One thing feels a bit weird here.

Pass the target and equivalence library to high-level synthesis so inverse ISWAP and DCX definitions are lowered before basis translation. Cover both gates at every optimization level and sort the changelog reference. Assisted-by: GPT-6 via Codex
Run continuous optimization, Solovay-Kitaev synthesis, and discrete cleanup in one staged pass manager. Disable permutation elision for native circuits so QASM exports preserve wire ordering without manual permutation repair. Reuse only discrete cleanup for exact mirrors and share the final run path. Cover all optimization levels and mirror variants with QASM2/QASM3 permutation round trips. Keep Qiskit 2.2.3 and the synthesis algorithm. Assisted-by: GPT-6 via Codex

Keep synthesis selection in the staged pipeline and reuse exact cleanup for mirrors. Preserve the inverse-gate and QASM permutation regressions from the prerequisite branch. Assisted-by: GPT-6 via Codex

Description
Use Qiskit's
SynthesizeRZRotations(gridsynth) for native Clifford+T compilation on Qiskit 2.4.2 and newer. Keep Solovay–Kitaev on older supported releases, including Qiskit 2.2.3. Select the synthesis pass withpackaging.version.Version, lower RX/RY to RZ, and synthesize rotations inside control-flow blocks.Build on the basis-preserving pipeline merged in #1093. This PR targets
mainand changes only synthesis selection, its dependency, and release notes. It remains a prerequisite for #930's encoding integration.Validation
Clifford+T, mirror, and loop tests pass on Qiskit 2.6.0 and 2.2.3 (103 on each). All lint hooks pass, with type checking on Python 3.14.
Codex assisted with implementation, updates, and checks.
