Fix several interacting issues that prevented partial state nodes from syncing and following the chain on bal-devnet-2: 1. Stale pivot deadlock: Replace unconditional pivot suppression with rate-limited advances (2-minute cooldown). This prevents the restart loop bug while allowing recovery when the initial pivot is too stale for peers to serve. 2. Storage root resolution: Add snap-based resolver that queries peers for untracked contracts' storage roots during BAL processing. This lets the computed state root converge toward the header root. 3. SetCanonical for partial state: When the computed root differs from the header root (expected when untracked contracts have unresolved storage roots), check HasState(partialState.Root()) instead of only HasState(block.Root()). Guard against zero root during snap sync. 4. Canonical hash backfill: AdvancePartialHead now writes canonical hashes for all blocks between the pivot and snap head, fixing the "final block not in canonical chain" error caused by InsertReceiptChain skipping blocks whose bodies already exist. 5. Gap block processing: After snap sync completes, process accumulated blocks between the sync head and chain tip using their persisted BALs before entering steady-state chain following. 6. Computed root chaining: Use partialState.Root() (actual computed root) as parentRoot for subsequent blocks, not the header root. This ensures correct trie chaining when computed != header root. Tested end-to-end on bal-devnet-2: snap sync completes, gap blocks processed, canonical head advances at chain tip (~1 block/12s). Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
