# MTL Builder Operations
## Wittgenstein's Language Game Applied to LOGOS

Wittgenstein's "builder's language" (from Philosophical Investigations §2) consists of:
- **Slab!** (request object)
- **Block!** (request object)  
- **Beam!** (request object)
- **Column!** (request object)

The builder calls, the assistant brings. This is **pure action through naming**.

## MTL Mapping

| Builder Language | MTL Operation | Effect |
|:-----------------|:--------------|:-------|
| "Slab!" | `(hold 'slab [6])` | Store value 6 under 'slab |
| "Block!" | `(grab 'slab)` | Retrieve stored value |
| "Beam those!" | `(connect [A] [B])` | Combine A × B |
| "That slab!" | `(route [6] [42])` | Move value to domain |

---

## HOLD - The Register

```lisp
(hold 'x [6])    ; Store 6 as 'x
(hold 'y [7])    ; Store 7 as 'y
```

HOLD creates a **named register**. The value persists in `memory`.

---

## GRAB - The Retrieval

```lisp
(grab 'x)        ; Returns 6
```

GRAB retrieves from the register. In builder terms: "Give me that slab!"

---

## CASCADE Operations

### Example 1: Store then Retrieve
```lisp
(hold 'a [2])           ; a = 2
(hold 'b [3])           ; b = 3
(mult (grab 'a) (grab 'b))  ; 2 × 3 = 6
```

### Example 2: Chain Connections
```lisp
(hold 'image [17])
(hold 'text [19])
(hold 'relation (connect (grab 'image) (grab 'text)))
; relation = 17 × 19 = 323
```

### Example 3: Builder Workflow
```lisp
; "Hold the slab, hold the beam, connect them"
(hold 'slab [5])
(hold 'beam [7])
(hold 'structure (mult (grab 'slab) (grab 'beam)))
; structure = 35

; "Now persist the structure"
(mult (grab 'structure) [7])  ; 35 × 7 = 245 (with PERSIST flag)
```

---

## Domain Operations

HOLD/GRAB work within the **active domain**:

```lisp
(domain [1700])              ; Enter VISUAL domain
(hold 'frame [17])           ; Store in VISUAL context
(domain [1900])              ; Switch to TEXT domain  
(hold 'word [19])            ; Store in TEXT context
```

---

## The Builder Axiom

> **Calling a value IS moving it.**

In Wittgenstein's game, "Slab!" doesn't describe a slab—it **commands one to appear**.  
In MTL, `(grab 'x)` doesn't describe x—it **retrieves x to the current context**.

The act of naming is the act of manifesting.

## Cascade Patterns

| Pattern | Operations | Result |
|:--------|:-----------|:-------|
| Store-Compute-Store | hold→op→hold | Accumulator |
| Gather-Combine | grab,grab→connect | Composition |
| Build-Persist | hold→mult [7] | Permanent record |
| Route-Chain | route→route | Pipeline |
