feat(proofs): add bounded historical proof history - #142
Conversation
validate_payload already registered an expectation in convert_payload_to_block; clearing it on the early L1-index reject path matches the inner-failure cleanup and avoids a stale cache entry until LRU eviction.
Format the L1-index cleanup path, upgrade crossbeam-epoch to 0.9.20, and drop advisory ignores that no longer match after the reth main bump.

How do review limits work?CodeRabbit enforces per-developer PR review limits for each organization. Most developers receive the normal plan review availability. For paid Pro and Pro+ PR reviews, CodeRabbit uses adaptive limits for sustained high-volume activity. When a developer's recent PR review activity reaches the 95th percentile or higher among CodeRabbit users, additional reviews become available more gradually as earlier reviews age out of the rolling window.

This exports 604_800 and documents a seven-day, one-second-based window, while the PR objective requires a default of 1_296_000 blocks. If downstream startup/CLI wiring uses this constant, nodes will prune history earlier than promised.

The previous proof-history test only proved RPC wiring: it mined one empty block and checked that `eth_getProof` for the zero address returned the same response on the normal and auth ports. It could not tell a correct historical proof from a latest-state proof. Node e2e (crates/node/tests/it/proof_history.rs): - Deploy an SSTORE setter and mutate state across blocks, then query each height and assert the value that block actually held. - Verify every successful proof against that block's canonical stateRoot via `AccountProof::verify`, which also checks storage proofs against the account storage root. Assert a proof does not verify against a different block's root. - Drive the fork case purely through a reorg instead of poking `unwind_history` first, so a broken ExEx reorg path can no longer pass. The height is unchanged across the reorg, so wait on the exact (number, hash). - Read requested slots by key and panic on a missing entry. Defaulting to zero let a response carrying no storage proof pass an `== 0` assertion. Add a multi-slot case including an unset slot with its exclusion proof. - Tighten the future-block assertion to the window error; numeric block ids resolve without an existence check, so the window bounds reject them. - Add a canonical-block-hash lookup alongside the height lookup. - Rename `survives_node_restart_and_continues` to `db_survives_node_restart`: it never appended after the restart. Assert per-block change sets survive the reopen, since pointers alone would outlive lost rows. This also pins that the earliest block is a baseline snapshot rather than a diff. - Rename the verification-interval test to reflect that it asserts correctness on that path, not that the interval selects it. ExEx unit tests (crates/proofs-exex/src/lib.rs): - Cover `build_batch_entry` directly, asserting the chosen `BatchBlock` variant for interval 0/1/N on and off the interval, with and without cached data. Stubbing `should_verify` to false turns two of these red, whereas the e2e stayed green because the cached path also yields correct proofs. - Add an `ensure_initialized` case for a latest hash that is not canonical, the shape of a proofs DB restored beside a mismatched chain snapshot. - Assert error messages in the existing `ensure_initialized` failure cases; the prune-threshold fixture also trips the later canonical-hash check, so a bare `expect_err` did not identify which guard fired.

Outside diff comments:
In `@crates/proofs-exex/src/lib.rs`:
- Around line 696-713: Update hash_for_num to encode the full u64 block number
into the hash using the existing 8-byte representation instead of truncating to
u8. Update mk_block to derive the parent hash from a saturating predecessor so
block 0 uses hash_for_num(0) without underflow.
- Around line 394-457: Update sync_forward so storage lookup, batch preparation,
and execute_and_store_batch failures re-arm sync_target with the unprocessed
target range before retrying instead of returning with work lost. Add a short
async backoff before retrying to prevent persistent errors from spinning, while
preserving the existing pending-state and successful batch behavior; anchor the
changes in sync_forward and its interaction with sync_target.

Forward-sync now re-arms after transient errors instead of waiting forever for the next notification. Tests read account nonces from state so CodeQL no longer flags them as hardcoded cryptographic IVs.

Summary
eth_getProofrequests on both normal and authenticated RPCproofs init,proofs prune, andproofs unwindoperator commandsThe versioned-trie implementation is adapted from Base commit
b2673bbd927cb34d7cfad4d448bfbd5bd30eae88under MIT; Morph owns the integration,MDBX backend, lifecycle, RPC policy, and tests.

This PR does not add a reference-index disable flag, reference-index status RPC,
snapshot format, compatibility migration, or benchmark harness. Live long-running
network sync, Hive/geth datasets, and performance benchmarks remain separate validation work.
