# Multimodal & Long-Context — Global Fix Map

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.

## Common failure patterns

| Page | Symptom (what you see) | Likely root cause | Fix route |
|------|------------------------|------------------|-----------|
| [alignment-drift.md](./alignment-drift.md) | Text and image pairs gradually diverge across long windows | Context length weakens positional anchors | Re-anchor at checkpoints, enforce ΔS probe |
| [anchor-misalignment.md](./anchor-misalignment.md) | Citations point to wrong caption/image | Inconsistent `anchor_id` across modalities | Add schema guardrail to enforce anchor IDs |
| [boundary-fade.md](./boundary-fade.md) | Signals near context edge disappear | Context window cutoff, padding ignored | Boundary probes, chunk anchors at joins |
| [caption-collapse.md](./caption-collapse.md) | Captions vanish or repeat when context grows | Fusion loses reference alignment | Use caption schema, enforce cite-first |
| [cross-modal-bootstrap.md](./cross-modal-bootstrap.md) | Model never uses one modality | Missing initialization anchors | Add bootstrap token + schema lock |
| [cross-modal-trace.md](./cross-modal-trace.md) | Hard to verify which modality answer came from | No traceability field | Require `modality_id` and `source_url` in snippet |
| [desync-amplification.md](./desync-amplification.md) | Small anchor misalignments grow into collapse | Weak λ convergence across modalities | Run multi-seed probes, lock λ variance |
| [desync-anchor.md](./desync-anchor.md) | Anchors for vision vs text drift apart silently | Schema mismatch at join | Enforce alignment with ΔS ≤ 0.50 |
| [echo-loop.md](./echo-loop.md) | Answer repeats cross-modality content | Fusion loopback between modalities | Add dedupe guardrail, enforce λ drop |
| [fusion-blindspot.md](./fusion-blindspot.md) | One modality is ignored entirely | Fusion weights collapse | Hybrid retriever weighting, enforce balance |
| [fusion-latency.md](./fusion-latency.md) | Delay in syncing vision vs text streams | Async fusion queue | Add latency probe, resync alignment |
| [modal-bridge-failure.md](./modal-bridge-failure.md) | Text → Image reasoning chain breaks mid-hop | Bridge tokens dropped | Schema lock for bridge anchors |
| [modality-dropout.md](./modality-dropout.md) | Whole modality disappears mid-sequence | Token truncation or stream loss | Re-chunk, enforce modality coverage |
| [modality-swap.md](./modality-swap.md) | Image and text roles flip silently | Anchor IDs reused wrongly | Explicit `modality_role` field required |
| [multi-hop-collapse.md](./multi-hop-collapse.md) | Multi-hop reasoning stops using one modality | Missing cross-hop anchors | Add cross-hop continuity guardrail |
| [multi-seed-consistency.md](./multi-seed-consistency.md) | Different seeds give different modalities | λ non-convergent | Probe across seeds, enforce stability |
| [multimodal-fusion-break.md](./multimodal-fusion-break.md) | Fusion fails when 3+ modalities | Overload in join schema | Use staged fusion, test ΔS at each join |
| [phantom-visuals.md](./phantom-visuals.md) | Model hallucinates new images | Weak anchor trace | Enforce trace schema, drop hallucinated spans |
| [reference-bleed.md](./reference-bleed.md) | Answer pulls from wrong modality reference | No modality fence | Add fence keys (`modality_id`) |
| [semantic-anchor-shift.md](./semantic-anchor-shift.md) | Anchors shift mid-context | Anchor ID reused | Audit schema, reset anchor IDs |
| [signal-drop.md](./signal-drop.md) | Structured data missing mid-run | Serialization loss | Add schema field for `signal_id` |
| [spatial-fusion-error.md](./spatial-fusion-error.md) | Wrong layout in multimodal outputs | Spatial anchors lost | Enforce bounding-box schema |
| [sync-loop.md](./sync-loop.md) | Model stuck repeating stale multimodal state | Old anchors not cleared | Add state reset guardrail |
| [time-sync-failure.md](./time-sync-failure.md) | Audio/text/video out of sync | Missing time index alignment | Require `time_index` schema |
| [visual-anchor-shift.md](./visual-anchor-shift.md) | Visual anchors move between runs | Vision embeddings unstable | Lock anchor IDs + ΔS probes |

## 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.
