Sub-stage 6-R-0 committed (ded9603). Now per the mission's STOP rule, I report to the user and ask for direction before 6-R-1. The decision point: The verdict changes the landscape: 1. The repair (6-R-1, T = c√n proof) is still needed by the main line regardless — it's the provable route. The E-032 repair-height data strengthens the case (envelope collapses, ratio ~1). 2. But the T = √n per-side claim now looks TRUE — there might be a salvage question (new oscillation machinery), which is research-level and open-ended. The mission explicitly scoped this OUT unless the verdict said "small" — it did — so the user should decide whether to open that direction. Options for the user: (a) Proceed with 6-R-1 as planned (repaired proof at T = c√n) — the main line's repair (R) needs it; the T=√n salvage stays closed/parked. (b) Proceed with 6-R-1 AND open a side exploration of the T = √n hidden-cancellation phenomenon (research-level; e.g., understand the cancellation mechanism — it's not stationary-phase; possibly relate to the exact residue identity). (c) Pause and think. Note also: the per-side claim being empirically true is a nice addition to the finding note/letter (strengthens the "the theorem statement survives" narrative). Also — per the mission the verdict D4 paragraph will combine E-032 with the circularity analysis. That stays for 6-R-2. Let me present the results crisply and ask. Per the fork rule (8.4a), when the path forks, do all of them one by one — but the mission explicitly put a STOP here for user direction. Also the mission says D2 (repaired proof) is a deliverable regardless — the STOP is specifically "before pursuing" the T=√n salvage. Reading carefully: "the T = √n salvage as a proof goal (D1's verdict settles whether anything there remains to pursue — if |I_II| comes out SMALL, STOP and report to the user before going further)". "Going further" = pursuing the salvage. So strictly, 6-R-1 (the repair proof) is still the thread's planned next sub-stage and doesn't require new authorization — but given the verdict materially changes the picture (the per-side claim looks TRUE, which affects the letter/finding-note framing AND potentially the repair's urgency), reporting now and asking is the right call. The mission says "STOP and report to the user before going further" — I'll comply and ask. I'll use AskUserQuestion with the options.
Sub-stage **6-R-0 COMPLETE** and committed (`ded9603`). Per the mission's STOP rule, reporting the verdict before going further. ## E-032 verdict: HIDDEN CANCELLATION — decisive At T = √n (zero-avoiding), the true complex right-tail integral vs its envelope: | n | \|I_right\| | envelope | \|I\|/env | \|I_II\| (full side) | \|I_II\|/√n | |---|---|---|---|---|---| | 10³ | 7.18 | 50.8 | 0.141 | 7.44 | 0.235 | | 10⁴ | 16.70 | 1.03×10⁴ | 1.6×10⁻³ | 19.21 | 0.192 | | 10⁵ | 26.23 | 4.71×10¹⁰ | **5.6×10⁻¹⁰** | 30.89 | 0.098 | **What this settles:** 1. The per-side claim |I_II| = O(√n) is **empirically TRUE** — with a *decreasing* ratio to √n. Lagarias's Thm 6.1 conclusion looks right; only its *proof* is broken (exactly as D-072 suspected). 2. The envelope is catastrophically pessimistic — oscillation kills essentially all of the e^{0.066√n} peak (cancellation ~2×10⁹× at n=10⁵). No stepping/triangle method at T = √n can work, confirming F-D structurally. 3. The mid-part [−5/2, 3] has almost **no** cancellation (ratio 0.7–0.95) — its charged bound is honest; all hidden cancellation lives in the right tail. 4. At the repair heights (c = 1.5, 2) the envelope itself collapses (≈1.0 / ≈0.35 at n=10⁵) with ratio ≈ 1 — **the repair needs no cancellation**, the elementary stepping is honest there. Method validation: mpmath vs certified Dirichlet series agreed to 6×10⁻¹⁰; trapezoid converged to 5×10⁻⁵. All numbers in D-073 §2, db-registered. **The decision this opens** (per the mission's STOP rule):
