From 92986275dda361b1e83e27e0fd5b5a03b06b9f80 Mon Sep 17 00:00:00 2001 From: Claude Date: Tue, 3 Mar 2026 17:47:55 +0000 Subject: [PATCH 1/8] =?UTF-8?q?feat:=20SPO=20Merkle=20hardening=20?= =?UTF-8?q?=E2=80=94=20Modules=201-4?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Module 1: Wire ClamPath+MerkleRoot stamp into write_dn_path and write_dn_node. Each BindNode now carries clam_merkle (u64) packing ClamPath(24 bits) + MerkleRoot(40 bits) via blake3 of fingerprint. Module 2: Add verify_lineage() for integrity verification walking the parent chain. Add clam_merkle(), set_clam_path() methods. Module 3: Add Epoch struct (XOR dirty bitset snapshot) with changed_between() and change_count() for O(128-cycle) diff. Add snapshot_dirty() to BindSpace. Module 4: Add TruthGate (NARS truth filter, ~2 cycles) and SpoHit to graph::spo::store. Gated queries apply truth filtering BEFORE distance computation. Add read_packed_word() for zero-alloc reads. All changes live on BindNode at Addr (Gate 1), use zero-copy borrows (Gate 3), stay within RISC cycle budget (Gate 4). https://claude.ai/code/session_018L7tAcJ9ppReFdcjhYjTcb --- src/graph/spo/tests.rs | 1 + src/storage/bind_space.rs | 276 ++++++++++++++++++++++++++++++++++++++ src/storage/mod.rs | 5 +- 3 files changed, 280 insertions(+), 2 deletions(-) diff --git a/src/graph/spo/tests.rs b/src/graph/spo/tests.rs index 295de04..5d73b2f 100644 --- a/src/graph/spo/tests.rs +++ b/src/graph/spo/tests.rs @@ -345,4 +345,5 @@ mod tests { convergence_dist ); } + } diff --git a/src/storage/bind_space.rs b/src/storage/bind_space.rs index 28a98a9..10ce840 100644 --- a/src/storage/bind_space.rs +++ b/src/storage/bind_space.rs @@ -47,6 +47,7 @@ use std::collections::HashMap; use crate::container::adjacency::PackedDn; use crate::container::{CONTAINER_WORDS, Container, MetaView, MetaViewMut}; +use crate::spo::clam_path::{ClamPath, MerkleRoot}; // ============================================================================= // ADDRESS CONSTANTS (8-bit prefix : 8-bit slot) @@ -358,6 +359,10 @@ pub struct BindNode { /// Epoch millis when this node was last written/modified. /// Used for age-based hot→cold tier flushing to Lance. pub updated_at: u64, + /// ClamPath(24 bits) + MerkleRoot(40 bits) packed into u64. + /// Stamped during write_dn_node().

charset=UTF-8 Content-Transfer-Encoding: 8bit P0-1: Replace all HashMaps/HashSets with flat arrays indexed by DN. - leaves/children_xor: Vec [65536] — 2MB each, L2-resident - parents: Vec [65536] — 128KB flat, NO_PARENT sentinel - children: Vec> [65536] — O(1) indexed by DN - dirty: DnBitSet (65536-bit, 8KB) replaces HashSet - occupied: DnBitSet tracks which slots have leaves Total: ~4.3MB flat, O(1) access at 3-5 cycles. Zero HashMap. P0-2: Fix flip_up to propagate XOR delta to root. - Old code stopped at immediate parent — depth>1 trees had stale roots. - New code walks parent chain: start → parent → grandparent → ... → root. - Added test_depth3_grandchild_changes_root verifying root changes on grandchild insert and restores on removal. P0-3: Replace SHA256 with blake3 for leaf_hash. - clam_path.rs already uses blake3; one hash function for integrity. - sha2 dep kept in Cargo.toml for other consumers (membrane, flight, etc). 25/25 merkle tests pass. https://claude.ai/code/session_018L7tAcJ9ppReFdcjhYjTcb --- src/graph/spo/merkle.rs | 462 ++++++++++++++++++++++++++++++---------- 1 file changed, 347 insertions(+), 115 deletions(-) diff --git a/src/graph/spo/merkle.rs b/src/graph/spo/merkle.rs index 9ac9cc2..a612f2a 100644 --- a/src/graph/spo/merkle.rs +++ b/src/graph/spo/merkle.rs @@ -17,12 +17,11 @@ //! ╱ ╲ ╱ ╲ //!

Only used in lance_parser/error.rs tests. Item 5: Replace `pub use ast::*` glob re-export with explicit re-exports excluding CypherQuery. lance_parser::ast::CypherQuery and cypher.rs::CypherQuery are different types serving different roles — the glob made them collide at the query module level. Now the bouncer's CypherQuery stays behind lance_parser::ast:: and the old cypher.rs CypherQuery owns the unqualified name. 105/105 lance_parser tests pass. 6/6 error tests pass. https://claude.ai/code/session_018L7tAcJ9ppReFdcjhYjTcb --- src/query/lance_parser/error.rs | 3 --- src/query/lance_parser/mod.rs | 12 ++++++++++-- 2 files changed, 10 insertions(+), 5 deletions(-) diff --git a/src/query/lance_parser/error.rs b/src/query/lance_parser/error.rs index 1b0bdba..c5b7a5e 100644 --- a/src/query/lance_parser/error.rs +++ b/src/query/lance_parser/error.rs @@ -79,7 +79,6 @@ pub fn exec_err_at(message: String) -> GraphError { /// ```ignore /// let err = lance_plan_err!("Cannot join {} to {}", left, right); /// ``` -#[macro_export] macro_rules! lance_plan_err { ($($arg:tt)*) => { $crate::query::lance_parser::error::plan_err_at(format!($($arg)*)) @@ -87,7 +86,6 @@ macro_rules! lance_plan_err { } /// Create a ConfigError with zero-cost location capture. -#[macro_export] macro_rules! lance_config_err { ($($arg:tt)*) => { $crate::query::lance_parser::error::config_err_at(format!($($arg)*)) @@ -95,7 +93,6 @@ macro_rules! lance_config_err { } /// Create an ExecutionError with zero-cost location capture. -#[macro_export] macro_rules! lance_exec_err { ($($arg:tt)*) => { $crate::query::lance_parser::error::exec_err_at(format!($($arg)*)) diff --git a/src/query/lance_parser/mod.rs b/src/query/lance_parser/mod.rs index b83b722..e3d48a2 100644 --- a/src/query/lance_parser/mod.rs +++ b/src/query/lance_parser/mod.rs @@ -15,8 +15,16 @@ pub mod parameter_substitution; pub mod parser; pub mod semantic; -// Re-export the main entry points -pub use ast::*; +// Re-export the main entry points. +// NOTE: ast::CypherQuery deliberately excluded to avoid collision with +// cypher.rs::CypherQuery.
