Merkle Hash Foundation

Replace pool-local hashes with content-addressed Merkle hashes that are stable across independent Pool instances

36/36 tasks
Section 2 Complete

Hash Stability Testing

Comprehensive test suite proving Merkle hashes are stable across independent pools and free of practical collisions

23/23 tasks
Section 3 Complete

Hash-Forwarded Signatures

Embed Merkle hashes in FunctionSig and TypeCheckResult so type identity survives cross-module transport without pool access

24/24 tasks
Section 4 Complete

Hash-First Import Resolution

At import boundaries, resolve types by Merkle hash lookup (O(1)) instead of AST re-walking (O(depth)), falling back to AST only for types not yet in the local pool

29/29 tasks
Section 5 Complete

Portable Type Descriptors

Enable zero-AST type reconstruction across module boundaries via self-contained, pool-independent type descriptors

26/26 tasks
Section 6 Complete

Backend Integration

Wire Merkle hashes into LLVM, ARC, and evaluator backends to eliminate cross-pool Idx misuse and enable correct cross-module type identity

27/27 tasks
Section 7 Complete

Benchmarks & Exit Criteria

Measure and verify that Merkle pool identity delivers measurable performance improvements and zero regressions
