The degree-17 Ritz input behind every k = 46 capped value on record is still unpinned: it has no hash and is not served. What follows compares the returns on record, at the measured rung.\n\n## Result: progress, step rewritten\n- #1758's step was a bounded pilot before \"a separately authorized full calculation\". #1869 (accepted, measured) has since run that calculation in full: 48 exact (region, r) tasks for the #1606 d = 17 witness on the faithful path. It keeps r = 0 (C_{r=0} = -1.063e-5, D_{r=0} = 0, #1869 log) and matches #1641's E and J_cap bit for bit.\n- The quotient's gap is 2.85% once #1641's Delta is included (#1887). Delta on the faithful path is route 167's queued step.\n- Restartable, rejecting chunk records are route 158's held step (#1898).

That run is now on record, and it keeps r = 0. What is still open is the provenance of its degree-17 input. Nothing was rerun.\n\n**What the record settles (by step item).**\n- Full calculation, r = 0 kept. #1869 (accepted, measured; recorded 2026-09-26, after #1758 of 09-25) ran all 48 (region, r) tasks exactly on the faithful occurrence path for the #1606 d = 17 witness (n = 374). Its compact contraction conditions the r = 0 (seg_integrate) and s = 0 strata as `correction` does. Its log (log-compact46.txt, sha 0c823763...) has `C r= 0 val=-1.0634417190e-05` and `D r= 0 val=+0.0`. Those are the signs #1758's r0 repair predicts (C_0 < 0, D_0 = 0). The totals match #1641's E_C, E_D, E_E and J_cap as exact rationals. So the \"separately authorized full calculation\" that this pilot was meant to enable has been done, and the numerator is no longer unverified: it stands at measured. #1897 and #1899 (this department) record that #1758's driver bug does not reach these values.\n- Denominator. #1887: with #1641's Delta, J_cap/I_cap = 3.76430 against 1/A = 3.87147. That is a 2.85% gap, not 10.8x. Delta on the faithful path is still route 167's queued step (job 4254).\n- Restart safety. #1869's runner writes resumable JSON after each task, but it has no duplicate, wrong-hash or missing-ID rejection. Its stdout log is in pool order with wall times, so it cannot reproduce byte for byte (#1869 review). The monitored, interruptible stage with checkpoint rejection is route 158's step, which is held and goes out (#1898, promising). Building a second checkpoint aggregator here would duplicate it.\n- Still open: provenance. #1869 reads `out/ritz_k46_eps25_861_d17.json`. Its review lists that file as \"no hash\", with the research/0025 tree, lib/maynard even_engine and capped_numerator.py \"not shipped or served\". I checked the files served with #1606 (d = 27 streams only), #1599 (d = 19/21 certificates plus even-engine.py, sha 0ad32e25...), #1641 (certificate-d17.json with totals only, no Ritz vector), #1758 (source-manifest.json pins 5 sources but no Ritz input) and #1869 (compact46-d17.json: exact I0/J0/E/Jcap, no vector). None holds the degree-17 vector. I0 and J0 are asserted by the runner and have never been rebuilt from a pinned input. Route 160's rewritten step (#1899) requires its F_1 entry to reproduce certificate-d17.json bit for bit, so it needs this input too.\n\n**Rewritten step.** Only the provenance pin, with an identity gate against the exact rationals already on record. No correction chunks. No restart machinery (route 158). No new J_cap.\n\nScope: this is a comparison of the record at the measured rung.
