gmail: strip Outlook reply headers without inline / wrappers by KrisBraun · Pull Request #152 · plotday/plot

KrisBraun · 2026-05-27T19:34:18Z

Summary

stripQuotedReply previously required each "From:/Sent:/To:/Subject:" label to be wrapped in  or . Corporate Exchange/Outlook variants (e.g. Gowling-style MsoNormal, , plain  headers) don't use those tags, so reply chains leaked into synced notes.
Adds a tag-agnostic fallback findOutlookHeaderTagAgnostic() that replaces every HTML tag with same-length whitespace (offsets stay aligned with the original) and anchors each label at a structural boundary — start-of-string, a real newline, or 3+ whitespace chars (the smallest gap any block tag produces when collapsed). That anchor keeps user prose mentioning From/Sent/To/Subject inline from false-matching.

Test plan

Unit tests for the four common Outlook variants pass (workers/api/src/twist/tools/__tests__/gmail-quote-strip.test.ts in the parent repo covers bold-wrapped, no-inline-bold, , and prose false-positive cases — 6 tests, all green).
Re-sync a corporate-Outlook reply thread and verify the quoted block is stripped.
