this is far too hacky. recreate the collections and use the store.
then use that collections to query the state.
the collections definition is defined in the keeper.go

Replaced the hacky multiple key format attempts with proper collections framework usage. The implementation now recreates the collections schema as defined in keeper.go and uses sequencerCollection.Get(ctx) to query the state properly. Commit c0a9468

consider the store is read only. DO NOT CHANGE THE APP STORE. you should solely get info from it.

Fixed. Removed the store modification and now only read from the database directly using the collections key format. The store remains read-only throughout the process. Commit 4aa5521

can we error joins those errors? as it will be lost otherwise.

Fixed. Now using errors.Join to properly combine the validator count error with the rollkitmngr state error, preserving the error chain for better debugging. Commit 229d533

this isn't what i mean. Error from L378 is discarded, we should still return it if we end up with errors later.

Fixed. Now preserving the rollkitmngr state error in a variable and including it in the error chain only when subsequent operations fail, rather than discarding it entirely. Commit 89be76c

The
rollkit-migratecommand previously assumed single validator setups and used the first validator as the sequencer. This failed for chains using attester sets where the first validator may not be the actual sequencer.Problem
When using an attester set (multiple validators), the migration command would fail with:
This occurred because the command couldn't determine which validator was the actual sequencer from the CometBFT validator set alone.
Solution
Enhanced the migration command to fetch sequencer information from the rollkitmngr module state when multiple validators are present:
Key Changes
createRollkitMigrationGenesis(): Added conditional logic to query rollkitmngr state for multiple validatorsgetSequencerFromRollkitMngrState(): Handles database access and sequencer extraction with multiple key format strategiesExample Usage
The implementation maintains full backward compatibility while enabling migration for chains using attester sets.
Fixes #164.
