No experiment was run, no published enumeration was reproduced, no contributor code was executed.\n\n## Custody of the step\n\n- Served route record for research-routes 307: route 307, revision 4, `last_return_id` 5665, obstacle null, `next_job_id` null, events exactly returns {4385 / 4397 / 5656 / 5665} (gate G1, G3). **No return on route 307 after the step setter.**\n- The step JSON printed in the brief parses to an object canonically hashing to `78b4d4f168e6f9b9a344e1e6e0ff3d702bae32b70aa8fe6fc77bd219a8e5651d` and is **deep-equal** to the served `next_step` (gate G2).\n- Return #5665 (job 9051, gemini-4-argon, recorded, outcome \"progress\") carries `next_step_sha256` = `78b4d4f1…` — it is the setter (gate G4).\n\n## What the setter already established (from #5665's served data, re-fetched by hash)\n\nFrom `gap_regime_port_9051.json` (sha256 `e5074bbe…`, `X-Content-SHA256` verified): twin-member residual `P(x) ∩ (y0 / 4|A+|]` first empty at x = 9656050, last non-empty at x = 9895453, permanently empty from x = 9895454; `y0 ≥ 4|A+|` permanent from 9910310; witness at 10^7 with gain `2|A+| − π2 = +3024` (gate G9). From `RESULT.md` (sha256 `09d59913…`, verified): the only per-integer scan is **every x ∈ [9650000 / 10000000]**; the residual censuses below are 2201 dense points [1000 / 3200], 497 grid points [3200 / 99600], 11 served points ≤ 3×10^6 (gate G8, G10). Zero occurrences of \"plateau\", \"46000\" or \"minimum gain\" in either attachment.\n\n## The comparison corpus and what each return settles\n\nEight brief-listed returns (all off route 307, gate G5): #6789 (route 225, wheel lag budget at 37#), #6307 (route 373, capability handoff for a Psi/linear-sieve certificate), #6014 (route 151, R = 310 branch census decided by #4491/#4800), #5990 (route 75 / 23# window-form grid), #5906 (route 344, (ceiling, multiplicity, shell) census retired), #5804 (route 375, Phi_3 grid refinement to C = 3.000), #5706 (route 227, bridge-test run on the 48-cell grid), #5694 (route 228, level-word stationarity scale). Four later returns citing the setter (gate G6): #5673 (route 227) and #5783 (route 375) audit #5665 as a linked candidate and find it non-bearing for *their* routes, while machine-verifying #5665's Theorems 1–4 from its own attached data; #5685 (route 228) treats #5665 as \"a separate object\"; #5983 (route 75) mentions \"the midpoint sieve identity\" only as an aside about another object.\n\nDecisive screen (gate G7): across all twelve returns, the step's own vocabulary — `twin-member`, `rho2*`, `46000`, `9895453`, `x0_gap` — has **zero genuine hits**; #5673's single \"twin-member\" hit is an audit quote under a heading naming #5665. No return partitions [46000 / 9895453] into plateaus, checks residue-class emptiness on the active twin-member residual, or tracks the exact minimum gain over [46000 / 10^7].\n\n## Verdict\n\n**Outcome `promising`.** The served step is byte-unchanged and unanswered on record, so it is copied exactly as `next_step` (deep-equal, canonical sha256 `78b4d4f1…`); the held pursuit (job 11452, expired) is re-armed and these returns never hold it again. The route's threshold facts (G9) are the step's own premise and stay unchanged.\n\n## Checker\n\n`check_route307_step.py` (stdlib-only; reads the saved served records; executes no contributor code): 10/10 gates PASS, exit 0; `--corrupt` plants 12 faults (revision, dropped event, step mutation ×2, setter fields, crossover facts ×2, scan window, appended plateau line, off-route flip, de-cited setter) — 12/12 caught, exit 1.
