    <h1>Beacon Certified PRs: How AI Agents Save Open Source (Not Kill It)</h1>
    <div class="article-meta">2026-02-15 &middot; Scott Boudreaux, Elyan Labs</div>

    <div class="article-body">
        <p>
            There's a growing narrative that <strong>vibe coding</strong> will kill open source:
            cheap code generation floods maintainers with low-signal PRs, harder security triage,
            and fewer incentives for humans to do the boring-but-critical work.
        </p>

        <p>
            That fear isn't irrational. But it's also incomplete.
            The real thing that breaks isn't code production. It's <strong>review</strong>,
            <strong>provenance</strong>, and <strong>economics</strong>.
        </p>

        <div class="callout">
            <strong>Thesis:</strong> AI agents can <em>save</em> open source if we redefine the methodology.
            We need a standard for AI-assisted contributions that is cheap to verify, hard to fake,
            license-safe, and still keeps human maintainers in control.
        </div>

        <h2>Define The Enemy: "Vibe Coding"</h2>
        <p>
            "Vibe coding" is often used to mean shipping software by describing what you want and accepting
            the model's output with minimal understanding. That's fine for prototypes.
            It's dangerous for long-lived open source libraries with large downstream blast radius.
        </p>

        <h2>What Actually Breaks In Open Source</h2>
        <p>
            Maintainers don't burn out because code is hard. They burn out because
            <strong>triage</strong> is endless:
        </p>
        <ul>
            <li>PRs with no tests and no reproduction steps</li>
            <li>license ambiguity (copy-paste blobs, incompatible deps)</li>
            <li>dependency swaps and subtle supply-chain tricks</li>
            <li>AI-generated reports that look polished but are incorrect</li>
        </ul>

        <p>
            If you lower the cost of producing code and text, you raise the cost of verification.
            That's the core asymmetry we have to fix.
        </p>

        <h2>The Fix: BCOS (Beacon Certified Open Source)</h2>
        <p>
            BCOS is a lightweight methodology we use across the Elyan Labs ecosystem
            (<a href="https://bottube.ai">BoTTube</a>, <a href="https://rustchain.org">RustChain</a>, and Beacon)
            to keep AI-assisted contributions safe and scalable.
        </p>

        <h3>BCOS Pillar 1: Signed Identity</h3>
        <p>
            Every author and reviewer should be attributable.
            GitHub handles are necessary but not sufficient. BCOS adds a Beacon identity (name + key)
            that can sign attestations about what was reviewed and why it was merged.
        </p>

        <h3>BCOS Pillar 2: Verifiable Provenance</h3>
        <p>
            Every merged PR should ship with evidence:
        </p>
        <ul>
            <li>commit SHA(s) + toolchain versions</li>
            <li>lockfiles and hashes</li>
            <li>SBOM (SPDX or CycloneDX)</li>
            <li>test results (CI links) that don't require secrets to run</li>
        </ul>

        <h3>BCOS Pillar 3: Review Tiers (L0/L1/L2)</h3>
        <p>
            Not all code needs the same scrutiny. BCOS defines tiers:
        </p>
        <ul>
            <li><strong>L0</strong>: automation only (lint/tests/license scan/SBOM)</li>
            <li><strong>L1</strong>: L0 + 2 independent agent reviews + threat model notes</li>
            <li><strong>L2</strong>: L1 + at least 1 human maintainer approval + human signature</li>
        </ul>

        <h3>BCOS Pillar 4: License Safety</h3>
        <p>
            BCOS treats licensing as a first-class CI target:
            SPDX headers where feasible, dependency license checks, and explicit attribution for copied blocks.
            If the license is unclear, the PR doesn't merge.
        </p>

        <h3>BCOS Pillar 5: Incentives (Pay For Verified Work)</h3>
        <p>
            We tie bounties to verification. On RustChain, a bounty pays only when the merge includes the
            required tier evidence and the attestation references the merged commit.
        </p>

        <div class="callout">
            Want the draft spec? It's in the RustChain repo:
            <a href="https://github.com/Scottcjn/Rustchain/blob/main/docs/BEACON_CERTIFIED_OPEN_SOURCE.md">BCOS Draft</a>.
        </div>

        <h2>How To Adopt BCOS In Your Repo (Minimal Version)</h2>
        <ol>
            <li>Add required CI checks: tests + SBOM + license scan.</li>
            <li>Add CODEOWNERS for high-risk directories (auth, wallet, payout paths).</li>
            <li>Require at least one human maintainer approval for risky changes (L2).</li>
            <li>Refuse duplicate bounty claims: pick one PR to merge, close the rest.</li>
        </ol>

        <h2>Why Beacon Matters</h2>
        <p>
            Beacon isn't "AI for coding". It's a coordination layer:
            identity, messaging, and transport standards for agents and humans.
            BCOS uses Beacon as the identity and signature layer so review and provenance can travel across repos.
        </p>

        <h2>Open Source Doesn't Die. It Evolves.</h2>
        <p>
            If we keep using a 2015 contribution methodology in a 2026 world, maintainers get crushed.
            If we upgrade the process, AI agents become leverage: more tests, faster fixes, better docs,
            and less maintainer burnout.
        </p>
