+# Raw KV-Cache Handoff Lab
+
+This model-companion repository defines `KVC1`, a fail-closed container for raw
+key/value cache tensor bytes, plus an explicit translation contract for moving a
+contained idea into another model family's cache geometry.
+
+KV tensors are runtime activations, not model weights. Direct reuse requires
+matching model/tokenizer identity, tensor geometry, RoPE semantics, layout, and
+sequence position. Cross-family handoff requires a trained and evaluated
+translator.
+
+The optional `DOMCAP1` sidecar pack, **Analytics Hotshot**, contains a compact expert briefing,
+trusted host-tool identifiers, a source policy, and evaluation probes. The
+portfolio fetches the JSON artifact after a visitor elects to load the pack,
+validates every requested tool against its local allowlist, and injects the
+bounded briefing into the next request. DuckDB-Wasm—not the language model—runs
+the calculation.
+
+## What this is
+
+- A reproducible raw KV-cache serialization and compatibility prototype.
+- A contract for a versioned source-to-destination translation layer.
+- A small, inspectable companion artifact for a browser-hosted base model.
+- A way to measure task improvement against byte and estimated token cost.
+
+## What this is not
+
+- It is not a fine-tuned checkpoint or a copy of the base model.
+- The current reference does not yet train a cross-family translator.
+- It does not prove that a small model inherits a larger model's intelligence.
+- It grants no credentials, arbitrary network access, SQL execution, or source-code execution.
+
+## Artifacts
+
+- `reference/kvcache.py`: KVC1 reference reader/writer and inspector.
+- `translation/bridge-contract.schema.json`: cross-family translator receipt.
+- `capability-packs/analytics-hotshot.domcap.json`: optional operating sidecar.
+
+The associated schema is `capability-packs/domcap.schema.json`. A host must
+still maintain its own trusted tool catalog; a remote container must never be
+allowed to supply executable implementations.
+
+## Base model and context accounting
+
+The current desktop base model is
+[`onnx-community/Qwen2.5-0.5B-Instruct`](https://huggingface.co/onnx-community/Qwen2.5-0.5B-Instruct).
+Its configuration advertises 32,768 maximum positions. The portfolio uses a
+separate conservative bound of 3,200 dynamic prompt characters for browser
+reliability and reports the capability pack's estimated prompt footprint.
+
+## Research status
+
+Version 0.1.0 is a working infrastructure prototype. The included probes define
+the intended behavior, but comparative base-versus-container capability scores
+have not yet been published. Until those evaluations exist, the pack's status
+remains `prototype`, not `validated`.
+
+Two later experiments are specified in the portfolio research note:
+
+1. directed conflict retention for targeted catastrophic-interference tests;
+2. anisotropic relational retrieval, inspired by view-dependent Gaussian
+   representations but not assumed to share their geometry or compression law.
