From ed7df5e746746d24a63e0003cc30388c08df54f6 Mon Sep 17 00:00:00 2001 From: GraveYield Date: Sat, 16 May 2026 13:54:24 +0800 Subject: [PATCH 1/5] feat(m6): claim_lp_proceeds Merkle verification + SOL transfer MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Wires the second half of the salvage settlement flow: original LP holders prove inclusion in the snapshot recorded by salvage_pool and withdraw their pro-rata share from lp_holder_pool_vault. New `merkle.rs` module implements SHA-256 sorted-pair verification (OpenZeppelin / Uniswap convention) with 7 host unit tests covering single-leaf, two-leaf, four-leaf trees, sort invariance, empty proofs, and tampering. claim_lp_proceeds handler replaces m3's two TODOs: - Merkle proof check (was `!proof.is_empty()` stub) - SOL transfer from lp_holder_pool_vault to lp_holder (was TODO comment) PR scope per Option B (2 PRs by code path): this is the claim_lp_proceeds side. The matching salvage_pool execution path (Raydium V4 + Jupiter + 40/40/20 distribution) is PR #19. The two PRs have NO file overlap — m5 touches instructions/salvage_pool.rs and cpi/, m6 touches instructions/claim_lp_proceeds.rs and merkle.rs. Both modify lib.rs in different sections so the rebase-at-merge is clean. No new error codes — InvalidClaimProof (7010) and ClaimAlreadyProcessed (7011) already cover the m6 surface.

The only change here is the CI workflow step. If PR #19 lands first with the same ci.yml change, this PR's rebase resolves trivially (identical content). If PR #20 lands first, PR #19 rebases against this.

Error: Building IDL failed. Anchor 0.32.1's `anchor idl build` still invokes rustup to install a nightly toolchain, which the workflow's `dtolnay/rust-toolchain@stable` step doesn't pre-install. The CI runner can reach static.rust-lang.org in principle, but rustup's auto-install path needs an explicit toolchain declared. Fix: pass `--no-idl` to skip IDL generation. The on-chain program builds and verifies correctly without IDL; IDL is only required for TypeScript client type generation, which is a separate workstream (can land later as a CI step that installs nightly before invoking `anchor idl build`).

This is the same silent-no-op pattern I have in failure-pattern memory; I had closed PR #18 thinking cargo-binstall was working (based on PR #17's intermittent success), but it's actually flaky/broken for 0.32.x consistently. Fix: replace cargo binstall with `cargo install --locked --version 0.32.1 anchor-cli` + an `anchor --version` assertion. Source compile takes ~5-7 min on a cold cache but is cached by Swatinem/rust-cache@v2, so steady-state CI time is unchanged. The version assertion fails the install step itself on any future regression instead of deferring to the build step where the symptom is opaque (0s install + 1s build failure is harder to diagnose than a clean install-step failure). Combined with fixup #2 (platform-tools v1.54) and fixup #3 (--no-idl to skip nightly-Rust IDL generation), this should clear anchor build. Locally verified all three together produce a clean `anchor build --no-idl` in 5.67s on m5 and 5.02s on m6.
