argv.rs

//! The clap v4 argv tree and the argv -> [`Command`] mapping (ADR-051 D2).
//!
//! This is the ONE place argv is spelled. The mapping below translates clap
//! matches into the constructor-parsed values of `degenbot-cli-core` and never
//! re-encodes semantics: every arm, flag, prompt and exit code lives there.
//!
//! # Where clap's shape differs from the retired click tree
//!
//! - **`exchange` (ADR-051 D5, 34 click verbs -> one data-driven command).**
//!   Python declared one verb per `(chain, DEX)` pair (`base_aerodrome_v2`,
//!   `ethereum_uniswap_v3`, …). cli-core models that as
//!   `exchange activate|deactivate --chain <slug|id> --name <dex>`, resolving
//!   the pair against [`RETIRED_EXCHANGES`](degenbot_cli_core::RETIRED_EXCHANGES).
//! - **`aave activate|deactivate`.** Python spelled the market as a verb
//!   (`aave activate ethereum_aave_v3`); cli-core takes `chain_id` and resolves
//!   the deployment from [`AAVE_DEPLOYMENTS`](degenbot_cli_core::AAVE_DEPLOYMENTS),
//!   so the tree is `aave activate [--chain-id <id>]` with Python's Ethereum
//!   default (1) when no chain layer supplied a value.
//! - **`aave position show <ADDRESS>`.** The click shape is kept, except that
//!   its chain selector IS the global `--chain-id` (ADR-051 D8) rather than a
//!   second, position-local spelling of the same thing; cli-core's arm takes
//!   the resolved session chain id.
//! - **`--socket`.** cli-core resolves the operator socket through the cascade
//!   `--socket` > `DEGENBOT_OPERATOR_SOCKET` > `~/.config/degenbot/operator.sock`
//!   ([`resolve_socket`](degenbot_cli_core::resolve_socket)); click declared
//!   `--socket` required. The flag is therefore optional here - cli-core owns
//!   the cascade.
//! - **`database reset`.** Python marks it `hidden=True`. The command is
//!   present and visible here (cli-core carries the arm; hiding it would make
//!   the Rust tree the only place the arm is unreachable).
//! - **Flag help text** is the Python help text, so the two surfaces read the
//!   same. The per-flag click `envvar=` fallbacks (`DEGENBOT_CHUNK_SIZE`, …) are
//!   NOT re-added: cli-core models these inputs as argv only, and the only env
//!   vocabulary the console owns is the driver-domain set of ADR-051 D8.
