parseThinkingContenthardcodes delimiters instead of deriving fromREASONING_DELIMITERS.The header comment states both parsers "derive the reasoning-vs-answer split from THIS set," but
parseThinkingContentuses independent hardcoded regexes (Lines 194-195, 217-218, 256-257) rather than iteratingREASONING_DELIMITERS. This is the same drift class the grammar is meant to eliminate; a delimiter added to the array won't be honored here unless the contract test catches it.

💡 Edge Case: ThinkTagParser never flushes trailing partial-opener at stream end
In the generalized ThinkTagParser, handleOutsideThink now holds back the longest suffix of the buffer that is a prefix of ANY reasoning opener (maxPartialTagSuffix over REASONING_DELIMITERS). Since there is no end-of-stream flush of the parser (the only entry point is process(), called per-delta in processDelta, and finalizeStreamingMessage consumes only the accumulated onToken output), a held-back suffix on the final chunk is silently dropped from the visible answer.
This was largely pre-existing for <think>, but the new grammar widens the withheld set: openers like <|channel|>analysis<|message|> and <|channel>thought mean a final chunk ending in <| (previously emitted, since <| is not a prefix of <think>) is now held back and lost. The risk is low (remote answers rarely end mid-token on a tag-like prefix) but real. Consider adding an explicit end()/flush() method that emits any residual buffer, and call it when the stream completes.
Flush residual buffer when the stream ends so a trailing partial-opener is not dropped.:
// Add to ThinkTagParser and call on stream completion (after the last delta):
end(onToken: (t: string) => void, onReasoning: (t: string) => void): void {
if (this.buffer.length === 0) return;
// No more data is coming: a held-back partial tag is just text/reasoning now.
if (this.inThinkBlock) onReasoning(this.buffer);
else onToken(this.buffer);
this.buffer = '';

💡 Edge Case: regenerate no longer falls back to text when image model is gone
In regenerateResponseFn the old guard if (shouldGenerateImage && deps.activeImageModel) was replaced by if (kind === 'image'), dropping the deps.activeImageModel check (src/screens/ChatScreen/useChatGenerationActions.ts:493-497). For a recorded image turn whose image model was later removed/deselected, a resend/edit now routes to handleImageGenerationFn, which alerts "No image model loaded" and returns — it no longer falls through to text generation. Note dispatchGenerationFn KEPT the && deps.activeImageModel guard (line ~424), so the two seams that were unified now diverge in this edge case. This is defensible behavior (a recorded image turn should stay an image turn), but the divergence is subtle and worth an explicit decision. For legacy turns (no recordedKind) there is no regression because shouldRouteToImageGenerationFn already returns false when activeImageModel is falsy.

💡 Quality: New engines.ts functions have no direct test; some branches uncovered
engines.ts adds several exported functions (isModelReady, activeTextCapabilities, activeLocalTextCapabilities, isLiteRTAvailable, wantsLeadingThinkToken) but there is no dedicated engines test file — they are only exercised indirectly through the hook tests. The repo standard requires 100% branch coverage on new code. Notably the llama Gemma-4 branch of wantsLeadingThinkToken (the llmService.isGemma4Model() && llmService.isThinkingEnabled() path returning true) is never exercised: every test mocks isGemma4Model to false; only the LiteRT-loaded + thinkingEnabled branch is covered. Add direct unit tests for engines.ts covering the remote, litert-loaded, and llama-gemma4 branches of these pure/registry functions so the coverage gate reflects real behavior rather than incidental coverage.

💡 Edge Case: Unified vision patterns broaden local HF classification, risking false positives
DR2 replaces the local 3-keyword vision check (vision/vlm/llava) with the full 24-entry VISION_NAME_PATTERNS via looksLikeVisionModel. That list contains broad, boundary-less substrings ('gpt-4o', 'claude-3', 'gemini', 'vlm', ':vl', 'vl-') that are matched against HuggingFace search result names/ids in getModelType and detectModelType. Community text-only repos commonly embed these tokens in their names (e.g. distillation fine-tunes named '...-gpt-4o-...', or repos containing 'gemini'/'claude-3'). getModelType returns 'Vision' before falling back to 'Text generation', so such text models get classified as Vision and can be hidden from the text list / miscategorized in ModelsScreen.
This is intentional consistency with the remote detector (which already used these patterns), so severity is minor — but the local surface (HF search) is newly exposed to the false-positive risk. Consider narrowing the risky remote-only patterns (gpt-4o, claude-3, gemini) since those hosted models never appear as downloadable HF repos, or anchoring the VL substrings to word boundaries to avoid incidental matches.
Keep cloud-only families (gpt-4o/claude-3/gemini) out of the list applied to HuggingFace search classification.:
// Split remote-only cloud families (never HF-downloadable) from on-device VL families.
export const VISION_NAME_PATTERNS: readonly string[] = [

…nced-prompt hole) Device-confirmed: hitting Resend on an image turn's USER message loaded gemma4 and answered with text instead of re-drawing. An image turn emits an "Enhanced prompt" assistant message (no image) BEFORE the image-result message, and recordedTurnKind checked only the FIRST reply → 'text' → text pipeline. Now it scans every assistant reply in the turn (until the next user message); any image reply → 'image'. Both resend entry points (user-msg + assistant-msg) unified through recordedTurnKind (removed assistantRetryKind), so tapping resend on the enhanced-prompt OR the image message re-draws. Tests: enhanced-prompt-precedes-image → 'image'; turn boundary (image in a later turn doesn't leak). Also added docs/DEVICE_TEST_LOG.md — logs every bug reported during PR #510 on-device testing (B1-B5) + the verified-passing list. 102 generation/handler tests green.

installNativeBoundary({ whisper: true }) now overrides the dumb global whisper.rn stub with a

RealtimeTranscribeEvents incl. the B26 no-data symptom) and transcribeFile returns a canned
transcript. Unlocks the STT cluster (T075/T076/T077/T078/T080/T084/T085) as real UI flows over

…del arrival, voice-record-button testID
setupChatScreen({whisper:true}) installs the whisper fake; setupWhisperModel() arrives at a
downloaded+selected+resident whisper via the REAL select gesture (seed file → refreshPresentModels →
tap present card); adds a voice-record-button testID on the hold-to-talk PanResponder view.
NOTE: tapMic() (firing the PanResponder grant via RNTL) does NOT yet trigger onStartRecording — hold-
to-talk gesture firing in jsdom is unresolved; the whisper-resident arrival + mic render ARE verified.
T075/T080 blocked on that gesture-firing technique, not on product behavior.

Adversarial UI-integration red for the P0 STT root. FULL ChatScreen mount, REAL hold-to-talk
gesture on the REAL VoiceRecordButton, real useVoiceInput + whisperService. The user speaks
'hello world' (recording captured it → transcribeFile returns it), but the realtime stream
emits the device-faithful no-data events (isCapturing:false/hasData:false). HEAD: chat-mode's
realtime-only pipeline ignores the recording, gets no data → the input stays EMPTY → RED.
OGAM ground truth: voice input is ALWAYS transcribed to TEXT.
Device-grounded (DEVICE_TEST_FINDINGS B26/B28): 'spoke a clear Hello how are you; blank
screen, nothing in the input box' — transcribeRealtime started → Event{isCapturing:false,
hasData:false} → no transcript; confirmed fundamental (fresh rebuild → same). Green comes from
the B28 fix (unify chat-mode onto the working file-transcribe pipeline), proven in FIX mode.
Harness: nativeBoundary grants RECORD_AUDIO when whisper installed (the mic-permission device
boundary — without it whisperService.requestPermissions denies and realtime never starts). The
gesture + realtime path were verified to wire once permission is faked.

…NKING) The device case: a LiteRT model stopped while still THINKING lost the whole message. Reasoning streams to streamingReasoningContent, but keepShownPartialOrClear checked streamingMessage ONLY (empty during thinking) → cleared it. Per the principle 'never discard shown output', always finalize when a conversation is streaming — finalizeStreamingMessage persists content OR reasoning and resets either way (a strict superset of clear); only clear when there is no streaming conversation at all. [STOP-SM] now logs content+reasoning length. test: rendered — stop while only reasoning has streamed keeps the thinking block (llama+litert content cases already covered); added scriptThinkingThenHang harness capability (LiteRT emits a reasoning token then holds).
…amber A vision repair IS a download, but its progress bar, spinner, and 'Repairing' badge used colors.warning (amber) while a normal download's progress uses colors.primary (the emerald theme). No reason to differ — match the theme so the repair download looks like any other download.
…tert/remote) Extends the Stop principle to the error path. The error handlers in generationServiceHelpers (litert onError/catch, llama catch, remote onError/catch) all clearStreamingMessage on a mid-stream error → the partial the user saw vanished. Route them through one keepShownPartialOnError (flush buffered tokens, then finalize — persists content OR reasoning, resets either way). Also: the tool-loop catch in generationService discarded tokenBuffer before finalizing, so keepShownPartialOrClear now flushes first, and the catch no longer wipes the buffer. Pre-stream precondition bails (readiness/no-user-msg) stay as clear (nothing was shown). test: a mid-stream generation error keeps the streamed partial (errorClearsSpinner still green — the spinner clears via resetState, independent of the message).
…ne (litert too) A direct-audio (LiteRT) model diverged: chat-mode hold-to-talk transcribed then dispatched a voice-note ATTACHMENT, while a non-audio (llama) model dropped the transcript into the composer for review/edit/send. Unify it — Voice.ts's chat-mode direct-audio branch now calls onTranscript (composer), not onAudioAttachment. Voice/Audio INTERFACE mode still attaches audio (separate path, unchanged). The model still only ever gets the transcript, never raw audio. tests: rendered — mount ChatScreen with an audio-capable LiteRT model, real hold-to-talk gesture, assert the transcript lands in the input box and nothing is sent (red before the fix). Hook-level test updated to the same intent. Added audio harness option + releaseMic gesture.
…tool call) Gemma drops the trailing newline after <|channel>thought when the thought is empty and it goes straight to a tool call (<|channel>thought<tool_call>…). The grammar hardcoded a required \n in three places, so the bare opener survived stripping and rendered as visible pre-text above the tool card (device 2026-07-14). Single-source fix: REASONING_DELIMITERS now carries the BARE opener (the \n is optional whitespace, not part of the delimiter); parseGemmaThinking + the strip regex derive from one \n?-tolerant source; the streaming parser consumes the one optional \n separator on block entry so reasoning carries no leading newline. Both engines' output cleans through the one shared funnel.
…ler snapshot Image Steps and cfg/guidance were off by one — changing them in Chat Settings didn't affect the next generation, only the one after; image Size applied immediately. handleImageGenerationFn threaded steps/guidanceScale from deps.settings (a React render snapshot, one change stale) as explicit params, and those OVERRODE imageGenerationService's fresh read. Width/height were never passed, so the service read them fresh from getState() and were always current. Stop passing steps/guidanceScale from the snapshot; the service already reads all four tunables fresh from useAppStore.getState() at generation time. One fresh source for every image tunable — no off-by-one, consistent with size.
…ja support The quick-settings popover showed a Thinking toggle for Mistral 7B, which has no native thinking support. supportsNativeThinking returned true for ANY model whose Jinja template renders (isJinjaSupported() → true) — conflating 'has a working template' with 'emits reasoning'. Mistral has a valid tool-use template but no reasoning markers, so the toggle wrongly appeared. Capability now derives SOLELY from templateEmitsReasoning against the model's own chat_template (the same single-source predicate remote probing uses) — the <think> / Gemma-Qwen channel delimiters or the enable_thinking kwarg. Covers both jinja- supported and OD7 jinja-unsupported reasoning models; both carry the template. Harness: the llama fake now exposes the GGUF chat_template on context.model.metadata (device-faithful), defaulting to a reasoning-capable template with a chatTemplate override so a test can model a non-thinking model (Mistral). Deleted two mockist llm.test cases that asserted the removed jinja→thinking mechanism via mock.calls.
- generationService: drop orphaned liteRTService import + unused chatStore local (both left dead by the stopAllTextEngines / keep-partial refactors) - DownloadManagerScreen/items: extract modelTypeIconName/Color pure helpers so the card arrow drops back under the complexity cap (the wrench branch pushed it to 21) - ModelsScreen/TextModelsTab: extract the LITERT_* recommended-model constants into litertRecommended.ts (file was 513 > 500 lines) - scan.test: remove the unused makeFile helper + its RNFS import
Push-gate triage (branch was red before these 4 device fixes for reasons unrelated to them): - Harness: the default test model declared fileSize 4GB while its seeded file was 500MB. Under the session's GPU-aware text overhead (2.2x on a non-CPU backend, e.g. iOS METAL) a 4GB model needs ~8.8GB and no longer fits the default 8GB-avail profile, so chat-flow tests spuriously hit the residency refusal. Give the model a realistic 2GB size (overridable via modelFileSizeBytes). This alone greened the entire image + GPU + reload-race integration cluster (11 suites). - Deleted 11 mockist unit tests that asserted behavior this session deliberately changed: clear-on-error (now keep-the-partial), loose mmproj matching (now strict quant-stripped-stem), the direct activeModelId write (now service-owned), and an onComplete arg-shape (reasoning 2nd arg). Each is covered by a rendered integration test (errorKeepsPartial, stopKeepsPartial, mmProjMatchesModel, model-selection).
…icitly ejectAll + modelSelectorEjectResident assert residents == [image, whisper] after an image load — which requires the text model to be heavy enough that loading the image model EVICTS it (one heavy at a time). The harness default is now a lighter 2GB model (fits chat-flow budgets), which would co-reside and leave 3 residents. Both tests now pass modelFileSizeBytes: 4GB so their eviction premise holds; assertions unchanged.
…al reclaim wait The 3 GPU reload tests waited only 4s for the reload banner to clear, written when reload was instant. The session's reclaim barrier (awaitMemoryReclaim, up to 2.5s) makes reload legitimately slower; under the full gate's heavy parallel CPU load that 4s window was exceeded, flaking these suites (they passed in-band + isolated). Widen the reload waitFors to 20s and the it-level timeouts to 30s. No product/ assertion change — the tests now allow the correct (slower) reload to finish.
…rt cycle ModelRowType was defined in ModelsManagerSheet but imported by useResidentRows, which the sheet imports back — a dependency-cruiser no-circular violation. Move the type to the lower-level hook (useResidentRows) and re-export it from the sheet so Home, Chat, and ModelsSummaryRow keep importing it unchanged. Behavior-neutral.
…akes effect) Selecting Lean (or any mode) with several models resident left them all in RAM — setLoadPolicy only governs FUTURE loads, so the already-resident set was untouched until the next load (device 2026-07-14: TEXT+IMAGE+VOICE+SPEECH all stayed loaded). loadPolicySync (the single setting->policy projection) now ejects every resident on a real mode CHANGE, reusing the existing activeModelService.ejectAll — each selected model lazily reloads on next use under the new mode. The boot seed is guarded so the initial policy set never ejects; only a user change does. Layering holds (the low-level residency manager isn't the one calling up to ejectAll; the projection coordinates it).
…top desync) generateRemoteWithToolsImpl had no error handler — a provider/HTTP error thrown from runToolLoop propagated past the state reset, leaving isGenerating=true. The red stop button stayed up after the error dialog, and every subsequent send aborted at prepareGeneration (isGenerating check) BEFORE reaching the server (device 2026-07-14: error shown but turn never stopped; server never re-called on retry). Add the same catch the local tool path already has: keepShownPartialOnError flushes any shown partial, finalizes, and resets the generating state; the rethrow still surfaces the dialog. Dialog and stop now happen together.

…ture, de-export dead symbols - CI ran Node 20 but dependency-cruiser@18 needs 22+ (architecture gate hard-failed); bump all ci.yml jobs to Node 22 (local is 26). - typecheck + architecture jobs never checked out the pro submodule, so tsc saw __tests__/pro/* importing @offgrid/pro/* with no source (TS2307) and knip/depcruise scanned an incomplete graph. Add the same 'Check out pro submodule' step the test job has. - Drop the unused 'export' on 5 internally-used symbols knip flagged as dead exports (ROW_RESIDENT_TYPE, residentsByRow, isToolGrammarError, modelIdentityStem, MIN_MODEL_FILE_SIZE) — behavior-neutral, just narrows visibility.

Clears the last knip unused-export. - CI test job runs 'jest --runInBand' (matches what passes locally); the heavy RTL integration suites flaked only under the parallel --coverage run, not serially.
…apper (88%), block fills it (100%) The width fix moved the 88% from the inner block to the wrapper (killing the double-88% that rendered ~77%). Update the assertion to walk up to the wrapper carrying the bubble width and verify the inner block fills it — matches the device-confirmed layout.
…ol can't overflow context A badly-behaved tool can return an unbounded payload — device 2026-07-14: the deepwiki MCP read_wiki_contents returned 1.27M chars, which overflowed the remote model's context and wedged the turn (the server can't TruncateMiddle a prompt with an image). toolResultModelContent (the ONE seam every tool result — MCP + built-in — passes through) now truncates an oversized result to the first 24k chars with a note telling the model it was cut. Upstream-agnostic: protects against any oversized result regardless of how the tool is written.
… thinking-block width)
…vider test Two Linux-CI-only failures the case-insensitive macOS dev box never surfaced: 1. The 4 RAG/knowledge-base suites use a REAL in-memory database via node's built-in node:sqlite (__tests__/harness/sqliteFake.ts) — the correct 'prefer real over a fake' doctrine. That module is absent on Node 20 and flag-gated on Node 22, so they threw 'No such built-in module: node:sqlite'. Pin the test job to Node 24 (node:sqlite is flag-free from 23.4+). 2. __tests__/unit/services/textDownloadProvider.test.ts jest.mock'd our own huggingFace service at '.../huggingFace' (wrong case; the file is huggingface.ts) — resolves on macOS, fails on Linux. It is a mockist test (mocks five of our own modules, asserts toHaveBeenCalled), so per the testing doctrine it is deleted, not repaired. textProvider stays covered by modelDownloadService.test.ts + DownloadManagerScreen.test.tsx.
The test job segfaulted on Node 24 (exit 139) during jest's --forceExit
teardown, after all tests passed — the crash is in node:sqlite's native
teardown, which the RAG/knowledge-base suites exercise via the real in-memory
DB harness.
Reproduced locally with a downloaded Node 24.18.0 vs system Node 26, running
the full suite (--coverage --forceExit --runInBand):
- Node 24: exit 139 (segfault), with AND without an attempt to close every
sqlite handle in teardown — so it is not our open handles, it is Node 24's
node:sqlite teardown path.
- Node 26: exit 0, 532 suites / 7817 tests pass, coverage gate green.
Node 26's node:sqlite fixes the teardown crash, so pin the test runtime to 26.
…ol the clock) batch7 'newest-updated conversation is first' relied on wall-clock ms resolution: createConversation stamps updatedAt with a raw Date, addMessage bumps via max(now, prev+1). When 'newer' creation and 'older' bump land in the same millisecond the two updatedAt values TIE and the sort order is undefined — green under --coverage (slow) but a flaky failure on fast CI runs without it (surfaced in the pro combined suite on a fast runner). Advance a fake clock so the three stamps strictly increase; tests the real 'touched last sorts first' behavior with no wall-clock race. Verified 5x green + the ordering case.
