From d9124e0bde9e152f4cdcca8d480e0e60839e627c Mon Sep 17 00:00:00 2001 From: Dylon Edwards Date: Fri, 27 Mar 2026 16:44:18 -0400 Subject: [PATCH 01/17] fix: resolve observer COST_MISMATCH during block replay MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit - Revert ReplayRSpace rig() to Scala dual-indexing: index each COMM under all its IOEvents (consume + all produces), not just the triggering one, so COMMs are findable from either side during replay - Change reducer eval_par term ordering to receives-first: consumes store continuations and register joins before produces try to match, preventing COMM_MATCH_FAIL cascades from missing continuations - Fix Produce equality in ReplayRSpace matches() and was_repeated_enough_times() to compare by hash only, matching Scala's Produce.equals() override — Rust-only fields (is_deterministic, output_value, failed) are not part of the hash and caused false negatives in comm.produces.contains() checks - Fix hot_store to_map() to include channels with only continuations (no data), which were previously excluded from the iteration - Remove broken workarounds that masked the root cause: deferred produces, fallback produce matching, put_join/remove_join simulation in locked_consume COMM path - Add per-bind peek support in eval_receive (BTreeSet peeks instead of single bool), matching Scala's per-channel peek semantics - Add comprehensive replay diagnostics gated behind tracing targets: COMM trigger-side mismatch detection, COST_TRACE_OP with channel hashes and eval nesting depth, COMM_MATCH_FAIL detailed state dumps, hot store per-channel mutation trace, checkpoint state hashing, validator produce/consume instrumentation - Update cost_accounting_spec expected values for persistent produce contracts affected by receives-first evaluation order - Update reduce_spec tests to use structural assertions instead of exact random_state byte comparison (bytes depend on eval ordering) - Add exploratory deploy API tests --- .cargo/config.toml | 11 +- Cargo.lock | 18 +- .../rust/dag/block_dag_key_value_storage.rs | 10 +- casper/src/rust/api/block_api.rs | 33 +- .../rust/engine/block_approver_protocol.rs | 8 +- casper/src/rust/engine/initializing.rs | 5 +- casper/src/rust/rholang/replay_runtime.rs | 17 + casper/src/rust/rholang/runtime.rs | 339 +++++++- .../src/rust/util/rholang/interpreter_util.rs | 48 +- .../src/rust/util/rholang/runtime_manager.rs | 103 ++- .../tests/api/exploratory_deploy_api_test.rs | 138 +++ .../block_creator_memory_profile_spec.rs | 3 +- ...pute_parents_post_state_regression_spec.rs | 3 + casper/tests/engine/initializing_spec.rs | 2 +- casper/tests/genesis/contracts/pos_spec.rs | 2 +- .../genesis/contracts/tree_hash_map_spec.rs | 2 +- casper/tests/util/rholang/deploy_id_test.rs | 3 +- casper/tests/util/rholang/deployer_id_test.rs | 6 +- .../util/rholang/runtime_manager_test.rs | 14 +- casper/tests/util/rholang/runtime_spec.rs | 12 +- models/build.rs | 10 + models/src/main/protobuf/RhoTypes.proto | 1 + models/src/rust/mod.rs | 1 + .../rholang/sorter/receive_sort_matcher.rs | 1 + models/src/rust/serde_helpers.rs | 15 + models/src/rust/test_utils/test_utils.rs | 1 + models/tests/par_sort_matcher_test.rs | 12 + node/src/rust/api/web_api.rs | 34 + node/src/rust/web/shared_handlers.rs | 16 + node/src/rust/web/web_api_routes.rs | 1 + node/src/rust/web/web_api_routes_v1.rs | 1 + .../processes/p_contr_normalizer.rs | 3 + .../processes/p_input_normalizer.rs | 25 +- .../processes/p_match_normalizer.rs | 2 + .../processes/p_var_ref_normalizer.rs | 1 + .../compiler/receive_binds_sort_matcher.rs | 15 +- rholang/src/rust/interpreter/contract_call.rs | 11 +- rholang/src/rust/interpreter/dispatch.rs | 29 + rholang/src/rust/interpreter/interpreter.rs | 79 ++ .../rust/interpreter/matcher/fold_match.rs | 50 +- rholang/src/rust/interpreter/matcher/match.rs | 121 ++- rholang/src/rust/interpreter/reduce.rs | 677 ++++++++++++--- .../registry/registry_bootstrap.rs | 1 + .../interpreter/storage/charging_rspace.rs | 178 +++- .../interpreter/storage/storage_printer.rs | 1 + rholang/src/rust/interpreter/substitute.rs | 2 + .../src/rust/interpreter/system_processes.rs | 95 +- .../tests/accounting/cost_accounting_spec.rs | 22 +- rholang/tests/matcher/match_test.rs | 6 + rholang/tests/reduce_spec.rs | 113 +-- rspace++/Cargo.toml | 3 +- .../src/rspace/history/history_repository.rs | 2 +- .../rspace/history/history_repository_impl.rs | 53 +- .../instances/rspace_history_reader_impl.rs | 30 +- rspace++/src/rspace/hot_store.rs | 502 ++++++++++- rspace++/src/rspace/internal.rs | 96 ++- rspace++/src/rspace/replay_rspace.rs | 434 ++++++++-- rspace++/src/rspace/reporting_rspace.rs | 8 + rspace++/src/rspace/rspace.rs | 648 +++++++++++++- rspace++/src/rspace/rspace_interface.rs | 8 + rspace++/src/rspace/space_matcher.rs | 54 +- rspace++/src/rspace/state/rspace_exporter.rs | 12 + rspace++/src/rspace/state/rspace_importer.rs | 10 + rspace++/src/rspace/trace/event.rs | 2 +- rspace++/tests/hot_store_spec.rs | 12 +- rspace++/tests/replay_rspace_tests.rs | 99 +-- rspace++/tests/storage_actions_test.rs | 809 +++++++++++++++++- 67 files changed, 4395 insertions(+), 688 deletions(-) create mode 100644 models/src/rust/serde_helpers.rs diff --git a/.cargo/config.toml b/.cargo/config.toml index 5af6dc2ed..98dd4ab22 100644 --- a/.cargo/config.toml +++ b/.cargo/config.toml @@ -3,13 +3,16 @@ # This file contains build configuration and compiler flags for the entire workspace.

Bug fixes: - Treat UnknownRootError as invalid block (Right(None)) instead of internal error (Left) by adding InvalidPreStateHash replay failure variant — blocks referencing non-existent state roots are invalid, not errored, and retrying is pointless - Update hardcoded expected hash in runtime_spec to match receives-first evaluation ordering Test coverage for d9124e0b gaps: - Receives-first COMM ordering: validates COMM fires correctly when send and receive coexist in a single Par - Genesis pre-state hash replay: verifies replay_compute_state succeeds using the block's own pre_state_hash (not a hardcoded constant) - spawn_runtime_at consistency: confirms data written by a deploy is readable via spawn_runtime_at at the new state but not at the old - Mixed peek multi-bind: validates per-bind peek preserves peeked channel data while consuming non-peeked channel data - locally_free clearing: verifies COMM fires despite stale locally_free bits on substituted channels inside new blocks Infrastructure: - Add macOS LMDB semaphore cleanup to prevent ENOSPC after repeated test runs (atexit handler unlinks orphaned /MDB{r,w} semaphores) --- Cargo.lock | 1 + casper/Cargo.toml | 1 + .../src/rust/util/rholang/interpreter_util.rs | 34 ++- .../src/rust/util/rholang/replay_failure.rs | 11 + casper/tests/util/rholang/resources.rs | 183 ++++++++++++ .../util/rholang/runtime_manager_test.rs | 127 ++++++++ casper/tests/util/rholang/runtime_spec.rs | 2 +- rholang/tests/reduce_spec.rs | 273 ++++++++++++++++++ 8 files changed, 630 insertions(+), 2 deletions(-) diff --git a/Cargo.lock b/Cargo.lock index fbedc3b53..68edd2af4 100644 --- a/Cargo.lock +++ b/Cargo.lock @@ -628,6 +628,7 @@ dependencies = [ "itertools 0.14.0", "k256", "lazy_static", + "libc", "lz4_flex", "metrics 0.23.1", "metrics-util 0.17.0", diff --git a/casper/Cargo.toml b/casper/Cargo.toml index ba58a0fba..789bd17c1 100644 --- a/casper/Cargo.toml +++ b/casper/Cargo.toml @@ -52,6 +52,7 @@ k256 = { version = "0.13.4", features = ["ecdsa"] } serial_test = "3.1" env_logger = "0.11.8" tempfile = "3.24.0" +libc = "0.2" diff --git a/casper/src/rust/util/rholang/interpreter_util.rs b/casper/src/rust/util/rholang/interpreter_util.rs index 0df854940..ae67c0c4f 100644 --- a/casper/src/rust/util/rholang/interpreter_util.rs +++ b/casper/src/rust/util/rholang/interpreter_util.rs @@ -25,7 +25,11 @@ use models::{ use rholang::rust::interpreter::{ compiler::compiler::Compiler, errors::InterpreterError, system_processes::BlockData, }; -use rspace_plus_plus::rspace::{hashing::blake2b256_hash::Blake2b256Hash, history::Either}; +use rspace_plus_plus::rspace::{ + errors::{HistoryError, RSpaceError, RootError}, + hashing::blake2b256_hash::Blake2b256Hash, + history::Either, +}; use crate::rust::{ block_status::BlockStatus, @@ -238,6 +242,15 @@ pub async fn validate_block_checkpoint( } } +fn extract_unknown_root_error(err: &CasperError) -> Option<&str> { + match err { + CasperError::InterpreterError(InterpreterError::RSpaceError( + RSpaceError::HistoryError(HistoryError::RootError(RootError::UnknownRootError(msg))), + )) => Some(msg.as_str()), + _ => None, + } +} + async fn replay_block( initial_state_hash: StateHash, block: &BlockMessage, @@ -383,6 +396,20 @@ async fn replay_block( } } Err(replay_error) => { + // UnknownRootError means the block claims a pre-state hash that + // doesn't exist in the roots store.

The old implementation had a TOCTOU bug: it locked, read, deducted, unlocked, re-locked, and checked — two concurrent branches could both deduct past zero between the two lock acquisitions. The CAS loop atomically checks remaining budget and deducts in a single compare_exchange_weak, eliminating the race window. This is a prerequisite for concurrent Par evaluation (Phase 6) where multiple futures charge costs simultaneously. Also normalizes consume-triggered COMM cost accounting to produce- triggered semantics in charging_rspace.rs, ensuring gas costs are deterministic regardless of which side fires a COMM. This makes the total cost order-independent (commutative) for concurrent evaluation. Phase 1 of 6: Maximally parallel RSpace via lock removal and interior mutability. Next: remove hot store outer Mutex (Phase 2). --- .../src/rust/interpreter/accounting/mod.rs | 101 +++++++----------- rholang/src/rust/interpreter/reduce.rs | 22 ++-- .../interpreter/storage/charging_rspace.rs | 25 ++++- 3 files changed, 72 insertions(+), 76 deletions(-) diff --git a/rholang/src/rust/interpreter/accounting/mod.rs b/rholang/src/rust/interpreter/accounting/mod.rs index e69495d43..e4d66e044 100644 --- a/rholang/src/rust/interpreter/accounting/mod.rs +++ b/rholang/src/rust/interpreter/accounting/mod.rs @@ -1,12 +1,12 @@ use std::{ collections::VecDeque, - sync::{Arc, Mutex}, + sync::{ + atomic::{AtomicI64, Ordering}, + Arc, Mutex, + }, }; use costs::Cost; -use shared::rust::{ - metrics_constants::COST_ACCOUNTING_METRICS_SOURCE, metrics_semaphore::MetricsSemaphore, -}; use super::errors::InterpreterError; @@ -20,8 +20,7 @@ pub type _cost = CostManager; #[derive(Clone)] pub struct CostManager { - state: Arc>, - semaphore: Arc, + value: Arc, log: Arc>>, max_log_entries: usize, } @@ -38,7 +37,7 @@ impl CostManager { .unwrap_or(0) } - pub fn new(initial_value: Cost, semaphore_count: usize) -> Self { + pub fn new(initial_value: Cost, _semaphore_count: usize) -> Self { let max_log_entries = Self::resolve_max_log_entries(); let initial_capacity = if max_log_entries == 0 { 0 @@ -49,79 +48,59 @@ impl CostManager { }; Self { - state: Arc::new(Mutex::new(initial_value)), - semaphore: Arc::new(MetricsSemaphore::new( - semaphore_count, - COST_ACCOUNTING_METRICS_SOURCE, - )), + value: Arc::new(AtomicI64::new(initial_value.value)), log: Arc::new(Mutex::new(VecDeque::with_capacity(initial_capacity))), max_log_entries, } } pub fn charge(&self, amount: Cost) -> Result<(), InterpreterError> { - let permit = self.semaphore.try_acquire(); - // Scala: if (permit == None) throw SetupError - if permit.is_none() { - return Err(InterpreterError::SetupError( - "Failed to acquire semaphore".to_string(), - )); - } - let permit = permit.unwrap(); - - let mut current_cost = self - .state - .try_lock() - .map_err(|_| InterpreterError::SetupError("Failed to lock cost state".to_string()))?; - - // Scala: if (c.value < 0) error.raiseError[Unit](OutOfPhlogistonsError) - if current_cost.value < 0 { - return Err(InterpreterError::OutOfPhlogistonsError); - } - - // Scala: cost.set(c - amount) - current_cost.value -= amount.value; - if self.max_log_entries > 0 { - let mut log = self.log.lock().unwrap(); - if log.len() >= self.max_log_entries { - let _ = log.pop_front(); + loop { + let current = self.value.load(Ordering::Acquire); + if current < 0 { + return Err(InterpreterError::OutOfPhlogistonsError); + } + let new_value = current - amount.value; + match self.value.compare_exchange_weak( + current, + new_value, + Ordering::AcqRel, + Ordering::Acquire, + ) { + Ok(_) => { + if self.max_log_entries > 0 { + let mut log = self.log.lock().expect("cost log lock poisoned"); + if log.len() >= self.max_log_entries { + let _ = log.pop_front(); + } + log.push_back(amount); + } + if new_value < 0 { + return Err(InterpreterError::OutOfPhlogistonsError); + } + return Ok(()); + } + Err(_) => continue, } - log.push_back(amount); - } - drop(permit); - drop(current_cost); - - // Scala has TWO checks: - // 1.

This defeated DashMap's per-shard read-write locks which already provide thread-safe concurrent access. Changes: - Remove Mutex wrapper from InMemHotStore - Remove Mutex wrapper (also uses DashMaps) - Access DashMaps directly via self.state.data.get() etc. - Use DashMap::clear() for clear() instead of field reassignment - Update tests to access state directly without lock().unwrap() The HotStore trait already used &self (not &mut self), so no trait changes were needed. All 294 rspace++ tests pass. Phase 2 of 6: Maximally parallel RSpace via lock removal and interior mutability. Next: ISpace trait &self + interior mutability (Phase 3). --- rspace++/src/rspace/hot_store.rs | 229 ++++++++++----------------- rspace++/src/rspace/replay_rspace.rs | 2 +- rspace++/src/rspace/rspace.rs | 2 +- rspace++/tests/hot_store_spec.rs | 218 +++++++++++-------------- 4 files changed, 178 insertions(+), 273 deletions(-) diff --git a/rspace++/src/rspace/hot_store.rs b/rspace++/src/rspace/hot_store.rs index 449f4a358..9a2742f59 100644 --- a/rspace++/src/rspace/hot_store.rs +++ b/rspace++/src/rspace/hot_store.rs @@ -2,7 +2,7 @@ use std::collections::HashMap;

Interior mutability changes in RSpace and ReplayRSpace: - event_log: Vec → Arc>> - produce_counter: BTreeMap → Arc> - history_repository: Arc> → Arc>>> - store: Arc> → Arc>>> Added get_store() and get_history_repository() helper methods for lock-free read access to the inner Arc clones. Updated all callers across rspace++, rholang, and casper crates. All 294 rspace++ tests and 39 casper rholang tests pass. Phase 3 of 6: Maximally parallel RSpace via lock removal and interior mutability. Next: per-channel-group locks for joins (Phase 4). --- .../src/rust/util/rholang/runtime_manager.rs | 2 +- .../interpreter/storage/charging_rspace.rs | 24 +- .../rust/interpreter/test_utils/resources.rs | 2 +- .../tests/accounting/cost_accounting_spec.rs | 2 +- rspace++/libs/rspace_rhotypes/src/lib.rs | 36 +-- rspace++/src/rspace/replay_rspace.rs | 222 +++++++------- rspace++/src/rspace/reporting_rspace.rs | 40 +-- rspace++/src/rspace/rspace.rs | 231 +++++++------- rspace++/src/rspace/rspace_interface.rs | 24 +- rspace++/tests/export_import_tests.rs | 2 +- rspace++/tests/replay_rspace_tests.rs | 20 +- rspace++/tests/storage_actions_test.rs | 282 +++++++++--------- 12 files changed, 467 insertions(+), 420 deletions(-) diff --git a/casper/src/rust/util/rholang/runtime_manager.rs b/casper/src/rust/util/rholang/runtime_manager.rs index 110cf9518..bcddf2ab8 100644 --- a/casper/src/rust/util/rholang/runtime_manager.rs +++ b/casper/src/rust/util/rholang/runtime_manager.rs @@ -1202,7 +1202,7 @@ impl RuntimeManager { RSpace::create_with_replay(store, Arc::new(Box::new(Matcher))) .expect("Failed to create RSpaceWithReplay");

Ok(()) From 550132d72ef50a20ae96f5be3c42f1bc212a5dd3 Mon Sep 17 00:00:00 2001 From: Dylon Edwards Date: Wed, 1 Apr 2026 18:19:07 -0400 Subject: [PATCH 09/17] refactor: per-channel-group locks for join pattern atomicity (Phase 4) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Replace the global Mutex on the RSpace store with fine-grained per-channel-group locks. Each channel group (determined by the join pattern) gets its own Mutex, keyed by a sorted hash of the channels. Changes to RSpace and ReplayRSpace: - store: Arc>>> → Arc>>> (RwLock allows concurrent reads; write only during checkpoint/reset) - history_repository: same Mutex → RwLock change - New channel_locks: DashMap>> for per-group locking - locked_produce: acquires per-group lock for each join group iteration - locked_consume: acquires per-group lock for the consume's channel set - Deadlock prevention via sorted channel hash ordering For channels WITHOUT joins (the vast majority — private unforgeable names used by single send/receive pairs), the per-group lock has minimal contention. Only multi-channel join patterns serialize. All 294 rspace++ tests and 20 casper runtime tests pass. Phase 4 of 6: Maximally parallel RSpace via lock removal and interior mutability. Next: remove interpreter-level space lock (Phase 5). --- rspace++/src/rspace/replay_rspace.rs | 107 +++++++++++----- rspace++/src/rspace/rspace.rs | 182 +++++++++++++++++++++++---- 2 files changed, 236 insertions(+), 53 deletions(-) diff --git a/rspace++/src/rspace/replay_rspace.rs b/rspace++/src/rspace/replay_rspace.rs index cb654b2c4..8426686a6 100644 --- a/rspace++/src/rspace/replay_rspace.rs +++ b/rspace++/src/rspace/replay_rspace.rs @@ -6,10 +6,11 @@ // This matches Scala's Span[F].traceI() semantics for async operations. use std::collections::{BTreeMap, BTreeSet, HashMap, HashSet}; +use std::collections::hash_map::DefaultHasher; use std::fmt::Debug; -use std::hash::Hash; +use std::hash::{Hash, Hasher}; use std::sync::atomic::{AtomicI64, Ordering}; -use std::sync::{Arc, Mutex}; +use std::sync::{Arc, Mutex, RwLock}; use dashmap::DashMap; use rand::seq::SliceRandom; @@ -41,14 +42,15 @@ use crate::rspace::history::history_repository::HistoryRepository; use crate::rspace::hot_store::{HotStore, HotStoreInstances}; use crate::rspace::hot_store_action::{DeleteAction, HotStoreAction, InsertAction}; use crate::rspace::internal::*; +use crate::rspace::rspace::ChannelGroupGuard; use crate::rspace::space_matcher::SpaceMatcher; #[repr(C)] #[derive(Clone)] pub struct ReplayRSpace { - pub history_repository: Arc + Send + Sync + 'static>>>>, - pub store: Arc>>>>, + pub history_repository: Arc + Send + Sync + 'static>>>>, + pub store: Arc>>>>, installs: Arc, Install>>>, event_log: Arc>, produce_counter: Arc>>, @@ -57,6 +59,7 @@ pub struct ReplayRSpace { pub replay_data: MultisetMultiMap, logger: Arc>>>, replay_waiting_continuations_estimate: Arc, + channel_locks: Arc>>>, } impl SpaceMatcher for ReplayRSpace @@ -195,16 +198,16 @@ where let next_history = { - let hr = self.history_repository.lock().expect("history_repository lock in create_checkpoint"); + let hr = self.history_repository.read().expect("history_repository read lock in create_checkpoint"); hr.checkpoint(changes) }; { - let mut hr = self.history_repository.lock().expect("history_repository lock in create_checkpoint (set)"); + let mut hr = self.history_repository.write().expect("history_repository write lock in create_checkpoint (set)"); *hr = Arc::new(next_history); } let history_reader = { - let hr = self.history_repository.lock().expect("history_repository lock in create_checkpoint (reader)"); + let hr = self.history_repository.read().expect("history_repository read lock in create_checkpoint (reader)"); hr.get_history_reader(&hr.root())?

Since ISpace methods now use &self (Phase 3) and per-channel-group locks handle concurrency (Phase 4), the global interpreter Mutex is redundant. Changes: - RhoISpace: Arc>> → Arc> - Remove 19 .try_lock().unwrap() call sites across reduce.rs, rho_runtime.rs, contract_call.rs, interpreter.rs, and lib.rs - Access self.space methods directly via &self - Remove corresponding drop(space_locked) calls The ISpace is now accessed without ANY global lock. Concurrent produce/consume operations on independent channels no longer serialize. All 115 rholang tests and 20 casper runtime tests pass.

charset=UTF-8 Content-Transfer-Encoding: 8bit Three changes that complete the concurrent evaluation architecture: 1. Content-hash candidate ordering: Replace thread_rng() shuffle in RSpace/ReplayRSpace with deterministic sorting by source.hash (Blake2b256Hash). Cryptographic hashes are uniformly distributed (fair, no starvation) while being deterministic (same data → same order). Required for consensus — random shuffle caused different COMMs on different runs. 2. FuturesUnordered in eval_inner: Replace sequential for-loop with concurrent FuturesUnordered. Receives are listed first in the terms vector to bias early continuation registration. Per-channel-group locks (Phase 4) ensure join atomicity. 3. Two-phase dispatch: Solve body evaluation interleaving that caused -644 COST_MISMATCH between RSpace (play) and ReplayRSpace (replay). Phase 1: produce/consume run concurrently, COMM body dispatch is DEFERRED to a shared queue. Phase 2: after all Phase 1 futures complete, deferred bodies dispatch sequentially. Nested eval calls create their own Phase 1/Phase 2 cycle. Also: - Fix non-deterministic DashMap iteration in replay_rspace produce lookup (use .get() instead of .clone().into_iter().find()) - Add with_isolated_runtime_manager for LMDB state isolation Results (full util::rholang suite, 5 consecutive runs): - Sequential for-loop: 3/3 pass (no concurrency) - FuturesUnordered (no defer): 2/5 pass (body interleaving → -644) - FuturesUnordered + 2-phase: 5/5 pass (concurrent + deterministic) Phase 6 of 6: Maximally parallel RSpace via lock removal and interior mutability. All phases complete. --- casper/tests/util/rholang/resources.rs | 24 ++ .../util/rholang/runtime_manager_test.rs | 7 +- rholang/src/rust/interpreter/reduce.rs | 225 ++++++++++++++---- rholang/src/rust/interpreter/rho_runtime.rs | 1 + rspace++/src/rspace/replay_rspace.rs | 26 +- rspace++/src/rspace/rspace.rs | 29 ++- 6 files changed, 243 insertions(+), 69 deletions(-) diff --git a/casper/tests/util/rholang/resources.rs b/casper/tests/util/rholang/resources.rs index 2fc3de274..a9c27c84a 100644 --- a/casper/tests/util/rholang/resources.rs +++ b/casper/tests/util/rholang/resources.rs @@ -300,6 +300,30 @@ where Ok(f(runtime_manager, genesis_context, genesis_block).await) } +/// Like `with_runtime_manager` but builds a FRESH genesis context with a +/// unique `rspace_scope_id` for complete test isolation.

Two bodies whose substituted channel sets are completely disjoint cannot interfere through the RSpace, regardless of whether those channels are unforgeable or public. + +**Dynamic channel flow.** Static analysis has a limitation: a body can create new channels at runtime and pass existing channels through them: + +```rholang + new x in { x!(ch) | for(@y <- x) { y!(data) } } +``` + +Here `ch` does not appear in the body's top-level sends or receives — it flows through the intermediate unforgeable name `x` and is only used after evaluation. Static analysis of the unevaluated body cannot discover `ch` as a target channel in this case. Bodies containing such dynamic patterns must fall back to sequential dispatch. + +**Unforgeable name guarantee.** For bodies whose COMM channels are all unforgeable names (`GPrivate`), an additional guarantee applies beyond what static analysis provides. Unforgeable names are capability tokens created by `new` — only code that received the name through explicit communication can produce or consume on it. If a body's channels are all unforgeable and disjoint from another body's channels, even dynamic channel flow cannot create interference (the names cannot be guessed or forged by outside code): + +```rholang + new a, b in { + a!(1) | for(@x <- a){ P } // COMM on a → body₀ holds only a + | + b!(2) | for(@y <- b){ Q } // COMM on b → body₁ holds only b + } +``` + +body₀ and body₁ are provably non-interfering: neither holds the other's unforgeable name. + +**Partitioning algorithm.** At the Phase 2 boundary, the algorithm substitutes bound variables, extracts channel sets from each body's AST, and partitions into independent groups using union-find. Bodies containing unresolvable channel references (expressions, method calls, or nested `new` blocks with channel forwarding patterns) fall back to sequential dispatch: + +``` + ╔═══════════════════════════════════════════════════════════╗ + ║ ALGORITHM: Channel-Based Body Partitioning ║ + ╠═══════════════════════════════════════════════════════════╣ + ║ ║ + ║ procedure PARTITION_BODIES(deferred): ║ + ║ sequential_group ← [] ║ + ║ groups ← [] ║ + ║ channel_to_group ← {} ║ + ║ ║ + ║ for body in deferred: ║ + ║ substituted ← SUBSTITUTE(body.ast, body.matched_data)║ + ║ channels ← EXTRACT_CHANNELS(substituted) ║ + ║ ║ + ║ ── fall back if any channel is unresolvable ── ║ + ║ if channels contains BoundVar or Expr: ║ + ║ sequential_group.append(body) ║ + ║ continue ║ + ║ ║ + ║ ── union-find: merge groups sharing channels ── ║ + ║ overlapping ← {channel_to_group[ch] ║ + ║ for ch in channels ║ + ║ if ch ∈ channel_to_group} ║ + ║ if overlapping is empty: ║ + ║ group ← new Group([body]) ║ + ║ else: ║ + ║ group ← MERGE(overlapping) + body ║ + ║ for ch in channels: ║ + ║ channel_to_group[ch] ← group ║ + ║ groups.append(group) ║ + ║ ║ + ║ ── dispatch: parallel across groups, ── ║ + ║ ── sequential within each group and fallback ── ║ + ║ PARALLEL_FOR group in groups: ║ + ║ for body in group: ║ + ║ DISPATCH(body) ║ + ║ for body in sequential_group: ║ + ║ DISPATCH(body) ║ + ║ ║ + ╚═══════════════════════════════════════════════════════════╝ +``` + +The analysis is conservative: bodies with fully resolved, disjoint channel sets run in parallel; anything with unresolvable references falls back to sequential.
