Severity: MAJOR

This is the build glue, not a leaf design — so any API/contract shift propagates into every HighTide BUILD.bazel. The window contains real surface changes: yosys_plugins attr on orfs.default(), new orfs_run_executable rule, orfs_blender / orfs_gds for layout viz, user_arguments / local_arguments / user_sources knobs on orfs_design, parallel-synth partition mode (kept_macros API + per-module canonicalize), quick_pins for exploration, scip / yosys / OpenROAD pin bumps (yosys 0.62 → 0.64, OpenROAD across several pins ending at 299f3015), archive_override for the ORFS pin, hermetic make. Several patch rotations against bazel-orfs's own carried patches against ORFS/OpenROAD that we mirror.

What changed

• Pin bumps — multiple ORFS and OpenROAD bumps; yosys 0.62 → 0.64 via custom registry; scip 9.2.3.bcr.1; rules_python 1.9.0; slang-elab vendored.
• API surface — yosys_plugins attr; user_arguments / local_arguments / user_sources on orfs_design; quick_pins flag; orfs_run_executable; orfs_blender + orfs_gds; kept_macros for partition scoping.
• Synth pipeline — parallel synth with per-partition macro scoping and per-module re-canonicalize, hardened-macro blackbox at canonicalize, action-name-in-progress output, JSON parser hardened against slang [N] names.
• Patches — drops carried OpenROAD/yosys patches in favor of upstream; refreshes ORFS patches 0036/0037, then drops 0037 after upstream gates dev_dependency=True; carries openroad-10384 for gallery; vendors slang-elab.
• Build — gnumake switched from zig bootstrap to cc_binary; chisel sub-workspace dropped; glibc 2.41+ compat (sed memchr patch).
• Gallery / Blender — 3D viewer of 6_final.gds, klayout under sandbox fix, gallery openroad bumped to match MODULE.bazel.

Recommendation

Plan a dedicated update window. This pin bump touches our existing carried patches (CTS-0122 patch entry on the OpenROAD git_override(patches=…) in MODULE.bazel, per CLAUDE.md — must keep applying past the new OpenROAD pin) and our defs.bzl hightide_design() wrapper around orfs_flow() (new flags like quick_pins, user_arguments, user_sources are opt-in but worth wiring up). The yosys bump (0.62 → 0.64) is the largest risk — re-verify the yosys-slang phantom-driver workaround for vortex still applies, and re-validate the close on every cached design. Recommend updating in isolation, sweeping bazel build //designs/... against the remote cache, and bisecting any regressions against the per-pin bumps in this list.
