    Interface ObjectHead

    Lightweight HEAD-only metadata for a single S3 object.

    Mirrors src-tauri/src/s3/inspector.rs ObjectHead (same struct reused by task 44 inspector). Used by the preview pane for size-limit checks and MIME-type routing without pulling the full inspector report.

    OCP: new optional fields (e.g. checksums, object-lock) can be added without breaking existing callers.

    interface ObjectHead {
        cacheControl: string | null;
        contentDisposition: string | null;
        contentEncoding: string | null;
        contentLength: number | null;
        contentType: string | null;
        etag: string | null;
        expires: number | null;
        lastModified: number | null;
        metadata: Record<string, string>;
        serverSideEncryption: string | null;
        sseKmsKeyId: string | null;
        storageClass: string | null;
        versionId: string | null;
    }
