Let me check the current state — the recent commits mention a dungeon, so let me see exactly what was done.

• Bash git log --oneline -8 && echo "---FETCH---" && git fetch 2>&1 | tail -3 && echo "---STATUS---" && git status -sb 1.8s 626 B

• Bash sed -n '1,60p' memory.md 2>/dev/null | grep -niE "dungeon|forge|hub|location|M2|M3|additional" 728ms 7.8 KB

Yes — the dungeon is in. Here's exactly where things stand:

**What was added** (commits `9b36f20` → `26ab597`, 2026-06-24):
- Adopted **`Dungeon_Forge/Levels/Dungeon_Forge_Main`** as the first real location — the dungeon-pack's fully-built demo map (6,836 actors, has `PlayerStart_3`). You walked it in first-person PIE and liked it.
- Made it **playable** by setting a World Settings **GameMode override = `BP_ThirdPersonGameMode`** (so it spawns our `BP_FirstPersonCharacter`) and saving. The map is LFS-tracked; committed two-step (assets `85d08e1` → root pointer `9b36f20`).

**"Alongside L_Hub" — almost, but not linked yet:**
- Both maps exist and are both playable, but they're **independent right now**. `L_Hub` is still the *main spawn / launch map* (`DefaultEngine.ini` unchanged) — the game still boots into the hub. The dungeon is playable only if you open it directly.
- The **hub→dungeon link is deferred** by design. Connecting them (portal in the hub that streams the dungeon in, co-travel gating, return-to-hub) is the **zone framework — M4**, with the dungeon's actual perceptual split being **M5**. We're currently sitting just past **M2** (the replicated `BP_HubButton` passed), with **M3 (the perception spine)** as the next milestone.

So: the dungeon is committed, backed up, and walkable — but it's a standalone location, not yet wired to the hub. That wiring is the next big chunk of work (M3 spine → M4 portal/streaming).

One caveat already noted in `memory.md`: `Dungeon_Forge_Main` is a vendor kitchen-sink demo map — for a shippable zone we'd carve out a section rather than ship the whole 46 MB map.

Want me to start on the hub→dungeon link (the M4 streaming/portal work), or focus on M3 (the perception-profile spine) first? I'd recommend **M3 first** — it's the make-or-break spine and M4's transitions are cheaper to build once a profile is assignable.

I'll probe whether nwiro (the editor automation) is reachable this session, then check the actual state.

• ToolSearch nwiro level info pie game state 5ms 293 B

• Bash bash scripts/nwiro-health.sh probe 2>&1 | tail -5 2.6s 36 B

• ToolSearch nwiro get_level_info pie_get_game_state open_level get_level_actors 4ms 32 B

nwiro's HTTP endpoint is alive. Let me check whether the actual nwiro MCP tools are wired into this session.

I checked, and here's the situation:

**I can't drive PIE for you this session.** The nwiro HTTP endpoint pings alive (405), but the actual `mcp__nwiro__*` tools aren't wired into this session — MCP servers only connect at session start, so even though the socket is up now, I have no editor-automation tools loaded. So I can't press Play and look for you directly. But I can tell you exactly why you're not seeing the dungeon, because it's expected given how we left things.

**Why the dungeon doesn't show up in PIE:**

PIE plays **whichever level is currently open in the editor**, and the project still boots/defaults to **`L_Hub`** (`DefaultEngine.ini` was deliberately left unchanged). The dungeon is a **separate, standalone map** — `Content/Dungeon_Forge/Levels/Dungeon_Forge_Main` — that is **not linked to the hub** (the hub→dungeon portal is the deferred M4 work). So pressing Play from the hub will only ever spawn you in the hub. There's no door, trigger, or streaming volume connecting them yet.

**To actually see the dungeon in PIE right now**, open it as the active level first:
1. In the editor's **Content Browser**, go to `Content/Dungeon_Forge/Levels/`
2. **Double-click `Dungeon_Forge_Main`** to open it as the current level (this swaps out `L_Hub`)
3. Press **Play** — it has a `PlayerStart_3` at `(-350, -1522, 163)` and we set its World Settings GameMode override to `BP_ThirdPersonGameMode`, so it should spawn your `BP_FirstPersonCharacter` and be walkable.

If it *still* doesn't load after opening it directly, that'd point to something real (e.g. the saved GameMode override or LFS-pulled map not present on your F: tree) — but that's the first thing to confirm.

Two questions so I can be precise:
- When you say "can't see it in PIE" — do you mean it's **not in the level dropdown / Content Browser at all**, or that you press Play **from the hub** and never end up in the dungeon? The second is fully expected (no link yet); the first would be a real problem.
- Do you want me to **wire up the hub→dungeon link** so it's reachable from the hub during play? That's the M4 portal/streaming work — I can plan it out. It does need the nwiro editor tools live, though, so we'd want the editor reconnected first (likely a fresh session so the MCP server attaches).

Let me pull the exact design framing for M3 so I explain it accurately, not from memory.

• Bash grep -niE "perception|profile|M3|spine|split|render|MPC|material param|post.?process|color|shape" DESIGN.md 2>/dev/null … 33ms 4.9 KB

Good — here's the full picture on M3, the perception spine.

## M3 — the goal

**One sentence:** prove that the *same replicated world* can be rendered **differently on each client**, driven by data, so that player 1 and player 2 literally see different things while standing in the same room.

This is the core mechanic of the whole game (the "vocabulary mismatch" — one sees color, the other shape). Everything else is scaffolding around it. The design doc calls it *"the make-or-break test"* — if divergent per-client rendering doesn't work cleanly, the game doesn't exist. M0–M2 proved networking, presence, and server-authoritative state; M3 is the first milestone that's actually *the game*.

## The key principle (and why it's the safe design)

> World state is replicated **identically** to both clients. Only **presentation** differs, and the difference is applied **client-side only.**

So we are **not** hiding data on the server or sending different world states to each player. Both clients have the full truth; each just *renders* it through its assigned "perception profile." This is the **presentation-hiding** stance (already a decided tradeoff): simple, fast, flexible — not cheat-proof, but fine for a trust-based co-op game where both players are cooperating anyway. (Genuine server-gated hiding and actual *world-state divergence* like "Past vs Present" are explicitly **out of scope** for the spine — separate systems for later.)

## What "a perception profile" actually does — 3 layers

A profile can use any or all of these. They escalate in power:

1. **Full-screen post-process** — cheap, global. Desaturate (kill all color), edge-detect/wireframe, blackout, blur, night-vision. Easy to apply to the camera.
2. **Per-actor material override** — swap an actor's material *on this client only*. P1 sees a flat unlit-color blob; P2 sees a white wireframe.
3. **Per-actor mesh / visibility override** — swap the mesh for a featureless proxy, or hide the actor entirely on one client.

**Why all three and not just post-process:** a post-process effect can't *remove* a cue. Killing color is easy (desaturate PP), but a blur or desaturate still leaks **silhouette** — so to truly destroy *shape* for P1 you need a material or mesh swap, not just a screen filter. That's the whole reason the model is layered.

## The pieces I'd build for M3

From the design's architecture section:

- **`PerceptionProfile` (DataAsset)** — the data: a post-process material stack + a set of rules `{actor gameplay-tag → material/mesh/visibility override}`. This is content, not code — new zones author profiles, they don't touch the spine.
- **`PerceptionComponent`** — lives on the local PlayerController/Pawn. `ApplyProfile(P)` sets the camera post-process and iterates tagged actors applying the local overrides; a clear path restores everything. **All local, non-replicated.** This is the candidate to drop to **C++** (it's the spine, and iterating/overriding tagged actors per client is exactly the "fragile in Blueprint" case CLAUDE.md flags).
- **`PerceptionTag` on actors** — so profiles target *classes/groups* by tag, not individual instances. (Likely a gameplay tag or component.)
- **Profile assignment hook** — something tells each client "you are role A / role B" and the client looks up its profile **locally** and applies it. In the full game a ZoneController does this over RPC; for M3 we can stub the assignment (a console command or a simple "assign on play" switch) — wiring it to real zones is M4.

## What "M3 PASSED" looks like

The concrete test, mirroring how M0–M2 were proven:
- Two clients in a listen-server PIE session, in **one shared room** with a few tagged actors.
- Client A gets profile A, client B gets profile B.
- **Client A's view** shows the actors one way (e.g. flat color, silhouettes destroyed); **client B's view** shows the *same actors* the other way (e.g. white wireframe, color stripped) — at the same time, same world.
- Critically: **no attribute leakage** — A's view must not leak shape, B's view must not leak color. (Leakage = one player can solo the puzzle, which kills the design. This is the main risk to watch.)
- The split is driven by the **DataAsset**, not hardcoded — so M5's "Color vs Shape" zone is just authored data, no spine changes.

## Scope boundary (so M3 stays tight)

- **In:** divergent *rendering* of a shared scene, data-driven, client-side, with the no-leak proof.
- **Out:** the hub→zone streaming/portal (that's M4), the actual first zone content (M5), partner-avatar filtering polish, and any real world-state divergence (separate system entirely).

---

A natural M3 demo would essentially be a **stripped-down "Color vs Shape" sandbox**: one room, a handful of tagged colored shapes, two profiles, two windows showing the same objects rendered two different ways. That doubles as the seed for the M5 first zone.

Want me to turn this into an M3 implementation plan — component/DataAsset structure, which parts go C++ vs Blueprint, and the exact PIE test setup? I'd recommend we do that in a fresh session with the nwiro editor tools live, since building it means authoring assets and running PIE, which I can't drive right now.

Before I fan out, I need to know what the code side of this project actually looks like — whether there's a C++ module yet, what the .uproject declares, and what the character/controller classes are that the PerceptionComponent will hang off. Let me scout the working tree.

• Bash cd ~/claude/projects/pair-o-dox && echo "=== top-level ===" && ls -la && echo "=== .uproject ===" && find . -maxdepth 2 … 1.9s 1.5 KB

• Bash cd ~/claude/projects/pair-o-dox && echo "=== Config ===" && ls Config 2>/dev/null && echo "--- DefaultEngine.ini (game/m… 1.6s 365 B

• ToolSearch ue docs unreal engine API symbol search UActorComponent post process material 664ms 335 B

Scouted. Two hard facts shape this:

1. **There's no C++ in this project yet** — no `Source/` dir, it's a pure Blueprint project (UE 5.7, `Pairodox.uproject` lists only plugins, no modules). The design earmarks the perception spine as C++, so M3 is where we'd introduce the *first* C++ module — which converts this from a BP-only project to a C++ project (needs `Source/` scaffolding + a Visual Studio compile on the Windows host).
2. **I can't compile or run anything this session.** nwiro's MCP tools aren't loaded (only the HTTP socket pings), the UE build toolchain is on Windows, and ue-docs MCP is also down. So whatever we produce now, the *compile + in-editor wiring + PIE test* lands next session (editor live), or you run it.

That makes the approach a genuine fork worth your call before I spend a workflow on it — because it changes what's even possible this session:

• AskUserQuestion questions 220.1s 556 B

C++ spine it is. I can't compile this session, so I'll lean on the workflow to do two things I *can't* shortcut without a compiler: **web-ground the UE 5.7 API** (ue-docs MCP is down) and **adversarially review the drafted C++** as a stand-in for the build I can't run. Models that fit: Sonnet for the parallel research + review fan-out, Opus for the one coherent authoring pass, then I assemble and write the files into the repo myself so the interdependent files stay consistent.

Let me kick off the workflow.

The user says ue-docs and nwiro MCP should be up now. Let me re-probe both — the live tool set, not my earlier cached assumption.

• ToolSearch nwiro get_level_info create_blueprint pie_get_game_state create_struct create_enum execute_python 4ms 32 B

• ToolSearch ue docs unreal engine API symbol search UActorComponent PostProcessSettings 2ms 442 B

Let me probe more broadly — the server names might differ from what I'm assuming — and check what's actually configured.

• ToolSearch unreal blueprint level actor material editor screenshot play_in_editor tiletopia 4ms 32 B

• Bash cd ~/claude/projects/pair-o-dox && echo "=== .mcp.json (if present) ===" && cat .mcp.json 2>/dev/null || cat .mcp.json.e… 1.6s 200 B

Now I have the real picture — and it's not what we hoped:

- **ue-docs MCP isn't configured in this project at all.** `.mcp.json` only lists `nwiro` — there's no ue-docs server wired in here, so the `ue` skill has nothing to query. I'll web-ground the UE 5.7 APIs instead.
- **nwiro's socket is alive (405), but its MCP *tools* are not attached to this session.** This is exactly the gotcha in CLAUDE.md: the MCP client only binds at **session start**, and at this session's start `192.168.1.172:5354` wasn't reachable, so no `mcp__nwiro__*` tools ever registered. You fixing the editor *now* doesn't retroactively attach them — `ToolSearch` (which waits for connecting servers) finds zero nwiro tools. **The only fix is a fresh Claude session**, where the client re-attaches at startup with the socket already up.

So this session still can't author editor assets, drive PIE, or compile. But none of that blocks the part I *can* do now: **write the C++ spine source into the repo** (web-grounded for 5.7 correctness) — that needs no editor. The compile + asset authoring + PIE test then happen in a fresh session with nwiro live (or you build on the Windows host).

My recommendation: let me **crack on and produce the full C++ package now** (it persists on disk regardless of restarts), then you restart the session when you want me to do the editor-side authoring + testing. Launching the workflow — Sonnet fans out the web-grounded API research + adversarial review (my stand-in for the compile I can't run), Opus does the one coherent authoring pass:

Good call — ue-docs should be wired into the project. Let me find how it's configured elsewhere so I match the exact server details rather than guessing.

• Bash echo "=== search for ue-docs / ue mcp config across claude tree ===" && grep -rniE "ue-?doc|ue_doc|unreal.*mcp|ue-mcp" ~… 2.8s 23.8 KB

• Bash echo "=== sibling projects' .mcp.json ===" && for f in ~/claude/projects/*/.mcp.json ~/claude/research/*/.mcp.json; do [… 1.7s 855 B

Found it. ue-docs is configured **globally** in `~/.claude.json` (top-level `mcpServers: ['ue-docs', 'tiletopia']`) as a stdio server — from your history: `ue-docs: docker exec -i ue-rag /app/entrypoint.sh mcp - ✓ Connected`. It runs against a local Docker container `ue-rag`. It's just not pinned to *this project*, and the `ue-rag` container needs to be up. Let me grab the exact config and check the container.

• Bash python3 -c "import json,os;d=json.load(open(os.path.expanduser('~/.claude.json')));import json as j;print(j.dumps(d['mcp… 1.9s 133 B

• Bash echo "=== docker availability ===" && command -v docker && echo "--- ue-rag container ---" && docker ps -a --filter "nam… 5.6s 98 B

Everything's in place: `ue-rag` container is **Up (healthy)**, docker works from WSL, and I have the exact ue-docs config. Let me check whether `.mcp.json` is tracked (it holds a machine-specific IP, hence the `.example`), then wire ue-docs in.

• Bash cd ~/claude/projects/pair-o-dox && echo "=== is .mcp.json ignored? ===" && git check-ignore .mcp.json && echo "(ignored … 2.6s 410 B

`.mcp.json` is gitignored (per-machine, because the nwiro plugin rewrites it on editor launch) — the tracked template is `.mcp.json.example`. And the likely reason ue-docs didn't attach this session: the `ue-rag` container only came up **3 minutes ago**, so at session start `docker exec ue-rag` failed. It's healthy now, so a fresh session will catch it.

I'll wire ue-docs into both the local `.mcp.json` (what the new session loads) and the tracked `.mcp.json.example` (so the project documents it). Let me read both first.

• Read /home/megaproxy/claude/projects/pair-o-dox/.mcp.json.example 6ms 129 B

• Read error /home/megaproxy/claude/projects/pair-o-dox/.mcp.json 11ms 104 B

`.mcp.json` doesn't actually exist right now — that's the real reason nwiro never attached this session (it's only ever project-scoped, and there was no project config for the MCP client to read at startup). So I'll create it fresh with **both** servers, and add ue-docs to the tracked `.mcp.json.example` too.

• Write /home/megaproxy/claude/projects/pair-o-dox/.mcp.json 1.9s 150 B

• Edit /home/megaproxy/claude/projects/pair-o-dox/.mcp.json.example 33ms 168 B

Let me validate both JSON files parse cleanly, then commit the tracked example.

• Bash cd ~/claude/projects/pair-o-dox && for f in .mcp.json .mcp.json.example; do python3 -c "import json;json.load(open('$f')… 2.3s 35 B

Both valid. Committing the tracked example (the local `.mcp.json` stays gitignored, as intended):

• Bash cd ~/claude/projects/pair-o-dox && git add .mcp.json.example && git commit -q -m "Wire ue-docs MCP into project (.mcp.js… 4.3s 77 B

Done. Here's where things stand and what to do next.

## ue-docs is now wired into the project

I created `.mcp.json` (the per-machine, gitignored file the MCP client actually reads at startup) with **both** servers, and committed the matching `.mcp.json.example` so the project documents the requirement:

```json
"nwiro":   { "type": "http",  "url": "http://192.168.1.172:5354/mcp" },
"ue-docs": { "type": "stdio", "command": "docker",
             "args": ["exec","-i","ue-rag","/app/entrypoint.sh","mcp"] }
```

**Why neither was available this session, now fixed:**
- **nwiro** — there was *no* `.mcp.json` at all (it's gitignored and had been cleared), so nwiro was never configured project-scoped. Now created, pointing at the WSL-reachable `:5354` portproxy (socket confirmed alive).
- **ue-docs** — it's in your global `~/.claude.json`, but the `ue-rag` Docker container only came up **3 min ago**, so at *this* session's start `docker exec ue-rag` failed. It's **Up (healthy)** now.

## To activate: start a fresh Claude session

MCP tools bind only at session start, so a new session in `~/claude/projects/pair-o-dox` will attach **both nwiro and ue-docs**. After it starts, I'll confirm with a quick `get_level_info` (nwiro) and a ue-docs query before building.

**Two cautions for the new session:**
1. **Don't relaunch the UE editor between now and starting the session** if you can avoid it — the nwiro plugin rewrites `.mcp.json` to `localhost:5353` on launch, which (a) is unreachable from WSL and (b) would drop the ue-docs entry. If it does get clobbered, ue-docs still loads from your global config; only nwiro's URL would need resetting to `:5354`. (The editor's already running, so ideally just leave it.)
2. The `ue-rag` container must stay up — it's healthy now, so you're set.

## Then we crack on with M3

Fresh session = full toolkit: ue-docs to ground the UE 5.7 API, nwiro to author the editor-side assets (materials, DataAssets, test room) and drive the PIE no-leak test. I'll still produce the C++ spine source (first `Source/` module + `UPerceptionComponent` + `UPerceptionProfile`), with the first compile on the Windows host. I'll use the workflow with models that fit, as you asked.

When you're ready, restart the session and just say "continue M3" — `memory.md` has the full context. Want me to jot a one-line note in `memory.md` about the ue-docs wiring before you switch, so the next session sees it immediately?

• Read /home/megaproxy/claude/projects/pair-o-dox/memory.md 9ms 4.6 KB

Let me read memory.md's structure so I append the note in the right place and format.

• Edit /home/megaproxy/claude/projects/pair-o-dox/memory.md 19ms 160 B

Now let me update the two relevant TODO lines so they reflect the new state, then commit.

• Edit /home/megaproxy/claude/projects/pair-o-dox/memory.md 32ms 160 B

• Edit /home/megaproxy/claude/projects/pair-o-dox/memory.md 41ms 160 B

• Bash cd ~/claude/projects/pair-o-dox && git add memory.md && git commit -q -m "Log: ue-docs+nwiro wired into .mcp.json; M3 = … 3.2s 147 B

Noted and pushed. `memory.md` now has a **"START HERE"** session-log entry (committed `f4fd310`) capturing everything the next session needs:

- **First line tells it what to do:** restart Claude, then "continue M3."
- **MCP state** — both `nwiro` (`:5354`) and `ue-docs` (docker `ue-rag`) are now in `.mcp.json`; why they were missing this session; the verify-on-start checks; and the two cautions (don't relaunch the editor before restart; keep `ue-rag` up).
- **M3 plan** — the decided C++-spine approach, the file/module layout, the Windows-host compile, the nwiro editor-asset + PIE no-leak test, and the workflow/model split.

I also flipped the M3 and nwiro-reachability TODOs to reflect the decisions.

You're clear to restart. In the fresh session, just say **"continue M3"** — it'll read `memory.md`, confirm `nwiro` + `ue-docs` are live, and start building the spine.
