## Summary Gate 1 only for desktop release caching: - replaces canary `rust-cache` use with explicit exact-key `actions/cache/restore` + `save` - computes keys after `cargo update --workspace`, including platform, target, Rust toolchain, Cargo manifests/locks, profile/features, and native-toolchain inputs - normalizes only the desktop package version so a trusted `main` canary can warm an otherwise identical release tag - excludes Tauri bundle directories, so installers and signed artifacts are never cached - adds a restore-only `cache-proof-*` tag workflow that fails unless tag scope sees the exact default-branch cache - adds contract tests that enforce no release-workflow cache change in Gate 1 `release.yml` is intentionally unchanged. A cache miss remains the current cold canary build; the release path cannot be affected by merging this PR. ## Validation - `scripts/test-desktop-release-cache-key.sh` - `scripts/test-desktop-release-cache-workflow.sh` - `scripts/test-release-ref-contract.sh` - Ruby YAML parse of all four changed workflows - `git diff --check` - pre-push `branch-skew` ## Post-merge proof plan 1. Run each canary cold on trusted `main`, recording cache size/save time and fresh artifact inventory. 2. Run each canary warm, requiring the exact-key hit and recording restore/build time. 3. Create a disposable `cache-proof-*` tag at that same trusted `main` SHA and dispatch **Desktop release cache tag-scope proof** from the tag. 4. Do not begin Gate 2 or modify `release.yml` unless the exact tag-scope restore succeeds and cache transfer economics are favorable. --------- Signed-off-by: Wes <wesbillman@users.noreply.github.com> Co-authored-by: Carl <c7ebe626f000404285d3686e1dc74cc07cc60a9754a150041ba132e14bd3e2ec@buzz.block.builderlab.xyz>
