+## [0.49.1] - 2026-08-03
+
+- punk::libunknown 0.2.4: deep tm discovery (`register_all_tm`, used by
+  `dev lib.search`) now skips the G-155 workdirs `_mint` and `_bake`
+  alongside legacy `_build` in both the directory walk and the tm-file
+  filter - loose staged `.tm` files in `<srcdir>/_mint` were being
+  registered as junk `_mint::*` modules.
+- punk::tcltestrun 0.3.1 + runtestmodules.tcl: the unbuilt-modpod scan's
+  subfolder excludes likewise missed the `_build` -> `_mint` staging
+  rename - staged pods were registered as bogus `*::_mint::*` modules in
+  test interps; now `-exclude-paths {**/_build/*** **/_mint/***}` (test
+  tooling - listed for the record, not itself a bump trigger).
