rotate.gno

 1// Package rotate is a single-use realm shipped at test-13 genesis whose
 2// sole purpose is to swap the gnoland1 sole T1 (`oldT1`) for the test-13
 3// sole T1 (`newT1`) after historical replay completes.
 4//
 5// The proposal-flow rotation pattern (manfred proposes self-withdraw →
 6// new-T1 votes + executes) is unworkable at genesis-mode replay because
 7// gov/dao exposes no API to discover the latest proposal ID across MsgRun
 8// txs — and the post-replay proposal counter depends on how many
 9// proposals manfred opened on gnoland1, which we can't determine
10// statically without re-executing the replay. This realm sidesteps the
11// problem entirely: a single genesis-mode MsgCall to Rotate does the
12// transfer through direct memberstore writes, no proposals involved.
13//
14// Phase-1 bootstrap (`transactions/base/bootstrap/govdao_prop1_test13.gno`) wires this package into
15// `dao.UpdateImpl(...AllowedDAOs)` at lock time, so memberstore.Get()
16// works from inside Rotate. Once Rotate runs it self-ejects from
17// AllowedDAOs, leaving the membership-mutation surface back at
18// `gno.land/r/gov/dao/v3/impl` alone.
19//
20// Single-use is enforced by the `runtime.ChainHeight() != 0` gate.
21// Migration txs run with BlockHeight=0 (forced by
22// `gnogenesis fork generate`'s readMigrationTxs), so during genesis
23// replay ChainHeight()==0 and Rotate proceeds; post-genesis any caller
24// gets a panic.
