Problem statement

Regression coverage stops short of multihop paths ≥3 hops where more than one leg carries non-zero hybrid / book consumption. Router composition and indexer merge logic can drift without always-on tests.

Evidence / context

smartcontracts/tests/src/limit_order_tests.rs — two-hop hybrid on first leg exists; 3+ multi-leg hybrid called out in TEST_GAP_MATRIX.md (DEX-P1-008).
Indexer GET cap 3 hops (route_solver.rs).

Proposed solution

Add cw-multi-test (and optional indexer integration) scenarios:

BFS/route with ≥3 hops, hybrid on ≥2 legs (non-trivial book_input each).
Assert SimulateSwapOperations ≈ execute totals within tolerance.
Indexer POST/GET merge: hybrid_by_hop length matches hop count; LCD sim succeeds.

Acceptance criteria

Contract integration test: 3-hop (or 4-hop POST-shaped) router swap with hybrid on multiple legs passes sim vs execute.
Indexer test fixture: merged ops + optional LCD mock for 3-hop hybrid solve.
Documented in docs/testing.md.

Priority

## Problem statement Regression coverage stops short of **multihop paths ≥3 hops** where **more than one leg** carries non-zero `hybrid` / book consumption. Router composition and indexer merge logic can drift without always-on tests. ## Evidence / context - [`smartcontracts/tests/src/limit_order_tests.rs`](smartcontracts/tests/src/limit_order_tests.rs) — two-hop hybrid on first leg exists; 3+ multi-leg hybrid called out in [TEST_GAP_MATRIX.md](docs/reviews/20260409T030009Z/TEST_GAP_MATRIX.md) (**DEX-P1-008**). - Indexer GET cap 3 hops ([`route_solver.rs`](indexer/src/api/route_solver.rs)). ## Proposed solution Add **cw-multi-test** (and optional indexer integration) scenarios: 1. BFS/route with **≥3 hops**, `hybrid` on **≥2** legs (non-trivial `book_input` each). 2. Assert `SimulateSwapOperations` ≈ execute totals within tolerance. 3. Indexer POST/GET merge: `hybrid_by_hop` length matches hop count; LCD sim succeeds. ## Acceptance criteria - [ ] Contract integration test: 3-hop (or 4-hop POST-shaped) router swap with hybrid on multiple legs passes sim vs execute. - [ ] Indexer test fixture: merged ops + optional LCD mock for 3-hop hybrid solve. - [ ] Documented in [`docs/testing.md`](docs/testing.md). ## Priority **P1**

Implementation summary (GitLab #192)

Added regression coverage for ≥3-hop router paths with hybrid on ≥2 legs (L8 quote vs execute parity), plus indexer route-solve fixtures for 3-hop POST/GET hybrid merge.

Contract (cw-multi-test)

New setup_router_abcd_env harness (A→B→C→D chain)
New test router_three_hop_two_legs_hybrid_matches_simulate — hybrid on hops 1 & 2, pool-only hop 3; asserts SimulateSwapOperations == execute and ≥2 limit-book fills

Indexer integration

New seed seed_route_solve_3hop (A→B→C→D pairs)
route_solve_post_three_hop_multi_leg_hybrid — POST hybrid_by_hop length 3, hybrid merged on legs 1–2, LCD mock sim
route_solve_get_hybrid_optimize_three_hops — GET hybrid_optimize=true on 3-hop path

Docs / agent playbooks

Updated docs/testing.md, docs/indexer-invariants.md, docs/contracts-security-audit.md (L8 row), TEST_GAP_MATRIX.md
New skills/AGENTS_TESTING_MULTIHOP_HYBRID.md

Merged to main in commit b34d54e.

@brouie — please verify when you have a moment. Leaving this issue open until sign-off.

Verification checklist

cd smartcontracts && cargo test router_three_hop_two_legs_hybrid_matches_simulate
cd smartcontracts && cargo test router_two_hop_first_leg_hybrid_matches_simulate
cd indexer && cargo test --test api_route_solve three_hop -j 1 -- --test-threads=1 (Postgres + migrations)
Confirm docs/testing.md and L8 row in docs/contracts-security-audit.md reference #192 tests
Skim skills/AGENTS_TESTING_MULTIHOP_HYBRID.md for agent onboarding accuracy
Optional: LocalTerra 3-hop hybrid swap smoke after deploy-dex-local.sh

Verification sign-off (agent)

Verified GitLab #192 on main @ 0e5f020 using worktree fix/issue-192-verify.

Acceptance criteria

Contract integration: cargo test hybrid_matches_simulate — both router_two_hop_first_leg_hybrid_matches_simulate and router_three_hop_two_legs_hybrid_matches_simulate pass (L8 sim vs execute parity, ≥2 book fills on 3-hop path).
Indexer fixtures: cargo test --test api_route_solve three_hop -j 1 -- --test-threads=1 — route_solve_post_three_hop_multi_leg_hybrid and route_solve_get_hybrid_optimize_three_hops pass (Postgres dex_indexer_test, Wiremock LCD).
Docs: docs/testing.md L8/hybrid section, docs/contracts-security-audit.md L8 row, and skills/AGENTS_TESTING_MULTIHOP_HYBRID.md all reference #192 tests accurately.

Verification checklist

Contract tests (both hybrid multihop cases)
Indexer three_hop integration tests (re-run after merging latest main)
Doc cross-links confirmed
Agent playbook skimmed — commands and file paths match repo
Optional smoke: LocalTerra stack healthy; indexer finds 3-hop path ONYX→SLATE via pool_only=true; browser MCP confirmed Swap UI loads with connected wallet and token picker on :5173. Default hybrid GET for that pair returns 400 router sim on current local book state (expected when optimizer splits don’t sim cleanly on live chain) — not a regression in #192 test coverage.

No code changes required; closing as verified.
