fix(editor): flush on quit and scan tags once - #483
Conversation
Closing the window could drop the last debounce. Main now waits for each renderer to persist. Hashtags go through scanMarkdown so fences and ~~~ stay out of the tag list. fetchUrlTitle uses the typed IPC registry.

If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based reviews. How do review limits work?CodeRabbit enforces per-developer PR review limits within each organization. For paid Pro and Pro+ reviews, CodeRabbit uses a developer's included PR review attempts over the past 7 days to set the current hourly allowance. At typical activity levels, the full plan allowance applies. Higher sustained activity can lower the allowance until earlier attempts leave the 7-day window. Please refer docs for additional details.

Markdown tag extraction
Estimated code review effort: 4 (Complex) | ~60 minutes Merge Risk: 🟠 High · up to The PR improves shutdown saving and metadata scanning, but the current implementation can still lose newer or empty note content, skip saves during window teardown, send redirected URL-title requests to private services, and produce incorrect titles or tags. These security and data-integrity risks make the PR unsafe to merge until corrected. Sequence Diagram(s)sequenceDiagram

If a save for

In `@apps/desktop/src/main/handlers/editorHandlers.ts`:
- Around line 17-20: Update the fetch flow using isBlockedFetchHost to disable
redirects with redirect: 'error', and validate the resolved connection address
before connecting so private or loopback DNS results are rejected and DNS
rebinding is prevented. Add coverage for redirect responses and private DNS
resolution while preserving the existing timeout, headers, and hostname checks.
In `@apps/desktop/src/main/handlers/htmlTitle.ts`:
- Around line 5-10: Update the title decoding logic around the raw value to use
one replacement callback over original HTML entity matches, ensuring each entity
is decoded only once and preserving inputs such as < as <. Add
a regression test covering the nested encoded entity case.
In `@apps/desktop/src/main/windows/flushEditors.ts`:
- Around line 7-26: Update flushWindow to catch webContents.send failures after
the liveness check and always resolve its flush promise, then await
Promise.allSettled(windows.map(flushWindow)) before shutdown. Ensure
acknowledgement tracking waits for every required save operation per window,
rather than removing the listener after only the first shared flush ID
acknowledgement.
In `@packages/markdown/src/scan.ts`:
- Around line 113-120: Update the scanner around TAG matching to skip tag
extraction whenever atx is present, while preserving existing extraction for
non-heading content. In packages/markdown/tests/scan.test.ts lines 27-40, add a
hashtag to the heading fixture and assert that the heading hashtag is absent
from the scan result.
Apply the same fix in `@packages/markdown/tests/scan.test.ts` around lines 27 -
40: The test fixture must contain a hashtag in the heading to detect the scanner
regression.

Decode HTML entities in one pass. Do not follow title redirects. Wait for every window flush even if one send throws. Do not treat hashtags in ATX headings as tags.
# Test #javascript is the existing extractTags contract. Skipping ATX lines dropped those tags.

A stale debounce save was wiping newer unsaved text, and an empty note never flushed because "" is falsy.
The old ([^<]+) capture dropped titles like "C < C++".
