@@ -4,66 +4,19 @@ This document contains specifics about the workings of the Odin programming
 language, dynamic linking and state management design patterns. These are
 tested and validated findings, for continued reference by me.
 
-## Compiler
-
-Odin's compiler is demand-driver: a procedure's body is only semantically
-analyzed when the proc is actually referenced.
-
 ## Dynamic Library Memory
 
 When a program loads in a dynamic library, what happens with package globals?
 
 Findings (macOS):
-- Package globals are shared between modules, but only indirectly
+- The package globals are shared between the host and the lib
-  - This is due to the dynamic linker merging symbols into a (single) flat namespace
-  - Practically this means the lib's unset package globals get shadowed by the hosts'
 - After hot reloading the lib, the memory of the packge is not refreshed,
   it keeps pointing to the package global of the host
 
-Findings (Windows):
+The clanker states this is due to "flat-namespace symbol interposition".
-- Package globals are not shared between modules, they have their own copy
 
-Findings (Linux):
+Linux "ELF has symbol preemption: when resolving references, ld.so searches
-- Package globals are not shared between modules, they have their own copy
+globals scope in order — executable first, then loaded shared objects".
 
-Conclusion: avoid package globals, or pass pointers to the dynamic library so
+Windows PE has no interposition at all, every module (exe and each DLL) has its
-it can match its package globals with the host module.
+own symbol table.
-
-## Dependency Patterns
-
-1. Strict layering, only call downwards. If two modules need each other, one of
-   the modules is in a wrong layer. Move it, or extract the shared part into a
-   lower layer.
-2. Dependency inversion: if required, define an interface in the lower layer,
-   upper layer registers itself.
-3. Dependency Injection: Prevent dependencies via data, over includes. Pass what
-   a function needs as arguments instead of reaching another module's state.
-4. Events instead of callbacks both ways If A and B would call each other,
-   have A push events into a queue and B consume them. Neither module includes
-   the other; they only share the event type (which lives in a lower layer).
-5. Merge or split as a last resort, if two modules genuinely can't be untangled.
