chain-qa-protocol

name	chain-qa-protocol
description	Extend and stitch chain QA protocol for Grok Imagine Video 1.5 sequences. Runs the weighted 10-point gate before approving clips for extension or final stitch. Activate with RUN CHAIN QA REVIEW alongside Sequence Director and Cinematic Sequence Extender. Uses Grok 4.5 orchestration.

Chain QA Protocol v3.7.1 (Grok 4.5 · Extend/Stitch Gate)

Pipeline skill — boundary continuity gate for multi-clip sequences. Complements QA Guardian’s per-clip 16-point review; does not replace it.

Checklist: .grok/skills/cinematic-sequence-extender/references/chain_qa_checklist.md
Implementation: tools/sequence_chain.py (CHAIN_QA_CHECKS, run_chain_qa)
Assist: tools/chain_qa_assist.py · CLI sequence qa / sequence qa-assist
NSFW variant: nsfw-chain-qa-protocol (8-point artifact-aware)

Model Layer (Grok 4.5 · studio v3.7.1)

Layer	Slug	When
Orchestration (default)	grok-4.5	10-point chain gates, go/no-go before extend/stitch
Long-context (opt-in)	grok-4.3	Very long multi-act health reviews only
Grok Build CLI	grok-4.5 · grok-build	Skills / coding (≥ 0.2.93)
Imagine Video	grok-imagine-video / 1.5	1.0 cost · 1.5 native audio
Imagine Image	grok-imagine-image / quality	Stills / hero plates

Prefer stable prompt_cache_key (project slug). Reasoning high for go/no-go and regen vs conditional-fix. Opt into grok-4.3 only for 1M. Full stack: references/agents/MODEL_LAYER_v3.7.1.md · tools/models.py · models verify.

When to Activate

• Before every extend-from-last-frame generation
• Before final stitch of a multi-clip sequence
• After Continuity Guardian flags boundary risk
• After I2V / sequence run when clip is a chain link
• User says: RUN CHAIN QA REVIEW, CHAIN QA, SCORE STITCH BOUNDARY

ACTIVATE ONLY Sequence Director, Cinematic Sequence Extender, Continuity Guardian, Quality Assurance Guardian
RUN CHAIN QA REVIEW

Per-clip artistic/tech quality	Quality Assurance Guardian (16-point)
Intimate / explicit chains	nsfw-chain-qa-protocol

10-Point Checks (score 1–10 each)

Weights from CHAIN_QA_CHECKS in tools/sequence_chain.py:

Key	Focus	Weight
last_frame_continuity	N+1 starts from N end state	1.5 critical
momentum_carryover	Action, camera, emotion	1.2
audio_momentum_sync	Dialogue, SFX, music	1.3 critical

transition_readiness	Clean ending for extend	1.2 critical
stitch_artifact_risk	Flicker, morph, halo	1.3

Pass rules

Result	Criteria
Go	Weighted score ≥ 7.0 and no critical check < 7.0
Conditional Go	Weighted 5.5–6.9 (or fixable non-critical gaps) — fix handoff before final stitch
No-Go	Weighted < 5.5 or any critical check < 7.0 — regenerate; do not extend

Critical set: last_frame_continuity, audio_momentum_sync, character_drift_boundary, transition_readiness.

Identity Continuity (ICP-06)

When scoring character_drift_boundary / identity criteria, require handoff drift_evidence (or clip identity_drift).
If missing → finding: run ICP-02/03 (sequence drift-score).
Protocol: references/agents/IDENTITY_CONTINUITY_PROTOCOL_v3.8.md · [IDENTITY_CONTINUITY_PROTOCOL: v1.0]

Prerequisites (handoff)

Clip / packet should include:

• last_frame_recap
• momentum_vector (action, camera, emotion)
• audio_momentum_vector
• reference_image_id (when used)
• continuity_state

Decision Matrix

Result	Next step
Go	Approve extend / stitch; update sequence chain_qa_status
Conditional Go	Fix LAST_FRAME_RECAP / momentum / audio fields; re-score before final stitch
No-Go	Regenerate clip N; block extend; regen plan from chain QA + drift/seam/memory
