The analyzer only mapped plain-lora groups, so a file carrying no plain
lora (a pure lokr, for example) analyzed zero modules and fell through to
a 1.0 default: it reported perfect fidelity for exactly the files that
degrade most. Measured on the shipped krea 2 uint4 checkpoint, those
files land between 0.04 and 0.34.
Every targeted module is now rebuilt with the loader's own module class
and its delta read from the production calc_updown, so lokr, loha, oft,
full, ia3, glora, norm and the dora / dense-bias / diff_b variants are
measured as they apply; factor-path eligibility is decided by calling the
loader's own predicate. Modules carrying several families sum their
deltas the way the loader stacks them, and a family the tool cannot
rebuild is reported instead of counting as clean.
- report per-module applied fidelity (1.0 on the factor path, measured
rho on the requantize path) as a median and an energy-weighted mean
- add --dtype bf16 to measure the unquantized reference rather than
assert it
- drop the per-module empty_cache: it cost 16ms per module against 1ms
of reuse, and the caching allocator already reuses the buffers
- keep shard handles open across modules
