…sers Add reservation SDK with PDA helpers, instruction builders (InitializeClientSeat, InitializePaymentEscrow, ClosePaymentEscrow), and raw-byte parsers for ClientSeat, PaymentEscrow, DeviceHistory, and MetroHistory on-chain accounts. Part 1 of #274
… and ClientSeat layout - Add FundPaymentEscrowUsdc(u64) instruction variant with discriminator - Add FundPaymentEscrowUsdcAccounts (10 accounts) for funding escrows - Fix ClosePaymentEscrowAccounts: insert execution_controller at index 1 (now 8 accounts) - Update ClientSeat parse offsets for new on-chain layout: flags at 48, funded_epoch at 56, active_epoch at 64, funding_index at 72 - parse_client_seat now returns (device_key, client_ip, tenure, funded_epoch, active_epoch)

#276) ## Summary of Changes - Add `reservation` subcommand behind the `experimental` feature gate with: - `initialize-seat`: create a client seat and payment escrow for a (device, client_ip) pair; skips seat creation if it already exists - `fund`: deposit USDC into a per-seat payment escrow; validates positive amount and checks on-chain minimum price - `withdraw`: close a payment escrow and reclaim USDC; pre-flight check for escrow existence - `list`: show all client seats with optional device, client-ip, and withdraw-authority filters - `price`: show current device pricing (metro base + device premium) - Simplify `ClosePaymentEscrowAccounts` SDK constructor to accept `Option<&Pubkey>` for refund account ## Diff Breakdown | Category | Files | Lines (+/-) | Net | |-------------------|-------|-------------|-------| | CLI commands | 7 | +798 / -0 | +798 | | SDK (constructor) | 1 | +10 / -13 | -3 | | Build / changelog | 2 | +5 / -0 | +5 | ~800 net lines — 5 new CLI commands, subcommand scaffold, and SDK cleanup. <details> <summary>Key files (click to expand)</summary> - `crates/solana-cli/src/command/reservation/mod.rs` — subcommand enum, `DeviceArgs` (shared `--device` / `--device-code` resolution), feature gate - `crates/solana-cli/src/command/reservation/initialize_seat.rs` — sends `InitializeClientSeat` + `InitializePaymentEscrow` in one transaction; skips seat ix if already exists - `crates/solana-cli/src/command/reservation/fund.rs` — sends `FundPaymentEscrowUsdc`, derives exchange key from on-chain DeviceHistory, validates amount against current price - `crates/solana-cli/src/command/reservation/withdraw.rs` — sends `ClosePaymentEscrow`, pre-flight escrow existence check - `crates/solana-cli/src/command/reservation/price.rs` — read-only, joins MetroHistory + DeviceHistory to show per-device pricing - `crates/solana-cli/src/command/reservation/list.rs` — read-only, fetches ClientSeat accounts with discriminator memcmp filter, supports `--withdraw-authority` and `--client-ip` filters - `crates/solana-cli/src/command/mod.rs` — wires `Reservation` variant into top-level CLI - `crates/solana-sdk/src/reservation/instruction/account.rs` — merged `new` / `new_with_ata_refund` into single constructor </details> ## Related PRs - **#275 (SDK)**: merged — this PR builds on it - **#277 (Mock + tests)**: depends on this — adds mock program and integration tests Part 2 of #274
