From 6d4caf4ef55f9c164051dbd26b521d2718b707bb Mon Sep 17 00:00:00 2001 From: GraveYield Date: Thu, 14 May 2026 13:33:18 +0800 Subject: [PATCH] feat(grave-vault): m3 salvage_pool pre-flight + cert freshness gates (rebased) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Re-submitting PR #12's m3 work, rebased onto current main (post-m4 Scanner + post-Anchor 0.32 toolchain bump). The original PR #12 was opened on 2026-05-10 and is now 4 commits behind main; this branch supersedes it. What ships: ### Scanner — cert_ttl_seconds governance-configurable - state/protocol_config.rs: new `cert_ttl_seconds: i64` field - constants.rs: new MIN_CERT_TTL_SECONDS=600 (hardcoded floor) and DEFAULT_CERT_TTL_SECONDS=3600 (default 1h) - errors.rs: new 6019 CertTtlBelowMinimum - instructions/initialize.rs: cert_ttl_seconds param with floor validation - instructions/update_protocol_config.rs: cert_ttl_seconds Option with floor - instructions/evaluate_pool_phase2.rs: reads cfg.cert_ttl_seconds (preserves m4's adapter wiring with remaining_accounts + pool_data.lp_mint) ### Vault — salvage_pool pre-flight + 5 gates - programs/grave-vault/src/instructions/salvage_pool.rs (flagship): 1. !cfg.emergency_paused -> ProtocolPaused 2. !cert.is_expired(now) -> EligibilityCertExpired 3. cert.criteria_bitmap == 0x3F -> InvalidEligibilityCert 4. cert.amm_program_id / pool_address match params -> InvalidEligibilityCert 5. pool.key() == params.pool_address -> PreflightFailed - eligibility_cert migrated UncheckedAccount -> Account<'info, EligibilityCert> for automatic owner-program validation against grave_scanner::ID - programs/grave-vault/src/instructions/claim_lp_proceeds.rs: lp_holder_pool_vault aligned to SystemAccount<'info> for type consistency ### Anchor 0.32 migration (NEW work, not in original PR #12) Anchor 0.32 rejects `init`/`init_if_needed` on `SystemAccount` with a deliberate compile error. PR #12's design used init_if_needed for the lp_holder_pool_vault PDA; this rebase replaces it with the canonical Anchor 0.32 pattern: - lp_holder_pool_vault changes from `SystemAccount<'info>` with `init_if_needed` to `UncheckedAccount<'info>` with `mut, seeds, bump` (PDA validation only; no init constraint) - Handler issues a manual `anchor_lang::system_program::create_account` CPI when `vault.lamports() == 0` (lazy first-salvage init) - grave-vault/Cargo.toml: removed the now-unused `init-if-needed` feature - Net result identical to the original design: system-owned, space=0, rent-exempt PDA created on first salvage of each pool CHANGELOG.md introduced with v1.0.6 entry naming each change.
