## Core instruments
- **ΔS (delta-S)** — *Semantic stress.* `ΔS = 1 cos(I, G)` where `I` is item embedding, `G` is ground/anchor.
Thresholds: `<0.40` stable · `0.400.60` transitional · `≥0.60` high risk.
- **λ_observe** — *Layered observability state.*
Symbols: `→` convergent · `←` divergent · `<>` recursive · `×` chaotic.
- **E_resonance** — *Coherence indicator.* Rolling mean of |residual| under BBMC; rising E with high ΔS ⇒ apply BBCR/BBAM.
---
## Repair operators (WFGY modules)
- **BBMC** — *Boundary-Bounded Memory Chunks.* Reduce semantic residue vs anchors; align chunks/sections with tasks.
- **BBPF** — *Branch-Bounded Prompt Frames.* Explore multiple semantic paths safely; stabilize context windows.
- **BBCR** — *Break-Before-Crash Reset.* Detect collapse, insert bridge node, restart cleanly.
- **BBAM** — *Attention Modulation.* Reduce variance in attention to avoid entropy melt on long contexts.
---
## Retrieval, ranking & prompting
- **RRF (Reciprocal Rank Fusion)** — Fuse ranks from multiple retrievers via `1/(k + rank)`.
- **MMR (Maximal Marginal Relevance)** — Diversify candidates balancing relevance and novelty.
- **BM25** — Sparse lexical scoring for exact term match; strong for code/IDs.
- **HyDE** — Hypothetical document expansion; creates a synthetic query/doc to improve recall.
- **Cross-encoder reranker** — Jointly encodes `[query ⊕ doc]` for precision@k gains.
---
## Patterns (named failure modes)
- **SCU (Symbolic Constraint Unlock)** — Model merges sources or violates “cite-then-explain” schema. Fix: per-source fences + locked schema.
- **Query Parsing Split** — Dense and sparse retrievers use different analyzers/tokenizers; hybrid breaks.
- **Vectorstore Fragmentation** — Index contains “ghost” gaps; facts exist but never retrieved; fix shard/id audits.
- **Memory Desync** — State flips between sessions/tabs; require `mem_rev`+`mem_hash`.
- **Role Drift** — Multi-agent persona swap; tag agent IDs and lock via BBCR.
---
## Multi-agent
- **Agent boundary** — Contract that limits what an agent can read/write; prevents overwrite.
- **ΔS peer check** — Measures divergence between agents plans to catch conflicts early.
---
## Data & ops
- **Gold set** — Small set (1050) of realistic Q/A with citations; used for CI (recall@50, nDCG@10, ΔS).
- **Traceability** — Provenance from answer → prompt → citations → chunks → source file.
---
## Notation quickies
- `I` — item (retrieved chunk) embedding; `G` — ground/anchor embedding.
- `‖B‖ ≥ B_c` — collapse threshold on residual magnitude (BBCR).
- *Convergent λ* — layer is stable across paraphrases; *divergent λ* — layer is drifting.
