User description

Summary

  • Upgrade the repository pin from pnpm 11.5.2 to stable patched pnpm 11.22.0.
  • Pin the shared CI bootstrap to immutable pnpm/action-setup v6.0.10 and install the explicit version before setup-node cache resolution.
  • Assert the exact toolchain and security floor before frozen dependency installation.
  • Synchronize current contributor/CI/deployment documentation and generated README test metrics.

Root cause

The composite setup previously enabled Corepack and invoked pnpm/action-setup v6.0.8 without an explicit version. The first package-manager bootstrap was therefore not structurally guaranteed to be the patched project version.

Security evidence

  • Base: 8776457, the post-fix(security): schedule daily OSV scan #454 origin/main.
  • Current stable 11.x verified from pnpm releases: 11.22.0.
  • Official advisory ranges verified: GHSA-vx52-2968-3vc6 patched at 11.11.0; GHSA-fr4h-3cph-29xv and GHSA-72r4-9c5j-mj57 patched at 11.7.0; the other inspected pnpm 11 advisories require at least 11.5.3.
  • The repository now pins 11.22.0; check-pnpm-toolchain rejects a declared version below the 11.11.0 floor and requires engines parity.
  • pnpm/action-setup is pinned to commit 0977fd99725f1db4007ccb2928dbb4e90d06cc86, v6.0.10.

Validation

  • corepack prepare pnpm@11.22.0 --activate: passed.
  • pnpm 11.22.0 frozen install: passed; lockfile unchanged; 1661 entries passed supply-chain policy.
  • toolchain check: passed on Node 24.11.1 and pnpm 11.22.0.
  • workflowPolicy.test.ts: 8/8 passed.
  • targeted Biome check and git diff check: passed.
  • ci:prepush: passed sequentially, including single-checker typecheck, i18n, docs, CSP, boundary, and native readiness.
  • README metrics regenerated: 6909+ tests / 567 files.
  • No lockfile churn.

Scope and non-goals

This PR hardens package-manager bootstrap and policy only. It does not change dependency resolutions or application runtime behavior, and it does not replace the scheduled OSV workflow from #454. Full coverage, E2E, Lighthouse, Storybook, Stryker, and native builds remain cloud-owned.

Review coverage

Configured reviewers including CodeRabbit, Graphite, CodeAnt AI, and Qodo will be checked across inline threads, top-level comments, full review bodies, nitpicks, and outside-diff findings. Every valid finding will be fixed or answered before merge.

Uncertainty

The first hosted Node 22/24 run on this new action bootstrap is pending. Local Node 24 and repository policy tests are green. Advisory applicability was checked against pnpm official GitHub advisory records; no claim is made about advisories outside that inspected set.

Summary by Sourcery

Harden repository and CI package-manager setup by standardizing on secure pnpm 11.22.0 and validating the toolchain before dependency installation.

Bug Fixes:

  • Harden pnpm bootstrapping to ensure the patched project version is installed before dependency caching and installation.
  • Enforce a minimum secure pnpm version and exact parity between the package manager and engine declarations.

Enhancements:

  • Pin the shared pnpm setup action to an immutable patched release and add executable workflow and version-policy checks to prevent bootstrap regressions.

Documentation:

  • Synchronize contributor, CI audit, CI, deployment, and project guidance with the enforced pnpm version.
  • Refresh README test metrics.

Tests:

  • Add coverage for secure pnpm version comparisons and bootstrap ordering policies.

CodeAnt-AI Description

Harden pnpm setup and enforce a secure, consistent CI toolchain

What Changed

  • Updates the project and deployment setup from pnpm 11.5.2 to patched pnpm 11.22.0.
  • CI now installs the exact pnpm version before dependency caching and verifies the toolchain before installation.
  • Rejects mismatched pnpm declarations and versions below the 11.11.0 security floor.
  • Pins the shared pnpm setup action to a specific patched release and adds tests to prevent bootstrap regressions.
  • Updates contributor, CI, deployment, and README guidance to reflect the enforced version.

Impact

✅ Fewer insecure dependency installations
✅ Consistent pnpm versions across CI and deployments
✅ Earlier, clearer toolchain configuration failures

Reviewer's Guide

This PR hardens the pnpm toolchain and CI bootstrap by pinning pnpm and pnpm/action-setup to explicit secure versions, enforcing a minimum security floor, and adding tests and documentation to keep workflow and contributor guidance in sync.

Security Hardening Review Summary

This PR effectively addresses pnpm security vulnerabilities by upgrading from 11.5.2 to 11.22.0, which patches GHSA-vx52-2968-3vc6 (11.11.0+), GHSA-fr4h-3cph-29xv, and GHSA-72r4-9c5j-mj57 (11.7.0+). The implementation includes comprehensive guardrails:

Strengths:

  • GitHub Action pinned to immutable commit hash (0977fd99725f1db4007ccb2928dbb4e90d06cc86)
  • Explicit version specified before setup-node caching
  • Toolchain validation enforces minimum security floor of 11.11.0
  • Engines field correctly synchronized with packageManager
  • Comprehensive test coverage validates bootstrap ordering and security policies

Critical Change Required:
Version comparison logic in isVersionAtLeast() contains unnecessary complexity that creates maintenance risk. The fix simplifies to standard semantic version comparison.

The PR demonstrates strong security engineering with defense-in-depth through action pinning, explicit versioning, runtime validation, and executable policy tests.

CI installs pnpm 11.22.0 before Node setup, validates the toolchain, and uses a frozen lockfile. Workflow tests verify the setup order and commands.
Developer and deployment guidance
AGENTS.md, CONTRIBUTING.md, docs/CI.md, docs/DEPLOYMENT.md, README.md
Project, contributor, CI, deployment, and README references now use pnpm 11.22.0. README test metrics use 6909+ tests.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: 🟡 Moderate · up to 51059

The PR hardens pnpm bootstrap, but its version-floor validation can still accept some older versions, so the intended security floor is not reliably enforced. This bounded security-policy correctness issue should be fixed before merge.
