# Kairic Edge v1.2

Kairic Edge v1.2 is a runtime correctness release. The GGUF and all three PromptForge sidecars are unchanged.

## Fixed

- Exact 65-row n-gram verification now uses the compact authoritative computation path by default.
- The previous native IU4 M65 verifier could change a greedy target token on a reproduced low-margin case.
- Kairic startup now reports `M65 verifier=strict-compact` so the active correctness mode is auditable.
- The previous route remains available only through `KAIRIC_UNSAFE_NATIVE_M65_VERIFY=1` for controlled diagnostics.

## Validation

- Six out of six responses matched the frozen no-spec target hash exactly.
- Five warm strict-M65 runs: 22.31–22.38 seconds, mean 22.34 seconds.
- Draft acceptance: 9,255/9,280 tokens, 99.73%.
- Mean accepted draft length: 64.83 tokens.
- Approximately 5–8% slower than the unsafe native M65 route on the reproduced workload.
- Approximately 7.19× faster than speculation off on the same workload.

The frozen target output contains two known arithmetic mistakes. v1.2 intentionally preserves those tokens: speculative decoding is required to accelerate the target model, not silently change its answer.

## Release scope

The release contains only the M65 correctness change and its documentation. The separately tested Qwen MTP16 verification/adaptive controls were not promoted because the matched MTP4 production profile remained faster. Native MTP4 therefore remains the recommended production default.

## Required source release

Build tag: [`kairic-edge-qwen38-27b-v1.2`](https://github.com/ciru-ai/ROCmFPX/tree/kairic-edge-qwen38-27b-v1.2) in `ciru-ai/ROCmFPX`.

Source commit: [`205a3e5f40e5542e2f2eb68e3d3f81f918b1d895`](https://github.com/ciru-ai/ROCmFPX/commit/205a3e5f40e5542e2f2eb68e3d3f81f918b1d895).

The immutable tag exists publicly and the release source passed a clean `llama-server` build, startup/help check, and runtime dependency check on Sozo.

## Acknowledgment

Pete independently proposed the same fail-closed M65 direction in the Hugging Face discussion. We statically cross-checked that proposal against this implementation before release; v1.2 keeps the stricter explicit unsafe override and auditable startup mode.
