- persist a final-tier snapshot (state + meta) atomically with the follow update that advanced it; on boot, anchor `final` on it and replay stored blocks above it as `head`, so a post-restart orphan of a not-yet-finalized block still reverts instead of silently diverging
- correlate orphan/finalize events by block hash: restored head entries carry hash-derived sentinel MsgIds (the real ones are not persisted)
- a finalized block chaining on an unfinalized head entry finalizes that prefix (finality is prefix-monotone)
- warn on (and keep ignoring) a same-height adopted competitor that arrives without its orphan sibling — an SDK-contract breach worth surfacing
- follow path reverts orphans via one batched `apply_channel_update` (single truncate + head re-derivation) instead of a re-derivation per orphan
- remove DESIGN.md, move to task docs instead
- trim very long comments / docstrings
Breaking:
1. Now a lot of wallet commands return `TransactionExecuted`, instead of `Empty`.
2. Sequencer's `getTransaction()` RPC response changed from `tx` to `(tx, block_id)`
Integrates origin/main (per-program-crate refactor) and re-homes the cross-zone messaging feature onto it.
BREAKING CHANGE: Genesis state root changes. This registers six builtin programs
(cross_zone_outbox, cross_zone_inbox, ping_sender, ping_receiver, bridge_lock,
wrapped_token) and seeds their genesis accounts (the wrapped_token authorized
minter config, the per-zone inbox config, and optional bridge-lock holdings).
Building the new cores alongside the existing builtins also enables serde/alloc
for the shared programs build, regenerating every builtin program image id. All
nodes must upgrade together.
Rename os_random field to random_seed per review feedback. Fix tests
that constructed SharedSecretKey with a hardcoded EphemeralSecretKey
instead of deriving it via EphemeralSecretKey::new.
Introduce EphemeralSecretKey as a proper struct with EphemeralSecretKey::new()
that derives esk from SHA256("/LEE/v0.3/esk/" || account_id || os_random || nonce).
Rename witness field from esk to os_random. Simplify encapsulate_deterministic
to accept pre-derived EphemeralSecretKey directly.
