v1.0.0-rc.17

If Stim is not installed globally, replace stim below with npx stim-cli.

Fixes

• Android builds disable CMake precompiled headers by default when Stim supplies ccache, improving compiler-cache reuse across worktrees. Explicit project PCH settings are preserved; builds without Stim's ccache setup and iOS builds are unchanged. The tradeoff is slower cold C++ compilation. (9418d3d)
• The repository's benchmark harness flags missing or below-target Android compiler-cache evidence, retains failed attempts for investigation, and excludes them from published comparisons. Android preparation and preflight also require a doctor report without cost findings. (872bb1f)

Docs

• stim guide agent keeps the workflow, safety rules, and recovery actions up front. Optional cache warm-up, ABI selection, fingerprint fallback, and build-sharing details live in the build and concurrency guides. (1c420aa)
