src/css/compat.rswas converted from a generatedmatchto a data table (equal-or-faster, verified) — but it's no longer regenerable bybuild-prefixes.jsas-is. If we'd rather keep it generator-owned, I can revert that one commit's hunk or update the generator to emit the table form.bun add/update, postgres NoticeResponse short-length tolerance, macro-map parsing, JSON5/YAML space handling, SQL driver failure timing, pool slot guards — has been reverted to match main exactly. Where a dedup could not preserve behavior, the dedup itself was reverted.#[allow(dead_code)]insrc/router/lib.rs; resolved by deleting the orphaned cfg(test) fixture scaffolding (266 lines, plus its now-unused dev-dependency), not by updating the inventory.bunx.test.ts"requires node 24" failure is pre-existing on main; the darwinAsyncLocalStorage-trackingfs-watch exit segfault is the known FSEventsLoop shutdown race (fs.watch(macOS): make FSEventsLoop Sync and retain the CFRunLoop across shutdown #30758 — identical stack, fault address 0xC, filed before this branch existed; every file in that crash path is byte-identical to main here).
