Three real faults found by adversarial review of 299941a:
- sample()'s own default for h3_q_steer_block was "0,1" while INPUT_TYPES
declared "" -- any saved workflow predating this widget omits the key
entirely, so ComfyUI falls back to sample()'s default, silently turning on
capture/clone/hook for every H3 generation with a refinement key. Now both
default to blank, matching every sibling knob in this file.
- The "applying learned direction(s)" console line fired whenever a direction
was available, not when it was actually applied -- strength=0 still printed
it, which is the exact silent-success-message trap this project has already
been burned by. Now split into an "applying" line (strength>0) and a
"capturing only" line (strength=0).
- A direction banked under a different heads*head_dim layout (model swap on
the same refinement_key) hit an unguarded .view() and would hard-crash
generation instead of degrading. Now checked and skipped with a one-time
notice, same pattern as the existing batch>1 guard.
Added regression tests for all three, plus two coverage-gap tests the review
flagged (kind isolation against REAL persistence, not mocks; two named blocks
steering with independent directions in one run).
