BREAKING CHANGE: the sequencer database moves from <home>/rocksdb to <home>/rocksdb-<channel id>; an existing home fresh-starts (with a warning naming the old directory) unless the directory is renamed.
Closes#676.
BREAKING CHANGE: the seen-shard PDA address and its data layout both change, so
every message delivered under the old layout becomes deliverable again at the new
address, and the old shards are orphaned. A fresh genesis is required.
BREAKING CHANGE: `CrossZoneMessage` gains `src_block_hash`, changing the risc0
encoding of `cross_zone_inbox::Instruction::Dispatch` and the inbox image id,
and with it the inbox config and seen-shard PDA addresses. A pending dispatch
record written by earlier code no longer names a registered program, so it fails
production and is dead-lettered rather than delivered. Drain the pending list
before upgrading, or accept that in-flight deliveries are lost.
BREAKING CHANGE: `CrossZonePeer.allowed_targets` is replaced by `allowed_routes`,
a list of `{src_program_id, target_program_id}` pairs. `InboxConfig.allowed_peers`
is removed.
Decentralized-sequencing foundation: a shared chain_state crate (two-tier
head/final ChainState, apply_block, AcceptOutcome, StallReason, and the
absorbed channel-consistency machinery), turn-gated block production, the
publisher follow path for adopted/orphaned/finalized peer blocks, and
persistence that keeps disk order equal to apply order under the chain lock.
Rebased onto dev after #600/#606: chain_consistency is absorbed into
chain_state, the sequencer bootstrap's verify_and_reconstruct is re-wired
onto the two-tier ChainState (reconstruction applies channel history
through the final tier and persists via the follow-path primitives), and
test fixtures adopt the SequencerSetup builder extended with
with_bedrock_signing_key.
