…579) Also dedupe the three account_put_transaction error mappings into one helper. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
CasperClient reuses a fetched state root hash for up to 5 seconds and forgets it after every transaction it sends, so its own writes are visible to the next read. erc20_on_livenet: 18 -> 2 chain_get_state_root_hash calls out of 39 RPC calls total.

Nodes and sidecars answer HTTP 429 or a -32018 'throttled by the node' JSON-RPC error under a burst of reads; the client now retries such calls with exponential backoff (5 attempts). query_global_state_maybe used to turn every error into None, which surfaced as a misleading 'Couldn't query for entity address' panic; transport/HTTP failures are logged as warnings now, a missing value at debug level.

CasperClient keeps global state and dictionary responses for the state root hash they were read at; a query at a fixed root is deterministic, so this is equivalent to asking the node, and the cache is dropped when the root moves on (TTL or own transaction). A burst of 31 getter calls goes from 64 node queries to 6. get_value / get_named_value / get_dictionary_value / events_count return Result<Option<_>> instead of Option: a node that cannot be asked is no longer reported as a missing value. The livenet host and contract env stop with 'Livenet: reading <what> of <address> failed: <reason>'; the internal 'Couldn't query for entity address value' panics are gone.

wasm-bindgen rejects empty enums, which broke generate-client for every contract without user errors (the whole workspace template). The template CI now runs generate-client too and also triggers on changes to the wasm client crates. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

Layer 2 of 6 of the 3.0.0 party stack (bottom-up: 1 → 2 → 3 → 4 → 5 → 6, bottom is #668). Each layer targets the branch below; merge from the bottom. The top of the stack is the tree verified on OdraVM, CasperVM and NCTL; docs are in odradev/odradev.github.io#58 and #59, the migration guide covers every breaking change.
