SirStone 669f9acd41 docs(research): assess TM-DEB paper against the Tsetlin gun's real failure
Verdict: the document (docs/papers/tm-deb-paper.pdf, 'Generated by
Gemini Notebook') solves temporal credit assignment under delayed
reward, which is not our problem. Our gun's failure is clause
saturation (~131 of 1740 literals included per clause -> conjunction
fires with probability ~2^-131 -> correction identically 0), and
TM-DEB only scales update FREQUENCY by gamma^dt, so it would leave
the fixed point untouched and additionally delete the long-range
feedback we need: gamma^90 = 4.4e-7 at the paper's own gamma=0.85,
and those are the shots whose lead matters most.

Credibility signals recorded in the doc: reference [2] misattributes
authors/venue/year; Algorithm Spec 2 steps 9-12 are literal '%'
placeholders so the automata update is simply absent; Table 1 is
titled 'Expected' and reports never-measured accuracies; Eq. 12 is
not a faithful copy of Granmo's Lemma 2.

The audit also produced the actionable result: a line-by-line diff of
Granmo Table 2/3 feedback against tmLearnOne, identifying why the
automata saturate - Type I never conditions on the clause output so it
omits Granmo's c=0, lk=1 -> -1 w.p. 1/s counter-force (true literals
ratchet toward Include), Type II's guard cOut==1 AND lits[lit]==0 is
unsatisfiable and therefore dead code, and the (T - clip(v,-T,T))/(2T)
resource allocation is missing entirely.
