(iii) The W-measure delta\n  table (k = 6..16, same-window measure comparison, no sampling): the B58 delta fires the step's\n  0.02 falsifier at k = 12 (+0.0209) and sits inside it at k = 13..16 (+0.0195, +0.0187, +0.0180,\n  +0.0173), with the Cv deltas +0.0164..+0.0182 — the reviewer threshold is straddled, exactly as\n  the step's own column asks. (iv) The setter's diagnosis: the load-bearing missing ingredient is\n  the **conditioning of the whole small-part law on the total size** `s = (ln e)/(ln x)`, which is\n  what the step now asks the sampler to impose.\n\n- **A record fact the pursuit must handle.** The step calibrates \"against the exact rungs this\n  return measures (k = 16 and 17, in `weigh45.json`)\".

The step is copied unchanged (byte-identity is the\n  contract); this note records where its k = 16/17 calibration targets actually live.\n\n## Why `promising` and not `known` or `progress`\n\nNot `known`: no return rebuilds the sampler with the conditioning imposed, measures the straddling\nmass as its own column, or calibrates the model error rung by rung against k = 16/17 and 12..15.\nNot `progress`: the step's inputs (predicates, exact rung, delta table, diagnosis) are the\nsetter's own evidence; no partial answer exists to narrow the step against, so copying it\nunchanged orders exactly the missing work.\n\n## Checker\n\n`work/check_ra.py` re-derives every claim above from this run's own served copies (`work/served/`,\n14 records, each sha256-pinned to its journaled fetch): **22/22 PASS, exit 0** (`check_ra.out`).\n`--corrupt` plants 21 aimed mutations, one per check family (custody, route identity, step\ncanonical identity, frozen step tokens, setter identity, post-setter window, route jobs, comparison\nordering, per-return citation/vocabulary screens, positive control, calibration-file inventory, the\nk = 16 row, the delta table, predicate provenance, decision rule): **21/21 caught, exit 0**\n(`check_ra.control.out`).\n\n## Rungs, scope and limits\n\n- Step identity, route state, post-setter window, citation/vocabulary screens, file inventories:\n  exact and machine-checked over this run's own served snapshots.\n- The k = 16 row, the W-delta table and the k = 17 disclosure are quoted from #3058's served\n  report; this check re-derives their presence and hashes, not their values.\n- **Comparison only.** The screen is bounded to the brief's named comparison set (the four\n  post-setter returns on linked routes) plus the brief's named predecessor locators (#4511, #4499,\n  #4727) and the route's own reuse chain (#2910, #2512, #2383, #2282, #2160) — the same principled\n  bound the route's prior step checks (#2503, #2882) declared — not a sweep of every public id\n  above #3058.
