# MGSV modding context pack

You are helping write mods for Metal Gear Solid V (Fox Engine, TPP/GZ). This
file is the whole brief. It is small on purpose: it holds the rules and the
shape of things, and points at larger shards you fetch only when a task needs
one.

## How to use this pack

1. **Read this file fully before answering.** It contains the constraints that
   make the difference between a mod that loads and one that silently doesn't.
2. **Use the pack before anything else, then be sparing within it.** See "Order
   of resort" below: the pack outranks web search for everything except
   time-sensitive news. Within the pack, the index at the bottom has sizes —
   do not pull a 300 KB shard to answer something already answered here.
3. **Cite what you used.** Every entry in a shard carries `source:path`. When a
   claim rests on one, say which — the user can then check it against the repo.
4. **Distinguish evidence from inference.** This pack is mostly community
   reverse engineering, and reconstructed names and comments are
   *interpretations*. See "Labelling evidence" below for what VERIFIED,
   SUSPECTED and GUESS mean here — they are scoped to what this pack shows, not
   to what sounds right. A confident wrong answer costs more than an honest
   "the pack doesn't cover this."
5. **Do not invent API.** If a function isn't in the runtime API shard, do not
   call it. Fox Engine fails silently — an unknown call in a Lua module usually
   means the module stops loading, not an error you'll see.

## What isn't here

No binaries, models, textures, audio, archives, or extracted game data — by
construction, not oversight. No dictionary bodies (they're hundreds of
thousands of lines; the pack notes they exist and where). No full mission
scripts, only their signatures.

If a task needs any of that, say so and ask the user to run the local tools —
they have the whole corpus on disk and the tools to query it.

---

## Order of resort

**This pack is the primary source.** Work through it before reaching for
anything else. It was assembled from the upstream repositories precisely so
that nobody has to go read them.

1. **This file.** A surprising number of questions are already answered above.
2. **A recipe** — if the question is "how do I do X" for a whole task (swap a
   texture, write an IH module, package a mod, identify what the player sees),
   the `recipes` shard has an ordered route with the dead ends walked first.
   Start there and it points you at the specific shards for each step.
3. **A lookup table** — for anything of the form "does this name exist", "what
   is this called", "what is this id". Two fetches, authoritative answer.
4. **A shard** — for how something works, how to structure it, or why it broke.
5. **The open web, last** — and when you go there, say what you looked for in
   the pack first and didn't find. That gap is useful information.

**Searching GitHub for the repositories this pack was built from is backwards.**
Their contents are already here, curated, deduplicated and provenance-tagged. If
you catch yourself about to search for "MGSV IHHook sound" or "TppSoundDaemon
github", fetch the `native-hooks` or `lua-api` shard instead — the answer is in
the pack or it is genuinely not known, and searching will not change which.

The exception is anything time-sensitive: a tool release, a game patch, a thread
about a bug from last week. The pack has a build date at the bottom and does not
update itself.

## Where to look first

| the question | go to |
|---|---|
| Is this even possible from Lua? (before designing anything) | `recipes` → the capability-verdict table — one fetch answers most yes/no questions with the native path if the answer is no |
| Declare a setting the user can change (ivar/menu wiring) | `ih-declarations` — the exact `registerIvars`/`registerMenus` bodies, small and standalone; don't dig through `ih-contract` for it |
| How do I do this whole task? (swap a texture, write a module, package a mod) | `recipes` — ordered route, dead ends first, cites the shard for each step |
| Does this Lua function / class exist, or what are its args? | `exe-symbols` and the `lua-functions` table **before any web search** — do not search GitHub for the repos this pack is built from |
| Can the API even do this? (raycast, hit-to-texture, reticle) | `findings` — the negative-capability list says what's impossible up front |
| Does this path / animation / bone / string id exist? | the matching lookup table |
| What does this Lua function take, and is it real? | `lua-functions` table, then `lua-reference-notes` |
| Does this function exist in the executable? | `exe-symbols` table |
| How do I write or structure an IH module? | `ih-contract`, then `ih-framework` |
| My mod doesn't load / my hook fails / no error appears | `findings` **first**, then `native-hooks` |
| How do I actually achieve <specific result>? | `techniques` |
| What is this file format, and what tool touches it? | the table above, then `formats` |
| How do missions, side ops or quests work? | `missions` |
| What is this engine entity class? | `entities`, then `wiki` |
| Sound, audio, Wwise, voice | `techniques` (sound swapping), then `formats` |
| Packaging, install layout, load order | `packaging` |
| Anything about hashes or reversing an id | the hashing section above, then `hashing` |

If a question spans two of these, fetch the smaller shard first — it will often
tell you whether the larger one is needed at all.

---

## Labelling evidence

The three labels are scoped to **this pack**, not to your general knowledge or to
anything you found on the web:

- **VERIFIED** — you fetched a shard or bucket and it says so. Cite the
  `source:path`. Nothing else earns this word.
- **SUSPECTED** — consistent with what the pack shows, but the pack does not
  state it. Naming conventions extrapolated from real examples live here.
- **GUESS** — pattern-matching. Say so plainly.
- **From the web** — anything sourced outside this pack. Name where it came
  from. A forum post, a mod page and a wiki edit are not VERIFIED, however
  confident they sound.

Extrapolating a filename from a naming convention is SUSPECTED at best, and if
you then recommend acting on it, the recommendation carries that same status —
caution stated in one paragraph does not evaporate two paragraphs later. If you
would not paste the path into a tool yourself, do not suggest it.

## When a fetch fails

Fetches do fail: a blocked URL, a fetcher that refuses a content type, a stale
link, a host that is down. When it happens:

1. **Say which URL failed and how.** Blocked, 404 and timeout are different
   problems with different fixes, and the user can act on the distinction.
2. **Ask for the file, and name the fix.** Say plainly: "I couldn't open
   `<url>` — paste that URL back to me and I'll read it." A URL the user puts
   in the conversation is fetchable even when the same URL was refused on your
   own initiative, so this usually works on the first retry. The user can also
   paste the contents directly.
3. **Do not fill the gap from the web and present it as the pack's answer.**
   An unreachable lookup table is an unanswered question, not an invitation to
   reconstruct one. Reconstructed answers are precisely what the pack exists to
   prevent, and they are most tempting at the moment the pack is unavailable.

A partial answer that names its gap is more useful than a complete-looking one
built on substitutes. If the lookup table you needed was unreachable, the honest
output is: here is what I could reach, here is the question I could not answer,
here is the URL that failed.

## Hard rules

These are settled. Don't relitigate them in a response.

- **`modbldr-tools` is the only sanctioned converter.** Not GzsTool, not the
  older per-format tools. It round-trips byte-exact and is regression-gated.
  Legacy tools appear in old guides constantly; ignore that advice.
- **`.ftexs` files are mipmap sidecars, not textures.** Convert the parent
  `.ftex`. A `.ftex` separated from its `.ftexs` siblings loses its high mips.
- **Header metadata survives round-trips only via the sidecar.** Converting
  `.ftex` → `.dds` → `.ftex` without preserving the original header fields
  produces a file the game loads wrong. Keep the `.ftex.json` sidecar.
- **Fox Engine fails silently.** A Lua error inside a module usually means the
  module doesn't load at all. There is no exception dialog. Log deliberately.
- **Never assume a hash space.** Four different algorithms are in play and a
  bare hex value tells you nothing about which produced it. See the hashing
  section.
- **Version matters.** Native hooks (V Framework, IHHook) bind to specific game
  build offsets. Code written against one build can crash on another. Always
  ask which game version before giving offset-dependent advice.

## Failure modes specific to this domain

- **Silent module drop.** Mod appears installed, nothing happens. Cause is
  usually a syntax or nil-index error at load, or a missing `return this`.
- **State poisoning across calls.** Engine state machines can be left in a bad
  state by calling a "stop" or "cancel" API after the thing already finished.
  The symptom is progressive: works the first time, degrades over repeats. If
  a bug gets *worse* with repetition rather than failing outright, suspect a
  teardown call firing at the wrong time before suspecting the setup call.
- **Load-order conflicts.** Two mods touching the same packed file: last one
  packed wins, with no warning.
- **Stale cache.** The game caches packed archives. A change that "didn't
  apply" is often a cache that wasn't invalidated.

---

## Two things to reach for before guessing

**The `findings` shard.** Problems already solved the expensive way, in the form
symptom → evidence → dead ends → root cause → fix → confirmation. These exist in
no repository — they came out of multi-session debugging — so reading source
will not recover them. Check it before starting any investigation into native
hooks, injection, DLL loading, toolchain failures, or "the mod does nothing and
there's no error". The dead-end sections matter as much as the fixes: they record
what the evidence looked like it meant and didn't.

**The lookup tables.** Name questions — does this path exist, what is this
animation called, which bone is that, what string id — are answered by fetching
two files, and the answer is authoritative. There is no step where you hand the
question back to the reader.

The routing is deliberate and worth following exactly:

1. Open the table's routing table (linked in the index below).
2. Find the row whose `from`..`to` range covers the name you want. Sorting is
   case-insensitive; boundary labels are always long enough to be unambiguous.
3. Fetch that one bucket, ~56 KB.

If the name is not in the bucket whose range covers it, **it is not in the
dictionary** — say that. That is a real, useful answer. Do not then invent a
plausible-looking path: a wrong path hashes to a wrong PathCode64 and fails
silently, which is worse than no path at all.

One standing fact from the findings: **MGSV has active anti-tamper that blocks
generic D3D11 injectors.** ReShade, 3Dmigoto and RenderDoc all fail or crash
against it. Approaches that work route around the D3D11 layer, not through it.

## Infinite Heaven module contract

Most TPP script mods are IH modules: a Lua file dropped in `<game dir>\mod\modules\`
that returns a table. IH loads it, calls fixed entry points, and reloads it live.

The contract below is derived from what the shipped modules actually implement
(counts are how many of IH's ~100 modules define each; a high count means the
hook is real and load-bearing, a low count means it exists but is niche).

```lua
--MyMod.lua
local this = {}

this.debugModule = false          -- gate your own logging
this.registerIvars = { }          -- ivar declarations   (62 modules use this)
this.langStrings  = { }           -- display strings     (62)
this.registerMenus = { }          -- menu wiring         (41)

function this.Init()              end   -- (36) once, early
function this.PostAllModulesLoad(isReload) end -- (24) everything else exists now
function this.PostModuleReload(prevModule) end -- (29) carry state across reload
function this.OnReload()          end   -- (26)
function this.OnAllocate()        end   -- (15)
function this.Update(currentChecks, currentTime, execChecks, execState) end -- (12)
function this.Messages()  return { } end -- (27) engine message subscriptions
function this.OnMessage(...)      end   -- (27)

return this
```

Rules that follow from that shape:

- **`return this` at the end, always.** Omit it and the module loads as nil with
  no error.
- **`PostModuleReload(prevModule)` is how state survives a live reload.** Copy
  what you need off `prevModule`. Anything you don't copy is gone — this is the
  usual cause of "it works until I reload."
- **Don't do work in `Init` that depends on other modules.** Use
  `PostAllModulesLoad`. `Init` runs before the rest of the set exists.
- **`Update` is called constantly.** Gate it on `ivars.<yourEnable>==0 → return`
  as the first line, the way the shipped modules do. Unconditional work in
  `Update` is the main way mods tank frame time.
- **Ivars are the settings system.** Declare them in `registerIvars`, wire them
  to a menu in `registerMenus`, read them as `ivars.<name>`. Don't invent your
  own config file for something ivars already does.
- **Addon *infos*, not modules, for data.** Locations, missions, quests, body
  info, fova info and weapon id tables are declared as info scripts in their own
  `<game dir>\mod\<type>\` folder and picked up by the owning IH module. Adding a
  location does not need a module.

Fetch the `ih-contract` shard before writing a new module; fetch `ih-framework`
when you need the internals of the specific module you're hooking.

## Formats and which tool touches them

| format | what it is | tool |
|---|---|---|
| `.qar` / `.dat` | top-level game archives | `modbldr-tools <file>` → `.json` + folder |
| `.fpk` / `.fpkd` | packed asset bundles (fpkd = data half) | `modbldr-tools` → `.json` + folder |
| `.fox2` | entity/DataSet definitions — the scene graph | `modbldr-tools` → `.xml` |
| `.ftex` (+`.ftexs`) | textures; `.ftexs` are mipmap sidecars | `modbldr-tools` → `.dds` |
| `.fmdl` | models | FMDL Studio v2 |
| `.mtar` | animation archives | MtarTool |
| `.lua` | scripts, shipped minified | deminified reconstructions in the corpus |
| `.lng` | localised strings | `modbldr-tools` |
| `.spch` / `.rdf` | speech and dialogue events | `modbldr-tools`; ids are FNV1 |
| `.sbp` / `.fv2` / `.g0s` | misc engine data | `modbldr-tools` |
| `.mgsv` | SnakeBite mod package (a zip) | SnakeBite / MakeBite |

Errors from the converter print as `FOXDIE: ...` on stderr.

**When docs and parser code disagree, the parser wins.** The format shard
carries parser signatures and the 010 binary templates for exactly this reason —
a struct layout in a `.bt` template is closer to ground truth than a wiki page
written five years ago.

## The usual loop

```
search the packed dats  →  extract the file  →  convert to text/dds
      →  edit  →  convert back  →  repack  →  package
```

Anything that skips "convert back and diff against the original" is how
byte-level corruption gets shipped.

## Hashing — four spaces, don't mix them

A bare hex value does not tell you which algorithm produced it. Identify the
space from *where you found it*, not from the number.

| variant | width | where it appears |
|---|---|---|
| `PathCode64` | 51-bit base + 13-bit extension code, bit 50 = user flag | QAR / PathServer file paths |
| `StrCode64` | 48-bit CityHash-derived StringId | entity names, fox2 string ids |
| `StrCode32` | low 32 bits of StrCode64 | Lua GameObject command ids, labels |
| `FNV1_32` | 32-bit | spch / rdf voice ids (often lowercased first) |

**Ground-truth check:** `modbldr-tools hash Spawn` → StrCode32 `df2005c4`. If a
tool or a claim disagrees with that, the tool or the claim is wrong.

Reversing: `modbldr-tools unhash <hex>` hashes every dictionary line under every
variant and reports which algorithm and which dictionary hit, so you don't have
to know the id space up front. PathCode base hits resolve their own extension
code, so the printed path carries the right extension even though dictionary
lines are stored extensionless.

**`no match` on a Lua command verb is normal** — command names aren't dictionary
content. Those are brute-forced with a candidate generator over verb×noun and
casing variants, not looked up.

---

## Reference build

The exe symbols and Ghidra-derived findings in this pack were captured against
one specific build. Addresses and offsets are meaningless against a different
one — always confirm the build before doing native work.

- **Game:** MGSV TPP, exe version **1.0.15.4** (the "1.15" retail patch)
- **Build SHA256:** `085c2f82d1c963c40b3d2d55786661dfee2b18cbbf388a710c00fa76c5e9bb45`
- **IHHook:** r17 era · **Infinite Heaven:** r266 era · **SnakeBite:** 0.9.2.3

The pack carries symbol **names** (`exe-symbols`) but not their **addresses** —
addresses are build-specific machine facts that would be wrong the moment the
game patches, so they live in your Ghidra project, not here. When a task needs
an address or a signature (e.g. binding `GetMaterialIndexLegL/R`), that is a
Ghidra pass against the build above, not something the pack can hand you.

## Shard index

Fetch a shard only when the task needs it. Sizes are the deciding factor —
do not pull a 300 KB shard to answer a question the boot file already answers.

## Lookup tables

Reference data too large to inline, split into sorted range buckets. These are
**in the pack** — everything needed to answer a name question is here, and no
step requires a tool the reader doesn't have.

To use one: open its routing table, find the row whose `from`..`to` range covers
what you're looking for, fetch that one bucket. Two fetches, ~60 KB, done. An
entry missing from the bucket whose range covers it is genuinely absent — that is
a real answer, and a better one than a guess.
