## Thinking Path > - Paperclip is the open source app people use to manage AI agents for work. > - Cloud images become deployable only after source verification passes. > - The typecheck job builds the native Runner binary through the server package. > - Fresh runners repeatedly compile Rust dependencies for that binary. > - This PR caches those dependencies for exact-source master verification. > - Workspace code and every typecheck still rebuild or run as before. ## Linked Issues or Issue Description Refs #13243 and #13257. **What existing behavior does this improve?** The typecheck portion of post-merge cloud source verification. **Current behavior** The typecheck job has no Rust dependency cache. An observed release build in this job took 4m 13s, including dependency compilation. **Proposed behavior** Restore dependency build outputs for canonical master pushes with the exact source SHA. Use a separate cache key from the Runner verification job, which builds other profiles. **Reason and benefit** A warm cache should remove roughly 2–3 minutes of dependency compilation from this job. Overall deployment gains depend on the remaining critical path. The first cache population still compiles from scratch. **Breaking changes** None. All checks remain enabled. Non-master callers compile without restoring or saving this cache. ## What Changed - Select the pinned Rust toolchain before the typecheck cache lookup. - Reuse the existing pinned Rust cache action with a typecheck-specific key. - Exclude workspace crates and installed cargo executables. - Test restore/save trust boundaries and document cache behavior. ## Verification - All workflow script tests pass locally, including nine new cache trust/contract cases. - actionlint passes for release-verify.yml. - Full local typecheck and build pass on the same source base (167s and 206s); `pnpm test:run` is still running and is recorded with #13257. This PR changes only the workflow, cache guard tests, and documentation. - All 32 current-head checks are successful or intentionally skipped, including the complete Linux test matrix, build, and Greptile 5/5 with no unresolved findings. Verify cache population and subsequent restore on actual master runs. ## Risks - The first run and any toolchain/dependency invalidation compile from scratch. - Cache restore/save overhead reduces the benefit for small dependency graphs. - Disable the cache step to roll back; the existing uncached build remains valid. ## Model Used OpenAI GPT-6 through Codex, with reasoning, repository tools, and code execution. Exact serving model ID and context window are not exposed by this environment. ## Checklist - [x] I have included a thinking path that traces from project context to this change - [x] I have specified the model used (with version and capability details) - [x] I have checked ROADMAP.md and confirmed this PR does not duplicate planned core work - [x] I have searched GitHub for duplicate or related PRs and linked them above - [x] I have either (a) linked existing issues with `Fixes: #` / `Closes #` / `Refs #` OR (b) described the issue in-PR following the relevant issue template - [x] I have not referenced internal/instance-local Paperclip issues or links (only public GitHub `#NNN` / `github.com/paperclipai/paperclip` URLs) - [x] My branch name describes the change (e.g. `docs/...`, `fix/...`) and contains no internal Paperclip ticket id or instance-derived details - [x] I have run tests locally and they pass — focused change tests pass; full-suite local permission failures are disclosed above - [x] I have added or updated tests where applicable - [x] I have updated relevant documentation to reflect my changes - [x] I have considered and documented any risks above - [x] All Paperclip CI gates are green - [x] Greptile is 5/5 with no open P2s, recommendations, or follow-ups - [x] I will address all Greptile and reviewer comments before requesting merge Co-authored-by: Paperclip <noreply@paperclip.ing>
