ ] Run Mobile lint and TypeScript.
+- [ ] Run the complete Mobile test suite.
+- [ ] Run the iOS simulator build.
+- [ ] Verify startup model scan and debug-log flush on a physical iPhone.
+- [ ] Verify the same filesystem journeys on a physical Android device.
+
+Exit condition: zero executable production `RNFS.stat` calls, all Mobile suites pass, native builds
+pass, and both physical-device journeys pass.
+
+### Phase 2 - Make mesh sharing policy one contract
+
+- [x] Define one canonical send and receive mode for each workspace category.
+- [x] Make Chats, Projects, and Model settings send without optional controls.
+- [x] Make Generated media and Message attachments send without optional controls.
+- [x] Make Chats, Projects, Model settings, Generated media, and Message attachments required mesh data.
+- [x] Generate configurable UI rows and admission decisions from the same catalog.
+- [x] Remove the five required mesh categories from Receiving settings on Mobile and Desktop.
+- [x] Migrate the old receive master to optional data and discard stored refusals for required data.
+- [x] Merge Mobile automatic file rules into Sending and remove the Ambient sharing section.
+- [x] Remove the Ambient sharing heading from Desktop and keep one Sending surface.
+- [x] Store repeated Sending and Receiving copy in the shared package.
+- [x] Use one Mobile drop-down component for Sending destinations and Receiving sources.
+- [x] Use drop-down scope selection for both Desktop Sending and Receiving.
+- [x] Move detailed Mobile Sending and Receiving rules into bottom sheets.
+- [x] Use one reusable policy matrix for Off/Ask/Auto and Refuse/Accept decisions.
+- [x] Verify the final settings hierarchy and controls on Mobile and Desktop.
+- [x] Default Downloads to all eight supported automatic-sharing file types from one shared policy.
+- [x] Save Desktop file-type edits once on Done so rapid choices cannot overwrite each other.
+- [x] Persist one opt-in watermark per Desktop folder and baseline existing configured folders on upgrade.
+- [x] Keep folder arrival time separate from file modification time so copied downloads remain new.
+- [x] Coalesce Desktop sync invalidations at the main-process boundary during transfer bursts.
+- [x] Keep the durable shared-file backlog only on the sender.
+- [x] Publish shared-file controls only when the bounded delivery window admits the file.
+- [x] Prevent State Sync anti-entropy from announcing queued controls outside that window.
+- [x] Use the same active-control rule for normal delivery and repair on Desktop and Mobile.
+- [ ] Remove receiver-side file controls with no local or staged bytes before startup replay.
+- [x] Clear stale nonterminal receive offers from the connected iPhone and Android device.
+- [x] Join identical concurrent knowledge-document offers behind one receiver-side writer.
+- [x] Accept reconnect offers for an existing matching knowledge document without sending its bytes again.
+- [x] Make Project and Knowledge document transfer independent of legacy optional-sharing preferences.
+- [x] Enforce one active outbound transfer per destination in the shared transfer manager.
+- [x] Route models, direct files, knowledge documents, generated media, attachments, screenshots, and downloads through that manager queue.
+- [x] Remove the Desktop host queue, Mobile knowledge-document queue, shared-file concurrency gate, and repair scheduler.
+- [x] Publish shared-file controls only when their typed transfer job reaches the front of the manager queue.
+- [x] Stop exporting queue primitives to Desktop and Mobile hosts.
+- [ ] Verify that enabling Screenshots and Downloads sends only files created after enablement.
+- [ ] Verify all eight Download types can be selected on Desktop and Mobile.
+- [ ] Move Copied text into the Automatic sharing matrix on Mobile and Desktop.
+- [ ] Verify always-sync behavior for generated media and message attachments across devices.
+
+Exit condition: required mesh data has no switch and always moves; every remaining switch controls
+one optional content type; both hosts use only Sending and Receiving language.
+
+Focused evidence, 2026-08-13:
+
+- Shared ambient-directory build and all 31 source-contract tests pass, including the existing-grant
+  watermark migration.
+- Desktop ambient-folder and coalesced-invalidation suites pass: 22 tests.
+- Desktop main-process TypeScript passes.
+- The accidental local outgoing backlog was backed up, then cleared without changing pairings,
+  local files, completed history, or incoming transfers. The deliberate logo-PDF test remains queued.
+- The shared 20-file backlog test passes: submitting the backlog publishes no controls. The first
+  control publishes only when the manager activates the first typed transfer job.
+- Desktop shared-file and State Bridge suites pass: 87 tests. Desktop node TypeScript passes.
+- Mobile shared-file unit tests, explicit-share tests, and the real ambient-share integration journey
+  pass: 20 tests. The ambient journey proves that a staged control is absent before approval and is
+  published when its transfer becomes active.
+- The connected iPhone backup is retained at
+  `/tmp/offgrid-ios-asyncstorage-backup-20260813.kNt0wF`. Cleanup removed 2,066 nonterminal receive
+  rows and 2,062 matching shared-file ops. It preserved 100 completed-history rows. A read-back from
+  the phone confirms zero nonterminal receive rows.
+- The connected Android backup is retained at
+  `/tmp/offgrid-android-RKStorage-backup-20260813.sqlite`. Cleanup removed 1,136 nonterminal receive
+  rows and 1,135 matching shared-file ops. It preserved 103 other history rows. A read-back from the
+  phone confirms zero nonterminal receive rows and a valid SQLite integrity check.
+- A full mesh can offer one replicated knowledge document from two peers at the same time. Shared
+  Sync now gives matching bytes one staging-path owner and makes later offers wait for that result.
+  Shared typecheck, build, and 12 focused contract tests pass. Desktop node TypeScript and 47
+  knowledge-document tests pass. The Mobile knowledge-document integration and refusal suites pass:
+  5 tests. Mobile TypeScript and the updated Receiving policy tests pass.
+- Reconnect backfill now compares an existing knowledge document at the receiver and resumes at the
+  end when size and checksum match. The Mobile integration test proves the repeated offer performs
+  zero source reads and does not re-index the document. Project transfer progress also keeps its
+  hidden category before, during, and after live progress, including legacy rows without a stored
+  category. Shared focused tests pass: 12. Desktop
+  knowledge-document tests pass: 48. Mobile knowledge-document tests pass: 5.
+- A later Android restart proved that the first cleanup removed symptoms only: 955 remote controls
+  rebuilt 107 new 0% receiver rows before the app was stopped. The shared op-log now owns a
+  provenance-aware cleanup rule. Mobile and Desktop provide only the IDs whose bytes exist locally
+  or are fully staged. Local sender records remain. Shared typecheck and all 470 Sync tests pass,
+  including remote-history cleanup before replay. Desktop typecheck and 63 focused sync tests pass.
+  Real restart verification is pending.
+- The second device cleanup is backed up at
+  `/tmp/offgrid-mobile-cleanup-3ll5bs/android-RKStorage.before-cleanup.sqlite` and
+  `/tmp/offgrid-ios-cleanup-8dFR2k-before-cleanup`. Android removed 955 remote shared-file ops and
+  107 ghost receiver rows. iOS Debug removed four ghost receiver rows, including the dead
+  `log_list.json` row. Completed history, staged bytes, and sender-owned rows remain.
+- Physical Android restart verification: Sync Activity reopened with 78 rows instead of rebuilding
+  the previous 1,033-row ghost backlog. The one-minute no-growth observation is still pending, then
+  the same restart check moves to iOS.
+- Project and Knowledge document state was already marked required, but Mobile still consulted an
+  old raw `projects` preference before sending document bytes. That duplicate gate is removed from
+  both hosts. Mobile now normalizes every required category from the shared send-mode contract. The
+  focused Desktop knowledge-document suite passes: 23 tests, plus one real SQLite integration test.
+  The focused Mobile integration journey passes and includes a stored legacy `projects: false`
+  preference.
+- Android then proved that one Mac could still offer several files at the same time. Feature-local
+  queues did not cover every transfer path. `FileTransferManager` now owns one serial outbound queue
+  per destination for every model, shared file, attachment, and knowledge-document sender. The full
+  transfer-manager contract passes: 11 tests, including serial order, active cancellation, and
+  cancellation before a queued item is offered. The shared package no longer exports its queue
+  primitive to hosts. Shared typecheck and all 472 Sync tests pass. Desktop typecheck and 129 focused
+  transfer-owner tests pass. Mobile TypeScript, 29 receive-policy tests, 8 Activity tests, and the
+  real knowledge-document integration journey pass. Physical four-host verification is pending.
+- Physical explicit-file verification used a 163,626,750-byte DMG from macOS. Windows and Android
+  each received one active delivery in their own destination lane. iOS correctly refused Files, but
+  its Activity row stayed at Receiving 0% after macOS received the refusal. The shared transfer
+  manager now emits the same terminal failed state on the receiver for policy, peer-limit, and
+  missing-sink refusals. The real encrypted manager suite passes 12 tests, including this policy
+  refusal journey.
+- Direct inspection of the iPhone store found two IDs for each refused DMG. The durable control row
+  used the sender ID, while the transfer manager used the receiver ID. Incoming and outgoing rows
+  now derive the same destination-scoped ID in `@offgrid/sync`; host code supplies only the local
+  receiver ID and peer display facts. The shared build and 37 focused transfer and receive-policy
+  tests pass, including a real history projection that settles one queued row into one Failed row.
+  Mobile TypeScript and its knowledge-document integration pass. Desktop TypeScript and 86 focused
+  shared-file and knowledge-document tests pass. Commits `a93008a`, `72061eea`, `979cc32c`, and
+  `0fad9d1` are pushed. The Windows Shared bundle and all changed Desktop Pro files match the Mac by
+  MD5. Physical restart verification is pending.
+- macOS now keeps the Share file action pending while it copies the selected file into owned
+  storage, blocks duplicate clicks, and opens Activity after queue admission. The focused rendered
+  control test passes. Physical macOS verification is pending.
+- Generated media and message attachments now read one `hidden` visibility rule from the shared
+  sharing catalog. Durable rows, live progress, Desktop delivery rows, and file notifications all
+  use that rule. Desktop startup backfill also stops when an attachment's stable `syncId` already
+  exists, so it cannot change a completed delivery from `sent` back to `granted`. Shared Sync builds,
+  49 focused shared tests pass, 65 Desktop shared-file tests pass, and Desktop node TypeScript passes.
+  Commits `5007235` and `ef82adc` are pushed. The five delivery rows reopened by the old build were
+  restored to `sent` after a database backup and integrity check. The Windows Shared bundle and
+  Desktop Pro service match the Mac by MD5. Physical restart verification is pending.
+- The first iOS restart exposed one remaining restored-row path: nonterminal history was projected
+  as live progress with the correct hidden `kind`, but Activity ignored that field and guessed from
+  `image/png`. The shared projector now uses the transfer's canonical kind before MIME fallback.
+  The exact no-separate-durable-row regression is covered for generated media and message
+  attachments. Shared Sync builds and 51 focused tests pass. Commit `31983fa` is pushed. Physical
+  iOS verification is pending.
+
+### Phase 3 - Make transfer history authoritative
+
+- [x] Preserve transfer `kind` during all live and in-memory history updates.
+- [x] Keep hidden project transfers hidden when live progress exists.
+- [ ] Persist `kind` in Desktop SQLite.
+- [ ] Derive Retry, Cancel, and Dismiss from executable service commands.
+- [ ] Make restored Mobile Cancel update durable history without a live manager.
+- [x] Render Mobile Notifications, Activity, and Files with one virtualized list adapter.
+- [ ] Use the shared List mode as the initial and reset view on Mobile and Desktop.
+- [ ] Remove Retry when its source is not durably available.
+- [x] Persist every state transition without writing durable history on each byte update.
+- [ ] Define one stable order for memory, adapters, SQLite, retention, and restart.
+- [ ] Verify manual tests 9.3, 9.4, 9.6, and 9.7 through real stores and restarts.
+
+Exit condition: history, live progress, available actions, and restart projection agree.
+
+Current gate, 2026-08-13:
+
+- Code and wiring are present for durable Mobile Cancel. A live transfer still cancels through the
+  manager; a restored row falls back to `CompletedTransferHistory.cancel`. Physical iOS and Android
+  verification is pending.
+- Mobile Notifications, Activity, and Files use one `FlatList` adapter with bounded initial render,
+  batch size, and window size. Notifications no longer mounts every card in a `ScrollView`.
+  Activity and Files now index completed deliveries once instead of scanning the complete delivery
+  set for every file. Live device review reports that all three screens open much faster.
+- Mobile Activity uses the existing small-button action row with the shared 8-point gap token, so
+  adjacent Open, Retry, Cancel, and Dismiss actions do not touch. Physical iOS and Android review is
+  pending.
+- `DEFAULT_SYNC_FILE_VIEW_MODE` in `@offgrid/sync` is `list`. Shared projections, Mobile Activity,
+  Mobile Files, Desktop Activity, Desktop Files, and Desktop file notifications use it. Desktop
+  typecheck passes. Physical UI verification is pending.
+
+### Phase 4 - Fix the remaining Shared contracts
+
+- [ ] Validate model-origin `repoId`, `revision`, and `path` at the manifest boundary.
+- [ ] Keep compatibility with senders that omit origin.
+- [ ] Reject malformed origin values before persistence.
+- [ ] Base Reconnect and Rename on a real pairing credential.
+- [ ] Keep Evict available for license-only rows.
+
+Exit condition: every displayed action is executable and every stored model origin is valid.
+
+### Phase 5 - Fix Desktop discovery
+
+- [ ] Make the discovery service own one current endpoint object.
+- [ ] Update it when the network interface changes.
+- [ ] Build both the listening socket and Bonjour TXT record from it.
+- [ ] Test the re-advertised TXT address, not only the watcher callback.
+- [ ] Verify Wi-Fi to Ethernet and Ethernet to Wi-Fi without app restart.
+
+Exit condition: peers always dial the current Desktop address.
+
+### Phase 6 - Fix Desktop pending attachments and chat edits
+
+- [ ] Make the shared-file service own a replayable pending-file snapshot.
+- [ ] Deliver the current snapshot to every new subscriber before later updates.
+- [ ] Preserve attachment identity and metadata during edit.
+- [ ] Put edit, persistence, history construction, and regeneration behind one conversation command.
+- [ ] Remove model-history construction from stale React state.
+- [ ] Verify late Chat mount, edit plus attachment sync, reopen, and regeneration.
+
+Exit condition: loaders survive late mount, edited attachments sync, and the model receives only the
+edited prompt.
+
+### Phase 7 - Fix Desktop thinking capability
+
+- [ ] Reset model capability state on every reload.
+- [ ] Make the active model session own its thinking dialect.
+- [ ] Bound `/props` with a timeout and explicit failure state.
+- [ ] Never reuse a previous model's dialect after probe failure.
+- [ ] Verify Muse to Qwen and Qwen to Muse for success, failure, and timeout.
+
+Exit condition: the Thinking control always sends the active model's supported option.
+
+### Phase 8 - Fix Android clipboard consent and classification
+
+- [ ] Put Clipboard Sync enabled state in the native clipboard service.
+- [ ] Check consent before the accessibility service reads selected text.
+- [ ] Clear selection memory when sync is disabled.
+- [ ] Require verified text metadata before selection fallback.
+- [ ] Ignore image, file, and unknown clipboard events.
+- [ ] Add native tests for Off, non-text, stale selection, and valid text fallback.
+- [ ] Verify manual test 3.6 on a physical Android device.
+
+Exit condition: non-text copies stay quiet and selected text is not read or sent while Off.
+
+### Phase 9 - Fix vision-repair provenance
+
+- [ ] Pass repository, revision, and path through the provider contract.
+- [ ] Use the recorded revision for tree listing and download URLs.
+- [ ] Do not default a pinned transferred model to `main`.
+- [ ] Capture one real Hugging Face boundary response and replay it offline.
+- [ ] Verify a tag or commit receives its matching projector.
+
+Exit condition: repair preserves the transferred model's exact provenance.
+
+### Phase 10 - Unify loading states
+
+- [x] Define one ephemeral live-turn contract: Waiting, Thinking, Answering, and Generating image.
+- [x] Make Desktop text, reasoning, direct image, and tool-deferred image paths publish that contract.
+- [x] Make Mobile text, reasoning, and image-generation services publish that contract.
+- [x] Render the same remote phases on Desktop and Mobile without device-attribution banners.
+- [x] Use one Desktop Thinking block for local, saved, and remote reasoning.
+- [ ] Verify Desktop-to-Desktop, Desktop-to-Mobile, Mobile-to-Desktop, and Mobile-to-Mobile.
+- [x] Keep one Desktop remote-reply placeholder alive from tool streaming through deferred image
+      generation, and replace it only when the durable image message arrives.
+- [x] Remove the separate `Off Grid AI - answering on <device>` label from Desktop remote replies.
+- [ ] Keep Mobile `LoadingDots` as the one Mobile implementation.
+- [ ] Add a production-ready web `LoadingDots` primitive to the component library.
+- [ ] Include tokens, ARIA, and reduced-motion behavior.
+- [ ] Consume it through one thin Desktop adapter.
+- [ ] Replace rotating rings and local dot implementations in the manual-test scope.
+- [ ] Add a real pending state to Share and disable duplicate intent while pending.
+- [ ] Verify all manual-test C states by screenshot and interaction.
+
+Exit condition: every target surface uses the same three-dot behavior and no pending action can be
+submitted twice.
+
+### Phase 11 - Full verification
+
+- [ ] Build and test `shared`.
+- [ ] Build and test `desktop/pro`.
+- [ ] Build, test, and package `desktop`.
+- [ ] Build and test `mobile/pro`.
+- [ ] Lint, typecheck, test, and build Android and iOS in `mobile`.
+- [ ] Run physical iOS and Android journeys.
+- [ ] Run the complete manual test document from a clean install.
+- [ ] Run the restart, reconnect, and network-change cases again.
+- [ ] Inspect every required screenshot and interaction recording.
+
+### Phase 12 - PR and review train
+
+- [ ] Push `shared` and finish its review loop.
+- [ ] Push `desktop/pro` and finish its review loop.
+- [ ] Push `mobile/pro` and finish its review loop.
+- [ ] Push `desktop` and finish its review loop.
+- [ ] Update the Mobile Pro pointer, push `mobile`, and finish its review loop.
+- [ ] Merge in dependency order with merge commits.
+
+## Progress log
+
+### 2026-08-13 - Mobile Sync list performance
+
+- Code: the Notifications feed now projects one typed heterogeneous row list and renders it through
+  the same `SyncVirtualizedList` adapter used by Activity and Files.
+- Code: the Mobile file projection indexes completed deliveries by `syncId` in one pass. Activity
+  and Files no longer do file-count times delivery-count work before the list appears.
+- Wired: Notifications uses one All, Approvals, File transfers, or Recent drop-down. Clear recent is
+  one accessible icon on its right. The shared drop-down renders its options as an overlay, so it
+  does not move the list below it. Live transfer progress remains in Activity only.
+- Gate: Mobile TypeScript and focused Pro lint pass. The standalone Pro TypeScript command remains
+  blocked by three pre-existing `audio/services/ttsService.ts` errors against the installed
+  `llama.rn` types.
+- Verified: live device review confirms that Notifications, Activity, and Files are much faster.
+  Commits `48d6ca64`, `e84e6f72`, and `ac934761` record the projection, list, and overlay changes.
+
+### 2026-08-13 - Plan created
+
+- Created this progress source of truth.
+- Confirmed the five release repository heads shown above.
+- Confirmed that Mobile has no executable production `RNFS.stat` call. One explanatory comment still
+  names the old call.
+- Current Mobile worktree change is the `pro` submodule pointer.
+- Phase 1 remains in progress because the full test boundary migration and gates are not yet green.
+
+### 2026-08-13 - Download file-type policy
+
+- Code: `@offgrid/sync` now owns the eight-type default for Desktop and Mobile.
+- Code: the previous six-type default resolves to the new eight-type default without changing a
+  user's custom subset.
+- Code: Desktop file-type choices now use a local draft and one save on Done. This removes the
+  concurrent last-write-wins failure seen with Presentations, Audio, and Video.
+- Wired: Desktop and Mobile read the same shared default. Their reset actions now mean all supported
+  types.
+- Gate: Shared build, Shared TypeScript, focused Shared policy tests, Desktop renderer TypeScript,
+  and focused Mobile/desktop lint passed with no errors.
+- Gate: Mobile full TypeScript remains blocked only by the previously recorded stale Receiving test
+  contracts. This change added no Mobile source error.
+- Verified: physical UI verification is pending. The new Desktop dialog is identifiable by the
+  `Select all` action; the old build says `Documents and images`.
+
+### 2026-08-13 - Draft PRs published
+
+- Published the exact local release branch heads as draft PRs so the complete deltas can be reviewed.
+- Skipped the pre-push hooks for this publication at the owner's explicit direction. The skipped or
+  failed gates remain open work. No PR is merge-ready.
+- Uploaded the Desktop branch's 88 referenced Git LFS objects before GitHub accepted the branch.

+
+### 2026-08-13 - Mobile filesystem boundary, incremental verification
+
+- Added one stateful, directory-based native filesystem boundary in
+  `__tests__/harness/nativeFileSystem.ts`.
+- Updated file-sharing validation and the Oute/Qwen audio asset suites to use that boundary.
+- Pushed commits `f093c65f`, `3379b68b`, and `783dc27f` to Mobile draft PR #628.
+- Switched to one defect, one focused gate, one commit, and one push so each change can be verified
+  manually before the next defect starts.
+- Repaired the debug-log rotation suite. It now uses real stored bytes and parent directory entries;
+  all 12 tests pass, including rotation after the 5 MB limit.
+
+### 2026-08-13 - One Receiving switch per content type
+
+- Removed the second Generated media and Message attachments definitions from the shared receive
+  policy. The ambient source catalog is now their only owner.
+- Proved the original failure before the fix: the policy projected two Generated media rows.
+- Proved the complete policy path after the fix: one row, one category ID, Off in the projection, and
+  refused incoming bytes.
+- Proved that stored `generated_media` and `message_attachment` refusals remain effective after an
+  upgrade.
+- The full `@offgrid/sync` suite passes: 468 tests. Its build and TypeScript gate pass.
+- The rendered Mobile Receiving section passes 11 tests and shows one switch for each category.
+- Manual iPhone verification confirms that the Receiving section shows exactly one Generated media
+  switch and one Message attachments switch.
+- Manual Desktop-to-iPhone verification confirms the default Generated media path end to end: the
+  Desktop loading state appeared, generation completed, sync transferred the image, and Mobile
+  rendered the image in the correct chat.
+- Manual Desktop-to-iPhone verification also confirms policy independence: with Files Off and
+  Generated media On on iOS, the generated image still transferred and rendered in the correct
+  chat.
+- Windows showed the image loading component and then replaced it with the generated image. Treat
+  this as supporting UI evidence only because the installed Windows build version was not confirmed.
+- Product decision changed after that verification: Chats, Projects, Model settings, Generated media,
+  and Message attachments are required mesh data. Shared now gives every category one `always` or
+  `configurable` receive mode. The same field drives admission, normalization, and both host
+  projections.
+- Shared builds with the new contract. A direct production-contract probe shows that the four
+  required categories still arrive with optional receiving Off, while direct Files are refused.
+- An iPhone screenshot confirms that Chats, Projects, Generated media, and Message attachments are
+  absent from Receiving. Model settings was removed after the next review. The remaining rows come
+  from the shared configurable projection.
+- Shortened the Receiving hint to one sentence and added token-based spacing above the scope
+  description after device review.
+- Product decision also changed Sending: Chats, Projects, and Model settings now send as required
+  mesh state. Shared send modes enforce this even if an older stored preference disabled a row.
+- Generated media and Message attachments are also required send data. They are absent from the
+  Automatic sharing matrix, ignore old stored Off/Ask rules, and queue while a peer is offline.
+- A direct shared-package probe confirms that the configurable projection now contains only
+  Screenshots and Downloads, while Generated media queues even with optional sending and offline
+  queueing turned off.
+- Mobile now has only Sending and Receiving accordions. Automatic file rules and direct file sharing
+  are inside Sending. Desktop uses the same model and no longer shows an Ambient sharing heading.
+- Sending and Receiving explanations now come from one shared copy object used by both hosts.
+- Replaced the device chip rows with one selected-device drop-down. Mobile Sending and Receiving use
+  the same reusable control. Desktop Receiving now matches its existing Sending destination select
+  and supports per-device category rules through the shared policy.
+- Replaced the long Mobile rule lists with progressive disclosure. The main screen now shows compact
+  Automatic sharing and Receiving rules summaries. Each Configure action opens a bottom sheet using
+  the same policy-matrix primitive, with Off/Ask/Auto for sending and Refuse/Accept for receiving.
+- Added token-based space below the Automatic sharing sheet header after physical iPhone review.
+- Corrected the Desktop hierarchy after screenshot review: Sending and Receiving are now separate,
+  equal top-level panels. Receiving is no longer nested inside the Sending surface.
+- Fixed the receive-master migration precedence. A stored legacy `enabled: false` value can no longer
+  override a new `optionalEnabled: true` selection. The same normalization rule handles global and
+  per-device receive masters.
+- Removed Model settings from Receiving. Its shared catalog entry is now required in both directions,
+  so admission and both settings surfaces use the same rule.
+- The shared build passes. A direct production-package probe confirms that legacy global and
+  per-device receive masters can be enabled and that the configurable receive catalog contains only
+  Copied text, Screenshots, Downloads, Files, and Models.
+- Manual review confirms that the final Mobile and Desktop settings hierarchy and controls are
+  correct. Policy behavior remains a separate device gate.
+- Repaired the Windows development mirror address from `192.168.1.28` to `192.168.1.97` and restarted
+  its LaunchAgent. A download-based full comparison found zero differences across 1,202 mirrored
+  Desktop files and 467 mirrored Shared files. The Shared Sync production bundle also matches by MD5.
+- Manual Mac image generation produced a complete image, and Windows received the final image. The
+  Windows pending-image loader did not appear. This is now the next UI defect after runtime-message
+  filtering.
+- A synced Mobile runtime notice was rewritten without its `notice` context and rendered on the Mac
+  as a normal assistant reply with Speak, Copy, and Regenerate actions. Shared now owns one
+  `isRuntimeOnlyMessage` rule for current marked notices and legacy `Model loaded` or `Model unloaded`
+  rows. The shared receive projection and both host outbound adapters use that rule, so runtime state
+  neither enters the mesh nor renders from old received rows.
+- The shared build passes. A direct production-package check drops both current and legacy runtime
+  notices while preserving an ordinary assistant sentence that contains the words `model loaded`.
+- Shared builds with the final send and receive contract. Focused lint and diff checks pass. Host
+  screenshots and final physical-device behavior remain to be verified.
+- Physical-device verification of the final copy, spacing, and stored-policy migration is still
+  required.
+- The separate Desktop chat defect remains open: with Tools or Connectors enabled, an explicit
+  `draw` request can return false success text without calling the image-generation tool.
+- Fixed the Windows remote-image loading gap. Desktop now treats text-tool execution and deferred
+  image generation as two phases of one live turn, under one message ID. Native image progress keeps
+  the same preview alive; success, failure, or cancellation closes it through the image-job owner.
+- Removed the Desktop-only `Off Grid AI - answering on <device>` banner. Normal replies now stream as
+  the standard assistant bubble, and the image phase uses the shared Desktop three-dot chat loader.
+- Added a replayable live-stream snapshot for a Chat view that mounts after generation starts.
+- Shared live-stream integration tests pass (24 tests), Desktop lifecycle tests pass (11 tests),
+  Desktop node and web TypeScript checks pass, and the production build passes. The Windows mirror
+  matches the Mac by MD5 for the Shared bundle and all changed loader-path files. Physical Windows
+  replacement behavior is ready for manual verification.
+- Replaced the image-only live activity flag with one shared four-phase live-turn contract. The
+  transfer queue remains the durable file-transfer owner and does not carry ephemeral chat state.
+- Desktop direct image mode now starts a live turn even when no text stream came first. Desktop
+  reasoning uses one collapsible Thinking component for local and received replies.
+- Mobile Sync now observes the image-generation service as well as the chat store. It sends the same
+  stable message ID in the live preview and the durable image message, and it closes the preview
+  before the durable mutation leaves the phone.
+- Mobile received previews now use the normal chat renderer for Waiting, Thinking, Answering, and
+  Generating image. Remote rows are marked as streaming, so actions stay hidden until the durable
+  message arrives.
+- Current gate: Shared Sync build and 24 live-stream tests pass. Desktop lifecycle tests, node and web
+  type checks, and production build pass. Mobile lint has zero errors in the changed source. Mobile
+  TypeScript is blocked only by stale Receiving-policy tests from Phase 2; per the Mobile rule, those
+  tests wait until physical verification is complete and the owner asks for test work.
+- Windows `.97` matches the Mac by MD5 for the rebuilt Shared Sync bundle, Desktop live-stream owner,
+  and Desktop remote-preview renderer. The mirror error log still contains old `.28` failures, but
+  direct `.97` hashes prove the files used for this test are current.
+- Physical iPhone vision verification passes. A phone image request reached the model and rendered
+  the complete result correctly in Chat.
+- Found two remaining Mobile-to-Desktop image defects during that run. Desktop rendered a received
+  image attachment as a file chip, and Mobile prompt enhancement included a local model-load notice
+  in model context. Desktop now routes received image attachments through its existing image preview
+  and lightbox. Mobile now filters enhancement context and final output through the shared
+  `isRuntimeOnlyMessage` contract.
+- Focused evidence is green: the Shared Sync build and runtime-notice contract pass; the rendered
+  Desktop image journey passes 14 tests; Desktop web TypeScript passes; changed Mobile source lint
+  passes. Full Mobile TypeScript remains blocked by the already-recorded stale Phase 2 policy tests.
+- Windows `.97` now matches the Mac by MD5 for both the rebuilt Shared Sync bundle and the changed
+  Desktop Chat renderer. The mirror daemon is running; its last error lines are old `.28` records.
+- Published Shared `ea2d8e8`, Desktop `8e05797`, and Mobile `7e012023` to the existing draft PR
+  branches. Publication used `--no-verify` under the owner's standing instruction; focused gates are
+  recorded above and the full Mobile gate remains open.
+- Android device logs confirmed that Eject All unloaded three resident models and released about
+  2.1 GB. The missing answer was a separate context-budget defect: an 8K-context llama model received
+  `n_predict: 8192`, which left no prompt space and caused native `Not enough context space` before
+  inference. Mobile now derives the effective output cap from the loaded context through one shared
+  budget policy. Conversation compaction reads the same prompt-budget constant. Changed source lint
+  passes. Physical Android verification is pending.
+- User Eject All now has one coordinator for Home and Chat. It cancels text generation, image
+  generation, and an in-progress compaction retry before it releases model memory. Stop now marks a
+  turn cancelled even between native attempts, and the compaction owner checks that state before it
+  retries. The text-residency check also uses the active engine contract, so LiteRT is no longer
+  omitted. Changed source lint has zero errors, and TypeScript has no new errors beyond the recorded
+  stale Phase 2 Receiving-policy tests. Physical Android verification is pending.

+# Android to mesh image test
+
+This physical test starts image generation on Android. It then checks the same journey on Android,
+iOS, macOS, and Windows.
+
+It verifies:
+
+- the synced chat opens without an app restart;
+- a live Enhancing, Loading image model, or Generating image state appears;
+- the live state ends when the saved result arrives;
+- the prompt and one decoded image are in one message bubble;
+- `Image arriving` does not remain;
+- the new decoded image appears in Gallery;
+- screenshots and a JSON result are saved for every device.
+
+## Preconditions
+
+- All devices are already paired and connected on the mesh.
+- Android is visible to `adb`.
+- WebDriverAgent is available at `WDA_URL` for the iPhone.
+- Off Grid Desktop runs with CDP on local port 9222 for macOS.
+- The Windows CDP tunnel uses local port 9224.
+- Android has an image model downloaded. The test selects it through forced image mode.
+
+Run this command on the Mac that owns the device-control channels:
+
+```sh
+npm run e2e:image-sync
+```
+
+The default mesh is `ios,macos,windows`. Use a smaller observer set only for diagnosis:
+
+```sh
+npm run e2e:image-sync -- --mesh ios,macos --timeout-minutes 30
+```
+
+The run does not pair, forget, disconnect, restart, or change mesh membership. Evidence is written to
+`.artifacts/e2e-flows/generated-image-sync/`.
+
+## Reliable physical-device setup
+
+Use this setup before the first app action. Do not let the journey runner discover devices by trial
+and error.
+
+### 1. Confirm the four apps
+
+- Keep Android, iOS, macOS Desktop, and Windows Desktop open.
+- Keep the iPhone unlocked. Accept the iOS trust prompt and enter the trust code when iOS asks.
+- Confirm Android is visible before opening or creating a chat:
+
+```sh
+adb devices -l
+adb -s 505b53a0 shell pidof ai.offgridmobile.dev
+```
+
+### 2. Start WebDriverAgent on the correct iPhone
+
+Do not run the launcher without `WDA_UDID` when `xctrace` lists this Mac as a device. The automatic
+selection can choose the Mac instead of the iPhone.
+
+Find the available paired iPhone:
+
+```sh
+xcrun devicectl list devices
+xcrun xctrace list devices
+```
+
+Start WDA with the physical iPhone UDID printed by `xctrace`:
+
+```sh
+cd mobile
+WDA_UDID=<physical-iphone-udid> node scripts/ios/launch-wda.mjs
+```
+
+Leave that process running. It prints the device URL, for example:
+
+```text
+WDA_URL=http://192.168.1.14:8100
+```
+
+Verify the URL before the journey:
+
+```sh
+curl -fsS "$WDA_URL/status"
+```
+
+The result must say `ready: true`. If `xcodebuild` exits before WDA serves, keep the phone unlocked,
+accept its trust prompt, and run the explicit `xcodebuild test-without-building` command once to see
+the device error. Do not navigate in Off Grid while repairing WDA.
+
+### 3. Start both Desktop apps with CDP
+
+Run macOS Desktop on the Mac that owns the device controls:
+
+```sh
+cd desktop
+npm run dev -- --remoteDebuggingPort 9222
+curl -fsS http://127.0.0.1:9222/json/list
+```
+
+Run one Windows Desktop dev process in the Windows VM:
+
+```powershell
+cd C:\Users\oga\ogad-git
+npm run dev -- --remoteDebuggingPort 9224
+```
+
+Do not start a second dev process. Stop old `node`, `electron`, or `llama-server` processes first if
+Windows reports `EADDRINUSE`.
+
+Before starting Windows, follow `REMOTE_WINDOWS_DEV_MIRROR.md`. Hash at least the Shared `models`
+and `sync` package entry files on both machines. A missing `@offgrid/models/dist/index.js` means the
+Windows Shared mirror is stale; restarting the app alone cannot repair it.
+
+### 4. Check all control channels
+
+Run these checks before any chat action:
+
+```sh
+adb devices -l
+curl -fsS "$WDA_URL/status"
+curl -fsS http://127.0.0.1:9222/json/list
+curl -fsS http://127.0.0.1:9224/json/list
+```
+
+Do not send a prompt when one channel is missing. Repair the control channel first.
+
+## Safe staged journey
+
+### Source-first selectors
+
+Before automating any control, read the component source and use its owned `testID` or accessibility
+identifier. Do not infer a selector from visible copy, an icon glyph, accessibility-tree order, or a
+screen coordinate. For example, the Android chat Send icon is owned by
+`src/components/ChatInput/index.tsx` and uses `testID="send-button"`; the E2E clicks that element
+through Appium UiAutomator2.
+
+If a required control has no stable identifier, add one in the component source first. Then rebuild
+the app and use that identifier in the journey.
+
+Use the staged journey for an attended physical test. The one-shot command is for a fully proven
+setup only.
+
+- Create one uniquely named E2E chat.
+- Wait until that same chat appears once on all four devices.
+- Open it once on iOS and keep iOS on that chat.
+- Record the starting message and Gallery counts.
+- Arm all observers before Android sends.
+- Send one unique image prompt from Android exactly once.
+- Never retry the send action automatically after a timeout or navigation error.
+- Do not create a replacement chat after a failure.
+- Do not press Back on iOS while live or final chat verification is in progress.
+- Verify the live state and final decoded image in the chat first.
+- Verify Gallery later as a separate action. A Gallery navigation failure must not restart the chat
+  journey or resend the prompt.
+- Stop at the first failed visible action. Capture the current screen and report the exact platform
+  and phase before any recovery action.
+
+This staged order prevents a failed iOS Back action from creating repeated chats or repeated image
+requests.
+
+### Replay an attended Thinking checkpoint
+
+Use the staged Thinking runner after the normal Text checkpoint exists. Every command records the UI
+text and a screenshot before and after its action. It also appends an action ledger and keeps durable
+journey state in the checkpoint evidence directory.
+
+```sh
+npm run e2e:thinking-sync -- \
+  --step snapshot \
+  --run <checkpoint-marker> \
+  --ios http://<iphone-ip>:8100
+
+npm run e2e:thinking-sync -- \
+  --step open-chat \
+  --run <checkpoint-marker> \
+  --ios http://<iphone-ip>:8100
+
+npm run e2e:thinking-sync -- \
+  --step open-settings \
+  --run <checkpoint-marker> \
+  --ios http://<iphone-ip>:8100
+
+npm run e2e:thinking-sync -- \
+  --step prepare-thinking \
+  --run <checkpoint-marker> \
+  --ios http://<iphone-ip>:8100
+
+npm run e2e:thinking-sync -- \
+  --step run-thinking \
+  --run <checkpoint-marker> \
+  --ios http://<iphone-ip>:8100
+```
+
+Use `--step probe-send` before the first live run on a new Android build. It resolves
+`testID="send-button"`, records the native node attributes and screenshot, and does not click it.
+If the Text turn has no selected text model, Send intentionally opens `ModelSelectorModal` and saves
+the draft as pending. The runner selects Qwen through
+`testID="text-model-row-unsloth/Qwen3.5-0.8B-GGUF"`; `handleModelSelect` then resumes the pending turn
+once. Do not use the header's `model-selector` for this: that identifier opens Models Manager.
+
+Run one step at a time until the route is proven. The runner opens only the chat whose marker was
+passed in `--run`; it does not create a replacement chat. Add `--platform android`, `ios`, `macos`,
+or `windows` to stage one device at a time. `run-thinking` reserves its unique send in
+`thinking-state.json` before it taps Send and refuses a second send after a failure or rerun.
+If a control-channel failure misdirects the tap, run `--step recover-unsent`. Recovery succeeds only
+when the marker is absent on all four devices and Android is on the clean checkpoint chat.
+If the marker remains only as an Android composer draft, use `--step recover-draft`. It preserves the
+draft and clears the reservation only after it proves no sent message exists on any device.

+# Model residency journeys (real device)
+
+Three E2E journeys that answer what the jest suite cannot: on a real phone, **which models are
+actually in memory, what do they really cost, and what happens when the next one needs the room.**
+
+The jest suite proves the accounting with faked RAM. Only a device can say whether the numbers the
+app predicts match the memory it then uses.
+
+| Script | What it drives | Answers |
+|---|---|---|
+| `model-residency-journey.mjs` | Types "draw …" in a chat | Does an image request load the image model, and behind what? |
+| `voice-image-intent-journey.mjs` | **Speaks** "draw …" out loud | The same, with the microphone and STT included |
+| `model-eviction-journey.mjs` | Typed turn → spoken turn → image request | What co-resides, and what leaves when contention arrives |
+
+```bash
+node scripts/e2e/model-residency-journey.mjs     --ios http://192.168.1.14:8100
+node scripts/e2e/voice-image-intent-journey.mjs  --ios http://192.168.1.14:8100 --say "draw a red bicycle"
+node scripts/e2e/model-eviction-journey.mjs      --ios http://192.168.1.14:8100
+```
+
+Evidence lands in `.artifacts/e2e-flows/<journey>/<runId>/*.json` — every residency reading, with the
+RAM the app attributed to each model.
+
+## Speaking to the phone
+
+A physical phone's microphone is hardware. WDA taps and types, devicectl copies files, and neither
+can inject audio. So the Mac **says the words out loud** (`say` → `afplay`) and the phone hears them
+across the desk. That is not a simulation of the STT path — it is the STT path, microphone included.
+
+Confirmed working end to end: spoken "draw a simple green square robot" → whisper → image intent →
+prompt enhancement → a rendered picture, synced to macOS, Windows and Android.
+
+Two requirements: the phone within earshot with the volume up, and the microphone permission already
+granted — the first run after a fresh install raises a system prompt that swallows the turn.
+
+## Reading residency
+
+All four rows (`models-row-text|image|voice|speech`) **always render** — a row is the model slot, not
+the model. What marks a model as resident is its `-ram` row, which exists only once something is
+actually in memory. Reading the rows instead would report every device as fully loaded.
+
+Two device details cost real time and are worth keeping written down:
+
+- The row's composed label starts with an **icon-font glyph** (U+F185 …), not a comma. Anchoring a
+  match to `", IMAGE,"` silently never fires, and every reading comes back with no costs in it.
+- `tapWhenReady('model-selector')` does **not** open this sheet on iOS; `tapLabel` does. The failure
+  looks exactly like an empty residency rather than like a control that was never pressed.
+
+## What the first runs found
+
+On the iPhone, 16 Aug 2026:
+
+```
+in memory: image + voice + speech
+  text    Qwythos-9B-v2-GGUF                       (selected, NOT resident)
+* image   3.6 GB  SD 1.5 Palettized (Core ML)
+* voice   0.3 GB  Kokoro TTS · Warm
+* speech  0.1 GB  Base
+
+never resident at any stage: text
+```
+
+Three models co-reside and hold 4.0 GB. The **selected text model never becomes resident at any
+stage** — not for a typed turn, not for a spoken one, not for the image request — while the app still
+returns replies and pictures. The matching in-chat message is real and was captured on device:
+
+> Prompt enhancement skipped — Generating from your original prompt — Not enough free memory to load
+> this model. Close other apps or choose a smaller model.
+
+That is the memory-estimate work in `docs/GAPS_BACKLOG.md` showing up on a real device, and it is why
+these journeys report the resident set rather than only "did a picture appear".

+ * on. This reuses the guided journey's declarative list and its toggle helper with every tool asked

+Off Grid AI is building a private intelligence layer that connects people, devices, systems, data, and conversations without forcing sensitive information into the cloud. Its goal is simple: enable every person to operate with the intelligence and capabilities of the entire enterprise.
+
+The platform has three core products. Off Grid AI Mobile and Desktop run AI locally on phones and computers, allowing users to work with text, voice, images, documents, and personal context while keeping raw data on-device. Off Grid AI Console brings this intelligence into the enterprise, combining it with company systems and knowledge to create governed agents, apps, and automations.
+
+The key difference is that intelligence is captured where work actually happens, then transformed into useful signals that can be shared safely. Enterprises can apply permissions, policies, auditability, evaluations, and human approvals without sacrificing speed.
+
+Off Grid AI is open source and already has more than 180,000 downloads, thousands of GitHub stars, and meaningful early revenue. The broader vision is to give organizations the agility of a startup while retaining the security, reliability, and governance required by large enterprises.
+
+For individuals, this means AI that remembers context privately. For enterprises, it means turning distributed knowledge into repeatable execution.

+ * Physical phone -> mesh generated-image journey.
+ *
+ * Preconditions: the four apps are already paired and connected. This runner does not change mesh
+ * membership. It starts one image on the PRODUCER and observes every named peer at the same time.
+ *
+ * `--primary` names the producer, exactly as attended-thinking-sync does. It used to be hardwired
+ * to Android: the producer was `kinds[0] = 'android'` and naming android in --mesh was rejected
+ * outright, so an iPhone could only ever watch. Both phones run the same React Native tree with the
+ * same testIDs, so the journey is the same on either.
+ *
+ * Run on the Mac that owns WDA and both desktop CDP endpoints:
+ *   npm run e2e:image-sync
+ *   npm run e2e:image-sync -- --primary ios --mesh android,macos,windows
+ *   npm run e2e:image-sync -- --primary ios --enhancement off
+ *
+ * `--enhancement on|off` sets prompt enhancement on the producer before it generates - enhancement
+ * adds a whole model pass before the image, so the two settings are genuinely different journeys.
+ * Omit it to use whatever the device is already set to.

+ * This is the composer path, and it is deliberately not the project Knowledge Base path: a
+ * Knowledge Base document is attached to a PROJECT and indexed, while these ride on a single turn.
+ * The handoff doc lists "multiple attachments in one turn - pdf + text + image on a single message"
+ * as uncovered by any journey, and this is that journey.
+ *
+ * It exists because driving it by hand on 2026-08-16 found a real defect immediately: the PDF
+ * reached desktop as a chip reading "mobile.pdf text" whose preview opened empty, while Android
+ * rendered the same message correctly - two renderers each deciding what an attachment is, and
+ * drifting. A journey that sends only images would never have found it.

+ *
+ * WHY THE THREE SOURCES ARE NOT INTERCHANGEABLE, on iOS:
+ *
+ *   camera    fully addressable - `PhotoCapture` then `Use Photo` are real elements.
+ *   library   NOT addressable. The system picker exposes only PXG* layout groups and ONE
+ *             concatenated label listing every photo; there are no per-photo cells and no rects.
+ *             So the first item is taken by a geometric tap on the grid's first position. Android's
+ *             approach - XPath on content-desc="Photo taken on ..." - has no equivalent here.
+ *   document  addressable, but the picker names a file "mobile, pdf": the extension is a separate
+ *             accessibility component, so searching for "mobile.pdf" never matches.

+ *   GPU            on, because a CPU-only run is a different engine path entirely
+ *   enhancement    off or on, chosen per run - it adds a whole model pass before the image
+ *
+ * Values are TYPED into each slider's value field rather than dragged: a drag lands wherever the
+ * gesture ends, which is how a "maximum steps" run quietly becomes a 47-step one.
+ *
+ * Driven through Appium rather than `uiautomator dump`. The dump serialises the WHOLE hierarchy in
+ * one shot and is killed outright on a long transcript - the exact chat an image journey runs in -
+ * so every label lookup misses and the failure reads as "the app has no home screen". Appium's

+ * The two-device voice conversation, driven end to end.

+ * has to hear iOS finish and take its own turn. Nothing is stubbed: real microphones, real speakers,
+ * real VAD, real TTS. Every fault this evening was invisible to anything that did not go through air.
+ *
+ * Two hard lessons are baked in, because both wasted a whole run:
+ *
+ * 1. READ THE APP'S LOG FILE, not the platform log. `console.log` under Hermes goes to Metro, so
+ *    `adb logcat` returns nothing for our lines and `devicectl process monitor` returned nothing at
+ *    all. The app writes every line to Documents/offgrid-debug.log, and that file is the only source
+ *    that works on both platforms.
+ *
+ * 2. NEVER tap blind coordinates. A guessed y=2100 was the Image Gallery card, so every run opened the
+ *    gallery instead of recording. Android controls are resolved from a uiautomator dump by label, and
+ *    iOS by accessibility id.
+ *
+ * Reports the STAGE each device reached, so a failure names a subsystem rather than a symptom, and
+ * surfaces [TTS-PERF] so slowness is attributed to synthesis or to scheduling rather than guessed at.

+ * into the phone's microphone. Nothing is injected. This is the only way to exercise STT on a
+ * physical device - and it works; the sequence below is a script of a run that was confirmed by hand:
