PLN corrected two rows: he played rose_rouge and livecode_parade, not blue_gold.
The fusion now reaches both WITHOUT being told, which is the whole point.

29:57 crossmatch said blue_gold at a weak 0.44 margin; tempo measured 118.1
against blue_gold's declared 124 — a clash — and rose_rouge is declared 118,
with locate holding `rose` at 0.602 offset consistency. Two lenses override one.
54:59 the same shape: measured 130.0, gimme_acid declares 80, livecode_parade
declares 130, locate had `love_parade` at 0.399.

Both were only reachable because crossmatch STRUCTURALLY cannot name them.
rose_rouge played neither reference gig, and livecode_parade's .tidal was created
in the CosmicFest prep commit itself, so no prior render of it can exist anywhere.
A blind spot, not a tuning failure — and the fix is one render per new track.

The tempo lens took three attempts, and the first two measured nothing.
librosa.feature.tempo returned 107-130 for every segment of an 80-170 BPM set:
that is its log-normal prior centred on 120, not the music. Mode of inter-onset
intervals on the full mix returned 233-648 BPM, locking onto the hats rather than
the beat — and its apparent matches were hollow, because five octave multiples at
5% tolerance passes roughly a quarter of random values. Autocorrelation of the
40-120 Hz kick band works: bombe 123.9/124, punkachien 170.1/170, vague_de_crime
120.1/120, do_it_right 178.3/2 = 89.15/89. Four exact to 0.1%.

That validation is what licenses the overrides. An instrument which agrees where
it should is one whose disagreements carry information; without those four hits I
would be overriding a strong embedding on the word of an estimator I had not
checked (feedback_check_the_instrument_first).

I also had to fix my own fusion: counting each top-3 tempo candidate as a vote let
cafe_bouillant beat ouais_je_funk, which measured 120.1 against a declared 120 —
a perfect match demoted by an alphabetical tie. Tempo compatibility CONFIRMS the
embedding's proposal; it only overrides when it clashes AND a second lens agrees
on a specific alternative.

Four rows are now marked unresolved rather than confidently labelled. That is a
real answer: a confident wrong row costs more than a blank one.
