+Three of these are not fixable from inside this repository, and each costs
+something here. They are filed in both places, because the fix is there and the
+bill is here. The fourth turned out not to be blocked at all:
 
 | Here | Upstream | What it costs |
 |---|---|---|
-| #2 | libakerror | The unlocked error pool, **which is what makes this library single-threaded**. The threading and socket wrappers cannot be written until it is resolved |
+| #2 | — | **Corrected while filing.** The unlocked error pool is a property of the libakerror this repository *pins* (1.0.0), not of libakerror (2.0.1, which locks it). `libakgl` and `akbasic` are both on 2.0.1. The work is a submodule bump and the verification that goes with it, not a wait |
 | #3 | libakerror | `IGNORE()` leaks a context, so `aksl_tree_iterate` open-codes log-then-release in four lines that should be one |
 | #4 | libakerror | The `coverage` target is not namespaced when embedded, so `-DAKSL_COVERAGE=ON` fails to configure and `CMakeLists.txt` shadows `add_custom_target` to work around it |
 | #5 | libakerror | No `akerrorConfigVersion.cmake`, so `find_dependency(akerror)` cannot ask for the 1.0.0 floor |
