VersionHistory snapshots the previous content on every explicit save — an
unsaved buffer is still lost on crash. AutosaveBuffer fills that gap.
- src/main/AutosaveBuffer.js — pure module mirroring VersionHistory's
injectable-IO pattern; one blob per doc path under
<userData>/autosave/by-path/<sha1>/recovery.md + meta.json. No history
(VersionHistory owns that) — just the latest dirty buffer.
- src/main.js — IPC channels autosave:write/read/clear/list; real paths
go through validatePath, synthetic 'untitled-tab-<id>' keys skip it.
- src/preload.js — added the four channels to ALLOWED_SEND_CHANNELS.
- src/renderer/autosave-client.js — debounced (2s) flush per tab +
periodic safety net (10s max age) + dirty-write retry on failure.
- src/renderer.js — register on tab create, unregister on close,
notifyChange piggybacks on performAutoSave's existing dirty-check,
clearForDocPath after a successful save, showAutosaveRecoveryBanner
on startup listing pending recoveries with Restore/Dismiss.
Tests (39 new):
- tests/main/AutosaveBuffer.test.js (19): round-trip, overwrite, isolation,
unicode/emoji, empty content, null coercion, ENOENT vs corrupt meta,
list ordering, corrupt-sibling skip, input validation, sha1 storage.
- tests/autosave-client.test.js (11): debounce, flushNow bypass,
no-path skip, clearForDocPath, list proxy, IPC error fallback,
unregister tear-down, failure-retry, periodic flush, idempotency.
Full suite: 692 tests pass, 63 suites, lint+format clean.

Bundle (v4.7.0):
- MarkItDown frozen to a single ~75MB per-platform binary (PyInstaller via
npm run bundle:markitdown; ML extras excluded) — built and verified
locally: HTML/XLSX/PDF conversions pass through the bundled binary, and
the app resolves bin/linux/markitdown first at runtime
- Packaging copies bundled markitdown alongside Pandoc for win/mac/linux;
FFmpeg/sharp/KaTeX/fonts were already bundled
Legal artifacts:
- THIRD-PARTY-NOTICES.md: complete license inventory of everything
distributed (binaries, npm runtime deps, fonts, embedded Python packages)
- SOURCES.md: GPL §3(b) written source offers for Pandoc 3.9.0.2,
ffmpeg-static's GPL build, and the PyInstaller bootloader; LGPL relinking
note for libvips
- third-party-licenses/: canonical GPL-2.0, LGPL-2.1, MPL-2.0, Apache-2.0,
OFL-1.1, PSF-Python texts
- Help > Third-Party Notices & Licenses: in-app viewer for both documents
- README: 'Bundled Dependencies, Legal Notices & Credits' section
Hardening:
- download-tools.js now SHA-256 pins every artifact, verifies after
download AND against the cache on every run, and hard-fails on mismatch
(closes security finding D6)
Large tools intentionally not bundled (documented): LibreOffice,
MiKTeX/TeX Live, ImageMagick, PlantUML+JRE, Calibre.
637/637 tests green; lint clean; clean boot; bundled binary verified.
- File → Import with MarkItDown (Any Format)…: PDF, DOCX, PPTX, XLSX,
Outlook .msg/.eml, EPUB, images, CSV/JSON/XML, ZIP (audio/OCR via the
[all] extras) — verified live against HTML, XLSX (our own exporter's
output), and PDF fixtures
- Command auto-resolution with caching: markitdown binary → python -m
markitdown → python3 -m markitdown
- SEC-1 argv discipline (execFile only, user paths never through a shell),
50MB cap, 120s timeout, sanitized errors that surface markitdown's own
"pip install 'markitdown[pdf]'" hints for missing format extras
- Output lands next to the source as <name>.md (numeric suffix, never
overwrites) and opens in a new tab; markitdown:available/convert IPC
allowlisted for renderer flows
- Help → Dependencies lists MarkItDown; README/UPDATES updated (v4.6.1)
12 new tests (629 green); lint clean; clean app boot
