Breaking Contract Review

Search for breaking changes across Burrete's public and agent-visible surfaces. Do not stop after the first issue.

Surfaces

• Quick Look: bundle identifiers, extension identifiers, content types, document types, thumbnail/preview registration, Launch Services behavior, packaged app layout, and BURRETE_DEV_FLAVOR isolation.
• Browser surfaces: browser-dev shell, browser Quick Look route, quickLookFile, tokenized browser preview, dev filesystem allow-listing, local server port behavior, and Browser plugin handoff.
• Desktop app: Tauri command names, event payloads, menu actions, shell actions, viewer bridge messages, persisted runtime state, and app launch modes.
• Agent platform: scripts/burrete-agent.mjs, scripts/agent-preview.mjs, observe/action JSON shapes, session files, MCP registrations, widget manifests, and plugin skill workflow handoff.
• Molecular runtime: preview format registry, Mol*/RDKit/xyzrender assets, grid viewer behavior, text/spectrum fallback, and report rendering.
• iOS source app: runtime asset reuse, document handoff, WKWebView loading, bundle identifiers, signing assumptions, and real-device behavior.
• Release and install: package versions, updater manifests, Homebrew tap update, Bun package installer, app bundle layout, signing, and notarization.

Checks

• Identify the consumer of every changed contract.
• Confirm paired metadata files changed together.
• Confirm focused tests or smoke commands cover the affected surface.
• Flag silent shape changes, renamed actions, changed defaults, or new required fields that older callers will not provide.
• Flag changes that prove only one runtime while claiming another runtime is safe.

Output

Return only concrete breaking-change risks with file path, line number, and the consumer that would break.
