KV-COBRA calibrates a per-head SVD, jointly enumerates rank and integer bit width in C1, performs five damped C2 redistribution rounds, optionally reorders directions by query–key variance product for the KL variant, and fuses the Hadamard rotation into the stored basis; inference then uses the frozen per-head choices.

The complete result group stays with its claim. Assessed rows come first; their judgments do not replace the whole-claim conclusion. Expand a row for conditions, sources, and evidence history.

Each row is a measurement with its reported value, latest available observation, and cumulative evidence state.
