 ### Changed
 
 - Pinned bundled native vllm.cpp to tag `v0.0.2`, commit `7020de93652ca920424a10ac5255b34810dd2f24`, moving the stable C contract from ABI 10 with 19 functions to ABI 17 with 35 functions; system libraries must match the new ABI, layouts, signatures, and exports.

 - Removed arbitrary package size and file-count caps for both crates. File counts, compressed sizes, regular-file payload sums, and SHA-256 hashes remain diagnostics, not release limits; archive inventories must match Cargo's package lists, and content, provenance, extracted-build, and downstream compatibility checks remain required.
 - Contained the entire Rust logits-processor trampoline lifetime, including final capture destruction after concurrent registration teardown, while preserving callback panic reporting and panic-payload disposal.
 - Pinned online GGUF and Safetensors metadata and body retrieval to a validated immutable commit; explicit full-SHA requests reject different metadata or offline snapshots. Validate downloads before explicitly updating requested refs, and repair hf-hub's implicit pinned-SHA ref writes on rejection without rolling back mutable aliases. Offline resolution still requires a cache ref; mutable `main` remains the default requested revision.
-- Native C API fixture failures now retain the default scheduler's failing status; an alternate scheduler run cannot make the gate pass. Callback counts are not token counts, so the upstream callback-count assertion alone does not establish token loss.
-- Optional ASan/UBSan and native-only TSan recipes select exact package/target test executables from Cargo JSON, reject empty suites, and require each exact TSan filter to pass one named test. Removed the stale release number from the CUDA/Vulkan conflict diagnostic.
-- Simplified duplicated packaging policy and release documentation, and replaced the video downloader/mux application with a minimal local-checkpoint PPM/WAV example. Narrowed the committed WAV fixture reader, repeated link-mode tests, native-gate status plumbing, and redundant build/sampling checks. Bundled builds now watch the complete native include directory. Public library APIs and centralized native-buffer safety checks are unchanged.
+- The native C API fixture preserves the default scheduler's result. Callback counts are not token counts and do not alone prove token loss.
+- Hardened optional ASan/UBSan and native-only TSan recipes to select exact Cargo test targets and require nonempty passing suites; each exact TSan filter must run one named test. Also corrected the CUDA/Vulkan conflict diagnostic.
+- Replaced the video downloader/mux application with a minimal local-checkpoint PPM/WAV example; narrowed its fixture reader and simplified duplicate maintainer checks. Bundled builds now watch the complete native include directory; public APIs and centralized native-buffer safety checks are unchanged.
 
 ### Added
 
 - `Device::{Auto, Cpu, Cuda}` selection and KV-memory controls with native precedence `num_blocks > kv_cache_memory_bytes > gpu_memory_utilization` and profile/fallback sizing.
 - Pre-tokenized `Engine::complete_tokens` with owned token output, optional copied completion metadata, and explicit truncation reporting.
 - Thread-local, exclusive `TranscriptionEngine` and `EmbeddingEngine` owners with borrowed inputs and Rust-owned transcription and row-major embedding results.
 - Separate `VideoEngine` checkpoint-set ownership, blocking generation parameters/results, and standalone `VideoMuxParams`/`VideoMuxArgv` composition that never executes ffmpeg.
-- Model-free acceptance gates for docs, tests, ABI/layout/signature/exports, native fixtures, sanitizers, link modes, packages, downstream consumers, publish dry-run, and exact MSRV. Focused Rust regressions cover callback destruction and loopback Hub branch movement/cache identity. Native-gate status, exact artifact selection, nonzero test counts and named filters, and regular-file payload accounting remain enforced by the gate implementations. These gate definitions are not evidence of an exact-candidate pass.
+- Added model-free gates for docs, workspace tests, ABI/layout/signature/exports, native fixtures, sanitizers, link modes, packages, downstream consumers, publish dry-run, and exact MSRV. Rust regressions cover callback destruction and Hub branch/cache identity; gates retain exact artifact selection, nonzero/named test assertions, and diagnostic-only payload accounting.
