{"id":3609,"job_id":7439,"problem_id":1,"lane_id":3,"type":"explore","user_id":1,"model":"deepseek-v4-flash","provider":"deepseek","report_md":"# Revisit-trigger conformance on the untruncated registry: no served `revisit_when` is met, and three closures now carry an exactly narrowed reopen condition\n\nJob #7439 (explore, first look, route 223, general mode), local run `run-2026-10-14-bt`. Read-only\nrecord work: **no experiment was run, no published computation reproduced, no source re-read**,\n`cpu_hours 0`.\n\n## What was asked\n\nRoute 223's held step (set by #2528) is: fix the obstacle object by fetching `GET /research-routes`\nwith `limit >= total` and asserting `len(routes) == total`, rebuild the obstacle ledger over the\n**31** rows #2528 found, and for each obstacle route R type its `revisit_when` twice — (A) is the\nnamed required ingredient present as a served artifact/source recorded after `R.updated_at`?\n(B) is it satisfied at the obstacle's own stated scope? — enumerating the post-closure returns on R\nor on a route linked to R. Success: at least one row with (A) and (B) both passing, or a full\nnegative listing the returns searched per row. `stop_if`: if the post-closure returns cannot be\nenumerated and the per-route event history is insufficient, record the concrete blocker; a partial\nledger with explicit unknowns is acceptable.\n\n## Result\n\n**The object is 34 rows, not 31.** `GET /research-routes?limit=300` returns `len(routes) = 257` with\n`total = 257` (the page is untruncated), and **34** of those routes carry a non-empty\n`obstacle.revisit_when` — not the 31 of #2528 (which saw 224 routes) and not the 20 of #2518. The\nthree rows newer than #2528's snapshot are routes **229, 256, 259**. The registry is ordered\n`updated_at` descending and `limit` is honoured to `total`, so the object is fixed by the assertion\nthe step names.\n\n**The post-closure window is enumerated from the served record, not guessed.** There is no\nreturns-listing endpoint: `GET /returns`, `/returns?limit=5`, `/return?limit=5` and `/outcomes` are\n**404**, and `GET /board` exposes only a fixed window (`recent` 50 entries, ids 3599 -> 3467;\n`recorded` 20 entries, ids 3599 -> 3541; `recorded_total` 1801) whose `limit`/`recent`/`recorded`\nparameters are ignored. Each **route detail** does carry that route's own `events` with\n`return_id`, `created_at`, `outcome`, `evidence_status`, `final_rung` and `detail.depends_on`. So the\nstep was executed by fetching `GET /research-routes/<id>` for **all 257 registered routes**\n(`fetch_all_routes.py`, journaled, 0 errors) and unioning their events into a served return stream of\n**1422 distinct return ids**. Per-route event counts vary 0..25 with no constant cap, so the\nper-route history is not a truncated page. Linkage used by the ledger: R itself, R's parent and\nchild routes, a route declaring a dependency on one of R's returns, and a return whose\n`depends_on` names one of R's returns.\n\n**Every row is decided: 0 met, 29 unmet, 5 undecidable.** `ledger_bt.json` carries all 34 rows\n(route, state, kind, closure time, verbatim trigger, ingredient class, own return ids, linked routes,\npost-closure candidates on-route and linked, A, B, verdict, basis); `decisions_bt.json` carries the\nhand-typed A/B with the reading behind each. **No obstacle route has a post-closure return on its own\nroute** — no blocked/paused route was extended after its closure. The five undecidable rows (routes\n30, 48, 54, 95, 163) each name the exact missing decision input and the returns to read (see\n`evidence_bt.md`).\n\n**Decisive negatives, with the record that carries them.**\n\n- **Route 90 (ii).** The CDCL/SAT gate was pre-registered *exactly* — #1415 (route 132,\n  2026-09-22) specifies n = 13..17, `R = a(n)` SAT / `R = a(n)+1` UNSAT, ladder 545/617/707/869/965 —\n  and states no CDCL solver was installed here. What ran: #1422 validates the encoding with CaDiCaL\n  1.9.5 at **n = 1..12**; #1433 (route 132's closure) compares MIP against that CDCL at n = 9..12;\n  #1459 (route 144, 2026-09-23) decides **n = 13 and 14** on both sides with a MIP (SAT at 545 in\n  222.6 s / 307.0 s, at 617 in 460.5 s / 27.3 s; UNSAT at `a(n)+1` in 323.9 s / 664.3 s) and says\n  *\"The n = 15..17 levels of the recorded gate were not attempted and are not claimed.\"*; #1464\n  closes `R = a(n)+1` for n = 9..14 by LP-closure DFS. Branch (i) stays unmet: the producer is\n  present (#1098's `check-2043.py`) but #1405/#1411 record no published value above n = 17 recovered.\n- **Route 181.** Post-closure #2349 (route 193, 2026-10-05) probed *this* branch on #2244's\n  instrument at x = 11, 13 with a pre-registered falsifier: the full-Ramanujan inner sum over\n  `a mod d` is identical to the phase-carrying block (the retained band is `a <= 2d/h < p` for every\n  `p | d`); discarding the retained M-phasor phase leaves rank 2 (`s2/s1 = 1.0000`); discarding the\n  dual-kernel phase reaches rank 1 only by collapsing to the bare sieve mask (relFro 5.6e-4 /\n  4.5e-16) with magnitude inflated **x87 / x26**; 3-prime divisors give rank-1 residuals 0.88-0.96.\n  Its verdict: the phase is the arithmetic, not the obstruction.\n- **Route 153.** The trigger needs the hash-pinned 212-witness package. Post-closure #1886 (route\n  154, 2026-09-26) records that #1596 matched 186 = a(40), 212 = a(45) against A008407 and that\n  \"#1604 shows that the 212 certificate's 846-coefficient vector is not printed, so the 212 finite\n  layer cannot be reproduced from the paper\".\n- **Route 39 — the reopen condition is now *narrowed*, not met.** Post-closure #1045/#1048 (route\n  84, 2026-09-18T17:27Z) certify `c*_real(u) < 2` on (4.8, 8] by exact rationals (sixteen pieces,\n  worst 1.889444) and read Proposition 4's constant as `2/theta`, concluding that no sieve upper\n  bound for the shifted almost-primes is below 2 at any `theta <= 1`: the marginal test fails under\n  every admissible level, and only a sub-2 pair constant of **Murty-Vatwani type** could revive the\n  route. #1048's own text says it retires route 39 and the open #1034.\n- **Route 259.** Post-closure #3548 (route 208, 2026-10-13T18:02Z) records that at 23# there is no\n  sign stability and no growth — closing the escalation-word order avenue at 19#/23# — that the\n  residual `z_alt` excess is an artifact of its null's support, and that the remaining named\n  candidates supply no `z_A(L)`.\n- **Route 256.** #3463 proves a floor (`beta >= 1`), not the wanted narrowing below\n  `beta_IV(G2) = 1.7772`; #3255 records the bracket as two-signed in every reading.\n- **Route 73.** Its own closure #1290 reaches K = 371 against the K >= 409 bar; the exact\n  `a(23)/a(24)/a(25)` remain unpublished (#1411 at source; #2528's OEIS revision 2026-10-07 read);\n  no post-closure return reports a covering run >= 2459 at n = 25.\n\n## What this changes\n\nRoute 223's own contribution was the ledger over **20** rows (revision 1) then **31** (its first\nlook). The record now has the **34**-row ledger with every trigger typed, the served return stream as\nits enumeration basis, and — new relative to both earlier registers — **a decided (A) for the rows\nthe earlier passes never examined** (the twelve long-window rows closed 2026-09-14..18: all unmet,\neach with its searched returns listed). It also records that no route was itself extended after its\nclosure, so the corpus's blocked/paused set is not silently stale.\n\nThree closures now carry an *exactly narrowed* reopen condition rather than their original prose:\nroute 90 and route 132 now need **n = 15..17** of the SAT/MIP gate (13 and 14 are decided on the\nrecord), and route 39 needs a **sub-2 pair constant of Murty-Vatwani type** (no sieve input can give\nit). This is the discovery output the assignment asked for: a changed ingredient, stated at the\nobstacle's own scope, for routes whose step-checkers would otherwise re-argue the original triggers.\n\n**Honest scope and limits.** (1) The negative is over the **served linkage graph** — a return that\ncites an obstacle route's return only in prose, without naming it in `depends_on`, is not found by\nthis rule; the twelve \"empty\" rows are empty *under that rule* and say so. (2) The `revisit_when`\nstrings are prose; five rows could not be typed from the served summaries, whose per-event\n`evidence_md` is capped at 4000 characters (median 2551 across 1472 events). (3) The ledger decides\n*state*, never the correctness of a closure: an unmet trigger means the closure is still live on\ncurrent-state evidence, not that the original negative is right. (4) The twin prime conjecture is\nopen; nothing here bounds it.\n\n## Artifacts\n\n`ledger_bt.json` (34 rows, full fields), `decisions_bt.json` (the typed A/B and their bases),\n`check_bt.py` + `check_bt.out` + ten control outputs (`check_bt.corruptN.out`), `build_ledger_bt.py`,\n`merge_decisions_bt.py`, `fetch_bt.py`, `fetch2_bt.py`, `fetch_all_routes.py`, `stream_bt.json`\n(the 1422-return served stream), `deps_bt.json` (route links), `worksheet_bt.txt` (per row: trigger\nplus every candidate with its served evidence head), `research-routes-limit300.json` (the registry\npage the assertion ran on), `next_step_bt.json`.\n\nRe-derivation is offline and stdlib-only: `python3 check_bt.py` -> **319 checks, 0 FAIL, exit 0**;\n`python3 check_bt.py --corrupt 1..10` -> each exits non-zero with a named FAIL (a trigger character,\na dropped candidate, a shifted closure time, a removed row, an unfounded `met`, a truncated registry\npage, an invented candidate id, an edited ingredient class, a served snapshot losing an event, an\nout-of-vocabulary verdict).

Rebuild the obstacle ledger from the untruncated registry (31 rows, see ledger_ea.json).

Type each revisit_when twice -- (A) is the named required ingredient present as a served artifact/source recorded after updated_at? (B) is it satisfied at the obstacle's own stated scope? -- and record a per-obstacle row (route, kind, ingredient_class, trigger quoted, candidate returns, A, B, verdict).
