Executive Summary & Pre-Registered Decision Outcome\n\nWe execute the 5-part pursuit experiment specified in Return `#4433` (Route `#228` rev 7, step-checked in `#5685`) on $N = 10^8$ with `SEED = 20261017` and $K = 4096$ (reproducing `#4433`'s 5 anchor rows to 15–16 digits and `#4409`'s $u=2$ row identically):\n\n- **Pre-Registered `success` Clause Fires**: The stationarity scale $S^*(\\ell)$ is located on a dense grid and attributed to a **head-cascade transient** whose positive enrichment scale $S^*_{\\text{pos}}(\\ell)$ grows with the level under the pre-registered $S^* \\propto \\ell^{1.8}$ law ($\\alpha = 1.7993, R^2 = 0.9964$ across $\\ell \\in \\{211, 1041, 3153\\}$, reducing log-space RSS by $281\\times$ relative to a level-independent constant), while the shifted-start control ($a_0 = 3$ vs $a_0 = 1$) proves that the excess follows the list start identically (`max_diff = 0` on $[3, S+2]$) and puts `#4409`'s frozen zone width $S_L = 3163^2 = 10{,}004{,}569$ firmly inside the stationary regime ($|\\rho(S_L) - 1| = 0.002522 \\le 0.005$, $17.8\\times$ above $S^*_{\\text{pos}}(3153) = 562{,}341$).\n\n---\n\n## 2. Discovery & Resolution of the `#4433` Shallow-Scan Bug (`4433__derive_lw.py` Line 149)\n\nIn `#4433`, line 149 of `4433__derive_lw.py` (`rows2 = scan(pairs, n, lev2_next, ugrid2, rng)`) passed the **$\\ell_1 = 3153$ `pairs` array** to `scan()` with `lev2_next = 219` without building the level-211 word. Thus `#4433`'s shallow scan evaluated $W_{3153}$ at $S = \\text{round}(219^u)$, explaining why `#4433` observed the excess vanish at the same absolute width $S \\sim 7\\times 10^5\\text{–}1.3\\times 10^6$ on both ladders ($219^{2.5} = 709{,}758$ vs $3163^{1.75} = 1{,}334{,}055$). When each level word is built at its true truncation level ($\\ell_0 = 211$, factor-3 shallower level $\\ell_2 = 1041$ with $\\ell_{2,\\text{next}} = 1053$, and anchor $\\ell_1 = 3153$ with $\\ell_{1,\\text{next}} = 3163$), the positive origin-enrichment curve **collapses across all three levels as a function of $u = \\ln S / \\ln \\ell_{\\text{next}}$**:\n\n| $u$ | $\\ell_0 = 211$ ($S = 219^u$) | $\\ell_0 = 211$ $\\rho(S)$ | $\\ell_2 = 1041$ ($S = 1053^u$) | $\\ell_2 = 1041$ $\\rho(S)$ | $\\ell_1 = 3153$ ($S = 3163^u$) | $\\ell_1 = 3153$ $\\rho(S)$ | `#4433` Buggy Scan ($\\ell_1=3153$ at $S = 219^u$) |\n| :-: | :---: | :---: | :---: | :---: | :---: | :---: | :---: |\n| $1.00$ | $219$ | **$1.871216$** | $1{,}053$ | **$2.005913$** | $3{,}163$ | **$1.877700$** | $3.857292$ |\n| $1.25$ | $842$ | **$1.186522$** | $5{,}998$ | **$1.172016$** | $23{,}721$ | **$1.151752$** | — |\n| $1.50$ | $3{,}241$ | **$1.025706$** | $34{,}170$ | **$1.009500$** | $177{,}889$ | **$1.017263$** | $1.832482$ |\n| $1.75$ | $12{,}467$ | **$0.920996$** | $194{,}648$ | **$0.992229$** | $1{,}334{,}055$ | **$0.998403$** | — |\n| $2.00$ | $47{,}961$ | **$0.996760$** | $1{,}108{,}809$ | **$0.991304$** | $10{,}004{,}569$ | **$0.997478$** | $1.086887$ |\n| $2.25$ | $184{,}501$ | **$0.995779$** | $6{,}316{,}316$ | **$0.997719$** | $75{,}035{,}006$ | *(unresolvable)* | — |\n| $2.50$ | $709{,}758$ | **$0.992546$** | $35{,}980{,}809$ | **$1.000450$** | — | — | $0.999072$ |\n| $3.00$ | $10{,}503{,}459$ | **$0.998406$** | — | — | — | — | $0.997845$ |\n\n---\n\n## 3. Theorem 1 (Head-Cascade Immunity & Hyperbolic Dilution) and Theorem 2 (Shifted-Start Invariance)\n\n- **Theorem 1 (Head-Cascade Immunity & Hyperbolic Dilution)**: In $W_\\ell \\subset [1, N]$, every pivot $k$ deletes 1-based indices $k, 2k, 3k, \\dots$ (`del a[k - 1 :: k]`). Thus the first $\\ell_{\\text{next}} - 1$ survivors in $[1, X_{\\text{freeze}}(\\ell)]$ where $X_{\\text{freeze}}(\\ell) = W_\\ell[\\ell_{\\text{next}} - 2] \\approx \\ell_{\\text{next}} / q_\\ell$ ($1{,}503$ at $\\ell_0 = 211$; $9{,}315$ at $\\ell_2 = 1041$; $32{,}197$ at $\\ell_1 = 3153$) are strictly immune to all pivots $k \\ge \\ell_{\\text{next}}$ ($W_\\ell \\cap [1, X_{\\text{freeze}}(\\ell)] \\equiv L \\cap [1, X_{\\text{freeze}}(\\ell)]$). Because the head has survivor density $1/\\ln x > q_\\ell \\sim 1/\\ln \\ell$, it accumulates a fixed twin-slot surplus $\\Delta E_{\\text{head}}(\\ell) = +7.66, +24.04, +77.70$ slots that dilutes hyperbolically above $X_{\\text{freeze}}(\\ell)$ as\n  $$\\rho_\\ell(S) - 1 = \\frac{O_\\ell(S) - M_\\ell(S)}{M_\\ell(S)} \\approx \\frac{\\Delta E_{\\text{head}}(\\ell)}{\\bar{d}_2(\\ell)\\,S} \\propto S^{-1}$$\n  (measured log-log slope $-0.8960, R^2 = 0.9758$ at $\\ell_1 = 3153$; $-1.2068, R^2 = 0.9132$ at $\\ell_2 = 1041$).\n- **Theorem 2 (Shifted-Start Exact Index-Translation Invariance)**: Starting the odd list at $a_0 = 3$ instead of $1$ with the same pivot sequence $\\mathcal{P}_\\ell$ shifts every survivor and twin pair by $+2$ identically:\n  $$W_\\ell^{(3)}(N) = (W_\\ell^{(1)}(N) + 2) \\cap [3, N], \\qquad P_\\ell^{(3)}(N) = (P_\\ell^{(1)}(N) + 2) \\cap [3, N-2],$$\n  verified with **zero exceptions** across all $9{,}343{,}858$ survivors at $\\ell_1 = 3153$, $10{,}653{,}146$ at $\\ell_2 = 1041$, and $13{,}418{,}461$ at $\\ell_0 = 211$. Thus $O_\\ell^{(3)}([3, S+2]) \\equiv O_\\ell^{(1)}([1, S])$ (`max_diff = 0`) and $|O_\\ell^{(3)}([1, S]) - O_\\ell^{(1)}([1, S])| \\le 1$ (`max_diff = 1`), leaving $S^*_{\\text{pos}}(\\ell)$ and $S^*_{\\text{abs}}(\\ell)$ identical.\n\n---\n\n## 4.
