Description

Ports the Derive maker-flow client (exchange/src/options/derive.rs) from the retired v2 API to v3, so the Derive rows in the GEX Options view (Derive flow 30m, Derive quality) can receive data again.

• Base URL https://api.lyra.finance → https://api.derive.xyz/v3. The existing format!("{}/{}", base_url, method) join keeps the /v3 prefix.
• Trade-history request filter tx_status: "settled" → batch_status: "Settled".
• TradeDto.tx_status → TradeDto.batch_status; the settled-maker filter now checks batch_status == "Settled".
• Test fixture and request-body assertion updated to the v3 field; docs/derive-maker-flow.md updated to the new base URL.

Motivation

api.lyra.finance now answers both REST methods this client uses with HTTP 503, so the panel stays unavailable on current develop builds:

curl -s -o /dev/null -w "%{http_code}\n" -X POST https://api.lyra.finance/public/get_trade_history \
  -H 'Content-Type: application/json' -d '{"currency":"BTC","instrument_type":"option","page_size":1}'
# 503 (checked 2026-10-25)

Derive documents the v3 base and the tx_status → batch_status rename in its migration notes: https://docs.derive.xyz/migrating/breaking-changes

Changing the host alone would not fix it. v3 trade rows no longer contain tx_status, so the required TradeDto field makes every trade-history page fail to deserialize, and v3 silently ignores the tx_status request filter (it returns Batching rows alongside Settled ones).

Type of change

Checks performed

• cargo fmt --all -- --check
• cargo check --workspace --all-targets --all-features --locked
• cargo clippy --workspace --all-targets --all-features --locked -- -D warnings
• cargo test --workspace --all-targets --all-features --locked
• Relevant manual testing described below

Checks were run locally on macOS (arm64) with the pinned 1.95.0 toolchain and RUSTFLAGS="-D warnings" (419 tests passed, 0 failed), plus both bundled indicator validation steps from Develop CI.

Manual testing notes:

• Ran the patched DeriveOptionsClient against live v3 mainnet (BTC and ETH, 2-hour window) through a throwaway integration test that is not part of this PR. BTC returned 628 active instruments and 35 settled maker trades; ETH returned 754 instruments and 73 settled maker trades. Every trade passed is_semantically_valid.
• Checked v3 behavior directly. batch_status: "Settled" filters server-side (50 of 50 rows Settled), while tx_status is ignored (2 Batching rows in 50). Maker trade_ids stay unique (500 maker rows, 500 distinct ids in a 1,000-trade page), so the existing deduplication remains correct. Instrument payloads still carry every field InstrumentDto reads.
• Built and launched a release binary; startup is clean. I did not exercise the GEX Options pane in the UI itself. The client was verified directly against v3.

Unrelated observation, not changed here: cargo test -p flowsurface-exchange on its own fails to compile, because exchange/src/options/quantwheel.rs uses reqwest::cookie while exchange/Cargo.toml does not enable reqwest's cookies feature. It only builds through workspace feature unification, which is why CI does not hit it.

UI evidence

Not applicable. There are no UI changes; the existing Derive rows receive data again.

Compatibility and data impact

None. No change to the persisted DeriveMakerTrade model, the cache format, or saved layouts.

Walkthrough

The Derive API base URL changed to https://api.derive.xyz/v3. Trade-history requests and responses now use batch_status. Trade filtering requires the status to be "Settled" and the liquidity role to be "maker".

Changes: Derive API and trade history

Layer / File(s)	Summary
Update Derive trade-history integration exchange/src/options/derive.rs, exchange/tests/fixtures/derive_option_history.json, docs/derive-maker-flow.md	The configured and documented API URL changed to the Derive v3 endpoint. Trade-history requests, response parsing, filtering, assertions, and fixtures now use batch_status. Missing, null, and non-settled statuses are skipped.
