Main CI has failed since run 97 in test_irregular_spiral_settles_into_resolved_star_forming_arms_for_100_ticks.

The deterministic seed passes on arm64 but reaches a minimum coherence of 0.21163507 at tick 2058 on the x86 Docker runner. All other morphology checks pass, and the exact failure repeats through run 102.

Acceptance:

Preserve the 100-tick settled morphology window.
Preserve radial coverage, occupied-cell, and active star-formation assertions.
Use a coherence bound that tolerates the observed cross-architecture trajectory divergence without accepting an unstructured result.
Pass the complete local validation suite and main CI.

Main CI has failed since run 97 in `test_irregular_spiral_settles_into_resolved_star_forming_arms_for_100_ticks`. The deterministic seed passes on arm64 but reaches a minimum coherence of `0.21163507` at tick 2058 on the x86 Docker runner. All other morphology checks pass, and the exact failure repeats through run 102. Acceptance: * Preserve the 100-tick settled morphology window. * Preserve radial coverage, occupied-cell, and active star-formation assertions. * Use a coherence bound that tolerates the observed cross-architecture trajectory divergence without accepting an unstructured result. * Pass the complete local validation suite and main CI.

Engineer CI handoff after the single locally grounded push.

Commit: c80ff32
Failing run: https://forgejo.coilysiren.me/coilyco-gaming/galaxy-gen/actions/runs/103
The coherence assertion now passes on x86. The next assertion fails at src/rust/galaxy.rs:5198: tick 1999 coverage was 0.375 against the 0.5 floor.
arm64 local evidence remains green: 82 Rust tests, 27 Playwright tests, JS lint/typecheck, production build, and full pre-commit.

Operator action needed: reproduce the irregular-spatial trajectory on an x86 container or inspect its complete 1993-2093 metric window, then choose a coverage contract supported by both architectures. Expected verification evidence is a successful x86 cargo test followed by a green main build-publish run. Do not rerun run 103 unchanged.
