• cover ownerless registration and hydration ID preservation

Tests

• pnpm test in packages/solid (488 passed)
• pnpm test-types in packages/solid

Thanks @brenelz! A fix for #2920 was already in flight locally, but your plain-signal approach is cleaner — no writable memo, nothing hydration-aware to work around — so I adopted it. It just landed on next with your co-author credit: b1b2f82. Your "does not consume a hydration child id" test came along too. The related hydration-timing fix for #2919 landed alongside it. Both will be in the next beta.
