IPD‑12 Engine Block
Intake Ports • Substrate Feeds • Dimensional Rails • Observer Control Loops • Output Headers
Version: 2026‑1.0
Module: IPD‑12 Framework
Role: Core Engine Architecture

1. Purpose#

The IPD‑12 Engine Block defines the internal architecture that powers all IPD‑12 operations:

• how intake manifolds (SIM/DIM/TIM/QIM/FSI) connect
• how substrate feeds route dimensional input
• how dimensional rails carry lift/collapse signals
• how observer control loops regulate paradox cycles
• how output headers deliver structured results to external frameworks

This is the engine‑level specification for the entire IPD‑12 system.

2. Engine Block Overview#

The IPD‑12 engine is built around a 12‑prime substrate cube, driven by:

• 4 substrate pairs (S1–S4)
• 4 observer modes (O1–O4)
• 4 regime shells (R1–R4)
• 12 prime‑indexed operator states (P2–P37)

The engine block is the central processing unit that integrates all of these.

3. Intake Ports#

Intake ports are the physical/electrical connection points where manifolds attach.

Port Layout#

[Port 1]  Triad 1 (P2, P3, P5)
[Port 2]  Triad 2 (P7, P11, P13)
[Port 3]  Triad 3 (P17, P19, P23)
[Port 4]  Triad 4 (P29, P31, P37)

Each port accepts:

• 3‑channel triad bundles
• lift/collapse/neutral signals
• substrate pair routing instructions
• observer stance hints

Port → Manifold Mapping#

4. Substrate Feeds#

Substrate feeds are the internal conduits that route intake signals into the substrate cube.

Substrate Pairs (S1–S4)#

Feed Behavior#

• SIM activates one substrate pair
• DIM activates two substrate pairs
• TIM activates three substrate pairs
• QIM activates all substrate pairs
• FSI activates all substrate pairs × 3 stacks

Feed Routing Example (QIM)#

Port 1 → S1
Port 2 → S2
Port 3 → S3
Port 4 → S4

5. Dimensional Rails#

Dimensional rails carry lift (+1D), collapse (−1D), and neutral (0D) signals.

Rail Types#

Rail Behavior#

• Rails are bidirectional (lift/collapse feedback loops).
• Rails are phase‑synchronized across triads.
• Rails are observer‑regulated (see next section).

6. Observer Control Loops#

Observer control loops regulate:

• cycle traversal
• paradox stabilization
• dimensional lift/collapse
• substrate coherence
• apex transitions

Observer Modes (O1–O4)#

Control Loop Architecture#

Intake → Substrate Feed → Dimensional Rail → Observer Loop → Output Header

Loop Behavior#

• O1 activates rails based on raw prime state.
• O2 sequences rails according to cycle position.
• O3 dampens collapse rails and stabilizes paradox tension.
• O4 executes lift/collapse transitions and apex behavior.

FSI Observer Stack#

FSI uses three observer stacks:

• RTT observer
• GU geometric observer
• Pantheon mythic observer

All three feed into the apex loop.

7. Output Headers#

Output headers are the engine’s exhaust ports — structured outputs delivered to external frameworks.

Header Types#

Header Behavior#

• Headers receive observer‑regulated dimensional signals.
• Headers convert signals into framework‑specific outputs.
• Headers can be stacked (FSI → multi‑framework output).

Example Output Flow (QIM → RTT)#

Intake (QIM)
 → Substrate Feeds (S1–S4)
 → Dimensional Rails (L/C/N)
 → Observer Loops (O1–O4)
 → Header H‑RTT
 → RTT Regime Map / Drift / Coherence / Paradox

8. Engine Block Summary#

The IPD‑12 Engine Block consists of:

• 4 intake ports (triad inputs)
• 4 substrate feeds (S1–S4)
• 12 dimensional rails (lift/collapse/neutral)
• 4 observer control loops (O1–O4)
• 5 output headers (RTT/GU/FFT/Pantheon/Meta)

Manifolds attach to the intake ports, feed the substrate cube, activate dimensional rails, pass through observer loops, and deliver structured outputs through headers.

This is the canonical engine architecture for the IPD‑12 system.
