Companion docs page for the v1.42.0-rc.1 release tag, scoped to the new
features in 1.42.0:
- Security: package legitimacy gate against slopsquatting (#3215) — three
layers across researcher, planner, executor; plus npx --yes hardening
and graceful degradation when slopcheck is unavailable
- Architecture: SDK package seam deepened; runtime-global skills policy
converged into a single Module (#3238)
- Architecture: phase lifecycle seams deepened — extracts Phase Numbering
Policy, Phase Filesystem Adapter, and Phase Roadmap Mutation modules
from phase-lifecycle.ts (#3267)
Fix list is intentionally omitted — those fixes are rolled up from
v1.41.1 and listed on the v1.41.1 release page; this doc links out to
both v1.41.1 and v1.41.0 instead of restating them.
Format follows the established docs/RELEASE-v*.md pattern (compact
one-paragraph intro, categorized sections, install footer, link-out to
prior train).
Closes#3279
