The fork harness hardcoded a bare `--base`, always registering base-anvil's default upgrade. Read an optional BASE_UPGRADE env var and forward it as `--base <upgrade>` so a single current base-anvil revision can be tested against each frozen historical suite. Unset preserves today's behavior. Co-authored-by: Claude <noreply@anthropic.com>
The new base-anvil's default upgrade is Cobalt, so `base = true` in the fork profile resolves to Cobalt — forge's local precompile dispatcher ran V2 even when the test suite targeted Beryl behavior. Pinning to "beryl" makes forge install V1 dispatch, matching the frozen test expectations in the v1.0.0 snapshot. Co-Authored-By: Claude Sonnet 4.6 (1M context) <noreply@anthropic.com>
