Best possible solution:

Resolve the conflict, rerun checks, and either accept truecolor matrix output as the new SDK-visible terminal QR contract or add an explicit compatibility path before merge.

Do we have a high-confidence way to reproduce the issue?

Yes. Source shows current main uses qrcode's ANSI palette terminal renderer for default full-size output, and the inspected before/after screenshots show the dark-theme failure and the truecolor improvement.

Is this the best way to solve the issue?

Yes, with a compatibility caveat. A shared matrix renderer is the clean fix for full-size terminal QR theme stability; a legacy path is only better if maintainers decide exact ANSI-palette output or non-truecolor terminals remain supported.

Codex review notes: model internal, reasoning high; reviewed against 6cb82eaab865.

Label justifications:

• P2: This is a focused user-visible QR readability fix with limited blast radius, but it touches a shared exported helper.
• merge-risk: 🚨 compatibility: The diff changes the SDK-exported terminal QR string/color contract for existing plugin and CLI callers.
• rating: 🐚 platinum hermit: Overall readiness is 🐚 platinum hermit; proof is 🦞 diamond lobster and patch quality is 🐚 platinum hermit.
• status: 👀 ready for maintainer look: ClawSweeper has no concrete contributor-facing blocker left for this PR. Sufficient (screenshot): The PR body includes before/after screenshots that directly show the terminal QR background changing from dark gray to high-contrast white, with focused renderer tests as supplemental proof.
• proof: sufficient: Contributor real behavior proof is sufficient. The PR body includes before/after screenshots that directly show the terminal QR background changing from dark gray to high-contrast white, with focused renderer tests as supplemental proof.
• proof: 📸 screenshot: Contributor real behavior proof includes screenshot evidence. The PR body includes before/after screenshots that directly show the terminal QR background changing from dark gray to high-contrast white, with focused renderer tests as supplemental proof.

What I checked:

• Root policy read and applied: Root AGENTS.md was read fully; its ClawSweeper policy treats plugin SDK surfaces and compatibility-sensitive output changes as requiring maintainer-visible review rather than shallow cleanup. (AGENTS.md:1, 6cb82eaab865)
• Scoped SDK policy read: The plugin SDK scoped guide says this directory is the public contract between plugins and core, so the exported QR helper output change is compatibility-sensitive. (src/plugin-sdk/AGENTS.md:1, 6cb82eaab865)
• Current main still uses qrcode for default full-size output: Current main delegates default renderQrTerminal output to qrcode.toString(..., { small: false, type: "terminal" }), so the PR's shared truecolor full-size renderer is not already implemented. (src/media/qr-terminal.ts:59, 6cb82eaab865)
• PR implementation changes the shared renderer: The PR adds renderFullTerminalQr(), switches the default path to qrcode.create(text).modules, and changes the shared black-on-white sequence to 24-bit truecolor. (src/media/qr-terminal.ts:10, 2ff8d634017b)
• SDK-visible export: renderQrTerminal is exported through plugin-sdk/media-runtime, and docs show api.runtime.media.renderQrTerminal usage, so exact terminal output can affect plugin callers outside core internals. (src/plugin-sdk/media-runtime.ts:52, 6cb82eaab865)
• Dependency contract checked: [email protected]'s terminal renderer uses ANSI palette backgrounds 40/47 with per-cell reset, while its terminal entrypoint routes small:false to the big terminal renderer. ([email protected]/package/lib/renderer/terminal/terminal.js:10)

• 🦀 challenger crab: rare, exceptional readiness with strong proof, clean implementation, and convincing validation.
• 🦞 diamond lobster: very strong readiness with only minor maintainer review expected.
• 🐚 platinum hermit: good normal PR, likely mergeable with ordinary maintainer review.
• 🦐 gold shrimp: useful signal, but proof or patch confidence is still limited.
• 🦪 silver shellfish: thin signal; proof, validation, or implementation needs work.
• 🧂 unranked krab: not merge-ready because proof is missing/unusable or there are serious correctness or safety concerns.
• 🌊 off-meta tidepool: rating does not apply to this item.

Shiny media proof means a screenshot, video, or linked artifact directly shows the changed behavior. Runtime, network, CSP, and security claims still need visible diagnostics.
