v1.6.2

1.6.2

Patch release focused on workflow hardening for mixed-host execution and safer docx spec builds.

Added

• Pre-build spec path validator (scripts/validate_spec_paths.py) to verify referenced frame/contact-sheet/transcript paths before build-docx.js.
• Test coverage for spec path validation (tests/test_validate_spec_paths.py).

Changed

• SKILL workflow now defines a strict host/sandbox execution contract and requires host-side preflight when execution context changes.
• Added long-run guidance for timeout-constrained shells.
• Added strict gate requiring current-session select_frames.py output and mandatory spec path validation before doc build.
• Expanded failure-mode guidance for PATH drift and stale prior-session frame paths.
