feat(release): build iklo release binary after tests pass (epic 005 T009) - #52
Conversation
…009) Adds toolchain install, rust-cache, make test, and cargo build --release -p iklo-cli --locked to release.yml, gated on the tag validation from T008. --locked and the header-comment update came out of a self-review pass: a release artifact should fail loud on Cargo.lock drift, and the workflow's least-privilege comment still described T008's tag-validation-only state.

Hey - I've left some high level feedback:
- The Rust toolchain and rust-cache action SHAs are now duplicated between
ci.ymlandrelease.yml; consider centralizing these versions (e.g., via reusable workflows or a shared config) to avoid drift when updating them in the future. - The release workflow always runs
make testand a full release build on tag push; if tags are pushed frequently, you may want to add conditions or separate jobs to avoid unnecessary resource usage for tags that are not intended to produce release artifacts.

Re-trigger cubic
cubic-dev-ai: the release build's --locked guarantee was defeated by the preceding plain `cargo test` (via make test), which silently rewrites a drifted Cargo.lock before the --locked build ever runs. Switch the test step to `cargo test --locked` directly. Scoped to release.yml only — Makefile/ci.yml strictness is a separate concern. Co-authored-by: Claude <noreply@anthropic.com>

GitHub Actions dependency caching cache contents not signed verified cache poisoning restored files execution official documentation
💡 Result:
GitHub Actions cache contents are not signed or verified, meaning restored files can be modified by unauthorized parties if they successfully poison the cache [1][2]. Because restored files are treated as trusted inputs and can be executed within a workflow, cache poisoning can lead to arbitrary code execution in privileged workflows [3][4][1]. Official documentation and security guidance emphasize the following regarding this risk: Security Risks Cache Contents Are Not Verified: GitHub does not perform cryptographic signing or integrity verification of cache archives upon restore [1][2]. Any workflow run with read access to a cache can extract its contents, and those contents are then used directly in subsequent steps [1][2]. Cache Poisoning Path: An attacker who gains the ability to write to the cache (e.g., through compromised dependencies or code execution in an unprivileged workflow) can inject malicious files [4][5]. Because privileged workflows (such as those running on the default branch) often restore these caches, the malicious files can be executed, leading to a compromise [3][6]. Scope and Access: Cache access is largely determined by branch structure [4][6]. Caches in the default branch are generally accessible to workflows running on feature branches, creating an asymmetry that attackers exploit to move from low-trust to high-trust execution contexts [6]. Mitigation and Best Practices Treat Restored Files as Untrusted: Always assume that files restored from the cache may be malicious [3][2]. Do not store sensitive information (e.g., secrets, credentials, tokens) in the cache, as they can be read by anyone capable of opening a pull request [1][2]. Restrict Cache Write Access: Limit which workflows have permission to write to the cache [1][2]. Use trusted triggers for workflows that modify caches and leverage environment protection rules to restrict access further [1][2]. Path Validation: While the core caching mechanism remains unverified, the @actions/cache toolkit has introduced an optional, opt-in path validation feature (DownloadOptions.pathValidation) [7]. When enabled (e.g., set to 'error'), this validates that extracted files resolve within the expected directories, preventing malicious archive entries from escaping the cache paths [7]. Harden Workflows: Follow strict workflow security practices to prevent vulnerabilities like script injection or execution of untrusted code, which are common entry points for cache poisoning [1][2][8]. Never run untrusted code in the context of the default branch [4][9].

zizmor cache-poisoning GitHub Actions rust-cache cache-targets release workflow
💡 Result:
The "cache-poisoning" audit in zizmor is a security check designed to detect workflows that are potentially vulnerable to cache-based supply chain attacks [1][2]. It specifically flags workflows—often those involved in publishing artifacts—that use cache-aware actions (like Swatinem/rust-cache) without sufficient protection, which could allow an attacker with access to a repository's GitHub Actions environment to poison the cache with malicious content [1][2][3]. The vulnerability arises because GitHub Actions caches are often shared or predictable [1][2]. If a release or publishing workflow restores a cache that was populated by a less-trusted workflow (e.g., one triggered by a pull request), an attacker may be able to inject malicious dependencies or artifacts that are then included in the final, published release [1][2][3]. To remediate these findings for Swatinem/rust-cache, zizmor recommends setting the following in your workflow step [1][2]: - Use lookup-only: true: This configures the action to only restore from the cache without ever saving new state to it, effectively neutralizing the poisoning vector [1][2][3]. While some users have attempted to use save-if: false to achieve the same goal, zizmor's audit logic has historically struggled to recognize this as a sufficient mitigation, leading to potential false positives [4]. The primary, officially recommended approach within the context of zizmor's security checks remains lookup-only: true [1][2]. Beyond Swatinem/rust-cache, this audit covers numerous other popular actions that interact with the GitHub cache, such as actions/setup-node, actions/setup-python, and astral-sh/setup-uv [1][5][6]. The general principle for all these actions is to disable cache-writing behaviors (via specific action inputs) or to remove caching entirely in jobs that produce sensitive release artifacts [1][2][3].

site:docs.zizmor.sh/audits cache-poisoning lookup-only rust-cache
💡 Result:
The term cache-poisoning in the context of Swatinem/rust-cache and similar GitHub Actions refers to a security vulnerability where an attacker with access to a GITHUB_TOKEN can inject malicious payloads into the GitHub Actions cache [1]. If a subsequent workflow run restores this poisoned cache, it can lead to arbitrary code execution during the workflow runtime, which is particularly dangerous in release workflows that generate artifacts [1]. To mitigate this risk, security tools like zizmor flag the use of caching in sensitive workflows (such as those triggered by release or tag events) [1]. Using the lookup-only: true configuration for Swatinem/rust-cache is a recommended pattern to prevent this vulnerability [1]. Setting lookup-only to true ensures the action only attempts to restore existing cache entries without uploading or updating the cache during that specific workflow execution, thereby preventing an attacker from poisoning the cache with malicious build state [1].

Do not restore or save caches in the release job.
Swatinem/rust-cache restores unverified registry, git, target, and ${CARGO_HOME}/bin state. Its post step can also save state after a cache miss. Remove this step or disable it for tag pushes. lookup-only: "true" alone is insufficient; combine it with save-if: "false" if the action remains.

Replace the stale make test references.
