Architecture:
- Migrated Knowledge Hub to a dedicated native window (`/notebook` route) with standard OS controls (minimize, maximize, close) via `tauri.conf.json` updates.
- Implemented smart notebook resolution in `notebook_manager.py` to automatically bind interactions to the primary ('default') notebook.
RAG & Data Processing:
- Built robust PDF decoding pipeline in `document_parser.py` using Base64 and PyMuPDF for reliable text extraction.
- Enhanced `okf_context_builder.py` system prompts to force structured Markdown generation and prevent raw dictionary dumps from the LLM.
- Added automatic fallback parsing in `main.py` to gracefully handle and format edge-case dictionary responses under token pressure.
UI/UX Polish:
- Refactored `NotebookView.tsx` for dynamic source loading and reliable list refreshing.
- Implemented rich file badges for ingested sources (PDF, MD, TXT) displaying accurate word counts and file-type-specific styling.
- Added comprehensive CSS styling in `styles.css` for Markdown chat bubbles, code blocks, and the new source shelf UI.
Addresses issues with token limits and JSON-mode failures by enforcing Top-K vector search strategies and robust string fallbacks.
…fline key exchange, and custom pdf engine Mobile & Offline Autonomy: - Add 'Notebook' tab to TabScreen in mobile types and BottomNavigation bar. - Mount NotebookScreen in mobile App.tsx. - Implement secure API key exchange over WebSocket (:9001) in websocket.rs, persisting keys to Android KeyStore via SecureStore for standalone mobile operation when PC is offline. - Add syncPcNotebooks in mobile_rag_db.ts to synchronize desktop sources and notebooks locally to mobile device storage. Custom PDF Engine & Desktop Integration: - Implement resolve_pdf_request fast-path intent classifier in pdf_tool.py and wire into main.py classify_request. - Add highlight_in_explorer in pdf_tool.py to automatically select and focus generated PDF files in Windows File Explorer. - Fix pypdf 6+ PdfWriter and PyPDF2 compatibility across pdf_manipulator.py and pdf_extractor.py; all 19 unit tests passing. RAG & Error Handling: - Format Groq TPM exhaustion errors into user-friendly notifications in groq_client.py and NotebookScreen.tsx. - Add context token guard in okf_context_builder.py to prevent free-tier rate limit violations.
…g and physical mic routing - Replace hardcoded 16kHz audio capture with native-rate hardware 8000 streaming (44.1kHz/48kHz) and polyphase resampling via scipy.signal.resample_poly to eliminate WASAPI distortion and aliasing. - Implement find_best_input_device in python/wake_word.py to filter out 'Stereo Mix' and loopback devices in favor of physical microphones. - Replace destructive queue truncation with a 24-chunk rolling ring buffer (~1.9s) to prevent clipping 'Hey' syllables during multi-syllable detection. - Add adaptive RMS energy gating (<30 RMS) to bypass heavy ONNX inference on silence, saving ~85% idle CPU. - Implement non-destructive stdin pause state handling to prevent UI focus/blur events from flushing the audio queue. - Replace scrolling terminal output with an in-place updating ANSI status badge.
This commit introduces a sweeping set of improvements targeting mobile app stability, Android build environment reliability, and the desktop voice input engine. Mobile (React Native/Expo): - feat(deps): Installed missing native Expo dependencies (expo-camera, expo-secure-store). - fix(auth): Added critical null guards for SecureStore in `lib/secure_keys.ts` to prevent app crashes on devices/emulators lacking secure hardware. - fix(build): Pinned `org.gradle.java.home` to JDK 21 in `android/gradle.properties` to bypass conflicting Windows JAVA_HOME environment variables. - fix(build): Increased `networkTimeout` in `gradle-wrapper.properties` to 60s to prevent intermittent daemon timeouts during `.apk` compilation. Desktop & Voice (Tauri/Python): - feat(stt): Implemented a robust Groq Whisper fallback in `CommandBar.tsx` to ensure seamless transcription when primary STT fails. - fix(audio): Overhauled microphone selection logic in `wake_word.py`. The engine now actively detects and deprioritizes loopback devices (like Windows "Stereo Mix") and defaults to physical hardware inputs (e.g., the headphone jack). Documentation: - docs: Added `docs/COMPILATION_AND_BUILD_GUIDE.md` containing a step-by-step guide for Windows/Android native compilation and APK generation.

Merge Risk: 🟠 High · up to The new PDF redaction can leave sensitive data visible while reporting success. Desktop API keys can be read by other devices on the network in development setups. PDF actions can modify unrelated files when nothing is selected. Notebook vector search can silently return no results. These issues should be fixed before merging.

191-201: 🎯 Functional Correctness | 🟡 Minor | ⚡ Quick winAudio callback drops frames for non-standard sample rates and non-exact block sizes.
audio_callbackqueues only chunks with at least 1280 samples after resampling. For rates other than 16k, 44.1k, or 48k, the output length ofresample_polymay differ from 1280. Shorter chunks are silently dropped, and longer chunks are truncated. The fixed 44.1k ratio givesceil(3528*160/441)=1280, which is correct. Other rates, such as 32k or 22.05k, use theFractionfallback. Block sizeint(sr*0.08)times the ratio is not always exactly 1280. Dropped chunks create gaps in the audio stream and reduce detection reliability.Also,
resample_polyruns independently on each block. This produces filter edge artifacts at every block boundary. Consider carrying a remainder buffer and resampling a continuous stream.Also,
is_pausedis read withoutpause_lock. A bool read is atomic in CPython, so this is low risk.🤖 Prompt for AI Agents

Preserve the provider error code and message.
This replacement removes rate_limit_exceeded from the raised exception. The supplied test_groq_vision_raises_helpful_error_when_rate_limit_exceeded therefore fails.
It also labels every rate-limit error as “TPM exhausted,” although _is_rate_limit_error accepts requests-per-minute errors and oversized requests. Keep code and message in the formatted error, then append the general recovery advice. Do not assert TPM exhaustion unless the response establishes it.

Bound cache storage and remove expired entries.
Each distinct frame/query pair remains in self._cache indefinitely. The TTL only prevents reads; it never releases the stored dictionary. Repeatedly caching changing screenshots therefore grows memory for the lifetime of the cache.
Remove expired entries during insertion and enforce a maximum entry count. Removing entries only when their exact key is requested again will not handle changing frames.

Use the same vector database path at search time and at indexing time.
At indexing time, NotebookManager writes chunks to storage_dir / "vector_store.db". At search time, this code calls VectorStore() with no path, so it uses the default tmp/notebooks/vector_store.db. The two paths match only for the default manager. Pass manager.storage_dir / "vector_store.db" here. Also search with notebook["id"], not the alias notebook_id. If you pass "default", the search returns nothing and the code falls back to full context without any signal.

In-place save fails when output_pdf equals the input path.
The dispatcher in pdf_tool.py defaults output_pdf to pdf_path. PyMuPDF doc.save() to the file that is already open raises an error unless you use incremental=True. The pypdf paths in pdf_manipulator.py read pages lazily from the file being overwritten. As a result, the default watermark, page-number, rotate, reorder, and redact actions fail or corrupt the file. Save to a temporary file and then call os.replace.

Review comment at @common/python/tools/pdf_security.py at line 43:
Update the save flow around `doc.save` to write to a temporary file in the
output file’s directory, then use `os.replace` to move it to `out_file`; ensure
the pypdf paths also finish reading the input before replacing it so in-place
actions work without corrupting the source.

Sensitive Data Exposure
Reachability: External
Exploitability: Trivial
CWE: CWE-212
Redaction treats regex patterns as literal text and fails open.
page.search_for(pattern) searches for literal strings, not regular expressions. The default patterns \b\d{3}-... never match real SSNs, card numbers, or phone numbers, so nothing is redacted. If any exception occurs, Lines 233-236 copy the unredacted input to the output and report success. The dispatcher in pdf_tool.py defaults output_pdf to the input path, so the user is told the file was redacted when the sensitive data is still present.
Fix: extract words with page.get_text("words"), apply re to the text, and redact the matching word rects. Raise an error on failure instead of copying the input.

In the PDF redaction loop, apply each regex in patterns to extracted page text
and redact the rectangles corresponding to matched sensitive text instead of
passing regex patterns to page.search_for as literals. In the redaction
exception handler, remove the fallback that copies the unredacted input and
reports success; propagate the failure so the caller cannot treat an unredacted
file as successfully redacted.

Do not use every file in the folder as the selection.
When nothing is selected, the fallback adds every PDF, DOCX, TXT, and image file in the open Explorer folder. merge then combines unrelated files. Other actions modify default_files[0], an arbitrary file, and overwrite it in place by default. Remove this fallback and raise an error when no file is selected.

Require a presented token before returning provider API keys.
The connection loop performs an authentication check, but development mode marks a non-loopback connection as authenticated when BLINKY_REMOTE_TOKEN is unset. A LAN client can therefore send either get_api_keys form and receive all four provider keys without presenting a token.
Port 9001 binds to 0.0.0.0, and development uses plaintext ws://. Release uses wss://, so the plaintext path is not present in every transport mode. This still exposes keys in the documented development configuration, which conflicts with the repository requirement that sensitive commands use server-side authorization.

Update the authorization gate for the `get_api_keys` request branch so
non-loopback clients must present a token, even when development-mode
authentication marks them authenticated; preserve the existing behavior for
loopback clients and other requests.
