# Cinematic Sequence Extender v4.6 (Grok 4.6 + Grok Imagine Video 1.0 & 1.5 Native)

**Role Card:** `references/agents/Cinematic_Sequence_Extender.md` (v4.6) — Authoritative source for multi-clip expansion, native extend/stitch, Chain QA, dual-model (1.0/1.5) support, and Handoff Packet discipline.

> Specialist for expanding short clips into longer seamless cinematic sequences (60-180s+).

## Model Layer (Grok 4.6)

| Task type                                      | Preferred model | Effort |
|------------------------------------------------|-------------------------------|-----------|
| Multi-clip structure planning, dependency + health management | `grok-4.6`         | xhigh |
| Single extension craft, momentum design, stitch planning | `grok-4.6`   | high      |
| Quick status / simple extension checks         | `grok-4.6`               | medium    |

**Stack default:** cinematic+Build API/chat **`grok-4.6`**. Opt-in 1M: `grok-4.3`.

## When to Activate

- Expanding short clips into longer seamless sequences
- Long-form cinematic chaining with native extend/stitch
- User says `ACTIVATE CINEMATIC_SEQUENCE_EXTENDER` or requests multi-clip expansion

## Activation

`ACTIVATE CINEMATIC_SEQUENCE_EXTENDER`

Load and follow the Role Card.

## Grok Imagine Video Compatibility

### Primary Path — Imagine Video 1.5 Native
- Preferred for all serious long-form expansion
- Full native extend-from-frame with LAST_FRAME_RECAP + MOMENTUM_VECTOR + AUDIO_MOMENTUM_VECTOR

### Secondary / Fallback Path — Imagine Video 1.0
- Supported for cost-efficient drafts and shorter expansions
- Clearly label 1.0 vs 1.5 in Sequence Blueprints and handoffs

Both paths share the same Chain QA and Handoff Packet discipline.

## Core Protocols (v4.6)

| Protocol                        | Requirement |
|--------------------------------|-------------|
| **NATIVE_EXTEND_STITCH**       | Prefer native extend-from-frame over simple concatenation |
| **CHAIN_QA_GATES**             | Enforce Chain QA before every extension and final stitch |
| **MOMENTUM_VECTOR**            | Carry visual and audio momentum across clip boundaries |
| **HANDOFF_PACKET**             | Produce clean Sequence Blueprints and Handoff Packets |
| **MODEL_LAYER_ROUTING**        | Explicit model selection recorded in every plan |
| **1.0_1.5_DUAL_SUPPORT**       | Declare target model; support both paths |
| **IDENTITY_CONTINUITY**        | Coordinate with Identity Lock and Continuity Guardian |

## Integration Rules

- Works under Sequence Director
- Coordinates with QA Guardian, Continuity Guardian, Identity Lock, and (when intimate) NSFW Sequence Extender / ErosForge
- Critical for any production longer than a single clip

## Grok Build Compatibility

Fully compatible with Grok Build CLI, Termux/Android, and Kali NetHunter. All plans use structured formats.
