+
+A 100% match is the goal, but **how** we get there matters just as much.
+
+- Do not use "any means necessary" to force a match if it results in unreadable or unnatural code.
+- Always think about what the original code probably looked like and write it that way.
+- Even if a function matches 100% binary-wise, it is not "correct" if the source is unreadable or contains logic that no human developer would have written.
+- If you find a stubborn mismatch, look for a more natural C++ expression or a different architectural pattern instead of resorting to opaque hacks.

+- When a helper is doing address arithmetic, prefer `intptr_t` / `uintptr_t` or byte-pointer (`reinterpret_cast<char *>`) math over plain `int` parameters or integerized pointer subtraction.
 - Inline assembly is acceptable when it is needed to preserve dead-code compares, ordering, or other compiler behavior that source alone cannot reproduce.

+
+- In headers, keep the guard / `EA_PRAGMA_ONCE_SUPPORTED` block before any project `#include`; do not place includes ahead of `#pragma once`.
+- Use `#ifdef MACRO` / `#ifndef MACRO` for presence checks. Reserve bare `#if MACRO` for cases where you really need the macro's numeric value.
 
 ### Forward declarations and local prototypes
 
 - Prefer including the owning repo header over adding a local forward declaration for a project type.
 - If the repo already has a header declaration/definition for a type, include that header instead of redeclaring the type locally.
 - If the repo only has an empty or stub owner header, and line info / surrounding source clearly points at that header's subsystem, prefer populating that owner header over leaving a recovered project type declaration inside a `.cpp`.
 - Only keep a local forward declaration when no canonical repo header exists yet and you have verified that the ownership is still unresolved.
+- Likewise for project free functions: if a declaration is shared across translation units, move it into the owning header instead of leaving ad-hoc local prototypes in `.cpp` files.
 - Prefer moving helper template declarations next to their real use site instead of leaving them in an unrelated file.

 - Preserve recovered member names, types, order, and offset comments. Do not invent placeholder members named `pad`, `unk`, `unknown`, or `field_XXXX` for game code just to make a layout compile.

 ### Dense local code
 
 - Expand dense one-line helper structs, declaration blocks, and function bodies in non-match-sensitive files into normal multiline formatting.
+- In low-level headers, prefer normal multi-line bodies for touched inline operators and accessors instead of stacking `{ return ...; }` on one line, unless the surrounding file clearly uses intentional placeholder one-liners.
 - Prefer readable blocks over stacked one-line statements when behavior does not depend on exact source shape.
+- In touched validation/parsing code, prefer explicit min/max or boundary checks over equivalent magic-constant arithmetic when the clearer form still compiles to the verified result.
+- In parser/state-table code, prefer named enums and enum-typed state variables over anonymous integer state codes when that rewrite is verified safe.
+
+### Recovery markers
+
+- Remove stale recovery markers such as `// TODO`, `// UNSOLVED`, or `// STRIPPED` when the touched code is now implemented or understood.
+- If a marker still needs to stay, give it short context such as ownership uncertainty, a Dwarf caveat, a platform/config note, or a scratch/link reference. Avoid bare marker-only comments.
+- Do not leave `// TODO` hanging off a declaration or helper you just implemented; either finish the thought or remove the marker.
 
 ### Uncertain ownership
 
 - If a declaration or global clearly compiles but its original home is uncertain, add a short TODO comment instead of inventing structure you cannot justify yet.
 - When ownership matters, verify it with `decomp-workflow.py`, `decomp-context.py`, and `line-lookup` before moving code.
 
+### Readable helper extraction
