 - `cargo_stable_mir_json` helper binary for cargo integration ([#47])
 - Nix derivation for reproducible builds ([#96])
 - macOS support ([#97])
+- Mutability field on `PtrType` and `RefType` in `TypeMetadata`, needed to distinguish `PtrToPtr` casts that change mutability from those that change pointee type ([#127])
+- ADR-001: index-first graph architecture for MIR visualization ([#124])
 
 ### Changed
-- Restructured `printer.rs` into a declarative 3-phase pipeline: `collect_items` -> `collect_and_analyze_items` -> `assemble_smir`, with `CollectedCrate`/`DerivedInfo` interface types enforcing the boundary between collection and assembly
-- Added `AllocMap` with debug-mode coherence checking (`verify_coherence`): asserts that every `AllocId` in stored bodies exists in the alloc map and that no body is walked twice; zero cost in release builds
-- Removed dead static-item fixup from `assemble_smir` (violated the phase boundary, misclassified statics as functions; never triggered in integration tests)
-- Rewrote `run_ui_tests.sh`: flag-based CLI (`--verbose`, `--save-generated-output`, `--save-debug-output`), build-once-then-invoke (eliminates per-test cargo overhead), arch-aware skip logic for cross-platform test lists
-- UI test runners now extract and pass `//@ compile-flags:`, `//@ edition:`, and `//@ rustc-env:` directives from test files (previously silently ignored)

 ### Fixed
-- Fixed `get_prov_ty` to recursively walk nested struct/tuple fields when resolving provenance types; previously used exact byte-offset matching which panicked on pointers inside nested structs (e.g., `&str` at offset 56 inside `TestDesc` inside `TestDescAndFn`)
-- Removed incorrect `builtin_deref` assertions from VTable and Static allocation collection that rejected valid non-pointer types (raw `*const ()` vtable pointers, non-pointer statics)
-- Replaced panicking `unwrap`/`assert` calls in `get_prov_ty` with graceful fallbacks for layout failures, non-rigid types, and unexpected offsets
-- Fixed early `return` in `BodyAnalyzer::visit_terminator` that skipped `super_terminator()`, causing alloc/type/span collection to miss everything inside `Call` terminators with non-`ZeroSized` function operands (const-evaluated function pointers); bug present since [`aff2dd0`](https://github.com/runtimeverification/stable-mir-json/commit/aff2dd0)
