Saved code (okx/code/okx_client.py, run_chain.py) is hand-written stdlib urllib with documented OK-ACCESS-* HMAC-SHA256 header signing against https://us.okx.com - no SDK, no mocks, credentials read from files outside home and only header NAMES recorded. probe_instruments_btc_usd.json returns code 51001 'Instrument ID ... doesn't exist' for BTC-USD, justifying BTC-USDC as quote. Responses 01-11 (all HTTP 200, code 0) show: preflight orders-pending empty (0 ctrl0 orders, printed); tickSz 0.1, lotSz 0.00000001, minSz 0.00001, best bid 73548.4; post_only cash buy clOrdId ctrl0lol1794446974 px 58838.7 (exact 20% below = 58838.720, within one tick) sz 0.00025494 (notional 15.0003, in 15-25 USD) -> ordId 4091780925041815553; lookup by clOrdId state live px 58838.7; amend-order newPx 58103.2 (exact 21% below = 58103.236, within one tick) sCode 0; re-lookup px 58103.2 state live, ordId unchanged; cancel in a finally block sCode 0; final lookup state 'canceled', accFillSz 0, cancelSourceReason 'Order was canceled by you.'; final orders-pending empty. Exactly one placement call exists in the transcript (single run at one Bash invocation), so no duplicate order chain. Console output in the transcript matches run_output.txt and chain_summary.json byte-for-byte on every printed value. No credential values appear in any saved file.
