No return recorded after #2308 — on route 128 or on a linked\nroute — answers it. The step is copied **exactly** as the replacement `next_step`.\n\n## Step identity\n\n- Route 128 `state=active`, `revision=16`, `last_return_id=2308`, `updated_at=2026-10-05T09:53:32.995Z`.\n- The canonical sorted-key JSON sha256 of `route128.next_step` is\n  `c676d076c12dcdbc86a1e829b293663336ef5b8541d16515808774f956c6d5fc`. It is simultaneously the served\n  `next_step`, **#2308**'s `research.next_step` (the setter), and the step parsed from this brief.\n  Older steps `50ff826e…` (#2181, carried by the step checks #2293/#2304) and `7ab3a088…` (#2072,\n  carried by #2177) are different and superseded.\n\n## The route has moved nowhere since the setter\n\nThe route's event list begins `1089 #2308, 1085 #2304, 1078 #2293, 992 #2181, …`. The maximum\n`return_id` over all events is **2308**; there is no route-128 event after the setter. #2308 itself\nends with *\"A distinct experiment: classify each of the 12 drift cells as cut-reverted revision vs\nordinary later edit (the route's central uncertainty). Budget 1 h, cpu 0.\"* — the setter declares the\nstep explicitly open.\n\n## The one return offered for comparison does not answer it\n\n**#2361** (route **36**, `progress`, recorded 2026-10-05T23:46:09Z) postdates #2308, but it is a\nroute-36 pursuit on the `3^{ν(q)}` weight absorption / weighted large sieve. It carries **zero** of\nroute 128's answer tokens (`mirror`, `QUESTIONS.md`, `a3e07372`, `drift`, `changed-cell`, `reverted`,\n`restore-83-153`, `cda1e669`, `corner-correlation`, `centered-discrepancy`, `global-factor`,\n`q-at43-bigint`, `served v10`, `pre-cut`, `later edit`, `gen_more`, `check_j`, `fresh_C`, `fresh A/B`,\n`re-apply`). Its `research_route_id` is 36; its own step is a *weighted large-sieve inequality*, sha\n`9832143e…` ≠ `c676d076…`; its citations are route 36's own returns `{2243, 2357, 2163}`. It names\n#2308 only inside its own issued brief, as a **comparison return** it scored (there, #2308 carries\nzero of *route 36's* tokens). The relationship is one-way: #2361 does not classify route 128's drift\ncells.\n\n## Decision\n\n`promising`, with the served step copied verbatim.\n\n- Not `known`: no recorded return classifies any of the 12 drift cells.\n- Not `progress`: no comparison return answers **any** part of the classification, and an\n  unchanged-step comparison on another route is not new evidence. #2308's execution already closed\n  legs (a)–(d); the *classification* leg is exactly what remains.\n\n## Scope\n\nNo experiment was run and no computation reproduced (`cpu_hours = 0`). Nothing here changes any\nroute's mathematical conclusion — route 128 is a record-integrity route. Its retained pending\npremise #1828 (`pending`) keeps the classification conditional.
