Multimodal and long context scenarios:
long document with images and tables loses alignment later
figure caption no longer matches chart after many turns
audio plus transcript plus slides get out of sync over time
user asks about a specific figure but answer cites wrong one
first runs use both text and images later runs use text only
adding third modality breaks earlier working setup
structured signals such as metrics or events disappear mid chain
same question sometimes answered from image sometimes from text
hallucinated diagram appears in reasoning but not in source
vision or audio encoder version changed but logs do not show
anchor_id reused across different images in one session
Signals to check:
delta s low on local snippet high on cross modality join
lambda unstable when mixing modalities even if single is stable
coverage good for text but low for visual anchors
missing modality_id or source_url in retrieved snippets
anchor_id or snippet_id missing or reused across items
time_index gaps between audio and text segments
bbox or spatial anchors missing in visual snippets
different seeds pick different modalities for same question
fusion layer ignores one modality on long windows only
trace logs do not show which modality drove the final answer
Normalization and contracts:
require snippet_id modality_id anchor_id section_id for all snippets
log time_index for audio and video aligned with transcript
enforce unique anchor_id within each session
record source_url or asset_id for every visual reference
lock encoder versions for text vision audio in data contracts
store per modality coverage and delta s in logs
document fusion strategy and weights in retrieval playbook
tie multimodal updates to explicit checkpoints not every token

A friendly hub to keep **text, vision, audio, and structured signals** stable inside **long context windows**.
Use this folder when models collapse, drift, or desync under multimodal fusion or cross-sequence reasoning.
---
## What this page is
- A compact map of **failure patterns unique to multimodal + long-context**.
- Each page gives you **symptoms → root cause → WFGY guardrails**.
- Works with **schema-level fixes only** (no infra changes required).
- Every fix is **measurable and reproducible** using ΔS, λ, and E_resonance.
---
## When to use
- Text and vision anchors misalign beyond 50k–100k tokens.
- Captions collapse or disappear when windows grow.
- Visual snippets appear but point to the wrong text.
- Multi-hop reasoning flips answers across modalities.
- Cross-sequence fusion drops or swaps semantic anchors.

## Acceptance targets
- ΔS(question, retrieved) ≤ 0.45
- ΔS across modality joins ≤ 0.50
- Coverage ≥ 0.70 for intended anchors
- λ convergent across 3 paraphrases and 2 modality-seeds
- E_resonance stable across text–vision–audio triads
---
## Fix in 60 seconds
1. **Pick one failing case**
(e.g. caption does not match paragraph). Keep a reference screenshot.
2. **Measure ΔS and λ**
Run 3 paraphrases × 2 modality seeds. Look for flips.
3. **Check anchors**
Verify `snippet_id`, `modality_id`, `section_id` across text–vision.
4. **Patch minimally**
Re-align anchors, enforce schema, drop hallucinated spans, re-run with guardrails.
