+### Patch Changes
+
+- [#58](https://github.com/Intentface/intentface-chat/pull/58) [`9f74772`](https://github.com/Intentface/intentface-chat/commit/9f747721d26299de9a15f7983e875ec9c8df3ad3) Thanks [@rpvilo](https://github.com/rpvilo)! - Fix two quadratic-backtracking regexes that could hang the browser.
+
+  `parseChipSegments` is the serious one, because message text is untrusted — it
+  arrives from the model. The chip token pattern had two independent blowups. A long
+  run of `[` with no closing bracket made the label group consume to end-of-string,
+  fail, backtrack over every position, advance one character and repeat: 355ms at
+  32k characters. Worse, `[a](chip:x:` repeated with no `)` anywhere did the same
+  through the value group from many start positions at once: 264ms at 88k
+  characters. Both grow quadratically, so a large message could hang a tab for
+  seconds.
+
+  Every character class now excludes `[`, so no group can consume past the next
+  one and the work per start position is bounded by the gap to it. Safe for
+  anything `encodeChipMarkdown` produces — values are `encodeURIComponent`-escaped,
+  queries come from `URLSearchParams`, prefixes are short identifiers — and labels
+  containing raw brackets never parsed under the previous pattern either.
+
+  `detectActivePrefix` had the same shape via `/\S*$/`, which retries from every
+  position when the text ends in whitespace. It runs on every keystroke, so pasting
+  a large single-token blob froze the editor — 16 seconds for a 200k-character run.
+  Replaced with a backwards index scan, which is linear, allocation-free, and
+  returns identical results.
+
+  Both are covered by regression tests asserting a time budget that the previous
+  implementations exceeded by two orders of magnitude.
