Summary

This PR consolidates the Gravity Oracle E2E surface around two capabilities:

• Binance USD-M indexPriceKlines closed buckets through sourceType=3;
• finalized Polygon Polymarket CTF settlements through sourceType=6.

It adds a combined oracle_demo suite that runs both paths in one Gravity cluster and emits one frontend runtime config.

Combined workflow

The suite:

1. starts deterministic local Binance and Polygon JSON-RPC mocks;
2. registers price and settlement tasks through governance;
3. waits for the JWK observer/consensus path to publish canonical bytes;
4. deploys PriceFeedResolver, PolymarketSettlementResolver, and a binary market;
5. verifies NVDA and TSLA closed-bucket rounds;
6. mirrors a Fed July CTF resolution and settles the Gravity market;
7. writes demo-config.json for the dashboard.

Contract artifact builds are targeted to the source files declared by each Oracle E2E, so unrelated contract tests cannot break the suite.

Continuous-only Binance task model

binance_index_kline_v1 is a long-running feed by definition. The task URI no longer carries continuous=true; the reth adapter rejects both legacy continuous=true and continuous=false so validators cannot disagree between one-shot and continuous nonce semantics.

For each feedId, bucketStartMs and interval are immutable. Use a new feedId when either changes. This keeps delivery nonce, bucket time, and confirmed cursor reconciliation monotonic and addresses the failure mode reported in Galxe/gravity-audit#913.

Follow-up commit 00668611b6 (test(oracle): align demos with continuous-only Binance feeds) updates both E2E configurations, live URI generation, shared test helpers, runbooks, and Cargo.lock. The lockfile now pins gravity-reth commit d8cb206f6 from Galxe/gravity-reth#368.

Run the deterministic combined demo

Build the binaries, then run:

RUSTFLAGS="--cfg tokio_unstable" cargo build -p gravity_node --profile quick-release

PATH="$HOME/.foundry/bin:$PWD/target/quick-release:$PATH" \
  ./gravity_e2e/run_test.sh oracle_demo \
    --force-init \
    --keep-running \
    --demo-config-out ../gravity_price_feed_demo_web/public/demo-config.json \
    --log-cli-level=INFO

A later restart can omit --force-init to reuse cached genesis artifacts.

Expected successful assertions include:

Price feed resolved: feedId=1001 roundId=29720877 price=19612645000
Price feed resolved: feedId=1002 roundId=29720877 price=40117545000
Combined oracle demo resolved: NVDA/TSLA roundId=29720877, polymarket marketId=1 YES claimable=300000000000000000000
Suite oracle_demo PASSED
All suites passed!

Stop the retained cluster with:

bash cluster/stop.sh --config gravity_e2e/cluster_test_cases/oracle_demo/cluster.toml

Live Binance mode

The standalone binance_price_feed suite also supports BINANCE_PRICE_FEED_MODE=live for manual demos. Live mode reads recent closed one-minute buckets from Binance public market data and continues writing subsequent closed buckets. It is intentionally separate from deterministic CI and makes outbound requests.

BINANCE_API_KEY and BINANCE_SECRET_KEY are not required for this public endpoint.

Validation

• RUSTFLAGS="--cfg tokio_unstable" cargo check -p gravity_node --locked: passed against gravity-reth d8cb206f6.
• Both relayer JSON files parse successfully.
• Modified Python hook and URI helper files pass py_compile.
• No continuous=true or continuous=false task URI remains.
• git diff --check: passed.

The full oracle_demo flow previously passed with one deterministic combined test; this follow-up changes only the Binance URI contract and dependency pin. The reth PR independently passes its relayer and execution-layer test suites after removing fixed mode.

Scope boundary

The deterministic E2E proves the complete Gravity transport and contract-consumption path. It does not implement generic intra-epoch dynamic request discovery or automatic mirroring of arbitrary Polymarket UI markets.
