Mirrors the four learning-examples commits (9b48418,c25e2ed,57ffe8b,ad6d2cc) into the production code paths under src/. Affects only pump_fun; lets_bonk untouched. PumpSwap is not implemented under src/ so the pool-v2 + breaking-fee-recipient pumpswap accounts are out of scope here. Changes ------- src/platforms/pumpfun/address_provider.py - Adds BREAKING_FEE_RECIPIENTS: ClassVar[list[Pubkey]] with the 8 addresses pump.fun published for the 2026-04-28 upgrade. - Adds pick_breaking_fee_recipient() (random.choice across the 8 to spread program-tx throughput per pump.fun's recommendation). - get_buy_instruction_accounts and get_sell_instruction_accounts now expose "breaking_fee_recipient" alongside the existing keys. src/platforms/pumpfun/instruction_builder.py - BC buy ix: appends breaking_fee_recipient (mutable) AFTER bonding_curve_v2 → 18 accounts total (was 17). - BC sell ix: appends breaking_fee_recipient (mutable) AFTER bonding_curve_v2 for both cashback and non-cashback paths → 16 accounts non-cashback / 17 cashback (was 15 / 16). - get_required_accounts_for_{buy,sell} updated to include the new account so priority-fee scraping covers it. src/platforms/pumpfun/event_parser.py - is_mayhem_mode now extracted into TokenInfo on both paths (CreateEvent logs path and create / create_v2 instruction path); previously only is_cashback_coin was carried forward, leaving extreme_fast_mode buys to use the wrong fee_recipient on Mayhem-Mode tokens. src/trading/platform_aware.py - Buy non-extreme path now also refreshes is_cashback_coin from pool_state (was only refreshing is_mayhem_mode). - Sell path now refreshes both flags from curve state before building the sell ix, so a coin that flips cashback after buy still gets the correct 16-vs-17-account layout. Wrapped in try/except so a transient RPC failure logs a warning and falls back to token_info defaults rather than failing the sell outright.
