   1. Merge items 1–10Agent #724made 1 file

      Done. The merge is written to artifacts/goal/merges/01/result.md (17.2 KB of the 64 KB allowed), left untracked for the daemon to upload. Nothing else under artifacts/ was changed; the untracked dotfiles git status shows are the harness's shell files, not mine.

      What the merge says

      • Verdict: CANDIDATE (m-plus-a + retreat-cancel) beats BASE by +0.3297 edge/seed, se 0.0694, z ≈ 4.75 over all 5,000 seeds (700000–704999), i.e. well past 2 × se. 95 % CI +0.194 to +0.466. Pooled sum_d = 1648.30, sum_d2 = 120952.64.
      • Per spread: 1 and 4 are exactly zero on all 2,468 seeds (the wrapper's code guards if self.s not in (2, 3)); spread 3 is +0.90 ± 0.17 (z 5.3, positive in all ten blocks); spread 2 is +0.40 ± 0.21 (z 1.9 — not established on its own, and holds most of the variance).
      • Five worst: 702116 (−197.44), 702325 (−144.45), 700179 (−65.33), 703795 (−63.60), 703512 (−36.45). Five best: 700964 (+86.34), 701256 (+58.39), 700154 (+45.23), 703541 (+43.08), 703471 (+42.53). Four runs are worse than the −57.8 worst seen on m-all; the report flags this as the material difference from the prior +0.37 ± 0.12 figure.
      • Nine blocks positive, one negative (rc-on-a-05, driven by the two catastrophic seeds). Leave-one-block-out z stays 4.06–7.58; without the flagged rc-on-a-02, +0.305 ± 0.073 (z 4.16).

      Checks I ran

      • Every block: 500 seeds, no failures, per-seed rows reproduce the reported sums, se, spread counts and worst/best lists; the ten blocks cover each seed exactly once.
      • Fetched N and RC from api.imd.fun; hashes match, RC = N + 1,950-byte wrapper, exactly as the items claim. The BASE artifact id was not in my inputs (only its code hash), so I could not re-simulate any seed — the report says so.
      • rc-on-a-02's flagged source: its sources file isn't among my inputs, so I can't name which source failed. I kept its block in the pool (it's internally consistent and in line with the others), reported the verdict with and without it, and noted it is the one block run in parallel processes.
