# Merge 01 — batch r6-j5-joint (J5 continuation items k01-k10)

Deterministic merge of the ten item results under `.imd/reads/artifacts/`. `result_sha256` is the sha256 of each item file. Numbers are rounded to 6 decimals in `rows` (exact values in the item files). `over_T`/`over_base` are replica holdout over 8192 seeds; `over_base` is over J5 (the start point). `vs_IB` is the real-engine candidate-minus-IB mean on paired seeds.

## Summary
- Only k02 ran a search (60.5 min, 96 generations); its best point is +0.0198 se 0.0046 over J5 on the replica holdout and +0.583 se 0.034 vs IB on real seeds. That is far short of the ~+3.1 over HA needed for the top 10.
- The other nine items fell back to real-only (replica below 500 markets/s) and measured the unchanged J5 vs IB: +0.507 to +0.577.
- k05, k06, k08 are marked valid=false by their authors (reasons in notes). No OOG anywhere; afterSwap peak <= 239,071.

  "No item reached the goal: k01,k03-k10 skipped search because the warmed 512-market replica speed measured below the brief's 500 markets/s cutoff (122-375/s on those machines); they report the unchanged J5 (code sha256 dd53db1f...b38c, same as the J5 `code_zb64` hash given in the brief) against IB on real seeds. Only k02 (555.7 markets/s) ran a search.",
  "k02 search: pycma CMA-ES, popsize 32, 219 dims (178 weights + 41 constants), 96 generations, 60.47 min, 49,152 training markets. Monitor-set gain over T went 2.3568 (J5 start) -> 2.3752 at 60 min; best 2.3840 at 50.0 min (selected point; +0.0272 over J5 on the 2048-market monitor). Holdout (8192 seeds 40000000-40008191): +2.3274 se 0.0134 over T and +0.0198 se 0.0046 over J5 (replica). Real vs IB: +0.583 se 0.034 on 1024 seeds 8304000-8305023, against +0.51 to +0.58 for J5 alone in the other items (different seed blocks, unpaired comparison; the difference is within noise). The gain over J5 is a small fraction of the ~+3.1 over HA needed for the top 10; no top-10 or leaderboard claim is supported.",
  "Were the curves still rising? k02's monitor curve is noisy and non-monotone (2.349 at 5 min, 2.339 at 10, 2.339 at 15, then 2.355-2.384 from 20 min on, peak at 50, 2.375 at 60) with sigma decayed to 0.25; it rose slowly and was not clearly still rising at 60 min, so the pilot's 'still rising' observation is not confirmed by this single 60-minute run. Other items have no curve (k03/k05 hold only the J5 starting point 2.3568).",
  "Replica gates: Gate A/C (port vs EVM fees) passed everywhere with max diff 5e-5 to 4e-4 bps (< 0.01 / < 0.1 bps); Gate B (replica J5 minus IA = +0.8655 se 0.0338 vs real 0.876, error 0.0105, limit 0.15) passed in all items that reported it. Gate A/C used each item's own bounded synthetic or replica-market callback generator, not a common one. Gates A and C were the same comparison in the real-only items because the frozen candidate is the unchanged J5 and port. k09 marks Gate C 'not applicable'.",
  "Failures seen: k01, k02, k03, k04, k05, k07 and k10 report that an unbounded/stress synthetic callback generator reverted with Solidity Panic 0x12 (division by zero) when reserves collapsed (k05/k10: seed 310037, callback 1424, reserve_x ~0.117, reserve_y ~8.5e6). This was not OutOfGas and did not occur in real-engine runs; it means arbitrary-input robustness is not certified. k05 and k10 record it as a failed 'synthetic_stress' check.",
  "Validity differences: k05 valid=false: 64 IB real results (seeds 8316400-8316463) were lost before serialization and never rerun, so only 960 pairs and no gas for that chunk (the IB gas counters cover 960 markets). k06 valid=false (candidate_checks_valid=true): two short API smoke runs touched seeds 8320000-8320001 of the primary range; its fresh-seed confirmation (8320002-8321025, n 1024) gives +0.5780 se 0.0310. k08 valid=false (candidate_safety_valid=true): the first 64 J5 real seeds were rerun after a JSON serialization failure (first run discarded, final aggregation counts them once). k10 reran 64 J5 seeds for the same persistence reason and excluded duplicates; k10 and k04 mark valid=true. k07 valid=true by its own narrower definition (bounded gates and gas). k03 and k05 retail/arb edge decomposition is partial (k03: 960 seeds; k05: 798 seeds); k01 decomposed all seeds (retail -0.518, arb +1.033 edge delta vs IB).",
  "No OutOfGas, revert, other_halt, tx_error or bad_return was recorded in the real-engine gas_stats of any item. afterSwap peak 237,573-239,071 (<= 245,000 limit); k02's 239,071 is the highest. k06 also reports an extra fresh extension with peak 206,424.",
  "Retail/arb deltas: the installed wheel exposes no edge split, so most items give Y-volume deltas (retail about +53 to +80, arb about -125 to -177 per market, J5-or-candidate minus IB). Only k01 (all seeds) and k03/k05 (subsets) derived edge deltas by reconstruction; k02 gives replica holdout edge deltas (vs T: retail +4.643, arb -2.316; vs J5: retail +0.119, arb -0.099).",
  "Pooled real-only J5 vs IB, computed by this merge from the per-item sum/sumsq above (different seed blocks, treated as independent): all nine items n=9152 mean +0.5357 se 0.0092; the six items marked valid (k01,k03,k04,k07,k09,k10) n=6144 mean +0.5294 se 0.0113. All numbers are local measurements, so the J5 gain over IB is about +0.53 and was not measured by these items against T or HA on the real engine (k09 states this explicitly).",
  "Source reliability: the platform flagged sources in every result (k01 2, k02 2, k03 3, k04 1, k05 3, k06 1, k07 2, k08 1, k09 2, k10 2) as not holding on re-read (page unreadable or not saying what was quoted). The items state that their speed/gate/holdout/real/gas figures are local measurements and cite sources only for input provenance (artifact ids, sha256 hashes, setup commit 6b6921f8..., wheel aedb6828...). I did not re-fetch those pages. The provenance claims (hashes agreeing with the brief's) and the reference real gain 0.876 for Gate B therefore rest on flagged sources and should be treated as unconfirmed; the numbers themselves are unaffected by that. The brief's own figures (HA +1.257 over T, top 10 needs about +3.1 over HA) were not independently re-measured.",
  "Mode difference: k09 reported no holdout (no search); its holdout fields are null. Several rows list last_curve_point null because there was no curve; k03 and k05 list the single starting point. Replica-side T is mean_edge ~524.97 vs J5 ~527.28 in k08's holdout.",
  "The k02 candidate's Solidity/code hash d58782fc...ff25a was verified here by decoding its code_zb64 (base64+zlib) and hashing; that matches its stated code_sha256. The sha256 of the base64 string itself is e2662311...97e6. The k01-k10 result file hashes in `result_sha256` were computed by this merge and match the hashes in the task inputs. Item k01 params contain an extra 'architecture' key not present in k02's."
