- Utils::LookupTableContext: the lookup-table counterpart to AccountContext — table registry, v0 loading rules (never signers, the fee payer, or invoked program ids; first table wins; runtime loaded-address order), and the AddressLookupTable references a v0 message carries - AccountContext#relocate_loaded_accounts: rebuilds a compiled account list into the combined v0 account space [static, loaded writable, loaded readonly] and adjusts the readonly-unsigned header count (calculate_header and merge_from compacted to stay within the class-length limit) - Connection#get_slot Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
TransactionComposer#add_lookup_table registers an on-chain table (address + full ordered address list). Registering a table opts the transaction into the v0 format, matching @solana/web3.js: compose_transaction loads every eligible compiled account through the tables instead of a static account slot and rebuilds instruction indices against the combined v0 account space. With no tables the legacy path is untouched. Unit tests cover v0 emission, the static/loaded split, header adjustment, table references, index resolution, serialization round-trip, and the legacy path; a validator-backed test provisions a real lookup table (create + extend via test-support composers for the ALT program) and lands a v0 transfer through it.

- Transaction composer page: add_lookup_table + lookup_tables entries and an "Address lookup tables (v0)" section - ALT concepts page: composer example; scope tip now reflects that composing v0 transactions from existing tables is covered - Account context page: the v0 relocation step - Connection page: get_slot Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

Adds address lookup table (v0 transaction) support to the composer layer and bumps the gem to 0.1.8:
TransactionComposer#add_lookup_table(account:, addresses:)registers an on-chain table; registering a table opts the transaction into the v0 format (matching@solana/web3.js):compose_transactionloads every eligible compiled account — non-signer, not the fee payer, not an invoked program id — through the tables and resolves instruction indices against the combined v0 account space. With no tables, the legacy path is byte-for-byte untouched.Utils::LookupTableContext— the lookup-table counterpart toAccountContext: table registry, v0 loading rules (first table wins, runtime loaded-address order), and the message'sAddressLookupTablereferences. Program ids are derived from the built instructions, so composers that emit multiple instructions for different programs are covered.Utils::AccountContext#relocate_loaded_accountsrebuilds the compiled account list into[static, loaded writable, loaded readonly]and adjusts the readonly-unsigned header count. Note: the small compactions tocalculate_headerandmerge_fromare there so the class still fits theMetrics/ClassLengthcop after the new method — no behavior change.Connection#get_slotSelection rules, ordering, and wire format verified against the versioned-transactions spec, the Rust SDK message compiler, and web3.js
