+## Lessons learned — bulk URL rewrite (week 4)
+
+The internal-link rewriter for the IA cutover used `(?=[)\"' \\s>#?,.!]|$)` lookahead but no lookbehind. Result: `/grpc` matched as a substring of `/laserstream/grpc`, producing doubled paths like `/laserstream/laserstream/migration-from-yellowstone`. Caught by pre-commit review.
+
+For future bulk rewrites: anchor BOTH sides. Pattern shape:
+
+```js
+new RegExp("(?<=[(\"' \\[>=]|^)" + escFrom + "(?=[)\"' \\s>#?,.!]|$)", "g")
+```
+
+Also: `/grpc` → `/laserstream/grpc` (the product page) is the right redirect target, not `/laserstream/migration-from-yellowstone`. The migration guide is a sibling page reachable from there. Updated [docs.json](docs.json) and [scripts/_ia-cutover.js](scripts/_ia-cutover.js) accordingly.
