## What's Missing (TODO)
* **Saving/Loading:** The tape and annotation arenas are purely in-memory and are lost when the program closes.
* **Expanded Instruction Set:** The JIT only knows a handful of primitives (`SWAP`, `MULT`, `ADD`, `FETCH`, `STORE`, `DEC`, `RET_IF_ZERO`, `PRINT`). It has no support for floating point, stack manipulation for C FFI, or more complex branches.
* **Robust Dictionary:** The current dictionary is a simple array that is rebuilt on every compile. It doesn't handle collisions, scoping, or namespaces.
* **Expanded Instruction Set:** The JIT only knows a handful of primitives (`SWAP`, `MULT`, `ADD`, `FETCH`, `STORE`, `DEC`, `RET_IF_ZERO`, `PRINT`). It has no support for floating point or more complex branches.
* **The FFI Bridge:** The system needs a macro (like Onat's `CCALL`) to align the `RSP` stack to 16 bytes and map the 2-register data stack/globals into the Windows C-ABI (`RCX`, `RDX`, `R8`, `R9`) to call WinAPI safely from the JIT.
* **Implicit Definition Boundaries (Magenta Pipe):** Definitions should not need explicit `begin`/`end`. A definition token should implicitly cause the JIT to emit a `RET` to close the prior block, and an `xchg rax, rdx` to rotate the stack for the new block.
* **x68 Instruction Padding:** The JIT currently emits variable-length instructions (`emit8`). It needs to pad every logical block/instruction to exact 32-bit multiples using ignored prefixes or NOPs to perfectly align with the visual token grid.
* **O(1) Dictionary & Visual Linking:** The current dictionary is a simple string-matched array rebuilt on compile. It needs to transition to a true "visual linker" where visual tokens store the absolute source memory indices, resolving locations instantly at edit-time.
* **Annotation Editing:** Typing into an annotation just appends characters. A proper text-editing cursor within the token is needed.
