 ## 0.0.11-beta.3 — 2026-05-25
 
 ### Features
+- Add a `bump-platform-submodule.yml` workflow that pushes a matching `failproofai/oss` gitlink bump to `FailproofAI/platform` `main` on every merge into this repo's `main`, so the monorepo's pinned submodule commit tracks upstream automatically. Uses a `PLATFORM_BUMP_TOKEN` repo secret (fine-grained PAT, contents: read & write on `FailproofAI/platform`) for cross-repo auth, a concurrency group to serialize back-to-back merges, and a rebase-and-retry loop to stay race-safe against humans pushing to platform `main` between checkout and push (#394).
 - Add a supply-chain security CI gate: OSV-Scanner (`.github/workflows/osv-scanner.yml`) scans the resolved `bun.lock` tree against OSV.dev (GitHub/npm advisories + the OpenSSF malicious-packages feed) on every PR (incl. Dependabot bumps), on pushes to `main`, and weekly, and **blocks on any known-vulnerable or malicious dependency**. Adds a Socket GitHub App behavioral early-warning layer, an `osv-scanner.toml` allow-list for unfixable advisories, a README supply-chain status badge, and a `SECURITY.md` policy/runbook. Remediates the 18 pre-existing transitive advisories surfaced by the new gate (brace-expansion, flatted, minimatch, picomatch, postcss, vite, ws) by refreshing `bun.lock` within range, with `overrides` pinning `postcss` to the patched 8.5.x line (Next.js pins the vulnerable 8.4.31) and holding `eslint-plugin-react-hooks` at main's 7.0.1 so the refresh doesn't also bump the linter (#391).
 - Stamp `product: "failproofai-oss"` on every PostHog event across all four telemetry channels — hooks/audit (`trackHookEvent`), server (`trackEvent`), web UI (`captureClientEvent`), and npm-lifecycle install/uninstall (`trackInstallEvent`) — so OSS events stay distinguishable from any future hosted surface. The value lives in a single `POSTHOG_PRODUCT` constant in `src/posthog-key.ts`, reused by the three TypeScript channels; the standalone `scripts/install-telemetry.mjs` inlines the same literal because it can't import the TS module at install time. Honors `FAILPROOFAI_TELEMETRY_DISABLED=1` like all other telemetry (#380).
