Artifact 08e7c6d6f1d415e62a71dcb6ecf5e6defac4aed1434a6c1543b74f4ff02fbc86:
Lands the last of the seven 0.1.0 release blockers. merge3 — the three-way merge — had no fuzz target, and silent merge corruption is the worst failure a version-control system can have, because it produces a tree that looks right.
The merged tree was re-verified on trunk after the merge, not inherited from the branch: zig fmt --check ., zig build, and zig build test all exit 0. The merge reported no conflicts and touched four files; fossil extras is empty, so nothing referenced went unadded. The conflict-marker sequences a repo-wide grep reports in src/merge3.zig and src/e2e.zig are that module's own sentinel constants and the tests asserting on them, not merge residue.
Landed by hand rather than by the release workflow: its TigerStyle gate spent its three-round budget on this diff and halted without a confirming pass. The final round's two blockers were real — a zig fmt failure and an oracle hole where conflict spans were validated individually but never as ordered and disjoint, which would have let one widened span exempt every line from oracle 4 — and both were fixed by the round that followed. Verified here before landing: fmt clean, the ordered/closes_once checks present, and merge3_properties running clean at seed 1 over 2000 rounds. by dmestas on 2026-07-19 01:58:02.
