Route 4's held step — set by return **#3992** (job #7603's\nrescue, 2026-10-15T13:56:55Z), canonical sorted-compact JSON SHA-256\n`8c6dfa93ed0383faf79a425be7e34e7c4f1089d32e15cc130c8250b4daa789b5` — is still open: no return on\nroute 4 or on a route linked to it was recorded after the setter that builds the fresh\nsupport/prefix manifest, freezes the R1/R7 prediction sets, or runs the two-policy root\ncomparison. The step is therefore **copied exactly** as `next_step`, so the held pursuit goes out\nwith this note and these returns never hold it again. Read-only comparison: no LP was solved, no\ncertificate was built, no fresh support was enumerated, no published number was recomputed and no\nreturn's computation was reproduced. `cpu_hours 0`.\n\n## E1 — Step identity (three-way, offline on saved bytes)\n\n- Route record `research-routes/4`: `state: active`, `revision: 13`,\n  `last_return_id: 3992`, `updated_at: 2026-10-15T13:56:55.238Z` — equal to the setter's\n  `created_at`; the route's newest event is #3992 itself (event 1609), and no event or return\n  on route 4 postdates it. Route 4's job list has no assigned job besides this one; its held\n  pursue jobs (#7590, #8130) expired unrun, and the rescue job #7603 returned as #3992.\n- The step object in the issued brief, the route record's `next_step`, and #3992's\n  `research.next_step` are byte-identical under canonical sorted-key compact JSON; one hash\n  `8c6dfa93…`. `depends_on` on the route: #1840 (accepted, verified) and #3736 (accepted,\n  verified); the step's own failure clause says \"Preserve #3736 and #1840\".\n- Offline checker `check_10574.py` re-derives the route state, step identity, comparison classification, sweep accounting and\n  coordination state in 19 named checks from saved bytes, with ten planted in-memory corruption\n  controls (one per guarded quantity), each caught by its own named check.\n\n## E2 — What the setter left open\n\n#3992 is a rescue, not an execution. Its measured content is a data-only index comparison: both\nserved indexes (`ifront959.out` `c8ffeca7…`, `certs_manifest_ci.tsv` `c8ad420f…`) contain the same\n40 old support/prefix pairs, supports 9409..243682, and **none** of the 40 proposed fresh supports\n1210809..1445082. Its own text: \"The inspected route and repair inventory contain no result\nanswering the proposed fresh-block experiment.\" The step it wrote asks for exactly the parts that\ncomparison shows missing: (1) build and freeze the fresh support/prefix manifest for\na = 9409+6007k, k = 200..239, derive candidate `n_cov` with the predecessor frontier method,\nretain exact covering phase vectors at `n_cov`, require independently checked trees at `n_cov+1`\nbefore claiming exact frontiers, preserve unresolved endpoints, verify actual interval\ndisjointness; (2) review/hash manifest-driven adaptations of `run_supports_ci.py` and\n`analysis_ci.py`; (3) freeze all R1/R7 prediction sets, solver versions, policy definitions and\nevaluation rules before observing root labels; (4) compare the `tree959.py` local-lookahead\nselector with a root-only intervention choosing the smallest prime in argmax M(q) under identical\ndescendant rules, all 19 legal domains, all phases including zero, exact leaf checks, depth cap 8\nand resource caps, alternating execution order, with full cost accounting.\n\n## E3 — The comparison set, read at served bytes\n\n  All 25 post-setter returns named by the brief were fetched (authenticated reads, each HTTP 200,\n  all created after 2026-10-15T13:56:55Z) and scanned for the step's vocabulary:\n\n  - **#4023, #4032, #4055 (route 7)** carry the instance vocabulary (`tree959`, `ifront959`,\n    `n_cov`, `9409+6007k`) because route 7's held step (#2167) is set on the *same frozen\n    instance* (p = 97, Q = 101..193, #1840's supports) using #1840's instruments. They answer\n    **route 7's** question, not route 4's: #4023 and #4032 are route-7 step checks (`promising`,\n    step `db3d7cf0…` copied exactly), and #4055 (route 7 pursuit, `result`, accepted, measured)\n    wrote the 163 missing depth-1 certificates at `n1` and measured depth-2 conditioning closing\n    39 of the 79 remaining integer-frontier gap slots **on the old 40 supports of\n    `ifront959.out` (k = 0..39)**. #4055's served bytes contain **zero** occurrences of the\n    route-4 step's action vocabulary (`capacity-max`, `argmax M(q)`, `root-only`, `root policy`,\n    `1210809`, `1445082`, `fresh support`, `prefix manifest`, `run_supports_ci`, `analysis_ci`,\n    `R1`, `R7`); its seven `manifest` occurrences are its own `d2_certs_manifest.tsv` and quotes\n    of #3736's `certs_manifest_ci.tsv` (the old index). No fresh block, no root-policy\n    comparison, no R1/R7 freeze, no manifest-driven driver adaptation. The next return,\n    **#4056** (2026-10-15T20:04Z, recorded, no route), is an **applicability screening of\n    #4055** — administrative relevance triage that runs nothing and quotes #4055's report for\n    its instance mentions; it answers nothing.\n- **#4020 (route 8)** and **#4521 (route 2)** each contain exactly one `tree959` occurrence,\n  inside quoted route-record prose (#3992's own summary text repeated in their briefs) — not\n  their own work.\n- **#4028 (route 8)**, **#4545 (route 2)**, **#5238 (route 140)** and the remaining 17 linked\n  returns (G2 ladder and lane-formalize studies #4482, #4491, #4497, #4519, #4533, #4539, #4663,\n  #4690, #4727, #4800, #4870, #4875, #5135, #5255, #5264, #5267, #5280) carry **zero** step\n  tokens of any kind.\n- The 13 open findings named by the brief (mixed-level-notes.md, first-slot-notes.md,\n  research/G2-STATE.md ×5, research/OUTCOMES.md, difftest.py, results.md,\n  research/ladder/SOUNDNESS.md, scores.py, check_audit.py, AUDIT.md) were fetched; **zero** step\n  tokens across all finding notes.\n\n## E4 — Bounded public sweep and coordination state\n\n  (1317 ids: 564 HTTP-200 bodies + 753 404 gaps, all accounted) was token-screened for the step's\n  action and instance vocabulary, with bare `R1`/`R7` screened separately because they are not\n  distinctive.

The bare `R1`/`R7` hits\n  (#4025, #4037, #4093, #4102, #4114, #4192, #4199, #4274, #4314, #4333, #4347, #4372, #4378,\n  #4446, #4531, #4555, #4565, #4824, #4825, #4887, #4922, #5003, #5057, #5062, #5073, #5082,\n  #5094, #5140, #5258, #5282, #5290) were each inspected in context and are other meanings\n  entirely: a `substitution-R1` lemma label, checker check-labels (`R1`–`R14`, `R0`–`R4`,\n  `R1`–`R7 PASS`), #4314's and #4887's scoped-observation labels (R1)(R2)(R3), reviewer-round\n  labels, register row labels (`R7`–`R16`), a route-192 threshold name, the mathematical symbol\n  `R1(5)`, substrings of `COR17.md` and `min_cover_exact`, and route-230/192 step-text quotes;\n  none is route 4's prediction set.

No mathematical claim is made: nothing\nhere bears on coverability, H_alpha, proof length or the conjecture; #3736 and #1840 remain the\nroute's accepted finite premises, rejected #3711 stays rejected, and #4055's capped depth-2\nsearch stays a route-7 lower bound.

No lane-chat endpoint resolves (404s; the reviewed adapter has no messaging command) and today's comparable step check (#5238) cites no channel message; per the brief the return itself is the completion note.\n\nE5 Conclusion. No step component is answered on record: no fresh manifest for k=200..239, no hashed manifest-driven driver adaptation, no frozen R1/R7 prediction set, no two-policy root comparison on any block. known is unavailable; progress would invent a replacement; the held step is well posed, so it is copied exactly as next_step.

Route #4's next experiment was set by return #3992, and returns were recorded after it on this route or a route linked to it by citations, dependencies or shared premises. Before a pursuit is spent on it, decide whether the returns already on record answer it. Read and compare; do not run the experiment and do not reproduce a computation a return already made. An unchanged-step comparison on another route is not new evidence.\n\nThe step:\n{\"method\":\"Build and freeze the missing fresh support/prefix manifest first. Derive candidate n_cov with the predecessor frontier method; retain exact covering phase vectors at n_cov and require independently checked trees at n_cov+1 before claiming exact frontiers. Preserve unresolved endpoints and verify actual interval disjointness. Review/hash manifest-driven adaptations of run_supports_ci.py and analysis_ci.py: their original ifront959.out covers only k=0..39. Freeze all R1 and R7 prediction sets, solver versions, policy definitions and evaluation rules before observing root labels. Compare the existing tree959.py local-lookahead selector with a root-only intervention choosing the smallest prime in argmax M(q); descendants, all 19 legal domains, all phases including zero, exact leaf checks, depth cap 8 and resource caps remain identical. Alternate policy execution order. Record every certificate, failed/censored run and retry. Count preparation, capacity work, candidate-scoring and descendant LP calls, integer checks, certificate bytes and independent verification; charge shared preparation equally in policy comparisons but only once in actual accounting. Measure process CPU separately from wall time. Report R1/R7 label agreement descriptively, not as a uniform-root significance test. Compare matched per-support and aggregate full work; do not infer time savings from LP counts or global optimality from two policies. Reuse the repaired old census from #3736 rather than rerunning it.
