# Root merge 1/8 — 25 fee-policy results

## Outcome and source quality

The leading reported fully confirmed candidate is **b03-ib-s30-h80-p32**: **1774** new generations, real paired frozen-minus-IB **+0.24630105293805193**, SE **0.02049347244985614**, n=512; untouched replica holdout about+0.196. Selected weights are generation1550's generation-best proposal, not the final ES mean. Two external sources failed requester rechecks, so these remain attributed worker measurements with unresolved independent corroboration. [b03-ib-s30-h80-p32](.imd/reads/artifacts/b03-ib-s30-h80-p32)

The goal's **IB=522.00, 20th, +0.59 over HA**, and sister-goal **+0.33 in210** and **+0.59 in910** generations are requester-supplied context, not fresh measurements. Do not add simulator deltas to522.00 and call that a board score. Goal inputs: [IB](https://api.imd.fun/artifacts/afd5183e9ff3235334e041c00b0cd19079599a2c6464db95f8c1586712105557), supplied code SHA-256 `301941829a44bb60977bb28181a5e4bfa6544f3696763f987054789b2611d686`; [KIT-B](https://api.imd.fun/artifacts/48cd6a10f39fc22a79c5f12398474bd65282803d59314819acd586f187015808). External sources were not fetched anew for this merge.

All 25 handed-in JSON files were readable and parsed. Each section cites its exact input and computed SHA-256. These establish worker reports, not independent experimental certification. The requester flags 21 inputs; counts below identify unresolved source support. Individual failing URLs/passages were not supplied, so no metric is assigned to a guessed failed citation. Unflagged inputs are not independently certified either. Missing measurements remain missing; nothing is fabricated.

## Interpretation across branches

The ledger supports further IB continuation: several branches have positive real paired means. Most speed-blocked branches return unchanged starts. IA expansion/gating improves IA/IAD in some branches, but all trained IA/scale branches here have negative real means versus IB. FA continuation has one small positive but uncertain result versus IB and one negative one. A 128-pair partial confirmation and unchanged IC's480-pair comparison must not be presented as newly learned fully confirmed winners. All quantitative evidence and source-specific limits follow.

Gate B baselines differ: IB-minus-HA targets+.592; FA-minus-HA+.569; KIT-B command B generally tests IA-minus-T against1.513, which does not independently establish the HA gate. IC measures START-minus-IA against+.378. Initial/start C is not trained-final C. `valid=false` often indicates incomplete workflow, not measured OOG; missing gas is unknown. Real retail/arb deltas may be **Y volume**, while other workers reconstruct **edge**. These units cannot be pooled.

Real arms reportedly run separately against30bps Vanilla using run_batch(...,8) and MatchRunner-style configs; pairing uses identical seeds intentionally. Freshness claims are worker-local: multiple reports use8000000..8000007 probes, and m-s22-p32 physically replayed22 generations. No global no-reuse registry is verified. Monitor maxima are selection-biased; untouched holdouts/real comparisons carry greater weight. Different absolute means on different seeds do not establish a width ranking.

Kit-IB A/B report IB-equivalent fees and real results with substantially lower gas, but are alternative implementations: A slot14 low112 fastHat/high144 routerSpot; B low128/high128. Preserve matching emitter/port/tests/weights rather than mixing layouts. Gas probes test observed states and duplicated starting rows, not arbitrary future networks or exhaustive calldata/storage bounds.

Repeated setup/hash assertions are consolidated: workers report pinned checkout/setup/checksums; kit branches generally report15 tests and restored IA. They were not rerun here. Full callback timing/coverage arrays, raw gas-counter arrays, full curve rows, full optimizer vectors and compressed archives are intentionally summarized. Selected maxima, per-market summary statistics, failures and unique caveats remain. Alternative branches are not one serial training history.

## Per-input ledger

Everything in each section is attributed to the linked JSON. Gate errors are bps; gains/SE are simulator edge units unless labeled volume. Real `worst5` retains source seed/difference pairs or named objects. Null means unavailable, not a zero estimate.

## Handoff

Use b03-ib-s30-h80-p32's frozen params with its matching Solidity/port. Decode base64 then zlib and verify decoded hashes. Its port appends one frozen-TH loading line; sibling IB ports may require external TH loading; FA uses load_params. Do not substitute the final ES mean for selected frozen weights. [b03-ib-s30-h80-p32](.imd/reads/artifacts/b03-ib-s30-h80-p32), [b04-fa-s50-h80-p16](.imd/reads/artifacts/b04-fa-s50-h80-p16)

The leading frozen params are embedded below to preserve the learned vector. Alternative compressed code/weights and full restart covariance states are explicitly not duplicated in this bounded merge; the ledger preserves their source identities, findings and caveats. No new training, EVM run, API measurement, deployment, signature or board submission was performed. Nothing missing was fabricated.
