+- CI coverage gate requiring at least 90% line coverage, plus
+  `scripts/coverage.sh` for the same local check.
+- Targeted tests for FFI error mapping, enum stream formatting, target
+  forwarding, altitude helpers, and azimuth helpers.
 
 ### Changed
 
@@ -18,11 +25,15 @@ Release candidate aligned with `siderust v0.10.0` (Option A altitude/event API).
 - Removed `CrossingAlgorithm`, `ChebyshevOptions`, scan-step tuning, and all FFI `_v2` dispatch paths.
 - Benchmarks simplified to the single optimized search engine (no algorithm dimension).
 - `siderust` submodule updated to the `v0.10.0` / PR #79 release line.
+- Production builds now consume official `qtty-cpp` and `tempoch-cpp` CMake
+  packages via `find_package`; local dependency development uses
+  `CMAKE_PREFIX_PATH` with a staged package install.
 
 ### Removed
 
 - Legacy `siderust_altitude_periods` / `siderust_altitude_query_t` FFI usage.
 - Public algorithm selector and Chebyshev crossing-search controls.
+- Vendored `tempoch-cpp` submodule usage from the production build path.
