+
+parakeet-rs (altunenes) DOES have a genuine incremental streaming decode API for Parakeet-family models: ParakeetEOU and Nemotron structs thread real recurrent state between calls internally (EncoderCache: cache_last_channel/cache_last_time/cache_last_channel_len; decoder LSTM state_h/state_c; last_token) plus a 4s rolling audio ring buffer, so callers just feed sequential small chunks (160ms for EOU, 560ms for Nemotron) and get incremental partial text -- it is not naive re-chunking of a batch decoder. Source: github.com/altunenes/parakeet-rs src/parakeet_eou.rs and model_eou.rs, examples/streaming.rs (checked 2026-07-02).

+WhispAssist app icon/branding: real logo provided by user (paperclip mascot + purple speech-bubble-with-sparkles mark, WhispAssist wordmark). The app icon (title bar/taskbar/tray/installer) is cropped from just the small speech-bubble-with-sparkles mark, not the full marketing graphic or the paperclip mascot (too much fine detail to read at 16-32px). Updated twice: first a transparent-background crop, then a refined version on its own gradient purple background from a cleaner logo revision the user provided. Regenerated via ; that command generates iOS/Android/Appx/macOS outputs by default which must be deleted since WhispAssist is Windows-only (not referenced by tauri.conf.json). tray.png is a manual 32x32 export, not one of tauri icon's own output names.

+
+The EOU streaming variant used by parakeet-rs is a genuinely separate ONNX export, not a mode of the batch Parakeet TDT model: it's NVIDIA's own nvidia/parakeet_realtime_eou_120m-v1 (120M params, cache-aware FastConformer encoder + LSTM decoder, 80-160ms chunks, English-only, no punctuation/casing, emits <EOU> token). This is distinct from istupakov/parakeet-tdt-0.6b-v3-onnx (600M, the community ONNX conversion used for WhispAssist's originally-considered batch/full-file transcription path, which has the ~4-5min length limit). Both are downloaded separately; author's own code comment on reset_on_eou says 'I must admit that this is not work very well on my real world tests'.

+M4.4 (MS Graph calendar source, T8.9, FR-CAL-6) SHIPPED 2026-07-07 on branch feature_chore_bug_005 (commits 83cb30e..7df76df + 1cf0be1). This LIFTS the 2026-07-02 'T8.9 on hold' decision — user explicitly asked to build it in this session, overriding the earlier hold. Implementation: calendar::GraphSource implementing CalendarSource, reusing sync::oauth's provider-agnostic PKCE/loopback machinery (added a 'graph-calendar' OAuth provider entry, made sync::resolve_access_token pub(crate) for cross-module reuse) rather than building new OAuth plumbing. This completes all of milestone M4 (M4.1 chunked upload, M4.2 multi-language, M4.3 Dropbox/Box, M4.4 Graph calendar).

+WhispAssist GPU acceleration decision (2026-07): whisper.cpp GPU transcription via VULKAN as primary cross-vendor path — ONE binary covers NVIDIA+AMD+Intel (whisper-rs 'vulkan' feature). whisper-rs GPU features: cuda (NVIDIA-only, CUDA toolkit at build), vulkan (cross-vendor, Vulkan SDK at build + vulkan-1.dll loader shipping with every GPU driver), hipblas (AMD/ROCm LINUX-ONLY, unusable on Windows), metal (Apple). KEY: whisper.cpp GPU backends are COMPILE-TIME/static (cannot download runtime on-demand like the ort load-dynamic NPU path); binary must be built with the feature. Vulkan is default GPU build; CUDA is optional NVIDIA-only turbo variant LATER (user: 'we will do cuda later'). Vulkan degrades to CPU if no GPU present.

+
+In WhispAssist's calendar module, CalendarSource::import() is a synchronous trait method (matches PstSource's blocking subprocess call). GraphSource (MS Graph, async reqwest HTTP) bridges into that sync signature via tauri::async_runtime::block_on inside fetch_events, and callers run the whole import() call inside tauri::async_runtime::spawn_blocking (same pattern commands.rs already used for PstSource's readpst subprocess) — avoids making CalendarSource async just for one source. Kept a separate WA_GRAPH_CALENDAR_BASE_URL env var (distinct from sync's WA_GRAPH_BASE_URL used by OneDriveTarget) so calendar and sync tests never race on the same process-global env var in cargo test.

+
+WhispAssist PST usability fixes (2026-07-06, commits 00de9d3/9d757be/75ec24d): (1) calendar path is now remembered in Settings (pst_last_path field) so the user doesn't re-browse every launch; (2) added an opt-in 'auto-sync on launch' checkbox (pst_auto_sync) that re-imports the remembered path once at startup - deliberately a ONE-SHOT pass mirroring the existing sync-job-resume pattern in lib.rs, NOT a periodic timer, because NFR-RES-1 ('no polling timers when idle') is enforced consistently everywhere else in this codebase (every startup task has a comment noting this). User asked about a periodic 'read frequency' option too; I declined to build that specific piece and explained the NFR-RES-1 conflict rather than silently building or silently dropping it.

+
+WhispAssist M1 feature-briefs decomposition (2026-07-06, docs-only, branch feature_chore_bug_004). KEY INSIGHT: M1 is heavily scaffolded already, do NOT re-create — IPC types FeatureBrief/FeatureBriefInfo/ContextExcerpt (models.rs), api.ts bindings createFeatureBrief/listFeatureBriefs/getFeatureBrief/setBriefExposed, the 4 commands registered in lib.rs, DB tables feature_briefs + mcp_access_log (migrations/0003_ai_mcp.sql), the briefs/<id>.json schema (docs/03-data-model.md), and the FeatureBriefBuilder trait (docs/04-api-contracts.md) ALL EXIST; only the 4 command bodies return not_implemented(). REMAINING to build: (1) Store methods insert_feature_brief/list_feature_briefs/get_feature_brief_row/set_brief_exposed; (2) a new non-streaming LlmProvider::complete(system,user)->String primitive (mirrors suggest_tags; impl Ollama+OpenAiCompat, Anthropic later); (3) FeatureBriefBuilder in a new briefs module (strict '## Title/## Problem/## Desired Outcome/## Acceptance Criteria' prompt like RESPONSE_FORMAT_INSTRUCTIONS + parse_brief mirroring parse_summary); (4) the 4 command bodies (add state: State<AppState>, Tauri injects it, api.ts unchanged); (5) UI in SummaryPanel; (6) golden-transcript tests. KEY DESIGN DECISIONS: context_excerpts are VERBATIM transcript substrings (grounding invariant enforced by the golden test), selected by keyword overlap, NOT model paraphrase; the on-disk file is a sealed BriefFile envelope {schema,generated_at,provider,model,...fields,source} indexed by the feature_briefs table (file=truth, row=index); write file+row only AFTER a successful distill (no partial artifacts on LLM failure).

+### Decision: NOT pursuing NVIDIA Parakeet or DirectML...
+
+Decision: NOT pursuing NVIDIA Parakeet or DirectML/NPU acceleration for WhispAssist transcription near-term, as of 2026-07-02. Researched achetronic/parakeet (Go, Linux-only, dead end) and altunenes/parakeet-rs (Rust, built on ort, has genuine streaming via a separate EOU 120M model with real internally-threaded encoder cache and LSTM decoder state). Reasons not to pursue now: (1) DirectML support for this model family is unproven - zero reports of anyone running it, and there is a live unresolved ONNX Runtime bug (microsoft/onnxruntime issue 19837) producing wrong output on DirectML for the exact LSTM+Einsum op combination these models use; (2) DirectML itself is now in Microsoft maintenance mode, with new NPU/GPU work moving to Windows ML instead, which calls WhispAssist's existing ADR-0004 (ort + DirectML for NPU) into question independent of Parakeet; (3) Parakeet streaming needs a continuous per-meeting state machine fed small sequential chunks, fundamentally incompatible with WhispAssist's current stateless independent 4-second-window architecture - a real rearchitecture, not a swap, and it would lose whisper.cpp's crash-recoverable-per-window property; (4) competitor Meetily does not actually do live Parakeet+hardware-acceleration either - they only use it for offline batch re-transcription. Recommended future path if revisited: CPU-only Parakeet-EOU streaming spike first to validate the rearchitecture and quality tradeoffs (EOU is English-only, no punctuation/capitalization), treat NPU acceleration as a separate track that should probably target Windows ML rather than raw DirectML.

+
+WhispAssist CUDA + AMD-non-Vulkan acceleration PLAN (2026-07-05): whisper.cpp bakes in exactly ONE GPU backend at compile time. Universal build=Vulkan (all vendors). NEW: NVIDIA-turbo installer variant = whisper.cpp CUDA (feature already declared Cargo.toml:94) — but a CUDA build has NO Vulkan, so AMD/Intel GPUs in that variant need a non-Vulkan accel path. DECISION (recommended, user was away/didn't confirm): AMD-non-Vulkan = DirectML via the EXISTING ort/ONNX NPU path (OnnxNpuTranscriber generalized to accept EP: OpenVINO-NPU vs DirectML-GPU+device_id). DirectML works on any DX12 GPU, load-dynamic (no new build toolchain), one binary, degrades to CPU. hipBLAS/ROCm DEFERRED (narrow gfx coverage, fragile on Windows, needs 3rd installer). CORE CODE CHANGE: add AccelPath enum {WhisperCuda,WhisperVulkan,WhisperCpu,OnnxOpenVino,OnnxDirectML} + resolver in hardware/mod.rs from (BackendId+cfg!(feature)+runtime readiness); transcriber factory switches on it. This also CLOSES the known detection-honesty gap (GPU marked available from DXGI regardless of compiled feature -> no-op GPU routing). PHASES: P0 detection-honesty+AccelPath (small, no hw, do first), P2 AMD/Intel DirectML (validate on Intel Arc iGPU locally), P1 CUDA (needs NVIDIA hw/CI). ort needs 'directml' feature + an onnxruntime.dll built with DML EP in the runtime bundle; DirectML.dll ships with Win10 1903+.

+
+WhispAssist NEXT STEPS — CPU transcription slowness testing round (open bug): the full transcribe_file path takes ~90s for a 6.3s clip on a 14-thread CPU with base.en (should be ~2-3s). This is PRE-EXISTING (predates Vulkan) and independent of the GPU work. To root-cause next: (a) verify whisper set_n_threads actually applies available_threads()=14 (log n_threads in run_full); (b) check whether the encoder pays full 1500 audio_ctx per 30s window even for a 6s clip in the non-streaming path (the streaming path fix in commit 8530a22 scaled audio_ctx by window length, but transcribe_file/run_full may not); (c) run stock whisper-cli directly on the same model+wav to isolate whether it's OUR run_full config vs whisper.cpp itself; (d) test greedy vs beam params and q5_1 vs f16 model; (e) confirm it's not thermal/throttle. The non-vulkan CPU baseline re-run (task, ~90s expected) was in progress to formally confirm parity with the vulkan build's CPU number.

+
+WhispAssist user working style (observed 2026-07-06): (1) Demands EMPIRICAL PROOF over theory. When I attributed silent new recordings to the mic-not-in-WAV design, they pushed back ('the old file is also vault-sealed and plays fine, so it must be the 32->16bit change'). Resolving it required an actual real-hardware loopback capture test (play a known sound, read peak i16 from the WAV) to prove the 16-bit path records real audio — only then accept the diagnosis. HOW TO APPLY: when diagnosing a bug, verify the cause with a runnable test/measurement and show the evidence; don't just assert a root cause. (2) Highly protective of encryption-at-rest. They independently spotted that the decrypted audio.play.wav on disk and the browser 'download' button undermined the vault, and asked to switch playback to in-memory on-the-fly decryption. HOW TO APPLY: proactively avoid writing plaintext of vault-sealed data to disk and close off easy exfiltration paths (downloads, temp files).

The shipped UNIVERSAL installer is built with: npm run tauri build -- --features vulkan --config src-tauri/tauri.vulkan.conf.json, with env VULKAN_SDK=C:\VulkanSDK\1.4.350.0, CMAKE_GENERATOR=Ninja, CARGO_TARGET_DIR=C:\wt, and vcvars64.bat loaded from 'C:\Program Files (x86)\Microsoft Visual Studio\2022\BuildTools\VC\Auxiliary\Build\vcvars64.bat'. Outputs land at C:\wt\release\bundle\msi\WhispAssist_<ver>_x64_en-US.msi and \nsis\WhispAssist_<ver>_x64-setup.exe (MSI ~44MB, NSIS ~9MB). The build does NOT create/push git tags — after merging to main, tag manually: git tag v<ver>; git push origin v<ver>. Last release before 0.2.0 was v0.1.6 (PR #15).

+
+Real libpst quirk found via a real 7.2GB mailbox test (2026-07-06): this readpst/libpst build joins a multi-value RRULE BYDAY with semicolons instead of RFC 5545's commas, e.g. 'RRULE:FREQ=WEEKLY;COUNT=10;BYDAY=MO;TU;WE;TH;FR' - so TU/WE/TH/FR appear as bare semicolon-separated tokens with no '='. A naive RRULE parser using '?' on split_once('=') silently bails out (returns None) for any event with more than one weekday, which is why the first version of expand_rrule worked for single-BYDAY series but silently dropped recurrence for multi-weekday ones. Fix: track the last-seen key and attribute a bare (no '=') token to it as a continuation value. This joins other already-documented libpst 0.6.63 quirks in ADR-0008 (no ORGANIZER/ATTENDEE emitted, no -8 flag support, wrong -t usage string).

Caveat: the FIRST COM activation of the mic can deliver 0 frames within the first ~600ms (cold start); a second run delivers normally. So a hardware mic smoke test should assert open+stop succeed (summary.sample_rate>0), not frames>0. Test: audio::tests::microphone_capture_opens_and_stops_cleanly (#[ignore], run with --ignored).

+
+CONFIRMED FIX for WhispAssist release build crashes: Windows Defender real-time scanning of src-tauri/target was corrupting rustc.exe's compilation (random STATUS_STACK_BUFFER_OVERRUN crashes on different crates each run). Adding Defender exclusions (Add-MpPreference -ExclusionPath for target/, ~/.cargo, ~/.rustup, and -ExclusionProcess for rustc.exe/cargo.exe) fixed it completely -- full release build (whisper-rs, sherpa-rs native deps, MSI+NSIS bundling) now succeeds cleanly with the project's normal aggressive release profile (opt-level=z, codegen-units=1, lto=true). No toolchain reinstall or profile change was needed after all; those were red herrings from earlier in the debugging session. Also: a leftover running whispassist.exe instance can block cargo from overwriting the binary with 'Access is denied' -- close it before rebuilding.

Also: memanto's on-prem backend (localhost:8080) needs Ollama (localhost:11434, embedding model nomic-embed-text) running for recall/export/sync to work, and the active agent session (memanto agent activate whispassist) can expire/drop mid-session — 'remember' can report success even when the write doesn't actually persist/index, so verify with 'memanto recall --recent' after a batch of remember calls rather than trusting the success message alone.

+WhispAssist runtime bundle URLs CORRECTED to gitea /media/ path (2026-07-06, commit 224aaf9): the .7z runtime bundles are hosted via Git LFS, and gitea's /raw/ endpoint returns the LFS POINTER (text) not the file, so the download URLs were changed from /raw/branch/main/ to /media/branch/main/ (gitea's media endpoint resolves LFS objects). Final URLs: NPU=https://git.dou.bet/iamdoubz/WhispAssist/media/branch/main/runtime/openvino.7z, DirectML=https://git.dou.bet/iamdoubz/WhispAssist/media/branch/main/runtime/directml.7z. SHAs unchanged (openvino ca0be9fc..., directml 34369222...). Files tracked via Git LFS (.gitattributes: runtime/*.7z filter=lfs). Still on branch chore_debug (no PR yet); URLs point at main so they resolve after merge. GOTCHA for future: GitHub raw.githubusercontent AND gitea /raw/ both serve LFS pointers not content — always use gitea /media/ (or GitHub media/LFS URL) for LFS-backed download targets.

+
+cargo test in WhispAssist src-tauri reliably crashes at LINK time (rustc.exe exit 0xc0000409 STATUS_STACK_BUFFER_OVERRUN) when linking the full debug test binary against whisper.cpp+sherpa-onnx native libs with full debug info (debuginfo=2 default for test profile). This reproduces even from a clean target/debug, with reduced --jobs, regardless of Defender exclusions (which fixed the earlier release-build crashes but not this). FIX: set env var CARGO_PROFILE_TEST_DEBUG=0 (drop debug info) before cargo test -- this shrinks the PDB/link footprint enough to avoid the crash. Confirmed working: 'cargo test privacy_self_check' passed cleanly with CARGO_PROFILE_TEST_DEBUG=0 --jobs 4. Also noted: commands.rs is NOT feature-gated for cpu-transcription/diarization (unconditionally imports SherpaDiarizer/WhisperTranscriber/run_streaming_worker), so cargo test --no-default-features fails to compile -- can't lighten the native-link footprint that way, must use the debug-info trick instead.

+
+WhispAssist dark-theme native-control gotcha (2026-07-06, commits 4442f80/8038918): the app theme is a MANUAL toggle (data-theme on html + .app), independent of the OS prefers-color-scheme. Native form controls default to LIGHT and render bright-white in dark mode. Fixes applied: (1) added CSS 'color-scheme: light' on :global(:root) and 'color-scheme: dark' on :global([data-theme="dark"]) in App.svelte — this alone fixed unstyled controls. (2) A <textarea> was white because Settings.svelte's 'input, select { background:var(--bg); color:var(--fg) }' rule EXCLUDED textarea; fix = add textarea to that selector. (3) The header template <select> (.theme-select) options popup stayed WHITE even with color-scheme:dark because it had 'background: transparent' — an AUTHOR-styled select makes Chromium/WebView2 render its options popup in light unless the options carry their own colors. Fix = give .theme-select an explicit 'background: var(--bg-elevated)' AND style '.theme-select option { background: var(--bg-elevated); color: var(--fg) }'. LESSON: for dark-mode selects, set color-scheme on the root AND author the <option> background/color with theme tokens; don't rely on transparent backgrounds.

+WhispAssist test-environment quirk found 2026-07-06: wasapi::get_default_device(&Direction::Render) (and thus find_render_device(None)) FAILS when called from within 'cargo test' on this dev machine, even though the real desktop app (running as a normal foreground GUI process) resolves it fine. Enumeration itself (DeviceCollection) works fine in both contexts -- it's specifically the 'default device' role query that needs a real interactive audio session. Tests for this were written to assert consistency (find_render_device(None) vs a raw wasapi::get_default_device call, or unknown-id fallback vs None) rather than assuming a default device is resolvable, so they pass in both environments. Implication: don't trust 'cargo test' alone to validate anything touching wasapi's default-device APIs -- verify audio-device-selection behavior via the actual running app instead.

Recipe: (1) ORT_DYLIB_PATH -> site-packages/onnxruntime/capi/onnxruntime.dll (the OpenVINO-enabled ORT build); (2) prepend BOTH openvino/libs AND onnxruntime/capi to PATH so dependent DLLs (openvino.dll, onnxruntime_providers_openvino.dll, onnxruntime_providers_shared.dll) resolve; (3) OpenVINOExecutionProvider::default().with_device_type("NPU").build().error_on_failure() to make a failed NPU registration LOUD instead of silently falling back to CPU; (4) Session::run needs &mut session. For shipping, bundle these DLLs with the Tauri app (resource/sidecar) instead of relying on pip. load-dynamic means no C++/OpenVINO build step in cargo.

+
+DirectML support in parakeet-rs for NVIDIA Parakeet/EOU/Nemotron models is purely theoretical/unvalidated, not a proven working combination. Evidence: (1) parakeet-rs's own Cargo.toml/execution.rs just forwards to ort's generic directml feature with zero model-specific notes -- contrast with its explicit CoreML warning ('CoreML EP currently runs slower than CPU for Sortformer/Parakeet models because the ONNX graphs have dynamic input shapes'); no equivalent DirectML note exists. (2) Searched all 113 issues in altunenes/parakeet-rs GitHub repo: zero mention DirectML. (3) microsoft/onnxruntime issue #19837 (opened 2024, still unresolved as of check) reports DirectML EP producing wrong numeric results on a model containing LSTM+Einsum ops -- root cause never found. (4) Microsoft's own microsoft/DirectML GitHub repo now carries a banner: DirectML is in maintenance/sustained-engineering mode, with new feature development moved to Windows ML (WinML); relevant since WhispAssist ADR-0004 specifies ort+DirectML for NPU accel. Recommend flagging ADR-0004 for review given this shift.

+Root cause of WhispAssist release build crashes found: NOT toolchain corruption. rustc.exe crashes with STATUS_STACK_BUFFER_OVERRUN (0xc0000409) specifically compiling the windows-rs crate (v0.61.3) and pxfm crate, reproducible under both rustc 1.94.1 and 1.96.1. Root cause is the project's aggressive release profile in src-tauri/Cargo.toml: opt-level='z' + codegen-units=1 + lto=true triggers an LLVM/rustc codegen crash on these large generated crates. Confirmed fix: overriding just opt-level=2, codegen-units=16 via CARGO_PROFILE_RELEASE_OPT_LEVEL/CARGO_PROFILE_RELEASE_CODEGEN_UNITS env vars lets the windows crate compile cleanly in isolation. Earlier 'toolchain corruption' and 'cargo clean' theories were red herrings -- the missing-std/core-prelude errors seen on other crates were a cascade effect of cargo continuing after the crashed crate's .rlib was never written.

+
+WhispAssist recording fix + diagnosis (2026-07-06, branch feature_chore_bug_003): User reported new recordings had 'no sound' while old ones played. DIAGNOSED: NOT the 32->16bit change. Proved via ignored hardware test loopback_16bit_wav_captures_played_audio (played Windows Alarm01.wav through default device, captured peak i16=11670) that 16-bit loopback capture records real audio fine. Root cause: the recorded WAV was loopback-only, so a mic-only moment (user talking, nothing playing through speakers) recorded as silence while their voice still reached the transcript. FIX (user chose native-quality): added audio::MicBridge (AtomicU32 rate + Mutex<VecDeque<f32>>, cap ~0.5s for clock-drift): loopback thread publishes its rate + pulls mic samples per-frame and mixes into every channel in write_wav_bytes(mic:&[f32]); mic thread resamples its audio to loopback rate (Resampler::new_to) and pushes to the bridge. New WasapiCapture::start_loopback_recording / start_microphone_recording; commands.rs uses them with a shared bridge when mic enabled. Recording is now native rate/stereo 16-bit WITH the user's voice. Verified by ignored test loopback_recording_with_mic_bridge_captures_played_audio (peak i16=22358). This SUPERSEDES the earlier 'mic transcript-only, not in WAV' limitation.

+
+CONFIRMED ROOT CAUSE (2026-07-02) of the WhispAssist whisper.cpp model-load crash: it is Trend Micro Security Agent (Worry-Free Business Security, corporate-managed -- services ntrtscan/TMBMServer/TmCCSF/tmlisten all running) injecting into whispassist.exe and hooking file I/O / MessageBox APIs. Live cdb attach to the process while the 'Debug Assertion Failed: _osfile(fh) & FOPEN' dialog was showing revealed 'tmmon64' (Trend Micro's monitoring module) sitting directly in the call stack between USER32!MessageBoxW and ucrtbased!__acrt_MessageBoxW, and the read path (whisper.cpp's std::ifstream -> xsgetn -> fread) resolves into ucrtbased.dll (debug CRT) even though whisper-rs-sys's CMakeCache.txt confirms /MD (release CRT) was used to build it -- i.e. Trend Micro's hook is corrupting the CRT call path, not a real build misconfiguration. Ruled out first: NOT a stack-size issue (tried 16MiB worker thread stack, crash identical), NOT stale/corrupted build artifacts (crash reproduces identically from a fully clean cargo clean --profile dev rebuild), NOT Windows Defender (already excluded target/ and C:\Users\dadous\AppData\Local\WhispAssist, crash persisted). Fix requires excluding whispassist.exe / the WhispAssist install and model directories from Trend Micro's real-time scan and behavior monitoring -- likely needs corporate IT/policy admin involvement since TMBMServer implies tamper-protected central management, not a self-service local exclusion like Defender. Tooling note: installed WinDbg Preview via 'winget install --id Microsoft.WinDbg' -- ships cdbX64.exe (classic command-line debugger) alongside the modern WinDbgX.exe GUI, usable for live process attach analysis without needing the full Visual Studio IDE debugger.

+### Fixed a real bug behind reported 30-65 second live...
+
+Fixed a real bug behind reported 30-65 second live-transcription lag: whisper.cpp's encoder always runs over a full padded 30-second mel window (1500 encoder positions) unless audio_ctx is explicitly reduced via set_audio_ctx. WhispAssist's live-transcription streaming windows are only about 4 seconds each but were never setting audio_ctx, so every window paid the full 30-second-equivalent encode cost, serially, on one worker thread. Fixed in src-tauri/src/transcription/mod.rs (function audio_ctx_for_window) by scaling audio_ctx proportionally to the real window length (1500 positions = 30s, so a 4s window gets about 201). Committed as 8530a22. Verified about 30 percent faster in a controlled A/B benchmark, though that specific test ran under heavy CPU contention from Docker Desktop and other concurrent Claude Code sessions on this machine, which likely masks a larger real-world improvement since the fix targets the encoder O(n^2)-ish attention cost specifically.

+
+WhispAssist dev/test workflow gotchas (2026-07-06): (1) A running 'npm run tauri dev' / whispassist.exe holds the cargo build lock on its target dir — STOP it (Stop-Process -Name whispassist, plus kill the node/cargo/vite procs whose CommandLine matches tauri|whispassist|vite) BEFORE running cargo build/clippy/test or the build blocks on the lock. (2) 'npm run tauri dev' writes output to the Windows console handle, NOT the redirected background-task log file (which stays empty) — confirm the app actually launched via Get-Process whispassist, not by reading the log; it typically appears ~30s after launch. (3) The audio-device tests find_render_device_none_matches_get_default_device and find_render_device_unknown_id_falls_back_exactly_like_none are FLAKY under cargo test (the wasapi get_default_device(Render) COM quirk) — a rerun passes; do NOT chase them as regressions.

+WhispAssist tooling FOOTGUN (2026-07-06): 'npm run format' = 'prettier --write .' — it reformats the ENTIRE repo, not just changed files. Running it during a small change reformatted 120+ files (all docs/ADRs/.claude skills/CLAUDE.md/stores/etc) because the repo isn't uniformly prettier-clean, burying the real diff. RECOVERY that worked: git diff --name-only | grep out the intended KEEP files | xargs git checkout -- , then verify only intended files remain; the reformats were content+EOL noise (git diff -w showed EOL-only for many). LESSON: to format/verify only your touched files use 'npx prettier --write <files>' or just 'npm run check' (svelte-check) + 'npx eslint <files>' which don't write. ALSO: 'npm run lint' currently reports ~143 PRE-EXISTING errors (mostly 'console'/'process' is not defined no-undef in node-context files) unrelated to app code — don't be alarmed, they predate any given change. Repo has mixed LF/CRLF (git warns 'LF will be replaced by CRLF'); harmless line-ending churn.

+WhispAssist dev-run finding (2026-07-06): 'npm run tauri dev' builds the Rust with features audio,cpu-transcription,diarization,pst,sync,npu = the DEFAULT set MINUS vulkan and cuda. Consequence: the everyday dev/default build has NEITHER a whisper.cpp GPU backend NOR CUDA, so on the Intel Core Ultra + Arc iGPU dev machine the ONLY GPU accel path is DirectML (via the ort/npu feature) — and directml_would_help() returns TRUE there, so the DirectML Settings card is visible. To exercise the Vulkan path you must build with --features vulkan explicitly (see whispassist-vulkan-build-recipe). Incremental dev rebuild ~42s once whisper.cpp/deps are cached; debug binary at src-tauri/target/debug/whispassist.exe. Launch recipe: load vcvars64.bat (VS2022 BuildTools) then 'npm run tauri dev'; the WebView2 window opens on the user's desktop. Opening Settings does NOT trigger the debug-CRT Abort/Retry/Ignore assertion dialog (that only fires on the transcription file-read path), so a UI-only visual check on the debug build is safe.

CRITICAL FINDING (user-confirmed): CPU was ALREADY ~90s BEFORE Vulkan was added — so the Vulkan build did NOT regress the CPU path; the 0.1.4 Vulkan build is SAFE to ship (CPU fallback unchanged). The ~90s CPU is a PRE-EXISTING bug in the full transcribe_file path, NOT caused by Vulkan. Vulkan and NPU are ~16-20x faster than the broken CPU path. Note the STREAMING path was already fixed earlier (audio_ctx scaling, commit 8530a22); transcribe_file (single_segment=false, 30s-padded seek loop) is the still-slow one.

Recordings are now native-quality (~50-100 MB) and the old put() buffered the whole file into memory in one PUT; OneDrive/Graph also caps a single PUT at 250 MB. Fixed by streaming disk-to-network in fixed-size chunks on both sync backends: WebDavTarget::put and OneDriveTarget::put now use tokio::fs::File + BufReader (O(chunk) memory, not O(file size)) for every upload. Files at/below LARGE_FILE_THRESHOLD (8 MiB) still take a single streamed PUT — only large artifacts (.wav recordings) take the chunked path. WebDAV (Nextcloud/ownCloud) implements the chunking-v2 protocol; OneDrive uses Graph's upload-session API.

+WhispAssist calendar/PST recurrence expansion (2026-07-06, commits fa8a7f2/6f07f28): expand_rrule in calendar/mod.rs now parses RRULE (DAILY/WEEKLY/MONTHLY/YEARLY, INTERVAL/COUNT/UNTIL/BYDAY/BYMONTHDAY/BYMONTH) and expands each recurring PST event into its own stored row keyed by '{uid}@{ymd}' for dedup, instead of only storing the first occurrence. Rewritten on chrono::Local (promoted from transitive to direct dependency) instead of hand-rolled epoch-day math, because the first version had a real DST bug: it kept a fixed UTC time-of-day per occurrence, so a meeting created in winter (CST) drifted an hour once its weekly recurrence crossed into summer (CDT) - e.g. 16:30 UTC showed correctly as 10:30 in January but wrongly as 11:30 in July. Fix: convert dtstart to local wall-clock once, keep hour/min/sec fixed, re-resolve the UTC offset per occurrence date. Tests assert local wall-clock time is identical across all occurrences (would fail under the old code).

New list_render_devices()/list_audio_devices command (wasapi crate already supported enumeration, just was unused until now). Settings.audio_output_device: Option<String>, #[serde(default)] for backward compat.

Built by an agent in an isolated git worktree, but that worktree's base snapshot was stale (pre-dated M1/M2 - based on 3038b9d, not the then-current feature_chore_bug_005 HEAD) - a real limitation of this session's worktree isolation mechanism worth remembering: it can silently reuse an earlier repo snapshot rather than the live current branch when a new worktree agent is launched later in the same session. Concretely this meant the M3 agent never saw M1's LlmProvider::complete() trait method addition, so AnthropicProvider::complete() was left as M1's not-yet-implemented stub even though M3 finished summarize/suggest_tags/status for real. Caught this by grepping the worktree for 'fn complete' before merging (found nothing) rather than trusting the agent's done report, then implemented AnthropicProvider::complete_with_key (non-streaming POST to /v1/messages, mirrors suggest_tags_with_key) myself as part of merge reconciliation. Also resolved three merge conflicts: llm/mod.rs (the complete() gap above), and two lucide-icon-import-list conflicts in Settings.svelte/SummaryPanel.svelte (M2 and M3 each added their own icon imports at the same insertion point) - unioned both, verified every icon is actually used before committing. What M3 built: AnthropicProvider real implementation (x-api-key + anthropic-version headers, SSE streaming for summarize, non-streaming for tags/complete), set_llm_provider storing the Anthropic key only in the OS credential store (never settings.json/DB, tested) and adding api.anthropic.com to the egress allowlist only when actually configured, HostedAiBanner.svelte one-time third-party-egress acknowledgment component, active-provider indicator + per-use quick-switch in SummaryPanel. Verified independently end to end on the fully merged M1+M2+M3 tree: cargo test --features mcp = 165 passed/0 failed, clippy clean (default + --features mcp), cargo fmt clean (only the same pre-existing unrelated audio/mod.rs drift as before), svelte-check 0 errors. Lesson for future milestone builds in this repo: after any worktree-isolated agent finishes, grep for the specific trait methods/functions the previous milestone added before trusting 'this builds on M<n-1>' claims - isolation snapshots can silently drift stale mid-session.

+WhispAssist meeting title + tags features (2026-07-06, commits 2efe295/e68e888 and 68c32ff/16fcb15): (1) meetings previously had NO way to rename from 'Untitled meeting' anywhere in the UI - added an inline-editable title header above the transcript/notes pane (TranscriptNotes.svelte) backed by a new rename_meeting command; (2) attach_meeting_to_event now also mirrors the linked calendar event's subject onto the meeting's title when it has one, so linking 'Jerry / Daniel - Weekly 1:1' auto-renames the meeting; (3) added a 'Generate tags' feature mirroring 'Generate summary' - new LlmProvider::suggest_tags trait method (implemented for Ollama/OpenAI-compatible/Anthropic-stub), reads the transcript via the same build_prompt assembly, non-streamed, returns 1-8 tags merged into (not replacing) the existing tag list; (4) replaced the old comma-separated text-input tags UI with GitHub-topics-style removable/clickable chips (new shared TagChip.svelte component using existing --accent/--accent-soft tokens) - clicking a chip's label calls meetings.filterByTag() which filters the sidebar meeting list, an 'x' removes it.

Removed assetProtocol config + tauri protocol-asset feature + convertFileSrc; CSP media-src now 'self' http://waaudio.localhost.

The NPU (OpenVINO) and DirectML runtimes are now downloaded as .7z (LZMA2+BCJ) from gitea RAW paths: NPU=https://git.dou.bet/iamdoubz/WhispAssist/raw/branch/main/runtime/openvino.7z (SHA ca0be9fc52c78ee623b152f790450b3d4020c5a7ebe99d27736455b308782191), DirectML=https://git.dou.bet/iamdoubz/WhispAssist/raw/branch/main/runtime/directml.7z (SHA 34369222fcc1be2e72a957b868b1976a90150ba704a06c9e8992c34ee368926b). REPLACED the zip crate with sevenz-rust2 (pinned 0.7.0 — newer needs rustc>1.77 MSRV; optional + npu-gated). extract_zip_flat -> extract_7z_flat (uses decompress_file_with_extract_fn, flattens basenames — archives nest DLLs under directml/ and openvino/ folders). stage_directml_runtime now defaults to DIRECTML_RUNTIME_URL const (no longer requires WA_DIRECTML_RUNTIME_URL env). Env overrides WA_NPU_RUNTIME_URL / WA_DIRECTML_RUNTIME_URL still honored. sevenz-rust2 0.7.0 confirmed to decode LZMA2+BCJ (has src/bcj/x86.rs); validated by test extract_7z_flat_unpacks_the_directml_bundle (extracts ../runtime/directml.7z, asserts onnxruntime.dll == 17253408 bytes, flattened) — PASSES. clippy -D warnings clean on default/shipped build; 104+ tests green. NOTE: raw URLs point to branch/main, so they only resolve once runtime/openvino.7z + runtime/directml.7z are committed to MAIN. As of now those .7z files are UNTRACKED (left for the user to commit — plain git add vs Git LFS decision; ~27MB total). The old .zip package-registry URL (git.dou.bet/api/packages/.../npu-runtime/...) is retired. archives were created with 7z LZMA2:24m BCJ.

+### WhispAssist M1 (feature briefs) + M2 (MCP server) ...
+
+WhispAssist M1 (feature briefs) + M2 (MCP server) SHIPPED (2026-07-07, branch feature_chore_bug_005, merge commit 2582d89). Built in parallel by two agents in isolated git worktrees, then merged sequentially (M1 first, ff-merge; M2 second, conflict-merged). M1: Store methods for feature_briefs (insert/list/get_row/set_exposed), LlmProvider::complete() primitive (Ollama+OpenAI-compat), FeatureBriefBuilder distiller (briefs/mod.rs, keyword-overlap grounding), the 4 create/list/get_feature_brief+set_brief_exposed commands, SummaryPanel.svelte UI, golden-transcript tests. M2: mcp module on rmcp (loopback bind + token gate, Streamable HTTP + stdio adapter), 4 tools (list_recent_meetings/get_transcript/get_action_items/get_feature_brief), scope control (none|selected|all), mcp_status/set_mcp_enabled lifecycle (token in OS credential store), disclosure UI + mcp_access_log audit, privacy panel integration. Gated behind an optional mcp Cargo feature. Merge required resolving one real conflict (storage/mod.rs trait+impl interleaving) plus one real cross-branch integration bug: M2's handler.rs called commands::get_feature_brief(id) with the pre-M1 stub arity; fixed by extracting get_feature_brief_core(store, id) shared between the Tauri command and the MCP handler, and wired the previously-stubbed selected-scope exposed-flag check (scope::brief_visible) that M2 had left as a documented KNOWN GAP. Verified independently (not just trusting agent reports): cargo test --features mcp = 154 passed/0 failed, clippy clean (default + --features mcp), cargo fmt clean (only pre-existing unrelated audio/mod.rs drift), svelte-check 0 errors. Known environment gotcha hit repeatedly during verification: whisper-rs-sys native build intermittently fails with MSVC error C1056 'cannot update time date stamp' - Trend Micro AV interference, same class as the previously-recorded model-loading hang; resolved by retrying the build, not a code defect. Also: building in a deeply-nested git worktree path (.claude/worktrees/agent-id/...) can overflow Windows MAX_PATH during whisper.cpp's CMake TryCompile scratch dirs - work around with a short CARGO_TARGET_DIR (e.g. C:/wa-build-x) when testing worktrees directly. M2's one incomplete acceptance item: no compiled end-to-end MCP wire-protocol client test (blocked on an rmcp reqwest-0.13-vs-0.12 version conflict pulling in aws-lc-rs; agent reverted the attempt cleanly rather than leave it unverified) - unit-level loopback-bind-refusal and scope-enforcement tests substitute for now. Next: M3 (hosted AI providers, Anthropic) per user pre-authorization to skip the usage checkpoint and go straight to a scheduled resume.

+
+M4.3 (Dropbox/Box upload targets, T9.10, FR-SYNC-9) SHIPPED 2026-07-07 on branch feature_chore_bug_005 (commit 6991c1d), same day as M4.1/M4.2/M4.4 but a separate prior session. Implements DropboxTarget and BoxTarget SyncTarget impls (OAuth PKCE was already wired for both providers). DropboxTarget: path-addressed like OneDrive/WebDAV; create_folder_v2 creates the whole intermediate path in one call; upload-session chunking above LARGE_FILE_THRESHOLD (start/append_v2/finish). BoxTarget: Box addresses items by numeric ID not path, so ensure_dir/exists/put all walk (and lazily create) the folder chain from root ('0') by listing each level's children; always uploads via Box's session API regardless of file size (its session API takes plain PUT bodies, consistent with every other target, needs no new reqwest feature, and Box computes/returns each part's digest so no local hashing needed). Both follow the same documented ceiling as OneDriveTarget's put_chunked (M4.1): the upload-session id lives only for one put() call, not persisted across process restarts — a crash mid-chunked-upload restarts that file's upload from scratch rather than resuming (unlike WebDAV's chunking-v2 which is genuinely resumable).

+
+WhispAssist merged single installer (2026-07-06, branch feature_chore_bug_003): Combined the two installers (13MB default/NPU-DirectML at src-tauri/target vs 67MB Vulkan at C:\wt) into ONE universal Vulkan installer. Verified facts: default exe 13MB imports no vulkan-1.dll (runs anywhere, GPU via runtime DirectML); Vulkan exe 67MB imports vulkan-1.dll at LOAD time (dumpbin) so it won't launch without the loader. Fix (option A = bundle the loader): build.rs stage_vulkan_loader() runs when CARGO_FEATURE_VULKAN set — copies vulkan-1.dll from %VULKAN_SDK%\Bin (fallback C:\Windows\System32) next to the exe (OUT_DIR ancestors nth(3) = target/<profile>, correct under CARGO_TARGET_DIR=C:\wt) AND into src-tauri/ (gitignored) for bundling. New src-tauri/tauri.vulkan.conf.json overlay adds bundle.resources ['vulkan-1.dll']. Release build cmd: npm run tauri build -- --features vulkan --config src-tauri/tauri.vulkan.conf.json (needs VULKAN_SDK, CMAKE_GENERATOR=Ninja, CARGO_TARGET_DIR=C:\wt). VERIFIED end-to-end: built MSI+NSIS 0.1.6; WiX main.wxs shows vulkan-1.dll as a Component in the same install dir as whispassist.exe + sibling DLLs (onnxruntime/sherpa/whispassist_lib), so the loader finds it. DirectML stays hidden when vulkan compiled (directml_would_help returns false). STILL TO TEST BY USER: launch the merged installer on a clean VM with NO vulkan-1.dll / no GPU driver to confirm graceful CPU fallback before retiring the 13MB build.

(3) Smaller wav FR-CAP-8: wav_spec_for now forces 16-bit Int at native rate; write_wav_bytes quantizes f32->i16 via f32_to_i16 (clamp*i16::MAX) — halves 205MB->~103MB. Kept native rate (48k), did NOT resample to 44.1k (marginal, needs multichannel resampler in hot path). (4) Cancel recording FR-CAP-9: cancel_recording command stops loopback+mic, joins worker, store.delete_meeting (row+folder), emits recording://state state:cancelled; App.svelte Cancel button with confirm. (5) Live sync progress FR-SYNC-11: sync put() streams body via futures_util::stream::unfold + reqwest wrap_stream + Content-Length, sends incremental (sent,total); upload_job drains on a std thread (throttled 250ms) calling on_progress; pump_sync emits live sync://job; SummaryPanel <progress> bar.

(1) Settings panel horizontal-scroll/close-button-cutoff FIXED: the tab <nav> in Settings.svelte didn't wrap inside the fixed-width panel (width:min(720px,92vw)), overflowing and pushing the .close (X) button off-edge + adding a horizontal scrollbar. Fix: nav { flex:1 1 auto; min-width:0; flex-wrap:wrap }, header align-items:flex-start, .close flex:0 0 auto. (2) New ABOUT page (Settings ▸ About, Info icon tab): shows version (env!(CARGO_PKG_VERSION)) + build commit hash + a source link to https://git.dou.bet/iamdoubz/WhispAssist. Commit hash baked at build time via build.rs (git rev-parse --short HEAD -> cargo:rustc-env=WA_GIT_HASH, rerun-if-changed=../.git/logs/HEAD). Two new Tauri commands: app_info()->{version,commit}, open_url(url) (validates http(s), Windows-only via 'explorer <url>' — no shell injection, reuses installed toolchain instead of adding tauri-plugin-opener). api.ts got AppInfo type + appInfo()/openUrl() bindings. NOTE the section {#if}/{:else if} chain in Settings.svelte: privacy was the catch-all {:else} — adding an About branch required converting privacy to {:else if section==="privacy"} because {:else if} can't follow {:else}. Version bumped 0.1.4->0.1.5 in package.json, src-tauri/Cargo.toml, src-tauri/tauri.conf.json, Cargo.lock (package-lock.json tracks app version as 0.0.0, untouched). clippy -D warnings + svelte-check + eslint(my files) all clean.

+
+WhispAssist sync-target EDIT feature added (2026-07-06, commits 149f2c9/45b2acb/496a337/fb79009). Root cause of the user's Nextcloud auth failure: the saved target's base_url was missing the /remote.php/dav/files/<user>/ path (they entered just the host) -> PROPFIND hit a non-DAV path -> 401. Credentials + app password were CORRECT (verified via curl PROPFIND returning 207 + X-User-Id). The app had NO way to edit a saved target — only add/delete/toggle-enabled — so they couldn't fix the URL. FIX: the backend update_sync_target command + store + api.updateSyncTarget ALREADY existed (was only used by the enable toggle); added the missing UI. Changes: (1) SyncTargetInfo (models.rs + api.ts) gained upload_transcript/notes/summary/recording, trigger_on_finalize, allow_plaintext_lan, encrypt_before_upload + row_to_info populates them (secret still never exposed, FR-SYNC-6); (2) settings.svelte.ts store.updateTarget(); (3) Settings.svelte: per-webdav-target Edit button -> startEdit() loads it into the add-form (secret blank), heading/submit become 'Edit target'/'Save changes', kind tabs hidden during edit, Cancel button. Password left blank on save = keep stored (update only rotates the credential when a non-empty secret is provided). Test-connection in edit mode tests the TYPED values (form has no id) so it needs the password re-entered; the simpler fix-and-save path preserves the secret. Correct Nextcloud WebDAV base_url = https://HOST/remote.php/dav/files/USERNAME/ . clippy + svelte-check + eslint all clean.

+WhispAssist DirectML Settings toggle WIRED (2026-07-06, branch chore_debug, 4 commits 281ccf0/ceb7e59/1b743da/1b74e0b). Backend: hardware::directml_would_help() (pub, in hardware/mod.rs) = cfg!(feature=npu) && !cfg!(feature=vulkan) && a present AMD/Intel GPU (or NVIDIA when !cfg!(cuda)) via dxgi::enumerate_gpus() presence — gates the card so it stays HIDDEN on the shipping Vulkan build (Vulkan already covers all GPUs) and only shows on CUDA/non-Vulkan builds where a GPU lacks coverage. hardware_status now returns directml:{applicable,runtimeReady,modelInstalled} (mirrors the npu:{} field). Frontend: api.ts HardwareStatus gained directml?:{applicable,runtimeReady,modelInstalled} + api.downloadDirectmlPackage(); Settings.svelte has a 'GPU acceleration (DirectML)' card mirroring the NPU package card (reuses .npu-package CSS), shown when directml.applicable, Ready badge when runtimeReady&&modelInstalled else a Download button -> downloadDirectmlPackage() -> loadHardware(). Progress is await-driven (busy flag), NO % listener — DirectML runtime/model progress still emits on the cosmetic npu://download channel (only 'done' on directml://download). It's a package-DOWNLOAD action, not a persistent on/off toggle; the real 'use this GPU' switch is the existing Preferred-backend dropdown (which now enables AMD/Intel once staged, via the P0 availability fix). clippy -D warnings + svelte-check both clean (fixed a needless_return in directml_would_help by using the cfg-block tail-expression pattern like npu_hardware_present).

+
+WhispAssist Nextcloud sync UX overhaul (2026-07-06, commits 8f6e804/9c670f9). ROOT CAUSE of user's confusion (dwdoubet@box.dou.bet): they were editing with the password field BLANK. WebDavTarget.test() does PROPFIND on base_url+remote_base_path. Bare host https://box.dou.bet + blank pw -> PROPFIND https://box.dou.bet/WhispAssist = NON-DAV path -> 404 (no auth needed) -> test treats 404 as success -> FALSE 'Connected'. Full DAV URL + blank pw -> real DAV endpoint -> 401 -> 'auth failed'. So bare-host 'Connected' was a false positive. FIX 1: WebDavTarget gained provider_hint field; for nextcloud/owncloud, dav_root() derives origin (scheme+host+port) from base_url and builds {origin}/remote.php/dav/files/{username}/ — so users enter ONLY the server URL (https://box.dou.bet) and the app builds the canonical DAV path; a pasted full path is normalized via origin(). Other providers (seafile /seafdav, synology /dav, cloudreve, generic) still use base_url verbatim. url_for uses dav_root(). FIX 2: test_sync_target — for an EXISTING webdav target (id present), it now builds WebDavTarget from the stored row's credential_ref (STORED password) + applies form overrides (base_url/username/remote_base_path/provider_hint/allow_plaintext_lan), unless the user typed a NEW password (temp cred). So Test works after a URL fix WITHOUT re-entering the password. Frontend: davAutoPath derived (provider is nextcloud/owncloud) drives the Server URL placeholder/hint; testConnection passes id in edit mode. Test nextcloud_builds_dav_path_from_server_url added. Correct Nextcloud username here = dwdoubet, host box.dou.bet. NOTE: their existing saved target may just start working after this (url_for rebuilds path from origin+username) if provider_hint=nextcloud. clippy --all-targets + svelte-check + eslint clean; 13 sync tests pass.

+WhispAssist crash to INVESTIGATE LATER (2026-07-06, dev build, branch feature_chore_bug_002): app crashed with exit code 0x80000003 (STATUS_BREAKPOINT) around DirectML use on an Intel GPU. Repro sequence: NPU recording worked fine (mic capture confirmed working); user then switched to test DirectML, downloaded the DirectML components, then hit Record and it crashed — crash may have occurred DURING the component download or immediately after starting recording. Log evidence at crash: WARN 'ONNX engine load failed (model load failed: Error attempting to load symbol OrtSessionOptionsAppendExecutionProvider_DML from dynamic library: GetProcAddress failed); falling back to CPU', then whisper_model_load loading ggml-small.en-q5_1.bin, then process exited 0x80000003. CONFIRMED unrelated to the microphone/mixer feature (FR-CAP-7) — it's in the DirectML/ONNX + whisper model-load path. Suspect: DirectML runtime download/activation or DML EP symbol-load failure interacting with recording start. Next: reproduce by enabling DirectML on Intel GPU + start recording; check GetProcAddress DML symbol load and whether crash is during download vs whisper load.

+WhispAssist build gotcha (cost ~1hr this session, masqueraded as a Node 26 incompatibility): NEVER use PowerShell 'Set-Content -Encoding utf8' on package.json / tauri.conf.json / any JSON or TOML — Windows PowerShell 5.1 writes UTF-8 WITH a BOM. The BOM in package.json breaks vite (fails 'type:module' detection -> 'This package is ESM only but was loaded by require' for @sveltejs/vite-plugin-svelte) AND vitefu (JSON.parse chokes: 'Unexpected token, not valid JSON' -> 'Unable to read package.json'), which fails 'npm run build' / the whole tauri build. Fix: use the Edit tool, or sed, or [System.IO.File]::WriteAllText. Strip an existing BOM with: sed -i '1s/^\xef\xbb\xbf//' file. Node was v26.3.0 at C:\Tools\node but Node was NOT the cause.

+
+Critical recurring issue: WhispAssist debug (dev) builds hang/stall during whisper.cpp model loading on this machine, apparently due to Trend Micro AV behavior-monitoring interfering with ZwWriteVirtualMemory calls made during model load. Confirmed reproducible even in a bare standalone Rust example binary with zero Tauri/webview involvement, so it is specific to whisper.cpp model loading in a debug-profile binary, not the app shell. Release (optimized+stripped) builds do NOT hit this - confirmed by the user and by direct testing. Escalated to IT, unresolved as of 2026-07-02. Workaround: use release builds for real testing/spot-checking; expect dev-mode launches to sometimes hang at model load and need force-killing.

+
+WhispAssist CRITICAL BUG FOUND + FIXED (2026-07-06): the OS credential store was a NO-OP the entire time. keyring 3.x feature-gates its platform backends and they are OFF by default; 'keyring = { version = "3", optional = true }' had NO backend feature, so on Windows keyring silently used its MOCK keystore. The mock does NOT persist across keyring::Entry instances, so credentials::set (Entry A) appeared to succeed while credentials::get (a fresh Entry B, same service+name) always returned NoEntry -> has_secret=false -> no HTTP Basic auth sent -> 401. This broke ALL sync WebDAV auth, and would break MCP/hosted-AI keys + OAuth tokens too (anything via sync::credentials, SERVICE='WhispAssist-sync'). FIX: keyring = { version = "3", optional = true, features = ["windows-native"] } (pulls dep:windows-sys = real Windows Credential Manager). Confirmed: WA_SYNC_TEST_DIAG went from status=401 has_secret=false to status=207 has_secret=true. DIAGNOSIS JOURNEY (Nextcloud box.dou.bet user dwdoubet): symptom 'auth failed'; the user's credentials + full DAV URL were valid (curl PROPFIND 207). Red herrings: (a) earlier the Nextcloud base_url was missing /remote.php/dav/files/<user>/; (b) a bare-host test gave a FALSE 'Connected' because a non-DAV path 404 is treated as success; (c) blank password in edit test. Real root cause was keyring. TOOLING NOTE: diagnosed via temporary tracing::info! logs (WA_SYNC_CMD_DIAG in test_sync_target = has_id+secret_len; WA_SYNC_SET_DIAG in add branch; WA_SYNC_TEST_DIAG in WebDavTarget::test() = url+status+has_secret) read live from the 'npm run tauri dev' output (tracing filter is 'info' in lib.rs). Also learned keyring feature name = windows-native, and the app's tracing default level is info. These temp diagnostics MUST be removed before release.

+WhispAssist debug-CRT assertion (found 2026-07 while running the non-vulkan CPU baseline in DEBUG): the whispassist_lib debug test binary throws MSVC Debug Assertion 'Expression: _osfile(fh) & FOPEN' at ucrt read.cpp:381 = a read() on a CLOSED/invalid file handle. It pops a MODAL Abort/Retry/Ignore dialog that HANGS the test (this is what stalled the overnight non-vulkan baseline run for 8 hours). Only fires under the debug CRT (-MDd); the RELEASE 0.1.4 build does NOT assert (release CRT skips the check), so shipping is unaffected — but the underlying 'read on a closed handle' is latent UB worth root-causing. Likely in the transcription file-read path (whisper.cpp model load or our audio read_wav_mono_16k / vault::open passthrough). ADD to the CPU testing round: investigate this handle bug alongside the ~90s transcribe_file slowness (may or may not be related). Workaround to get a clean non-vulkan CPU number: run 'cargo test --release' (no debug CRT dialog), not plain 'cargo test'.

+## Remaining work — post-v0.2.0 execution plan
+
+As of **v0.2.0**, Phases 1–9 ship (capture incl. microphone, CPU/NPU/Vulkan transcription,
+diarization, storage/recovery, notes, local-LLM summaries, PST calendar, UX/a11y,
+templates/search/tags/export/reminders/encryption, WebDAV + OneDrive sync) in a single universal
+installer. What remains is **Phase 10 (external AI & agent handoff, ADR-0011)** plus a few
+breadth/reliability items. This section sequences that work by leverage, dependency, and the
+privacy invariant. Task IDs reference the Phase 10 list above; finer sub-tasks add a letter suffix.
+Traits/contracts for all of this already exist in `04-api-contracts.md` (`FeatureBriefBuilder`,
+`McpServer`, hosted `LlmProvider` impls, `AgentRunner`, `IssueTracker`); tests live in
+`06-test-strategy.md` (P10 + the cross-cutting egress gate).
+
+**Status snapshot (what's actually in the tree):**
+- **Built:** Phases 1–9; `OpenAiCompatProvider` (used as the Phase 5 "custom" endpoint); chunked/
+  resumable upload (M4.1); multi-language transcription (M4.2); `DropboxTarget`/`BoxTarget` (M4.3);
+  MS Graph `CalendarSource` (`GraphSource`, M4.4).
+- **Stubbed** (commands return `Err(not_implemented(...))`): `create/list/get_feature_brief`,
+  `set_brief_exposed`, `mcp_status`, `set_mcp_enabled`, `set_mcp_scope`, `mcp_access_log`,
+  `run_agent`, `create_issue_from_brief`.
+- **Skeleton/absent:** `mcp/mod.rs` (trait + `todo!()` only); `AnthropicProvider` (returns
+  "isn't built yet").
+
+**Sequence:** M1 → M2 (briefs are the MCP payload); **M3 can run in parallel** with M1/M2; M4 is
+opportunistic; **M5 is last and optional**.
+
+### M1 — Feature briefs (do first; standalone value) → FR-MCP-4 (T10.6)
+Needs only the already-built LLM, delivers value before any MCP transport (view/copy a brief), and
+is the exact payload M2 serves. **No new egress** (uses the configured `LlmProvider`).
+
+**Already scaffolded — do NOT re-create:** IPC types `FeatureBrief`/`FeatureBriefInfo`/
+`ContextExcerpt` (`models.rs`); `api.ts` bindings `createFeatureBrief`/`listFeatureBriefs`/
+`getFeatureBrief`/`setBriefExposed`; the four commands registered in `lib.rs`; DB tables
+`feature_briefs` + `mcp_access_log` (`migrations/0003_ai_mcp.sql`); the `briefs/<id>.json` schema
+(`03-data-model.md`) and the `FeatureBriefBuilder` trait (`04-api-contracts.md`). The four command
+bodies today return `Err(not_implemented(...))` — M1 fills them in.
+
+- `[M1.1]` **Storage methods** (`Store` trait + `SqliteStore`, `storage/mod.rs`) over
+  `feature_briefs`; row struct `FeatureBriefRow { id, meeting_id, title, target_repo: Option<String>,
+  path, exposed: bool, created_at }`. Deletion cascades via the meeting FK (existing `delete_meeting`
+  already drops the row + folder). **S**
+  - `async fn insert_feature_brief(&self, row: FeatureBriefRow) -> Result<(), StoreError>;`
+  - `async fn list_feature_briefs(&self, meeting_id: Option<&MeetingId>) -> Result<Vec<FeatureBriefInfo>, StoreError>;` (newest first)
+  - `async fn get_feature_brief_row(&self, id: &str) -> Result<FeatureBriefRow, StoreError>;` (resolves `path`)
+  - `async fn set_brief_exposed(&self, id: &str, exposed: bool) -> Result<(), StoreError>;`
+- `[M1.2]` **LLM completion primitive** (`llm/mod.rs`) — one non-streaming method on `LlmProvider`
+  (mirrors `suggest_tags`), implemented for `OllamaProvider` + `OpenAiCompatProvider` now (Anthropic
+  lands in M3): `async fn complete(&self, system: &str, user: &str) -> Result<String, LlmError>;`. **S**
+- `[M1.3]` **`FeatureBriefBuilder`** (new `briefs` module) — the distiller. **M**
+  - *Prompt contract* (system, reuse the `RESPONSE_FORMAT_INSTRUCTIONS` pattern): "Distill this
+    transcript into an implementation brief for a coding agent. Respond in Markdown with exactly, in
+    order: `## Title` (one line), `## Problem`, `## Desired Outcome`, `## Acceptance Criteria` (a
+    `- ` bullet list, one testable criterion per line). Be concrete and terse; invent nothing not in
+    the transcript; no other sections." *User*: `build_prompt`-style metadata + optional `target_repo`
+    hint + `"Transcript:\n" + transcript`.
+  - *Parser* `parse_brief(md) -> BriefFields { title, problem, desired_outcome, acceptance_criteria }`
+    — mirror `parse_summary`/`bullet_text`; missing section → `""`/`[]`; title fallback = meeting title.
+  - *`context_excerpts` (grounding, verbatim)*: tokenize `problem + acceptance_criteria`, score each
+    transcript segment by keyword overlap, take the top ≤5 of length ≥ ~40 chars (fallback: first 3
+    substantive segments); `speaker` = resolved display name. `// ponytail: keyword-overlap select;
+    upgrade to embedding similarity if excerpts feel off`.
+- `[M1.4]` **Command bodies** (`commands.rs`, replace the four stubs; keep names/args so `api.ts` is
+  unchanged — add `state: State<'_, AppState>`, which Tauri injects). **M**
+  - `create_feature_brief(state, meeting_id: MeetingId, target_repo: Option<String>) -> WaResult<FeatureBrief>`
+    — reject the currently-recording meeting; `load_settings()` + `llm_provider_from_settings()`
+    (error if none); load transcript via `state.store`; run the builder; assemble `BriefFile { schema:
+    1, id, meeting_id, generated_at, provider, model, …fields, source }`; `vault::seal` → write
+    `briefs/<id>.json` under `meeting_dir`; `store.insert_feature_brief(row)` (`exposed=false`);
+    return the IPC `FeatureBrief`. **Write the file + row only after a successful distill** (no partial
+    artifacts on LLM failure).
+  - `list_feature_briefs(state, meeting_id: Option<MeetingId>) -> WaResult<Vec<FeatureBriefInfo>>`
+  - `get_feature_brief(state, id: String) -> WaResult<FeatureBrief>` (row → `vault::open(path)` → subset)
+  - `set_brief_exposed(state, id: String, exposed: bool) -> WaResult<()>`
+- `[M1.5]` **UI** (`SummaryPanel.svelte` or a new "Feature briefs" block; existing bindings, no new
+  client code): "Create feature brief" button + optional target-repo input; list via
+  `listFeatureBriefs(meetingId)`; viewer with **copy-as-Markdown** and **copy-as-JSON**; `exposed`
+  toggle wired to `setBriefExposed` but shown as "available when the MCP server is on" until M2. **M**
+- `[M1.6]` **Tests — golden transcript** (see `06-test-strategy.md` P10): `parse_brief` unit
+  (golden reply → fields; empty/malformed → empty, no panic); builder over a golden transcript with a
+  `MockLlmProvider` (no network) asserting the fields, non-empty `acceptance_criteria`, and the
+  **grounding invariant** (every excerpt text is a verbatim substring of a transcript segment);
+  command-level: LLM off/unreachable → `Err`, nothing written. **S**
+
+- **Acceptance (M1 done):** on a finished meeting with an LLM configured, "Create feature brief"
+  produces a schema-valid, vault-sealed `briefs/<id>.json` + a `feature_briefs` row that lists and
+  re-opens; excerpts are verbatim from the transcript; with the LLM off/unreachable the command errors
+  cleanly and writes nothing partial; the golden-transcript unit tests pass. No new egress; `exposed`
+  defaults off.
+
+### M2 — MCP server (the differentiator) → FR-MCP-1/2/3/5/6/7 (T10.4/10.5/10.7/10.8/10.9)
+The unique capability (meeting → coding-agent handoff) and a privacy *reinforcement*: inbound on
+loopback, **zero added egress**.
+- `[M2.1]` `mcp` module on `rmcp`: loopback bind + token gate; Streamable HTTP (`/mcp`) + stdio
+  adapter; implement `McpServer::start/stop` (replace `todo!()`). **L** → FR-MCP-1/6, NFR-SEC-5
+- `[M2.2]` Tools-first surface: `list_recent_meetings`, `get_transcript`, `get_action_items`,
+  `get_feature_brief`. **M** → FR-MCP-2
+- `[M2.3]` Scope control `set_mcp_scope(none|selected|all)`; recordings never served unless
+  explicitly allowed; enforce in every tool handler. **M** → FR-MCP-3
+- `[M2.4]` Lifecycle: `mcp_status`/`set_mcp_enabled` (replace stubs); persist enabled/scope in
+  settings, **token in the OS credential store** (never `settings.json`). **M** → FR-MCP-1
+- `[M2.5]` Disclosure UI ("connected agents may forward data") + `mcp_access_log` rows /
+  `mcp://access` events on every tool read. **M** → FR-MCP-5
+- `[M2.6]` Privacy panel shows MCP state and confirms it adds no egress; extend
+  `privacy_self_check`. **S** → FR-MCP-7, FR-SEC-2
+- **Acceptance:** an in-process MCP client gets a schema-valid brief; server binds loopback only
+  (assert a non-loopback bind is refused) and requires a token; **the egress test is unchanged with
+  MCP on** (merge blocker, FR-MCP-7); recordings not served unless allowed; every read logged.
+- **Depends on:** M1 (a served tool). Guardrail: the cross-cutting egress gate must stay green.
+
+### M3 — Hosted AI providers (finish 10a) → FR-AI-1/2/3 (T10.1/10.2/10.3)
+Commodity but low-effort (OpenAI-compat already exists); gives a cloud-summary choice and pairs with
+M1 (a brief can be distilled by a hosted model). Adds allowlisted egress **by design**.
+- `[M3.1]` Implement `AnthropicProvider` (`/v1/messages`, `x-api-key`, streaming) behind
+  `LlmProvider`; `is_local() == false`. **M** → FR-AI-1
+- `[M3.2]` `set_llm_provider`: store the API key in the OS credential store via `credential_ref`
+  (never settings/DB); add the host to the settings-derived egress allowlist. **M** → FR-AI-2, NFR-SEC-4
+- `[M3.3]` Third-party "data leaves your device" banner + one-time acknowledgment; per-use provider
+  selection + active-provider display wherever a summary is generated. **S** → FR-AI-2/3
+- **Acceptance:** summaries route to mocked OpenAI-compat *and* Anthropic endpoints with correct
+  shapes; key read only from the credential store; host on the allowlist only when configured; banner
+  shown before first hosted use.
+
+### M4 — Reliability & breadth (opportunistic, by value)
+- `[M4.1]` **Chunked/resumable upload** (T9.2 refinement) — *top reliability item*: recordings are
+  now native-quality (~50–100 MB) and `put()` buffers the whole file in memory; OneDrive/Graph caps a
+  single PUT at 250 MB. Stream from disk in chunks (Nextcloud chunked upload + Graph upload session).
+  **M** → FR-SYNC-2/5
+- `[M4.2]` Multi-language transcription (T8.7): multilingual model option; whisper language param
+  (select/auto); persist per-meeting `language`; UI localization scaffold. **M** → FR-TRX-4
+- `[M4.3]` Dropbox/Box upload targets (T9.10): implement `DropboxTarget`/`BoxTarget` `SyncTarget`
+  impls (OAuth is already wired). **M** → FR-SYNC-9
+- `[M4.4]` MS Graph calendar source (T8.9) behind `CalendarSource` (`GraphSource`), consented
+  (OAuth PKCE), metadata-only. **L** → FR-CAL-6 (Could) — **shipped**.
+
+### M5 — Push handoff (Layer 3, last & optional) → FR-AGENT-1/2 (Could) (T10.10/10.11)
+Only on demand — the MCP handoff (M2) already covers the agent use case (agents *pull* context).
+- `[M5.1]` `AgentRunner`: spawn `claude -p` / `codex exec` / `opencode run` / `copilot` headless
+  against a chosen repo from a brief; stream output (`run_agent`). **L** → FR-AGENT-1
+- `[M5.2]` `IssueTracker`: create a GitHub issue from a confirmed action item / brief; optional
+  Copilot-cloud assign (`create_issue_from_brief`). Third-party egress: off/labeled/allowlisted. **M**
+  → FR-AGENT-2
+
+**Privacy checkpoints (gate every milestone):** the egress self-test stays green (FR-SEC-1); enabling
+MCP adds **no** allowlist host (FR-MCP-7); hosted AI/agent handoff adds only the explicitly configured
+host; all secrets (AI keys, MCP token, OAuth tokens) live only in the OS credential store
+(NFR-SEC-4). Plus the standing gates: `cargo fmt`/`clippy -D warnings`, Prettier/ESLint/`tsc`, and a
